The present invention relates generally to the field of interior rearview mirror systems for vehicles and, more particularly, to interior rearview mirror systems which incorporate a video display screen. The present invention also relates generally to vehicle accessory systems.
It is known to provide a video display screen at an interior rearview mirror assembly of a vehicle, such as, for example, a video display screen of the type disclosed in U.S. Pat. No. 6,428,172 for REARVIEW MIRROR ASSEMBLY WITH UTILITY FUNCTIONS, and U.S. Pat. No. 6,175,300 for BLIND SPOT VIEWING SYSTEM, which are hereby incorporated herein by reference. It has also been suggested to provide a mirror or a display which may be indexed in and out of a mirror case, such as from the bottom of the mirror case, such as also disclosed in U.S. Pat. No. 6,428,172, which is hereby incorporated herein by reference.
It is also known to provide overhead consoles at a roof region of a vehicle. The consoles may include some accessories at the forward region of the vehicle. Such consoles are typically connected to a vehicle wiring system to provide control or power to other accessories, such as lights or the like.
Drivers of vehicles, particularly larger vehicles, such as sport utility vehicles (SUVs) and the like, may be faced with a reduced or obstructed field of vision toward the rear and rearward of the vehicle as more objects, such as headrests and entertainment video screens, may block or obstruct a driver's rearward view, whether the driver uses the rearview mirror or even if the driver turns around to generally face the rear window of the vehicle. Larger SUVs may have even less visibility to the immediate rear of the vehicle. Various backup aids have been proposed to provide a display of an image of the exterior scene rearward of the vehicle for viewing by the driver.
The present invention provides an integrated overhead accessory system/module having one or more overhead cross car modules. The integrated overhead accessory system eases provision of and assembly or installation of accessories and/or accessory systems in a vehicle. The present invention also provides an interior rearview mirror assembly having a video display screen which may be extended and retracted via sliding movement laterally along or via one or more sliding members or rails positioned within the casing of the interior rearview mirror assembly. As used herein, the term video display screen describes the video display screen and the associated components and circuitry. The video display screen may slidably extend from a side of the mirror assembly and toward the driver or passenger side of the vehicle along the rail or rails to an extended or use position, whereby the video display screen is substantially extended from the mirror casing, and where the screen (and any image or icon or character or indicia or the like displayed thereon) is viewable by a vehicle occupant, such as a driver or a front seat passenger of the vehicle. When not in use, the video display screen may be retracted to or stowed in a non-use position, whereby the video display screen is positioned substantially within the mirror casing and where the screen is preferably not viewable. The video display screen may thus be slidable in a direction generally parallel to the reflective element of the mirror assembly or generally transverse to the longitudinal axis of the vehicle.
According to an aspect of the present invention, an interior rearview mirror system for a vehicle comprises a casing, a reflective element, such as positioned at a bezel portion of the casing, and a video display screen slidably mounted at the casing. The video display screen is slidable in a direction generally parallel to a length axis of the reflective element between a retracted, non-use position, wherein the video display screen is positioned substantially within the casing, and an extended, use position, wherein the video display screen is substantially extended from a side of the casing for viewing by an occupant of the vehicle.
The video display screen may be mounted to at least one sliding member which is slidable relative to the casing. The sliding member or members may be slidable along or within a sliding block mounted within the casing. Optionally, the video display screen may be slidable along at least one rail or track or guide positioned within the casing. Optionally, the video display screen may be pivotable about a pivot joint or knuckle joint when extended to the use position.
The video display screen may be manually pulled or extended or retracted or may be electronically or automatically extended or retracted (such as by a motorized action or by a spring action). The display screen may be automatically extended in response to a signal indicative of an activating event, such as an actuation of a manual or user input, an engagement of the reverse gear of the vehicle, actuation of a backup aid device or system or other reverse viewing or imaging device or system, actuation of a cabin viewing device or system, such as a baby viewing or rear seat viewing device or system or the like, actuation of a video communication device or system, actuation of a navigation system of the vehicle and/or approach of a waypoint of a programmed route of the navigation system and/or the like. The video display screen may also be manually pushed or retracted to the non-use position or may be automatically retracted in response to a signal indicative of a deactivating event, such as an actuation of a manual or user input, a curing or completion of the activating event or condition, a disengagement of the reverse gear of the vehicle, deactivation of a backup aid device or system or other reverse viewing or imaging device or system, deactivation of a cabin viewing device or system, such as a baby viewing or rear seat viewing device or system or the like, deactivation of a video communication device or system, deactivation of a navigation system of the vehicle and/or passing of the waypoint of the programmed route and/or the like.
Optionally, the video display screen may be spring-loaded or biased toward the extended position and selectably securable at the non-use position. When stowed in the non-use position, pressing laterally inward on the video display screen may release or unlatch the video display screen such that the biasing member or spring urges or moves or biases the video display screen to the extended, use position. Pressing laterally inward or pushing the video display screen into the mirror casing to the non-use position may then latch or secure the video display screen in the non-use position substantially within the mirror casing.
The mirror assembly may be mounted at a windshield of the vehicle or at an overhead accessory console or accessory module of the vehicle.
According to another aspect of the present invention, an accessory system includes at least one overhead cross car module extending at least partially across an upper portion of a vehicle and generally laterally or transverse to the direction of travel of a vehicle. The cross car module includes one or more electrical accessories and may include or may be integrated with an interior rearview mirror assembly of the vehicle. Optionally, the overhead accessory system may include two or more cross car modules, with one or more of the cross car modules including an electrical accessory. The two or more cross car modules may be electrically integrated or connected with one another, such that electrical connection to the vehicle wiring harness may be provided at one of the cross car modules, while the overhead accessory system provides electrical communication from the one cross car module to the other, such as via wires or the like extending along one or more longitudinal bracing members or the like extending between and connecting the two or more cross car modules.
Optionally, the accessory system may comprise a common accessory console that may receive one or more optional electronic sub-modules having electronic accessories or circuitry. The accessory console may also receive or connect to a common enabling module or circuitry that may interface with and control the accessories or circuitry of the sub-modules and that may provide interfacing and sharing of accessories or circuitry of the sub-modules and of the vehicle. The sub-modules thus need not include the interfacing circuitry and microprocessor controls, such that the sub-modules may be de-contented and the incremental cost of each of the sub-modules may be reduced.
Therefore, the cross car modules or overhead accessory system of the present invention may be readily installed in a vehicle and electrically connected to the vehicle wiring at the vehicle assembly plant. The overhead accessory modules or cross car modules of the present invention provide for integration of the accessories incorporated within the accessory system, such that the accessories may be readily installed to a vehicle and electrically connected to the vehicle wiring, controls, circuitry or the like via a single connection or connections at one area of the vehicle, such as at the forward portion of the headliner of the vehicle or the like. The integrated overhead accessory modules may thus provide for electrical connection and control of electronic accessories at, for example, the middle portion or rear portion of the vehicle cabin via a connection at, for example, the forward portion of the vehicle cabin.
The present invention also provides a video display screen which is extendable from a side of a mirror casing for viewing by an occupant of a vehicle. The video display screen may be positioned substantially within the casing when not in use, and may be extended substantially outward from the casing toward the driver or passenger side of the vehicle when viewing of the video display screen is desired. By slidably positioning the video display screen within the mirror casing, the present invention provides for a large video display screen to enhance viewing of the images displayed thereon by the driver or other occupant of the vehicle, while having a minimal affect on the size of the casing. The casing is formed to be wide enough to receive the video display screen therein, with the casing being at least as wide as the height dimension of the video display screen.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.
FIGS. 16A-C are perspective views of another interior rearview mirror assembly incorporating a video display screen in accordance with the present invention;
Referring now to the drawings and the illustrative embodiments depicted therein, an interior rearview mirror assembly 10 for a vehicle includes a casing 12, a bezel portion 14 and a reflective element 16 positioned at and at least partially within the casing and/or bezel portion (
As can be seen in
Because the video display screen is positioned within the mirror casing and is slidable along the length axis and outward from a side of the mirror casing, the video display screen may comprise a large, rectangular-shaped video display screen to enhance viewing of the video display screen by the driver or occupant of the vehicle. The mirror casing is formed to be at least as wide or tall as the height dimension of the video display screen. The width of the video display screen may be selected depending on the desired size of the viewing area and on the lateral space within the associated mirror casing. Preferably, the video display screen is a least approximately two inches wide, more preferably at least approximately 2.5 inches wide, and most preferably at least approximately three inches wide. The video display screen thus may fit or slide laterally within the mirror casing and may provide an increased viewing area without requiring a substantial increase to the size of the mirror casing.
Although shown and described as slidably extending from a side or portion of an interior rearview mirror assembly, the display screen of the present invention may extend from a portion of the mirror assembly elsewhere at or on the mirror assembly, or from a portion of the support structure of the mirror assembly (such as in a single ball mounting member arrangement), such as a support structure of the types described in U.S. Pat. No. 6,087,953, which is hereby incorporated herein by reference. Optionally, the display screen device of the present invention may be positioned at or at least partially within a casing or housing of a windshield electronics module or accessory module, such as those described in U.S. patent application Ser. No. 10/355,454, filed Jan. 31, 2003 by Schofield et al. for VEHICLE ACCESSORY MODULE (Attorney Docket DON01 P-1050); and/or Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which are hereby incorporated herein by reference, or an overhead console or module or the like, such as those described below with respect to
Frame 22 of video display screen device 18 substantially surrounds and encases video display screen 20 and may include an outer grasping portion or end portion 22a. End portion 22a and casing 12 may be correspondingly formed such that end portion 22a generally nests partially within casing 12 when video display screen device 18 is in its retracted position. Also, end portion 22a may be formed to generally correspond with the exterior surface of casing 12, such that end portion 22a may provide a generally flush, uniform appearance to the side of the mirror casing when the device is fully retracted. As best seen in
Video display screen 20 may be slidable or extendable/retractable via sliding movement of a rail or guide or track or the like relative to a receiving block or guide or the like that slidably receives or guides the rail or guide or track or the like as the display screen extends and retracts relative to the mirror casing. In the illustrated embodiment of
Optionally, as shown in phantom in
Video display screen 20 may comprise any type of video screen and is operable to display images in response to an input or signal from a control or imaging system. For example, the video display screen may comprise a multi-pixel liquid crystal display (LCD), preferably a thin film transistor multi-pixel liquid crystal display, or the screen may comprise a multi-pixel organic electroluminescent display or a multi-pixel light emitting diode (LED), such as an organic light emitting diode (OLED) or inorganic light emitting diode display or the like, or a passive reflective and/or backlit pixelated display, or an electroluminescent (EL) 20 display, or a vacuum fluorescent (VF) display or the like. For example, video display screen 20 may comprise a video screen of the types disclosed in U.S. Pat. Nos. 6,428,172 and 6,420,975, and/or U.S. patent application Ser. No. 09/585,379, filed Jun. 1, 2000 by Hutzel et al. for REARVIEW MIRROR ASSEMBLY WITH UTILITY FUNCTIONS (Attorney Docket DON01 P-817); Ser. No. 10/207,291, filed Jul. 29, 2002 by Hutzel et al. for REARVIEW MIRROR ASSEMBLY WITH UTILITY FUNCTIONS (Attorney Docket DON01 P-1010); Ser. No. 10/307,929, filed Dec. 2, 2002 by Hutzel et al. for AN INTERIOR REARVIEW MIRROR SYSTEM INCLUDING A PENDENT ACCESSORY (Attorney Docket DON01 P-1052); and/or Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which are hereby incorporated herein by reference. Optionally, the display screen device may provide a three dimensional aspect to the information being displayed.
Video display screen device 18 may be in communication with or may receive an input or signal from a corresponding imaging sensor or camera or imaging system and may display the image or images provided by the input or signal on the video display screen 20. As shown in
Control 30 is operable to control video display screen 20 in response to an input or signal, such as a signal received from one or more cameras or image sensors of the vehicle, such as a video camera or sensor, such as a CMOS imaging array sensor, a CCD sensor or the like, such as the types disclosed in commonly assigned, U.S. Pat. Nos. 5,550,677; 5,760,962; 6,097,023 and 5,796,094, which are hereby incorporated herein by reference, or from one or more imaging systems of the vehicle, such as a reverse or backup aid system, such as a rearwardly directed vehicle vision system utilizing principles disclosed in U.S. Pat. Nos. 5,550,677; 5,760,962; 5,670,935; 6,201,642; 6,396,397; and/or 6,498,620, and/or in U.S. patent application Ser. No. 09/199,907, filed Nov. 25, 1998 by Bos et al. for WIDE ANGLE IMAGE CAPTURE SYSTEM FOR VEHICLE (Attorney Docket DON01 P-676); and Ser. No. 10/010,862, filed Dec. 6, 2001 by Bos for PLASTIC LENS SYSTEM FOR VEHICLE IMAGING SYSTEM (Attorney Docket DON01 P-954), which are hereby incorporated herein by reference, a trailer hitching aid or tow check system, such as the type disclosed in U.S. patent application Ser. No. 10/418,486, filed Apr. 18, 2003 by McMahon et al. for VEHICLE IMAGING SYSTEM (Attorney Docket DON01 P-1070), which is hereby incorporated herein by reference, a cabin viewing device or system, such as a baby viewing or rear seat viewing camera or device or system or the like, such as disclosed in U.S. Pat. No. 5,877,897 and/or U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which are hereby incorporated herein by reference, a video communication device or system, such as disclosed in U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which is hereby incorporated herein by reference, and/or the like. Optionally, the video display screen may also or otherwise serve as a screen for a navigation system of the vehicle or the like, such as a GPS navigation system, such as a known navigation system or such as a navigations system of the type discussed below. The display screen may be operable to display video images and/or may display icons, characters, letters, text or other indicia, and may provide a menu driven display and control for the navigation system or the like (as discussed below), without affecting the scope of the present invention.
As shown in
Optionally, the display screen may include contrast enhancement or anti-glare coating or means, such as described in U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which is hereby incorporated herein by reference. For example, the display screen may include polarization means or filters or coatings, such as known in the art, to enhance visibility of the display during high ambient light levels, such as may be encountered on a sunny day. Optionally, the display screen may include other anti-glare coating or other anti-glare means, without affecting the scope of the present invention.
Because the video display screen 20 may be pulled or moved near or into the driver's forward field of view (if it extends toward the driver's side of the vehicle), and thus may interfere with the driver's forward vision, when the display screen is in the extended position, video display screen device 18 is preferably occasionally extended and/or activated for viewing, and retracted to the non-use position when not in use. Frame 22 and video display screen 20 may be manually pulled to the extended, use position by the driver or occupant of the vehicle, and may be manually pushed back into the retracted, non-use position when the desired viewing is completed. The video display screen and/or associated imaging device or system may be actuated in response to the frame and video display screen being moved to the extended position or may be actuated via one or more user actuatable controls or buttons or the like on the frame of the video display screen device or elsewhere on the mirror assembly or vehicle, or in response to other types of activating events, such as discussed below.
Optionally, the frame and video display screen may be spring-loaded or biased or spring actuated, whereby a spring or other biasing member may function to bias or urge or assist the frame and screen toward the extended position. In such an application, the spring or biasing member may be overcome by pushing the frame into the mirror casing to the non-use position, whereby a latch mechanism or the like may retain the frame in the non-use position. The frame may then be pressed inward to release the latch and to allow the biasing member or spring to move or urge or assist the frame and video display screen to the extended position. Such mechanisms are conventional and well known.
Optionally, frame 22 and video display screen 20 may be extended electronically, such as via a driving device or mechanism (not shown), such as via a linear actuator, a solenoid device, a rack and pinion device, an electrical drive motor or actuator, such as the types disclosed in U.S. Pat. Nos. 6,116,743 and/or 6,390,635, which are hereby incorporated herein by reference, a non-armature electrical motor, a shape memory alloy (SMA) device, a NanoMuscle™ device, an electrically induced stress-strain device or actuator, a bio-material and/or the like.
For example, and as shown in
In the illustrated embodiment of
The belt drive mechanism 47 includes a drive motor 47a that is mounted to base portion 44 and that is operable to rotatably drive a pulley 47b, which in turn drives a belt or band 47c to rotate a second pulley 47d. Second pulley 47d is mounted to or secured to pinion 46a, such that rotational driving by motor 47a causes rotation of pinion 46a, which in turn causes translational movement of rod 24′ and frame 22′ and the display screen relative to base portion 44. The display screen device and/or mirror assembly may include or utilize mechanical movement means and/or sound dampening means to ensure quiet, preferably near silent or silent, extension/retraction of the display screen. Optionally, the drive mechanism may deliver a slight sound to provide the driver with a cognizant awareness (in addition to the visible cue or prompt) of the extension/retraction of the display screen.
The frame and the video display screen thus may be extended and retracted via belt drive mechanism 47 and rack and pinion mechanism 46. The belt drive mechanism provides a smooth drive movement and may provide reduced noise to the drive mechanism. The rack and pinion arrangement or mechanism enables the powered or driven mechanism to be manually overridden by pulling or pushing the display screen in the desired direction (which may cause the belt to slip on the pulleys if the motor is not operating). Such a manual override may be desired to allow the display screen to be operated without the electric drive in case of failure of the drive motor. Optionally, the drive system may include sensors for sensing initial movement of the video display screen in either direction, whereby the drive motor may be actuated to move the display screen in response to detection of such initial movement. For example, a sensor may detect an initial inward movement of the display screen, such that a small push of the extended display screen toward the mirror assembly may turn on the electric drive which then may retract the display screen.
As can be seen with reference to
Optionally, and alternately, for example, a conventional solenoid may be used for a drive motor. Preferably, however, particularly for substantially silent operation, a shape memory alloy device or electrically induced stress-strain actuator or the like may be implemented, such as a NanoMuscle™ actuator, such as a 70 gram High Speed/High Efficiency Linear Actuator, a 125 gram High Speed/High Efficiency Linear Actuator, or a 195 gram High Speed/High Efficiency Linear Actuator, all of which are commercially available from NanoMuscle, Inc. of Antioch, Cal. Such electrically induced stress-strain linear actuators comprise a selection and/or combination of metallic elements, typically bimetallic elements, such as bimetallic alloys, which may contract in response to electrical actuation and may extend or return to their original state when the electrical actuation is removed. More particularly, such electrically induced stress-strain actuator, such as the NanoMuscle™ actuator or the like, contracts in response to one or more electrically resistive shape memory alloy wires contracting as they are heated with application of a suitable voltage. Often such linear actuators may incorporate a spring or other biasing member or return force device or mechanism to urge or assist the actuator to its original, non-contracted state when the electrical actuation is removed. The actuator may be mounted at the mirror assembly such that contraction of the actuator results in a corresponding retraction of the frame and video display screen to the retracted, non-use position or a corresponding extension of the frame and video display screen to the extended, use position, depending on the application of the actuator. Other such contracting or extending devices may be implemented, and may comprise metallic or polymeric components, without affecting the scope of the present invention. Such shape memory alloy devices thus provide substantially silent operation, since there is substantially no parts or gears or the like moving relative to one another during operation. It is further envisioned that pivotal movement of the video display screen about a pivot axis or joint, as discussed above, may be selectably electronically controlled via a rotational drive motor or the like, without affecting the scope of the present invention.
Optionally, and with reference to
The sliding or pivotal or other movement of the frame and display screen may selectably occur in response to a manual or user input, such as actuation of a user interface control or button (not shown) at the interior rearview mirror assembly or a voice command or input, or the display screen may extend automatically, such as in response to another activating event or triggering event or other dynamic event or events. For example, the display screen may be automatically extended and activated in response to an engagement of the reverse gear of the vehicle or actuation of a backup aid or other reverse viewing system, such as a reverse viewing system utilizing principles disclosed in U.S. Pat. Nos. 5,550,677; 5,760,962; 5,670,935; 6,201,642; 6,396,397; and/or 6,498,620, and/or U.S. patent application Ser. No. 09/199,907, filed Nov. 25, 1998 by Bos et al. for WIDE ANGLE IMAGE CAPTURE SYSTEM FOR VEHICLE (Attorney Docket DON01 P-676); and/or Ser. No. 10/010,862, filed Dec. 6, 2001 by Bos for PLASTIC LENS SYSTEM FOR VEHICLE IMAGING SYSTEM (Attorney Docket DON01 P-954), and/or U.S. patent application Ser. No. 10/418,486, filed Apr. 18, 2003 by McMahon et al. for VEHICLE IMAGING SYSTEM (Attorney Docket DON01 P-1070), which are hereby incorporated herein by reference, actuation of a cabin viewing device or system, such as a baby viewing or rear seat viewing device or system or the like, such as the types disclosed in U.S. Pat. No. 5,877,897 and/or U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Doclcet DON01 P-869), which are hereby incorporated herein by reference, actuation of a video communication device or system, such as a video communication device of the types disclosed in U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which is hereby incorporated herein by reference, actuation of other telephone or communication systems (where the display screen may extend to display telephone numbers or recently called numbers or other information or the like), actuation of a navigation system of the vehicle, such as a navigation system of the types described in U.S. Pat. No. 6,477,464, and U.S. patent application Ser. No. 10/456,599, filed Jun. 6, 2003 by Weller et al. for INTERIOR REARVIEW MIRROR SYSTEM WITH COMPASS (Attorney Docket DON01 P-1076); Ser. No. 10/287,178, filed Nov. 4, 2002 by McCarthy et al. for NAVIGATION SYSTEM FOR A VEHICLE (Attorney Docket DON01 P-1051); Ser. No. 10/645,762, filed Aug. 20, 2003 by Taylor et al. for VEHICLE NAVIGATION SYSTEM FOR USE WITH A TELEMATICS SYSTEM (Attorney Docket DON01 P-1103); and Ser. No. 10/422,378, filed Apr. 24, 2003 (Attorney Docket DON01 P-1074), which are hereby incorporated herein by reference, and such as discussed below, a vehicle system or device status or warning system (where the display screen may be automatically extended to display a warning or alert to the driver in response to a condition being detected, such as the driver's seatbelt being unfastened (and optionally with the vehicle being in gear or moving or the like), a high oil temperature or pressure, a low tire pressure (such as in response to a tire pressure management system (TPMS), such as the types described in U.S. Pat. Nos. 6,294,989; 6,445,287; and/or 6,472,979, and/or in U.S. patent application Ser. No. 10/232,122, filed Aug. 30, 2002 (Attorney Docket DON01 P-1003); and Ser. No. 10/279,059, filed Oct. 23, 2002 (Attorney Docket DON01 P-1027), which are hereby incorporated herein by reference), a low fuel level and/or the like), or any other activating event or triggering event or condition or detection or dynamic event and/or the like, without affecting the scope of the present invention. The outward movement or extension of the display screen not only provides the display of information at a position that is readily viewable by the driver of the vehicle, but the outward movement of the display screen also provides a visual cue or prompt, and optionally an audible sound associatable with a sliding motion, to catch the driver's attention and reinforce viewing of the display screen so that the driver can readily view the information being displayed at the display screen. Similarly, the video display screen may be automatically retracted to the non-use position in response to a manual or user input, or in response to completion of or curing of the activating or triggering event or deactivation of the system or device associated with the activating or triggering event, such as shifting of the vehicle out of reverse, deactivation of a rearward viewing device or system, deactivation of a cabin viewing device or system, deactivation of a video communication device or system or disconnection of the telephone connection or conversation, deactivation of a navigation system of the vehicle or arrival at a particular waypoint or destination (as discussed below), or a correction or curing of the system condition, such as fastening of the seatbelt, and/or the like.
The display screen may be manually moved to its retracted position when the driver no longer wants to view the screen, even if the activating event has not yet completed. This allows the driver to override the automatic extension and retraction, such as when the driver no longer wants to view the information relating to the activating event, without disturbing or adversely affecting the automatic extension controls and components. For example, if the driver chooses to ignore a warning that the tire pressure is low (or other warning or information display or the like), the driver may manually move the display screen to its retracted position. The manual movement may be accomplished via pushing the display screen into the mirror assembly, or pressing or actuating a user input or button or the like to cause the retraction of the display screen, or providing a voice command to the system to cause the retraction/override of the display screen device. Optionally, the drive system of the display screen device may include sensors for sensing initial movement of the display screen in either direction, whereby the drive motor or the like may be actuated to move the display screen in response to detection of such initial movement. For example, a sensor may detect an initial inward or outward movement of the display screen, such that a small push or pull of the display screen may activate the electronic drive motor or system which then retracts or extends the display screen.
Optionally, the display screen may be manually extended by the driver or occupant of the vehicle even if a dynamic or activating or triggering event has not occurred. The driver may then select a desired function of the display screen when it is extended. Optionally, the display screen may display a menu for the driver to select from when the display screen is extended manually. The menu or menus may be in the form of text displays, graphic displays, video displays, iconistic displays, indicia displays and/or the like. The driver may then select from the menu by touching or actuating a user input or by providing a voice command or the like to cause the display screen to display information or video or the like pertaining to the selected function or system or accessory. For example, the driver may cause the display screen to display the rear vision system video or images even though the vehicle is not in reverse by manually extending the display screen and manually selecting the rear image display function. The manual extension and activation may be accomplished by manually pulling or moving the display screen or by actuating a user input or by providing a voice command (such as “open” or “extend”) or the like.
The video display screen thus may be operable to automatically or manually extend to display information or video pertaining to a selected or triggering event or function. For example, video display screen 20 may be in communication with a camera or imaging sensor or system operable to capture images of an area rearward of the vehicle. Video display screen 20 may then be extended in response to engagement of the reverse gear of the vehicle or activation of the rearward viewing device or system, where the video display screen 20 may be operable to display images representative of the scene and events occurring rearward of the vehicle, such that the driver may view the video display screen as the vehicle is reversed. When the vehicle is shifted out of reverse, the video display screen may be automatically retracted to its non-use position. As discussed above, frame 22 and video display screen 20 may be extended and retracted via a linear actuator, a solenoid device, a rack and pinion device, an electrical drive motor, a non-armature electrical motor, a shape memory alloy device, a NanoMuscle™ device, an electrically induced stress-strain device, a bio-material and/or the like, without affecting the scope of the present invention. Optionally, the video display screen and frame may be manually pulled from the mirror casing, but the video display screen device may limit or substantially preclude sliding movement of the frame toward the extended position unless the vehicle is shifted into the reverse gear or some other activating event occurs, such as actuation of a rearward viewing device or system, actuation of a cabin viewing device or system, such as a baby viewing or rear seat viewing device or system or the like, actuation of a video communication device or system, actuation of a navigation system of the vehicle and/or the like, without affecting the scope of the present invention. The manual operation of the video display screen device may override the automatic extension and retraction of the display screen without adversely affecting the automatic or electronic controls or devices or systems.
It is further envisioned that the control system of the display device may extend and retract the display screen in response to multiple activating or triggering events or a hierarchy of events, and may operate in a hierarchical manner where certain events control or override other events. The display screen device may be linked to the triggering event and thus may be operable to display information or video images or the like pertaining to the system or device or function associated with the activating or triggering event. For example, when the reverse gear is engaged, the display screen may extend automatically and display the captured images or video of the scene rearward of the vehicle (as captured by a video camera or imaging sensor or the like at the rear portion of the vehicle). If, on the other hand, a user activates a phone system or communication system, such as by pressing a button or actuating an input or providing a voice command or the like, the display screen may extend and may display useful information, such as menus to select from or telephone numbers (such as a directory or a list or recently called numbers) or the like, to the user of the communication system. Optionally, if a telephone call is received by the telephone or communication system, the display screen may extend to display a caller identification function or other pertinent information or the like or video images of the caller (if associated with a video communication system) or the like to the driver or user.
In situations where the display screen is already extended and displaying information to the driver pertaining to an activating event, such as, for example, displaying the rear seat area of the vehicle when a cabin monitor is activated, the display screen may change or adjust or reconfigure the display to correspond to another activating event, such as, for example, a warning or alert that the vehicle is low on fuel or the like. The hierarchy of activating events may determine which events may override other events, such that an important event, such as a rear vision system display while the vehicle is in reverse, is not overridden by an event that can wait until after the first event (backing up the vehicle) is completed, such as a navigational instruction pertaining to the vehicle navigation system or other information or video. The display screen device thus may comprise a dynamic extension system that automatically extends the display screen in response to dynamic events or functions. However, the driver or occupant of the vehicle may override the event hierarchy at any time by manually activating another one of the triggering events or systems or functions. For example, if the driver is backing up the vehicle, but is not using the rear vision system display, the driver or another occupant may manually activate the navigation system or telephone system or cabin monitoring system or the like to change the display to correspond to the newly activated system. The manual override may be accomplished via manual actuation of a user input or the like or via a voice command or the like.
As described above, the display screen may be extended in response to an activating event associated with a vehicle navigation system and/or a point of interest compass system, such as navigation systems/compass systems of the types described in U.S. Pat. No. 6,477,464, and U.S. patent application Ser. No. 10/456,599, filed Jun. 6, 2003 by Weller et al. for INTERIOR REARVIEW MIRROR SYSTEM WITH COMPASS (Attorney Docket DON01 P-1076); Ser. No. 10/287,178, filed Nov. 4, 2002 by McCarthy et al. for NAVIGATION SYSTEM FOR A VEHICLE (Attorney Docket DON01 P-1051); Ser. No. 10/645,762, filed Aug. 20, 2003 by Taylor et al. for VEHICLE NAVIGATION SYSTEM FOR USE WITH A TELEMATICS SYSTEM (Attorney Docket DON01 P-1103); and Ser. No. 10/422,378, filed Apr. 24, 2003 (Attorney Docket DON01 P-1074), which are hereby incorporated herein by reference. In such applications, the display screen may be extended to display navigational information, such as driving instructions or compass heading or a map or the like, to the driver of the vehicle as the driver negotiates a programmed or desired route. The display screen may be extended and activated to display the instructions and/or compass heading and/or map in accordance with the geographical position of the vehicle, such as detected by an in-vehicle or vehicle-based navigation system detector, such as a global positioning system (GPS) or circuitry and/or the like. The vehicular global positioning system may comprise an in-vehicle GPS antenna and a GPS receiver/signal processor that receives a satellite communication to determine the geographic location of the vehicle, as is known in the art. Such global positioning system receivers/processors, sometimes referred to as a GPS chip set, are available from various suppliers, such as, for example, Motorola of Schaumburg, Ill. and Trimble Navigation of Sunnyvale, Calif. The display screen thus may be extended and activated as the vehicle approaches a waypoint or milestone in the programmed route of the vehicle navigation system. The display screen thus not only provides the instructions and/or map to the driver, but the extension of the display screen provides a visual cue or prompt to alert the driver or catch the driver's attention so that the driver knows to look at the screen to get the next instruction at an appropriate time before the vehicle arrives at the waypoint or milestone. The display screen may then retract to its retracted position after the vehicle arrives at the next waypoint or milestone. The global positioning system thus may determine when the geographic position of the vehicle approaches a waypoint and may then trigger extension of the display in conjunction with the vehicle navigation system or in conjunction with a vehicle database or navigation system database.
For example, a user or driver may enter a desired destination into the navigational system and the navigational system may determine an appropriate route for the vehicle to travel from its initial or current location until it arrives at the desired destination. As is known in the art, the route may be determined to provide a shortest distance route or quickest route or may be determined in accordance with other parameters as may be selected by the user. When the vehicle begins the journey, the display screen may extend and activate to display a first instruction or set of instructions or map, such as “Take Oak Road West and turn right at Maple Street and head North on Maple Street”. The display screen may remain extended until the driver of the vehicle has carried out the instructions and passed the first waypoint or milestone (for example, the intersection of Oak Road and Maple Street). The display screen may then display the next instruction (such as, for example, “Take Maple Street North to Interstate 96”) and may then retract until the vehicle approaches the next waypoint. As the vehicle approaches the next waypoint, such as about one or two miles before the next waypoint (or any other distance as may be desired), the display screen may again extend and be activated to display or re-display the next instruction or set of instructions and/or map to the driver. For example, the display screen may extend (which, as discussed above, provides a visual cue to the driver that he or she is approaching the next waypoint or milestone of the journey) and may be activated to display a second instruction or set of instructions and/or map to the driver, such as “Enter Interstate 96 and take Interstate 96 East to Exit 43”. While the vehicle is on the on-ramp or thereabouts, the display screen may display the next set of instructions or map (for example, “Take Interstate 96 East to Exit 43”), and then may retract to its retracted position as the vehicle is driven onto Interstate 96 and heading east on Interstate 96. The display screen thus only extends and is activated when the instructions are desired, and is retracted between waypoints so as not to be a bother or nuisance to the driver in situations where no further instructions are necessary. The extension of the display screen provides a visual cue to the driver to look at the screen for the next instruction at a particular time when the next instruction may be highly desirable or necessary to the driver.
The time or distance before the next waypoint that the display screen extends may be selected or pre-set by the manufacturer of the vehicle or mirror assembly or navigational system or the like. Optionally, the time or distance before the next waypoint that the display screen extends may vary depending on the vehicle speed or the particular road or highway on which the vehicle is traveling. For example, if the vehicle is traveling on a highway at about 70 mph, the display screen may extend and activate approximately two miles before the next waypoint to allow the driver sufficient time to get into the appropriate lane for exiting the highway. However, if the vehicle is traveling on a road at about 30 mph, the display screen may extend and activate approximately 0.5 to 1 miles before the waypoint, because at the slower speed, such a distance provides ample time for the driver to prepare to execute the next driving instruction. The vehicle speed may be determined by wheel sensors or speed sensors of the vehicle or by the global positioning system or the like, or the speed may be estimated based on the known speed limit for the particular road that the vehicle is traveling on (where the particular speed limit may be extracted from a database of such speed limits). It is further envisioned that the display screen may extend and activate at different locations or distances relative to the approaching waypoint in response to the driving conditions (as may be detected by a rain sensor or other vision system or as may be provided by the global positioning system or the like), traffic conditions (as may be provided by a vehicle vision system or object detection system or headlamp control system or the like), and/or hazardous conditions (as may be provided by vehicle vision systems or vehicle status systems or collision avoidance systems, such as the types disclosed in U.S. Pat. No. 6,411,204, which is hereby incorporated herein by reference) and/or the like, in order to provide sufficient time to the driver to prepare to execute the next set of instructions.
Optionally, the display screen may extend when the vehicle is not moving or stopped (as determined by a vehicle speed sensor or by a global positioning system or the like), such as at a stop light or the like, and may display information to the driver at a time when the driver is able to fully focus on the information being displayed. For example, the display screen may display driving instructions or location information or the like pertaining to the programmed route or next waypoint, or the display screen may display trip statistics or the like, such as time traveled, distance traveled, estimated arrival time, and/or the like. Optionally, the display screen may display other information that may be of interest to the driver, such as information pertaining to the geographic position of the vehicle (such as, for example, if the vehicle is stopped by a particular store or restaurant, the display may display an advertisement of the store or restaurant) as may be provided via the global positioning system database or concierge service or the like, or may display any other type of information to the driver at a time when the driver has time to look at and read/understand the information while the vehicle is stopped. The display screen may be manually retracted when the driver is finished viewing the information being displayed or may be automatically retracted upon movement of the vehicle or a period of time after onset of movement of the vehicle. The extension of the display screen when the vehicle is stopped may be manually overridden to avoid extension if such extension is not desired.
Optionally, the navigational system may be programmable or selectable or operable to allow the driver to select at which waypoint or milestone along the journey that the display screen will be extended and be visible and readable by the driver to provide instructions such as those set forth above. For example, the driver of the vehicle may be well aware of how to get onto Interstate 96 and to head east on Interstate 96 to head toward the desired destination, but may not know where to exit and where to go after exiting the interstate. The driver thus may not want the display screen to extend and provide the initial instructions that are already known to the driver while the driver is driving the vehicle toward and onto and along Interstate 96. At the onset of the journey or while the driver is setting the navigation system, the navigation system may receive inputs from the driver that are indicative of a desired start point or waypoint for the instructions to begin, and the display screen may remain retracted and deactivated until the geographical position of the vehicle (as detected by the navigational system detector) approaches the selected waypoint or milestone at which the display of the instructions or maps will begin (or unless the display screen is extended and activated in accordance with a different activating or triggering event). As the vehicle approaches the selected waypoint or milestone, the display screen may extend and may be activated to display the appropriate instructions and/or map. For example, the display screen may remain retracted while the vehicle travels toward and onto and along Interstate 96. When the vehicle is approximately one to two miles (or other distance, as desired or depending on other parameters as discussed above) from exit 43, the display screen may extend to alert the driver, and may display the instruction: “Take Exit 43 and turn left Pine Street. Take Pine Street North to Elm Street.” After the vehicle has turned onto Pine Street, and the system has detected that the waypoint has been reached, the display screen may again retract (and optionally may briefly display the next driving instructions or compass heading or map before it retracts) until the vehicle approaches the next waypoint, for example, the intersection of Pine Street and Elm Street. As the vehicle approaches the next waypoint, the display screen may again extend and display the next instruction or set of instructions and/or map at the appropriate time or location before the next waypoint. The display screen thus may remain retracted throughout the known or familiar part of the journey, and then may extend to alert the driver or catch the driver's attention and to provide the appropriate instructions and/or compass heading and/or map to the driver at the appropriate time as the vehicle approaches the next waypoint or milestone in the journey or trip.
Optionally, if the driver is familiar with the route beyond what was initially thought when programming or setting or selecting the route, the driver may at any time manually override the system to retract the display screen when it extends to provide the next instructions or map. For example, the driver may actuate an input or control at the display screen or at the steering wheel or at the mirror assembly or elsewhere in the vehicle (such as may be provided at a keypad or touch pad interface, preferably menu driven as described herein) or may provide a vocal message or voice command to cause the display screen to retract and deactivate if it is not desired or needed. The driver may actuate or provide such inputs to select the destination or initial waypoint or to override the navigation system or the like or to enter telephone numbers (for a communication system) or street addresses or the like. The navigation system thus may retract the display screen when it is not needed or desired by the driver. As the vehicle approaches the next waypoint or milestone in the journey, the display screen may again extend and provide the next appropriate instruction and/or map to the driver of the vehicle. Likewise, if the driver is less familiar with the route, or merely wants to check the location or progress or the like, the driver may override the system to cause the display screen to extend and activate to show the next instructions or directional heading or a map or any trip statistics that the driver may want to review. For example, the driver may actuate an input or control at the display screen or at the steering wheel or at the mirror assembly or elsewhere in the vehicle or may provide a vocal message to cause the display screen to extend and activate to display such instructions, heading, maps or information or the like.
If a particular waypoint is passed or missed, such that the vehicle is no longer on or following the programmed route, the system may extend the display screen to alert the driver and may display a warning that a turn or exit or the like was missed, and may provide instructions as to how to get back on the programmed route, such as described in U.S. patent application Ser. No. 10/645,762, filed Aug. 20, 2003 by Taylor et al. for VEHICLE NAVIGATION SYSTEM FOR USE WITH A TELEMATICS SYSTEM (Attorney Docket DON01 P-1103), which is hereby incorporated herein by reference. The display screen may be extended in this manner even during the initial or familiar part of the route to alert the driver that he or she has departed from the desired route.
The display screen thus may extend to alert the driver that information or video pertaining to one of the activating or triggering events or waypoints is being displayed. The driver's attention is thus drawn to the display screen when such information is being displayed, such that the driver is not likely to miss or overlook or ignore such information. The display screen thus provides a driver prompt that prompts the driver to look at the display screen for new information that is being displayed thereon. Optionally, an audible prompt may be provided to alert the driver to look at the display screen for the instructions. Optionally, the navigation system and/or display screen device may be operable to turn down the volume of other vehicle systems, such as a radio or communication system or the like, when the display screen is extended, such that the driver may focus on the display screen or so that the driver may readily hear and recognize the audible prompt or voice command or alert signal.
Optionally, the driver prompt or alert may be provided via an audio signal or a tactile signal at the steering wheel or the like (such as a vibration of the steering wheel to alert the driver to view the display screen), and may be provided in addition to the automatic extension of the display screen or as a separate or secondary prompt. Such a secondary prompt may be particularly useful when the driver passes a waypoint or milestone in a journey. In such a situation, the display screen may already be extended to display the next waypoint/instructions, so the secondary prompt may alert the driver to check or view the display screen to notify the driver that he or she has passed the waypoint. Also, such a secondary prompt or audio or tactile signal may be particularly useful when the display screen is already extended for one function or system and another dynamic activating or triggering event occurs that has a higher priority than the first function or system. Because the display screen is already extended, the driver may not be prompted by the extension of the screen to view the new information. Therefore, the secondary prompt or signal may be provided to alert the driver to again look at the display screen. For example, if the driver or occupant of the vehicle is using a telephone system and the display screen is already extended to show telephone numbers or the like as the vehicle approaches a waypoint, the display screen may be adjusted or reconfigured to display the next set of instructions and/or compass heading and/or map associated with the approaching waypoint and the secondary prompt may be provided to alert the driver to look at the display screen. It is further envisioned that the display of the navigation instructions may be provided on the screen in addition to the telephone numbers (or other information or video being displayed on the display screen), such as in a picture-in-picture type format (such as is known in the television art) or the like. Optionally, the secondary prompt may only be provided in such situations where the display screen is already extended for a first activating event when a second activating event occurs.
Optionally, the navigation system and display screen may be provided as a self contained module or the like at the windshield area of the vehicle. For example, the navigation system, including the global positioning system antenna and control circuitry and the like, may be provided with a windshield electronics module or accessory module or the like or with the mirror assembly or overhead console, and may be in electrical connection or communication with the display screen device, such as via a wire connection or a wireless communication or the like. The complete navigation system and display thus may lend itself to aftermarket applications and may be installed in an existing vehicle.
For example, a stand alone navigation system may include a slide out or extendable/retractable display screen and a windshield electronics module. The windshield electronics module may include the antenna (such as a global positioning system antenna), controls and circuitry for the navigation system. The controls may be operable to receive manual inputs to set a desired route and may be operable to control or extend/retract the display screen and to activate the display screen to display the appropriate information to the driver, based on or in response to the geographical location of the vehicle along the selected or desired route, such as described above. The stand alone navigation system may include a user interface device, such as a keypad or manual inputs or the like, and one or more displays, such as icons, letters, characters, and/or indicia or the like. The user interface device may receive manual inputs that select the desired route (such as by entering a desired destination or address or the like), and the navigation system may determine the appropriate route and the appropriate waypoints at which the display screen may extend and activate to display the appropriate information to the driver of the vehicle.
Optionally, the user interface device may comprise a menu driven device that may display a plurality of functions in response to particular entries or key selections or inputs by the user of the navigation system. For example, the user interface device may include a display screen (and may be at or incorporated into the extendable/retractable display screen) and may include a plurality of inputs or buttons or sensors or the like positioned at or around the display screen. Optionally, the inputs may be positioned at and at least partially around the rim of the mirror, and the display may be provided as a display on demand transflective display at the mirror reflective element, such as a display of the types described in U.S. Pat. Nos. 5,668,663 and/or 5,724,187, and/or in U.S. patent application Ser. No. 10/054,633, filed Jan. 22, 2002 by Lynam et al. for VEHICULAR LIGHTING SYSTEM (Attorney Docket DON01 P-962); and/or Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), and/or PCT Application No. PCT/US03/29776, filed Sep. 9, 2003 by Donnelly Corp. et al. for MIRROR REFLECTIVE ELEMENT ASSEMBLY (Attorney Docket DON01 FP-1109(PCT)), which are all hereby incorporated herein by reference. Optionally, the inputs may be positioned around the rim of the display screen and the display on demand transflective displays may be provided at the display screen.
The inputs may be actuated to select particular functions displayed on the screen or may be held in or continuously or repeatedly actuated to scroll through functions or selections displayed on the screen. For example, the destination or address may be keyed into the navigation system by selecting and actuating an input that corresponds to the “destination entry” function shown on the display, where the user may then be prompted to key in the address or street name. The user then may actuate a first input and may continue to actuate the input (such as repeatedly actuating the input or holding the input down to continuously actuate the input) to scroll through the alphabet (such as with the scrolling letter being shown on the display on demand transflective display at the display screen or mirror reflective element) to set the first letter of the street name. Once the first letter is set, the user may do the same with a second input or button or sensor to set the second letter of the street name and so on. After a sufficient amount of letters have been selected (such as the first three or four letters of the street name), the display screen may display multiple street names in the targeted area (which may be input at the onset of the programming of the navigation system) that start with the same letters keyed in by the user. The user then may actuate another input to scroll through the listed street names to find and select the desired street name. For example, the user may key in the first letter, such as “M” for Maple Street by holding down the first button or input until “M” is shown at the first space of the street name. The second letter “a” may be selected in a similar manner. After the first few letters are entered, the user may then scroll through the list of street names that begin, for example, with the letters “M-a-p”, and may then scroll down until Maple Street is located, whereby the user may select “Maple Street” to enter the destination. The address and/or city and/or region and/or the like may be entered in a similar manner to input the destination for the vehicle. The navigation system may then program or select the appropriate route and may begin to extend the display screen and activate the display screen to provide the appropriate instructions and/or compass headings and/or maps to the driver of the vehicle as the vehicle travels along the programmed route and approaches the waypoints.
The display screen of the present invention thus may be operable in conjunction with one or more systems of the mirror assembly or accessory module or console or of the vehicle, and may be linked to such systems to display information or video or the like pertaining to the particular system when that system is activated or selected. The display screen may automatically extend and activate to display such information or video when a particular system is activated, or when a particular condition or location of the vehicle is detected, and may automatically retract when the particular system is deactivated or when the particular condition or location of the vehicle is passed. The display screen thus may extend to alert the driver that there is pertinent information or video being displayed at the display screen, and may be retracted when such information or video is not necessary or desired. The driver may override the display screen function to manually retract/deactivate the display screen when it is not desired, or to manually extend/activate the display screen when it is desired. The display system thus provides a dynamic extension system that responds dynamically to driving conditions and/or traffic conditions and/or vehicle conditions and/or hazardous conditions and/or selected systems or accessories.
Optionally, the video display screen device of the present invention may comprise a video display screen module, which may include the video display screen and the control and/or associated circuitry on the frame or support, such that the module is extendable and retractable relative to the mirror casing. Such a video display screen module may be purchased from a video display screen module source or supplier and assembled or installed into the mirror product at the mirror assembly plant. For example, the module may be slidably installed as a single unit on or along one or more slide members at the mirror casing and electrically connected to a lead or wire or connector at the mirror assembly, thereby easing the manufacturing processes of the mirror assembly and video display screen assembly. Although the addition of the control and associated components and circuitry to the extendable frame may add weight to the extended portion of the video display screen module, this is of minimal concern since any additional vibration of the mirror assembly which may occur due to the additional weight extended outward from the mirror casing may occur when the video display screen is in its extended position, which, as discussed above, is preferably occasional or temporary, and typically when the video display screen is in use.
It is further envisioned that the frame of the video display screen device of the present invention may support or include or contain one or more other accessories or controls. For example, one or more user actuatable controls or buttons may be included on the frame and may be operable to actuate or control the video display screen and/or one or more other accessories, such as a rearward viewing device or system, a cabin viewing device or system or a video communication device or system, or other accessories of the mirror assembly or of an accessory module or of the vehicle. Optionally, the frame may include or support other accessories, such as one or more microphones or speakers or the like, which may be associated with a video communication device or system in communication with the video display screen or may be associated with other audio devices or systems of the vehicle. Optionally, the frame may support or include a camera or video or imaging device or sensor, which may be directable toward the driver of the vehicle when the frame is extended toward the driver side of the vehicle. For example, the camera, video display screen and a microphone or microphones may all be included on the support frame of the video display screen device and may function in connection with a video and audio communication device or system or the like, such as a system utilizing principles disclosed in U.S. Pat. Nos. 6,243,003; 6,278,377; and/or 6,420,975; and/or PCT Application No. PCT/US03/30877, filed Oct. 1, 2003 (Attorney Docket DON01 FP-1111(PCT)), which are hereby incorporated herein by reference. Other controls and/or accessories, such as discussed below with respect to the mirror assembly, may also or otherwise be included in or incorporated into the frame of the video display screen device, without affecting the scope of the present invention.
Although shown and described as being positioned on a driver side of the mirror assembly when the mirror assembly is installed in a vehicle, a video display screen device in accordance with the present invention may alternately or additionally or preferably be positioned on the passenger side of the mirror assembly to provide an extendable and retractable video display screen for viewing by a passenger of the vehicle, without affecting the scope of the present invention. Because the mirror assembly is typically angled toward the driver of the vehicle to provide the driver with the appropriate or desired rearward field of view, the driver side video display screen device of the present invention may, in its extended position, interfere with or contact the windshield when the mirror assembly is angled toward the driver. In such applications where there may be insufficient clearance on the driver's side, it is desirable and preferable to have the video display screen slide outward toward the passenger side of the vehicle (as shown in
Interior rearview mirror assembly 10 includes a mounting portion 36 (
Interior rearview mirror assembly 10 may include bezel portion 14 and casing 12, such as described above, or the mirror assembly may comprise other types of casings or bezel portions or the like, such as described in U.S. Pat.

Optionally, the mirror assembly may comprise an electro-optic or electrochromic mirror assembly and may include an electro-optic or electrochromic reflective element. The electrochromic mirror element of the electrochromic mirror assembly may utilize the principles disclosed in commonly assigned U.S. Pat. Nos. 5,140,455; 5,151,816; 6,178,034; 6,154,306; 6,002,544; 5,567,360; 5,525,264; 5,610,756; 5,406,414; 5,253,109; 5,076,673; 5,073,012; 5,117,346; 5,724,187; 5,668,663; 5,910,854; 5,142,407 and/or 4,712,879, which are hereby incorporated herein by reference, and/or as disclosed in the following publications: N.

The thicknesses and materials of the coatings on the substrates, such as on the third surface of the reflective element assembly, may be selected to provide a desired color or tint to the mirror reflective element, such as a blue colored reflector, such as is known in the art and such as described in U.S. Pat. Nos. 5,910,854 and 6,420,036, and in PCT Application No. PCT/US03/29776, filed Sep. 9, 2003 by Donnelly Corp. et al. for MIRROR REFLECTIVE ELEMENT ASSEMBLY (Attorney Docket DON01 FP-1109(PCT)), which are all hereby incorporated herein by reference.
Optionally, and with reference to
Optionally, and desirably, the user inputs 15 may comprise one or more touch sensitive elements or touch sensors or proximity sensors positioned along the plastic mirror portion, such as the plastic casing or plastic bezel portion of the mirror assembly. The touch sensors or proximity sensors may be molded into the plastic mirror portion when the plastic mirror portion is formed or may be positioned in pockets within the plastic casing or plastic bezel portion, such that touching or approaching the plastic mirror portion with a finger or the like in the region where the touch sensor is positioned will actuate the touch sensor to provide the desired control function. The touch sensor thus may provide control or adjustment of one or more accessories, without the mechanical components and costs associated with known mechanical buttons and switches and the like. The touch sensors may be associated with or electrically connected to circuitry or a printed circuit board of the mirror assembly or of the vehicle or of an accessory module or console or the like of the vehicle or mirror assembly, whereby actuation of the touch sensor or sensors causes a corresponding activation or deactivation or adjustment or control of a desired or associated accessory or function, as also discussed below.
The touch sensitive elements or touch sensors or proximity sensors may utilize aspects of touch sensitive elements of the types described in U.S. Pat. Nos. 6,001,486; 6,310,611; 6,320,282; and 6,627,918, and U.S. patent application Ser. No. 09/817,874, filed Mar. 26, 2001 by Quist et al. for INTERACTIVE AUTOMOTIVE REARVISION SYSTEM (Attorney Docket DON01 P-889), which are hereby incorporated herein by reference. For example, the proximity sensor may comprise a capacitive proximity sensor that is operable to detect a capacitive disturbance or electric field detection or disturbance at or near the sensor when an object, such as a person's finger or the like, enters the electric field at the sensor. The proximity sensor may detect such a presence without requiring actual contact with the person's finger, and may detect the presence of the person's finger when the person's finger is within a few milimeters of the sensor, such as within approximately 3 mm or about 1 mm or closer. Optionally, the touch sensitive element may comprise a sensor of the types commercially available from TouchSensor Technologies, LLC of Wheaton, Ill. For example, the sensor may be operable to generate an electric field and to detect the presence of a conductive mass entering the field. When a voltage is applied to the sensor, the sensor generates the electric field, which emanates through any dielectric material, such as glass or plastic or the like (such as through the plastic bezel portion or the plastic casing of the mirror assembly or through the reflective element), at the sensor. When a conductive mass (such as a person's finger or the like, or metal or the like) enters the electric field, the sensor may detect a change in the field and may indicate such a detection.
The sensor may be implemented at the mirror assembly without requiring any new interface designs and with no need for electronic modification of a mirror assembly designed for conventional electromechanical buttons or switches. Because the touch sensitive elements or sensors have no moving parts to wear out, such touch sensitive elements may provide enhanced durability and longer life cycles over conventional mechanical switches.
As shown in
Likewise, in order to provide feedback to the user to indicate that the user successfully actuated the touch sensor or proximity sensor, it is envisioned that an illumination source, such as a light emitting diode (LED) or the like, may be positioned at or adjacent to a respective touch sensor, and may be energized or may glow when the touch sensor is actuated. The illumination source may be molded into the plastic mirror portion (such as the plastic bezel portion or the plastic casing at which the touch sensor is positioned) or may be embedded or positioned in a pocket formed in the plastic mirror portion. The plastic mirror portion may have a thin plastic wall at the region of the illumination source, such that the glowing illumination source may be visible through the thin plastic wall when the touch sensor is successfully actuated.
Optionally, one or more touch sensors or proximity sensors may be positioned along the bezel portion of the mirror assembly, and the mirror assembly may include one or more displays 15a, such as display on demand transflective type of displays, at the reflective element generally at or near or above the touch sensors. The display or displays may be operable to display an icon or character or text or indicia or the like that is associated with the function of the respective touch sensor when the touch sensor is actuated. The display thus may provide an indication of the function of the touch sensor and/or may provide an indication that the user successfully actuated the touch sensor. For example, if a touch sensor functions to activate and deactivate an accessory, such as, for example, a passenger side inflatable restraint (PSIR), an icon such as “PSIR on” may be energized or backlit or the like when the touch sensor is actuated to indicate that the PSIR is activated, and an icon such as “PSIR off” may be energized or backlit or the like when the touch sensor is actuated a second time to indicate that the PSIR is deactivated. The display icons or indicia may be energized or backlit for a period of time following the actuation of the touch sensor and then may be deactivated. If the touch sensors provide a specific function or control, the plastic mirror portion may have an icon or indicia or the like printed thereon that corresponds to the function of the respective touch sensor, and the display may then be activated to provide confirmation of a successful actuation of the touch sensor.
Optionally, and desirably, multiple touch sensors or proximity sensors may be positioned along the bezel portion of the mirror assembly, and the mirror assembly may include one or more displays, such as display on demand transflective types of displays, at the reflective element generally at or near or above the touch sensors (or elsewhere at the reflective element). The touch sensors may control one or more accessories or functions and the function of the touch sensors may change in response to user selections based on a menu driven display. For example, the display or displays may initially be operable to display icons or characters or text or indicia that are associated with initial or selected functions of the touch sensors, and then may be operable to display a second level or set of icons or characters or text or indicia that are associated with a selected second level or set of functions of the touch sensors. The mirror assembly thus may provide a menu driven control system, whereby the function or functions of the touch sensors may change or may be reconfigured depending on what initial function is selected or is displayed on the reflective element.
For example, the touch sensors may initially correspond to a particular or respective accessory or control function and a user may fist actuate one of the touch sensors to cause a display to show a selectable function or functions associated with the particular accessory, such as multiple functions pertaining to the particular accessory. For example, one of the touch sensors may be actuatable to control or adjust a compass system and display, whereby the display may show functions or controls for the compass system at respective ones of the touch sensors, such as “on” at one of the touch sensors, “off” at another one of the touch sensors, “cal” at another touch sensor (for calibrating the compass system or manually activating a calibration mode of the compass system), “zone” at another touch sensor (for changing the zone of the compass system), and/or the like. After touching the “compass” touch sensor to actuate the compass menu, the user may then actuate an appropriate touch sensor associated with the desired function. The user actuatable control or input thus provides two or more levels of controls, where the first level (or first actuation of one of the touch sensors) causes the display to show the second level of associated control functions and causes the function of the touch sensors to change corresponding to what is displayed at the reflective element. The touch sensors may then toggle the desired function or may adjust the desired function or may select a third level of menus or functions for the touch sensors to control or adjust.
Optionally, an initial actuation of any one of the touch sensors or proximity sensors causes the display to display or indicate the initial or default function of the touch sensors, such as “compass”, “temperature”, “PSIR”, “clock”, “lights”, and/or the like for the user to select to switch the display and touch sensors to the desired control level. For example, a user may initially actuate any of the touch sensors to view a display of their initial or default functions and then may selectably actuate the touch sensor at the “lights” icon, whereby the display may display different lights to activate/deactivate, such as, for example, “map” (for activating/deactivating map reading lights of the mirror assembly or of an accessory console or overhead system or console or of the vehicle), “ceiling” or “console” (for activating/deactivating ceiling lights of the vehicle or of an accessory console or overhead system or console), “rear seat” (for activating/deactivating lights that illuminate the rear seat of the vehicle, such as for a baby view camera or the like, such as described in U.S. Pat. No. 5,877,897 and/or U.S. patent application Ser. No. 09/793,002, filed Feb. 26, 2001, entitled VIDEO MIRROR SYSTEMS INCORPORATING AN ACCESSORY MODULE (Attorney Docket DON01 P-869), which are hereby incorporated herein by reference), “door” (for activating/deactivating lights in the vehicle doors), and/or other lights of the mirror assembly or an accessory module or an accessory console or overhead system or console or of the vehicle.
Optionally, the intensity or brightness of the display or displays may be automatically adjusted in response to an ambient light sensor or glare detector, such as a sensor of the interior rearview mirror assembly or vehicle or of a console or module or the like, such as the types disclosed in U.S. Pat. Nos. 4,793,690 and/or 5,193,029, which are hereby incorporated herein by reference, without affecting the scope of the present invention. In applications where the mirror reflective element assembly comprises an electro-optic or electrochromic mirror reflective element assembly, the displays may be automatically adjusted in response to the ambient light sensor or glare detector associated with the electro-optic or electrochromic circuitry or system. The display intensity of the displays may be adjusted in response to the photo sensor or light sensor, and may be increased during daytime lighting conditions and reduced at dusk or during nighttime lighting conditions. The intensity of the displays may be substantially continuously adjusted or may be adjusted in steps in response to the light sensor or sensors, such as by utilizing aspects of the displays described in U.S. Pat. Nos. 5,416,313 and 5,285,060, which are hereby incorporated herein by reference, or may be adjusted when the touch sensors are actuated.
Although shown and described as being positioned at the bezel or casing portion of the mirror assembly, it is envisioned that the touch sensors or proximity sensors or elements may be positioned elsewhere at or on the mirror assembly and may be positioned at the reflective element of the mirror assembly, such as behind the reflective element (where the presence of a person's finger at or near the reflective element may actuate the touch sensor or proximity sensor), without affecting the scope of the present invention. The reflective element assembly may comprises a display on demand transflective display and may include such proximity sensors to function as a touch screen (or proximity screen) for selecting or inputting the desired functions or inputs. It is also envisioned that the touch sensors or proximity sensors and displays of the types described above may optionally be provided at the display screen device of the present invention, such as at or within the frame of the display screen device or behind the display screen such that the display screen may provide a touch screen to provide menu driven controls or selections, or the touch sensors may be provided at an overhead console or accessory system or module or the like (such as at the overhead accessory system or module discussed below), without affecting the scope of the present invention. Also, although described as capacitive or electric field disturbance sensors that are actuatable by the user touching or approaching the plastic mirror portion or the reflective element or other mirror portion or module portion at the region corresponding to the touch sensor, it is envisioned that the proximity sensors or elements may comprise other touchless sensors or elements, such as antennae or antenna segments or the like that detect the presence of a person's finger at or near the region corresponding to the antenna segments, such as described in U.S. provisional application Ser. No. 60/508,086, filed Oct. 2, 2003 by Schofield for MIRROR REFLECTIVE ELEMENT ASSEMBLY INCLUDING ELECTRONIC COMPONENT (Attorney Docket DON01 P-1113), which is hereby incorporated herein by reference.
Optionally, the mirror assembly may include one or more other accessories at or within the mirror casing, such as one or more electrical or electronic devices or accessories, such as antennas, including global positioning system (GPS) or cellular phone antennas, such as disclosed in U.S. Pat. No. 5,971,552, a communication module, such as disclosed in U.S. Pat. No. 5,798,688, a blind spot detection system, such as disclosed in U.S. Pat. Nos. 5,929,786 and/or 5,786,772, transmitters and/or receivers, such as a garage door opener or the like, a digital network, such as described in U.S. Pat. No. 5,798,575, a high/low headlamp controller, such as disclosed in U.S. Pat. Nos. 5,796,094 and/or 5,715,093, a memory mirror system, such as disclosed in U.S. Pat. No. 5,796,176, a hands-free phone attachment, a video device for internal cabin surveillance and/or video telephone function, such as disclosed in U.S. Pat. Nos. 5,760,962 and/or 5,877,897, a remote keyless entry receiver, lights, such as map reading lights or one or more other lights or illumination sources, such as disclosed in U.S. Pat. Nos. 5,938,321; 5,813,745; 5,820,245; 5,673,994; 5,649,756; 5,178,448; 5,671,996; 4,646,210; 4,733,336; 4,807,096; 6,042,253; and/or 5,669,698, and/or U.S. patent application Ser. No. 10/054,633, filed Jan. 22, 2002 by Lynam et al. for VEHICULAR LIGHTING SYSTEM (Attorney Docket DON01 P-962); and/or Ser. No. 09/793,002, filed Feb. 26, 2001 (Attorney Docket DON01 P-869), microphones, such as disclosed in U.S. Pat. Nos. 6,243,003; 6,278,377; and/or 6,420,975; and/or PCT Application No. PCT/US03/30877, filed Oct. 1, 2003 (Attorney Docket DON01 FP-1111(PCT), speakers, a compass, such as disclosed in U.S. Pat. Nos. 5,924,212; 4,862,594; 4,937,945; 5,131,154; 5,255,442; and/or 5,632,092, a tire pressure monitoring system, such as the types disclosed in U.S. Pat. Nos. 6,294,989; 6,445,287; and/or 6,472,979, a seat occupancy detector, a trip computer, an ONSTAR® system and/or the like (with all of the above-referenced patents and patent applications being commonly assigned to Donnelly Corporation, and with the disclosures of the referenced patents and patent applications being hereby incorporated herein by reference in their entireties). The accessory or accessories may be positioned at or within the mirror casing and may be included on or integrated in a printed circuit board 38 (
Therefore, the present invention provides a mirror assembly that includes a video display screen which is laterally extendable from a side of a mirror casing for viewing by an occupant of a vehicle. The video display screen may be selectably or automatically sidably movable via one or more rails or slide members laterally within the mirror casing. The video display screen may be positioned substantially within the mirror casing when not in use, and may extend substantially outward from the mirror casing toward the driver or passenger side of the vehicle when viewing of the video display screen is desired. By having extension of the video display screen occurring occasionally and in response to one or more activating events or stimuli, such as discussed above, the temporary extension or presence of the video display screen, even when in or partially in the forward field of view of driver, is not unacceptable or hazardous. The extension and retraction mechanism allows for occasional use of the video display screen and allows the video display screen to be stowed when not in use. By slidably positioning the video display screen within the mirror casing, the present invention provides for a large video display screen to enhance viewing of the images displayed thereon by the driver or other occupant of the vehicle, while having a minimal affect on the size of the mirror casing. The mirror casing is formed to be wide enough to receive the video display screen therein, with the mirror casing being at least as wide as the height dimension of the video display screen. Although shown and described as being preferably incorporated into an interior rearview mirror assembly mounted at an interior surface of the windshield or alternatively at an interior rearview mirror assembly mounted at a header portion of the vehicle or the like, embodiments of the present invention may be of benefit and may be used in other regions of the vehicle, such as in windshield electronic modules or accessory modules or overhead systems or overhead consoles or the like, or into an instrument panel portion of the vehicle, or elsewhere in the vehicle, without affecting the scope of the present invention.
Referring now to
Overhead accessory system 50 may be suitable for a subsystem supplier or system integrator to provide the integrated overhead accessory system or module to the vehicle assembly line. The integrated overhead accessory system may thus provide substantial subsystems of the vehicle in a form that allows the vehicle assembler to readily install the subsystems as a single unit, thereby substantially reducing assembly and manufacturing processes for the vehicle assembly plant. The overhead accessory system may be shipped as a fully integrated unit, whereby the operator may make the mechanical attachments of the accessory module to the vehicle body and the minimum required electrical connections to connect electrical power and/or cables and/or the like (such as for communication with other controls or systems of the vehicle) to the accessory system. The electrical connections may be made to vehicle wiring harnesses or cables or systems or circuitry or controls the like, such as to vehicle electronic or communication systems and the like, and may be connected via various protocols or nodes, such as Bluetooth™, SCP, UBP, J1850, CAN J2284, Fire Wire 1394, MOST, LIN and/or the like, depending on the particular application of the overhead accessory system and the vehicle.

As can be seen with reference to
Because the rear cross car console or module 51c may include electronic accessories, such as a rear vision assist camera or lights or a center high mounted stop lamp or the like, and because the front console 51a may also include electronic accessories, the front and rear consoles (and middle console, if applicable) may be electrically interconnected, such that the electrical connection to the vehicle may be performed at only one location as the overhead accessory system is mounted to the vehicle. For example, the vehicle manufacturer may bring utilities or electrical connections through the front upper portion of the vehicle, whereby the front accessory console 51a may connect to the utilities or wires or cables or the like at the front of the vehicle cabin. If the overhead accessory system includes a middle console and/or rear console, which further includes an electronic accessory, such as a stop lamp or other light source or camera or the like, the overhead accessory system may have the appropriate connection for the electronic accessory of the middle console and/or rear console at the front console, such that a single electrical connection or connections may be made at the front console during installation of the overhead accessory system to minimize the electrical connections for the overhead accessory system during installation of the accessory system to the vehicle at the vehicle assembly plant. The overhead accessory system thus may provide an integrated accessory system which may provide electrical accessories at both the front and rear of the vehicle and may provide electrical connection to such accessories via a single electrical connection with the vehicle wiring or wire harness or controls or power source or the like. The present invention thus may be readily installed into the vehicle as an integrated unit to minimize the assembly processes at the vehicle assembly plant.
The multiple modules or consoles and bracing elements may be provided to the vehicle assembly plant as an assembled unit or may be provided as separate components. The operator or operators at the vehicle assembly plant may install the individual modules or consoles and then may install the connecting or bracing elements between the modules. In applications where the modules or consoles include electronic accessories, the bracing elements may include wiring and may electrically connect to each of the adjacent modules as the bracing elements are installed to the vehicle or mechanically attached to the modules. For example, the bracing members or elements and the modules may include corresponding electrical connectors, such as plug and socket type electrical connectors or snap together type electrical connectors, such that as the bracing members and/or the modules are installed, the electrical connection between the components are made.
The overhead accessory system 50 may be modified depending on the vehicle or desired application of the accessory system. For example, in some vehicles, only the front or header cross module 51a may be installed, while others may include a front console 51a and a rear console 51c, or a front console 51a and a middle console 51b, or a front console 51a, a middle console 51b and a rear console 51c, or only a middle or island console 51b, or only a rear console 51c, or any desired combination of consoles and connectors or bracing elements. For example, for a larger vehicle (such as a Suburban or other sport utility vehicle, van or like), the overhead accessory system may include three overhead accessory consoles (or more consoles if desired), such as shown in
The overhead accessory system may be mounted to the existing headliner or roof of the cabin of the vehicle or to a glass panel or glazing at the roof of the cabin of the vehicle. Optionally, the accessory system may include one or more glass panels or may include openings which correspond or generally align with glass panels or windows in the roof of the cabin of the vehicle.

Preferably, the connector 257 of the sub-module comprises a self-aligning connector to facilitate or enhance the connection to the connector 251b of console 251 (which may be a generally blind connection as the sub-module is inserted or plugged into the opening in the console). The connector 257 may “float” at the side of the sub-module housing 253 to further facilitate adjustment and alignment of connector 257 with connector 251b, such that connector 257 readily plugs into or receives or connects to connector 251b as the sub-module is inserted or plugged into the opening in the console. The sides of the housing 253 may assist in guiding the sub-module and electrical connector 257 into general alignment with the opening and electrical connector 251b, such that the sub-module may be readily inserted or plugged into the opening in the console by an operator at the vehicle assembly plant or the like, whereby the mechanical retention connection and electrical connection are made by the same installation or insertion process. Although shown as having the connector on the side of the sub-module, clearly, the electrical connector may be positioned elsewhere on the sub-module (and correspondingly on the console), such as at a bottom or back portion of the sub-module housing or elsewhere to provide electrical connection of the sub-module to the console as the sub-module is inserted or plugged into the opening in the console, without affecting the scope of the present invention.
As shown in the schematic of
In order to reduce the base cost and content of the overhead accessory system, the motherboard or wiring 260 of the accessory console 251 may provide only the base wiring (and optionally may only connect to power and ground at the vehicle wiring harness 270).
Also, the sub-modules 252, 254, 256, 258 may only include the electrical content for the particular accessory or system or feature provided by the sub-module (and may not include the interface circuitry or other intelligent circuitry or “smarts” for controlling and interfacing the accessories with the vehicle systems). Therefore, the motherboard 260 may include another electrical connector 264 for connecting to an enabler module 266 via an electrical connector 266a of enabler module 266. The enabler module 266 may be inserted into or plugged into the console at a desired location, such as at or adjacent to or near the sub-modules or elsewhere on the console.
Enabler module 266 may comprise a microprocessor with software and memory for interfacing with and controlling the accessories of the sub-modules and processing information or data received from the sub-modules (and optionally the interior rearview mirror assembly). The enabler module 266 may provide the interface circuitry and other smart circuitry, such as bus interface circuitry and the like, and may function to recognize what modules or sub-modules are connected to the motherboard 260, and may control or interface with the sub-modules to facilitate operation of the sub-module accessories. The enabler module 266 may control the signal flow to and from and between the sub-modules and the accessory system and/or the vehicle, and may manage a bus interface or the like between the sub-modules and the accessory system and/or the vehicle. The enabler module 266 thus enables the accessory system to work with whichever sub-modules are selected and plugged into the console 251, without requiring interfacing circuitry and the like in each of the sub-modules.
The enabler module 266 may provide other smart controls for the sub-modules so that the sub-modules need not include such additional and often costly circuitry, thereby reducing the incremental cost for each of the sub-modules added to the accessory system. The enabler module 266 thus functions to effectively transform the motherboard 260 into a “smart” motherboard that is capable of controlling and communicating with the sub-modules connected thereto, and that may let the vehicle know what information or circuitry or accessories that the vehicle has installed or available in the accessory system. Optionally, the enabler module may control one or more accessories of the motherboard, such as the lights 262 or the like. For example, the enabler module may receive a signal from a bus interface of the vehicle and may activate, dim and deactivate the lights of the accessory system in response to a signal indicative of situations where activation, dimming and deactivation of the cabin interior lights of the vehicle is desired, such as when a door is opened and closed or the like (without the enabler module, such lights may be activated by the user interface controls or buttons). Although shown and described above as being associated with a forward overhead accessory system, the sub-modules and enabler module of the present invention may be implemented at or in connection with the middle and/or rear accessory modules (such as the middle module 51b and rear module 51c discussed above), without affecting the scope of the present invention.
Optionally, the enabler module 266 may use or share circuitry from the various sub-modules plugged into the motherboard 260, and may be able to use or share such common or compatible circuitry from one sub-module for an accessory of another sub-module if there is a failure in the circuitry of the other sub-module. For example, the enabler module 266 may allow a telematics system of one sub-module (such as sub-module 252 in
Optionally, the enabler module circuitry may interface with other accessories of the vehicle (such as through a bus interface of the vehicle or the like, such as described in U.S. Pat. Nos. 6,291,905 and 6,472,773, which are hereby incorporated herein by reference) and may utilize circuitry or components of the other accessories in connection with the accessories of the sub-modules of the overhead accessory system. For example, the enabler module circuitry may facilitate the interface between the tire pressure monitoring system of sub-module 256 and the tire pressure sensors or the like at the tires of the vehicle, if applicable. Also, for example, the enabler module circuitry may utilize a sensor or camera for a vehicle vision system (such as a vision or camera system utilizing principles disclosed in U.S. Pat. Nos. 5,550,677; 5,760,962; 5,670,935; 6,201,642; 6,396,397; and/or 6,498,620, which are hereby incorporated herein by reference) of the vehicle for use with other accessories or systems (such as an automatic headlamp control system or rain sensor or the like) that are incorporated into one or more of the sub-modules of the overhead accessory system.
Optionally, the enabler module 266 may have reconfigurable aspects for reprogramming the microprocessor or for upgrading the software or the like. For example, the enabler module may be set up to recognize and receive new software or to recognize and interface with other accessories that may be developed and implemented after manufacture of the enabler module. The enabler module may receive a software upgrade via an input device, such as via an input port at the enabler module or elsewhere on the console, or via a DVD or CD player in the overhead console or in the vehicle, or via a diagnostic connection or interface of the vehicle, or via any other means of providing the upgrade to the overhead system and enabler module. Optionally, the enabler module may be removed and replaced with a new enabler module to accommodate other later developed software or accessories or features of the accessory system.
The enabler module 266 may be a common module regardless of which sub-modules are selected and connected to the accessory system. Therefore, the enabler module 266 may only be provided in situations where at least one sub-module having electronic accessories or circuitry is selected. The additional incremental cost for having more sub-modules is then lower because the smart circuitry and controls are already provided by the enabler module that is required for the first sub-module. If no electronic accessories or electronic sub-modules are selected, then no enabler module is required, whereby the openings in the console may be filled with various base-ine storage compartments or may be covered with a trim plate or the like. In such applications, the accessory system is substantially de-contented and only includes the motherboard or wiring and associated connectors and may be lights or the like.
Optionally, a standard accessory sub-module that is standard for a particular car line (for example, a vehicle may have a trip computer as a standard item, whereby a trip computer sub-module may be provided in all of the vehicles of that car line) may include the enabler circuitry, whereby the accessory system would not require or include a separate enabler module. In such an application, any additional or optional sub-modules may be provided without such smart or control or interface circuitry and may connect and communicate with and be controlled by the enabler circuitry of the standard accessory sub-module. Optionally, the consumer may select from several “base” options, where each of the options includes a particular accessory sub-module that incorporates the enabler circuitry, such that additional optional sub-modules need not require such circuitry.
The accessory system of the present invention thus provides for optional sub-modules that may be selected and plugged into a standard or common overhead console having a standard or common electronic motherboard. The smart circuitry and interface controls and circuitry and microprocessor may only be provided or added or connected to the console and motherboard (to make the motherboard function as a smart motherboard) if particular electronic accessory sub-modules are selected and plugged into the console. The present invention thus provides a distribution of the intelligence for controlling and interfacing such accessories or circuitry and may provide for interconnectivity of the modules or sub-modules and accessories or circuitry or systems of the overhead accessory system, and may provide such interconnectivity of the sub-module accessories or circuitry to other accessories or circuitry or systems of the vehicle. The accessory system may reduce or minimize the content of the individual sub-modules to reduce their incremental cost and to allow the vehicle manufacturer to only provide the typically costly interface circuitry, microprocessor and the like when it is needed and to only provide one module with such circuitry and the like, whereby the one module (either the enabler module or a standard sub-module or the like) may interface with and enable the other optional accessories or sub-modules that may be added to the accessory system. The accessory system thus may provide accessories that have a reduced incremental cost once a first accessory or sub-module is selected.

In the illustrated embodiment of
It is further envisioned that the modular console may comprise common modules or sub-modules that may be mountable in different vehicles or different vehicle lines, whereby the console and modules may be common across two or more vehicle lines, but the trim strips may be designed for adapting the outer trim of the console to a particular vehicle or vehicle line. As shown in
In each of the illustrated embodiments, the modular console may be formed or assembled using common accessory modules or sub-modules (containing various electrical or mechanical accessories or the like) to generally form the internal portion of the console, and then a particular trim portion may be attached to adapt the perimeter edges of the console for the particular vehicle or vehicle line that the module is to be installed into. As can be seen in
Therefore, the modular console or system of the present invention provides common accessory modules or storage modules or sub-modules or the like that may be assembled together to form the desired console. The common modules or sub-modules may be shipped to a vehicle assembly plant and assembled together in the plant to form the desired modular consoles for the particular vehicles or vehicle lines. The consoles may then be trimmed out or finished via a particular trim member or portion that fits along an exterior or perimeter portion of the console and that conforms to the interior portion of the particular vehicle or vehicle line.
The modular console of the present invention may be particularly suited for applications in vehicle assembly plants that assemble different or multiple car lines. In such applications, the common modules or sub-modules may be assembled to form the desired modular consoles (containing the selected options for particular vehicles) and the appropriate trim portion may be installed to accommodate the interior contours or the like of the particular vehicle or vehicle line, and then the desired modular consoles may be installed into the particular vehicle or vehicle line. Optionally, the connected modules may be installed into the vehicle before the trim portions are attached or installed, without affecting the scope of the present invention. The present invention thus reduces the number of different consoles that may be shipped to the vehicle assembly plant, since the desired console that has the various options selected for a particular vehicle may be assembled at the vehicle assembly plant using the common modules and the appropriate trim portions.

Optionally, the accessory module may incorporate or include user inputs or buttons or touch/proximity sensors to select/control the communication system or the like. The accessory module of the present invention thus may connect a cellular telephone or the like to a communication system, such that the accessory module may provide a hands-free communication system for the driver of the vehicle. The cellular telephone, which may be carried into the vehicle by a user, may be coupled to and provide two way communication with the vehicle-based or in-vehicle communication system, preferably wirelessly, such as via a Bluetooth™ protocol or similar short/restricted range radio frequency (RF) or infrared (IR) communication protocol.
As shown in
Although shown as being positioned along the interior surface of the windshield and below a headliner or console of the vehicle, it is envisioned that the accessory module of the present invention may be incorporated into an overhead accessory system of the types described above. For example, one of the compartments 60 or controls 62 of overhead accessory system 50, described above, may incorporate a receiving portion for receiving a cellular telephone in a similar manner as described above. The overhead accessory system may then include the circuitry and microphones and speakers to allow the telephone to be used as part of a hands free communication system.

Nos. 5,550,677; 5,670,935; 5,760,962; 5,786,772; 5,798,575; 5,914,815; 5,929,786; 5,949,331; 5,959,367; 6,175,164; 6,198,409; 6,201,642; 6,222,447; 6,396,397; and/or 6,498,620, and/or in commonly assigned U.S. patent application Ser. No. 09/199,907, filed Nov. 25, 1998, entitled WIDE ANGLE IMAGE CAPTURE SYSTEM FOR VEHICLES (Attorney Docket DON01 P-676); and/or Ser. No. 10/010,862, filed Dec. 6, 2001, entitled PLASTIC LENS SYSTEM FOR VEHICLE IMAGING SYSTEM (Attorney Docket DON01 P-954), which are all hereby incorporated herein by reference in their entireties, or such as a rear vision system and/or camera implemented and operated in connection with other vehicular systems as well, or operable utilizing the principles of such other vehicular systems, such as a vehicle headlamp control system, such as the type disclosed in U.S. Pat. No. 5,796,094, which is hereby incorporated herein by reference, a rain sensor, such as the types disclosed in commonly assigned U.S. Pat. Nos. 6,353,392; 6,313,454; and/or 6,320,176, which are hereby incorporated herein by reference, a traffic sign recognition system, a system for determining a distance to a leading vehicle or object, such as by utilizing the principles disclosed in U.S. Pat. No. 6,396,397, which is hereby incorporated herein by reference, or other vehicle vision systems and/or the like.
The rearward facing imaging system may include a rearward facing camera or imaging sensor 512, such as an imaging array sensor, such as a CMOS sensor or CCD sensor, such as described in commonly assigned U.S. Pat. Nos. 5,550,677; 6,097,023 and 5,796,094, which are hereby incorporated herein by reference, an extended dynamic range camera, such as the types disclosed in PCT Application No. PCT/US03/36177, filed Nov. 14, 2003 by Donnelly Corp. et al. for IMAGING SYSTEM FOR VEHICLE (Attorney Docket DON01 FP-1118(PCT)), which is hereby incorporated herein by reference, or any known camera or image sensor or the like. The camera 512 may be positioned at a rearward portion of the vehicle and directed generally rearwardly to capture an image of the exterior scene within the field of view of the camera. The camera 512 may communicate a signal representative of a frame or frames of the captured image of the exterior and rearward scene to a control or control system 514. The control may process the signal or signals received from the camera and communicate image data to the video screen or display of the display module or video screen module 510 for displaying an image representative of the rearward field of view of the camera at the video screen. The display module 510 may be configured to extend downwardly from the overhead accessory system (or may extend downwardly from the ceiling or headliner or other headliner console of the vehicle) to facilitate viewing of the video screen by the driver of the vehicle, such as when the vehicle is being driven in reverse, such as for parking, connecting the vehicle to a trailer or otherwise backing up the vehicle.
In one form, a video screen or display module may comprise a single video screen at the display module or video screen module. The display module may be configured to rotate approximately 180 degrees between a rearward or entertainment position, where the screen is directed generally rearwardly and is thus viewable by a passenger or passengers in the rear seats of the vehicle, and a forward or backup aid position, where the screen is directed generally forwardly and is thus viewable by the driver of the vehicle, either by turning around to directly view the screen or by viewing a reflection of the screen via the reflective element of the interior rearview mirror assembly. The display module may also be pivoted or flipped, such as about a generally horizontal pivot axis, between a raised or storage position at the ceiling of the vehicle cabin and a lowered or in use position for viewing by the driver or rear passengers of the vehicle. Optionally, the display module may be tilted or angled downward to adjust a viewing angle of the display, and may be capable of such tilting or angling or adjusting at any rotational position as it is pivoted or rotated between the rearward position and forward position. The display module thus may pivot about a pair of axes to provide adjustment of the display for enhanced viewing.
When in the rearward orientation, the video screen may display movies, games, television shows, videos and the like (such as via a feed or input from an antenna, DVD player, video player, game system and/or the like) to the rear passengers, while the video screen may display images of the rearward exterior scene (such as via a feed or input from the rearward imaging system) to the driver of the vehicle when in the forward facing orientation. Other feeds or inputs to the display module may be provided to display other images or information or the like at the screen of the display module, and may be selectably displayed at the screen, without affecting the scope of the present invention. Optionally, the display output of the video screen may be selectably controlled or adjusted, or may be automatically controlled in response to the orientation of the display module, without affecting the scope of the present invention. For example, the back up aid display function may be automatically selected in response to the display module being adjusted to the forward orientation. Therefore, the driver and the rear passengers of the vehicle may selectably utilize and view the video screen or display of the display module of the present invention.
In another form, and as shown in
Optionally, the driver of the vehicle may view the forward facing video screen 518 directly by turning and facing the screen, or the driver may view the forward facing video screen indirectly by viewing the screen's reflection at the reflective element of the interior rearview mirror assembly 520. It is further envisioned that the control 514 of the imaging system may adjust the display image according to the designed viewing approach for the driver, such as by providing a reverse image display for viewing at the reflective element of the interior rearview mirror assembly, such as by utilizing aspects of a reverse image information display of the type disclosed in U.S. Pat. No. 6,124,647, which is hereby incorporated herein by reference. The display image on the screen may thus be displayed as a reversed or mirrored image so that a reflected image of the reversed display image may be properly viewable and readable by the driver at the reflective element of the rearview mirror. It is further envisioned that the display image may be selectably adjusted depending on the viewing approach preferred by the driver of the vehicle, without affecting the scope of the present invention.
As can be seen with reference to
Therefore, a video screen or display module may be provided which is operable to selectably display entertainment images or the like to the rear passengers of the vehicle and rearward viewing images to the driver of the vehicle to assist the driver in driving the vehicle in reverse. The video screen module may comprise a single screen and may be flipped or rotated to adjust the screen between a rearward facing position for viewing by the rear passengers and a forward facing position for viewing by the driver. Optionally, the video screen module may comprise dual video screens or displays, where one screen is directed generally rearwardly for viewing by the rear passengers, while the other screen is directed generally forwardly for viewing by the driver of the vehicle. The operation of the video screen or screens may be selectably controlled by the driver or passenger of the vehicle or may be automatically controlled, such as in response to an orientation or adjustment of the display module or in response to the vehicle being shifted into reverse or the like.
Therefore, the present invention provides an overhead accessory system which may comprise a modular system which allows the vehicle manufacturer to customize the accessory system for the desired application or vehicle. The overhead accessory system may comprise a single forward cross car console or module, and/or may comprise a middle or center cross car console or module positioned generally at a middle portion of the vehicle, and/or may comprise a rear cross car console or module positioned toward a rear portion of the vehicle. The modular and integrated overhead accessory system allows the vehicle manufacturer to implement one or more of the modules or console, which may be connected together via longitudinal extending bracing portions or connectors (and may be electrically connected together via wires or cables or the like extending along the bracing portions), depending on the desired application and/or the length of the vehicle and/or the like. The integrated overhead accessory system of the present invention thus substantially reduces the manufacturing processes for connecting multiple accessories to the vehicle wiring because the multiple accessories of the overhead accessory system or module may be readily connected at one of the consoles or modules, while the accessory system provides electrical connection to the accessories or electrical components at the other consoles or modules of the accessory system. The overhead accessory system may be configured to receive selected ones of various sub-modules and may provide enabling circuitry or controls at a single module that is operable to interface with and control the accessories and/or circuitry of the sub-modules that are plugged into or connected to the accessory console. The accessory system thus may provide a common console and common enabling circuitry, whereby the sub-module or sub-modules having the desired accessories or circuitry may be plugged into the common console and recognized and controlled by the enabling circuitry.
The present invention also provides a display screen that is slidably or movably positioned at or within a casing and that may be extendable and operable in conjunction with one or more systems of the mirror assembly or accessory module or console or of the vehicle. The display screen may extend sidewardly or laterally toward the passenger side of the vehicle from the casing, such as a mirror casing or windshield electronics module casing or accessory module casing or the like. The display screen may be linked to such systems to extend and to display information or video or the like pertaining to the particular system when that system is activated or selected. The display screen may automatically extend and activate to display such information or video when a particular system is activated, or when a particular condition or location of the vehicle is detected, and may automatically retract when the particular system is deactivated or when the particular condition or location of the vehicle is cured or completed or passed. The display system thus provides a dynamic extension and/or retraction system that responds dynamically to driving conditions and/or traffic conditions and/or vehicle conditions and/or hazardous conditions and/or selected systems or accessories, and that may extend to alert the driver that there is pertinent information or video being displayed at the display screen, and retract when such information or video is not necessary or desired.
Changes and modifications in the specifically described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims as interpreted according to the principles of patent law.
