Description




TECHNICAL FIELD




The present invention relates generally to display monitors for passenger vehicles, and more particularly to a display monitor system with a monitor that is automatically deployed or stowed upon the occurrence of a predetermined status change within a vehicle.




BACKGROUND




Display monitors systems have become popular accessories in passenger vehicles, and find a wide variety of applications in various vehicular systems. For example, a display monitor system may be used in a vehicle as a computer monitor, a navigation display, a closed-caption display for an external camera, etc. Flat panel display (FPD) monitor systems have become particularly popular in vehicular entertainment systems for such uses as a television, video game monitor or video cassette player monitor.




A display monitor system may be mounted in a variety of locations within a passenger compartment of a vehicle, depending upon the type of vehicle and the intended use of the system. For example, in a passenger automobile, a display monitor system for use as a rear seat passenger entertainment system display may be mounted to the ceiling of the passenger compartment of the vehicle at a location between the front and rear seats so that it is viewable by rear seat passengers.




Ceiling-mounted display monitor systems typically include a monitor that extends into the passenger compartment of a vehicle, often from a central region of the vehicle ceiling. Unfortunately, ceiling-mounted display monitor systems may potentially interfere with the ordinary use of the vehicle. For example, the monitor may partially obscure a driver's rearward view when the driver is operating the vehicle in reverse. Similarly, the monitor may be a hindrance for a passenger getting into or out of the rear seat of the vehicle. For this reason, many display monitor systems include a monitor that is movable between a deployed position, in which the monitor is positioned for viewing by a vehicle occupant, and a stowed position, in which the monitor is positioned to lessen interference with the ordinary use of the vehicle.




Although stowable monitors offer safety benefits over fixed-position monitors, occupants of the vehicle may sometimes find stowing the monitor to be an inconvenience. For example, a driver wanting to use the automobile in reverse may need to get into the passenger compartment of the automobile to stow the monitor before backing up. Also, vehicle occupants may forget or neglect to stow the monitor when the automobile is not in use, which may make the monitor more susceptible to damage while performing activities such as loading or unloading a vehicle. Furthermore, it may be inconvenient for passengers getting into the automobile to first reach in and stow the monitor. In each of these situations, vehicle users may neglect to stow the monitor and thus not realize the safety benefits provided by the stowability. Therefore, it would be desirable to have a display monitor system with a stowable monitor that provides for the improved safety and convenience of vehicle occupants.




SUMMARY OF THE INVENTION




The present invention provides a display monitor system for mounting in an automobile, the automobile having an interior and a vehicle status indicator with a changeable state that. The display monitor system comprises a monitor, a motor drivingly coupled to the monitor, and a controller operatively connected to the motor for controlling the motor. The monitor has a viewing surface, and is configured to be movably coupled to the interior of the automobile such that the monitor is movable between a deployed position, in which the viewing surface is visible to the viewer, and a stowed position. The motor is drivingly coupled to the monitor to move the monitor between the stowed position and the deployed position. The controller is adapted to detect a change in the state of the vehicle status indicator and to signal the motor to move the monitor to a predetermined position corresponding to the detected change in the state. Alternatively, the controller may be adapted to itself detect a status of a vehicle component, and to move the monitor accordingly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention provides a vehicular display monitor system for a passenger vehicle in which a monitor is automatically deployed or stowed upon detecting certain predetermined status changes in a vehicle. A display monitor system according to the present invention is indicated generally at


10


in

FIGS. 1-3

.




System


10


includes a monitor


12


that is movably coupled to a base


14


. Base


14


is configured to be mountable to a vehicle


16


within the vehicle passenger compartment


18


. Monitor


12


is movably coupled to base


14


such that it may be moved between a deployed position (FIG.


3


), in which the monitor is viewable by vehicle passengers, and a stowed position (FIG.


2


), in which the monitor interferes less with the use of the vehicle by a vehicle occupant.




In the embodiment depicted in

FIG. 1

, display monitor system


10


is installed in a passenger vehicle


16


, which takes the form of a van. However, it will be appreciated that system


10


may be installed in any type of passenger vehicle including a car, truck, motor home, etc. Additionally, while system


10


is shown mounted to ceiling


20


of passenger compartment


18


, between driver's seat


22


and a first row of rear seats


24


for viewing by rear passengers, it will be understood that system


10


may be installed at any desired location in the passenger compartment for viewing by any or all of the occupants. It will also be understood that monitor


12


may be movably coupled directly to the vehicle ceiling without the use of base


14


.





FIGS. 2 and 3

depict display monitor system


10


in more detail. As these figures show, base


14


includes a bottom portion


30


, and a mechanical and electronics housing


32


extending upwardly from bottom portion


30


. Bottom portion


30


forms a lower surface of base


14


, and includes a plurality of mounting holes


34


adapted to receive fasteners for mounting base


14


to ceiling


20


. Any suitable fastening mechanism (e.g. screws) may be used to attach base


14


to ceiling


20


. Furthermore, base


14


may be attached to ceiling


20


with an adjustable method, such as that disclosed in U.S. patent application Ser. No. 09/626,210 for a VEHICLE DISPLAY MONITOR SYSTEM, filed on Jul. 26, 2000, which is hereby incorporated by reference.




Base


14


is generally designed to have a low profile in a vehicle so that the base interferes minimally with the actions of vehicle occupants in passenger compartment


18


. Base


14


, for example, may be configured to extend only partially, if at all, into passenger compartment


18


. In the depicted embodiment, base


14


is configured to fit substantially flush with a headliner (not shown) in the vehicle. In fact, bottom portion


30


of base


14


is configured to rest against the headliner adjacent a hole in the headliner through which monitor


12


extends when deployed. A covering or shroud (not shown) may be provided to cover any portion of base


14


that extends through the vehicle headliner, but is not necessary.




When in the stowed position, monitor


12


may nest partially or fully in a recess


36


formed in base


14


, as shown in FIG.


2


. Positioning monitor


12


in recess


36


when in the stowed position helps to reduce the intrusion of display monitor system


10


into passenger compartment


18


while in the stowed position, and also helps to protect monitor


12


from damage while stowed. In the depicted embodiment, monitor


12


is configured to retract fully into recess


36


when stowed, thus positioning monitor


12


flush with, or even recessed into, the vehicle headliner when stowed. However, monitor


12


may also retract only partially into base


14


when stowed, or may simply rest against base


14


(or the vehicle ceiling).




Monitor


12


may be any type of monitor known in the art for use in vehicles, and is typically a flat panel display (FPD) monitor. Monitor


12


includes a monitor housing


40


with a viewing surface


42


for displaying an image to a passenger.




As mentioned above, monitor


12


is movably coupled to base


14


so that it may be moved between a stowed position and a deployed position. Monitor


12


may be movably coupled to base


14


with any suitable mechanism. In the depicted embodiment, however, monitor


12


is pivotally coupled to base


14


so that it may be pivoted about an axis


38


between the stowed and deployed positions. Furthermore, monitor


12


may have a continuous range of possible deployed positions so that the angle of the monitor can be adjusted to suit passengers of different heights. While in the depicted embodiment monitor


12


is stowed with viewing surface


42


facing down into the vehicle passenger compartment, monitor


12


may also be stowed with the screen


40


facing up toward ceiling


20


of vehicle


16


, or in any other desired orientation.




In accordance with the present invention, monitor


12


is operatively connected to a driving mechanism for driving monitor


12


between the stowed and deployed positions.

FIG. 3

shows one embodiment of a suitable driving mechanism


60


for driving the monitor between positions. Driving mechanism


60


includes a motor


62


to power movement of the screen between positions. Any suitable motor may be used. Typically, motor


62


is an electric step motor, and is powered by the vehicle battery.




Motor


62


includes a drive shaft


64


, to which a drive shaft gear


66


is attached. Drive shaft gear


66


is engaged with an axle gear


68


, which is in turn coupled to an axle


70


that is fixed to monitor


12


. Thus, when motor


62


is operated, its motion is transferred to axle


70


and thus turns monitor


12


. Axle


70


is fixed to monitor


12


via any suitable cooperative mechanism, and can be fixed to monitor


12


at any suitable location on monitor


12


. In the depicted embodiment, axle


70


is fixed to monitor


12


adjacent the top edge of monitor


12


. Axle


70


is also coupled to base


14


to support monitor


12


on base


14


.




Motor


62


is in communication with a controller, shown schematically at


80


in

FIG. 3

, for controlling the movement of monitor


12


. Controller


80


may be configured to direct motor


62


to move monitor


12


upon receiving various selected inputs. For example, controller


80


may be in communication with a user-controllable external device, such as a control panel or remote control, to allow a user to deploy, stow or adjust the position of monitor


12


manually. Furthermore, controller


80


is adapted to detect changes in the status of the vehicle, or various vehicle components. Accordingly, when a predetermined change in the status of the vehicle, or of a particular component of the vehicle, is detected, the monitor may be moved to a correspondingly desired position to reduce interference with an occupant's use of the vehicle.




One vehicle component that may be monitored for status changes is a vehicle door. Each door in the vehicle has an open status and a closed status. Typically, the vehicle will have a corresponding status indicator that detects the status of the door and indicates the status with a suitable mechanism, such as a dashboard light. Depending upon the location of display monitor system


10


in the vehicle, monitor


12


may interfere with passengers entering or exiting the vehicle through various doors in the vehicle when in the deployed position. To compensate for this, controller


80


may be configured to detect a change in the status of one or more vehicle doors adjacent display monitor system


10


from closed to open in any suitable manner, such as by detecting the status indicator, and when such a status change is detected, to move screen


12


to a less obstructive position (e.g. the stowed position).




Another vehicle component that may be monitored for status changes is the automobile transmission. While driving in a forward gear, the driver of a vehicle with a passenger compartment-mounted display monitor will not ordinarily be distracted by the monitor, as the display monitor system will typically be mounted at a location behind the driver, and the monitor will not ordinarily block much of the view area of the rear view mirror. However, when a driver is operating the vehicle in reverse, the driver may wish to stow the monitor so as to further reduce obstruction of the drivers' rearward view. Thus, controller


80


could monitor the vehicle transmission for a change in the transmission status to a reverse gear (or “reverse gear status”). The controller typically monitors the transmission status by monitoring a suitable transmission status indicator. The vehicle may have one or more transmission status indicators. For example, the vehicle may have a dashboard light that indicates when the reverse gear is engaged, or may have backing lights that are illuminated only when the vehicle is in the reverse gear. Upon detecting a change to a reverse gear status, controller


80


may then direct motor


62


to move monitor


12


to the stowed position so that the driver's view out the rear of the vehicle is relatively unimpeded by monitor


12


while the car is in reverse.




Yet another vehicle component that could be monitored by controller


80


for a change in status is the vehicle ignition switch. This is because it is often desirable to stow monitor


12


while the car is not being used. First, monitor


12


is protected from damage from passengers entering or exiting the car, or from objects being put into or removed from the car, while in the stowed position. Second, the presence of monitor


12


in the passenger compartment may make the vehicle a more attractive target for thieves. When monitor


12


is stowed, it is less visible from outside the vehicle, and thus may reduce the susceptibility of the vehicle or display monitor system


10


to theft.




Generally the vehicle ignition switch will include an open switch status and a closed switch status, although many vehicles have ignition switches with multiple positions, such as an auxiliary position in which power is supplied to various vehicle systems while the motor is not running. The open switch status corresponds to the status wherein the car engine is turned off, and the closed switch status corresponds to the status wherein the car engine is powered. Typically, the vehicle will have a status indicator that indicates whether the ignition switch is in the open or closed position. Controller


80


may monitor the vehicle ignition switch, for example by monitoring the status indicator, for a change in status from the closed switch status to the open switch status. When this change in status is detected, controller


80


may move monitor


12


toward, or to, the stowed position so that the monitor is stowed when the vehicle is turned off.




In addition to moving monitor


12


to the stowed position upon detecting a predetermined change in vehicle status, controller


80


may also be configured to move monitor


12


back to its initial position (the position of monitor


12


immediately before it was moved to the stowed position), or to a default deployed position, upon detecting a converse predetermined change in the status of the component.




For example, once the door of the vehicle has been closed, the passenger most likely has finished entering or exiting the automobile, and thus the condition that gave rise to the need for stowing monitor


12


has passed. Similarly, once the car has been turned on or taken out of reverse, the conditions that gave rise to the need for stowing monitor


12


have also passed. Therefore, the controller may be configured to detect a change in the door status from open to closed, the ignition switch status from open to closed, or the transmission status from reverse gear to non-reverse gear, and to move monitor


12


back to the initial position upon detecting the change.




In order for the controller to be able to return monitor


12


to its initial position after detecting the converse predetermined change in status of a component, controller


12


must be able to detect the initial position before moving the monitor to the stowed position. To provide for this capability, display monitor system


10


includes an encoder


90


operatively coupled to monitor


12


to detect movement of monitor


12


and to encode the position of monitor


12


. Any suitable encoder for encoding rotational motion may be used. In the depicted embodiment, an optical encoder


90


is used. Optical encoder


90


encodes the position of monitor


12


by measuring light pulses generated by rotating a slotted wheel in front of a light source.





FIG. 4

illustrates the operative components of an exemplary optical encoder suitable for use with display monitor system


10


. Optical encoder


90


includes a light source


92


with a plurality of leads


94


for connecting light source to a power supply, and a detector


96


with a plurality of leads


98


for coupling detector


96


to controller


80


and to a power supply. Detector


96


is in optical alignment with source


92


so that detector


96


can detect light from source


92


. Optical encoder


90


also includes a wheel


100


with a plurality of light apertures


102


disposed between source


92


and detector


96


.




Wheel


100


is opaque so that it does not pass light from source


92


to detector


96


unless a slot is rotated between source


92


and detector


96


. Wheel


100


includes a shaft


104


coupled to monitor


12


so that wheel


100


is turned as monitor


12


is pivoted. Thus, as monitor


12


pivots, wheel


100


turns, causing light apertures


102


to pass sequentially between source


92


and detector


96


and pulses of light to reach detector


96


. Controller


80


may then count the number of pulses and detect the direction of motor rotation to determine the position of monitor


12


.




Controller


80


may be configured to detect the status of a desired vehicle component or components in any suitable fashion. As described above, in one embodiment of the invention, controller


80


is coupled to a vehicle status indicator to detect a change in status of a vehicle component. Many passenger vehicles are equipped with various vehicle status indicator circuits to indicate the status of vehicle components to the vehicle operator. For example, most passenger cars have indicator systems that warns a driver when a door is opened, when the ignition is turned off, or when the car is in reverse. These indicators generally operate by illuminating an indicator light on the vehicle dashboard, indicating a particular status condition. Furthermore, many cars have other systems that respond to changes in vehicle status, and thus also function as status indicators. For example, most automobiles have circuits that automatically illuminate backing lights when the automobile is put into reverse.




Each of these vehicle status indicators generally has at least two states: an indicator-active state and an indicator-inactive state. For example, when the vehicular component has a status such as a closed door status, an ignition switch closed status or a non-reverse gear status, the vehicle status indicator generally has an inactive state in which an indicator light is not illuminated or the backing lights are not illuminated. Likewise, when the component has the opposite status, such as an open door status, an ignition switch open status or a reverse gear status, the vehicle status indicator has an active state, in which the indicator light is illuminated or the backing lights are illuminated.




Controller


80


may take advantage of the presence of these existing vehicle status indicators by directly monitoring the state of the vehicle status indicator to detect changes in the status of the desired components.

FIG. 5

shows generally at


110


an electrical schematic diagram of a suitable monitor movement control system for detecting changes in the vehicle status indicator and moving monitor


12


when changes are detected. As shown in the figure, controller


80


has a power supply line


112


, one or more outputs to motor


62


, and a plurality of inputs for various motor control signals. In the depicted embodiment, controller


80


has two outputs


114


,


115


to motor


62


. Output


114


allows controller


80


to control the run/stop status of motor


62


, and output


115


allows controller


80


to control the direction in which motor


62


turns.




As shown in

FIG. 5

, controller


80


can have connections to a plurality of vehicle status indicators, if desired. In the depicted embodiment, controller


80


has a first connection


116


to an ignition status indicator


118


, a second connection


120


to a door status indicator


122


, and a third connection


124


to a transmission status indicator


126


. The status indicators are each depicted as a switch to reflect the two possible states of each indicator. However, it will be appreciated that a status indicator may also have more than two possible states, and the monitor may be moved between more than two positions without departing from the scope of the present invention.




Controller


80


also has an input from one of leads


98


coupled to encoder


90


. Input from lead


98


allows controller


80


to keep track of the pulses from encoder


90


to determine the magnitude of the movement of monitor


12


. The direction in which monitor


12


moves can be detected from other signals, such as the motor direction output


115


, or can be from encoder


90


itself, which may require a second input from encoder


90


. By receiving positional input from encoder


90


, controller


80


is able to track the position of monitor


12


.




Controller


80


includes memory


130


for storing the encoded position as an initial position so that monitor


12


can be moved back to the initial position when a corresponding change in the state of vehicle status indicator


118


,


122


or


126


is detected. Memory


130


may be any suitable type of memory. In one embodiment of the invention, memory


130


is a non-volatile memory, such as EPROM, EEPROM or flash memory, so that the initial position of monitor


12


will not be lost in case of a vehicular power failure or when the vehicle is turned off.




Controller


80


may have other inputs as well. For example, it may be desirable to include an input


132


from one or more limit switches


134


in display monitor system


10


to prevent damage to either monitor


12


or motor


62


caused by motor


62


attempting to over-rotate monitor


12


in either direction. Typically, two limit switches


134


are provided in display monitor system


10


; one to indicate a maximum deployed position, and the other to indicate the stowed position of monitor


12


. Other limit switches, such as a switch for a minimum deployed position, may also be provided if desired.




Controller


80


may also include an input


136


from an override control


138


. Override control


138


allows a user to disengage monitor


12


from motor


62


to allow the manual repositioning of monitor


12


. Override control


138


may provide for this capability in any suitable manner, such as by controlling the engagement or disengagement of a clutch mechanism (not shown) that couples monitor


12


to motor


62


. Alternatively, override control may be a manually operated mechanical clutch mechanism, and thus not include an input into controller


80


.




Controller


80


may also include an input


140


from a disable switch


142


. Disable switch


142


allows a user selectively to turn off or on the automatic stowing and deployment mechanism of the present invention. Disable switch


142


may allow a user to turn off the response of controller


80


to any or all of vehicle status indicators


118


,


122


and


126


. Furthermore, more than one disable switch may be provided to perform these functions without departing from the scope of the invention.





FIG. 6

shows generally at


200


an example of a methodology that provides for the automatic deployment or stowing of monitor


12


upon detecting a change in status of a vehicle component. While monitor


12


is in the initial position at


202


(typically a deployed position), controller


80


periodically reviews the status indicators for the door, the transmission and the ignition switch to detect a change to door open status, reverse gear status, or open ignition switch status (respectively) at


204


. Once a change in status is detected, controller


80


may then determine whether the monitor is within a predetermined positional range at


206


. The predetermined range may extend through the entire range of monitor positions, or may extend only through a more limited range of positions.




If the position of monitor


12


is within the positional range, then the monitor position is encoded by encoder


90


at


208


, the encoded position is stored in memory at


210


, and the monitor is moved to the desired position, such as the stowed position, at


212


. At this point, controller


80


then periodically reviews the status of the door, ignition switch and transmission to detect a change to closed door status, non-reverse gear status or closed ignition switch status at


214


. Once one of these status changes is detected, monitor


12


is then moved back to the encoded position at


216


, and controller


80


again periodically reviews the status of the vehicle components for the changes in status shown at


204


.




Alternatively, if monitor


12


is in a position outside of the predetermined positional range at


206


, then the position is not encoded or stored. Instead, the monitor is simply moved to the stowed position at


218


, and controller


80


then periodically reviews the status of the door, ignition switch and transmission to detect for changes in status to a closed door, closed switch or non-reverse status. When a converse change in status is detected, controller


80


then moves monitor


12


to a default position at


222


. The default position may be any desired position. Examples of possible default positions include a fully deployed position, a minimally deployed position, a halfway deployed position, or even the stowed position, in which case the monitor would remain stowed when the second change in status is detected.




It is to be appreciated that controller


80


need not have to determine whether monitor


12


is in an encodable range at


206


. Instead, the encodable range may extend through the entire movable range of monitor


12


, in which case all monitor positions would be in range and there may be no default position at all. Furthermore, the position of monitor


12


may not be encoded at all. In this case, monitor


12


may simply be left in the stowed position, or may always be moved to a default position, when a change to a closed door, closed switch or non-reverse status is detected.
