The present invention relates to vehicular vision systems that display video images derived from image data captured by one or more cameras of the vehicle.
It is known to provide a video display at an interior rearview mirror assembly to display sideward and/or rearward images, such as described in U.S. Pat. No. 5,670,935, which is hereby incorporated herein by reference in its entirety.
The present invention provides a vehicular vision system that displays video images at a video display screen, such as at an interior rearview mirror assembly or center console or stack, for a camera monitoring system using at least a rearward viewing camera disposed at the vehicle and having a field of view at least rearward of the vehicle. The rear camera is mounted at a camera mounting bracket that mounts to or attaches at a spare tire mounting bracket at the rear of the vehicle. The camera mounting bracket is adjustable to adjust a height of the rear camera to position the rear camera above a spare tire mounted at the spare tire mounting bracket. The camera mounting bracket may adjustably mount to the spare tire mounting bracket or may comprise at least one extendable/retractable arm that extends/retracts to adjust the height of the camera above the spare tire mounted at the spare tire mounting bracket.
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.
A vehicular camera monitoring system or display system operates to capture images exterior of the vehicle via at least a rearward viewing camera and may process the captured image data to display images and to detect objects at or near the vehicle and rearward of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The system includes an image processor or image processing system that is operable to receive image data from one or more cameras and to provide an output to one or more display devices for displaying video images representative of the captured image data. For example, the vision system may provide a rearview display or a top down or bird's eye or surround view display or the like.
The system provides an adjustable mounting configuration for the rearward viewing camera to accommodate use of the camera at a vehicle (such as a sport utility vehicle or the like) that has a removable top (such as, for example, a Jeep Wrangler or Ford Bronco or other vehicle that has a removable roof/top and/or is manufactured with different roof types). The rearward viewing camera is mounted at the rear portion of the vehicle (and not at the roof or top of the vehicle), such as at a spare tire mounting arrangement at the rear of the vehicle, and is adjustable to allow for adjusting the height and orientation of the camera for the particular vehicle and spare tire mounted at the spare tire mounting arrangement. By providing the rearward viewing camera at the spare tire mounting arrangement, such as at an arm that also supports a center high-mounted stop light (CHMSL), the vehicle user would not have to remove the camera or wiring when changing between a hard top configuration (where the hard top is on the vehicle), a soft top configuration (where a soft top is on the vehicle) and/or a no top configuration.
Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 includes a display or vision system 12 that includes a rearward viewing camera 14 for capturing image data for displaying at an interior display screen 22 that is viewable by the driver of the vehicle while operating the vehicle 10 (
The vision system 12 includes a control or electronic control unit (ECU) 18 having electronic circuitry and associated software, with the electronic circuitry including a data processor or image processor that is operable to process image data captured by the cameras, whereby the ECU 18 may detect or determine the presence of objects or the like and/or the ECU 18 may provide video images to a display device 16 of the interior rearview mirror assembly 20 (e.g., a video display screen disposed in the mirror head and behind and viewable through the mirror reflective element of the mirror head) of the vehicle for viewing by the driver of the vehicle and/or to a display device 22 at the center console or stack of the vehicle (and optionally to CMS displays at or near the driver and passenger side A-pillars of the vehicle, such as described in U.S. Publication Nos. US-2018-0134217 and/or US-2014-0285666, which are hereby incorporated herein by reference in their entireties). The data transfer or signal communication from the camera(s) 14 to the ECU 18 may comprise any suitable data or communication link, such as a vehicle network bus or CAN (Controller Area Network) bus or LIN (Local Interconnect Network) bus or I2C bus or the like of the equipped vehicle.
The ECU 18 receives image data captured by each of the cameras 14 and the image data is processed by the data processor or image processor of the ECU. The ECU 18 is connected to the video display 16 of the mirror assembly 20, such as via a single coaxial wire or cable for communicating with the video display 16 (such as to provide control signals or the like) and for providing video image signals to the video display 16, and/or the ECU 18 is connected to the display device 22 of the center console, such as via a single coaxial wire or cable for communicating with the display and for providing video image signals to the display. The system may utilize aspects of the systems described in U.S. patent application Ser. No. 17/248,736, filed Feb. 5, 2021 (Attorney Docket DON01 P4085), which is hereby incorporated herein by reference in its entirety.
For example, the ECU 18 may automatically adjust the output to the video display 16 and/or the display device 22 based on the driving conditions so that the appropriate video images are displayed by the video display 16 and/or the display device 22. In this example, when the vehicle is reversing or parking, the ECU 18 outputs the video image signals to the video display 16. When the vehicle is driving forward during normal driving conditions along a road, the ECU outputs the video image signals to the display device 22. In some implementations, the ECU outputs the video image signals to the video display 16 in the rearview mirror assembly 20 in response to a user input while the vehicle is driven forward along a road.
The interior mirror assembly may comprise a dual-mode interior rearview video mirror that can switch from a traditional reflection mode to a live-video display mode, such as is by utilizing aspects of the mirror assemblies and systems described in U.S. Pat. Nos. 10,442,360; 10,421,404; 10,166,924; 10,046,706 and/or 10,029,614, and/or U.S. Publication Nos. US-2020-0377022; US-2019-0258131; US-2019-0146297; US-2019-0118717; US-2019-0047475 and/or US-2017-0355312, and/or U.S. patent applications Ser. No. 16/949,976, filed Nov. 23, 2020 (Attorney Docket MAG04 P4024), and/or Ser. No. 17/247,127, filed Dec. 1, 2020 (Attorney Docket MAG04 P4043), which are all hereby incorporated herein by reference in their entireties. When in the live-video display mode, the video display screen 16 displays video images derived from video image data captured by the rearward viewing camera 14. The mirror may switch to the live-video display mode responsive to user actuation of a user input at the mirror assembly and while the vehicle 10 is being driven in the forward direction along a road (and optionally during a reversing maneuver of the vehicle 10 if the video images captured by the rear camera 14 are displayed at the display device 22 in the center stack and not at the video display 16 in the rearview mirror).
As shown in
The vision system 12 thus may display (e.g. via the video display 16 and/or the display device 22) video images derived from the rear camera 14, such as when the vehicle 10 is traveling forward and the rear display has been selected. The ECU 18 may receive two camera inputs, including a reverse aid input from a rear backup camera positioned at and viewing through the center of the spare tire 24 (for providing rear backup video images during a reversing maneuver of the vehicle 10), and a rear view input from the rear camera 14 located just above the CHMSL 26 (or at or near or adjacent to the CHMSL 26).
Typically, a vehicle 10 having a hard top/soft top option may have a CHMSL 26 fixedly mounted on a fixed bracket that is fixedly mounted at a rear portion or panel of the vehicle 10 behind the spare tire 24 (see
As shown in
Optionally, a supplemental or auxiliary illumination source 32 (such as a white light-emitting light emitting diode) may also be disposed at the crossbar element 28b. The auxiliary illumination source 32 may comprise a reverse light (that operates with the reversing lights at the taillights of the vehicle) or may comprise an auxiliary light to illuminate (such as with white light or with infrared or near infrared light) the area rearward of the vehicle 10 to enhance image capture by the rear camera 14 and/or the rear backup camera in low ambient lighting conditions.
The spare tire bracket 30 (
Optionally, the vertically oriented structural arms 28a of the camera mounting bracket 28 may comprise telescoping arms to allow for adjustment of the height of the crossbar element 28b without having to remove the spare tire 24. The telescoping arms may include a lower portion that is fastened or attached at the spare tire bracket 30 and an upper end that is adjustably disposed at the lower portion and that is selectively secured at a selected one of a plurality of positions or lengths to allow for positioning of the rear camera 14 at a selected or appropriate height above the spare tire 24. In some implementations, the rear camera 14 may be mounted on distal end of the upper end of the telescoping arms that allows the rear camera 14 to extend or retract relative to the lower portion. The telescoping arms may be secured in the selected length via a pin that extends through both the upper and lower portions (such as a spring-biased pin movably disposed at the inner one of the telescoping arms that is spring-biased or urged outward to engage or be received in one of a plurality of holes along the outer one of the arms), or via any other suitable means, such as a set screw that retains the telescoping arm portions at the selected location or via a clamping element that clamps the upper and lower telescoping arm portions at the selected location or the like.
Thus, the present invention provides a CHMSL and camera mount for a CMS rear camera 14 on a vehicle 10 with a removable or changeable top. In some implementations, instead of requiring a CHMSL bracket, the CHMSL is also attached to the mounting bracket 28. The CMS camera 14 is located at or next to the CHMSL (
