Abstract

A vehicular display system includes an electronic control unit (ECU), a plurality of bird's eye surround view cameras and a plurality of camera monitoring system (CMS) cameras disposed at the vehicle. The cameras capture image data and provide captured image data to the ECU. The system includes a video display screen and a video mirror display screen that are operable to display video images derived from video images provided by the ECU. When the vehicle is traveling forward at a speed below a threshold speed, the ECU generates rearward view video images derived from image data captured by the CMS cameras and provides the rearward view video images to the video display screen. When the vehicle is traveling forward at a speed at or above the threshold speed, the ECU generates rearward view video images and provides the rearward view video images to the video mirror display screen.

First claim

The invention claimed is:

1. A vehicular display system, the vehicular display system comprising:
an electronic control unit (ECU) disposed at a vehicle equipped with the vehicular display system, wherein the ECU comprises electronic circuitry and associated software;
a plurality of bird's eye surround view cameras and a plurality of camera monitoring system (CMS) cameras disposed at the vehicle;
wherein the plurality of bird's eye surround view cameras comprises (i) a rear backup camera, (ii) a forward viewing camera at a front portion of the vehicle and (iii) side bird's eye surround view cameras at respective sides of the vehicle;
wherein each bird's eye surround view camera of the plurality of bird's eye surround view cameras captures image data and provides captured image data to the ECU;
wherein the plurality of CMS cameras comprises (i) a rearward viewing camera that has a different field of view than the rear backup camera and (ii) side rearward viewing CMS cameras at the respective sides of the vehicle having different fields of view than the side bird's eye surround view cameras;
wherein each CMS camera of the plurality of CMS cameras captures image data and provides captured image data to the ECU;
wherein the electronic circuitry of the ECU comprises an image processor operable to process image data captured by the plurality of bird's eye surround view cameras and by the plurality of CMS cameras;
a video display screen disposed in the vehicle and viewable by a driver of the vehicle, wherein the video display screen is operable to display video images derived from video images provided by the ECU;
a video mirror display screen disposed at an interior rearview mirror assembly of the vehicle, wherein the video mirror display screen is operable to display video images derived from video images provided by the ECU;
wherein, during a parking maneuver of the vehicle, the ECU, via processing of image data captured by at least the plurality of bird's eye surround view cameras, generates bird's eye surround view video images and provides the bird's eye surround view video images to the video display screen;
wherein, when the vehicle is traveling forward at a speed below a threshold speed, the ECU, via processing of image data captured by at least the plurality of CMS cameras, generates rearward view video images and provides the rearward view video images to the video display screen; and
wherein, when the vehicle is traveling forward at a speed at or above the threshold speed, the ECU, via processing of at least a portion of image data captured by at least the plurality of CMS cameras, generates rearward view video images and provides the rearward view video images to the video mirror display screen.

2. The vehicular display system of claim 1 , wherein the provided rearview video images are partial rearview images derived from the processed portion of the captured image data.

3. The vehicular display system of claim 2 , wherein the processed portion of the captured image data is adjustable.

4. The vehicular display system of claim 3 , wherein the processed portion of the captured image data is adjustable via a user input.

5. The vehicular display system of claim 3 , wherein the processed portion of the captured image data is adjustable via an orientation of the video mirror display screen of the interior rearview mirror assembly.

6. The vehicular display system of claim 1 , wherein the video mirror display screen is electrically connected to the ECU via a first coaxial cable, and wherein the ECU provides video images to the video mirror display screen via the first coaxial cable.

7. The vehicular display system of claim 6 , wherein the video display screen is electrically connected to the ECU via a second coaxial cable, and wherein the ECU provides video images to the video display screen via the second coaxial cable.

8. The vehicular display system of claim 1 , wherein, when a trailer is hitched to the vehicle, a rearward viewing trailer camera having a field of view at least rearward of the trailer captures image data and provides captured image data to the ECU.

9. The vehicular display system of claim 8 , wherein, with the trailer hitched to the vehicle, the bird's eye surround view video images include video images derived from at least a portion of image data captured by the rearward viewing trailer camera.

10. The vehicular display system of claim 9 , wherein, when the vehicle is shifted to a reverse gear, the video images are derived from a portion of image data corresponding to a lower region of the field of view of the rearward viewing trailer camera.

11. The vehicular display system of claim 9 , wherein, when the vehicle is shifted to park or a forward gear, the video images are derived from a portion of image data corresponding to an upper region of the field of view of the rearward viewing trailer camera.

12. The vehicular display system of claim 8 , wherein the ECU, via processing of image data captured by the rearward viewing trailer camera and the plurality of CMS cameras, generates see-through trailer video images and provides the see-through trailer video images to the video display screen or the video mirror display screen.

13. The vehicular display system of claim 12 , wherein, when the vehicle is traveling forward at a speed below a threshold speed, the ECU provides the see-through trailer video images to the video display screen.

14. The vehicular display system of claim 13 , wherein, when the vehicle is traveling forward at a speed at or above the threshold speed, the ECU provides the see-through trailer video images to the video mirror display screen of the interior rearview mirror assembly.

15. The vehicular display system of claim 1 , wherein, when the vehicle is traveling forward, the ECU, via processing of image data captured by at least the plurality of CMS cameras, is operable to generate rearward view video images and to provide rearward view video images to the video display screen and to the video mirror display screen.

16. The vehicular display system of claim 15 , wherein the rearward view video images provided to the video display screen provide different rearward views than the rearward views provided by the rearward view video images provided to the video mirror display screen.

17. The vehicular display system of claim 1 , wherein, during the parking maneuver of the vehicle, the ECU, via processing of image data captured by at least the plurality of bird's eye surround view cameras, generates other bird's eye surround view video images and provides the other bird's eye surround view video images to the video mirror display screen.

18. The vehicular display system of claim 17 , wherein the bird's eye surround view video images provided to the video display screen provide different bird's eye surround views than the bird's eye surround views provided by the other bird's eye surround view video images provided to the video mirror display screen.

19. The vehicular display system of claim 1 , wherein the video display screen is disposed at a center console of the vehicle.

20. A vehicular display system, the vehicular display system comprising:
an electronic control unit (ECU) disposed at a vehicle equipped with the vehicular display system, wherein the ECU comprises electronic circuitry and associated software;
a plurality of bird's eye surround view cameras and a plurality of camera monitoring system (CMS) cameras disposed at the vehicle;
wherein the plurality of bird's eye surroun
