Abstract

A vision display system for a vehicle includes a plurality of cameras having exterior fields of view, a first display screen disposed in an interior rearview mirror assembly of the vehicle, and a second display screen disposed at or in a console or instrument panel of the vehicle. The cameras include a rearward viewing camera, a forward viewing camera, a driver side viewing camera and a passenger side viewing camera. The second display screen has a diagonal dimension that is greater than a diagonal dimension of the first display screen. The first display screen is operable to display images captured by the rearward viewing camera during a reversing maneuver of the vehicle and the second display screen displays a surround view image formed as a composite image derived from image data captured by the rearward, forward, driver side and passenger side viewing cameras during a reversing maneuver of the vehicle.

Claims

1. A vision display system for a vehicle, said vision display system comprising:

a plurality of cameras disposed at the vehicle and having exterior fields of view, said plurality of cameras comprising a rearward viewing camera disposed at the rear of the vehicle, a forward viewing camera disposed at the front of the vehicle, a driver side viewing camera disposed at a driver side of the vehicle and a passenger side viewing camera disposed at a passenger side of the vehicle;

a first display screen disposed in an interior rearview mirror assembly of the vehicle, said first display screen having a first diagonal dimension;

a second display screen disposed at or in a console or instrument panel of the vehicle, said second display screen having a second diagonal dimension, wherein said second diagonal dimension is greater than said first diagonal dimension; and

wherein said first display screen is operable to display images captured by said rearward viewing camera during a reversing maneuver of the vehicle and wherein said second display screen displays a surround view image formed as a composite image derived from image data captured by said rearward, forward, driver side and passenger side viewing cameras during a reversing maneuver of the vehicle.

2. The vision display system of claim 1, wherein said first display screen comprises a video mirror display screen, and wherein video information displayed by said first display screen is viewable through a transflective mirror reflector of the mirror reflective element of said interior rearview mirror assembly of the vehicle.

3. The vision display system of claim 1, wherein said second display screen is operable to display at least one of (a) navigation information and (b) infotainment information for viewing by the driver of the vehicle other than when a reversing maneuver is being executed by the driver of the vehicle.

4. The vision display system of claim 1, wherein said system is operable to delay activating backlighting of at least one of said display screens for a period of time following an ignition on/engine startup event.

5. The vision display system of claim 4, wherein said system is operable to delay activating backlighting of said at least one of said display screens until receipt of a valid video signal from said rearward viewing camera.

6. The vision display system of claim 1, wherein said rearward viewing camera comprises a monochromatic camera with no color or infrared or near infrared filtering, and wherein at least one of said display screens comprises a monochromatic display screen with no color filtering.

7. The vision display system of claim 1, wherein said driver side viewing camera is disposed at an exterior side view mirror assembly at the driver side of the vehicle.

8. The vision display system of claim 1, wherein said first display screen powers up during a rear backup event.

9. The vision display system of claim 8, wherein said first display screen displays said images captured by said rearward viewing camera within two seconds of an initial ignition of the vehicle.

10. A vision display system for a vehicle, said vision display system comprising:

a plurality of cameras disposed at the vehicle and having exterior fields of view, said plurality of cameras comprising a rearward viewing camera disposed at the rear of the vehicle, a forward viewing camera disposed at the front of the vehicle, a driver side viewing camera disposed at an exterior rearview mirror assembly at a driver side of the vehicle and a passenger side viewing camera disposed at an exterior rearview mirror assembly at a passenger side of the vehicle;
