Abstract

A display system for a vehicle comprises display screens mounted within a passenger compartment of a vehicle. Cameras are mounted on the exterior of the vehicle corresponding to the positions of the display screens. A sensor(s) is directed toward a driver for the vehicle to sense a driver eye position. An ECU for the display system analyzes the driver eye position and determines a line of sight. An image from the camera is displayed on the display screen that corresponds to the driver'"'"'s line of sight. Consequently, rather than the vehicle obstructing the driver'"'"'s view the display system provides images to the driver of what would be seen if the vehicle body was not there. Thus, the display system provides virtually transparent portions of the vehicle body which widens the field of view provided to the driver.

Claims

1. A display system for a vehicle comprising:

a first display screen mounted at a first mounting position for the vehicle to display a first image visible to a driver;

an electronic control unit controllably connected to the first display screen;

a camera mounted to the exterior of the vehicle to record an area proximate to the vehicle, wherein a recorded image is sent to the electronic control unit;

at least one sensor within the passenger compartment directed toward a driver seat to detect eye position of a driver, wherein the electronic control unit determines a predicted line of sight for the driver to the first display screen based upon the eye position; and

wherein electronic control unit selects the first image from the recorded image based upon a predicted line of sight of the driver.

2. The display system of claim 1, wherein the electronic control unit determines the first image displayed on the first display screen by one of:

using a portion of the recorded image provided by the camera that relates to the predicted line of sight, and changing the camera viewing angle to provide a recorded image relating to the predicated line of sight.

3. The display system of claim 1, wherein the first mounting position is an A-pillar of the vehicle.

4. The display system of claim 1, wherein the at least one sensor is one of a camera and an ultrasonic sensor.

5. The display system of claim 1, wherein the first display screen is one of a low density color display screen and a plurality of low density color display screens mounted at the first mounting position.

6. The display system of claim 1, wherein the camera is a fish-eye camera.

7. A display system for a vehicle comprising:

a plurality of display screens mounted to a plurality of mounting positions on the vehicle to display a plurality of images visible to a driver;

at least one electronic control unit controllably connected to the plurality of display screens;

a plurality of cameras mounted to the exterior of the vehicle at the mounting positions to provide images from outside of the vehicle, wherein the mounting positions for the plurality of cameras corresponds to the mounting positions of the plurality of display screens;

a plurality of sensors within the passenger compartment directed toward a driver seat; and

a plurality of images displayed on the plurality of display screens, wherein the image on each of the plurality of display screens is determined by the electronic control unit using information from the at least one sensor based upon a predicted point of view of the driver for the each of the plurality of display screens.

8. The display system of claim 7, wherein the plurality of display screen mounting position is one of a driver side A-pillar, a passenger side A-pillar, and of the vehicle.

9. The display system of claim 7, wherein the plurality of sensors is one of a camera and at least one ultrasonic sensor;

a plurality of ultrasonic sensors, and a plurality of cameras.

10. The display system of claim 7, wherein each of the plurality of display screens are one of a low density color display screen and a plurality of low density color display screens mounted at that mounting position of the plurality of display screens.

11. The display system of claim 7, wherein the plurality of cameras are fish-eye cameras.

12. The display system of claim 7, wherein the electronic control unit determines the image displayed on each of the corresponding plurality of display screens by one of:

using a portion of the image provided by the corresponding one of the plurality of cameras that relates to the predicted point of view of the driver, and changing the viewing angle of the corresponding one of the plurality of cameras to provide images relating to the predicated point of view of the driver.

13. A method of displaying an image in vehicle comprising:

recording a first image of an area proximate to the vehicle with a camera mounted to the vehicle;

sensing eye position of a driver with at least one sensor located within a passenger compartment for the vehicle;

determining a line of sight for the driver based upon the eye position and corresponding to a position of a display screen mounted within passenger compartment of the vehicle and visible to the driver;

displaying a second image on the display screen, wherein the second image displayed corresponds to the line of sight the driver for the mounting position of the display screen.

14. The method of claim 13, wherein the second image is a portion of the first image selected based upon the eye position of the driver.

15. The method of claim 13, further comprising moving the camera to obtain a different point of view when recording the first image based upon the eye position of the driver and wherein the second image on the display screen is the same as the first image recorded by the camera.

16. The method of claim 13, wherein the first mounting position is an A-pillar of the vehicle.

17. The method of claim 13, wherein the at least one sensor is one of a camera and an ultrasonic sensor.
