Abstract

A vehicle collision avoidance system has a camera disposed on a vehicle and arranged to monitor at least one collision prone region adjacent to the vehicle; a sensor positioned within the vehicle and arranged to determine a driver'"'"'s head position relative to a designated point in the vehicle; a display disposed in view of the driver and coupled to the camera; and a controller configured to control operation of the sensor, the camera and the display. The controller activates the display and the camera to display the at least one collision prone region adjacent to the vehicle when the sensor detects that the driver'"'"'s head is beyond a threshold distance from the designated point.

Claims

1. A vehicle collision avoidance system comprising:

a camera disposed on a vehicle and arranged to monitor at least one collision prone region adjacent to said vehicle;

a sensor positioned within said vehicle and arranged to determine a driver'"'"'s head position relative to a designated point in said vehicle;

a display disposed in view of said driver, said display coupled to said camera; and

a controller configured to control operation of said sensor, said camera and said display, the controller being configured to activate said display and said camera to display said at least one collision prone region adjacent to said vehicle when said sensor detects that said driver'"'"'s head is beyond a threshold distance from said designated point.

2. The vehicle collision avoidance system as in claim 1, wherein said camera is a wide field of view camera disposed on a rear area of said vehicle and arranged to image an area near a rear bumper of the vehicle.

3. The vehicle collision avoidance system as in claim 2, further comprising a normal field of view camera disposed on a rear area of said vehicle and arranged to image the area behind said vehicle, said normal field of view camera being coupled to said display and operationally controlled by said controller.

4. The vehicle collision avoidance system as in claim 3, wherein said wide field of view camera and said normal field of view camera are provided in a single camera with a field of view adjustable by said controller.

5. The vehicle collision avoidance system as in claim 1, further comprising an electronically adjustable side-view mirror, wherein said side-view mirror is controllably adjusted by said controller in response to said driver'"'"'s head position.

6. The vehicle collision avoidance system as in claim 1, wherein said camera is disposed at a forward area of said vehicle and arranged to image a region encompassing both sides of said vehicle forward of a front of said vehicle.

7. A vehicle collision avoidance method for a motor vehicle, comprising the steps of:

detecting a body movement by a driver;

evaluating said body movement to determine if said body movement exceeds a threshold distance; and

activating a collision avoidance process when said body movement exceeds said threshold distance.

8. The method as in claim 7, wherein said body movement is a forward-leaning movement, and said threshold distance is measured from a driver'"'"'s seat headrest.

9. The method as in claim 8, wherein said collision avoidance process further comprising the steps of:

detecting whether said motor vehicle is in a non-reverse gear;

activating a front-view camera when said motor vehicle is in said non-reverse gear; and

transmitting a video signal from said front-view camera to a display viewable by said driver.

10. The method as in claim 9, wherein said front-view camera has at least a 180°

field of view forward of said motor vehicle.

11. The method as in claim 10, wherein said front-view camera comprises a plurality of cameras configured to provide said 180°

field of view.

12. The method as in claim 8, wherein said collision avoidance process further comprising the steps of:

detecting whether said motor vehicle is in a reverse gear;

activating a rear-view camera when said motor vehicle is in said reverse gear; and

transmitting a video signal from said rear-view camera to a display viewable by said driver.

13. The method as in claim 12, wherein said rear-view camera is configured to provide view behind said motor vehicle.

14. The method as in claim 13, further comprising the steps of:

processing said video signals to provide a normal view to said driver when said body motion is less that said threshold distance and greater than a second threshold distance; and

processing said video signals to provide a wide angle view to said driver when said body motion exceeds said threshold distance.

15. The method as in claim 14, further comprising the steps of:

adjusting a side-view mirror to provide a side parking view to said driver when said body motion exceeds said threshold distance; and

adjusting said side-view mirror to provide a normal driving view to said driver when said body motion is less that said threshold distance and greater than said second threshold distance.

16. A vehicle collision avoidance system, comprising:

a first sensor configured to determine a distance between a driver and a surface of a seat;

a second sensor configured to detect a transmission gear selection;

a third sensor configured to sense a traveling velocity of said vehicle;

a first camera system positioned at a front-most position on said vehicle and oriented to image an area encompassing at least 180°

around the front of said vehicle;

a second camera system positioned at a rear-most position on said vehicle;

a display adapted to display video to said driver;

a controller in electrical communication with said first sensor, said second sensor, said third sensor, said first camera system, said second camera system, and said display, the controller being configured to provide video feeds from said first camera system and said second camera system based on an analysis of data provided to the controller by said first sensor, said second sensor, said third sensor; and

an energy source configured to energize said first sensor, said second sensor, said third sensor, said first camera system, said second camera system, said display and said controller.

17. The system as in claim 16, wherein said analysis of data comprises the first, second and third sensors being configured to:

determine if said distance between said driver and said surface of said seat exceeds a first threshold;

detect if said transmission gear is a reverse gear; and

sense if said traveling velocity of said vehicle is below 6 MPH.

18. The system as in claim 17, wherein said controller selectively provides said video feed from said first camera system to said display when said distance between said driver and said surface of said seat exceeds said first threshold, said transmission gear is not in said reverse gear, and said traveling velocity of said vehicle is below 6 MPH.

19. The system as in claim 17, wherein said controller selectively provides said video feed from said second camera system to said display when said distance between said driver and said surface of said seat exceeds said first threshold, said transmission gear is in said reverse gear, and said traveling velocity of said vehicle is below 6 MPH.

20. The system as in claim 17, further comprising a side-view mirror adjustment motor controlled by said controller, wherein

said controller drives said side-view mirror adjustment motor to adjust a side-view mirror to a default position when said traveling velocity of said vehicle is above 6 MPH, and

said controller drives said side-view mirror adjustment motor to adjust a side-view mirror to a reverse parking position when said distance between said driver and said surface of said seat exceeds said first threshold, said transmission gear is in said reverse gear, and said traveling velocity of said vehicle is below 6 MPH.
