Abstract

A safety system for a vehicle includes an imaging sensor and an image processor. The image sensor has an exterior rearward field of view. The imaging sensor captures image data and the image processor is operable to process captured image data to detect an object approaching the subject vehicle from rearward of the subject vehicle. The safety system is operable to determine if the detected object is likely to collide (or that a collision is probable or imminent or unavoidable or substantially unavoidable) with the subject vehicle and is operable to adjust a safety feature of the vehicle before the collision occurs. The safety system may be operable to adjust or vibrate or reposition a headrest of a seat in the subject vehicle responsive to determination that the detected object is likely to collide with the subject vehicle.

Claims

1. A safety system for a vehicle, said safety system comprising:

an imaging sensor having an exterior rearward field of view, said imaging sensor capturing image data;

an image processor operable to process image data captured by said imaging sensor to detect an object approaching the subject vehicle from rearward of the subject vehicle; and

wherein said safety system is operable to determine if the detected object is likely to collide with the subject vehicle and is operable to adjust a safety feature of the subject vehicle before the collision occurs.

2. The safety system of claim 1, wherein said safety system is operable to adjust a position of a headrest of a seat in the subject vehicle responsive to determination that the detected object is likely to collide with the subject vehicle.

3. The safety system of claim 2, wherein said safety system is operable to move the headrest of an occupied seat forward to limit rearward movement of an occupant'"'"'s head when the collision with the detected object occurs.

4. The safety system of claim 3, wherein said safety system is operable to adjust the position of the headrest of a seat responsive to a detection that the seat is occupied by an occupant of the vehicle.

5. The safety system of claim 1, wherein said safety system is operable to adjust a headrest of a seat in the subject vehicle responsive to determination that the detected object is likely to collide with the subject vehicle.

6. The safety system of claim 5, wherein said headrest is adjustable to provide a haptic alert to the seat occupant to alert the seat occupant of the potential collision.

7. The safety system of claim 6, wherein said safety system is operable to move the headrest forward to limit rearward movement of the seat occupant'"'"'s head when the collision with the detected object occurs.

8. The safety system of claim 1, wherein said safety system is operable to communicate an alert to a telematics system of the vehicle responsive to determination of a rear collision of the subject vehicle.

9. The safety system of claim 1, wherein said imaging sensor is disposed at a rearward portion of the vehicle.

10. A safety system for a vehicle, said safety system comprising:

an imaging sensor having an exterior rearward field of view, said imaging sensor capturing image data;

an image processor operable to process image data captured by said imaging sensor to detect an object approaching the subject vehicle from rearward of the subject vehicle; and

wherein said safety system is operable to determine if the detected object is likely to collide with the subject vehicle and wherein, responsive to said determination of a likely collision, said safety system is operable to adjust a headrest of a seat of the subject vehicle.

11. The safety system of claim 10, wherein said safety system is operable to adjust a position of the headrest of the seat responsive to determination that the detected object is likely to collide with the subject vehicle.

12. The safety system of claim 11, wherein said safety system is operable to move the headrest of an occupied seat forward to limit rearward movement of an occupant'"'"'s head when the collision with the detected object occurs.

13. The safety system of claim 12, wherein said safety system is operable to adjust the position of the headrest of a seat responsive to a detection that the seat is occupied by an occupant of the vehicle.

14. The safety system of claim 10, wherein said headrest is adjustable to provide a haptic alert to the seat occupant to alert the seat occupant of a potential rearward collision.

15. The safety system of claim 14, wherein said safety system is operable to move the headrest forward to limit rearward movement of the seat occupant'"'"'s head when a rearward collision with the detected object occurs.

16. The safety system of claim 10, wherein said safety system is operable to communicate an alert to a telematics system of the vehicle responsive to determination of a rear collision of the subject vehicle.

17. The safety system of claim 10, wherein said imaging sensor is disposed at a rearward portion of the vehicle.

18. A safety system for a vehicle, said safety system comprising:

an imaging sensor disposed at a rearward portion of the vehicle and having an exterior rearward field of view, said imaging sensor capturing image data;

an image processor operable to process image data captured by said imaging sensor to detect an object approaching the subject vehicle from rearward of the subject vehicle;

wherein said safety system is operable to determine if the detected object is likely to collide with the subject vehicle and wherein, responsive to said determination of a likely collision, said safety system is operable to adjust a position of a headrest of a seat of the subject vehicle; and

wherein said safety system is operable to adjust the position of the headrest of a seat responsive to a detection that the seat is occupied by an occupant of the vehicle.

19. The safety system of claim 18, wherein said safety system is operable to move the headrest of an occupied seat forward to limit rearward movement of an occupant'"'"'s head when the collision with the detected object occurs.

20. The safety system of claim 18, wherein said headrest is adjustable to provide a haptic alert to the seat occupant to alert the seat occupant of a potential rearward collision.

21. The safety system of claim 18, wherein said safety system is operable to communicate an alert to a telematics system of the vehicle responsive to determination of a rear collision of the subject vehicle.
