Abstract

A vision system for a vehicle includes at least one camera disposed at a vehicle so as to have a field of view exterior of the vehicle. Control circuitry includes an image processor for processing image data captured by the camera. The image processor processes image data captured by the camera for a pedestrian detection system of the vehicle. The control circuitry, responsive at least in part to image processing of captured image data by the image processor, is operable to cause adjustment of the pedestrian detection system of the vehicle from regular sensitivity to higher sensitivity. Adjustment from regular sensitivity to higher sensitivity is at least in part responsive to image processing of captured image data by the image processor determining that the vehicle is in the vicinity of children that a driver of the vehicle should watch out for.

First claim

The invention claimed is:

1. A vision system for a vehicle, said vision system comprising:
at least one camera disposed at a vehicle equipped with said vision system, wherein said at least one camera has a field of view exterior of the equipped vehicle;
control circuitry comprising an image processor for processing image data captured by said at least one camera;
wherein said image processor processes image data captured by said at least one camera for a pedestrian detection system of the equipped vehicle;
wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor, is operable to cause adjustment of the pedestrian detection system of the equipped vehicle from regular sensitivity to higher sensitivity; and
wherein adjustment from regular sensitivity to higher sensitivity is at least in part responsive to image processing of captured image data by said image processor determining that the equipped vehicle is in the vicinity of children that a driver of the equipped vehicle should watch out for.

2. The vision system of claim 1 , wherein adjustment from regular sensitivity to higher sensitivity is at least in part responsive to image processing of captured image data by said image processor detecting a school zone sign.

3. The vision system of claim 2 , wherein said control circuitry comprises memory and wherein views of school zone signs are stored in said memory.

4. The vision system of claim 2 , wherein, at least in part responsive to image processing of captured image data by said image processor detecting a school zone sign, an audio system of the equipped vehicle is muted so as to permit the driver of the equipped vehicle to be more attuned to the presence of any children nearby.

5. The vision system of claim 1 , wherein, at least in part responsive to image processing of captured image data by said image processor, at least one of (i) a child with a backpack is detected, (ii) a person riding a bicycle is detected and (iii) a person riding a scooter is detected.

6. The vision system of claim 1 , wherein a global positioning system of the equipped vehicle determines that the equipped vehicle is in the vicinity of a school.

7. The vision system of claim 1 , wherein a global positioning system of the equipped vehicle determines that the equipped vehicle is in the vicinity of a playground.

8. The vision system of claim 1 , wherein said control circuitry, at least in part responsive to image processing of captured image data by said image processor, causes the equipped vehicle to generate an audible signal upon detection of a pedestrian that is a potential collision risk.

9. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor detecting a type of vehicle exterior of the equipped vehicle, is operable to control an HVAC system of the equipped vehicle responsive to the type of vehicle detected exterior of the equipped vehicle.

10. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor detecting a school zone sign, is operable to cause adjustment of an audio system of the equipped vehicle.

11. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor and responsive to detection of a pedestrian that is a potential collision risk, is operable to cause generation of an audible signal that is audible exterior of the equipped vehicle.

12. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor detecting a construction zone, is operable to control an HVAC system of the equipped vehicle.

13. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to image processing of captured image data by said image processor determining the presence of a pothole in the path of travel of the equipped vehicle, is operable to cause adjustment of a suspension system of the equipped vehicle.

14. The vision system of claim 1 , wherein said control circuitry, responsive at least in part to said image processing of captured image data determining the presence of an emergency vehicle, is operable to cause adjustment of an audio system of the equipped vehicle.

15. The vision system of claim 1 , wherein said at least one camera comprises a forward-viewing camera having a forward field of view ahead of the equipped vehicle.

16. A vision system for a vehicle, said vision system comprising:
a forward-viewing camera disposed at a vehicle equipped with said vision system, wherein said forward-viewing camera has a field of view exterior and ahead of the equipped vehicle;
control circuitry comprising an image processor for processing image data captured by said forward-viewing camera;
wherein said image processor processes image data captured by said forward-viewing camera for a pedestrian detection system of the equipped vehicle;
wherein, at least in part responsive to image processing of captured image data by said image processor, a school zone sign is detected;
wherein said control circuitry, responsive at least in part to detection of a school zone sign, is operable to cause adjustment of the pedestrian detection system of the equipped vehicle from regular sensitivity to higher sensitivity; and
wherein, at least in part responsive to image processing of captured image data by said image processor, at least one of (i) a child with a backpack is detected, (ii) a person riding a bicycle is detected and (iii) a person riding a scooter is detected.

17. The vision system of claim 16 , wherein said control circuitry, at least in part responsive to image processing of captured image data by said image processor, controls the equipped vehicle to generate an audible signal upon detection of a pedestrian that is a potential collision risk.

18. A vision system for a vehicle, said vision system comprising:
at least one camera disposed at a vehicle equipped with said vision system, wherein said at least one camera has a field of view exterior of the equipped vehicle;
control circuitry comprising an image processor for processing image data captured by said at least one camera;
wherein said image processor processes image data captured by said at least one camera for a pedestrian detection system of the equipped vehicle;
wherein, at least in part responsive to image processing of captured image data by said image processor, a school zone sign is detected;
wherein, at least in part responsive to image processing of captured image data by said image processor, a child with a backpack is detected; and
at least one of (i) an audio system of the equipped vehicle is muted at least in part responsive to image processing of captured image data by said image processor detecting the school zone sign so as to permit the driver of the equipped vehicle to be more attuned to the presence of any children nearby and (ii) said control circuitry, at least in part responsive to image processing of captured image data by said image processor, controls the equipped vehicle to generate an audible signal upon detection of a pedestrian that is a potential collision risk.

19. The vision system of claim 18 , wherein, at least in part responsive to image processing of captured image data by said image proce
