Vehicular vision system
First Claim
1. A vision system for a vehicle, said vision system comprising:
- a forward viewing camera disposed at a vehicle equipped with said vision system, said camera viewing generally forwardly of the equipped vehicle;
an image processor operable to process image data captured by said camera;
a control responsive to said image processor;
wherein, responsive to image processing of captured image data, said control is operable to detect a traffic light viewed by said camera and is operable to determine when the detected traffic light is exhibiting an illuminated red traffic light signal or an illuminated green traffic light signal;
wherein, responsive to image processing of captured image data, said control is operable to detect a vehicle stopped in front of and in the same lane as the equipped vehicle;
wherein, responsive at least in part to a determination that (i) the equipped vehicle is not moving when the detected traffic light is exhibiting an illuminated red traffic light signal, (ii) the traffic light signal of the detected traffic light changes to an illuminated green traffic light signal, and (iii) the detected vehicle in front of and in the same lane as the equipped vehicle moves forwardly away from the non-moving equipped vehicle, said vision system at least one of (a) generates an alert to a driver of the equipped vehicle and (b) autonomously controls forward movement of the equipped vehicle;
wherein, when the equipped vehicle is moving and responsive at least in part to a determination that the moving equipped vehicle is approaching an object determined to be present forwardly of the equipped vehicle, said vision system is operable to apply a vehicle brake of the equipped vehicle to mitigate a collision with the determined object; and
wherein said vision system comprises a rearward viewing camera viewing generally rearwardly of the equipped vehicle, and wherein said image processor is operable to process image data captured by said rearward viewing camera, and wherein, responsive at least in part to a determination via said image processing that another vehicle is following the moving equipped vehicle and (i) within a threshold distance from the equipped vehicle and (ii) approaching the equipped vehicle beyond a threshold rate of approach, said vision system adjusts application of the vehicle brakes to mitigate a rear collision by the determined following vehicle.

Abstract
A vision system for a vehicle includes a camera disposed at a vehicle and viewing forwardly of the vehicle. An image processor is operable to process image data captured by the camera. Responsive at least in part to a determination that the vehicle is at a red light and the red light turns green and another vehicle in front of the vehicle moves forwardly away from the vehicle, the system may generate an alert to the driver of the vehicle. The system may include a camera that views rearwardly of the vehicle. Responsive to a determination that the vehicle is approaching an object present forwardly of the vehicle, the system may apply a vehicle brake to mitigate a collision with the determined object, and the system may reduce application of the vehicle brakes to mitigate a rear collision by a determined following vehicle.

12. A vision system for a vehicle, said vision comprising:
-
a forward viewing camera disposed at a vehicle equipped with said vision system, said forward viewing camera viewing generally forwardly of the equipped vehicle; a rearward viewing camera disposed at the equipped vehicle, said rearward viewing camera viewing generally rearwardly of the equipped vehicle; an image processor operable to process image data captured by said forward viewing camera and said rearward viewing camera; wherein, responsive at least in part to a determination by said image processor that the equipped vehicle is approaching an object present forwardly of the equipped vehicle and in the path of travel of the equipped vehicle, a control is operable to apply a vehicle brake of the equipped vehicle to mitigate a collision with the determined object; and wherein, responsive at least in part to a determination by said image processor that another vehicle is following the equipped vehicle in the lane traveled by the equipped vehicle and at least one of (i) within a threshold distance from the equipped vehicle and (ii) approaching the equipped vehicle beyond a threshold rate of approach, said control reduces application of the vehicle brakes to mitigate a rear collision by the determined following vehicle. - View Dependent Claims (13, 14, 15)
