Vehicle vision system with collision mitigation

摘要

A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle. An image processing system is operable to process image data captured by the camera to determine the presence of a leading vehicle ahead of the equipped vehicle and to determine an illumination level of a taillight of the leading vehicle. Responsive to a determination of a relative speed of the leading vehicle relative to the equipped vehicle and a relative acceleration of the leading vehicle relative to the equipped vehicle, the vision system determines a braking level of the equipped vehicle to mitigate collision with the leading vehicle. Responsive to the determination of the illumination level of the taillight of the determined leading vehicle, the vision system is operable to apply a weighting factor to adjust the determined braking level for the determined traffic condition.

主权项

1. A vision system of a vehicle, said vision system comprising:
a camera disposed at a vehicle equipped with said vision system and having a field of view forward of the equipped vehicle; an image processor operable to process image data captured by said camera; wherein said image processor is operable, via image processing of captured image data, to determine the presence of a leading vehicle ahead of the equipped vehicle; wherein said image processor is operable, via image processing of captured image data, to determine illumination of a brake light of the determined leading vehicle; wherein, responsive to a determination of at least one of (a) a relative speed of the determined leading vehicle relative to the equipped vehicle and (b) a relative acceleration of the determined leading vehicle relative to the equipped vehicle, said vision system is operable to determine at least one of (i) a degree of warning to provide to the driver of the equipped vehicle and (ii) a braking level of the equipped vehicle to mitigate collision with the determined leading vehicle; and wherein, responsive to the determination of illumination of the brake light of the determined leading vehicle, said vision system is operable to at least one of (i) adjust the determined degree of warning and (ii) adjust the determined braking level of the equipped vehicle; and wherein said vision system is operable to at least one of (i) provide a warning in accordance with the determined degree of warning and (ii) apply the brakes of the equipped vehicle in accordance with the determined braking level.
