A collision avoidance system of a vehicle includes a camera disposed at a vehicle and having a field of view exterior of and rearward of the vehicle. An image processor is operable to process image data captured by the camera. Responsive to image processing of captured image data, the collision avoidance system is operable to determine an approach of a vehicle rearward of the vehicle and to determine an excitation level depending on a difference between the speed of the approaching vehicle and the speed of the equipped vehicle and a distance between the approaching vehicle and the equipped vehicle. Responsive to the determined excitation level, the collision avoidance system may provide an alert to the driver of one or both vehicles, prepare for impact, control a vehicle braking system, vehicle steering system and/or vehicle acceleration system and/or communicate information to the approaching vehicle via a telematics system. |

1. A collision avoidance system of a vehicle, said collision avoidance system comprising:
a camera disposed at a vehicle equipped with said collision avoidance system, said camera having a field of view exterior of and rearward of the equipped vehicle; an image processor operable to process image data captured by said camera; wherein, responsive to image processing of captured image data, said collision avoidance system is operable to determine an approach of a vehicle rearward of the equipped vehicle and to determine an excitation level depending on (i) a difference between the speed of the approaching vehicle and the speed of the equipped vehicle and (ii) a distance between the approaching vehicle and the equipped vehicle; wherein, responsive to a determined excitation level, said collision avoidance system is operable to at least one of (a) provide an alert to the driver of the equipped vehicle, (b) provide a visual alert to the driver of the approaching vehicle, (c) prepare the equipped vehicle for impact, (d) control a braking system of the equipped vehicle, (e) control a steering system of the equipped vehicle and (f) control an acceleration system of the equipped vehicle; and wherein, responsive to a determined excitation level, said collision avoidance system is operable to at least one of (i) transmit an alert to the driver of the approaching vehicle via a telematics system and (ii) communicate information to the approaching vehicle via a telematics system. |
