Abstract
A collision mitigation controller drives a target brake to be controlled for assisting driver's collision-avoidance operation when a calculated collision time is less than an automatic brake a1 judgment line which is determined in advance. The controller drives the automatic brake a1 in order to mitigate damage generated by a collision with an obstacle or another vehicle when the collision time is less than an automatic brake a2 judgment line which is also less than the automatic brake a1 judgment line. The controller decreases the braking force for the automatic brake a2 when judged that the automatic brake a1 is not driven, as compared with the judgment where the automatic brake a1 is driven. When the automatic brake a2 drives the target brake, it is possible to avoid a collision where own vehicle is struck from behind by the rear vehicle which runs on a same traffic lane.
