Automotive collision mitigation apparatus
First Claim
1. A collision mitigation apparatus, mounted to an automobile vehicle, capable of mitigating damage generated when the vehicle collides with obstacles including another vehicle by driving brake means mounted to the vehicle, comprising:
- obstacle detection means configured to detect obstacles which are present around own vehicle to which the collision mitigation apparatus is mounted;
collision time calculation means configured to calculate a collision time as an estimated time length until own vehicle collides with the obstacle detected by the obstacle detection means;
collision avoidance assist means configured to drive the brake means in order to assist the collision avoidance operation by a vehicle'"'"'s driver when the collision time is less than a predetermined assist time which is determined in advance;
collision damage mitigation means configured to drive the brake means in order to mitigate the damage when own vehicle collides with the obstacle when the collision time is less than a predetermined damage mitigation time which is less than the assist time.operation judgment means configured to judge whether or not the collision avoidance assist means drives the brake means; and
damage mitigation braking force reduction means configured to decrease the braking force of the brake means by the collision damage mitigation means when the operation judgment means judges that the collision assist avoidance means does not drive the brake means, as compared with the judgment in which the operation judgment means judges that the collision assist avoidance means drives the brake means.

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.
