Abstract
An avoidance route calculation part calculates an avoidance route for avoiding a collision between an own vehicle and an obstacle through a collision avoidance assist control (an automatic brake control and an automatic steering control). A post-avoidance route calculation part calculates a post-avoidance route. A post-avoidance route collision determination part determinates whether a secondary obstacle is present on the post-avoidance route. When the secondary obstacle is determined to be present, the automatic steering control is prohibited from being performed.
Claims9
A collision avoidance assist apparatus comprising:
- obstacle detection means configured to detect an obstacle which is present ahead of an own vehicle;
- alert means configured to alert a driver when a collision probability of a collision of said own vehicle with said detected obstacle becomes high;
- avoidance route calculation means configured to calculate an avoidance route for avoiding said collision between said own vehicle and said detected obstacle;
- collision avoidance assist control means configured to perform a collision avoidance assist control including an automatic brake control and an automatic turn control when said collision probability becomes high, said automatic brake control being a control for generating a braking force at respective wheels, and said automatic turn control being a control for changing a traveling direction of said own vehicle in such a manner that said own vehicle travels along said avoidance route;
- post-avoidance route calculation means configured to calculate, as a termination position of said avoidance route, a position at which said collision between said own vehicle and said obstacle is predicted to have been avoided on the assumption that said own vehicle travels along said avoidance route, and calculate, as a post-avoidance route, a route along which said own vehicle is predicted to travel for a period from a first time point at which said own vehicle passes through said termination position to a second time point at which a setting time elapses since said first time point;
- post-avoidance route collision determination means configured to determine whether or not another obstacle having a high collision probability of a collision of said own vehicle with said another obstacle is present on the assumption that said own vehicle travels along said post-avoidance route;
- and
- prohibition means configured to prohibit said collision avoidance assist control means from performing said automatic turn control when said post-avoidance route collision determination means determines that said another obstacle is present.
