COLLISION AVOIDANCE ASSISTANCE APPARATUS

A collision avoidance assist apparatus starts an autonomous steering control to autonomously steer and turn an own vehicle to orient the own vehicle in a laterally extending direction of an obstacle to avoid a collision of the own vehicle with the obstacle when the own vehicle potentially collides with the obstacle. The apparatus sets a first condition as a control termination condition used to determine whether to terminate the autonomous steering control, based on a laterally extending direction of the obstacle relative to the own vehicle when starting the autonomous steering control. The apparatus terminates the autonomous steering control when the obstacle is tracked, and a second condition different from the first condition becomes satisfied. The apparatus terminates the autonomous steering control when the obstacle is not tracked, and the first condition becomes satisfied.
