COLLISION AVOIDANCE ASSIST APPARATUS

There is provided a collision avoidance assist apparatus that includes an object detection sensor 11 that detects a relative speed Vr between a vehicle and an object ahead, a brake unit 20 that brakes the vehicle so as to avoid collision with the object ahead, and a control unit 30 that sets a set braking time tbd that will be taken for the relative speed Vr to reach zero based on set deceleration dd determined depending on a braking ability of the vehicle, and controls the brake unit 20 such that the braking of the vehicle is continued over the set braking time tbd.
