Claim:
1. A collision avoidance assist device configured to perform an assist for avoiding a collision between a vehicle and an object, the device comprising: an object detection unit that detects the object around the vehicle; a time calculation unit that calculates a time to collision between the vehicle and the object based on a detection result of the object detection unit; and an assist control unit that controls braking for avoidance assist and suppresses a release of the braking for avoidance assist in a case where the time to collision continuously decreases when an execution of the collision avoidance assist is controlled based on the time to collision, and suppresses the release of the braking for avoidance assist further after a predetermined time has passed from starting of the braking for avoidance assist than before the predetermined time has passed; wherein the assist control unit suppresses the release of the braking for avoidance assist by expanding a regulation range of a horizontal position of the collision that is used for determining a possibility of collision.
