The drive assist apparatus detects an object around an own vehicle, and detects a moving direction of the detected object when the detected object is relatively approaching the own vehicle. The drive assist apparatus predicts a movement prediction position to which the object will move, and executes drive assist upon the movement prediction position being a collision prediction position. The collision prediction position is a position where, if the object relatively moves to the movement prediction position, there is a possibility that the object will collide with the own vehicle. The drive assist includes at least one of a task of avoiding a collision between the object and the own vehicle, and a task of mitigating a damage due to the collision. The drive assist apparatus determines an execution timing of the drive assist as a function of the moving direction detected by the moving direction detection means, and the collision prediction position.
