<p>A driving assistance device (2) is provided with: a brake control unit (5) which executes avoidance brake control for avoiding a collision by keeping a predetermined distance from an obstacle on the basis of a time to collision, and reduction brake control for reducing damage caused by the collision against the obstacle by being executed when an avoidance limit relative speed that is a maximum relative speed at which the collision is avoidable while the distance to the obstacle is kept at the predetermined distance is exceeded when a deceleration index concerning the deceleration of a vehicle is a predetermined value or less; and an arithmetic processing unit (4) which calculates the execution timing of the reduction brake control by the brake control unit (5) with reference to the distance between the vehicle (1) and the obstacle at the execution timing of the avoidance brake control at the avoidance limit relative speed, and corrects the execution timing of the reduction brake control on the basis of the deceleration of the vehicle (1). Consequently, both collision avoidance control between the vehicle and the obstacle and damage reduction control at the time of the collision can be executed, and switching between both the controls can be performed smoothly.</p> |
