Abstract
An automatic brake control system of a vehicle for automatically applying brake when said vehicle comes near to an obstacle ahead comprises an own vehicle speed detector for detecting a speed of the vehicle, a distance detector for detecting a distance between the own vehicle and the obstacle, an obstacle speed calculating device for calculating a speed of the obstacle based on the speed of the vehicle and the distance between the vehicle and the obstacle, a stop control judging device for making a comparison of the distance between the vehicle and the obstacle with a threshold distance, a target deceleration establishing apparatus based on the comparison for establishing a target deceleration to a first deceleration when the distance is smaller than the threshold distance and to a second deceleration when the distance is larger than the threshold distance and a brake drive controller for performing a deceleration control so as to generate a brake fluid pressure corresponding to the target deceleration in a brake drive apparatus.
