Abstract:
An automatic brake control system of a vehicle for automatically applying brake when said vehicle comes near to an obstacle ahead, having wheels, wheel cylinders of said wheels, a steering wheel, a brake pedal, an accelerator pedal and a brake drive apparatus for generating a brake fluid pressure and feeding said brake fluid pressure to said wheel cylinders, comprising:an own vehicle speed detecting means for detecting a speed of said vehicle;a distance detecting means for detecting a distance between said vehicle and said obstacle;an obstacle speed calculating means for calculating a speed of said obstacle based on said speed of said vehicle and said distance between said vehicle and said obstacle;a stop control judging means for making a comparison of said distance between said vehicle and said obstacle with a threshold distance;a first deceleration establishing means for establishing a first deceleration based on said vehicle speed and a road gradient;a second deceleration establishing means for establishing a second deceleration based on said vehicle speed, said obstacle speed, and said distance between said vehicle and said obstacle;a target deceleration establishing means based on said comparison for establishing a target deceleration at said first deceleration when said distance is smaller than said threshold distance and at said second deceleration when said distance is larger than said threshold distance; anda brake drive controlling means for performing a deceleration control so as to generate said brake fluid pressure corresponding to said target deceleration in said brake drive apparatus.
