PROBLEM TO BE SOLVED: To provide a brake control device for a vehicle which is further reduced in size and inexpensive.SOLUTION: A brake control device 10 for a vehicle comprises a hydraulic circuit 20 which connects a master cylinder 12 and a wheel cylinder 35, an inlet control valve 15 and an outlet control valve 16 which control brake hydraulic pressure, and a pump 14. The brake control device also comprises a release passage 29 which returns a brake fluid at the wheel cylinder 35 side to a reservoir tank 13, a suction side of the pump 14 communicates with the reservoir tank 13, a discharge side of the pump 14 communicates with the wheel cylinder 35 side, and the inlet control valve 15 and the outlet control valve 16 switch communication and blocking between the master cylinder 12 and the wheel cylinder 35, also switch communication and blocking between the wheel cylinder 35 and the reservoir tank 13, and control the brake fluid pressure.EFFECT: There is no necessity for differently installing an accumulator as before, and since the accumulator is not separately arranged, the size reduction and cost reduction can be promoted.SELECTED DRAWING: Figure 1 |
