PROBLEM TO BE SOLVED: To provide a braking control device for vehicle capable of detecting rapidly a failure of a hydraulic valve adapted to switch a communicating state between a master cylinder and wheel cylinders of right and left pair of wheels in a state that a master cylinder pressure is automatically controlled in pressurizing and in a state that wheel cylinder pressures of the wheels being driven wheels are maintained. SOLUTION: This device comprises the master cylinder 20 of which the pressure is automatically controlled in pressurizing, holding valves 33a-36a adapted to switch a communicating state between the master cylinder 20 and the wheel cylinders 13-6 of each wheel and pressure reducing valves 33b-36a adapted to switch a communicating state between reservoirs 38, 39 and the wheel cylinders 13-16 of each wheel. When a difference in wheel speed of the right and left pair of wheels FR, FL exceeds an abnormality judging threshold in the state that the wheel cylinder pressures of the right and left pair of wheels FR, FL being driven wheels are maintained, the holding valve 33a or 34a of the wheel with a smaller wheel speed is judged to be abnormal. |
