A brake hydraulic pressure control device for a vehicle is provided in which operation of a hydraulic pressure adjustment unit that can carry out adjustment involving individually increasing/decreasing brake hydraulic pressures applied to wheel brakes for front wheels and wheel brakes for rear wheels is controlled so as to be an allowable differential pressure between brake hydraulic pressures of the left and right wheel brakes, wherein allowable differential pressure setting means (27) is arranged so that the allowable differential pressure can be set so as to correspond to the coefficient of friction of a road surface, hydraulic pressure acquisition means (29) acquires a lock hydraulic pressure, which is a hydraulic pressure when starting anti-lock brake control for the respective wheel brake, and when the lock hydraulic pressure of the wheel brakes for the front wheels acquired by the hydraulic pressure acquisition means (29) is no greater than a predetermined value which can be determined as to be a low coefficient of friction, application of the allowable differential pressure corresponding to the coefficient of friction of the road surface is prohibited. Thus, it is possible to independently control the brake hydraulic pressure of left and right wheel brakes according to road surface conditions. |
