To suppress variation of braking force and operation feeling when control is performed such that a brake fluid pressure of a part of a wheel brake becomes a higher pressure than an output fluid pressure of a fluid pressure generation means in a brake fluid pressure control device for a vehicle for controlling operation of a fluid pressure control unit such that the brake fluid pressure of the wheel brake of a part of the respective wheel brakes is made to a fluid pressure of higher pressure than the fluid pressure of the fluid pressure generation means during brake operation.
In the state that the fluid pressure control unit is controlled by a controller such that the fluid pressure of the wheel brake of a part of the wheel brakes is increased than the output fluid pressure of the fluid pressure generation means during brake operation, the fluid pressure of the non-increase pressure wheel brake gives hysteresis characteristic to a brake operation amount. Thereby, the fluid pressure control unit is controlled by the controller C so as to become a target fluid pressure operated by the non-increase pressure wheel target fluid pressure operation part 28.
