<p>PROBLEM TO BE SOLVED: To provide a brake fluid pressure control device for a vehicle that can suppress influence of a pressure difference between two brake systems.SOLUTION: The brake fluid pressure control device for a vehicle includes: a plurality of pumps 4 each being provided in each of two brake systems; a plurality of cut valves 6 each being provided between discharge sides of the pumps and a master cylinder M; a plurality of suction valves 7 each being provided between suction sides of the pumps and the master cylinder; one motor 9 that drives the pumps; a valve drive part that drives and controls the cut valves and suction valves; and a motor drive part that drives and controls the motor. The valve drive part performs pressurization control that closes the cut valves and opens the suction valves and holding control that closes the cut valves and closes the suction valves when the motor drive part drives the motor; and differentiates the timing of closing of the respective suction valves to each other by a predetermined time on the basis of the state of rotation of the motor in switching from the pressurization control to the holding control.</p> |
