Included are pressure increasing valves and pressure reducing valves as flow control valves, placed between a brake fluid pressure generation unit on an upstream side that generates brake fluid pressure and a braking force generation unit on a downstream side that generates braking force in accordance with the brake fluid pressure to a wheel, that regulates the brake fluid pressure to the braking force generation unit by controlling the flow rate of brake fluid, and an electronic control unit is provided with: a differential pressure obtaining unit that obtains information on the difference of brake fluid pressure from the brake fluid pressure on upstream and downstream sides of the flow control valve; a hydrodynamic force obtaining unit that obtains information on hydrodynamic force induced in a valve element by the flow of brake fluid passing through the flow control valve; and a brake fluid pressure control unit that controls the flow control valve by use of the information on the differential pressure and the information on the hydrodynamic force.
