Included are pressure increasing valves (NO FL , NO FR . NO RL and NO RR ) and pressure reducing valves (NC FL , NC FR , NC RL and NC RR ) as flow control valves, placed between a brake fluid pressure generation unit (5) on an upstream side that generates brake fluid pressure and a braking force generation unit (7) on a downstream side that generates braking force in accordance with the brake fluid pressure to a wheel (Wfl, Wfr, Wrl or Wrr), that regulates the brake fluid pressure to the braking force generation unit (7) by controlling the flow rate of brake fluid, and an electronic control unit (1) is provided with: a differential pressure obtaining means 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 means 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 means that controls the flow control valve by use of the information on the differential pressure and the information on the hydrodynamic force.
