BRAKING CONTROL APPARATUS

PROBLEM TO BE SOLVED: To provide a braking control apparatus capable of improving control accuracy of a wheel cylinder hydraulic pressure. SOLUTION: This braking control apparatus includes a brake operating member operated by a driver, a hydraulic circuit supplying a wheel cylinder hydraulic pressure, a pump generating a hydraulic pressure which is driven by the operation of a motor and generating the hydraulic pressure to the hydraulic pressure circuit so that the wheel cylinder hydraulic pressure reaches a value in response to an operation of the brake operating member, and a circulation conduit provided at a portion of the hydraulic circuit, the circulation conduit through which a partial amount of brake fluid discharged from the pump is circulated back to the pump. The apparatus includes a pressure regulating valve capable of adjusting a pressure difference Pd between an upstream side of the pressure regulating valve connected to the wheel cylinder and a downstream side, and controlling means calculating, on the basis of a circulation flow rate of the brake fluid passing through the pressure regulating valve, an applied current I to the pressure regulating valve for obtaining a target of the pressure difference Pd and controlling the current I applied to the pressure regulating valve.
