Braking control apparatus

A braking control apparatus, comprising:

• a brake operating member adapted to be operated by a driver;
• a hydraulic circuit supplying a wheel cylinder hydraulic pressure to a wheel cylinder provided at each wheel;
• a pump driven by rotations of a motor and generating a hydraulic pressure at the hydraulic circuit so that the wheel cylinder hydraulic pressure reaches a value in response to an operation of the brake operating member;
• 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;
• a pressure regulating valve adjusting a pressure difference between an upstream side of the pressure regulating valve connected to the wheel cylinder of the hydraulic circuit and a downstream side of the pressure regulating valve;
• and
• a controlling means calculating, on the basis of a circulation flow rate of the brake fluid passing through the pressure regulating valve, an applied current to the pressure regulating valve for obtaining a target of the pressure difference and controlling the applied current.
