摘要:
In a braking pressure control apparatus for a vehicle, a first valve connected between a hydraulic pressure source and a wheel cylinder serves to permit and inhibit a supply of brake fluid to the wheel cylinder from the hydraulic pressure source. A second valve connected between the wheel cylinder and a reservoir serves to permit and inhibit an escape of the brake fluid from the wheel cylinder toward the reservoir. A control device serves to output control signals to the first and second valves respectively to control the braking pressure in the wheel cylinder in response to a detected running condition of the vehicle. The control device includes a deciding section for deciding whether or not a small variation in the braking pressure in the wheel cylinder should be done on the basis of the detected running condition of the vehicle, and an outputting section for, when the deciding section decides that the small variation in the braking pressure in the wheel cylinder should be done, simultaneously outputting the control signals to the first and second valves to simultaneously execute the supply of the brake fluid to the wheel cylinder and the escape of the brake fluid from the wheel cylinder.
