ABSTRACT:
An anti-skid brake control system includes a detector for detecting the peak value of wheel acceleration in each cycle of skid control. The period of braking pressure increased is adjusted depending upon the detected peak value of the wheel acceleration. The duration for which the brake pressure increase operation continues corresponds to the period of time necessary for the pressure to increase to approximately a projected or assumed lock pressure. After this duration has expired, the braking pressure is held at the constant value obtaining at the end of the duration. Therefore, the braking pressure is maintained at approximately the lock pressure. By holding the braking pressure at constant value for a fixed period of time, optimal braking characteristics can be achieved.
