Abstract
An anti-skid brake control system is capable of optimizing vehicular braking characteristics in order to minimize the braking distance. The anti-skid brake control system takes a feature of the vehicle speed dependent wheel slippage threshold. For this, the anti-skid brake control system of the invention employs a wheel slippage threshold deriving means which derives a wheel slippage threshold on the basis of a vehicle speed. The wheel slippage threshold is compared with an actual wheel slippage detected on the basis of a vehicle speed and a wheel speed. Brake pressure in a wheel cylinder is reduced when the detected wheel slippage is increased across the wheel slippage threshold.
