An anti-skid brake control system is designed to minimize inaccuracies due to the intervals between wheel acceleration value derivations by deriving extrapolated adjustment values for the wheel acceleration value between derivations. The anti-skid brake control system periodically adjusts, i.e. either increases and decreases the wheel acceleration value depending upon the increase and decrease of the braking pressure. The wheel acceleration value is increased at a given rate while the braking pressure decreases and is decreased at a given rate while the braking pressure is increased, during the interval between wheel acceleration calculations.

An anti-skid brake control system for an automotive brake system comprising: a hydraulic brake system including a pressure control valve for adjusting braking pressure on a vehicle wheel, said pressure control valve having operation modes for performing braking pressure adjustment through at least one skid cycle which include a first mode for increasing braking pressure and a second mode for decreasing braking pressure; a wheel speed sensor monitoring rotation speed of said vehicle wheel and producing a sensor signal; a controller for controlling said pressure control valve so as to prevent the wheel from skidding, said controller periodically calculating a wheel acceleration value over a given interval on the basis of said sensor signal, and extrapolating changes in said wheel acceleration value in accordance with a predetermined extrapolation coefficient which varies with the operation mode of said pressure control valve, said controller further deriving a wheel slippage value on the basis of said sensor signal, and a control signal for ordering said pressure control valve to an operation mode selected according to said wheel acceleration value and said wheel slippage value.
