Abstract
An anti-skid brake control system which employs a process of projection of vehicle speed representative dats based on selected higher one of data derived based on an integrated value which is derived by integrating vehicle body acceleration indicative data by time and data derived on the basis of wheel speed. In the present invention, vehicle speed representing data is periodically or cyclically reset and updated by the vehicle speed as an initial value of the vehicle speed representative data with that derived on the basis of the wheel speed. By selectively using the higher one of the vehicle speed representative data and periodically or cyclically updating the initial value of the vehicle speed representative data, a precision level of the vehicle speed representative level can be maintained high enough to precisely derive a wheel slippage for performing precise anti-skid control.
