ABSTRACT:
A brake control system includes devices for determining wheel r.p.m. for determining an acceleration rate of the wheel r.p.m. and generating a signal when the determined acceleration rate becomes equal to or greater than a predetermined value, and for determining a target wheel r.p.m. based on the wheel r.p.m. The target wheel determining device is operatively responsive to detection of the peak of the coefficient of friction. A control device is provided for controlling applying and releasing of fluid pressure to wheel cylinders for skid controlling the wheel deceleration rate. The target wheel r.p.m. determining device determines the rate of deceleration of wheel r.p.m. based on the difference of wheel r.p.m. between the detection time of a peak of the coefficient of friction and the detection time of the immediately preceding peak and on the length of the period between detections of the peaks. The device thereby determines the target wheel r.p.m. by subtracting a deceleration value, obtained as a function of the determined rate of deceleration, from the wheel r.p.m. determined at the time of detecting of the peaks of the coefficient of friction.
