ABSTRACT:
The invention is directed to an anti-skid control system for controlling a braking force applied to a road wheel with a hydraulic braking pressure supplied to a wheel brake cylinder through pressure control means. On the basis of a wheel speed of the road wheel detected by detecting means, a wheel acceleration and an estimated vehicle speed are calculated. A difference between the wheel speed and the estimated vehicle speed is calculated, and an integrated value thereof during a certain period is obtained. Then, a wheel lock rate indicative of a locking condition of the road wheel is set on the basis of the integrated value at least. Means is provided for setting an increasing time for increasing the hydraulic braking pressure and a holding time for holding it as it is with a proportion therebetween determined in response to a relationship between the wheel acceleration and the wheel lock rate, or setting a decreasing time and the holding time as well. The pressure control means is arranged to alternately increase and hold the hydraulic braking pressure in response to the increasing time and holding time, or decrease and hold it as well.
