An anti-skid control system for use in a motor vehicle which controls a braking pressure for a wheel of the motor vehicle to keep a slip of the wheel to an appropriate state by alternately performing a pressure-increasing operation and a pressure-maintaining operation in accordance with a slipping state of the wheel. The system first detects a slipping state of the wheel before performing the pressure-increasing operation on the basis of a vehicle speed and a wheel speed and then detects a slipping state of the wheel when a predetermined time period is elapsed from the pressure-increasing operation in a state that the braking pressure is maintained after the completion of the pressure-increasing operation so as to calculate a variation of the slipping state of the wheel on the basis of the detection results. Further, the system adjusts the ratio of a time period for the pressure-increasing operation to a time period for the pressure-maintaining operation so that the ratio becomes smaller as the variation of the slipping state becomes greater. This arrangement allows the wheel slipping state to be accurately detected without including errors due to the braking pressure increasing operation, thereby quickly increasing the braking pressure to an appropriate value.
An anti-skid control system for use in a motor vehicle which controls a braking pressure for a wheel of said motor vehicle to keep a slip of said wheel to an appropriate state, said system being arranged to increase said braking pressure by alternately performing a pressure-increasing operation and a pressure-maintaining operation in accordance with a slipping state of said wheel, said system comprising:
