An anti-skid control system for motor vehicles is disclosed wherein in case the wheel speed is equal to or lower than a minimum speed which is detectable by a microcomputer, the wheel speed is set at a predetermined threshold speed level between the minimum speed and zero, thereby preventing reduction of brake pressure from being started when the wheel is lower than the threshold speed. The anti-skid control system may also be designed such that a computed vehicle speed is set up which is approximate to the real vehicle speed; a reference speed is also set up on the basis of the computed vehicle speed in such a manner that it is lower by a predetermined amount than and follows the computed vehicle speed with such a speed difference; when the wheel speed becomes equal to or lower than a minimum speed which is detectable by a microcomputer, the wheel speed is set at a predetermined threshold speed level between the minimum speed and zero; and if a brake pressure reducing condition is prevailing at a point of time when the reference speed becomes equal to the threshold speed, then such a condition is released.

An anti-skid control system for a motor vehicle, comprising: means for providing a reference wheel speed which has a predetermined relationship to an actual wheel speed of the vehicle being decelerated; means for providing a system speed which coincides with the actual wheel speed except when the actual wheel speed becomes equal to or lower than a minimum speed detectable by a microcomputer; means for reducing brake pressure when said reference wheel speed and said system speed become equal to each other, to thereby cause the actual wheel speed to be changed from deceleration to acceleration; and means for changing said system speed to a predetermined threshold speed between said minimum speed and zero when said actual wheel speed becomes equal to or lower than said minimum speed, to thereby end reducing the brake pressure when the actual wheel speed is lower than said threshold speed.
