Abstract
An anti-skid control system for a motor vehicle in which, when a wheel speed to be controlled and being decreased through buildup of brake pressure becomes equal to a reference speed, this equality is judged as a fulfillment of a brake pressure reduction starting condition, and thus reduction of the brake pressure is started. The highest wheel speed is detected and a computed vehicle speed is set up based on the highest wheel speed by having the increase and decrease of the highest wheel speed limited to a predetermined range. The computed vehicle speed and the wheel speed to be controlled are compared; and when the comparison indicates that the wheel speed to be controlled is equal to or higher than the computed vehicle speed, no reduction of the brake pressure is started irrespective of whether the brake pressure reduction starting condition is fulfilled.
