Abstract
An anti-skid brake control system for a motor vehicle includes wheel sensors for producing signals representative of the rotational speed of each road wheel; an evaluation circuit responsive to the wheel speed signals for determining a reference speed that approaches the speed of the vehicle and for producing brake pressure control signals, in dependence upon the reference speed and the road wheel speeds; and a brake pressure controller responsive to the brake pressure control signals for varying the brake pressure applied to the road wheels. The evaluation circuit includes means for determining the vehicle speed from the average increase of the reference speed and this vehicle speed, so determined, is used to determine an increase in the value of the reference speed during periods of braking instability.
