Abstract
An automatic antilock control system for vehicles comprises a sensor which determines the presence of a tendency of a wheel to lock, a brake pressure open loop control device for varying the brake pressure at the said wheel and controlled by an evaluation circuit responsive to the sensor, the evaluation circuit including switch apparatus for producing open loop control signals which achieve a steep brake presence variation during an antilock control operation and thereafter achieve a further slower pressure variation, and open loop control apparatus for varying the duration of the pressure variation in dependence on the duration of the steep pressure variation of the previous cycle.
