Abstract

The invention relates to an anti-locking wheel control system in which control signals for the variation of the brake pressure are derived from the rotary motion behavior of the vehicle wheels and in which a test circuit is provided, which initiates a test for at least one wheel brake when a signal appears which indicates a tendency toward locking, in which test the over-braked vehicle wheel enters a state of high slippage, whereby the test circuit determines how the wheel behaves at the given coefficient of friction between the road surfaces and the tire, and whereby on the basis of this determination, the test circuit either provides a state in which the brake pressure is regulated or else switches to a state in which the control is made ineffective for at least some of the wheel brakes.
