Abstract: The anti-wheel-lock control system has a wheel speed transducer (1), an evaluation circuit (3), and a braking pressure control device (4, 5).Particularly in commercial vehicles and at low speed, the vehicle wheel may exhibit frictional oscillations; these frictional oscillations appear as rapidly changing speed signals when sensed by the value transducer (1), which simulate sudden high wheel speed. The invention addresses the problem of eliminating these disturbances. The changes in the speed signals are physically impossible, and the disturbances are eliminated by a circuit (15, 16, 27, 28, 29) which recognizes physically impossible changes in the wheel speed by comparing the actual speed signals with a simulation threshold at which changes in speed are physically impossible.
