Abstract
An apparatus for measuring the wheel speed for an anti-skid control system of a motor vehicle, comprising a sensor for generating a pulse signal, the cycle of which corresponds to the rotational speed of the wheel. The wheel speed signal is provided in every control cycle having a constant time. If the wheel speed is not provided because the rotational speed of the wheel is low, the anti-skid control is performed in accordance with a compensated wheel speed calculated on the basis of the wheel speed measured immediately beforehand.
