ABSTRACT:
A wheel slip control system for motor vehicles is provided wherein when a given driven vehicle wheel spins this vehicle wheel is braked, and wherein when both driven wheels spin, the engine power is reduced. A spinning of the driving wheels is obtained by means of rotational speed sensors and a signal is fed to an electronic control unit. When a slip signal is present as a result of the exceeding of a differential speed threshold value between the driven and the non-driven vehicle axle, the engine power is controlled downward by the electronic control unit during the duration of the spin signal by means of a control element. When the slip signal drops, the engine power is again controlled upward to the desired gas pedal value set by the driver. In order to avoid drive train vibrations, the electronic control unit generates an output signal which actuates a time function element to prolong the activating of the downward-controlling control element beyond the duration of the last spin signal when spin signals occur at intervals within a certain limit time.
