A Drive-slip control device for motor vehicles in which, when a driven vehicle wheel spins, this wheel is braked and wherein when both driven wheels spin, the engine power is additionally reduced. Spinning of the drive wheels is recognized by means of rotational-speed sensors and an electronic system and when a spin signal is present on account of a differential-speed threshold value between driven and non-driven vehicle axles being exceeded, the power of the engine is reduced in a controlled manner by the electronic system during the duration of the spin signal by means of a final control element. When the spin signal stops, the power of the engine is increased again in a controlled manner to the target value predetermined by the driver by means of the accelerator. However, when power is reduced by the driver during a control operation of the drive-slip control device, below the engine control target value predetermined by the electronic system of the drive-slip control device (during a gear shift) and when power is increased again (when the gear-shift operation is complete) provided this takes place within a predetermined time, only the value which was also present before the reduction of power is permitted again as maximum power.
