Abstract
A method for controlling the traction slip of driven wheels of a vehicle between the wheels and the carriageway, in the case of which a manipulated variable is calculated for a drive engine of the vehicle on the basis of a detection of the instantaneous wheel speed and the calculation of a desired wheel speed, the manipulated variable being formed by an upper limit value for the rotational speed of the drive engine, characterized in that the instantaneous transmission ratio is calculated on the basis of the instantaneous rotational speed of the drive engine and the instantaneous wheel speed, and the upper limit value for the rotational speed of the drive engine is calculated from the desired wheel speed and the instantaneous transmission ratio.
