Abstract

The disclosure is directed to a method for slip control of a vehicle wheel driven via an electric drive. The method includes at least the following steps: driving the electric drive of the vehicle wheel using an actual drive torque in a torque control in a torque control step, determining a wheel speed and a wheel slip of the vehicle wheel and evaluating the wheel slip by way of an instability criterion as to whether an instability exists, upon recognizing an instability, direct or indirect transition in a slip control of the wheel slip to a setpoint slip by driving the electric drive, determining whether an end criterion for ending the slip control is satisfied; and, if the end criterion is satisfied, returning to the torque control in the torque control step.
