A method for operating a drive motor which is coupled to at least one wheel of a vehicle via a drive train. The drive motor is controlled using a dynamic model of the drive train. The model maps a relationship between a drive torque transmitted via the drive train and a deformation of the drive train.

Method and motor controller for operating a drive motor of a vehicle

The invention relates to a control device for a voltage transformer of an electrically operated vehicle, which voltage transformer feeds an n-phase electric machine, n&#x3e;1. The control device comprises an observer unit, which is designed to determine a present rotational speed of the electric machine and a present output current of the voltage transformer, a computing unit, which is coupled to the observer unit and which is designed to compute an instantaneous wheel speed of the wheels of the vehicle in dependence on the determined present rotational speed, and a slip control unit, which is coupled to the computing unit and which is designed to at least temporarily apply a current correction amount to the output current of the voltage transformer if the present change of the wheel speed of the wheels exceeds a first predetermined threshold value.
