Abstract:
In order to determine a drive force (FAct) produced by an electric motor, the motor current (Ia) supplied to the electric motor (10) from a power supply source (32) is measured and a force is calculated from this; in addition, the motor voltage (UBat) applied to the electric motor (10) is measured, and drive force fluctuations which result from voltage fluctuations that occur during operation of the power supply source are compensated for, with at least one compensation force component being determined which is based on the measured motor voltage (UBat), including voltage fluctuations.
