Abstract
Method for determining a measuring offset of a rotor position sensor () assigned to a rotor () of an electric machine () comprising stator windings that are supplied by an inverter () converting a voltage at a DC link capacitor () into an AC current, wherein a candidate value for the measuring offset is determined, comprising the following steps: —controlling a power unit () of the inverter () to provide the current based on rotor position information () measured by the rotor position sensor () to the stator windings such that the DC link capacitor () of the inverter () is actively discharged, —evaluating a plausibility of the candidate value for the measuring offset based on a voltage of the DC link capacitor () detected while the power unit () is controlled to actively discharge the DC link capacitor (), and —providing the candidate value as determined measuring offset, if a result of the evaluation is positive.
