摘要：
The invention relates to a method for determining a time mean of a pulse width-modulated current of an electric motor of a motor vehicle. According to said method, a plurality of measuring values of a measuring variable that has a known correlation with the momentary current flowing through the electric motor is detected at several time intervals within the period of pulse width modulation (64) and a time mean of the current is calculated on the basis of these measuring values (74, 76).
