Abstract
The invention relates to current sensor diagnostics in an electric drive system. According to the invention, a net current is formed from the sensor values provided by the current sensors. If this net current deviates significantly from zero, a complex current sum can be calculated using the rotor angle of the electric machine. This complex current sum is based on the current RMS current in the electric drive system in order to indicate deviations in the current gain factors of the current sensors used.
