Abstract
A method for determining phase currents for current control of an electric machine of a drive system for a motor vehicle is provided. Measured characteristics of the phase currents that are supplied to at least three phases of a set of phases of the electric machine and that are measured by at least three phase current sensors of a set of phase current sensors of the drive system are received. Zero crossings in the at least three measured phase current sensor-specific characteristics are identified, a phase current value of at least one other characteristic is determined, per characteristic, for at least one zero crossing. The phase current values are used for determining a characterization value, describing a gain factor of each phase current sensor, for the respective phase current sensor, and the phase currents for the current control are determined based on the characterization values of the phase current sensors.
