Zusammenfassung:A method of controlling a power inverter coupled to an electric motor in a vehicle powertrain having an engine is provided. The method includes generating a voltage waveform signal and a switching frequency signal for the inverter via a controller. At least one of the voltage waveform signal and the switching frequency signal is at least partially based on at least one commanded engine operating parameter. For example, the engine on/off state, engine torque, and engine speed can be considered. A vehicle having a controller configured to implement the method is also provided.
