Zusammenfassung:A system and method is provided for controlling an electric machine rotatably coupled to a rotatable shaft of an electronically-controlled one of a turbocharger and an exhaust-driven turbo supercharger fluidly coupled to an exhaust duct of an internal combustion engine. An operating temperature of a component of the engine is determined or estimated an operating temperature of a component of the engine or coupled to the engine, which is compared to a threshold temperature. The electric machine is controlled to operate as a motor in response to the determined or estimated temperature of the component being below a threshold temperature.
