Die Erfindung betrifft ein Antriebssystem zur Verwendung in einem Hybridfahrzeug, das einen Verbrennungsmotor, einen elektrischen Motor/Generator, der im Betrieb mit dem Verbrennungsmotor und einem elektrischen Speichermedium gekoppelt ist, und einen Antriebssystem-Controller zum Betätigen des Antriebssystems umfasst. Der Antriebssystem-Controller verändert die Betriebszustände des elektrischen Motor/Generator-Systems in Abhängigkeit von den Betriebszuständen des Fahrzeugs. Der Antriebssystem-Controller verändert die Betriebszustände des elektrischen Motors/Generators während einer Anlasssequenz des Verbrennungsmotors. A propulsion system for use in a hybrid vehicle, the propulsion system includes an internal combustion engine, an electric motor/generator operatively coupled to the internal combustion engine, an electric storage medium, and a propulsion system controller for actuating the propulsion system. The propulsion system controller varies the operating conditions of the electric motor/generator system in response to operating conditions of the vehicle. The propulsion system controller further varies the operating conditions of the electric motor/generator during an engine cranking sequence.
