Abstract: Die vorliegende Erfindung liefert ein Fahrzeug mit Hybridantrieb, das eine regenerative Leistungserzeugung unter Verwendung eines Elektromotors durchführen kann, ohne daß ein seltsames Gefühl beim Fahrer bewirkt wird. Eine Ausgleichskupplung, die in ihrer Kupplungskraft einstellbar ist, ist in einem Leistungsübertragungssystem, das dem Elektromotor und einer Brennkraftmaschine gemeinsam ist, angeordnet. Während eines Motorbremsbetriebes wird die Kupplungskraft der Ausgleichskupplung in einem halb gekuppelten Zustand gehalten, um die Drehung der Antriebsräder für eine regenerative Leistungserzeugung auf den Elektromotor zu übertragen. Ein Schleifen der Ausgleichskupplung wird verwendet, um eine Übertragung des Rotationswiderstandes des Elektromotors, der durch die regenerative Leistungserzeugung erhöht ist, an die Antriebsräder zu verhindern, um es zu ermöglichen, eine stabile Motorbremskraft ohne eine Drehmomentfluktuation zu erhalten.
