Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betrieb eines Hybridantriebes (1 ) eines Fahrzeuges, mit einem Antriebsstrang (2), der einen Verbrennungsmotor (3), wenigstens eine elektrische Maschine (5) sowie ein Lastschaltgetriebe (7) aufweist, wobei der Verbrennungsmotor (3) aus rein elektromotorischer Fahrt während einer Lastschaltung startbar ist. Um einen zuverlässigen Startablauf und gleichzeitig einen hohen Betriebskomfort sicherzustellen, wird ein Schlupfzeitraum, in dem sich wenigstens ein Lastschaltelement des Lastschaltgetriebes (7) während einer Lastschaltung in Schlupf befindet, zumindest bei einem signalisierten Start des Verbrennungsmotors (3) unter Berücksichtigung eines zeitlichen Startverlaufs des Verbrennungsmotors (3) eingestellt. Bei einer Vorrichtung zur Durchführung des Verfahrens sind Mittel zur Erfassung und zeitvariablen Einstellung eines Schlupfes wenigstens eines Lastschaltelementes des Lastschaltgetriebes (7) vorgesehen.
