Abstract

L'invention concerne un procédé d'utilisation d'un entraînement hybride d'un véhicule comportant au moins un moteur à combustion interne et au moins deux moteurs électriques, le moteur à combustion interne fonctionnant avec une combustion homogène dans au moins une zone de fonctionnement. Selon l'invention, l'entraînement hybride fonctionne sélectivement dans le mode série ou le mode parallèle. Lorsque l'entraînement hybride ne doit fournir qu'un faible travail dynamique, celui-ci fonctionne en mode série, et en mode parallèle en cas de travail dynamique élevé à fournir. Lorsque le travail dynamique à fournir est supérieur à la limite dynamique du moteur à combustion interne, ledit travail est compensé temporairement au moyen d'au moins un moteur électrique.
