Abstract

Selon la présente invention, dans un dispositif de commande pour un véhicule hybride qui est pourvu d'un moteur et d'un groupe électrogène et qui se déplace tout en chargeant une batterie avec la puissance électrique générée par le groupe électrogène au moyen du couple moteur, lorsque la quantité de charge dans la batterie est égale ou supérieure à une valeur prédéfinie, le couple généré par le groupe électrogène est augmenté si un couple d'entraînement demandé n'est pas supérieur à un couple prédéfini. Si le couple d'entraînement demandé est supérieur au couple prédéfini, le couple généré par le groupe électrogène est diminué.
