Abstract

L'invention concerne un procédé et un dispositif pour faire fonctionner un véhicule automobile (2) à entraînement hybride, ledit véhicule étant constitué d'un moteur à combustion interne (3) et d'un moteur électrique (4) qui agissent tous les deux sur une chaîne cinématique hybride (1) commune et le moteur à combustion interne (3) fonctionnant au moins par intermittence en mode mélange air/carburant enrichi pour le fonctionnement des éléments d'un système de retraitement des gaz d'échappement (20), ou fonctionnant en mode recirculation des gaz d'échappement pour faire baisser la température des gaz d'échappement. Lorsqu'il se produit une augmentation de la demande de charge pour le moteur à combustion interne (3) pendant la phase du fonctionnement en mode mélange air/carburant enrichi ou pendant la phase du fonctionnement en mode recirculation des gaz d'échappement, le couple (MD_VKM) du moteur à combustion interne (3) est maintenu constant et, en raison de l'augmentation de la demande de charge, le couple supplémentaire nécessaire est appliqué exclusivement par le moteur électrique (4).
