Abstract

Selon un procédé d'exploitation d'une chaîne de transmission de véhicule automobile, qui comporte un moteur à combustion (12) en tant qu'entraînement, dont l'arbre d'entraînement peut être couplé par le biais d'un dispositif d'accouplement (21, 22) à un arbre de sortie (15), dans lequel la chaîne de transmission de véhicule automobile présente un moteur électrique (13) en liaison d'entraînement avec l'arbre de sortie qui peut être au moins exploité comme générateur, l'arbre de sortie est entraîné à l'aide du moteur à combustion. Le dispositif d'accouplement est ouvert et le moteur à combustion est mis hors circuit. Le moteur électrique est entraîné pendant la séquence d'arrêt du moteur de combustion par l'arbre de sortie encore en mouvement et un couple de freinage est exercé sur l'arbre de sortie par la production d'énergie électrique par le moteur électrique. Un signal de vitesse de rotation du moteur à combustion est saisi et la présence d'oscillations pendulaires dans le signal de vitesse de rotation est détectée. En cas d'apparition d'oscillations pendulaires, le dispositif d'accouplement est activé de manière régulée de sorte qu'un couple de rotation opposé aux oscillations pendulaires est transmis à l'arbre d'entraînement du moteur à combustion par le biais du dispositif d'accouplement. Le couple de freinage du moteur électrique est réduit en fonction du couple de rotation transmis à l'arbre de sortie par le biais du dispositif d'accouplement.
