Abstract

L'invention concerne un procédé pour faire fonctionner une chaîne cinématique d'un véhicule automobile. Lors du démarrage du moteur à combustion interne (2) par entraînement à l'aide du moteur électrique (3), l'embrayage (4) monté entre le moteur à combustion interne (2) non allumé et le moteur électrique (3) qui délivre un couple constant est fermé en patinant de telle sorte que le couple d'embrayage transmis par l'embrayage augmente linéairement dans le temps entre une première valeur initiale MK,A1 et une première valeur finale MK,E1. Lorsque le moteur à combustion interne non allumé commence alors à tourner, le couple de décollage MK,LOS du moteur à combustion interne est déterminé à partir du couple d'embrayage où le moteur à combustion interne non allumé commence à tourner, et si le moteur à combustion interne non allumé ne commence alors pas à tourner, l'embrayage (4) monté entre le moteur à combustion interne non allumé et le moteur électrique est fermé en patinant de telle sorte que le couple d'embrayage transmis par l'embrayage augmente linéairement dans le temps à partir d'une deuxième valeur initiale MK,A2 jusqu'à ce que le moteur à combustion interne non allumé commence à tourner, le couple de décollage MK,LOS du moteur à combustion interne étant déterminé à partir du couple d'embrayage où le moteur à combustion interne commence à tourner.
