Abstract

L’invention concerne un procédé de pilotage d’une boîte de vitesses (4) pour un véhicule automobile, ladite boîte de vitesses (4) comportant : - un premier arbre d’entrée (7) et un deuxième arbre d’entrée (8) qui sont respectivement associés à un premier embrayage (9) et à un deuxième embrayage (10) ; - un arbre de sortie (13) ; - un premier train d’engrenage (19) qui comporte un élément de connexion/déconnexion (16) qui est configuré pour accoupler en rotation le premier arbre d’entrée (7) à l’arbre de sortie (13) ; - un deuxième train d’engrenage (20) qui accouple en rotation le deuxième arbre d’entrée (8) à l’arbre de sortie (13), le procédé de pilotage comportant : - déterminer une première variable Ω représentative de la vitesse de rotation de l’arbre de sortie (13) ; - déplacer l’élément de connexion/déconnexion (16) de son état déconnecté vers son état connecté lorsque la première variable est inférieure à un premier seuil ; et - déplacer l’élément de connexion/déconnexion (16) de son état connecté vers son état déconnecté lorsque la première variable Ω est supérieure à un deuxième seuil, ledit deuxième seuil étant supérieur au premier seuil.
