Abstract
L'invention porte sur un procédé de détermination des points de synchronisation d'une boite de vitesses à double embrayage d'un véhicule, notamment automobile, et comprend notamment les étapes suivantes : • au moment où le point de synchronisation (120) est déterminé pour un rapport intermédiaire, déclenchement d'une temporisation d'une durée déterminée mémorisée dans le calculateur, • interruption du déplacement du manchon de synchronisation de ce rapport intermédiaire par l'actionneur à la fin de la temporisation, • retour du manchon de synchronisation de ce rapport intermédiaire par l'actionneur à sa position initiale neutre occupée avant son déplacement.
