Abstract

La présente invention concerne un procédé de commande dune transmission automatique équipant un véhicule en situation de montée. Elle concerns aussi un dispositif de commande dune transmission automatique équipant un véhicule en situation de montée. Particulibrement en situation de montée, la transmission automatique se place dans un état instable dit de pompage. Pour y remédier, méme si d'autres paramétres conduisent á un phénoméne de pompage, I'invention définit des moyens pour prendre en compte 1'environnement du véhicule et décider d'un changement de rapport de transmission selon la situation de montée.
