VEHICULE A MOTEUR AVEC BOITES DE VITESSES A COMMUTATION AUTOMATIQUE ENTRE LES MODES D'EXPLOITATION.

摘要

A motor vehicle has a transmission with an automatic operating mode in which the transmission ratio is changed automatically by a control device and a manual operating mode in which the transmission ratio is changed by the driver by means of a ratio-selector device. The control device automatically switches from the manual to the automatic mode, e.g., when the driver makes or answers a call on a mobile telephone.
