Method of controlling motor vehicle automatic transmission during periods of stoppage involves maintaining pressure in transmission and positioning transmission in optimum position for restarting using electric motor

The motor vehicle has an automatic transmission which is controlled to maintain its operating pressure after the engine is stopped. The retained pressure holds the transmission clutch and brakes in an operating condition while the engine is stopped to ensure they are operational during the next star...

Zusammenfassung:	The motor vehicle has an automatic transmission which is controlled to maintain its operating pressure after the engine is stopped. The retained pressure holds the transmission clutch and brakes in an operating condition while the engine is stopped to ensure they are operational during the next starting phase. The automatic transmission (3) can be released from the engine (2) during the stopped phase and operated again by an electric motor (6). The starter motor of the engine can be used for this. Il est décrit un procédé de fonctionnement d'un véhicule automobile, comportant au moins une transmission automatique et un moteur à combustion interne, en fonctionnement marche/ arrêt. La pression de système régnant dans la transmission automatique (3) est maintenue pendant la phase d'arrêt du moteur à combustion interne (2) à un niveau suffisant pour placer les éléments d'embrayage-accouplement et de freinage de la transmission automatique en une position et/ ou les maintenir au moins à peu près dans cette position, nécessaire pour le démarrage du véhicule automobile, après la phase d'arrêt.
