Title

(DE) SYSTEM ZUM ANSTEUERN EINER KOMPONENTE EINES GETRIEBES EINES FAHRZEUGES UNTER BERÜCKSICHTIGUNG EINES FLUIDVERLUSTES

(EN) SYSTEM FOR CONTROLLING A COMPONENT OF A GEARBOX IN A VEHICLE BY TAKING INTO ACCOUNT FLUID LOSS

(FR) SYSTEME DE COMMANDE D'UN COMPOSANT D'UNE BOITE DE VITESSES D'UN VEHICULE EN FONCTION D'UNE PERTE FLUIDIQUE

Abstract

(DE) Es wird ein System zum Ansteuern einer Komponente eines Getriebes eines Fahrzeuges, insbesondere einer Kupplung, über eine hydraulische Übertragungsstrecke mit einer Getriebesteuerung und einer Motorsteuerung vorgeschlagen, bei dem ein Fluidverlust der Übertragungsstrecke erkennbar ist und danach der Motor und/oder das Getriebe mittels der Getriebesteuerung und/oder Motorsteuerung geeignet ansteuerbar ist.

(EN) The invention relates to a system for controlling a component of a gear in a vehicle, especially a clutch, by means of a hydraulic transmission link comprising a gearbox control unit and a motor control unit, whereby a loss in fluid in the transmission link can be detected, whereupon the motor and/or the gearbox can be suitably controlled by means of the gearbox control and/or motor control unit.

(FR) L'invention concerne un système de commande d'un composant d'une boîte de vitesses d'un véhicule, en particulier d'un embrayage, par un ensemble de transmission hydraulique. Ce système comprend une commande de boîte de vitesses et une commande de moteur. Selon cette invention, une perte fluidique de l'ensemble de transmission peut être détectée puis le moteur et/ou la boîte de vitesses peut être commandé(e) de façon appropriée au moyen de la commande de boîte de vitesses et/ou de la commande du moteur.
