Title
(DE) VERFAHREN ZUM STEUERN EINES AUTOMATGETRIEBES
(EN) METHOD FOR CONTROLLING AN AUTOMATIC TRANSMISSION
(FR) PROCEDE POUR COMMANDER UNE TRANSMISSION AUTOMATIQUE
Abstract
(DE) Es wird ein Verfahren zum Steuern eines von einer Brennkraftmaschine angetriebenen Automatgetriebes vorgeschlagen, bei dem eine Schaltung von einem ersten in ein zweites Übersetzungsverhältnis als eine Zug-Hochschaltung erfolgt, indem eine erste Kupplung öffnet und eine zweite Kupplung schließt, und ein elektronisches Getriebe-Steuergerät über elektromagnetische Ventile den Druckverlauf der ersten und der zweiten Kupplung während des Schaltvorgangs steuert. Der Schaltvorgang ist dabei in verschiedene Schaltphasen unterteilt, wobei innerhalb der Gradient-Einstell- (GE), der Gleit- (GL), der Gradient-Abbau (GA) und der Schließphase (S) ein Motoreingriff durch eine Reduzierung des Motormoments erfolgt, indem ein Motoreingriffsfaktor (mdzegs) von dem Getriebe-Steuergerät an ein Motor-Steuergerät der Brennkraftmaschine übertragen wird.
(EN) The invention relates to a method for controlling an automatic transmission which is driven by an internal combustion engine. A shift from a first transmission ratio to a second transmission ratio occurs in the form of a pull upshift. A first coupling opens and a second coupling closes, and an electronic transmission control device controls the pressure characteristic of said first and said second coupling during the shifting operation by means of electromagnetic valves. This shifting operation is divided into various shifting phases, an engine intervention taking place in the gradient setting phase (SG), the sliding phase (SL), the gradient reduction phase (RG) and the closing phase (S), an engine torque being reduced by means of an engine intervention factor (mdzegs) being transferred from the transmission control device to an engine control device of the internal combustion engine.
(FR) L'invention concerne un procédé pour commander une transmission automatique qui est entraînée par un moteur à combustion interne. Un passage d'un premier rapport de démultiplication à un deuxième rapport de démultiplication se produit sous la forme d'une montée des vitesses en traction. Un premier embrayage s'ouvre et un deuxième embrayage se ferme, et un dispositif de commande de transmission électronique commande la caractéristique de pression du premier et du deuxième embrayage pendant le changement de vitesses, au moyen de soupapes électromagnétiques. Ce changement de vitesses est divisé en différentes phases, une intervention du moteur s'effectuant par une réduction de son couple à l'intérieur de la phase de réglage du gradient (GE), de la phase de glissement (GL), de la phase de réduction du gradient (GR) et de la phase de fermeture (S), et cela par le fait qu'un facteur d'intervention du moteur (mdzegs) est transmis du dispositif de commande de transmission à un dispositif de commande du moteur à combustion interne.
