Title
(DE) VERFAHREN ZUM BETREIBEN EINES ANTRIEBSSTRANGS
(EN) METHOD FOR OPERATING A DRIVETRAIN
(FR) PROCÉDÉ POUR FAIRE FONCTIONNER UNE CHAÎNE DE TRANSMISSION
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Betreiben eines ein Automatgetriebe (2) und ein Antriebsaggregat (1) aufweisenden Antriebsstrangs, wobei zur Ausführung einer Schaltung, insbesondere einer Hochschaltung, eine zwischen das Automatgetriebe (2) und das Antriebsaggregat geschaltete Kupplung zuerst geöffnet und nach Ausführung der Schaltung geschlossen wird. Erfindungsgemäß wird ein Fahrzeuggeschwindigkeitsgradient oder ein Getriebeeingangsdrehzahlgradient oder ein Getriebeausgangsdrehzahlgradient oder ein Raddrehzahlgradient überwacht, wobei die Kupplung (4) nach Ausführung der Schaltung derart geschlossen wird, dass der überwachte Gradient innerhalb eines definierten Wertebereichs liegt oder einen definierten Wert annimmt.
(EN)
The invention relates to a method for operating a drivetrain which has an automatic transmission (2) and a drive unit (1), wherein to perform a shift, in particular an upshift, a clutch which is connected between the automatic transmission (2) and the drive unit is firstly opened and, after the shift is performed, is closed again. According to the invention, a vehicle speed gradient or a transmission input rotational speed gradient or a transmission output rotational speed gradient or a wheel rotational speed gradient is monitored, wherein after the shift is performed, the clutch (4) is closed in such a way that the monitored gradient lies within a defined value range or assumes a defined value.
(FR)
L'invention concerne un procédé pour faire fonctionner une chaîne de transmission présentant une boîte de vitesses automatique (2) et une unité d'entraînement (1). Pour effectuer un changement de vitesse, en particulier un passage à la vitesse supérieure, un embrayage monté entre la boîte de vitesses automatique (2) et l'unité d'entraînement est d'abord ouvert puis fermé, après le changement de vitesse. Conformément à l'invention, un gradient de vitesse du véhicule ou un gradient de la vitesse de rotation à l'entrée de la boîte de vitesses ou un gradient de la vitesse de rotation à la sortie de la boîte de vitesses ou un gradient de vitesse de rotation des roues est contrôlé, et l'embrayage (4) est fermé après le changement de vitesse de telle sorte que le gradient contrôlé se situe à l'intérieur d'une plage de valeurs prédéterminée ou adopte une valeur définie.
