Title
(DE) VERFAHREN ZUM BETREIBEN EINES ANTRIEBSSTRANGS
(EN) METHOD FOR OPERATING A DRIVE TRAIN
(FR) PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER UNE CHAÎNE CINÉMATIQUE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs, wobei der Antriebsstrang ein Antriebsaggregat, ein Getriebe und eine zwischen das Antriebsaggregat und das Getriebe geschaltete Anfahrkupplung umfasst, wobei der Antriebsstrang beim Anrollen im Schubbetrieb und beim Ausrollen im Schubbetrieb derart betrieben wird, dass ein Sollwert für die Position der Anfahrkupplung abhängig von einer Getriebeeingangsdrehzahl ermittelt wird, dass der Sollwert für die Position der Anfahrkupplung mit einem entsprechenden Istwert verglichen wird, und dass in einem Regler auf Basis der Abweichung zwischen dem Sollwert und dem Istwert eine Stellgröße zur Verstellung der Anfahrkupplung generiert wird. Der Sollwert für die Position der Anfahrkupplung für das Anrollen und für das Ausrollen wird derart ermittelt, dass bei einem definierten Wert der Getriebeeingangsdrehzahl für das Anrollen ein anderer Sollwert für die Position der Anfahrkupplung ermittelt wird als für das Ausrollen.
(EN)
The invention relates to a method for operating a drive train, wherein the drive train comprises a drive aggregate, a gearbox, and a starting clutch connected between the drive aggregate and the gearbox, wherein the drive train is operated when starting to roll during coasting mode and when coasting during coasting mode such that a target value for the position of the starter clutch is determined as a function of a gearbox input speed, that the target value for the position of the starter clutch is compared to a corresponding actual value, and that an adjustment parameter for adjusting the starter clutch is generated in a controller on the basis of the difference between the target value and the actual value. The target value for the position of the starter clutch for starting to roll and for coasting is determined such that, for a defined value of the gearbox input speed, a different target value is determined for the position of the starter clutch for starting to roll than for coasting.
(FR)
L'invention concerne un procédé permettant de faire fonctionner une chaîne cinématique, la chaîne cinématique comprenant un groupe moteur, une boîte de vitesses, et un embrayage de démarrage monté entre le groupe moteur et la boîte de vitesses, la chaîne cinématique fonctionnant, lors du démarrage, en poussée, et pour l'arrêt, en décélération, de façon qu'une valeur de consigne soit déterminée pour la position de l'embrayage de démarrage, en fonction d'une vitesse de rotation d'entrée de la boîte de vitesses, de façon que la valeur de consigne pour la position de l'embrayage de démarrage soit comparée avec une valeur réelle correspondante, et que, dans un régulateur, une valeur de réglage établie sur la base de l'écart entre la valeur de consigne et la valeur réelle, soit générée en vue du réglage de l'embrayage de démarrage. La valeur de consigne pour la position de l'embrayage de démarrage pour le démarrage et pour l'arrêt est déterminée de façon que pour une valeur définie de la vitesse de rotation d'entrée de la boîte de vitesses, on détermine pour le démarrage, pour la position de l'embrayage d'entrée, une valeur de consigne autre que pour l'arrêt.
