Abstract:
(EN) One aspect of the invention relates to a method for shifting a transmission, which can be shifted into different gears, for a motor vehicle, wherein the motor vehicle comprises an electric machine which is connected to the input of a transmission via a clutch. According to the method, after a shifting-up command, for shifting the transmission into a higher gear, has been received, the clutch between the electric machine and the transmission is opened, the rotational speed of the electric machine is reduced, the shifting operation is carried out in the transmission, and the clutch is closed again. The method according to the invention is characterized in that it is decided whether the reduction in the rotational speed of the electric machine is to be implemented by operating said electric machine in a generator-type, first braking mode, or by operating said electric machine in a second braking operating mode with increased power loss.
(FR) Un aspect de l'invention porte sur un procédé pour assurer le passage de rapports d'une boîte de vitesses d'un véhicule à moteur, pouvant être commutée dans différents rapports, ledit véhicule à moteur comprenant un moteur électrique qui est relié à l'entrée d'une boîte de vitesses par l'intermédiaire d'un embrayage. Selon le procédé, après réception d'une commande de passage montant de rapport pour assurer le passage de la boîte de vitesses à une vitesse supérieure, l'embrayage est ouvert entre le moteur électrique et la boîte de vitesses, le régime du moteur électrique est réduit, le passage de vitesse s'effectue dans la boîte de vitesses et l'embrayage est à nouveau fermé. Le procédé selon l'invention se caractérise en ce qu'il est décidé si la réduction du régime du moteur électrique doit intervenir par son fonctionnement dans un premier mode freinage de type générateur ou par son fonctionnement dans un second mode freinage, avec une puissance dissipée augmentée.
(DE) Ein Aspekt der Erfindung betrifft ein Verfahren zum Schalten eines in unterschiedliche Gänge schaltbaren Getriebes für ein Kraftfahrzeug, wobei das Kraftfahrzeug eine elektrische Maschine umfasst, die über eine Kupplung mit dem Eingang eines Getriebes verbunden ist. Gemäß dem Verfahren wird nach Entgegennahme eines Hochschalt-Kommandos zum Schalten des Getriebes in einen höheren Gang die Kupplung zwischen elektrischer Maschine und Getriebe geöffnet, die Drehzahl der elektrischen Maschine reduziert, die Schaltung im Getriebe durchgeführt und die Kupplung wieder geschlossen. Das erfindungsgemäße Verfahren kennzeichnet sich dadurch, dass entschieden wird, ob die Reduktion der Drehzahl der elektrischen Maschine durch deren Betreiben in einer generatorischen, ersten Bremsbetriebsart oder durch deren Betreiben in einer zweiten Bremsbetriebsart mit erhöhter Verlustleistung umgesetzt werden soll.
