Title
(DE) VERFAHREN ZUM BETREIBEN EINES HYBRIDANTRIEBSSTRANGS EINES FAHRZEUGS
(EN) METHOD FOR OPERATING A HYBRID DRIVE TRAIN OF A VEHICLE
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE CHAÎNE DE TRANSMISSION HYBRIDE D'UN VÉHICULE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Betreiben eines Hybridantriebsstrangs eines Fahrzeugs, bei dem ein Verbrennungsmotor (VM) und eine Elektromaschine (EM) je nach Betriebssituation einzeln oder zusammen antriebswirksam auf ein Fahrzeuggetriebe (GE) mit schaltbaren Übersetzungen einwirken. Zur Koordination von Schaltungen des Fahrzeuggetriebes (GE) und eines angeforderten Schleppstarts bzw. Zustarts des Verbrennungsmotors (VM) ist vorgesehen, dass bei einem ablaufenden Schaltvorgang des Fahrzeuggetriebes (GE) und dem Vorliegen einer Anforderung nach einem Schleppstart oder einem Zustart des Verbrennungsmotors (VM) in Abhängigkeit davon, ob der Schaltvorgang ein Hochschaltvorgang, ein Rückschaltvorgang, ein Zugschaltvorgang oder ein Schubschaltvorgang ist, sowie abhängig von der Art des angeforderten Starts des Verbrennungsmotors (VM) zunächst eine Prüfung dahingehend erfolgt, ob der Schaltvorgang ausgeführt, zumindest teilweise ausgeführt oder abgebrochen werden soll bevor der Schleppstart oder der Zustart durchgeführt wird.

(EN)
The invention relates to a method for operating a hybrid drive train of a vehicle in which an internal combustion engine (VM) and an electric machine (EM), individually or together depending on the operating situation, act in a driving fashion on a vehicle transmission (GE) with switchable transmission ratios. In order to coordinate shifting operations of the vehicle transmission (GE) and of a requested tow start or assisted starting of the internal combustion engine (VM) there is provision that during a running‑out shifting process of the vehicle transmission (GE) and the presence of a request for a tow start or assisted starting of the internal combustion engine (VM) it is firstly checked, depending on whether the shifting operation is a shifting up operation, a shifting down operation, a traction shifting operation or an overrun shifting operation as well as depending on the type of requested start of the internal combustion engine (VM), whether the shifting process is to be carried out, at least partially carried out or interrupted before the tow start or the assisted starting is carried out.

(FR)
L'invention concerne un procédé de fonctionnement d'une chaîne de transmission hybride d'un véhicule, dans lequel un moteur à combustion interne (VM) et un moteur électrique (EM) agissent seuls ou ensemble à des fins d'entraînement sur une boîte de vitesse de véhicule (GE) à rapports commutables, selon le type de fonctionnement. Pour coordonner les changements de rapport de la boîte de vitesses (GE) et un réaccouplement ou un redémarrage demandé du moteur à combustion interne(VM), un contrôle a tout d'abord lieu pour savoir si, lors d'un changement de rapport de la boîte de vitesses (GE) et en présence d'une demande de réaccouplement ou de redémarrage du moteur à combustion interne, le passage de vitesse doit être effectué, au moins partiellement effectué ou interrompu avant l'exécution du réaccouplement ou du redémarrage selon qu'il s'agit d'un passage à un rapport supérieur, d'un passage à un rapport inférieur, d'un changement de rapport en traction ou d'un changement de rapport en poussée et selon le type de démarrage demandé du moteur à combustion interne (VM).
