Abstract:
(EN) The invention relates to a method for operating a drive train of a motor vehicle, which drive train has at least one drive engine, a transmission device and at least one wheel which can be driven by the drive engine via the transmission device, in which method respective actuations are brought about by respective shifting elements of the transmission device, in order, as a result, to influence a transmission of a torque which is provided by the drive engine from the drive engine via the transmission device to the wheel, wherein - the torque which is provided by the drive engine is set as a function of a transmission function (20) which specifies a factor, by which the torque is to be multiplied, in order to calculate a wheel torque which results from the torque and the transmission and acts on the wheel; - respective parameters (10a-10e) are determined which characterize respective states of the respective shifting elements, which respective states result from the effect of the actuations; and - the transmission function (20) is monitored in a manner which is dependent on the determined parameters (10a-10e).
(FR) Procédé de fonctionnement d’une chaîne cinématique d’un véhicule à moteur, en particulier d’un véhicule automobile L’invention concerne un procédé de fonctionnement d’une chaîne cinématique d’un véhicule à moteur, comprenant au moins un moteur d’entraînement, un dispositif de transmission et au moins une roue pouvant être entraînée par le moteur d’entraînement via le dispositif de transmission, dans lequel des actionnements respectifs d’éléments de commutation respectifs du dispositif de transmission sont déclenchés afin d’influencer le transfert d’un couple fourni par le moteur d’entraînement du moteur d’entraînement à la roue via le dispositif de transmission, - le couple fourni par le moteur d‘entraînement étant réglé en fonction de la fonction de transfert (20), laquelle indique un facteur par lequel le couple doit être multiplié pour calculer un couple de roue résultant du couple et du transfert et agissant sur la roue ; - des paramètre respectifs (10a-10e) étant déterminés, qui caractérisent des états des éléments de commutation respectifs résultant du déclenchement des actionnements ; et – la fonction de transfert (20) étant surveillée en fonction des paramètres (10a-10e) déterminés.
(DE) Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs, insbesondere eines Kraftwagens Die Erfindung betrifft ein Verfahren zum Betreiben eines wenigstens einen Antriebsmotor, eine Getriebeeinrichtung und wenigstens ein über die Getriebeeinrichtung von dem Antriebsmotor antreibbares Rad aufweisenden Antriebsstrangs eines Kraftfahrzeugs, bei welchem jeweilige Betätigungen von jeweiligen Schaltelementen der Getriebeeinrichtung bewirkt werden, umdadurcheine Übertragung eines von dem Antriebsmotor bereitgestellten Drehmoments von dem Antriebsmotor über die Getriebeeinrichtung auf das Rad zu beeinflussen, wobei - das von dem Antriebsmotor bereitgestellte Drehmoment in Abhängigkeit von einer Übertragungsfunktion (20) eingestellt wird, welche einen Faktor angibt, mit welchem das Drehmoment zu multiplizieren ist, um ein aus dem Drehmoment und aus der Übertragung resultierendes und an dem Rad wirkendes Raddrehmoment zu berechnen; - jeweilige Parameter (10a-10e) ermittelt werden, welche jeweilige, aus dem Bewirken der Betätigungen resultierende Zustände der jeweiligen Schaltelemente charakterisieren; und - die Übertragungsfunktion (20) in Abhängigkeit von den ermittelten Parametern (10a-10e) überwacht wird.
