Abstract:
(EN) The invention relates to a method for determining a coupling state (128a - 138a) of a drive train (2) of a motor vehicle (1) coupled to a clutch (4) on an internal combustion engine (112). Said method comprises the following steps: detecting the temporal course of a rotational speed (n) correlated to the rotational speed (nΒΚΜ) of the internal combustion engine (112); detecting at least one speed pattern (128 -138), produced by the internal combustion engine (112), from the temporal course of the rotational speed (nΒΚΜ), that has an oscillation (O) with at least one amplitude (A) superimposed over the temporal course of the mean value (DMD) of the rotational speed (nΒΚΜ), then it is closed in a coupling state (128a - 138a) when within a time interval (Δt), a characteristic change of the rotational speed (nΒΚΜ) and a characteristic behavior of the amplitudes (A) is detected. Furthermore, the invention relates to a corresponding computing unit (118) which is configured to carry out the method, to an electric machine comprising the computing unit and to a corresponding computer program for carrying out said method.
(FR) L’invention concerne un procédé pour identifier un état d'embrayage (128a à 138a) d’une chaîne de transmission (2) d’un véhicule à moteur (1) couplée à un moteur à combustion interne (112) par un embrayage (4), comprenant les étapes suivantes : détermination de la courbe temporelle d’un régime (n) corrélé au régime (nΒΚΜ) du moteur à combustion interne (112), détermination, à partir de la courbe temporelle du régime (nΒΚΜ), d’au moins un modèle de régime (128 à 138) produit par le moteur à combustion interne (112) qui présente une oscillation (O) ayant au moins une amplitude (A), superposée à la courbe temporelle de la valeur moyenne (DMD) du régime (nΒΚΜ). Un état d’embrayage (128a à138a) est déduit de la détection de modifications caractéristiques du régime (nΒΚΜ) et d’un comportement caractéristique des amplitudes (a9) dans un intervalle de temps (Δt). En outre, l'invention concerne une unité de calcul (118) correspondante laquelle est conçue pour mettre en œuvre ledit procédé, une machine électrique comportant ladite unité de calcul ainsi qu’un programme informatique correspondant pour la mise en oeuvre du procédé.
(DE) Die Erfindung betrifft ein Verfahren zum Ermitteln eines Kupplungszustands (128a bis 138a) eines mit einer Kupplung (4) an eine Brennkraftmaschine (112) gekoppelten Antriebstrangs (2) eines Kraftfahrzeugs (1), aufweisend die Schritte: Erfassen des zeitlichen Verlaufs einer mit der Drehzahl (nΒΚΜ) der Brennkraftmaschine (112) korrelierten Drehzahl (n), Erfassen zumindest eines durch die Brennkraftmaschine (112) bewirkten Drehzahlmusters (128 bis 138) aus dem zeitlichen Verlauf der Drehzahl (nΒΚΜ), das eine dem zeitlichen Verlauf des Mittelwerts (DMD) der Drehzahl (nΒΚΜ) überlagerte Oszillation (O) mit zumindest einer Amplitude (A) aufweist, wobei dann auf einen Kupplungszustand (128a bis 138a) geschlossen wird, wenn innerhalb eines Zeitintervalls (Δt) eine charakteristische Veränderung der Drehzahl (nΒΚΜ) und ein charakteristisches Verhalten der Amplituden (A) erkannt wird. Des Weiteren betrifft die Erfindung eine entsprechende Recheneinheit (118), die zur Durchführung des Verfahrens eingerichtet ist, eine die Recheneinheit aufweisende elektrische Maschine, sowie ein entsprechendes Computerprogramm zur Durchführung des Verfahrens.
