Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben eines einen zu- und abschaltbaren Vierradantrieb (18) und wenigstens zwei miteinander kämmende Zahnräder (14, 16) aufweisenden Antriebsstrangs (10) eines Kraftwagens, bei welchem der Vierradantrieb (18) abgeschaltet wird, indem wenigstens eine Kupplung (12) des Antriebsstrangs (10) geöffnet wird, wobei ein aus dem Abschalten resultierender Anlagewechsel der Zahnräder (14, 16) mittels einer elektrischen Maschine (20) des Antriebsstrangs (20) aktiv abgebremst wird.
(EN) The invention relates to a method for operating a drive train (10) of a motor vehicle, said drive train comprising an engageable and disengageable four-wheel drive (18) and at least two intermeshing gears (14, 16), in which the four-wheel drive (18) is switched off by the opening of at least one clutch (12) of the drive train (10), wherein a change of engagement of the gears (14, 16) resulting from the switching off is actively braked by means of an electric machine (20) of the drive train (10).
(FR) L'invention concerne un procédé pour faire fonctionner une chaîne cinématique (10) d'un véhicule automobile, comprenant une transmission à quatre roues motrices (18) enclenchable et désenclenchable et au moins deux pignons (14, 16) s'engrenant l'un avec l'autre. Selon ledit procédé, la transmission à quatre roues motrices (18) est désenclenchée lorsqu'au moins un embrayage (12) de la chaîne cinématique est à l'état de désaccouplement, une modification d'appui des pignons (14, 16) résultant du désenclenchement étant activement freinée au moyen d'un moteur électrique (20) de la chaîne cinématique (10).
