Abstract

Die Erfindung betrifft ein Verfahren zur Diagnose einer nicht trennenden Kupplung (4,7) in einem Kraftfahrzeug, welche im geschlossenen Zustand eine Drehbewegung einer Antriebseinheit (1) auf ein Getriebe (3) weiterleitet, wobei das Getriebe die Drehbewegung an die Antriebsräder (12,13) des Kraftfahrzeuges führt. Um eine Fehlfunktion der Kupplung zu erkennen, werden die Raddrehzahlen der Antriebsräder auf Null geführt und ein elektrisches Signal zur Öffnung der Kupplung ausgegeben, wobei bei Drehen der Antriebseinheit eine Drehzahl (nw) einer, mit der Kupplung verbundenen Getriebeeingangswelle des Getriebes (5,8) überwacht wird, wobei in das Getriebe kein Gang eingelegt ist.
