Abstract

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Ermitteln des Übertragungsverhaltens einer automatisierten Kupplung (2) im Stillstand eines Fahrzeugs, wobei die Kupplung mittels eines Kupplungs-Steuergeräts (1) automatisch verstellt und das übertragene Kupplungsmoment ermittelt wird. Um das Übertragungsverhalten der Kupplung (2) in einem möglichst großen Momentenbereich ermitteln zu können, wird vorgeschlagen, die Fahrzeugbremse (6) während der automatischen Verstellung der Kupplung (2) von einem Brems-Steuergerät (5) automatisch zu betätigen, um das Fahrzeug am Anfahren zu hindern.
