Abstract

Die Erfindung betrifft ein Verfahren zur Stabilisierung eines Reibwertgradienten einer Kupplung in einem Kraftfahrzeug, bei welchem ein Antriebsstrang mittels einer Kupplung mit einer Brennkraftmaschine verbindbar ist und ein Moment auf einen Abtrieb übertragen wird, wobei der Antriebsstrang einen eingelegten Gang aufweist. Bei einem Verfahren, bei welchem ein nahezu konstanter positiver Reibwertgradient gewährleistet wird, wird bei einer Fahrt des Kraftfahrzeuges in einem Niedriglastbereich die Kupplung kurzzeitig in einen Schlupf gebracht.
