Verfahren zur Steuerung eines Fahrzeugtriebstranges, das Folgendes umfasst:(a) Trennen einer Kupplung, die eine Komponente mit einem Fahrzeugrad verbindet;(b) Drehen der Komponente durch einen Sumpf durch pulsieren lassen der Kupplung, wenn die Drehzahl der Komponente niedriger als eine Referenzdrehzahl ist;(c) zyklisches Pulsierenlassen der Kupplung, während die Drehzahl der Komponente die Referenzdrehzahl überschreitet und ein Zählwert eines Zeitzählers, der eingeschaltet wird, wenn die Kupplung getrennt wird, einen Referenzzählwert überschreitet. A method for controlling a vehicle drivetrain includes de-energizing a clutch that connects a differential output to a wheel, rotating said component through a sump by pulsing the clutch when a speed of a differential component is less than a reference speed, and cyclically pulsing the clutch while a speed of said component exceeds the reference speed and a count of a timer, started when the clutch is de-energized, exceeds a reference count.
