摘要:
The invention relates to a method for detecting the status of a clutch in the drive train of a motor vehicle, wherein the engine speed nMot and the speed Vaxle,M are detected, and a transmission ratio iges is generated as the quotient of the engine speed nMot and the speed Vaxle,M. Furthermore, a reference value igesRef is determined and is equated with the transmission ratio iges from a first time step. Finally, in a subsequent time step, the difference between the current transmission ratio iges and the reference value igesRef is generated, wherein a disengaged status of the clutch is detected when the difference exceeds a limit value Δiges.
