Method for detecting the status of the clutch in the drive train of a motor vehicle
Abstract:
In a method for detecting the status of the clutch in the drive train of a motor vehicle, the engine speed and the speed are ascertained and a transmission ratio is formed as the quotient of the engine speed and speed. Furthermore, a reference value is determined, which is set equal to the transmission ratio from a first time step. In a subsequent time step, the difference between the instantaneous transmission ratio and the reference value is formed, a disengaged clutch status being detected if the difference exceeds a threshold value.
