Abstract:
An automatic clutch in a drive train of a motor vehicle, said drive train having a motorized adjusting unit which actuates the clutch and is controlled by a system of sensors, which allows a moment respectively transmitted by the clutch to be determined, the system of sensors sensing whether the clutch is operating with slip, and assigning a value of the transmitted moment of the clutch when slip is occurring to a respective value of the travel of the adjusting unit as the moment which can be transmitted by the clutch and evaluating said moment value together with said travel value for adapting a characteristic curve or table of values reflecting the dependence between the clutch moment and the travel of the adjusting unit, wherein, for determining a remaining amount of travel, the adjusting unit is at least for a short time brought into its end position for the engaged clutch under normal driving conditions and a warning signal is generated if the maximum transmissible clutch moment which can be achieved when the travel is exhausted falls below a threshold value.
