Abstract:
1. A process for determining and monitoring a contact point of an automated clutch in a motor vehicle, wherein the motor vehicle features a control device, the process comprising the steps of: determining, by the control device, the contact point by means of an adaptation strategy that is executed as a non-safety function, the control point describing a position of the clutch from where the clutch begins to transmit a definite torque; and executing a monitoring process of the determined contact point using a monitoring module as a safety function, wherein the safety function of the determined contact point is at ready disposal, and the safety function of the monitoring module determines at least one band defining range of values for the contact point, the at least one band depending upon one of initially determined contact points, a default time scale, and a default tolerance and detects a non-plausible state of the clutch when the determined contact point lies outside of the at least one band.
