Abstract
A method and a device for controlling a clutch, for example an automatic friction clutch forming part of a drive train of a motor vehicle, for a torque transfer between an engine and a transmission, with the clutch having significant clutch way points assigned to it. For achieving the operational readiness of the clutch over the shortest possible time period, whereby an accurate clutch adjustment is still guaranteed, a clutch way point coordinate system is monitored by checking the point of engagement of the clutch, established through a learning process and having at least a relevant clutch way point for the starting procedure. In case of any recognized change(s), the clutch way point is suitably corrected or otherwise used as is.
