A clutch device has at least a multiplicity of clutch discs which are in frictional contact with one another, and a control unit which controls the clutch device. The clutch device is calibrated repeatedly during an operating time of the clutch device. A first calibration is performed at a first point in time. A second calibration is performed at a second point following the first calibration. The first point in time and the second point in time are within a first operating time of the clutch device and occur within a first time interval. At least a third calibration is performed in a subsequent second operating time at a third point in time. At least the second calibration is performed within a second interval of the third point in time. The first and second intervals are determined by the control unit based on a mileage of a vehicle or an energy input into the clutch device. The first interval is shorter than the second interval.
