1. Method for adapting a relationship stored in an electronic control unit, between a moment transmittable by a clutch, and a control variable for controlling an actuation unit of the clutch, which clutch is arranged in an automated motor vehicle drive train with a torque detection device arranged between the clutch and a transmission with a steplessly changeable transmission ratio for producing an output parameter dependent upon a detected moment and the momentary transmission ration of the transmission, by which method the moment transmitted by the clutch is calculated from the momentary transmission ratio and the value of the output parameter, and in an operating condition of the clutch in which the transmittable and transmitted moment of the clutch are equalized, the transmitted moment is coordinated with the control variable as an updated transmittable moment.
