Abstract
A method for operating a multi-clutch transmission for a motor vehicle, having at least the following steps: a) closing a first clutch of the multi-clutch transmission, in order to transfer an input torque (M_k) between a drive machine of the motor vehicle and at least one first sub-transmission of the multi-clutch transmission; b) applying a drag torque (M_k) to a second sub-transmission of the multi-clutch transmission, which is coupled to the first sub-transmission, via a second clutch of the multi-clutch transmission; c) detecting a clutch slip of the second clutch, which is dependent on the drag torque (M_k); and d) determining a current gear selection of the multi-clutch transmission by evaluating the clutch slip. The disclosure further relates to a multi-clutch transmission and to a motor vehicle having a multi-clutch transmission.
