The invention relates to a method for teaching-in a gear shift drum (100) in a hybrid drive train (10), wherein the hybrid drive train (10) comprises a first drive machine in the form of an internal combustion engine (12) and a second drive machine in the form of an electric machine (16), as well as a transmission assembly (18) which can be connected to the first drive machine (12) via a switch element (K0), and is/can be connected to the second drive machine (16), wherein the transmission assembly (18) comprises an input shaft (26) and an output shaft (34) and a plurality of gear stages (40, 46, 56) arranged in between, which are designed such that they can be switched via associated switch elements (K1, K2, K3), wherein the switch elements (K0, K1, K2, K4) are switched via a gear shift drum (100) that can be rotated about 360 degrees, comprising the steps of: rotating the gear shift drum (100) into a first switch state which corresponds to a neutral position of the transmission assembly (18); generating a low rotational speed by means of the electric machine (16), producing a differential speed at at least two switch elements (K0, K2) of the transmission assembly (18); rotating the gear shift drum (100) in a first rotational direction into a second switch state, wherein a first switch element (K0) is switched with the differential speed, such that the electric machine (16) is abruptly decelerated to zero, wherein a rotational speed signal of the electric machine (16) is generated and this rotational speed signal is assigned to a first reference position/reference angle as a virtual end stop; rotating back the gear shift drum (100) into the first switch position and rotating the gear shift drum (10) in the second rotational direction into another switch state, wherein a second switch element (K2) is switched with the differential speed, such that the electric machine (16) is abruptly decelerated to zero, wherein a rotational speed signal of the electric machine (16) is generated and this rotational speed signal is assigned to a second reference position/rotational angle as a virtual end stop.
