Abstract: The invention relates to a drive system, a control device, and a method for controlling a mechanical shifting operation in the drive system. The drive system has at least one first multi-gear transmission, having a first input shaft and a first mechanical shifting means. Torques coming from the first input shaft are transmitted to a drive system output shaft. The torques are produced by an internal combustion engine and/or at least one first electric motor. For the purpose of disengaging a gear of the multi-gear transmission, the first electric motor is connected to the internal combustion engine and operated in a generator operating mode at least at times during the shifting operation, whereby the internal combustion engine is loaded and the first mechanical shifting means is unloaded. The mechanical shifting means is thus free of load or torsion and can be easily disconnected/opened.
