In either a pull-mode operating state or a push-mode operating state, a clutch arrangement assigned to the first gearbox input shaft and a clutch arrangement assigned to the second gearbox input shaft are actuated in such a way and a torque-generating arrangement comprising a drive unit is controlled in such a way that, when a shift is to be made between a first gear assigned to a first gearbox input shaft and a second gear assigned to a second gearbox input shaft, at least one of the following criteria with respect to the shifting sequence comprising the shift in question is fulfilled:(1) during the shifting sequence, the torque present at the gearbox output shaft is at least approximately constant or changes monotonically;(2) during the shifting sequence, the vehicle accelerates in an essentially monotonically increasing or in an essentially monotonically decreasing manner.
