A method for operating a drive train of a transportation vehicle wherein the drive train is switched between a first operating state, in which a two-wheel drive of the drive train is activated, and a second operating state, in which a four-wheel drive of the drive train is activated. The drive train is switched by an electronic computing device from one of the operating states to the other operating state. During the driving of the transportation vehicle, a demand time is determined by the electronic computing device not later than which the switching from the one operating state to the other operating state must be completed, the demand time lying in the future with respect to the determination of the demand time. The switching from the one operating state to the other operating state is commenced at a starting time in advance of the demand time.
