A method for operating a drive train having a starting component between an electric machine and an output shaft of a transmission, and a separating clutch between an internal combustion engine and the electric machine, with a rotor of the electric machine being coupled to the input shaft of the transmission, where the method initially drives a motor vehicle solely by the electric machine while the starting component is engaged or slipping and the separating clutch is disengaged. The method then engages the separating clutch to crank the internal combustion engine. The method disengages the separating clutch after cranking, with an output-side rotational speed of the separating clutch being lower than an idling speed of the internal combustion engine. Subsequently, the method engages the separating clutch to drive the motor vehicle with the internal combustion engine when a target drive torque reaches or exceeds a limit.
