The drive traincomprising a hybrid drive with an internal combustion engine and an electric motor, atransmission arranged between the hybrid drive and a drive output, and a clutch arrangedbetween the internal combustion engine and the electric motor. The internal combustionengine is started by engaging the clutch only when the electric motor is providing drivepower. In this situation when shifting gears in the transmission with interruption of thetraction force, immediately after the gear change and during a load build-up phase of theshift operation, the internal combustion engine is started by the electric motor withouttraction force interruption. The clutch is controlled to partially engage to start thecombustion engine and then it is completely disengaged before reaching a synchronousspeed between the combustion engine and the electric motor.
