A method is provided for operating a drive unit for a hybrid vehicle. Through a planetary transmission, an electric motor is coupled to an input shaft of a first sub-transmission and an input shaft of a second sub-transmission shifted in parallel to the first sub-transmission. Through a frictional-locking separating clutch, an internal combustion engine is able to be coupled to the input shaft of the first sub-transmission and, if the separating clutch is locked, is coupled to the same element of the planetary transmission together with the input shaft of the first sub-transmission. For coupling the internal combustion engine at the output coming out of all-electric driving, the torque provided by the internal combustion engine is transferred through the slip-controlled separating clutch in order to unload the previously locked shift element and disengage it in the unloaded state.
