A drive unit for a hybrid vehicle includes a drive assembly with an internal combustion engine and an electric motor, and a transmission featuring several sub-transmissions shifting between the drive assembly and an output. Through a planetary transmission, the electric motor is coupled to an input shaft of a first sub-transmission and an input shaft of a second sub-transmission. Through a separating clutch, the internal combustion engine is 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 as the input shaft of the first sub-transmission. A bypass shift element works with the planetary transmission such that, with a locked bypass shift element, a torque-proof connection between the electric motor, the input shaft of the first sub-transmission and the input shaft of the second sub-transmission exist, while, with an open bypass shift element, this torque-proof connection between the electric motor and the two input shafts of the two sub-transmissions does not exist. The separating clutch is formed as a frictional-locking or positive-locking separating clutch, and the bypass shift element is formed as a frictional-locking bypass shift element.
