Claim:
1. A drive unit for a hybrid vehicle, comprising: a drive assembly with an internal combustion engine, an electric motor, and a transmission with at least a first sub-transmission parallel to a second sub-transmission between the drive assembly and an output; the electric motor coupled to an input shaft of the first sub-transmission and an input shaft of the second sub-transmission through a planetary transmission; the internal combustion engine able to couple to the input shaft of the first sub-transmission through a clutch and, when the clutch is locked, is coupled to a same element of the planetary transmission as the input shaft of the first sub-transmission; a bypass shift element configured in such a manner that: (a) when the bypass shift element is locked, 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 exists, and (b) with the bypass shift element open, the torque-proof connection between the electric motor and the two input shafts of the two sub-transmission does not exist; wherein the clutch is a frictional-locking or positive-locking separating clutch, and the bypass shift element is a frictional-locking bypass shift element; and the frictional-locking bypass shift element is interactively configured with the transmission as a power-shifting element for execution of a power shift in an all-electric driving mode, wherein:
