12. A drive system for a hybrid motor vehicle, the drive system comprising:
a motor shaft configured to be rotationally coupled to an output shaft of an internal combustion engine;
a first electric motor which has a first rotor shaft;
a second electric motor which has a second rotor shaft arranged in a radially offset manner to the first rotor shaft;
a drive part rotationally connected to the second rotor shaft and which is rotationally connectable to at least one wheel of the motor vehicle;
a transmission unit is configured to be shifted operatively installed between the motor shaft, the two rotor shafts, and the drive part;
a shift device which controls a shift position of the transmission unit being operatively installed between the motor shaft, a first gear, which is permanently rotationally coupled to the first rotor shaft, and a second gear, which is permanently rotationally coupled to the second rotor shaft via an additional planetary transmission stage, such that the shift device in a first shift position rotationally connects the motor shaft to the first rotor shaft while the second rotor shaft is rotationally decoupled from the motor shaft, in a second shift position rotationally connects the motor shaft both to the first rotor shaft as well as to the second rotor shaft, and in a third shift position rotationally connects the two rotor shafts together while the motor shaft is rotationally decoupled from the two rotor shafts.
