Abstract
A transmission unit for a motor vehicle has a drive shaft for a connection to an internal combustion engine of the motor vehicle, an output shaft for the driving of the motor vehicle, a change speed gearbox, an additional drive motor and a planetary transmission, with the additional drive motor being coupled to a first part of the planetary transmission and the output shaft being coupled to a second part of the planetary transmission. The change speed gearbox has at least one selectable gear stage via which the drive shaft of the transmission unit can be operationally coupled directly to the output shaft while bypassing the planetary transmission. The change speed gearbox furthermore has at least one second selectable gear stage via which the drive shaft can be operationally coupled indirectly to the output shaft via a third part of the planetary transmission.
