Abstract
In a drive train that includes an internal combustion engine and two electric drive units, drive torque of the internal combustion engine is superimposed on drive torque of an electric drive unit by means of a planet set to which the drive torque of the internal combustion engine is fed via a sun gear. The torque of the electric drive unit is transferred for different shift positions of a clutch by driving different ring gears of the planet set. The electric drive unit can be coupled directly to the input shaft via a clutch or can be coupled to a sun gear of the pick off gear unit via a clutch.
