Abstract
Disclosed is parallel hybrid drive for a motor vehicle, a motor vehicle, a method for operating a parallel hybrid drive in an all-electric mode, a method for operating a parallel hybrid drive in a direct drive mode, and a method for operating a parallel hybrid drive in a CVT mode. The drive for a motor vehicle includes an electric machine operable as a motor and generator, an internal combustion engine, a drive axle, and an epicyclic gear. The epicyclic gear includes: a first shaft connected to the electric machine; a second shaft connected to the internal combustion engine; and a third shaft connected to the drive axle. A clutch element is configured to firmly connect at least two shafts of the epicyclic gear to each other. A first brake element is configured to prevent rotation of the internal combustion engine in one direction of rotation.
