Abstract

A hybrid drive of a motor vehicle has an internal combustion engine, an electric machine, an automated manual transmission with an input shaft and an output shaft, and a phase shifter gearbox in a planetary design with two input elements and one output element. A first input element of the gearbox is connected to a hollow shaft arranged in a coaxial manner around the output shaft, which is connectable to an idler gear of an axially adjacent spur gear stage of the manual transmission, and, for bypassing the gearbox, is connectable to the second input element or the output element of the gearbox. The second input element of the gearbox is permanently in drive connection with a rotor of the electric machine, and the output element of the gearbox is connected in a torque-proof manner to the output shaft.
