Abstract: A hybrid drive of a motor vehicle having an automated manual transmission with two input shafts and a common output shaft. The first input shaft can be connected to the drive shaft of an internal combustion engine by a clutch and can be brought into a drive connection to the output shaft by a first group of shiftable gearwheel sets. The second input shaft has a drive connection to the rotor of an electric machine, which can operate as a motor and a generator, and can be brought into a drive connection with the output shaft by a second group of selectively shiftable gearwheel sets. The input shafts can be coupled by coupling-shift element. The hybrid drive is provided with a second electric machine, which can operate as a motor and a generator and has a rotor that can be connected to the first input shaft.
