Abstract

An electric drive system for a motor vehicle includes a first electric machine with a first rotor, a second electric machine with a second rotor, and a planetary transmission which has a first planetary gear set, a second planetary gear set, a first input shaft, a second input shaft, a first output shaft, and a output input shaft. The first input shaft introduces first torques originating from the first electric machine into the planetary transmission. The second input shaft introduces second torques originating from the second electric machine into the planetary transmission. The first output shaft discharges third torques from the planetary transmission. The second output shaft discharges fourth torques from the planetary transmission.
