Abstract

A hybrid drive system includes an internal combustion engine having a first output shaft, an electric machine having a rotor with a rotor shaft as second output shaft, and a transmission having a four-shaft, first planetary set, a second planetary set, a first shifting element, a second shifting element, a third shifting element, and a third output shaft. The four-shaft, first planetary set has a first shaft, a second shaft, a third shaft, and a fourth shaft, the second planetary set has a first element, a second element, and a third element. The first shaft, the second shaft, the third shaft, and the fourth shaft are rotatable relative to one another and connectable to one another in a rotationally fixed manner by a blocking shifting element. The first output shaft is coupled or is couplable to the first shaft in a rotationally fixed manner.
