The invention relates to a hybrid drive train for a hybrid vehicle, comprising an electric machine (5) and an internal combustion engine (1), wherein a force output shaft (10) of said engine alternatingly acts either on a first input shaft (7) or on a coaxial second input shaft (9) of a dual clutch transmission (3) via two separating clutches (K1, K2) of a dual clutch, wherein a respective first and second sub-transmission (I, II) can be activated using the input shafts (7, 9), and wherein fixed and idler gears are arranged in wheel planes (RE1 to RE8) on the two input shafts (7, 9) and a common axially parallel output shaft (13), said fixed and idler gears being combined into gear sets which form gear stages (1 to 7, R), in which the idler gears can be coupled to the shafts (7, 9, 13) bymeans of gear shifting elements (G1 to G4), wherein the electric machine (5) acts on one (7) of the input shafts (7, 9) optionally via an intermediate gear (11), and an electric-machine-side shiftingelement (S) is interposed between the electric machine (5) and the cooperating electric-machine-side input shaft (7), said shifting element, in a first shifting position (S1), coupling the electric machine (5) to the electric-machine-side input shaft (7), and, in a neutral position (N), decoupling the electric machine (5) from the dual clutch transmission (3) . According to the invention, the electric-machine-side shifting element (S) can be shifted into a second shifting position (S2), in which the electric machine (5) is coupled to the output shaft (13) and is decoupled from the electric-machine-side input shaft (7).
