Zusammenfassung:	The invention relates to a multi-speed power shifted hybrid transmission (10), comprising a housing (H), an input shaft (11) connected to a prime mover (12), a first driveshaft (13), a second driveshaft (14) being arranged concentric to the first driveshaft (13), each of the two driveshafts (13, 14) having a plurality of driving gearwheels (G12a, G3a, G4a, G5a; G6a) on them, at least one driven (15, 18) shaft with at least one driven gearwheel (G12b, G3b, G4b, G5b; G6b; GRb) on it meshing with the driving gearwheels (G12a, G3a, G4a, G5a; G6a) on said driveshafts (13, 14) thus forming gearings (G1/2, G3, G4, G5; G6; GR); a plurality of controllable clutches (C0, C1, C2, C3, C4), selectively connecting said gearwheels (G12a, G3a, G4a, G5a; G6a; G12b, G3b, G4b, G5b; G6b; GRb) to the corresponding shafts (13, 14), in a way engaging the gearings (G1/2, G3, G4, G5; G6; GR) with different gear ratios, an electric machine (17), a planetary gearset (20) with at least three links, a first (21) of said links being connected to the input shaft (11), a second link (22) being connected to the second driveshaft (14), and a third link (23) being kinematically connected to the rotor (17a) of said electric machine (17) in a way that a speed ratio between the second link (22) and the third link (23) is negative for stopped first link (21), with a controllable lock-up clutch (CL), blocking relative rotation between the first driveshaft (13) and the second driveshaft (14), with a controllable friction clutch (C0), connecting the input shaft (11) kinematically to the first driveshaft (13). The transmission (10) further comprises a controllable brake device (B0), blocking the rotation of the input shaft (11) against the housing (H), wherein at least one of the gearings (G1/2, G3, G4, G5; G6) can be engaged with reversed gear ratio from the second driveshaft (14) to any of the driven shafts (15, 18).
