Abstract:
A multi-speed planetary coupling transmission (3) which includes a plurality of planetary gear sets (4, 5, 6) and a plurality of shifting elements (A, B, D, E). Depending on actuation of the shifting elements (A, B, D, E), various gear ratios can be achieved by the transmission. At least one provided electric machine (EM1) is functionally connected with one of the planetary gear sets (6). From the electric machine (EM1), a torque can be introduced, via a shaft (6B) of the planetary gear set (6) associated with the electric machine (EM1), in order to support torque acting on the associated planetary gear set (6) and achieve a gear ratio in the transmission (3) via the electric machine (EM1).
