Abstract

A transmission (G) for a motor vehicle includes an electric motor (EM), an input shaft (GW1), an output shaft (GW2), two planetary gear sets (P1, P2), and at least five shift elements (K1, B1, K2, K3, K4), wherein different gear ratios between the input shaft (GW1) and the output shaft (GW2) are selectable by actuating the at least five shift elements (K1, B1, K2, K3, K4) and, in addition, in interaction with the electric motor (EM), different operating modes are implementable. A drive train for a motor vehicle including such a transmission (G) and to a method for operating same are also provided.
