Abstract

A transmission (G) for a motor vehicle includes an electric machine (EM1), a first input shaft (GW1), a second input shaft (GW2), an output shaft (GWA), two planetary gear sets (P1, P2, P3), and at least five shift elements (A, B, C, D, E). Different gears are implementable by selectively actuating the at least five shift elements (A, B, C, D, E) and, in addition, in interaction with the electric machine (EM1), different operating modes are implementable. A drive train for a motor vehicle with such transmission (G) and to a method for operating such transmission (G) are also provided.
