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), at least two planetary gear sets (P1, P2), and at least four shift elements (A, B, C, D). Different gears are selectable by selectively actuating the at least four shift elements (A, B, C, D). In interaction with the electric machine (EM1), different operating modes are implementable. A drive train for a motor vehicle that includes such a transmission (G) and to a method for operating same are also provided.
