Abstract

A planetary multi-stage transmission for a vehicle is provided. A drive (An) is connectable by a zeroth shift element (K0) to a first shaft (1). A first element of a first planetary gear set (RS1) is connected to a housing (9). A first shaft (1) is permanently connected to a second element of the first planetary gear set (RS1). A rotor (10) of an electric motor (EM) is connected to a third element of the first planetary gear set (RS1), and the third element of the first planetary gear set (RS1) is connectable by one or more of a plurality of additional shift elements to at least one element of one or more of a second and third planetary gear sets (RS2, RS3).
