Abstract

A motor vehicle transmission, shiftable between different transmission ratios, with an input shaft, an output shaft, and in some cases a countershaft has a plurality of gears arranged to cooperate in gear pairs, a plurality of clutches, and an electro-mechanical energy converter. The electro-mechanical energy converter can be coupled to the transmission through at least one of the clutches in order to perform at least one of the functions of starting the combustion engine of the vehicle, temporarily replacing or assisting the combustion engine in propelling the vehicle, maintaining vehicle traction during gear shifts, generating electrical energy from kinetic energy, and storing said electrical energy in a storage device.
