Abstract

The invention relates to a drive train for a motor vehicle, having an internal combustion engine (1), having an electric machine (2), which upon starting of the engine (1) generates a torque, and having a clutch (3), which is disposed between the engine (1) and a gear train (4) by way of which a torque generated by the engine (1) can be transmitted to at least one vehicle drive wheel. A mechanism (5, 6) is provided, which upon starting of the engine can actuate the clutch (3) in such a way that a first part of the torque generated upon starting of the engine by the electric machine (2) is transmitted to the at least one vehicle drive wheel, and a second part of the torque generated by the electric machine and sufficient for starting the engine is transmitted to the engine.
