Abstract:
A drive train for a motor vehicle, having an internal combustion engine (1) and an electric machine (2), wherein said electric machine generates a torque upon starting of the engine (1), and having a clutch (3), wherein said clutch 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, wherein means (5, 6) are provided, wherein said means, 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 (2) and sufficient for starting the engine (1) is transmitted to the engine, wherein sensors are provided, wherein said sensors detect an exceptional state in which the motor vehicle, because of external forces, would undesirably put itself into motion, because the torque transmitted upon starting of the electric machine to the at least one vehicle drive wheel is too low to prevent the unwanted motion of the motor vehicle.
