Abstract
A motor vehicle drive includes an electric motor and at least one clutch in the drive line between the electric machine and the driven wheels of a motor vehicle. If the special case occurs in which high torques have to be supplied by the electric motor when the vehicle speed is very low or when the vehicle is stationary, the clutch is operated in a torque-transmitting slipping manner, ensuring that neither the electric machine nor the clutch are thermally overloaded.
