Abstract

The power train of a motor vehicle has an automated transmission and/or an automated clutch, at least one control unit and at least one actor receiving signals from the control unit and serving to control the operation of the automated constituent or constituents of the power train. A preferably reestablisbable connection can be interrupted in the event of a malfunctioning of the power train, such as exhaustion of the supply of electrical energy, defectiveness of the actor and/or defectiveness of the automated constituent or constituents and/or defectiveness of the motion transmitting connection or connections between the actor and the automated constituent or constituents. This renders it possible to set the transmission in neutral or into another gear and/or to select the condition of the clutch in such a way that the vehicle can advance to a selected destination under it own power or that it can be towed to such destination.
