Abstract

A method for actuating a component of a drive train of a motor vehicle. The component is mechanically prestressed into a safe state. The method has the steps: sensing a fault state; sensing whether the fault state is a first or second type of fault state; immediate interruption of the actuation of the component so that the component is passively transferred into the safe state by the mechanical prestress if the fault state, is of the first type of fault state, or actuation of the component in such a way that the component is actively transferred into the safe state if the fault state is of the second type of fault state.
