Abstract: A method for error management in a system having a plurality of components, error conditions of the components being able to be indicated by status values, includes a first status value being determined as a function of an error condition of a first component, and of a second status value being determined as a function of an error condition of a second component and as a function of the first status value.

Abstract: In a method for determining a target state in a system having multiple components, system states of different priorities being selectable in the system as a function of an availability of the components, the following steps are provided: ascertaining whether a highest-priority system state is selectable; determining the highest-priority system state as the target state if the highest-priority system state is selectable; and ascertaining whether a next-higher-priority system state is selectable if the highest-priority system state is not selectable, and determining the next-higher-priority system state as the target state if said state is selectable.
