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.

Claims

1-16. -16. (canceled)

17. 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, comprising:

determining a first status value as a function of an error condition of a first component; and

determining a second status value as a function of an error condition of a second component and as a function of the first status value.

18. The method according to claim 17, wherein the status values indicate whether a value able to be provided by a component is valid or invalid, and the second status value is determined such that the second status value indicates that a value able to be supplied by the second component is invalid if the first status value indicates that a value able to be supplied by the first component is invalid.

19. The method according to claim 17, wherein an additional status value is determined as a function of an error condition of an additional component and as a function of the first status value.

20. The method according to claim 17, wherein the system includes a virtual component, and an error condition of the virtual component is determined from status values of a predefined number of the components according to a linkage specification, and a virtual status value is determined as a function of the error condition of the virtual component and as a function of the first status value.

21. The method according to claim 17, wherein, starting from the first status value, each status value whose determination is a function of a preceding status value, is determined only once.

22. The method according to claim 17, wherein a status value as a function of which no further status value is determined, is evaluated in order to determine which status value, starting from the first status value, first indicated that a value able to be provided by a component is invalid, in order to determine a faulty component.

23. The method according to claim 22, wherein a part of the system that has the faulty component is at least one of (a) degraded and (b) deactivated.

24. The method according to claim 22, wherein information about the faulty component is stored.

25. The method according to claim 17, wherein the error conditions of the components are determined by implementing monitoring algorithms.

26. The method according to claim 20, wherein the linking specification for determining the error condition of the virtual component is an AND operation.

27. The method according to claim 18, wherein the status values also indicate at least one of (a) whether a value able to be provided by a component is briefly invalid and (b) whether a component is not initialized, the second status value being determined such that the second status value indicates that a value able to be provided by the second component is invalid if the first status value indicates at least one of (a) that the value able to be provided by the first component is briefly invalid and (b) that the first component is not initialized.

28. A device, comprising:

an arrangement adapted perform 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, the method including;

determining a first status value as a function of an error condition of a first component; and

determining a second status value as a function of an error condition of a second component and as a function of the first status value

29. The device according to claim 28, wherein the components include at least one of (a) sensors, (b) actuators, (c) data-transmission controllers, (d) control-device components, and (e) signals transmittable by at least one of (i) sensors, (ii) actuators, (iii) data-transmission controllers, and (iv) control-device components

30. The device according to claim 28, wherein the system is a mechatronically embedded system.
