ABSTRACT:
A method of mutual monitoring of components of a distributed computer system for a safety-relevant application in a motor vehicle in particular. The components are interconnected by at least one communication system. To make the mutual monitoring of components as simple and comprehensible as possible and to save on additional hardware components for monitoring, in a plurality of components of the computer system an internal monitoring function which detects faults in the monitored component and a mutual monitoring function which performs a mutual check on results determined by the components and makes a majority selection from the results are implemented, and both the result of the internal monitoring function and the results of the mutual monitoring functions are taken into account in a decision as to whether there is a fault in a component.
