DISTRIBUTED REAL TIME COMPUTER SYSTEM AND METHOD FOR IMPOSING THE FAIL SILENT BEHAVIOUR OF A DISTRIBUTED REAL TIME COMPUTER SYSTEM

摘要

The invention relates to a method for forcing fail-silent behavior of a periodically functioning, distributed real-time computer system, which real-time computer system comprises at least two redundant NSCFCUs. At the beginning of a frame, the at least two redundant NSCFCUs (110, 111) are supplied with the same input data, wherein each of the redundant NSCFCUs calculates a result, preferably by means of a deterministic algorithm, particularly from the input data, and wherein this result is packed into a CSDP with an end-to-end signature, and wherein the CSDPs of the NSCFCUs (110, 111) are transmitted to an SCFCU (130), and wherein the SCFCU (130) checks whether the bit patterns of the received CSDPs are identical, and, if disparity of the bit patterns is found, prevents further transmission of the CSDPs, particularly those CSDPs in which disparity was found. Furthermore, the invention relates to a periodically functioning, distributed real-time computer system.
