The worst-case analysis of CAN message response-time without errors on car information central control system

Event-Triggered Communication Systems (ET systems) are not composable, so the properties of the whole system do not follow the properties ofsuhsystems. In this paper, we deal with the communication of CICCS (Car Information Central Control System) under normal condition and some accidents, aiming at improvement of the whole dependability of CICCS. Adopting the worst-case analysis of CAN message response time without transmission errors, all the messages of ClCCS is studied. From the analysis, we find that, when two buses reach the high enough speeds, all of the messages meet their timing requirements.
