To improve the network communication reliability, the influence of ECU power supply and location on network architecture is analyzed in this chapter and some scenarios are presented. For ECU power supply, the network with KL15-ECUs and the network with KL30-ECUs, and the network mixed KL15-ECUs and KL30-ECUs are evaluated separately according to network management and physical layer characteristic. The relevant requirements for the network architecture are obtained for different scenarios. For ECU location, some ECUs will result in risks for the network communication during collisions. In this study, adaptive cruise control (ACC), and active frontlight system (AFS) are analyzed. The corresponding optimization solution is given by designing separated network architecture. The results are applied to a C class passenger car successfully.
