A Design Scheme of Vehicle Network Non-hibernation Monitoring System
【Abstract】This paper introduces the architecture scheme and design principle of vehicle network no-sleep monitoring system,the interactive control logic between the gateway of no-sleep monitoring main control module,T-BOX of vehicle intelligent communication module,and TSP background. A monitoring method of vehicle network hibernation wake up anomaly is proposed,which can monitor the state of vehicle network in real time,and quickly locate the abnormal ECU,which is convenient for locating and troubleshooting problems.
