Hierarchical operation control method and system of an ethernet node and vehicle
By using a hierarchical operation control method, the operating status level of the Ethernet node is determined based on the hierarchical decision reference signal, and the functions of the vehicle OSI seven-layer network model are enabled or disabled as needed. This solves the problem of high power consumption of traditional vehicle Ethernet nodes and realizes precise control and low-power operation of the internal modules of the node.

AI Technical Summary
Traditional automotive Ethernet nodes, despite their high integration, suffer from high power consumption, large wake-up range, and poor mapping to demand scenarios, leading to battery depletion.
A hierarchical operation control method is adopted to determine the operating status level of the node based on the hierarchical decision reference signal, and to enable or disable the corresponding layer functions of the on-board OSI seven-layer network model as needed, so as to realize the precise start and stop control of the internal modules of the node layer by layer.
It reduces the power consumption of Ethernet nodes when there is no business demand, improves network response speed, adapts to the network load and functional requirements of different driving scenarios, and reduces data processing overhead and resource consumption.
