AI Technical Summary

Technical Problem

The complex configuration of in-vehicle Ethernet networks makes network connectivity checks difficult, requiring a significant amount of effort to perform network connection tests to ensure correct configuration.

Method used

By transmitting messages carrying message identification information between various control nodes in the Ethernet network, the message information is determined, and node diagnostic data is generated based on this information. Finally, the master control node determines the network connection diagnostic results, ensuring that the connectivity of all control nodes is diagnosed.

Benefits of technology

It improves the efficiency and completeness of network connectivity diagnostics, reduces data storage redundancy, and ensures rapid triggering and accuracy of network connectivity.

Abstract

The present application relates to a kind of network connection diagnostic method, control node and storage medium, control node is any node in Ethernet, data transmission between each control node in Ethernet is based on preset Ethernet protocol, method includes: in the case where receiving the first message carrying the first message flag information sent by other control node in Ethernet, determine the message information of first message;Other control node is the control node with control node there is unicast or multicast relationship;Determine the node diagnostic data corresponding to control node based on message information, and send node diagnostic data to the main control node in Ethernet, for the main control node based on node diagnostic data determines the network connection diagnostic result of Ethernet.The present application diagnoses the network connection between each control node in each control node of Ethernet by message receiving condition, to obtain the network connection diagnostic result of Ethernet, improves the efficiency of network connection diagnosis.
