【Abstract】With the rapid development of inteligent connectedvehicle technology，in-vehicleethernet has been widelyusedininteligentconnectedvehiclesduetoitshightransmissionrate.Thisarticlestudiestheworkingprinciple andtopological structureof vehicle-mountedethernet，andconductsan in-depthanalysisof itsfault diagnosis methods toimprovemaintenanceeffciency.Firstly，theapplicationoftheOSIseven-layermodelinvehicleethernetis introduced.Then，thestartopologystructureof ethernetanditsdiferences fromthetraditionalCANbusarediscussed. Next，thecommonfaultsof vehicleethernetareanalyzedandthe corresponding diagnosticmethodsareproposed. Through theanalysis of actual cases，itis expectedtoprovide guidanceforthefault diagnosisofon-boardethermet in intelligent connected vehicles.
