【Abstract】Withthe development of automotive intelligence，networking，sharing and electrification，the iteration of automotivesoftware isfrequentandthe in-vehicle communication datais surging.Traditional busescannotmeet the demands and Ethernetcommunication needs tobe introduced.Remote online upgrade （Over the Air，OTA） requires informingusersof theupgradecontentand involvesalarge amount ofdata transmission.Therefore，an I-basedserviceoriented scalable middleware （SOME/IP）based on Ethernet is adopted.Combined with the OTAupgrade function，this article ntroduces the development processand methods based on the SOME/IP protocol， providing guidance forthe development of in-vehicle Ethernet networks.
