【Abstract】With the characteristics of large bandwidth，high reliability，low delay and high-precision clock synchronization，vehicular Ethernet has been planned as the backbone network of the new generation of electronic and electrical architecture by major host plants. At present，using DOIP technology for vehicle controller data writing and fault diagnosis has been a practical case. This paper focuses on the connection mode，activation line requirements and connection process of DOIP technology，which can be used as a reference for subsequent technology implementation.
