Abstract: In order to promote the rapid application of on-board ethernet and service oriented architecture (SOA) in the vehicle, this paper introduces the development method and process of SOA functional architecture based on model combined with examples, and also, the design of serviceoriented ethernet communication based on scalable service oriented middleware over IP (SOEMIP) protocol is bound, which has certain guiding significance for the development of automotive SOA functional architecture and ethernet network architecture.
