In the early development of vehicle body controller functions among domestic automobile manufacturers, usually texts were used to describe the system design. The dependency between various functions was blurring, and hardly to reuse. With the increasing demand for the number of functional requirements, in order to improve the reuse rate of various functions, Service-Oriented Architecture (SOA) solution is proposed in the industry. This paper excavates the design methodology knowledge of SOA architecture, summarize the practical experience of the design and development of the ambient light subsystem in the body control domain of Voyah automobile SOA platform, expounds the method of using Enterprise Architect (EA) software to complete the design of the system in the body control domain, deliver the development requirements documents and the system functional specifications, so as to achieve the purpose of improving the design efficiency and improving the design quality.
