Abstract: With the improvement of various functions and performance requirements of automobiles, the traditional automobile distributed electronic and electrical architecture has been unable to meet the market demand, and automobiles are changing from electronic control unit (ECU) distributed electrical architecture to domain centralized electrical architecture. This paper summarizes the current design scheme of vehicle body domain controller, and analyzes the advantages of adopting domain controller scheme in combination with the current market demand. And a body domain controller is designed. Based on the functional requirements of the real vehicle, the scheme of the body domain controller is designed. The feasibility of the scheme is verified through the functional test on the bench and the real vehicle, which lays the foundation for the mass production of the scheme.

Key words: Distributed; Centralized; Electrical architecture; Body domain controller

摘要： 随着汽车各项功能和性能要求的提升，汽车分布式电气架构已不能适应市场需求，汽 车正在从电子控制单元（ECU）分布式电气架构向域集中式电气架构转变。文章对当前的车 身域控制器设计方案进行研究总结，结合当前的市场需求，分析采用域控制器方案的诸多优 点。并设计了一种车身域控制器，基于实车功能需求进行了车身域控制器的方案设计，通过 台架以及搭载实车进行功能测试，验证了方案的可行性，为该方案的量产奠定基础。
