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
