Development of Vehicle Domain Controller Based on Ethernet

The 'new four modernizations' of automobiles with the trend of electrification, intelligence, network connection and sharing has brought new challenges to the electrical/electronic architecture of vehicles. The topology of the vehicle has changed from distributed ECU development to the centralized oriented domain controllers and central computers; the function of the whole vehicle has been changed from decentralized software development to the development of a unified software architecture for aggregation. This paper studies the Ethernet-based on-board domain controller and expounds the research method for the unified architecture platform. Based on the SOA model, it discusses the definition of services based on SOME/IP, the software architecture, the hardware topology, and communication layer parameters; and builds a domain controller hardware platform, and simulates the development content in the later stage to form a complete Development process of Ethernet-based on-board domain controller.
