Abstract: With the development of intelligent vehicle technology, the functional requirements for intelligent cockpit systems are increasing day by day. Tight coupling design under traditional architecture is difficult to meet the needs of efficient expansion and resource optimization. Therefore, it is necessary to explore new architecture design methods. In this paper, an intelligent cockpit design scheme based on service-oriented architecture (SOA) is proposed to realize a highly modular and flexible on-board system. The atomized service design is combined with SOA architecture, and the improvement effect on resource utilization of electronic control unit (ECU) is evaluated through simulation experiments and data analysis. The experimental results show that the SOA architecture significantly reduces the ECU resource occupancy of navigation and media playback modules, and the overall optimization rate reaches 48.28%. Therefore, the SOA architecture can effectively improve the resource utilization efficiency and system flexibility of the intelligent cockpit system, ensure the efficient operation of the intelligent cockpit under the complex functional requirements, and meet the trend of intelligent and interconnected development.
