摘　　要：面向汽车电子的分布式实时系统通信中间件,须处理大量周期通信或非周期通信事件,并对时间有着严格的限制,不能有效进行通信时刻控制。为此,参考AUTOSAR规范,从实时性保证与柔性配置管理角度出发,提出一种分布式实时应用的通信中间件。该通信中间件具有可重用性、可裁减性和可配置性,可应用于多种操作系统及硬件平台。通过通信中间件的运行示例分析,验证了该通信中间件的可行性。Facing to Distributed Real-time Systems（DRS） of automotive electronic, communication middleware must handle many aperiodic and periodic communication events under strict time requirements, they can not control communication time. This paper proposes a communication middleware of distributed real-time application referencing AUTOSAR standard by requirements of real-time and flexible configuration mechanism. It has reusability, tailorability and configurability, can hide the difference of communication protocols and be used to different operation system and platforms. Application case analysis of a communication middleware show its feasibility.
