车载FlexRay网络调度算法综述

FlexRay是为车载网络系统中高速率通信需求而开发的网络通信标准,将事件触发和时间触发2种方式相结合,以满足汽车安全性和可靠性的需求。由于其良好的发展前景,得到了学界和企业界的广泛关注,在提高网络利用率和可靠性方面开展了很多研究。而消息调度算法在提高网络性能方面起着至关重要的作用,为此,从静态段消息调度、动态段消息调度和CAN/FlexRay混合网关消息调度等3个方面对近年来消息调度相关研究进行了详细的总结和分析,并指出了当前研究的不足和未来可能的研究方向。

Review on vehicle FlexRay network scheduling algorithm

FlexRay is a network communication standard developed for high-speed communication demand in vehicle network system, which combines two modes time-triggered and event-triggered, so it can meet demands of safety and reliability. Due to its good development prospects,it is paid wide attention, a lot of research are carried out in order to improve network utilization and reliability. The message scheduling algorithm has a significant impact on improving network performance. For this purpose, detailed summary and analysis is carried out on relevant research of information scheduling in resent years ,from three aspects of static and dynamic segment, and CAN/FlexRay hybrid gateway information scheduling, and shortages of current researches and future research direction are pointed out.
