中文摘要:针对汽车动力控制系统中实时控制信息通信的高性能需求,提出了基于TTCAN协议的均匀装载(AL)调度算法来解决时间触发调度问题,分析了AL方法的调度策略,应用基于TTCAN协议的AL 调度算法和基于CAN协议的RM算法对汽车控制系统信息分别进行了网络调度设计。通过对实时性、周期抖动和总线使用率等网络性能指标的分析和对比,证实了新TTCAN方案比传统CAN方案具有更好的性能。

Abstract:Aimed at meeting high performances of automotive real-time control system and based on time-triggered CAN (TTCAN), a new average-loading (AL) scheduling algorithm was proposed and the scheduling strategy was explained concretely. The AL scheduling algorithm based on TTCAN and rate monotonic (RM) based on CAN were respectively used to schedule the network of typical automotive control system. According to the special requirements of automotive network, three criterions of network capability including real-time capability, period jitter and bandwidth utilization factor were explained. Finally, the networks based on the two algorithms were respectively analyzed and compared with the criterions. The result verified the feasibility and superiority of the AL algorithm based on TTCAN.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
