摘要： 根据汽车动力传动系统与车身控制系统的不同要求,研究了汽车整车分层控制网络的构建及其信息调度策略.在分析汽车控制系统信息特点的基础上,构建了动力传动时间触发控制器局域网(TTCAN)和车身控制器局域网(CAN)子网互连的整车分层网络,针对动力传动TTCAN子网提出均匀装载(AL)调度策略;针对车身控制CAN子网采用比率单调(RM)调度策略,通过对具体汽车控制信息的通信调度及实时性实例分析,验证了该方案的可行性.

关键词: 整车分层控制网络, CAN协议, TTCAN协议, 调度策略, 实时性分析

Abstract: To meet different requirements of automotive power transmission system and bodywork control system, a hierarchical control network was constructed for entire cars and its scheduling strategy was studied. Analyzing the characteristics of information in automotive control system, a new network was designed interconnecting TTCAN (time triggered controller area network) for power transmission system with CAN (controller area network) for bodywork control system. The AL (average loading) algorithm is proposed to schedule TTCAN and RM (rate monotonic) algorithm introduced to schedule CAN. Finally the scheme proposed is applied to automotive control system, and the result of real-time analysis verifies the feasibility of the scheme.
