摘要
针对CAN-FD灵活速率的特点,根据总线各部分的功能要求进行模块划分,分别建立侦听、发送、信息处理模块模型。基于MATLAB软件,利用有限状态机对CAN-FD总线进行形式化的建模设计。状态机模型在仿真时能够动态展示总线系统的通信行为,适合搭建CAN-FD总线网络的优化仿真平台。在此仿真平台的基础上,以电动汽车通讯网络为例对CAN-FD网络进行仿真,并在性能指标方面与传统车辆CAN网络进行对比分析。
According to the characteristics of CAN-FD flexible speed,the functional requirements of each part of the bus module division,CAN-FD bus model is designed using finite state machine based on MATLAB software.The state machine model can dynamically show the communication behavior of the bus system during the simulation,and it is suitable for building an optimized simulation platform of CAN-FD bus network.Based on this simulation platform,CAN-FD network is simulated with electric vehicle as an example,and the performance index is compared with CAN network.
