A real-time monitoring system of vehicle steering simulator design based on Matlab CAN communication

汽车转向模拟器是实现人-车硬件/软件在环仿真试验的关键装置。文章基于Matlab图形化用户界面(GUI)设计了转向模拟器监控系统,利用Matlab的车载网络工具箱,通过CAN通信协议实现转向模拟器与PC机之间的实时通讯。系统界面简单,操纵方便,通过参数配置实现转向模拟器不同的工作模式。实验结果表明,系统运行快速稳定,以100Hz的频率收发报文和10Hz的频率更新界面显示,能够精准的控制转向模拟器在不同的工作模式下运行。

Vehicle steering simulator is the key device to realize driver–vehicle hardware/software in the loop simulation experiments. This paper, the monitoring system of the steering simulator was designed based on Matlab GUI. Vehicle Network Toolbox in Matlab and CAN communication protocol were used to realize the real-time communication between steering simulator and PC. The interface of the system is simple and easy to operation. Variety work models were achieved by setting different parameters. The test results show that, the system runs stability and fast, and can accurately control steering simulator working in different models with transmitting message at 100 Hz and updating interface display at 10 Hz.
