汽车虚拟仪表盘的仿真设计

摘要

汽车仪表盘反映了汽车行驶过程的多种参数，设计虚拟仪表盘仿真系统在教学科研中具有重要意义。在分析汽车仪表盘功能的基础上，提出了汽车虚拟仪表盘总体设计方案。编写通信程序实现了上位 PC 机和下位单片机系统的数据采集发布功能。应用VB开发了数字化汽车虚拟仪表盘界面与性能仿真系统，可模拟发动机转速、车速、温度、时间及里程等信息实时显示在计算机界面上；操作控制按钮可实现汽车转向灯指示功能。经实际试验运行显示该仿真系统工作正常，实现了对汽车仪表盘的仿真效果。%The automotive dashboard reflects a variety of process parameters. Designing the virtual automotive dashboard system is important for teaching and research. The overall design program was proposed by analyzing the function of automotive dashboard. The virtual dashboard interface and the performance simulation test system were developed based on VB, which can collect&transmit signal between PC and microcontroller. The engine speed, travel speed, temperature and mileage information were displayed on the PC interface by the calculation model. Operating the buttons can simulate the steering instructions. The experiment shows that the system works properly and has simulation results for the visual automotive dashboard.
