Abstract: In view of the automatic driving function of the freeway, the human-machine interaction plan designed in this paper takes full account of how to make the driver establish trust in the automatic driving system, and display the surrounding environment and function state of the autopilot to the driver in a reasonable way through instruments, MP5, seat belt vibration and so on. When the system is unable to complete the driving task and requires the driver to take over, the human-machine interaction system can give users multi-dimensional reminder through the way of vision, hearing and touch, so as to ensure the smooth handover between the driver and the automatic driving system.

摘要： 针对高速公路自动驾驶功能，文章所设计的人机交互方案，充分考虑了如何让驾驶员建立对自动驾驶系统的信任，将自动驾驶的周围环境和功能状态以合理的方式通过仪表、MP5、安全带震动等方式展现给驾驶员。在系统无法完成驾驶任务，需要驾驶员接管时，人机交互系统能够通过视觉、听觉、触觉的方式，给用户多维度的提醒， 确保车辆驾驶权在驾驶员和自动驾驶系统之间的顺利交接。
