驾驶员疲劳状态监测系统综述

A Summary of Driver Fatigue State Monitor System

为提高车辆安全、减少因驾驶疲劳导致的交通事故,自20世纪80年代起,汽车厂商、零部件商以及科研机构开始从事驾驶疲劳方面的研究。本文总结了各种驾驶员疲劳状态监测系统的研究与应用情况以及整车厂在售车型配备的驾驶员疲劳状态监测系统及其工作原理,例如梅赛德斯-奔驰Attention Assist系统基于操纵行为监测驾驶员疲劳状态,丰田Driver Monitor系统基于驾驶员面部状态和眼睛开闭频率监测驾驶员状态,福特Driver Alert System采用多维信息融合的方法监测驾驶员状态,等等。本文分析了目前各种驾驶员疲劳状态监测技术的工作原理、优点与不足,并梳理了研究驾驶员疲劳状态的技术路线,提出了建立疲劳数据库的方法、监测驾驶员疲劳状态的方法以及如何应用疲劳监测结果,最后预测驾驶员疲劳状态监测技术未来的发展趋势。

In order to improve vehicle safety and reduce traffic accidents caused by driving fatigue, automobile manufacturers, parts manufacturers and scientific research institutions have been engaged in research on driving fatigue since the 1980s. This paper summarizes the research and application of various driver fatigue state monitoring systems and the driver fatigue state monitoring system equipped with the vehicle models sold by the automobile manufactures, and its working principle, such as the Mercedes-Benz Attention Assist system based on maneuvering behavior to monitor driver fatigue status, Toyota Driver Monitor system monitors driver status based on driver's facial status, eye opening and closing frequency, Ford Driver Alert System uses multi-dimensional information fusion method to monitor driver status, and so on. This paper analyzes the working principle, advantages and disadvantages of various driver fatigue state monitoring technologies, and sorts out the technology roadmap of researching driver fatigue state, and proposes the method of establishing fatigue database, the method of monitoring driver fatigue state and its application principle. Fatigue monitoring results, and authors predict the future development trend of driver fatigue state monitoring technology in the end.
