汽车驾驶疲劳分析及其监测

为了揭示驾驶员疲劳驾驶导致交通事故的根本理论原因，本文分析了驾驶疲劳的形成过程及其机理。基于人因工程学角度，以疲劳相关理论为基础，构建了承担驾驶负荷的驾驶员身体系统，并把驾驶行为分为三个阶段，把每一阶段所产生的疲劳严格区分为精神疲劳和体力疲劳。根据驾驶疲劳的程度，把驾驶员的疲劳状况分为了四类，建立了驾驶疲劳累积模型。根据对驾驶疲劳形成的系统分析，概括了现阶段疲劳驾驶监测技术的研究方向，并提出了对疲劳驾驶监测技术的发展趋势和应用前景的建议。

Analysis and Monitoring of Driving Fatigue

In order to reveal the theoretical reasons from the traffic accidents are caused by fatigue driving,this paper analysis the formation and mechanism of driving fatigue. From the point of Human Factors Engineering, the driver＇s physical system on bearing the driving load was constructed based on fatigue theory. In addition, the driving behavior was divided into three stages. And the fatigue of each stage was strictly divided into mental fatigue and physical fatigue. Ac cording to the extent of driving fatigue, the status of driver＇s fatigue was divided into ibur types, and a cumulative mode in driving fatigue was built. Under analysis of driving fatigue formation, a brief summary on present research detection of the fatigue driving monitoring methods is made. Furthermore, some suggestions on developing trends and the application prospects of monitoring methods for fatigue driving are given.
