摘　　要：以驾驶疲劳状态监测为研究对象,介绍现有几种疲劳检测方法及其优缺点,提出把驾驶行为操作和驾驶员生理指标相结合建立疲劳识别模型的思想。通过大量模拟器驾驶实验,建立驾驶操作和驾驶员生理指标之间的关系模型,并运用最小二乘法对数学模型进行了参数识别。利用驾驶员生理指标能较好判别驾驶员状态特性的特点,找出驾驶操作行为和驾驶状态之间的关系。研究结果有助于建立驾驶操作行为和驾驶员疲劳状态之间的关系模型。Taking the monitoring of vehicle drivers fatigue status as the object of study, some methods for it were introduced. An idea to establish identifying model for fatigue was presented by combining drivers＇operation with their physiological indexes. Through a large number of experiments on vehicle driving simulator, parameters of driving operation and physiological indexes were collected at the same time. Then, a relation model between driving operation and physiological indexes of drivers was set up by analysis; the least square method was used to identify the coefficient of this model. The result shows that using the physiological indexes of drivers can well identify their fatigue status and find out the relationship between their driving operation and their fatigue status. This research is helpful to the establishment of the relation model between driving operation and fatigue status of drivers.
