通过对驾驶员眼睛生理特征的监测来判断驾驶员的疲劳状况是当前疲劳评判研究的热点之一。基于眼部行为指标来进行驾驶疲劳监测研究，分析驾驶过程中驾驶员眼动的瞳孔直径、眨眼时间均值的变化规律。在原有的眨眼时间均值指标的基础上，提出瞳孔直径包络值指标，并与原有的眨眼时间均值指标进行实验验证分析。结果表明，瞳孔直径包络值指标可以有效地用于客观评价驾驶员的疲劳程度。

The determination of the status of the driver fatigue by detecting the physiological characteristics of the driver’s eyes is one of the hot‐spots of fatigue evaluation studies .With eye behavioral indicators for driving fatigue monitoring ,the driver’s pupil diameter changes and the variation of the average of blink time during the process of driving were analyzed .On the basis of original indicators (the average of blink time) ,pupil diameter envelope indicators were proposed and experimentally validatled .The results show that the driver’s pupil diameter envelope indica‐tor can be effectively used to objectively evaluate the degree of fatigue .
