生理疲劳和心理疲劳对车辆驾驶的影响对比

针对现有疲劳驾驶预警和干预技术研究鲜有对生理疲劳和心理疲劳进行区分考虑的问题，为对比这两类典型疲劳态对驾驶员车辆驾驶过程的事故倾向影响，分别从性别、年龄和驾龄的角度分3批次共招募90位驾驶员进行状态诱发和驾驶实验。结果表明:尽管生理疲劳和心理疲劳都会如传统研究所述导致各驾驶员的驾驶违规倾向增加和驾驶能力降低，但是二者对于各类别驾驶员的驾驶影响程度和规律存在差异甚至迥异。研究疲劳驾驶相关问题时有必要首先判断驾驶员是生理疲劳还是心理疲劳，这是一个被普遍忽视而又可能影响研究结论准确性和有效性的重要因素。

Comparison of influence on vehicle driving by physical fatigue and mental fa-tigue

In view of the problem that the existing research on early warning and intervention technologies of fatigue driving have scarcely considered to distinguish the physical fatigue and mental fatigue, in order to compare the accident tendency influence of these two kinds of typical fatigue states on the vehicle driving process of drivers, totally ninety drivers in three batches considering the gender, age and driving years respectively were recruited to carry out the fatigue state induction and driving experiments. The results showed that although both physical fatigue and mental fatigue will result in the increase of driving violation tendency and the decrease of driving ability of the drivers, which is same as what the traditional research have stated, the influence degree and law of these two fa-tigue states on each type of the drivers may be quite different. Therefore, it is necessary to distinguish whether the driver was in physical fatigue or mental fatigue at first when studying the related problems of fatigue driving, which has great influence on the accuracy and validity of the research conclusion but hasn't attracted enough atten-tion yet.
