Abstract: Aiming at the driver' s operation behavior during eyes off road , non-contact eye movement tracker , lane mark detect system , CAN bus data capture device and other instruments were used to set up natural driving test vehicle. Driving behavior data and vehicle running data of some drivers in real road conditions were co!lected by using this test vehicle. Data analysis results shows that during driver' s eye off road , the average of steering angular velocity is O. 325 ( 0) / s , and it has significant difference of the normal steering angular velocity , which is O. 853 ( 0) / s. With the increasing time of eye off road , the trend of vehicle running away the center line of lane becomes evidently. And drivers wi!l release the accelerate pedal with the increasing time of eye off road in order to improve the control degree of the vehicle.

摘要： 针对驾驶人视线离开前方区域时的操作行为特性，利用非接触式眼动仪、车道线监测系统、CAN总结数据采 集卡等搭建了自然驾驶试验车，对多名被试驾驶人进行了实际道路自然驾驶试验。对数据进行分类统计的结果表 明:当驾驶人的视线离开前方区域时，方向盘转动角速度的均值为0.325(0)/s，与正常情况的0.853(0)/s相比，存 在显著差异;车辆偏离车道中心线的趋势随视线离开前方时间的增加而逐渐明显，驾驶人更倾向于释放加速踏板以 增加对车辆操控的把握程度。
