摘要： 为了明确分心过程中的车道偏离规律,从而降低分心驾驶时因车道偏离引发的碰撞事故,在实际道路中进行行车试验,对参试的12名驾驶人共记录了398次分心过程的车辆运动状态数据。选取车道偏离的均值、方差和偏离幅度来表征车道偏离的程度,分别对该3项统计指标与分心时长进行相关性检验和拟合分析,并按时长分组对比分析分心驾驶与正常驾驶时的该3项指标,得到了车道偏离随驾驶分心时长的变化关系。结果表明:驾驶分心过程中的车道偏离高于正常驾驶;车道偏离随着驾驶分心时长的增加而增大,并且增大速度越来越快;当分心时长超过3.0 s时,车辆的车道偏离量在短时间内迅速增大。

Abstract: To figure out the law of vehicle lane departure during distracted driving and to reduce the collisions caused by lane departure, twelve drivers participated in road driving test; and the vehicle movement states of 398 distracted driving samples were collected. The means, the variances and amplitudes of the lane departure distances were selected as the indicators to characterize the level of lane departure. The correlation test and the fitting analysis between the distracted driving time and the three indicators were carried out. By analysis of the variation of the three indicators during common driving and distracted driving, the relationship between distracted driving time and lane departure was derived. The results indicate that the lane departure during driving with distraction is larger than that without distraction. The lane departure increases with the distracted driving time, and it increases more and more quickly. When the distraction time exceeds 3.0 s, the vehicle lane departure rises rapidly in a short time.
