【摘要】：为研究视觉分心对驾驶人转向操作和车道偏离的影响,基于实车道路试验数据,采用统计方法分析视觉分心时驾驶人的分心时长、转向操作和车道偏离的变化特点。选取偏离距离均值、偏离距离方差和偏离幅度3个指标来表征车辆横向偏离程度,对比分析视觉分心过程中及其前后1 s时的车道偏离特点。结果表明:视觉分心时长集中在0.5~3.5 s,比例为87.16%;随着视觉分心时长的增加,驾驶人对方向盘的操作趋势减少;车道偏离发生在分心起始时刻的前或后约0.5 s,以一直偏向同一方向为主,比例为84.49%;车道偏离较视觉分心前后1 s更严重,且偏离程度随着分心时长的增加而增加。
[Abstract]:In order to study the influence of visual distraction on driver's steering operation and lane deviation, based on the real vehicle road test data, the statistical method was used to analyze the characteristics of driver's distraction duration, steering operation and lane deviation. The mean deviation distance, deviation distance variance and deviation range were selected to characterize the degree of lateral deviation of vehicle, and the characteristics of lane deviation during visual distraction and 1 s before and after visual distraction were compared and analyzed. The results showed that the visual distraction time was concentrated at 0.5 ~ 3.5 s, the proportion was 87.16, and with the increase of visual distraction time, the operating tendency of steering wheel decreased with the increase of visual distraction time. The lane deviation occurred about 0.5 s before or after the onset of the distraction, mainly in the same direction, with a ratio of 84.49.The lane deviation was more serious than that before and after the visual distraction, and the deviation increased with the increase of the distraction duration.
