汽车驾驶人感知-决策-校正行为模式

为了全面地了解汽车驾驶人在驾驶过程中的行为特性,对驾驶人操作行为的信息感知、轨迹决策和操作校正3个阶段的行为反应进行了分析,在不同通道宽度条件下进行了车辆行驶试验,记录驾驶人的眼睛运动、操作行为以及车辆的运行速度变化等数据。结合试验数据,对驾驶人第一次感知障碍物存在的位置、第一次采取制动措施的位置和3个操作阶段用时所占比例进行了对照分析。研究结果表明:随着通行条件逐渐困难,驾驶人用于信息感知的时间比例减少,而用于操作校正的时间比例增加。

Experiment on perception-decision-adjustment operation mode of automobile drivers

In order to know driver's operation characteristics well in driving,based on the analysis on the three stages of automobile driver's operation which are information perception,track decision and operation adjustment,the experiments of vehicles running on passage ways with various widths were carried out,and the datum such as driver's eye movements,operation behaviors and vehicle speeds were recorded.According to the experimental datum,the locations of driver's first time perceiving obstructions,the locations of driver's first time braking and the time proportion of the three stages in different passageway widths conditions were compared.The results show that with the passing condition becomes worse,drivers use less time to percept information and more time to operate and adjust the vehicle.7 tabs,2 figs,10 refs.
