摘要
为提高城市道路驾驶人横向避险能力,利用固定基座驾驶模拟器搭建5种典型城市道路危险交通场景,并借助眼动仪采集35名驾驶人的眼动数据和避险操作数据;分别统计并分析驾驶人的视线分布、感知-制动时间、持续制动时间、最大方向盘转角时间和车辆横向位置变化等参数。结果表明：5种场景下驾驶人水平视线基本上都处于中部偏右区域;除场景3外,驾驶人的感知-制动时间均值均在1 s内;在视线无遮挡场景,驾驶人主要通过制动进行避险,反之则以转向和制动相结合的方式进行避险。
In order to improve drivers＇ lateral risk avoidance ability,simulation experiments were carried out. In the experiments,a driving simulator with fixed base was used to build 5 typical dangerous driving scenes of urban roads,and an eye tracker was used to record eye movement data and risk avoidance operation data of 35 drivers. Parameters such as drivers＇ gaze distribution,the perception-brake reaction time,continuous braking time,maximum steering wheel angle time,and vehicle lateral position were statistically analyzed. Results show that the drivers＇ horizontal visual lines are in the middle right area of the visual field in the five scenes,that except for scene 3,the average perception-braking time of drivers is less than 1 second,and that when the visual line is not blocked,the driver mainly adopts the brake to avoid risk,otherwise mainly adopts the operation consisting of steering and braking.
