摘要
为研究在弯道路段行驶过程中驾驶人的安全驾驶特性,招募30名驾驶人开展模拟驾驶试验。利用DLab驾驶人因记录分析系统采集弯道行驶过程中驾驶人的车辆操作数据,用face LAB 5非接触式眼动仪同步采集驾驶人的眼动数据,探讨弯道半径对驾驶人视觉及操作模式的影响。结果表明：水平方向上驾驶人的视线主要集中在[-10°,10°],水平视角均值与弯道半径成二次函数关系,并随着弯道半径增大驾驶人的水平视线向右偏移;在操作模式方面,转向盘转角与弯道半径成负相关,车辆横向位置与弯道半径的关系不明显。驾驶人弯道行车时需要及时关注弯道一侧的交通信息,并同时操纵车辆沿弯道轨迹行驶。
In order to research drivers＇ driving safety features in the process of curving driving,driving simulation experiments were carried out with 30 testees. During the experiments,the testees＇ operation data and the eye movement data were collected using DLab and the face LAB 5 non-contact eye tracker respectively. Influences of curve radius on their visual search and operational mode were studied. Results show that the horizontal visual line concentrated in [-10 ° to 10 °],the mean of the horizontal fixation angle is a quadratic function relation of the curve radius,that as the curve radius increases,their horizontal fixation angle shifts to the right,that in terms of operation mode,there is a negative correlation between the steering wheel angle and the curve radius,that the relationship between vehicle lateral position and the curve radius is not obvious,and that drivers should pay attention to the traffic information on the curve side and control the vehicle driving along the curve.
