摘要
针对驾驶人模型建模中驾驶人的感知、决策和操纵3个关键行为,通过对转向盘转角进行傅里叶变换,在频域上分析行驶轨迹和车速对驾驶人转向操纵动态特性的影响。采用Matlab建立了人车闭环仿真模型,分别在低速60km/h和高速100km/h下进行了蛇形试验和双移线试验仿真,并且在湖州的普通公路和高速公路上进行了实车试验,对比了直线行驶与弯道行驶下的驾驶人转向操纵动态特性。研究结果表明:随着速度增加转向盘转动频率增加,频率成分越高,转向修正幅度越大;在相同速度、不同弯道转角时,转向频率分布基本相同,但是随着弯道转角的增加,转向盘转角幅值明显增大;直线行驶工况下,转向盘转角幅值明显降低。综合分析,道路线型和行驶车速对转向盘转角动态特性影响较大。
To the three key driving behaviorson driver＇s perception, decision-making and manipulation concerned inDriver modelling, This paper concernson how driving path and speed influence dynamic characteristics of driver steering behavior infrequencydomain by Fourier transform. By virtue of simulation on Pylon course slalom and Double Lane Change testunder 60 km/h and 100 km/h, and dailydrivingtest on ordinary highway and super highway in Huzhou, comparing dynamic characteristics of driver steering behavior under straight and curve, the results show that steering wheel angle frequency component and steering correction magnitude increase with speed. There is little difference in steering wheel angle frequency distribution with same speed and different curve. However, steering wheel angle magnitude increases obviouslyas the curve becomes sharp. Steering wheel angle magnitude reduces sharply under straight. Generally, road alignment and speed have large influence on the driver＇s steering dynamic behavior. 1 tab, 8 figs, 19 refs.
