摘要
为研究驾驶员在高速行车时的跟车特性,基于实车试验采集驾驶员高速公路上的自然驾驶跟车数据,通过Matlab/Simulink联合CANape软件对数据进行跟车判定与筛选,并对驾驶员在加减速以及稳速跟车阶段的跟车特性进行分析。研究结果表明:驾驶员在高速公路跟车过程中跟车间距随车速升高而增加;在稳速及加减速跟车时,跟车间距呈现螺旋状变化;自车加速度与跟车时距存在一定关联,而与自车车速、跟车间距没有明显相关性。研究结果可为自适应巡航系统及驾驶员跟车仿真研究提供参考依据。
In order to study the driver′s follow-up characteristics during the high-speed driving,the Matlab/Simulink and CANape software are used to judge and screen the natural driving data based on the real-car test to collect the follow-up data of the driver′s natural driving on the expressway.Then the follow-up characteristics are analyzed in the follow-up phase of the driver accelerating or decelerating and keeping the speed.The test results show that the follow-up distance increases with the increase of the driving speed during the follow-up process on the expressway;the follow-up distance shows a spiral change at the steady speed and acceleration or deceleration;there is a certain correlation between the acceleration of driver′s own car and follow-up distance,and there is no obvious correlation with the speed of driver′s own car and follow-up distance.The results can provide important reference for the adaptive follow-up system and the research of driver′s follow-up simulation.
