【摘要】：针对双车道公路弯道轨迹跟踪行为的瞬时多变性,及驾驶人模糊感知与主观决策能力导致的不确定性,通过分析驾驶人在前方弯道线形影响下的驾驶特性,引入转向驾驶行为控制因素,运用多目标模糊优选决策理论,研究了模糊性和主观性对轨迹跟踪行为的影响规律;基于灰色理论,利用主观与客观相结合的权重确定方法,建立了轨迹跟踪模型.选择5处曲线路段进行实地试验,通过试验结果与仿真结果的对比,验证了本文模型的有效性.研究结果表明:行驶轨迹弧长、横向力系数和轨迹侧向偏移是轨迹跟踪行为的控制因素;综合考虑主观与客观因素的权重确定方法,体现了驾驶人在模糊优选决策轨迹跟踪行为中的主观特性.
[Abstract]:In view of the instantaneous variability of track tracking behavior of two-lane highway curve, and the uncertainty caused by the driver's fuzzy perception and subjective decision-making ability, the driving characteristics of the driver under the influence of the curve line in front are analyzed. By introducing steering driving behavior control factors and using multi-objective fuzzy optimal decision theory, the influence of fuzziness and subjectivity on trajectory tracking behavior is studied, and the weight determination method combining subjective and objective is used based on grey theory. A trajectory tracking model is established. Five curve sections were selected for field test, and the validity of the model was verified by comparing the experimental results with the simulation results. The results show that the trajectory arc length, lateral force coefficient and trajectory lateral migration are the controlling factors of trajectory tracking behavior, and the weight determination method considering subjective and objective factors synthetically. It reflects the subjective characteristics of the driver in the trajectory tracking behavior of fuzzy optimal selection decision.
