| 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: | Considering the complexity of horizontal alignment in curves, and the uncertainty of steering behavior resulting from drivers' fuzzy perception and subjective tendency, the control factors of steering behavior were introduced by analyzing drivers' driving characteristics which are influenced by road alignments ahead. The multi-objective fuzzy optimization decision theory was used to study the influence of fuzziness and subjectivity on steering behavior. Then a mathematical method for modeling driver's trajectory tracking behavior was established using the weight determination method that is based on the gray theory and combines subjectivity with objectivity together. In addition, field experiments in five curves were carried out, and the modeling method was verified to be feasible by comparison of experimental and simulation values in trajectory curves. The results show that the length of trajectory, lateral force coefficient, trajectory's lateral offset are control factors of trajectory tracking behavior; and driver's subjective characteristics in fuzzy optimal decision making trajectory tracking behavior can be reflected by the weight determination method combing subjectivity and objectivity. |
