摘要
基于"中国大型实车路试先行实验(China Pilot-FOT)"所采集的自然驾驶数据,提出了一种开环模型,它可以描述驾驶员紧急变换车道行为。将方向盘转角和方向盘转角变化率作为变道紧急程度的筛选条件,从中筛选出228例紧急变换车道工况。基于最大方向盘转角与最大方向盘转角变化率的线性关系,分析了紧急变换车道的持续时间。利用其中50百分位驾驶数据,来拟合模型参数。使用相关性和显著性检验,验证了真实驾驶数据与驾驶计算模型的关系。结果表明:该模型的输出结果与真实驾驶员操作结果一致性良好。因此,该模型可以描述中国一般驾驶员紧急变道行为。
In order to describe drivers＇ behavior when driver takes an emergency lane-change action, an open- loop model was proposed based on the naturalistic driving data which was collected by the program named China pilot Field Operation Test. Almost 228 lane-change use cases were extracted from the naturalistic driving data. Steering wheel angle rate combined with steering wheel angle were used as filters to classify the different emergency degrees of lane-change. The duration of drivers＇ emergency lane-change was studied based on a liner dependency between the maximum values of both steering wheel angle and steering wheel angle rate. Parameters were fitted by the 50th percentile of the naturalistic driving data collected from lane-change scenarios .The model can be applied in research of Chinese drivers＇ behavior and its values have been proved by both significant test and correlation test. The results of tests show that coherence of the outputs from real driver and the model is good, so the model can well describe Chinese drivers＇ emergency lane-change behavior.
