基于驾驶模拟实验获取驾驶行为数据,针对驾驶行为数据实时性强、稳定性差、连续变化等特点,引入图谱表达方法,通过图谱时间基元、空间基元及排列组合形式等要素描述驾驶行为变化过程,构建形成驾驶行为特征图谱,实现驾驶行为变化过程的直观表达.研究成果为精确解析驾驶行为特征提供新的思路和解决办法,并为更加针对性地优化驾驶员驾驶行为提供参考和依据.

Driving behavior is one of the key factors that influences motor vehicle safe,green and efficient operation. To apply driving behavior optimization more effectively,it is necessary to grasp its characteristics accurately. Dependent on the driver performance data collected by driving simulator platform,graph-based method was adopted to describe the driving behavior with features of highly realtime,poorly stable and continuously changeable. Through constructing time element,spatial element and ordering their combination,the driver performance graph was established and thus the change process of time and spatial characteristics of driving behavior was expressed intuitively. The study results provide a new insight to analyze the driving behavior features and lay a foundation to improve driving behavior more specifically.
