基于驾驶员认知过程的车辆跟驰模型的建立

基于认知心理学的有关知识，提出一种将驾驶员的直觉、分析和推理三者相结合的驾驶员认知结构基本框架，在此框架体系下对车辆跟驰过程中驾驶员的认知过程进行了详细的分析；结合五轮仪试验系统采集的数据，采用因子分析法确定出对驾驶员的车辆跟驰信息提取过程有独立作用的4个因素，包括前车位移、前车速度、前车加速度和后车位移，相应地将驾驶员认知过程划分为4个阶段，构建了跟驰过程中驾驶员的认知结构模型，并对各个阶段做出了具体分析，建立了相应的车辆跟驰模型。仿真结果表明，基于驾驶员认知过程的跟驰模型可以较好地揭示跟驰过程中的驾驶行为。

A Car-following Model Based on Drivers' Cognition Behavior

Based on the knowledge of cognitive psychology,a kind of drivers' cognition frame which combines intuition,analysis and inference was proposed,the drivers' cognition behavior in the process of car-following was analyzed under the frame.And based on the data collected by Five-wheel system,four factors including speed,acceleration,distance of the former vehicle and distance of the following vehicle which have independent role in the process of driving information extraction were determined by using factor analysis.Accordingly,the cognition process of drivers was divided into four phases and a cognition structure model for drivers' car-following behavior was developed.Each phase was analyzed concretely,and a car-following model was developed based on drivers' cognition behavior by mathematical method.Simulation result shows that the car-following model developed can properly reflect drivers' behavior in car-following course.
