基于层次分析法的智能跟车功能评价模型研究

Research on Evaluation Model of Intelligent Vehicle Following Function Based on Analytic Hierarchy Process

围绕智能跟车功能综合评价进行了深入分析和研究,构建智能跟车功能综合评价体系。基于智能跟车功能相关测试标准及专著文献,将预计碰撞时间(TTC)、车头时距(THW)、最大加(减)速度、速度、车道线和道路边缘相对距离、加速度变化率和停车距离作为评价参数,应用德尔菲法(Delphi)对各评价参数与安全性和舒适性的相关性进行专家咨询,应用层次分析法(AHP)将安全性与舒适性作为评价准则,建立一套智能跟车功能的综合评价指标体系。构筑客观安全与主观体验相结合的多维度评估模型,为智能跟车功能综合评价提供评价依据。

This paper has built a comprehensive evaluation model of intelligent vehicle following function based on thorough analysis and research.Time To Collision(TTC),Time To Headway(THW),the most acceleration(deceleration),speed,the relative distance including longitudinal distance and lateral distance are chosen as evaluation parameters in this model according to test standards and monographs.With the help of Delphi method,the correlation between the evaluation parameters and safety/comfort has been calculated from experts’advice.Then a comprehensive evaluation index system of intelligent vehicle following function has been set up based on AHP,so as to construct a multi-dimensional evaluation model.This model combines objective safety with subjective experience,which can provide evaluation basis for the comprehensive evaluation of intelligent vehicle following function.
