Abstract

Abstract: The sensors of vehicle collision avoidance system are easily interfered by road transport environment when detecting information of obstacles, and therefore missed and wrong detecting are appeared. The causes are analyzed, and the detected information types are classified by their characters. According to the analysis and classification, a model used as an accuracy model for vehicle collision avoidance is to be described. To reproduce the characters of interference, the values of collision-judgment function are simulated by Monte-Carlo method. The experiments are carried out on road transport system simulation and experiment platform (RTSSEP), and the results of which can indicate that the simulation not only availably reappears the implementation of the model, but also supply data for the further detection reliability modeling.

Key words: intelligent transportation, vehicle collision avoidance, reliability model, information detection, simulation method, experimental platform

摘要： 分析了当前车辆避碰系统传感器端在对障碍物信息进行检测时，易受到道路交通环境因素干扰而产生虚报、漏报现象的原因，对车载传感器检测到的障碍物信息进行了性质归类. 在此基础上介绍了车辆避障准确度模型. 采用蒙特卡罗方法模拟车辆在运行过程中的碰撞判定，并依此对模型的仿真算法进行了设计. 整个仿真试验在室内道路交通系统仿真试验平台 (RTSSEP)上实施，结果表明仿真方法能有效模拟障碍物信息准确度模型的执行过程，可为进一步开展建模研究提供信息依据.
