基于模糊模型的跟驰车流特性研究

针对有关车辆跟随的传统车流跟驰理论存在的许多不足,分析了跟驰模型存在的问题,提出采用模糊模型来建立局部车流跟随模型,并针对隐性知识问题,提出了采用输入-输出数据对来设计模糊规则,应用权重来解决规则冲突问题并简化规则库.通过实例验证了模糊模型较之跟驰模型的优势.证明模糊模型更能有效地模拟真实的局部车流模型,其将对车辆避撞预警的研究提供理论上的参考价值.

Research on Characteristics of Car-following Based on Fuzzy Model

With the development of the Advanced Vehicle Control System (AVCS),the research of the characteristics of local vehicle platoon became an important topic.The traditional car-following theory has many disadvantages in AVCS,for which the flaw of the car-following model was analyzed.As to the tacit knowledge problems,a fuzzy model was proposed to build local car-following model and the rule base was designed by input-output data.The weight factor was considered to solve the collision of the rule and the rule b...
