摘要
为分析车辆跟驰模型的性能和存在的问题,并在试验基础上有针对性地提出模型的关联因素,利用开发的FMSS数值模拟系统,对3种车辆跟驰模型的稳定性、真实性和存在的问题进行了特殊过程下的跟车数值模拟和分析。结合五轮仪跟车试验结果,分析了建立跟驰模型需要系统考虑的问题,提出了一个概念模型。研究表明:所分析的跟驰模型在特殊过程下都是不稳定的跟驰模型,要建立具有良好综合性能的跟驰模型,应引入主观意愿、驾驶环境等不确定的智能因素,建立包含数学、逻辑映射的综合模型。
In order to analyze the properties and problems of car-following models and bring forward the relative factors of model, three car-following models are simulated and analyzed in particular progress by FMSS in this paper. These models are simulated and analyzed in field of stability, truthfulness and existence problem. Combined with the data that comes from car-following experiment with five-wheel test instrument, the matters which should be systematically considered are analyzed and a conception model is put forward. It is indicated in this paper that these models are not stable. For constructing a good model, the factors, such as subjective desire, driving environment etc should be inducted, and the model synthesized by mathematics and logic will be constructed.
