汽车行驶路况识别与划分方法研究

Study on Identification Method of Automobile Road Classification

为调研汽车使用路况,真正了解现场路面信息,研究了基于国际平整度指数(IRI)的路面等级便捷识别与划分方法。建立IRI识别路面等级的数学模型,通过道路模拟试验结果进行有效性验证,构建通过样车简配传感器方案及等里程分割方法识别路面等级及其里程分布,结果表明,基于IRI识别路面等级结果与功率谱密度数据吻合良好,所有的技术方法能够快速获取路况及其分布的信息,具有良好的可操作性、有效性。

In order to investigate the road conditions of automobile and truly understand the road information,a convenient identification method of road class based on IRI is studied.The mathematical model of IRI to identify the road class is established,and the effectiveness is verified by the road simulation test results.The method of identifying the road class and its mileage distribution through the simple sensor scheme of the sample vehicle is constructed.The results show that the technology and method studied in this paper is operable and effective.
