The invention provides a method and system for constructing a vehicle driving condition of an urban elevated road, and the method comprises the following steps: obtaining the road condition information of the urban elevated road; determining an urban elevated test road in the urban elevated roads according to the road condition information; obtaining driving data of the test vehicle on the elevated test road; dividing the driving journey of the test vehicle on the elevated test road into a plurality of short journeys according to the driving data; calculating characteristic parameters of each short stroke according to the characteristics of the urban elevated test road; and constructing a vehicle driving condition according to the characteristic parameters and the driving data of the short journey. According to the method, the actual traffic condition of the urban elevated road can be truly and accurately reflected, so that the vehicle driving working condition of the urban elevated road can be constructed, and the defect that the traditional driving working condition cannot be suitable for all regions is overcome.
本发明提供了一种城市高架道路的车辆行驶工况构建方法和系统,其中,所述方法包括以下步骤:获取城市高架道路的路况信息;根据路况信息在城市高架道路中确定城市高架试验道路;获取试验车辆在高架试验道路上的行驶数据;根据行驶数据将试验车辆在高架试验道路上的行驶行程划分为多个短行程;根据城市高架试验道的特征计算每个短行程的特征参数;根据短行程的特征参数和行驶数据构建车辆行驶工况。本发明能够真实准确地反映城市高架道路的实际交通情况,从而能够构建城市高架道路的车辆行驶工况,以弥补传统行驶工况无法适用于所有地区的不足。
