摘要
通过对武汉市道路交通状况的调查,选择典型路段进行电动汽车行驶工况研究;测试车辆的行驶速度、转速、油耗和制动踏板力,同期进行车辆流量统计。引入主成分分析法,从采集的原始数据中提取微行程并按加权比例进行工况合成,从而建立武汉市电动汽车行驶工况。
Based on the investigation of the Wuhan city＇s traffic conditions, this paper researches the driving cycles on typical section of a road. The driving speed, rotate speed, fuel consumption and braking force on the footplate of the car are measured and the traffic flow is counted at the meantime. Use the principal component analysis method, extract the microtrip from the original data and combine them according to the weight proportions, the driving cycle of electric vehicles in Wuhan city is established.
