公交驾驶员驾驶行为对油耗的影响及其评价指标

The Effects of Bus Driver's Behavior on Fuel Consumption and Its Evaluation Indicator

基于通过车辆无线远程监控系统采集的天津市某公交线路6位不同驾驶员累计达2.5万km的车辆运行数据,分析了描述驾驶员驾驶行为的车辆相对正加速度、加速踏板行程分布和换挡切换速度分布3个因素对行车油耗的影响。再采用因子分析法将3种影响因素归纳成一个综合评价因子。结果表明,该综合评价因子与行车油耗的相关系数达到0.9,可作为驾驶员驾车油耗的有效评价指标。

Based on vehicle driving data of six drivers on a public bus route in Tianjin city with a total mileage of 25,000km collected by wireless remote monitoring system, the effects of three factors, which describe driver’s behavior, i. e. the relative positive acceleration of vehicle, the distributions of acceleration pedal travel and shifting speed on fuel consumption are analyzed. Then the three factors are summed up into a comprehensive evalua-tion factor by factor analysis. The results indicate that the correlation coefficient between the comprehensive evalua-tion factor and fuel consumption is up to 0 . 9 , so the comprehensive evaluation factor can be used as an effective e-valuation indicator for the driving fuel consumption of drivers.
