摘要
本研究以世界银行HDM-Ⅲ模型中的行驶速度和燃油消耗预估模型为基础,通过油耗试验建立和标定8种车辆的单位油耗关系式,并通过车速调查和采用限速法建立了稳态车速预估模型。在此基础上,建立了8种车辆的油耗-路况关系式和平直路段上的油耗-平整度关系式。供经济分析和评价用。
Based on the modelling methodology given in the HDM-Ⅲ model of the World Bank, a unit fuel consumption prediction model is developed for 8 types of vehicles by fuel consumption tests on flat and straight road sections with various roughness levels, along with the analysis of engine characteristics. Meanwhile, a steady-state speed prediction model is developed by using probabilistic limiting speed approach and by surveying the desired speed of vehicles. Combining these two models, the fuel consumption prediction model for the 8 types of vehicles can then be derived. The fuel consumption-roughness relationships for 8 types of vehicles are offered which can be used for further development of vehicle operating cost model.
