摘　　要：建立了车辆滑行阻力计算模型。按照GB/T12534-1990《汽车道路试验方法通则》和GB/T12536-1990《汽车滑行试验方法》规定,分别对空载、半载和满载的试验车辆进行了滑行试验,并根据试验数据对滑行阻力计算模型的运动微分方程进行了求解。滑行阻力模型计算得到的百公里油耗值与道路试验值对比表明,所建滑行阻力计算模型有较高的计算精度。This paper has set up a calculation model for automobile coasting resistance.Based on the stipulations in ＇Motor vehicles-General rules of road test method（GB/T12534-1990）and＇Motor vehicles-Coast down-Test method （GB/T 12536-1990） , this paper has carried out coasting tests under conditions of no load,semi-load and full load, and has equated the motion differential equation of coasting resistance calculation model based on tests data.Comparison of fuel consumption per 100 km between calculation results of coasting resistance model and road tests results,shows that the built-up coasting resistance calculation model has high calculation precision.
