摘要
通过西安市区道路试验获取轿车的行驶特征数据,利用MATLAB建立仿真评价系统,并根据试验数据内嵌建立西安市区道路仿真行驶工况和轿车仿真模型,通过运行仿真获得轿车运行的燃料消耗仿真数据。通过仿真数据与试验数据对比发现,轿车在西安市区道路运行时的瞬时燃料消耗量、累计燃料消耗量的仿真数值与试验数值的平均相对误差均小于4%。因此,利用该仿真方法评价典型城市道路上轿车的燃料消耗可行且有效。
The running data of car was firstly obtained from the road test in the Xi＇an urban area;then the simulation evaluation platform was built by using MATLAB.Based on the road test data,the car＇s simulation model and the driving cycle simulation of Xi＇an city were built on the platform so as to acquire the simulation data of car＇s fuel consumption.The comparison between the simulation data and the test data showed that the average relative error between the instantaneous fuel consumption,the accumulated fuel consumption,and the test data was less than 4%in the Xi＇an urban area.Therefore,it is feasible and effective to use the simulation method to evaluate the fuel consumption of cars on typical urban roads.
