摘　　要：应用车载油耗实时测试系统,在长春市不同路段、不同时段进行了实时油耗测试实验。根据实验结果分别建立了平峰期和高峰期的平均速度油耗模型、不同道路类型下的速度油耗模型以及不同速度、不同加速度下的瞬时油耗模型。通过其他道路实验对模型进行了验证,结果表明,这些模型能够较好地反映实际道路上车辆燃油消耗的变化情况,可以用来预测车辆在城市道路行驶时燃油消耗。Real time fuel consumption was experimentized in different urban roads and time of the city of Changchun by using the car fuel consumption real time testing system which was built for this research. The average fuel consumption model based on velocity during peak and flat period, the fuel consumption model which was based on velocity on different types of roads and the instantaneous fuel consumption model based on different velocity and acceleration were set up according to the experimental results. At last, the corresponding fuel consumption models were validated through other experiments. The results showed that the models can reflect the fuel consumption change of vehicle on the urban roads and provide an efficient way for accurately forecasting the states of vehicle fuel consumption on the different urban roads.
