摘　　要：通过几组平直道路上的汽车滑行试验数据,建立了汽车车速和行驶阻力的关系.以汽车等速行驶的驱动力、行驶阻力平衡式及用台架测试的发动机特性参数进行汽车燃油消耗量模拟计算,并用道路试验值进行修正.在平直道路上测量了汽车不同速度点的等速100 km油耗,推导出发动机转速、功率(转矩)、有效燃油消耗率等负荷速度特性参数进行模拟计算,消除了发动机台架试验和汽车上实际使用条件的差异,有更高的模拟精度.The relation between vehicle speed and running resistance was established using the data from several vehicles sliding tests in straight road. Vehicle fuel consumption was simulated with en- gine performance parameters testing on bench and the balance relationship between driving force and running resistance at constant speed, which was amended with the data road testing. Engine charac- teristics parameters, such as speed, power, and efficient fuel consumption rate were deduced with the constant speed lOOkm fuel consumption testing in straight road, differences between bench testing and actual use conditions was eliminated, which improved the precision.
