摘　　要：在不同的试验条件下,采用实验室碳平衡法和道路实时测试法对轻型汽车燃油经济性进行实证研究,计算了测试系统的不确定度及其置信区间,分析了测试方法之间的相关性。燃油消耗的变化趋势是试验场高于实验室,实际道路又高于试验场。In different testing conditions, an experimental study is performed on fuel economy of a light vehicle with both carbon balance calculation method in laboratory and real time measurement on proving ground. The degree of uncertainty and confidence interval of measuring systems are calculated and the correlativity between different methods is analyzed. The results show that the fuel consumption on proving ground is higher than that in laboratory.
