摘　　要：国六排放法规中提出了多种道路载荷的测量方法,该文选取滑行试验法和计算法两种方法进行对比研究。并基于两组道路载荷进行WLTC对比试验。结果表明滑行法求得的滑行阻力要小于计算法求得的道路阻力。在排放物方面,气态排放物和颗粒排放物滑行法都要比计算法结果更让好近20%。在油耗方面,在各个阶段及综合油耗上,滑行法都比计算法更低,综合油耗更是低了0.29L/100km。In the China VI emission regulations,a variety of road load measurement methods are proposed,and this paper selects two methods:taxi test method and calculation method for comparative study.Based on the two sets of road loads,the WLTC comparison test was carried out.The results show that the sliding resistance obtained by the sliding method is less than the road resistance obtained by the computational method.In terms of emissions:the gaseous emissions and particulate emissions sliding method are nearly 20%better than the calculation method.In terms of fuel consumption:in all stages and comprehensive fuel consumption,the sliding method is lower than the calculation method,and the comprehensive fuel consumption is 0.29L/100km lower.
