摘　　要：混合动力电动汽车在进行能耗经济性评价时,由于试验过程中车辆充电式电量储存系统的电能变化量会影响燃油的消耗,因而将试验标准引入了修正试验程序,以修正后的结果来评价其燃油经济性。为研究修正系数的差异性及其对油耗结果评价的影响,对某一车型进行燃油消耗量修正系数试验并使用获得的修正系数对实测油耗修正。结果表明,修正后的燃油消耗量能真实客观地反映车辆的燃油经济性,但不同车辆得到的修正系数存在较大差异,直接使用可能会使油耗的符合性评价结论完全相反,可指导车辆生产企业在车型油耗公告时选择修正系数及制定油耗申报值。When evaluating the energy efficiency of hybrid electric vehicles,the test standard introduces a modified test procedure to evaluate their fuel economy based on the modified results,as the change in electrical energy of the vehicle's rechargeable electric energy storage system during the test process can affect fuel consumption.To study the differences in correction coefficients and their impact on fuel consumption evaluation,a fuel consumption correction coefficient test is conducted on a certain vehicle model,and the obtained correction coefficient is used to correct the measured fuel consumption.The results indicate that the corrected fuel consumption can truly and objectively reflect the fuel economy of the vehicle,but there are significant differences in the correction coefficients obtained by different vehicles.Directly using the fuel consumption correction coefficient may result in completely opposite conformity evaluations of fuel consumption.The above conclusions can guide vehicle manufacturers in selecting the fuel consumption correction coefficient and formulating fuel consumption declaration values when in the type approval of fuel consumption for the vehicle.
