The NEDC、FTP75and WLTC cycle fuel consumption test were carried out in a stabilized gasoline car with three different driving ways including smooth, rough and normal driving by the same driver. Based on the evaluation of energy rating (ER), distance rating (DR), energy economy rating (EER), absolute speed change rating (ASCR), root mean squared speed error (RMSSE) and inertia work rate (IWR), the rationality of the boundary conditions of fuel consumption test were obtained through the analysis and calculation of the above evaluation index and the change of fuel consumption of each test. Smooth and rough driving both resulted in the regular change of evaluation index in FTP75 and WLTC test. However, the different driving way had little effect on fuel consumption in NEDC test. The boundary conditions of fuel consumption test were obtained as below. When ER was in the range of (0.25±0.47)%, ASCR was in the range of (1.20±0.97)%, RMSSE was in the range of (0.85+0.15)km/h, IWR was in the range of (2.15±1.27)%,the driving ways of the WLTC cycle fuel consumption test were reasonable. For the cycle of FTP75, the reasonable driving ways of fuel consumption test ought to make sure that EER, ASCR, RMSSE and IWR ranged among (-0.09±0.69)%, (-0.59±0.42)%, (0.88+0.34)km/h and (-0.69±1.66)% respectively.
