The existing velocity-time driving conditions used in endurance test fail to consider the impact of throttle opening on fuel consumption test,resulting in a large deviation between measured and actual fuel consumption.The driving condition con-structed by introducing the throttle opening comprehensively considered the influence of load and velocity change on driving fuel consumption.By dividing the driving segments of velocity-throttle opening,the principal component analysis,cluster analysis and correlation analysis were used to screen the driving segments,and the driving segments were spliced to construct the veloc-ity-throttle opening-time three-dimensional curve of working conditions.Compared with the two-dimensional curve of working conditions,the deviation between the measured and actual fuel consumption reduced by 12.673%based on the three-dimension-al curve of working conditions.
