现有的用于续航测试的车速-时间汽车行驶工况未能考虑油门开度对油耗测试的影响,导致测定油耗相较于实际油耗偏差较大.引入油门开度构建汽车行驶工况可以综合考虑负荷与车速变化对行车油耗的影响.通过划分车速-油门开度行驶片段,利用主成分分析、聚类分析和相关性分析等方法筛选行驶片段,拼接行驶片段构建车速-油门开度-时间三维工况曲线.研究发现,相较于二维工况曲线,基于三维工况曲线测定油耗与实测油耗的偏差减少了 12.673%.
Construction of Vehicle Endurance Test Condition by Introducing Throttle Opening
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.
