排放试验驾驶行为与燃油消耗量的关系研究

Study on Relationship between Driving Behavior and Fuel Consumption in Emission Test

针对检测机构测试过程中驾驶行为与燃油消耗量(简称油耗)关系进行了研究分析,首先保持其他试验条件不变,对3名驾驶员的驾驶评价指标循环速度平方根误差(RMSSE)、循环惯性做功改变率(IWR)、距离变化率(DR)数据和车速、油耗曲线做对比试验,并开展了油门开度、车速和油耗关系的测试,得到驾驶行为会对测试结果产生影响的结论后,进一步完成驾驶员驾驶行为一致性的对比测试,其结果表明一致性结果更好的驾驶员,更能保证测试数据的稳定性,以上分析为检测行业驾驶培训及未来的驾驶标准提供了依据。

The relationship between driving behavior and fuel consumption has been studied and analyzed in the detection process.Firstly,the data of driving evaluation indexes such as RMSSE,IWR and DR,speed and fuel consumption curves of three drivers were compared with other test conditions unchanged.The relationship between accelerator pedal opening,speed and fuel consumption was tested,and it was concluded that driving habits would affect the test results.After that,the comparative test of driving behavior consis-tency of the drivers in the laboratory was further completed.The results show that the driver with better consistency results can better ensure the stability of the test data.The above analysis provides a basis for testing the driving training of the industry and the future driving standards.
