摘要: 针对轻型车行驶特征与能耗的关联性进行分析时直接进行大量实测数据比对会造成数据分析时间倍增及比对结果失真。机动车行驶工况是车辆实际 道路行驶特征的集中体现,是分析机动车油耗及排放的重要手段。以私家车和出租车为轻型车研究对象,在采集了大量车辆的实际行驶数据的基础上采用 短行程法为构建方法分别构建了私家车和出租车的行驶工况。最后对所构建的工况的有效性进行了验证,分别比对了所构建的私家车和出租车行驶工况和 实际行驶工况的速度及加速度概率分布,结果显示了良好的一致性,表明了所构建的轻型车行驶工况在表征车辆实际道路行驶特征方面的有效性。

Abstract: In the process of analyzing the correlation between the driving characteristics and the energy consumption of light vehicles, the direct data comparison of a large amount of the measured data resulted in time multiplying of data analysis and distortion of comparison results. Vehicle driving condition was the concentrated reflection of the actual road driving characteristics of vehicles, and an important means to analyze vehicle fuel consumption and emissions.Taking private cars and taxis as the research objects of light vehicles,the driving conditions of private cars and taxis were established by short-distance method based on collecting a large amount of actual driving data of vehicles. Finally, the validity of the driving cycle construction was verified, and the probability distribution of the speed and acceleration of the private cars and taxis driving cycle and the actual driving cycle were compared respectively.The results show good consistency, which indicates that the established driving conditions of light vehicles are effective in representing the actual road driving characteristics of vehicles.

Key words: vehicle engineering, driving characteristics, short trip, light vehicle, driving cycle construction, availability
