基于运行数据的PHEV工作模式辨别与能耗分析

Working Mode Identification and Energy Consumption Analysis Based on PHEV Operation Data

针对某款插电式混合动力汽车(Plug-in Hybrid Electric Vehicle,PHEV)所能获取的运行数据,基于时序关联和划分的分析方法,提出了一套对PHEV进行工作模式辨别和能耗分析的方法。对运行数据进行预处理,筛选出有效数据,提出利用运行数据对车辆的工作模式进行辨别的方法,针对不同的工作模式,分别研究PHEV整车能耗的分析方法。依据某批次真实的PHEV运行数据,利用该方法分析该款PHEV在各个工作模式下的实际整车能耗情况,最终对PHEV的动力系统提出改进建议。

Based on the method of temporal association and division, a set of methods for working mode identification and energy consumption analysis were put forward according to the actual operation data obtained from a plug-in hybrid electric vehicle （PHEV）. Firstly, the data was preprocessed in order to select valid data. Then, the method of using the vehicle operation data to identify the working mode was proposed. Finally, the energy consumption analysis methods were researched respectively for different working modes. At the end of the paper, based on a set of real PHEV operation data, the energy consumption of the PHEV was analyzed under various working modes and some suggestions to improve the power system of PHEV were put forward.
