摘　　要：为了改善增程式电动汽车的燃油经济性与排放,其搭载的增程器应工作在有限个固定点上。本文中采用Kriging无偏估计方法建立了增程器系统的发电功率与燃油消耗预测模型,并对模型进行了实验验证。经过仿真分析,确定了满足5个发电功率需求的最佳油耗工况点。增程器系统的台架实验和整车实验的结果表明,优化后单个发电功率运行点油耗最大降幅达到了15.96%,而在两种不同的车辆控制模式下整车能耗分别降低了4.62%和3.50%。To improve the fuel economy and emissions of extended-range electric vehicles, range extender should operate at limited fixed points. In this paper, the simulation models for predicting electricity generating power and fuel consumption of range extender system are set up by using Kriging unbiased estimation method and verified by tests. Optimal operating points in fuel consumption meeting five desired electricity generating powers are determined by simulation. The results of range extender bench test and vehicle dynamometer test show that after optimization, the maximum reduction rate of fuel consumption among five operating points for electricity generating power reaches 15.96%, and the vehicle energy consumptions in two different modes reduce by 4.62% and 3.50% respectively.
