The invention discloses an efficiency debugging and optimizing method for a range extender system of a new energy hybrid vehicle, which is characterized in that a path from zero power to target power P of the range extender system takes a curve fitted by an optimal fuel consumption curve of an engine and a highest power generation efficiency curve of a generator as a target power track path. According to the method, the optimal power generation efficiency of the range extender system is debugged in multiple modes, the searching time of the optimal efficiency area of the range extender system is obviously shortened, and the range extender system reaches the optimal efficiency area in the optimal way.

    本发明公开了一种新能源混动汽车增程器系统效率调试优化方法,其特征在于:增程器系统的从零功率到目标功率P的途径,按发动机最佳油耗曲线与发电机最高发电效率曲线两者拟合的曲线作为目标功率轨迹路径。本发明实现了多种方式对增程器系统的发电最优效率的调试,明显缩短增程器系统的最佳效率区域的寻找时间,并使得增程器系统以最佳途径达到最佳效率区域。
