The embodiment of the invention discloses a range extender working point selecting and switching method, device and equipment and a medium, and the selecting and switching method comprises the steps that driving demand information and running state information of a vehicle are obtained firstly, then the target power demand of a range extender is determined according to the driving demand information and the running state information, and the target power demand of the range extender is determined according to the target power demand. Then constructing a working performance optimization function of the range extender; wherein the working performance optimization function comprises at least one to-be-optimized parameter of oil consumption, emission and vibration, and finally selecting a target working point of the range extender according to the target power demand and the working performance optimization function. Wherein the target working point corresponds to the target rotating speed and the target torque of the range extender. By means of the method, the working performance requirements of low oil consumption (high oil-electricity conversion efficiency or high system efficiency), low emission, low vibration and the like are met at the same time, so that the optimal working point and working curve of the range extender can be rapidly and accurately matched, and the effect of selecting and optimizing the working point of the range extender is achieved.

    本发明实施例公开了一种增程器工作点的选取及切换方法、装置、设备及介质,该选取及切换方法首先获取车辆的驾驶需求信息和运行状态信息,然后根据驾驶需求信息和运行状态信息,确定增程器的目标功率需求,之后构建增程器的工作性能优化函数;其中,工作性能优化函数包括油耗、排放和振动中的至少一种待优化参数,最后根据目标功率需求,以及工作性能优化函数,选取增程器的目标工作点;其中,目标工作点对应增程器的目标转速和目标扭矩。利用上述方法,同时兼顾低油耗(高油电转换效率或高系统效率)、低排放、低振动等的工作性能要求,以便于快速准确地匹配出增程器最佳的工作点及工作曲线,实现了对增程器工作点的选取及优化的效果。
