The invention discloses a range extender power generation power control method and device, a storage medium and a vehicle. The control method comprises the steps that forced power generation power, current accessory consumption power and power demand power generated when a driver steps on an accelerator are obtained and accumulated, and a first power generation power value is obtained; performing NVH power generation power limitation to obtain an NVH limited power value, and obtaining a second power generation power value by taking the smaller value of the first power generation power value and the NVH limited power value; performing special scene generation power compensation in a special scene to obtain a third generation power value; the target engine rotating speed and the target engine torque are determined in the MAP according to the third power generation power value; and the optimal engine rotating speed is determined according to the engine economical efficiency working point, and when the optimal engine rotating speed is equal to the target engine rotating speed, the optimal engine torque is obtained. According to the method, the NVH problem in a conventional scene can be solved, the power protection problem of the engine in a special scene can also be solved, and the engine can work at the optimal economical working point.
本发明公开了一种增程器发电功率控制方法、装置、存储介质及车辆,控制方法包括:获得强制发电功率、当前附件消耗功率和驾驶员踩油门的动力需求功率并进行累加得到第一发电功率值;进行NVH发电功率限制得到NVH限制功率值,取第一发电功率值和NVH限制功率值的较小值得到第二发电功率值;在特殊场景下进行特殊场景发电功率补偿得到第三发电功率值;根据第三发电功率值在MAP图中确认目标发动机转速和目标发动机扭矩;根据发动机经济性工作点确定最优发动机转速,当最优发动机转速等于目标发动机转速时,得到最优发动机扭矩。本发明既可解决常规场景下NVH问题,亦可解决特殊场景下发动机保电问题,更能使发动机工作最佳经济性工作点。
