The embodiment of the invention discloses a power generation rotating speed determination method for a hybrid vehicle in a series power generation mode. The method comprises the steps that the target series power generation power of the hybrid vehicle is determined; based on the target series power generation power, determining first electric power output by an engine and second electric power of a power generation motor; correcting the first electric power and the second electric power to obtain corrected first electric power and corrected second electric power; and based on the corrected first electric power, the corrected second electric power and the target series power generation power, the target power generation rotating speed of the hybrid vehicle is determined. By correcting the electric power output by the engine and the electric power of the power generation motor, the influence of complex factors on the maximum output power of the engine and the power generator of the hybrid vehicle is reduced, so that the target power generation rotating speed of the engine or the power generator can be accurately determined based on the corrected electric power; the maximum output power of the hybrid assembly is achieved, and the driving requirement of a driver is met.

    本申请实施例公开了一种串联发电模式的混动车辆的发电转速确定方法,该方法包括:确定混动车辆的目标串联发电功率;基于目标串联发电功率,确定发动机输出的第一电功率,以及发电电机的第二电功率;对第一电功率和第二电功率进行修正处理,得到修正后的第一电功率和修正后的第二电功率;基于修正后的第一电功率、修正后的第二电功率和目标串联发电功率,确定混动车辆的目标发电转速。通过对发动机输出的电功率和发电电机的电功率进行修正处理,降低了复杂因素对混动车辆的发动机和发电机的最大输出功率的影响,从而使得基于修正后的电功率可以准确地确定出发动机或发电机的目标发电转速,达到混动总成的最大输出功率,满足驾驶员的驾驶需求。
