The invention relates to a torque control method and device of a hybrid power system, a vehicle, equipment and a medium, and the method comprises the steps that when a driving mode of the hybrid power system is a series mode, the torque change slope range of an engine and the rotating speed change slope range of a generator are determined according to the driving demand power change determined by the driving wheel end demand torque; the engine torque and the generator rotating speed are controlled to change according to the adjusted corresponding slope change ranges, so that the actual engine torque and the actual generator rotating speed are gently changed to respective targets; and when the driving mode of the hybrid power system is a parallel mode, the torque change slope range of the driving motor is determined according to the driving demand torque change determined by the driving wheel end demand torque, the torque of the driving motor is controlled to change according to the adjusted corresponding slope change range, and the actual torque of the driving motor is gently changed to the target.
本发明涉及一种混合动力系统的扭矩控制方法、装置、车辆、设备及介质,该方法包括:在混合动力系统的驱动模式为串联模式时,根据驾驶轮端需求扭矩所确定的驾驶需求功率变化确定发动机扭矩变化斜率范围和发电机转速变化斜率范围,并控制发动机扭矩和发电机转速分别按照调整后的对应斜率变化范围进行变化,使发动机实际扭矩和发电机实际转速平缓变化至各自的目标;在混合动力系统的驱动模式为并联模式时,根据驾驶轮端需求扭矩所确定的驾驶需求扭矩变化确定驱动电机扭矩变化斜率范围,控制驱动电机扭矩按照调整后的对应斜率变化范围进行变化,使驱动电机实际扭矩平缓变化至其的目标。
