A hybrid power system comprises an engine, a first driving motor, a second driving motor, a gearbox and a motor shell, the first driving motor and the second driving motor are both arranged in the motor shell, and a stator of the first driving motor and a stator of the second driving motor are both fixedly connected to the motor shell. The input end of the gearbox is provided with a first gearbox input shaft and a second gearbox input shaft which are coaxially arranged, the first gearbox input shaft penetrates through the second gearbox input shaft, the output end of the engine is connected to the output end of the first driving motor, and the output end of the first driving motor is connected to the first gearbox input shaft; and the output end of the second driving motor is connected to the input shaft of the second gearbox. The hybrid power system is better in driving experience during gear shifting and power switching, low in cost, high in whole vehicle integration, small in speed reduction in the gear shifting process on a large-resistance road surface, high in gear shifting success rate and free of power interruption during gear shifting. The invention further provides a control method of the hybrid power system and a mining dump truck.
