The invention discloses a hybrid power system and a power dividing type control method of the hybrid power system, and the method comprises the steps: obtaining vehicle state information; the vehicle state information comprises an energy storage state of a vehicle-mounted battery, a vehicle speed state and a torque demand state; setting a corresponding working mode according to the vehicle state information; corresponding to the working mode, the first power unit, the second power unit and the third power unit are controlled to participate in the transmission connection state of the gearbox unit, and the working states of the first power unit, the second power unit and the third power unit are controlled; according to the change of the energy storage state or/and the vehicle speed state or/and the torque demand state of the vehicle-mounted battery, working modes are switched; and according to the working mode switching, working state switching of the first power unit, the second power unit and the third power unit is controlled. Through the scheme, the transmission connection state is finely matched, and the energy utilization rate of the whole vehicle is improved.
