<p>A hybrid drive system and a control method thereof are provided. The hybrid drive system comprises a six-stroke engine (7), generators (1, 6), and two motors (4, 12) with different power. The two motors drive front wheels and rear wheels, alone or together. The engine and a lower power motor connected coaxially with the engine form an arrangement of front engine front drive or rear engine rear drive instead of the engine running alone, a higher power motor forms a corresponding arrangement of rear engine rear drive or front engine front drive. Selections of the driving mode of a vehicle, the gear of the engine and the interrupted oil supplying cruise are performed by a vehicle control unit instructed by an instruction keyboard. The advantage of the present invention is that the energy utilization of the vehicle and the thermal efficiency of the engine is high, the mechanism of the vehicle is simplified, for example, a pedal throttle mechanism, a pedal clutch, a transmission and a transfer case are canceled, and therefore the failure rate and manufacturing cost of the vehicle and the complexity of a control system are reduced, the safety factor is improved, and the product has high performance cost ratio.</p> |
