The invention discloses a power transmission system of a hybrid power forklift and a control method thereof. The power transmission system comprises an engine assembly, a transmission system, a walking system, an operation system, a whole vehicle controller and a control system. The engine assembly comprises a fuel engine assembly, an ISG motor assembly and a storage battery assembly, the ISG motor assembly drives the fuel engine assembly to be started, and meanwhile the traveling system and the operation system are driven through the transmission system. The fuel engine assembly drives the ISG motor assembly to generate power and charge the storage battery assembly; the control system controls the clutches and the brakes through the vehicle control unit to achieve switching of the controlmodes. The fuel oil engine has the beneficial effects that the fuel oil engine can work in a high-efficiency area, the ISG motor assembly assists the fuel oil engine in working under severe working conditions, so that emission and oil consumption of the fuel oil engine are controlled, and the ISG motor assembly serves as a generator to charge the storage battery assembly when the fuel oil enginehas surplus power.
