The embodiment of the invention relates to a control method of a power-assisted steering system, the power-assisted steering system and a vehicle with the power-assisted steering system. The power-assisted steering system comprises an oil source, a switching valve, a first hydraulic pump, a second hydraulic pump and a power steering gear. The switching valve can be switched between the first hydraulic loop and the second hydraulic loop; the power-assisted steering system comprises a second control unit and a first control unit; the control method comprises the steps that the second control unit and the first control unit jointly confirm that the actual vehicle speed is within a first preset vehicle speed range; the second control unit confirms that the actual flow is within the first preset flow range, and the second control unit controls the switching valve to be switched to the first hydraulic loop. The control method of the power-assisted steering system, the power-assisted steering system and the vehicle provided by the embodiment of the invention have the advantage that the control program is not easy to fail.
