The invention relates to the technical field of high-pressure auxiliary power systems of new energy vehicles, and provides an air compressor power-assisted steering integrated system for a new energy vehicle and a control method. The system comprises a vehicle control unit, a driving motor assembly, an air compressor air pump assembly and an air storage tank, the driving motor assembly, the air compressor air pump assembly and the air storage tank are all connected with the vehicle control unit, a pneumatic clutch is additionally arranged between the driving motor assembly and the air compressor air pump assembly, and an exhaust port of the air compressor air pump assembly is connected with the air storage tank; the vehicle control unit judges the air pressure in the air storage tank, when the air pressure is not larger than a set threshold value, the pneumatic clutch is controlled to be closed, connection with the driving motor assembly is completed, and the driving motor assembly drives the air compressor air pump assembly to work. And when the air pressure is larger than a set threshold value, the pneumatic clutch is controlled to be disconnected, separation from the driving motor assembly is completed, and the air compressor air pump assembly stops working.
