Intelligent ashore control method of amphibious vehicle, wheel lowering system and storage medium

The invention belongs to the technical field of special vehicles, and particularly discloses an intelligent ashore control method of an amphibious vehicle, a wheel lowering system and a storage medium. Comprises: triggering a landing instruction; the hydro-pneumatic suspension executes a wheel laying-down action; in the lowering process of the wheels, the height positions of the wheels and the pressure in a suspension oil cylinder are detected in real time, and when the measured value n of the vehicle terrain clearance supported by the wheels is smaller than the set wheel supporting height base value N or the measured value Pa of the pressure in the oil cylinder is smaller than the set oil cylinder pressure base value P, the vehicle actively recognizes and triggers the wheels needing to be filled with oil; the supporting hydraulic oil cylinders of the corresponding wheels are filled with oil again; and circularly judging the opportunity of needing to charge oil for all wheels, and ensuring that the wheels sup
