The invention relates to the field of vehicle suspension devices, in particular to a control method of a pure-electrically-distributed-type multi-wheel moving platform of an intelligent control hydraulic suspension device. The control method comprises the following steps that a rotating speed sensor, a distance sensor and an image sensor transmits information to a controller in real time; the controller controls the hydraulic oil quantities of rod cavities and rodless cavities of main hydraulic cylinders and the sub-hydraulic cylinders, and thus extending and retracting of piston rods of all the hydraulic oil cylinders are controlled; and the piston rods operate in the mode that the piston rods are extended on the groove road surface, retracted on the bulged road surface, and are located in the middle on the normal road surface. Each electric vehicle wheel main hydraulic cylinder is externally provided with the corresponding four wholly symmetrically arranged sub-hydraulic cylinders, extending, shortening and inclining of the hydraulic suspension device can be achieved through matched use of the five hydraulic cylinders, the hydraulic suspension device constituted by five hydraulicmechanisms has the buffering and damping effects on whole electric vehicle wheels and even the whole moving platform, and the problem that in the working process of the main hydraulic cylinders, theperipheries of main hydraulic rods are slightly shaken due to transverse force is effectively solved.
