The invention relates to a multi-shaft suspension lifting hydraulic system, a control method and an automobile. A hydraulic oil tank is communicated with a hydraulic oil pump, and the hydraulic oil pump is connected with a rear vehicle posture valve through two hydraulic oil ways and connected with a front vehicle posture valve through the other two hydraulic oil ways. The rear vehicle posture valve is respectively connected with a right rear manual holding valve and a left rear manual holding valve; the front vehicle posture valve is connected with a right front manual holding valve and a left front manual holding valve, and the right rear manual holding valve and the left rear manual holding valve are connected with rear axle hydro-pneumatic springs through hydraulic oil ways provided with axle manual holding valves and axle electric control holding valves respectively. The right front manual holding valve and the left front manual holding valve are connected with the front axle hydro-pneumatic springs through hydraulic oil ways provided with the axle manual holding valves and the axle electric control holding valves respectively. The front, rear, left and right independent hydraulic oil ways can be conveniently and rapidly adjusted in front, rear, left and right heights; the height is adaptively adjusted according to the empty and heavy load conditions, the comfort is good, and the reliability is high under the heavy load condition.
