The invention discloses a vehicle pump control servo suspension system and a control method thereof. The system comprises a plunger type cylinder, a pressure sensor, a hydraulic control one-way valve, a three-position damping switching valve, an energy accumulator, a controller, a servo motor, a two-way pump, an overflow valve, a one-way valve, a pressurization oil tank and a position sensor, is highly integrated and can be integrally and independently installed and used. The suspension damping has three selectable modes, namely a high-speed movement mode, an urban transportation mode and a mountain road surface mode; meanwhile, suspension is adjusted through an independent closed pump control servo system, a servo motor drags a bidirectional hydraulic pump to adjust and control the extension length of a plunger cylinder in real time, the suspension system can be actively adjusted according to the road condition and speed of vehicle running, it is guaranteed that the whole vehicle is kept horizontal in the running process, and the driving comfort of the vehicle is improved. According to the invention, the reliability is high, the insensitivity to oil pollution, the maintainability and the integration are improved, and the throttling loss is reduced.
