The invention discloses a high-and-low pressure chamber closed-loop gas path electronic controlled air suspension system, comprising solenoid valves, an air compressor, a high pressure chamber, a low pressure chamber, air springs, pressure sensors, height sensors, an EUC (electronic control unit) and a connecting line. As the low pressure chamber is added, the gas path closed-loop air suspension system is formed. Thus, compressed gas discharged by the air springs can be recycled; energy loss in the process of gas release is avoided; and the body height adjustment performance in the processes of filling and release can be improved. Through the implementation of a control strategy of the EUC of the system, pressure of the high pressure chamber and pressure of the low pressure chamber can be maintained always within the range of preset values. In this way, the energy loss of the system can be reduced, and the body height adjustment performance can be improved. Due to the implementation of the control strategy of the system, the processes of gas filling, gas release and pressure rising cannot be performed simultaneously, and thus the loss of gas is also reduced.
