The invention relates to the technical field of automobiles, in particular to a double-valve control type full-active automobile suspension system which comprises a shock absorber assembly, a hydraulic pump assembly, a compression electromagnetic valve and a recovery electromagnetic valve. The shock absorber assembly comprises a middle cylinder, a working cylinder and an oil storage cylinder, and an inner cavity of the working cylinder is a working cavity; a piston rod dividing the working cavity into an upper working cavity and a lower working cavity is arranged in the working cavity, the working cylinder is sleeved with the middle cylinder, a middle cavity is formed between the working cylinder and the middle cylinder, the middle cavity is communicated with the upper working cavity, the middle cylinder is sleeved with the oil storage cylinder, and an oil storage cavity is formed between the oil storage cylinder and the middle cylinder. An inlet and an outlet of the restoring electromagnetic valve are respectively communicated with the middle cavity and the oil storage cavity, the compression electromagnetic valve is fixed on the oil storage cylinder, and an inlet and an outlet of the compression electromagnetic valve are respectively communicated with the working lower cavity and the oil storage cavity. And a first oil port and a second oil port of the hydraulic pump assembly are respectively communicated with the middle cavity and the working lower cavity. The passive damping adjusting mode and the full-active damping adjusting mode are both considered, and the posture of the automobile body can be actively adjusted.
