The invention discloses an active hydro-pneumatic suspension system, and relates to the field of vehicle suspension systems, and the active hydro-pneumatic suspension system comprises a hydraulic cylinder with two sealed ends; openings are formed in the side walls of the hydraulic cylinders; a compression valve and a rebound valve are arranged at one end of the piston rod; the compression valve and the rebound valve divide the hydraulic cylinder into a rod cavity and a rodless cavity according to the movement direction of the piston rod; the other end of the piston rod extends out of the hydraulic cylinder; the energy accumulator is communicated with the rodless cavity and the rod cavity through the one-way throttle valve; oil circularly flows among the energy accumulator, the rodless cavity and the rod cavity; the motor is connected with the hydraulic pump; the hydraulic pump is respectively communicated with the rod cavity and the rodless cavity; the motor drives the hydraulic pump; the controller assembly is connected with the motor, the first one-way throttle valve and the second one-way throttle valve. And the controller assembly is used for adjusting the opening degrees of the first one-way throttle valve and the second one-way throttle valve and the rotating speed of the motor. The driving smoothness of the vehicle is improved, and energy consumption is reduced.
