The invention discloses a vehicle vibration reduction control system and method based on a magneto-rheological hydro-pneumatic spring. The vehicle vibration reduction control system comprises a magneto-rheological hydro-pneumatic suspension unit, an acquisition unit and a control unit. The magneto-rheological hydro-pneumatic suspension unit comprises a magneto-rheological hydro-pneumatic spring and a PINCH mode magneto-rheological valve; the magneto-rheological hydro-pneumatic spring is used for hydraulic interconnection in a hydro-pneumatic suspension, and the PINCH mode magneto-rheological valve is used for switching a hydraulic interconnection mode; the acquisition unit is used for acquiring moving posture information of a vehicle; and the control unit is used for adjusting the interconnection form of the hydro-pneumatic suspension according to the moving posture information of the vehicle and controlling the moving posture of the vehicle, so that the running state of the vehicle reaches a target state. According to the invention, better anti-roll rigidity and anti-pitch rigidity can be obtained, and the overall vibration reduction performance and the handling stability of the heavy-duty vehicle are improved.
