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.

    本发明公开了一种基于磁流变油气弹簧的车辆减振控制系统及方法,包括磁流变油气悬架单元、采集单元以及控制单元;所述磁流变油气悬架单元包括磁流变油气弹簧以及PINCH模式磁流变阀;所述磁流变油气弹簧用于油气悬架中的液压互联,所述PINCH模式磁流变阀用于切换液压互联形式;所述采集单元用于采集车辆的运动姿态信息;所述控制单元用于根据车辆的运动姿态信息,调整油气悬架的互联形式,并对车辆运动姿态进行控制,使得车辆运行状态达到目标状态。本发明能够获得更好的抗侧倾刚度和抗俯仰刚度,提升了重载车辆的整体减振性能以及操纵稳定性。
