The invention discloses a damping-controllable external magneto-rheological intelligent suspension system, a control method and a vehicle. The damping-controllable external magneto-rheological intelligent suspension system comprises a suspension oil cylinder, a connecting pipe, a magneto-rheological control unit and an energy storage device. The magneto-rheological control unit is located between the suspension oil cylinder and the energy storage device, and the three are connected through a connecting pipe. Magnetorheological fluid is arranged among the suspension oil cylinder, the magnetorheological control unit and the energy accumulator; when the suspension oil cylinder is compressed and extended, the suspension oil cylinder and the energy storage device conduct magnetorheological fluid to flow back and forth together, and when impressed current is applied to the magnetorheological control unit, an electromagnetic field in the magnetorheological control unit promotes the magnetorheological fluid to be solidified, so that the flowing speed of the magnetorheological fluid and the damping of a suspension system are influenced; the electromagnetic field intensity is improved and reduced by increasing and reducing the impressed current, so that the system damping is adjusted. The environment adaptability, comfort and system reliability of the vehicle can be effectively improved, the operation efficiency of the vehicle is improved, meanwhile, the design and manufacturing process difficulty can be reduced, and the cost is reduced.

    本发明公开了可控阻尼的外部磁流变智能悬架系统、控制方法及车辆,包括悬挂油缸、连接管、磁流变控制单元和储能器;磁流变控制单元位于悬挂油缸和储能器之间,三者之间通过连接管进行连接;悬挂油缸、磁流变控制单元和储能器之间设有磁流变液;当悬挂油缸压缩和延伸时,与储能器一起传导磁流变液来回流动,对磁流变控制单元施加外加电流时,磁流变控制单元中的电磁场促使磁流变液发生“凝固”,从而影响磁流变液的流动速度和悬架系统阻尼的大小;通过增加和降低外加电流,从而提高和降低电磁场强度,以便调整系统阻尼。本发明可以有效提升车辆的环境适应性、舒适性和系统可靠性,提升车辆作业效率,同时可以降低设计和制造工艺难度,降低成本。
