The invention relates to the technical field of vehicle suspension systems, in particular to an intelligent hydraulic four-wheel interconnected active suspension system, a control method and a vehicle. The invention provides an intelligent hydraulic four-wheel interconnected active suspension system which comprises a plurality of hydraulic branches, a plurality of wheel end hydraulic cylinders capable of being connected with spiral springs in parallel, a set of control valve bank, a plurality of communicating pipelines, a plurality of energy accumulators, a plurality of rigidity adjusters, a plurality of damping adjusters and an energy supply unit. According to the invention, not only can vehicle body lifting, multi-rigidity modes, damping stepless adjustment, four-wheel leveling, ramp driving posture adjustment and crossed shaft and rugged road surface driving adjustment be realized, but also heeling, pitching and vertical bumping of the vehicle body can be self-adaptively inhibited in each rigidity mode; the device is simple in structure and good in driving working condition adaptability, so that the vehicle is more suitable for multi-working-condition driving including cross-country.

    本发明涉及车辆悬架系统技术领域,具体涉及一种智能液压四轮互联主动悬架系统和控制方法、车辆。本发明提供的智能液压四轮互联主动悬架系统,包括多条液压支路、多个可与螺簧并联的轮端液压缸、一套控制阀组、若干连通管路、若干个蓄能器、若干个刚度调节器和阻尼调节器及供能单元。本发明不仅能实现车体升降、多刚度模式、阻尼无级可调、四轮调平、坡道行驶姿态调节、交叉轴和崎岖路面行驶调节,而且在每种刚度模式下能够自适应地抑制车身的侧倾、俯仰和垂向颠簸;本发明结构简单,行驶工况适应性好,使车辆更适合于包含越野的多工况行驶。
