A vehicle includes a suspension system for providing configurable stiffness and damping. The system comprises: a plurality of hydraulic cylinders, each hydraulic cylinder corresponding to a respective wheel of the vehicle; and one or more valve assemblies for controlling hydraulic fluid in the plurality of hydraulic cylinders to achieve a plurality of suspension modes that affect bounce, pitch, roll, and warp. The system also includes a plurality of accumulators that act as spring elements to store and release the hydraulic fluid when the plurality of hydraulic cylinders are compressed and rebounded. The system includes control circuitry for controlling the valve assembly to achieve one or more suspension modes defining a bounce stiffness, a pitch stiffness, a roll stiffness, and a warp stiffness. By generating a control signal for the valve assembly, various interconnections or fluid paths corresponding to the suspension mode may be achieved. The hydraulic cylinder is dual acting, has a rebound volume and a compression volume, and may be coupled to a damping valve.

    车辆包括一种用于提供可配置刚度和阻尼的悬架系统。该系统包括:多个液压缸,每个液压缸对应于该车辆的相应车轮;和一个或多个阀组件,该一个或多个阀组件用于控制该多个液压缸中的液压流体以实现影响弹跳、俯仰、侧倾和翘曲的多个悬架模式。该系统还包括多个蓄能器,该多个蓄能器用作弹簧元件,以在该多个液压缸压缩和回弹时存储和释放该液压流体。该系统包括控制电路系统,该控制电路系统用于控制该阀组件,以实现限定弹跳刚度、俯仰刚度、侧倾刚度和翘曲刚度的一个或多个悬架模式。通过针对该阀组件生成控制信号,可实现对应于该悬架模式的各种互连或流体路径。该液压缸是双作用的,具有回弹体积和压缩体积,并且可联接到阻尼阀。
