    • This invention relates to hydraulic suspension systems and in particular to vehicle oleopneumatic suspension systems employing sliding pillar struts. There is provided a suspension system (15) for a vehicle comprising a plurality of suspension struts (20), each mounted between a vehicle body (10) and a wheel assembly, each comprising: a cylinder (21) having a closed end and an inner bore (22); a piston rod (25) slideable within the inner bore (22) having a proximal end which terminates within the inner bore (22) and a distal end which extends from the inner bore (22). Between the inner bore (22) and the piston rod (25) there is mounted an oil seal (34) which seals a strut volume (59). A hydrostatic bearing (30) is mounted within and vents into the strut volume (59). A hydraulic circuit and associated control system is adapted to control flow of hydraulic fluid between the strut volume (59) and a reservoir (72), thereby providing control of at least the time-averaged axial position of the piston rod (25) relative to its corresponding inner bore (22).

    • A stabilizer system for a vehicle which includes a stabilizer bar and an actuator and which executes a control (S1, S4)of actively changing stiffness of the stabilizer bar in accordance with roll moment acting on a body of the vehicle. In the stabilizer system, each of a situation in which the vehicle is running straightforward and a situation in which a torque generating direction of a motor of the actuator changes in opposite direction plural times is identified as a specific situation (S2). In the specific situation, there are executed, for instance, a control (S7) of changing an operation mode of the motor such that presence or absence of occurrence of resistance of the actuator against its operation by external input force is changeable, and a control (S6) of limiting a supply current to the motor such that the torque generating direction of the motor is inhibited from coinciding with a direction away from a neutral position. Owing to such controls, the ease of the operation of the actuator can be made different depending upon the operational direction, thereby improving the stability and the ride comfort of the vehicle.
    • 一种用于车辆的稳定器系统,其包括稳定杆和致动器,并且执行根据作用在车身上的滚动力矩主动地改变稳定杆的刚度的控制(S1,S4)。 在稳定器系统中,识别出车辆直线运转的情况和致动器的电动机的转矩产生方向相反方向多次的情况,作为具体情况(S2)。 在具体情况下,例如执行改变电动机的操作模式的控制(S7),使得执行器的电阻的出现与否由外部输入力的操作而变化,并且控制 (S6)限制向电动机的供给电流,使得电动机的转矩产生方向被禁止与远离中立位置的方向一致。 由于这样的控制,可以根据操作方向使致动器的操作容易化,从而提高车辆的稳定性和乘坐舒适性。
