摘要： The present invention provides a suspension control apparatus including dither amplitude setting device which is adapted to set the amplitude of the dithering current to be superimposed on the command current is set to a small value in a region in which a damping force generated by the shock absorber changes at a high rate relative to changes in intensity of the current applied to the solenoid. The present invention also provides a suspension control apparatus including dither frequency setting device which is adapted to set the frequency of the dithering current to a high frequency in a region in which a damping force generated by the shock absorber changes at a high rate relative to changes in intensity of the current applied to the solenoid and set the frequency of the dithering current to a low frequency in a region other than the above-mentioned region. The suspension control apparatus of the present invention prevents generation of undesirable noise and vibration while suppressing an increase in hysteresis with respect to a damping force.
摘要翻译：本发明提供了一种悬架控制装置，其包括抖动幅度设定装置，其适用于将由所述减震器产生的阻尼力产生的阻尼力的所述指令电流中叠加的抖动电流的振幅设定为小值相对于施加到螺线管的电流的强度的变化，高速率的变化。本发明还提供了一种悬架控制装置，其包括抖动频率设定装置，其适于将抖动电流产生的阻尼力相对于变化的高速度变化的区域中的抖动电流的频率设定为高频施加到螺线管的电流的强度，并且将抖动电流的频率设定在除了上述区域以外的区域中的低频。本发明的悬架控制装置防止了相对于阻尼力的滞后增加而产生不期望的噪声和振动。

摘要： A suspension control system for a vehicle includes a plurality of hydraulic cylinders interposed between the vehicle body and the respective axles of front right, front left, rear right and rear left wheels for controlling the vehicle height by the action of a hydraulic fluid charged into and discharged from the cylinders. A plurality of normally-closed charge-discharge valves are provided to correspond to respective of the hydraulic cylinders. When the hydraulic fluid is to be charged into or discharged from the hydraulic cylinders, among the charge-discharge valves, at least the left and right charge-discharge valves associated with either the front right and front left wheels or the rear right and rear left wheels are not opened simultaneously, but either of the left and right charge-discharge valves is selectively opened.
摘要翻译：一种用于车辆的悬架控制系统包括多个液压缸，其插入在车体与前右，前左，后右后轮和左后轮之间的相应轴之间，用于通过液压流体的作用控制车辆高度，从气瓶排出。多个常闭的充放电阀被设置成对应于各个液压缸。当液压油被充入液压缸或从液压缸排出时，在充气 - 排气阀中，至少与右前左前轮左后左右相关联的左，右充气 - 排气阀车轮不能同时打开，而是选择性地打开左右充气 - 排气阀。
