摘要： In order to ensure riding comfort and driving stability in an automotive suspension system, the nature of the effect of the damping force generated by the suspension system is observed. When the damping characteristics of the suspension system are too hard, resulting in amplification of vibrations in the suspension system, the damping characteristics are softened to ensure satisfactory riding comfort. Therefore, according to the present invention, an automotive suspension system has variable damping characteristics which depend on the nature of the damping force produced in response to bounding and/or rebounding motion of the vehicle so as to optimize damping characteristics to achieve both riding comfort and driving stability. In the preferred embodiment, a suspension control system uses the vibration frequency of a sprung mass and the relative speed between the sprung mass and an unsprung mass as control parameters representing the nature of damping force.

摘要： A seat suspension is provided that has a damper unit which is connected between the seat and the chassis on which the seat is mounted. The damper can be switched between soft and hard settings. The damper switching is controlled based on the relative position of the seat and one of the relative or absolute velocity of the seat. When the seat and the chassis are moving in the same direction the damper is set to soft, (producing a low damping effect), while when the seat and chassis are moving in opposite directions the damper is switched to hard (producing a high damping effect).

摘要： A suspension control system for an automotive vehicle automatically adjusts the damping strength of variable shock absorbers or other dampers in accordance with road surface conditions as recognized by frequency analysis of a vehicle height or vibration sensor signal. The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels or unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands and the amplitude of each is compared to a corresponding reference level to give an indication of the irregularities in the road surface. Specifically, a high-amplitude low-frequency component indicates large-scale bumps and dips capable of bouncing the vehicle whereas a strong high-frequency component reflects a rough-textured road surface, such as gravel. The comparison information is sent to a suspension system controller which causes actuation of the shock absorbers to a hard mode of operation when the low-frequency sensor signal components are relatively strong.
摘要翻译： 用于机动车辆的悬架控制系统根据车辆高度或振动传感器信号的频率分析识别的路面条件自动调节可变减震器或其它阻尼器的阻尼强度。 传感器信号反映车身从路面的垂直位移，并且包括仅由于车轮或簧下质量相对于路面的位移而产生的高频分量，以及由于车身或弹簧质量的位移引起的低频分量 。 传感器信号被过滤到这些单独的频带中，并且将每个频带的振幅与相应的参考电平进行比较，以给出路面中的不规则性的指示。 具体地说，高振幅低频分量表示能够使车辆反弹的大规模的颠簸和倾斜，而强的高频分量反映了诸如砾石的粗糙纹理的路面。 比较信息被发送到悬架系统控制器，当低频传感器信号分量相对较强时，该系统控制器使得减震器致动到硬操作模式。
