摘要：
An automotive suspension system includes means for monitoring bounding and rebounding strokes for producing a stroke indicative signal, and means for detecting frequency of bounding and rebounding strokes based on the stroke indicative signal. The suspension characteristics are hardened when the detected frequency is lower than a predetermined stroke frequency threshold for providing higher driving stability. On the other hand, when the detected stroke frequency is higher than or equal to the stroke frequency threshold, the suspension characteristics are switched between harder suspension characteristics and softer suspension characteristics depending upon stroke position for absorbing vibration energy and assuring riding comfort.
