摘要： A suspension control system is designed to adjust suspension characteristics between hard and soft for bounding and rebounding stroke independently of each other. The system has a sensor means for monitoring speed of a vehicular body as a sprung mass for producing a vehicle body speed indicative signal, which vehicle body speed indicative signal has a variable signal polarity depending upon the direction of vibration, and a sensor means for monitoring relative speed between the vehicular body and a vehicular wheel as an unsprung mass for producing a relative speed indicative signal which also has a variable signal polarity depending upon the direction of relative movement of the vehicular body and the vehicular wheel. A control unit detects a combination of signal polarities of the vehicle body speed indicative signal and the relative speed indicative signal for adjusting damping characteristics for bounding and rebounding vibration independently of each other and depending on the detected combination.

摘要： A suspension control system for an automotive vehicle is provided. This suspension control system comprises variable damping force shock absorbers and a control unit which controls the shock absorbers to assume damping force characteristics in a range between preselected higher and lower damping coefficients. The control unit is operable to provide a control parameter indicative of bouncing motion of a vehicle body based on sprung vertical speed to determine a damping coefficient against the bouncing motion. When the control parameter is greater than a threshold value, the damping coefficient is modified to a lower value, while when the control parameter is less than the threshold value, the damping coefficient is modified to a higher value. With this damping coefficient modification, the bouncing motion is suppressed effectively while assuring passenger comfort.

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.
