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 shock absorber has a cylinder tube coaxially arranged with a strut tube for defining therebetween an annular reservoir chamber and an upper reservoir chamber which is separated from the annular reservoir chamber. A first fluid path is defined for permitting fluid flow from a lower fluid chamber in the cylinder tube to an upper fluid chamber and the annular reservoir chamber in response to bounding stroke of vibration. A second fluid path is also defined for permitting fluid flow from the lower fluid chamber and the annular reservoir chamber to the upper fluid chamber and the upper reservoir chamber, in response to rebounding stroke of vibration. A first flow restriction means is disposed in the first path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics. A second flow restriction means is also disposed in the second path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics.

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.
