摘要： A system and method for controlling a damper of vehicular suspension in which when the vehicle runs on a paved road and a frequency at which the detected sprung mass acceleration exceeds a dead zone is below a set value, the damping force characteristic is optimally controlled in a predetermined variable range. When the vehicle runs on a rough road and a frequency at which the detected acceleration exceeds the dead zone is above the set value, a minimum damping force limit of the predetermined variable range of the damping force characteristic is shifted toward a relatively high damping force side, The dead zone is set with an average value of the acceleration of sprung mass as a center. Hence, when the vehicle turns and zigzags, the vehicular body is inclined so that an absolute value of the sprung mass acceleration is largely changed. In this case, when an average value of the acceleration of the sprung mass is accordingly changed and the dead zone is accordingly shifted. Thus, the frequency at which the sprung mass acceleration exceeds the dead zone accurately corresponds to a situation on a road surface and the damping force characteristic is accurately controlled according to the road surface condition.
摘要翻译：一种用于控制车辆悬架的阻尼器的系统和方法，其中当车辆在铺路面上行驶时，检测到的悬挂质量加速度超过死区时的频率低于设定值，阻尼力特性被最佳地控制在预定可变范围。当车辆在粗糙的道路上行驶，并且检测到的加速度超过死区的频率高于设定值时，阻尼力特性的预定可变范围的最小阻尼力极限向相对较高的阻尼力侧移动死区以弹簧质量加速度的平均值为中心设定。因此，当车辆转弯和锯齿形时，车身倾斜，从而使悬挂质量加速度的绝对值发生很大变化。在这种情况下，当相应地改变弹簧质量的加速度的平均值并且死区相应地移动时。因此，弹簧质量加速度超过死区的频率准确地对应于路面上的情况，并且根据路面状况来精确地控制阻尼力特性。

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.

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.

In the shock absorber, a flow of damping fluid induces a load on an actuator of the shock absorber during bouncing and rebouncing of the shock absorber, and the actuator is actuated in response to an output signal of a control unit. In order for the actuator to counteract the load applied thereto, the output signal is modified in response to the load.
