摘要： An air chamber (53) of a damping force adjusting mechanism (49) disposed in a hydraulic shock absorber (3) of a damping force adjusting type communicates with an air chamber (7) of an air spring through a tubular path (57). A free piston (51) is transferred in accordance with the pressure of the air chamber and a spool (46) is transferred to shift a damping force. The damping force presents a soft characteristic both on the extending side and on the retracting side in a usual status, presents a hard characteristic on the extending side and a soft characteristic on the retracting side when the pressure of the air chamber is high, and presents a soft characteristic on the extending side and a hard characteristic on the retracting side when the pressure of the air chamber (7) is low. The damping force can be obtained, which approximates the damping force control on the basis of a so-called sky-hook theory. Therefore, the air suspension apparatus can alleviate the input from the axle side and improve a riding comfort and stability in operability by controlling the vibration on the vehicle body side.

摘要： The flow of a hydraulic fluid caused by sliding movement of a piston is controlled through a sub-disk valve, a main disk valve and a disk valve to generate damping force. A coil is energized to urge a plunger in the valve closing direction against spring force from a spring, thereby adjusting the relief pressure of the disk valve and thus controlling the damping force. The pressure in a back-pressure chamber varies according to the relief pressure of the disk valve. Thus, the valve opening pressure of the main disk valve is also adjusted. An abrupt input is absorbed by relieving the pressure from the back-pressure chamber by deflection of the disk valve. Because “soft” damping force characteristics, which are often used, are maintained with a small electric current, the power consumption can be reduced. When there is a failure, the spring causes the small-diameter portion of the plunger to close ports, thereby switching the damping force to “hard” side and thus ensuring the steering stability.
摘要翻译：由活塞的滑动运动引起的液压流体的流动通过副盘阀，主盘阀和盘阀来控制，以产生阻尼力。线圈被通电以抵抗来自弹簧的弹簧力在阀关闭方向上推动柱塞，从而调节盘阀的释放压力，从而控制阻尼力。背压室中的压力根据盘阀的溢流压力而变化。因此，主盘阀的开阀压力也被调整。通过盘阀的偏转减轻来自背压室的压力来吸收突然的输入。由于经常使用的“软”阻尼力特性以小电流保持，所以能够降低功耗。当发生故障时，弹簧使柱塞的小直径部分关闭端口，从而将阻尼力切换到“硬”侧，从而确保操纵稳定性。

摘要： The present invention provides a suspension control apparatus which can perform good suspension control regardless of change in temperature. The suspension control apparatus comprises a transistor capable of being turned ON/OFF in response to a level of a PWM signal, a current sensor for detecting current flowing through a proportional solenoid, and a controller for adjusting a duty ratio of the PWM signal on the basis of the comparison between a current data detected by the current detecting means and a previously set reference data to correct command current. The current actually flowing through the proportional solenoid is measured, and the duty ratio of the PWM signal is adjusted to obtain a desired damping force on the basis of the measured current. With this arrangement, if a temperature of the proportional solenoid is increased to increase resistance thereof due to application of current to the proportional solenoid, the applied current is corrected to provide the desired damping force.

摘要： By passing the vertical acceleration through a phase adjusting filter and a gain adjusting filter, the phase of the vertical acceleration is advanced by 49 degrees so that the phase difference with respect to the actual relative velocity becomes 180 degrees in the neighborhood of the vehicle body resonance point, thereby making the phase of the vertical acceleration, in effect, coincident with the phase of the relative velocity. In the neighborhood of the vehicle body resonance point (1 Hz), the gain of the estimated relative velocity takes a small value. In frequency regions other than the neighborhood of the vehicle body resonance point, the gain of the estimated relative velocity is increased. Consequently, the controlled variable in the neighborhood of the vehicle body resonance point increases, and the controlled variable in higher frequency regions decreases. Damping force is adjusted in correspondence to the controlled variable. Thus, it is possible to improve ride quality in the neighborhood of the vehicle body resonance point (1 Hz).
摘要翻译：通过使垂直加速度通过相位调整滤波器和增益调整滤波器，垂直加速度的相位提前49度，使得相对于实际相对速度的相位差在车身谐振附近变为180度点，从而使垂直加速度的相位实际上与相对速度的相位一致。在车体共振点（1Hz）附近，估计的相对速度的增益取小值。在车体共振点附近的频率区域中，估计的相对速度的增益增加。因此，车体共振点附近的受控变量增大，高频区域的受控变量减小。阻尼力相应于受控变量进行调整。因此，能够提高车体共振点附近的乘坐质量（1Hz）。

摘要： In the suspension control apparatus of the present invention, when a lateral acceleration differential value falls outside a lateral acceleration differential value range, a controller calculates a control input for an actuator, based on the lateral acceleration differential value, in preference to a lateral acceleration. Therefore, immediately after the start of rolling of a vehicle and just prior to the end of the rolling when the lateral acceleration differential value falls outside the lateral acceleration differential value range, the control input for the actuator is calculated based on the lateral acceleration differential value. By this arrangement, it is possible to suppress any uncomfortable sensation which is likely to be transmitted to an occupant of the vehicle immediately after the start of rolling and just prior to the end of rolling in a conventional technique, in which the control input for the actuator is calculated by adding the control input varying in proportion to the lateral acceleration and the control input varying in proportion to the lateral acceleration differential value.
摘要翻译：在本发明的悬架控制装置中，当横向加速度差分值落在横向加速度差异值范围之外时，控制器基于横向加速度微分值，优先于侧向加速度来计算执行机构的控制输入。因此，当横向加速度差分值落在横向加速度差值范围之外时，在车辆开始滚动之后并且刚好在滚动结束之前，基于横向加速度差分值来计算用于致动器的控制输入。通过这种布置，可以在常规技术中抑制可能在刚刚开始轧制之后刚好在轧制结束之前传递给车辆的乘客的任何不适感，其中，用于通过将与横向加速度成比例的控制输入和与横向加速度差值成比例变化的控制输入相加来计算执行器。

摘要： A first observer gain of an actual damping force estimating observer 21 calculates a dynamic characteristic compensating signal, and a second observer gain of an actual vehicle model state amount estimating observer 23 calculates a vehicle model compensating signal, from an output deviation corresponding to a difference between a sprung speed (observation output) provided from a vehicle 2 and an estimated sprung speed (estimated observation output) provided from a vehicle approximation model of the actual vehicle model state amount estimating observer 23. The dynamic characteristic compensating signal is input into a dynamic characteristic providing unit of the actual vehicle model state amount estimating observer 23, and is used for adjustment of the setting of the dynamic characteristic providing unit. Therefore, it is possible to curb time lag occurrence in a control, and thereby perform a vibration control with improved accuracy.

摘要： In a suspension control system a sky-hook command signal (B) obtained from velocity data obtained by integrating a sprung mass acceleration (αu) from a sprung mass acceleration sensor (9u) and an unsprung mass vibration damping command signal (C) obtained on the basis of an unsprung mass acceleration (αd) detected by an unsprung mass acceleration sensor (9d) are added together to obtain a control signal (A) for a damping characteristic inverting type shock absorber (6). The control signal (A) reflects the unsprung mass acceleration (αd) that leads in phase by 90° the piston speed. Accordingly, it is possible to compensate for a response delay due to an actuator (11), etc.

摘要： The piston 10 is constituted so as to rotate relative to the first cylinder 8 while moving relative to the first cylinder 8 in the axial direction when fluid is supplied to and discharged from the interior of the first cylinder 8, and the piston 16 is constituted to be incapable of rotation relative to the second cylinder 9, but capable of movement relative to the second cylinder 9 in the axial direction.
