摘要： When a road surface is judged to be undulating and rough, a parameter for a bad road to attain “soft” damping force characteristics is set with priority to setting of a parameter for an undulating road to attain “hard” damping force characteristics. Consequently, “soft” damping force characteristics are obtained to improve the ride quality. This order of the priority is adopted especially when a vehicle speed is low. When the vehicle speed is high, the order of the priority is reversed.

摘要： The present invention provides a suspension control apparatus capable of an excellent vibration control by a model thereof designed to incorporate nonlinearity and a time-lag element of a control damper. The present invention employs the backstepping method which is one of nonlinear control methods, and is designed so as to incorporate the nonlinearity of a damper 4. In addition, a nonlinear controller 5 uses a damping force Fu obtained by expressing the dynamics of a damping force characteristic variable portion [damping force Fu(v, i)] by a first-order lag system, so as to compensate the dynamics of the damper 4, whereby a control system is formed so as to incorporate the time-lag element of the control damper. As a result, it is possible to reduce time lag, and to practically adjust a control force according to the characteristics of the control damper.

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： A suspension control apparatus includes a variable damping coefficient type shock absorber disposed between sprung mass and unsprung mass of a vehicle and an actuator for setting and adjusting a damping coefficient of the variable damping coefficient type shock absorber on the basis of a control signal. An upward and downward absolute velocity detector for detecting an upward absolute velocity and a downward absolute velocity of the vehicle is provided. A control unit changes a signal from the upward and downward absolute velocity detector in accordance with a running condition of the vehicle to obtain a control target signal. A control signal generator outputs the control signal for the actuator on the basis of the control target signal from the control unit. A signal representative of the roughness of a road surface on which the vehicle is running is generated and a feature of the control unit is adjusted for changing the control signal on the basis of the signal representative of the road surface roughness.
