摘要： A damper system includes an electromagnetic damper 10 including: (i) an electromagnetic motor 46 which operates in association with motions of a sprung portion and an unsprung portion toward and away from each other; and (ii) an external circuit 90 which includes (A) a first connection passage CFEB in which an electric current is allowed to only flow from a first terminal 100 as one of two terminals of the motor 46 to a second terminal 102 as the other of the two terminals and (B) a second connection passage DFEA in which the electric current is allowed to only flow from the second terminal 102 to the first terminal 100. The electromagnetic damper 10 is configured to generate a damping force that depends on an electromotive force of the electromagnetic motor 46, with respect to the motion of the sprung portion and the unsprung portion toward each other by permitting a generated current by the motor 46 to flow through the first connection passage CFEB and with respect to the motion of the sprung portion and the unsprung portion away from each other by permitting the generated current of the motor 46 to flow through the second connection passage DFEA. According to the present damper system, damping characteristic with respect to the motion of the sprung portion and the unsprung portion toward each other and damping characteristic with respect to the motion of the sprung portion and the unsprung portion away from each other can be easily made different from each other.

Further, it is possible to control also a propulsive force to be generated by the electromagnetic damper. Accordingly, the present damper system has an excellent vibration damping characteristic.

摘要： The magnitude of a linear damping coefficient C s is set so as to decrease the greater a maximum amplitude value α of an intermediate frequency sprung acceleration is. In the case where a damping force control apparatus carries out control for dampening vibrations of a sprung member using a nonlinear H-infinity control theory, the linear damping coefficient C s is set to a high value when the maximum amplitude value α of the intermediate frequency sprung acceleration inputted to a suspension apparatus is low. Accordingly, a requested damping force F req also increases, which makes it possible to quickly dampen vibrations in the sprung member. Meanwhile, in the case where the maximum amplitude value α of the intermediate frequency sprung acceleration is high, the linear damping coefficient C s is set to a low value. Accordingly, the requested damping force F req also decreases, which makes it possible to suppress degradation in the riding quality when intermediate frequency vibrations are inputted, and particularly makes it possible to suppress riding quality degradation when the vibration speed is high.
摘要翻译：线性阻尼系数Cs的大小被设定为减小中频簧上加速度的最大振幅值α越大。在衰减力控制装置使用非线性H-无穷大控制理论对簧上部件的衰减振动进行控制的情况下，当中频的最大振幅值α弹出时，线性衰减系数Cs被设定为高值输入到悬架装置的加速度低。因此，要求衰减力Freq也增大，能够迅速抑制簧上部件的振动。同时，在中频簧上加速度的最大幅值α高的情况下，线性阻尼系数Cs被设置为低值。因此，所要求的阻尼力Freq也减小，这使得可以在输入中频振动时抑制乘坐舒适度的降低，并且特别地可以在振动速度高时抑制乘坐舒适性劣化。
