摘要： The magnitude of a linear damping coefficient Cs 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 Cs 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 Freq 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 Cs is set to a low value. Accordingly, the requested damping force Freq 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的大小被设定为使中频弹簧加速度的最大振幅值α越大。在阻尼力控制装置使用非线性H无穷大控制理论进行用于抑制簧上部件的振动的控制的情况下，当中间频率的最大振幅值α弹簧时，将线性阻尼系数Cs设定为高值输入到悬架装置的加速度低。因此，所需的阻尼力Freq也增加，这使得可以快速地抑制簧上构件中的振动。同时，在中频弹簧加速度的最大振幅值α为高的情况下，将线性阻尼系数Cs设定为低值。因此，所要求的阻尼力Freq也减小，这使得可以抑制输入中频振动时的乘坐质量的劣化，特别是可以在振动速度高时抑制骑乘质量下降。

摘要： A suspension ECU 13 calculates a target characteristic changing coefficient a_new for changing a target characteristic, which is represented by a quadratic function, by use of the maximum actual roll angle Φ_max generated in a vehicle body during the current turning state and a turning pitch angle Θ_fy_max which is a fraction of an actual pitch angle Θ generated as a result of turning, and changes the target characteristic by use of the coefficient a_new. Subsequently, the suspension ECU 13 calculates the difference ΔΘ between the actual pitch angle Θ and a target pitch angle Θh corresponding to the actual roll angle Φ on the basis of the changed target characteristic, and calculates a total demanded damping force F to be cooperatively generated by the shock absorbers so as to reduce the difference ΔΘ to zero. Furthermore, in proportion to the magnitude of a lateral acceleration Gl, the suspension ECU 13 distributes the total demanded damping force F into a demanded damping force Fi on the turning-locus inner side and a demanded damping force Fo on the turning-locus outer side.

摘要： A damping force control apparatus for a vehicle computes an actual roll angle Φ and an actual pitch angle θ in step S11, and computes a difference Δθ between a target pitch angle θa and the actual pitch angle θ in step S12. In step 13, the apparatus computes a total demanded damping force F which must be cooperatively generated by shock absorbers so as to decrease the computed Δθ to zero. In step S14, the apparatus distributes the total demanded damping force F in proportion to the magnitude of a lateral acceleration G such that a demanded damping force Fi on the turn-locus inner side becomes greater than a demanded damping force Fo on the turn-locus outer side. In step S15, the apparatus controls the damping force of each of the shock absorbers to the damping force Fi or the damping force Fo. Thus, throughout a turn, a posture changing behavior in which the turn-locus inner side serves as a fulcrum can be maintained.

摘要： A corrected state space model obtained by correcting a state space model to represent a controllable system by adding an error matrix Δ to a state space model representing an uncontrollable system is designed. A control object is controlled based on a control input of the system represented by this corrected state space model. The control input is calculated by a state feedback controller. By correcting the state space model representing the uncontrollable system by the error matrix Δ, the system can be made controllable. Since the error matrix Δ is added to a state matrix, an influence of an error on an output of the system can be reduced.

摘要： Disclosed is a damping force control device for a vehicle that controls the damping coefficient of a damping force generation device on the basis of a final target control amount that is based on the target control amount for attitude control, which suppresses changes in the vehicle body attitude in at least the rolling direction, and the target control amount for riding comfort control, which increases riding comfort with regards to vehicle body vibrations in at least the rolling direction. The target control amount for riding comfort control is a control amount calculated as the total of a fixed basic control amount and a variable control amount. The target control amount and the variable control amount for attitude control are calculated, a post-correction basic control amount, which is nearer to the target control amount for attitude control than the basic control amount, is calculated, and the total of the post-correction basic control amount and the variable control amount is set as the final target control amount, thereby excellently achieving both the suppression of attitude changes and an increase in riding comfort.
