The invention relates to a vehicle suspension control device and a vehicle suspension control method, which can effectively reduce vibration of a sprung structure. This vehicle suspension control device is provided with: an actuator that causes a control force in the vertical direction to act between an unsprung structure and a sprung structure; and an electronic control unit that controls the actuator so as to generate a control force corresponding to a requested control amount requested in order to reduce vibration of the sprung structure. The requested control amount includes at least two control terms among a displacement term, a speed term, and an acceleration term related to the displacement, the speed, and the acceleration of the sprung structure. The electronic control unit executes: a calculation process for calculating the magnitude of each frequency component of a plurality of frequency bands included in the road surface vibration information; and a gain determination process for determining the control gain of each of the at least two control terms so as to vary on the basis of the magnitude of the frequency component of each of the plurality of frequency bands.
本发明涉及车辆用悬架控制装置以及车辆用悬架控制方法,可有效地进行簧上构造体的减振。车辆用悬架控制装置具备:促动器,使上下方向的控制力作用于簧下构造体与簧上构造体之间;和电子控制单元,控制促动器以便产生与为了降低簧上构造体的振动而被请求的请求控制量相应的控制力。请求控制量包括与簧上构造体的位移、速度以及加速度相关的位移项、速度项以及加速度项中的至少2个控制项。电子控制单元执行:计算处理,计算路面振动信息所包括的多个频带各自的频率成分的大小;和增益决定处理,以基于多个频带各自的频率成分的大小而变化的方式决定至少2个控制项各自的控制增益。
