Abstract:
A vehicle suspension control device includes: an actuator configured to apply a control force in a vertical direction between an unsprung structure and a sprung structure; and an electronic control unit configured to control the actuator so as to generate the control force according to a required control amount for reducing vibration of the sprung structure. The required control amount includes at least two control terms of a displacement term, a velocity term, and an acceleration term related to displacement, velocity, and acceleration of the sprung structure. The electronic control unit calculates a magnitude of a frequency component of each of a plurality of frequency bands included in road surface vibration information, and determines a control gain of each of the at least two control terms so as to change based on the magnitude of the frequency component of each of the plurality of frequency bands.
