ヨン制御装置。[Scope of Claim for Utility Model Registration] A vehicle height adjustment mechanism that is provided between the sprung portion of a vehicle and the unsprung portion of each wheel, and adjusts the height of each vehicle according to the control of pressure supplied from a pressure source. An active suspension control device comprising: a relative displacement detection means for detecting relative displacement between the sprung mass of the vehicle and the unsprung mass of each wheel; and at least one of lateral acceleration or longitudinal acceleration generated in the vehicle. acceleration detection means for detecting; control pressure value calculation means for calculating a control pressure value component using a predetermined gain according to each detection value of both of the detection means; and a sum of the control pressure value components calculated by the pressure source control pressure value recalculation means for calculating a control pressure value component with a lower priority among the control pressure value components using a limit gain smaller than the predetermined gain so that the pressure is smaller than the pressure of the control pressure value component; Features an active suspension control device.
