特徴とするピツチング制御装置。 A hydraulic suspension unit is installed between a wheel side member and a vehicle body side member of a vehicle and is provided for each wheel and has a fluid chamber, and the damping force provided for each suspension unit is switched between large and small. A damping force switching device, a vehicle height detection means for detecting a vehicle height, a cycle detection means for detecting a cycle between normal vehicle heights detected by the vehicle height detection means, and a cycle detected by the cycle detection means. fluid pressure control means for raising or lowering the front and rear vehicle heights of the suspension unit to keep the vehicle body horizontal when the vehicle body is within a predetermined range; and acceleration detection means for detecting longitudinal acceleration acting on the vehicle body. , a damping device that operates the damping force switching device to increase the damping force of each of the suspension units when the acceleration detected by the acceleration detection device is equal to or higher than a set value when the fluid pressure control device performs control; A pitching control device comprising a force control means.
