To provide a vehicle active suspension device that facilitates adjustment of attenuation force of an attenuation force variable damper with respect to rotational behavior of a vehicle, can suppress adjustment cost and adjust the same with high completeness, and suppressing production cost.SOLUTION: A vehicle active suspension device has a roll suppression control portion 26 that computes a sprung roll angle and unsprung roll angle from a sprung vertical behavior of a vehicle detected by acceleration sensors 15, 16, and 17, and computes a roll attenuation force control value on the basis of a difference between the sprung roll angle and the unsprung roll angle, and a pitch suppression control portion 27 that computes a sprung pitch angle and an unsprung pitch angle from the sprung vertical behavior, and computes a pitch attenuation force control value on the basis of a difference between the sprung pitch angle and the unsprung pitch angle. On the basis of the roll attenuation force control value and the pitch attenuation force control value, attenuation force of a plurality of attenuation variable dampers 12a to 12d is controlled.SELECTED DRAWING: Figure 2

    【課題】車両の回転挙動に対する減衰力可変ダンパの減衰力の調整を容易とし、調整コストを抑えるとともに完成度高く調整することが可能で、かつ生産コストを抑えた車両のアクティブサスペンション装置を提供する。【解決手段】加速度センサ15、16、17によって検出した車両のばね上の上下挙動からばね上のロール角及びばね下のロール角を演算し、ばね上のロール角とばね下のロール角との差に基づいてロール減衰力制御値を演算するロール抑制制御部26と、ばね上の上下挙動からばね上のピッチ角及びばね下のピッチ角を演算し、ばね上のピッチ角とばね下のピッチ角との差に基づいてピッチ減衰力制御値を演算するピッチ抑制制御部27と、を有し、ロール減衰力制御値及びピッチ減衰力制御値に基づいて複数の減衰力可変ダンパ12a~12dの減衰力を制御する。【選択図】図2
