To make it possible to reduce influences of gravitational acceleration from a vertical acceleration calculated value of a vehicle body by considering gradient of a road surface in the direction orthogonal to a straight advance direction of a vehicle.SOLUTION: A controller 9 as a control device is provided with a vertical acceleration correction-computing unit 9A and an attenuation force command computing unit 9B. The vertical acceleration correction-computing unit 9A has: straight advance direction gradient calculation means (a longitudinal slope calculation unit 15) for obtaining a road surface gradient degree (a longitudinal slope θ) in a straight advance direction of a vehicle; and orthogonal direction gradient calculation means (a bank gradient calculation unit 17) for obtaining a road surface gradient degree (a transverse slope φ) in the direction orthogonal to the straight advance direction of the vehicle. With respect to a vertical acceleration sensor value αzsens by a sprung acceleration sensor 8, corrected sprung vertical acceleration (a corrected vertical acceleration αzco) obtained by correcting the vertical acceleration sensor value αzsens by the longitudinal slope θ and the transverse slope φ is obtained.SELECTED DRAWING: Figure 3

    【課題】 車両の直進方向と直交する方向での路面の勾配を考慮し、車体の上下加速度算出値から重力加速度の影響を減らすことができるようにする。【解決手段】 制御装置としてのコントローラ9が、上下加速度補正演算部9Aと減衰力指令演算部9Bとを備えている。上下加速度補正演算部9Aは、車両の直進方向の路面傾斜度合い(縦断勾配θ)を求める直進方向勾配算出手段(縦断勾配算出部15)と、車両の直進方向と直交する方向の路面傾斜度合い(横断勾配φ)を求める直交方向勾配算出手段(バンク勾配算出部17)とを有し、ばね上加速度センサ8による上下加速度センサ値αzsensに対し、前記縦断勾配θと横断勾配φとにより、上下加速度センサ値αzsensを補正した補正ばね上上下加速度(補正後上下加速度αzco)を求める構成としている。【選択図】 図3
