To provide a vehicle body attitude control device which can perform proper pitch control even when roll control is executed.SOLUTION: A controller 21 controls the attitude of a vehicle body by controlling the generation force of attenuation force variable dampers 6, 9 provided between front wheels 2, rear wheels 3 and a vehicle body 1 of a vehicle. The controller 21 comprises: target attenuation force calculation units 25, 26 which calculate a roll command value for controlling the roll state of a vehicle body 1 from the road surface state; a pitch moment prediction unit 52 which predicts a pitch moment generated in the vehicle body 1 on the basis of the roll command value; an absolute value calculation unit 29 and a target pitch moment calculation unit 30 which calculate a target pitch moment such that a degree of diving of the vehicle body 1 increases according to the magnitude of a roll rate of the vehicle body 1; and a pitch rate correction unit 53 which corrects the calculation value by the target pitch moment calculation unit 30 in consideration of the prediction value by the pitch moment prediction unit 52.SELECTED DRAWING: Figure 2

    【課題】 ロール制御を実行しているときでも、適切なピッチ制御が可能な車体姿勢制御装置を提供する。【解決手段】 コントローラ21は、車両の前輪2、後輪3と車体1の間に設けられる減衰力可変ダンパ6,9の発生力を制御することにより、車体の姿勢を制御する。コントローラ21は、路面状態から車体1のロール状態を制御するためのロール指令値を算出する目標減衰力演算部25,26と、ロール指令値に基づいて車体1に発生するピッチモーメントを予測するピッチモーメント予測部52と、車体1のロールレイトの大きさに応じて車体1がダイブする度合いが増大するように目標ピッチモーメントを算出する絶対値演算部29および目標ピッチモーメント算出部30と、ピッチモーメント予測部52による予測値を考慮して、目標ピッチモーメント算出部30による算出値を補正するピッチレイト補正部53と、を有している。【選択図】 図2
