To provide a vehicle posture control device that enables operability of steering by a driver to be improved without complicating configuration of a suspension.SOLUTION: A posture control device 4 comprises: reference longitudinal acceleration calculation means 23; reference yaw-rate calculation means 14; target pitch motion setting means 15; and command value correction means 16 that corrects a braking/driving force command value and a rear-wheel steering angle command value so that vehicle body motion approximately matches reference longitudinal acceleration, reference yaw-rate and target pitch motion. The command value correction means 16 has ratio setting means 16a that sets a ratio α of magnitude of pitch moments generated by correcting the rear-wheel steering angle command value in the sum of the pitch moments generated by the correction, the command value correction means 16 performing the correction using the ratio α. The ratio setting means 16a sets the ratio α on the basis of magnitude of the pitch moments generated by correcting the braking/driving force command value and the rear-wheel steering angle command value or magnitude of the rear-wheel steering angle command value.SELECTED DRAWING: Figure 8

    【課題】サスペンションの構成を複雑化することなく運転者の操舵の運転操作性を向上させることができる車両の姿勢制御装置を提供する。【解決手段】姿勢制御装置4は、基準前後加速度演算手段23と、基準ヨーレート演算手段14と、目標ピッチ運動設定手段15と、車体運動が、基準前後加速度、基準ヨーレートおよび目標ピッチ運動と略一致するように、制駆動力指令値および後輪舵角指令値を補正する指令値補正手段16とを備える。指令値補正手段16は、補正により発生するピッチモーメントの総和における、後輪舵角指令値を補正することで発生するピッチモーメントの大きさの比率αを設定する比率設定手段16aを有し、比率αを用いて補正を行い、比率設定手段16aは、制駆動力指令値および後輪舵角指令値を補正することで発生するピッチモーメントの大きさまたは後輪舵角指令値の大きさに基づいて比率αを設定する。【選択図】図8
