PROBLEM TO BE SOLVED: To provide a technology which can suppress a change of a posture of a vehicle main body in a vehicle height adjusting process.SOLUTION: Target relative positions of a front-wheel side relative position in which a vehicle height is set to a target vehicle height when raising the vehicle height up to the target vehicle height, and a rear-wheel side relative position are set, and when a speed ratio of a front-wheel side ratio of an actual change speed with respect to a reference speed about a change speed of the front-wheel side relative position, and a rear-wheel side ratio of the actual speed change with respect to the reference speed about a change speed of the rear-wheel side relative position is out of a prescribed range, the target position of the front-wheel side relative position or the rear-wheel side relative position is corrected so that a larger ratio in the front-wheel side ratio and in the rear-wheel side ratio coincides with a smaller ratio. Thus, a vehicle height is controlled so that the speed ratio falls within the prescribed range.
【課題】車高の調整過程において車両本体の姿勢が変化することを抑制することができる技術を提供する。【解決手段】車高を目標車高まで上昇させる際に目標車高にする前輪側相対位置および後輪側相対位置の目標の相対位置を設定し、前輪側相対位置の変化速度についての基準速度に対する実際の変化速度の前輪側比率と、後輪側相対位置の変化速度についての基準速度に対する実際の変化速度の後輪側比率との速度比率が所定範囲外である場合には、前輪側比率および後輪側比率の内の大きい方の比率を小さい方の比率に合わせるように、前輪側相対位置または後輪側相対位置の目標位置を補正することで、速度比率が所定範囲内となるように制御する。【選択図】図16
