To provide a vehicle attitude control device capable of suppressing uplift of an inner rear part of a vehicle body during turning in a vehicle in which a roll axis of the vehicle body is set to tilt forward.SOLUTION: A vehicle attitude control device for controlling an attitude of a vehicle (1) in which a wheel suspension device (3) is configured such that a roll axis inclines downwardly in a forward direction. The vehicle attitude control device includes: a lateral acceleration sensor (22) for detecting lateral acceleration of the vehicle while traveling; a brake actuator (8) for applying braking force to a wheel of the vehicle; and a brake control device (14a), based on a traveling state of the vehicle, for sending a control signal to the brake actuator to generate the braking force. While the vehicle is turning and traveling based on a cutting-in operation of a steering wheel (6) of the vehicle, when the lateral acceleration of the vehicle is large, the brake control device applies, to an inner rear wheel of the vehicle during turning, braking force larger than that when the lateral acceleration of the vehicle is small, to execute attitude control of the vehicle for suppressing uplift of an inner rear part of a vehicle body.SELECTED DRAWING: Figure 7

    【課題】ロール軸が前傾するように設定された車両において、旋回時に車体の内側後部が浮き上がるのを抑制することができる車両姿勢制御装置を提供する。【解決手段】本発明は、ロール軸が前傾するように車輪懸架装置(3)が構成された車両(1)の姿勢を制御する車両姿勢制御装置であって、走行中の車両の横加速度を検出する横加速度センサ(22)と、車両の車輪に制動力を作用させるブレーキアクチュエータ(8)と、車両の走行状態に基づいて、ブレーキアクチュエータに制御信号を送り、制動力を発生させるブレーキ制御装置(14a)と、を有し、ブレーキ制御装置は、車両のステアリングホイール(6)の切り込み操作に基づく車両の旋回走行時において、車両の横加速度が大きい場合には、車両の横加速度が小さい場合よりも大きな制動力を旋回中の車両の内側後輪に作用させて、車体内側後部の浮き上がりを抑制する車両姿勢制御を実行することを特徴としている。【選択図】図7
