To provide an automatic brake device that is advantageous in suppressing deflection of a vehicle so as to ensure braking effect when the vehicle has a tendency of laterally eccentric load.SOLUTION: An automatic brake device for a vehicle comprises: means (11) for detecting an obstacle in front of a traveling direction; an automatic brake control part (10) for issuing a brake request when a collision against the obstacle is predicted; and a brake actuator (20) for operating automatic brake in accordance with the brake request. The automatic brake device further comprises a yaw rate detection part (22) for detecting a yaw rate of the vehicle. When the yaw rate detection part detects that a value of the deflection of the vehicle reaches or exceeds a threshold value during automatic brake operation based on the brake request, a value of the brake request is configured to be changed to a value smaller than that of the case where the deflection is less than the threshold value.SELECTED DRAWING: Figure 1

    【課題】 左右の偏荷重傾向がある場合における車両の偏向を抑制し、制動効果を確保するうえで有利な自動ブレーキ装置を提供する。【解決手段】 進行方向前方の障害物を検知する手段(11)と、前記障害物との衝突が予測される場合にブレーキ要求を出す自動ブレーキ制御部(10)と、前記ブレーキ要求に従い自動ブレーキを作動させるブレーキアクチュエータ(20)と、を備えた車両の自動ブレーキ装置において、前記車両のヨーレートを検知するヨーレート検知部(22)をさらに備え、前記ブレーキ要求による自動ブレーキの作動中に、前記ヨーレート検知部により車両の偏向が閾値以上となったことを検知した時に、前記ブレーキ要求の値が、前記偏向が前記閾値未満である場合よりも小さい値に変更されるように構成されている、【選択図】 図1
