To provide an automatic braking device in which such a problem that an obstacle is erroneously determined as an oncoming vehicle can be suppressed.SOLUTION: The automatic braking device determining possibility of collision with an obstacle and performing automatic braking is provided that comprises: information acquisition means which acquires a distance to the obstacle, a relative speed of an own vehicle and the obstacle, and a speed of the own vehicle; an oncoming vehicle determination part 22 which determines whether the obstacle is an oncoming vehicle or not by comparing a calculated value which is on the basis of the relative speed and the speed of the own vehicle with a determination threshold; and a threshold setting part 222 which sets the determination threshold according to the distance to the obstacle and the speed of the own vehicle. Automatic control is regulated when it is determined by the oncoming vehicle determination part 22 that the obstacle is an oncoming vehicle.SELECTED DRAWING: Figure 1
【課題】対向車であると誤って判断することを抑制できる自動制動装置を提供する。【解決手段】障害物との衝突の可能性を判断して、自動制動を行う自動制動装置において、障害物との距離、自車と障害物との相対速度、および自車速を取得する情報取得手段と、相対速度および自車速に基づく演算値と、判定閾値との比較により、障害物が対向車であるか否かを判断する対向車判断部22と、障害物との距離または自車速に応じて判定閾値を設定する閾値設定部222とを備え、対向車判断部22によって、障害物が対向車であると判断された場合には、自動制動を規制するようにした。【選択図】図1
