To provide a device which executes emergency brake support for avoiding a collision when detecting an object that has a risk of colliding with a vehicle in the travel direction of the vehicle, and enables actuation of the brake support by determining that there is no acceleration intention in a driver when an accelerator pedal is kept to be stepped on for maintaining the vehicle speed around the maximum speed in a configuration that prohibits the brake support in a case where there is the acceleration intention in the driver.SOLUTION: An emergency brake support device of a vehicle determines the possibility of the brake support actuation so as to prohibit the actuation of the brake support when the duration of a state where the accelerator opening of the vehicle exceeds prescribed opening and a vehicle speed exceeds a prescribed speed is less than the prescribed time, and permit the brake support actuation when the accelerator opening is lower than the prescribed opening and the duration of a state where the accelerator opening exceeds the prescribed opening and the vehicle speed exceeds the prescribed speed is longer than the prescribed time.SELECTED DRAWING: Figure 2
【課題】 車両の進行方向に車両と衝突するおそれのある物体を検出すると、衝突回避のための緊急制動支援を実施する装置であって、運転者に加速意図があるときには、制動支援を禁止する構成に於いて、最高速度付近での車速維持のためにアクセルペダルが踏み続けられるときには、運転者に加速意図は無いと判定して、制動支援の作動を有効にすること。【解決手段】 車両の緊急制動支援装置は、車両のアクセル開度が所定開度を上回っており、車速が所定速度を上回っている状態の継続時間が所定時間に満たないときには、制動支援の作動を禁止する一方、アクセル開度が所定開度を下回っているとき及びアクセル開度が所定開度を上回っており、車速が所定速度を上回っている状態の継続時間が所定時間を超えているときには、制動支援作動を許可するように制動支援作動の可否を決定する。【選択図】 図2
