PROBLEM TO BE SOLVED: To provide a collision notification device for vehicle in which determination criteria whether or not a collision risk of own vehicle is present is set every predetermined time on the basis of the acceleration/deceleration operating condition of a driver, and thereby collision notification is possible in the timing proper for the driver.SOLUTION: A collision notification device 1 sets a collision avoidance time based on an accelerator depression amount longer than a predetermined TTC or the collision avoidance time based on acceleration as a TTC threshold value (S107, S108), when a determination is made that a driver is in acceleration operation (S103:Yes). Also, when the determination is made that the driver is in deceleration operation (S109:Yes), the collision avoidance time based on a brake depression amount shorter than the predetermined TTC or the collision avoidance time based on the deceleration are set as a TTC threshold value (S113, S114). The calculation TTC is compared with this TTC threshold value, and thereby the determination is made whether the collision risk is present (S124), and the collision notification is performed to the driver (S125).SELECTED DRAWING: Figure 2

    【課題】運転者の加減速操作状態に基づいて、自車両の衝突危険性があるか否かの判定基準を所定時間毎に設定することで、運転者にとって適切なタイミングで衝突報知が可能な車両用衝突報知装置を提供する。【解決手段】衝突報知装置1は、運転者が加速操作中であると判定した場合(S103:Yes)、所定TTCよりも長いアクセル踏み込み量に基づく衝突回避時間、または加速度に基づく衝突回避時間をTTC閾値として設定する(S107、S108)また、運転者が減速操作中であると判定した場合(S109:Yes)、所定TTCよりも短いブレーキ踏み込み量に基づく衝突回避時間、または減速度に基づく衝突回避時間をTTC閾値として設定する(S113、S114)。このTTC閾値と算出TTCとを比較することで、衝突危険性があるか否かを判定し(S124)、運転者に衝突報知を行う(S125)。【選択図】図2
