To notify a driver of an own vehicle, of the magnitude of a temporally changing risk of collision between the own vehicle and a preceding vehicle, in a manner close to the perception of a skilled driver.SOLUTION: An attention calling system includes: a time headway (THW) acquisition unit that repeatedly acquires THW at predetermined time intervals, the THW being a value obtained by dividing an inter-vehicle distance between own vehicle and a preceding vehicle by vehicle speed of the own vehicle; an identification unit that identifies a type of the preceding vehicle; and a notification unit that outputs to an occupant of the own vehicle an approach alarm that notifies of an approach to the preceding vehicle when the THW becomes a first threshold or less. The notification unit outputs the approach alarm using the first threshold that takes different values depending on the type of the preceding vehicle, and/or by setting a saliency level that is a degree of saliency of the approach alarm to a first level that has different magnitudes depending on the type of the preceding vehicle.SELECTED DRAWING: Figure 6

    【課題】時間的に変化する自車両と先行車との衝突リスクの大きさを、熟練運転者の主観に近い態様で自車両の運転者に伝達する。【解決手段】注意喚起システムは、自車両と先行車との間の車間距離を自車両の車速で除算した値である車間時間を所定の時間間隔で繰り返し取得するTHW取得部と、先行車の種類を識別する識別部と、車間時間が第1閾値以下となったときに先行車への接近を報知する接近警報を自車両の乗員に対して出力する報知部と、を備え、報知部は、先行車の種類に応じて異なる値の第1閾値を用いて、及び又は、接近警報の顕著性の程度である顕著性レベルを、先行車の種類に応じて異なる大きさを有する第1レベルに設定して、上記接近警報を出力する。【選択図】図6
