To provide an approach arrester which can perform a control for preventing approaching of a subsequent vehicle to an own vehicle at a suitable timing, and an approach prevention method.SOLUTION: An approach arrester 10 comprises: a warning control part 34 which is mounted on an own vehicle, and performs warning control for preventing approaching of a subsequent vehicle to an own vehicle (preceding vehicle); an acceleration sensor 53 which acquires an acceleration of the own vehicle; a subsequent vehicle acceleration calculation part 33 which acquires an acceleration of the subsequent vehicle; and a warning control start condition determination part 35 which determines start condition of warning control according to a degree of difference between a mode of change of the own vehicle acceleration in a prescribed period which is recognized from time-sequence data of an acceleration of the own vehicle and a mode of change of the subsequent vehicle acceleration in a prescribed period which is recognized from time-sequence data of an acceleration of the subsequent vehicle.SELECTED DRAWING: Figure 2
【課題】後続車両の自車両への接近を防止するための制御を適切なタイミングで実施できる接近防止装置、及び接近防止方法を提供する。【解決手段】接近防止装置10は、自車両に搭載され、後続車両の自車両(先行車両)への接近を防止するための警告制御を行う警告制御部34と、自車両の加速度を取得する加速度センサ53と、後続車両の加速度を取得する後続車両加速度算出部33と、自車両の加速度の時系列データから認識した所定期間における自車両の加速度の変化の態様と、後続車両の加速度の時系列データから認識した所定期間における後続車両の加速度の変化の態様との相違度合に応じて警告制御の開始条件を決定する警告制御開始条件決定部35とを備える。【選択図】図2
