To reduce shift between timing at which it is determined that a vehicle is stopped and timing at which the vehicle is actually stopped.SOLUTION: A stop determination device 1 comprises: a storage unit 11 which stores a discrimination function created by a pattern recognition model that uses an acceleration speed of a vehicle V and an integrated value obtained by integrating the acceleration speeds in such a period that a wheel speed of the vehicle V is equal to or less than a prescribed value as feature amounts; a wheel speed acquisition unit 121 which sequentially acquires the wheel speed of the vehicle V; an acceleration speed acquisition unit 123 which sequentially acquires the acceleration speed in a travel direction of the vehicle V; an integrated value calculation unit 124 which calculates the integrated value by integrating the acceleration speeds acquired in such a period that the wheel speed is continuously equal to or less than the prescribed value; a discrimination value calculation unit 125 which calculates a discrimination value for determining whether the vehicle V is stopped by substituting the newly acquired acceleration speed and integrated value into the discrimination function; and a stop determination unit 126 which determines that the vehicle V travels in such a period that the calculated discrimination value is less than a prescribed determination threshold and determines that the vehicle V is stopped when the discrimination value is equal to or greater than the prescribed determination threshold.SELECTED DRAWING: Figure 1
【課題】車両が停止したと判定するタイミングと実際に車両が停止したタイミングとのずれを低減する。【解決手段】停止判定装置1は、車両Vの加速度と、車両Vの車輪速が所定値以下の間の加速度を積分した積分値とを特徴量とするパターン認識モデルによって作成された識別関数を記憶する記憶部11と、車両Vの車輪速を順次取得する車輪速取得部121と、車両Vの進行方向の加速度を順次取得する加速度取得部123と、車輪速が継続して所定値以下である間に取得した加速度を積分して積分値を算出する積分値算出部124と、新たに取得した加速度及び積分値を識別関数に代入して車両Vが停止しているか否かを判定するための識別値を算出する識別値算出部125と、算出した識別値が所定の判定閾値未満である間、車両Vが走行していると判定し、識別値が所定の判定閾値以上になったら、車両Vが停止していると判定する停止判定部126と、を備える。【選択図】図1
