PROBLEM TO BE SOLVED: To achieve a method for determining a rapid deceleration accurately from a small amount of sensor information.SOLUTION: A rapid deceleration determination method includes: a GPS speed obtaining step of obtaining a speed of a mobile body on the basis of GPS reception information; an acceleration obtaining step of obtaining composite acceleration of a three-axis acceleration sensor; a travel direction obtaining step of obtaining a travel direction of the mobile body on the basis of the GPS reception information; and a rapid deceleration determination step of determining occurrence of rapid deceleration of the mobile body on the basis of the speed, the composite acceleration and the travel direction. Further, the rapid deceleration determination method can include a rapid deceleration notification step of notifying a communication unit of the determined occurrence of the rapid deceleration.SELECTED DRAWING: Figure 4

    【課題】少ないセンサの情報から正確に急減速が判定できる方法を実現する。【解決手段】急減速判定方法は、GPS受信情報に基づき移動体の速度を取得するGPS速度取得ステップと、3軸加速度センサの合成加速度を取得する加速度取得ステップと、GPS受信情報に基づいて移動体の進行方向を取得する進行方向取得ステップと、速度と、合成加速度と、進行方向とに基づいて、移動体の急減速発生を判定する急減速判定ステップと、を含む。さらに急減速判定方法は、判定された急減速発生を通信ユニットへ通知する急減速通知ステップを含んでもよい。【選択図】図4
