To provide an abnormal driving action detection device, abnormal driving action detection method and program, capable of detecting an abnormal driving action concerning acceleration and deceleration operations by a driver with a simple configuration.SOLUTION: An abnormal driving action detection device 1 includes: vehicle acquisition means 12 for acquiring the vehicle speed of a vehicle 2; a storage section 11; vehicle speed estimation means 13; and abnormal action detection means 14. The storage section 11 stores information showing a vehicle speed acquired by the vehicle speed acquisition means 12 and a predetermined autoregression model M. The vehicle speed estimation means 13 estimates a vehicle speed at a predetermined point of time on the basis of the autoregression model M and a plurality of vehicle speeds at points of time different from each other, earlier than the predetermined point of time. The abnormal action detection means 14 detects an abnormal action when a difference between the vehicle speed acquired by the vehicle speed acquisition means 12 and the vehicle speed at the predetermined point of time estimated by the vehicle speed estimation means 13 is in excess of a predetermined threshold value.SELECTED DRAWING: Figure 1
【課題】簡易な構成で、運転者による加減速操作に関する異常行動を検出することができる異常運転行動検出装置、異常運転行動検出方法、及びプログラムを提供する。【解決手段】異常運転行動検出装置1は、車両2の車速を取得する車速取得手段12と、記憶部11と、車速推定手段13と、異常行動検出手段14とを備える。記憶部11は、車速取得手段12が取得した車速と、所定時点の車速を推定するための予め定めた自己回帰モデルMとを示す情報を記憶する。車速推定手段13は、自己回帰モデルMと、所定時点よりも前の互いに異なる時点における複数の車速とに基づいて所定時点の車速を推定する。異常行動検出手段14は、車速取得手段12が取得した車速と、車速推定手段13が推定した所定時点の車速との差分が、予め定めた閾値を超えた場合に異常行動を検出する。【選択図】図1
