To provide a device, a method, and a program by which highly accurate abnormality detection is realized.SOLUTION: An abnormality detection device 100 includes a condition generating unit 230, a threshold setting unit 220, and an abnormality detecting unit 110. The condition generating unit generates a plurality of conditions sectioning a difference between a prediction value of a vehicle condition based on a control command value and a prediction model and a measured value of the vehicle condition on the basis of traveling information of the vehicle. The threshold setting unit sets a plurality of threshold values with respect to the plurality of conditions. The abnormality detecting unit detects an abnormality of a vehicle on the basis of the prediction model, the plurality of threshold values, and the plurality of conditions.SELECTED DRAWING: Figure 1
【課題】精度の高い異常検知を実現する装置、方法及びプログラムを提供する。【解決手段】異常検知装置100は、条件生成部230と、閾値設定部220と、異常検知部110とを備える。条件生成部は、制御指令値と予測モデルとに基づく車両の状態の予測値と、車両の状態の計測値との差分を区分する複数の条件を、車両の走行情報に基づいて、生成する。閾値設定部は、複数の条件に対し複数の閾値を設定する。異常検知部は、予測モデルと、複数の閾値と、複数の条件とに基づき、車両の異常検知を行う。【選択図】図1
