PROBLEM TO BE SOLVED: To provide a technique for distributing a processing load to detect an abnormality in a road state.SOLUTION: A model storage section 24 of an on-vehicle abnormality detection device stores a driving model that is set in response to a travel position of a vehicle and expresses a normal driving state when the vehicle travels at the travel position. A data acquisition section 32 acquires vehicle driving data expressing a driving state. An abnormality level calculation section 38 calculates an abnormality level of a driving state on the basis of a driving model stored by the model storage section and driving data to be acquired by the data acquisition section. A transmission section 26 transmits at least an abnormality level and a travel position corresponding to the abnormality level to a management device 40 of a management center outside of a vehicle, that detects an abnormality of a road state on the basis of the abnormality level when the abnormality level of a driving state exceeds an abnormality determination value.SELECTED DRAWING: Figure 1
【課題】道路状況の異常を検出するための処理負荷を分散させる技術を提供する。【解決手段】車載の異常検出装置のモデル格納部24は、車両の走行位置に対応して設定されており走行位置を車両が走行するときの通常の運転状態を表す運転モデルを格納する。データ取得部32は、運転状態を表す車両の運転データを取得する。異常度算出部38は、モデル格納部が格納している運転モデルとデータ取得部が取得する運転データとに基づいて運転状態の異常度を算出する。送信部26は、運転状態の異常度が異常判定値を越えている場合、異常度に基づいて道路状況の異常を検出する車両の外部の管理センタの管理装置40に異常度と異常度に対応する走行位置とを少なくとも送信する。【選択図】図1
