To determine a change in driving trend caused by driving over a long period.SOLUTION: A driving trend analysis system comprises: a sensor data acquisition unit 601 for acquiring sensor data indicating a motion of a vehicle; a driving behavior information acquisition unit 602 for sequentially acquiring information which indicates a driving behavior by a driver of the vehicle after an engine of the vehicle turns on; a holding unit for holding, as initial sensor data, sensor data which is acquired by the sensor data acquisition unit at a first acquisition of information which indicates the driving behavior by the driving behavior information acquisition unit; a calculation unit 604 for calculating non-similarity between the sensor data acquired by the sensor data acquisition unit and the initial sensor data, each time the driving behavior information acquisition unit acquires the information indicating the driving behavior for a second time and onward; and a determination unit 605 for, if the non-similarity calculated by the calculation part exceeds a prescribed threshold, determining that a change has occurred in information indicating the driving behavior by the driver of the vehicle.SELECTED DRAWING: Figure 6

    【課題】長時間の運転に起因する運転傾向の変化を判定する。【解決手段】運転傾向解析システムは、車両の動作を示すセンサデータを取得するセンサデータ取得部601と、前記車両のエンジンがON状態となって以降の、前記車両の運転者による運転行動を示す情報を、順次、取得する運転行動情報取得部602と、前記運転行動情報取得部が前記運転行動を示す情報を1回目に取得した際に前記センサデータ取得部が取得したセンサデータを、初期センサデータとして保持する保持部と、前記運転行動情報取得部が前記運転行動を示す情報を2回目以降に取得するごとに前記センサデータ取得部が取得したセンサデータと、前記初期センサデータとの非類似度を算出する算出部604と、前記算出部が算出した非類似度が、所定の閾値を超えた場合に、前記車両の運転者による運転行動を示す情報に、変化が発生したと判定する判定部605とを有する。【選択図】図6
