PROBLEM TO BE SOLVED: To provide a technology for accurately determining the axis deviation of a rader device mounted on a vehicle.SOLUTION: An axis deviation determining device includes: first detection value obtaining means for obtaining a first detection value by a first acceleration sensor which detects acceleration added to a rader device; second detection value obtaining means for obtaining a second detection value by a second acceleration sensor which detects acceleration added to a vehicle body; difference calculating means for calculating a detection difference value which is difference between the first detection value and the second detection value, at every first period; average difference value calculating means for calculating an average difference value which is an average value about a plurality of detection difference values calculated by the difference calculating means in an obtaining period of length including the plurality of first periods; deviation calculating means for calculating a difference reference deviation which is a reference deviation about the plurality of detection difference values calculated by the difference calculating means in the obtaining period; and determining means (S150-S170) for determining an axis deviation generated in the rader device on the basis of the average difference value and the difference reference deviation.

    【課題】車両に搭載されるレーダ装置の軸ずれを精度よく判定する技術を提供する。【解決手段】レーダ装置に加わる加速度を検出する第1の加速度センサによる第1の検出値を取得する第1の検出値取得手段と、車両本体に加わる加速度を検出する第2の加速度センサによる第2の検出値を取得する第2の検出値取得手段と、第1の検出値と第2の検出値との差分である検出差分値を第1の周期毎に算出する差分算出手段と、第1の周期を複数含む長さの期間である取得期間内に差分算出手段により算出された複数の検出差分値についての平均的な値である平均的差分値を算出する平均的差分値算出手段と、取得期間内に差分算出手段により算出された複数の検出差分値についての標準偏差である差分標準偏差を算出する偏差算出手段と、平均的差分値及び差分標準偏差に基づいて、レーダ装置に生じた軸ずれを判定する判定手段(S150−S170)と、を備える。【選択図】図5
