To prevent erroneous detection of a parking state in a detection object parking area.SOLUTION: A parking detection device includes: a magnetism detection section for detecting a first magnetism in a height direction of a first parking area and a second magnetism in a crossing direction to cross with the height direction; a time difference calculation section for calculating a time difference between a point of time when a first change speed being the speed to change the first magnetism is returned to a pre-increase state after increasing and a point of time when a second change speed being the speed to change the second magnetism is returned to a pre-increase state after increasing; and a determination section for determining parking states of the first parking area and a second parking area adjacent to the first parking area based on the time difference.SELECTED DRAWING: Figure 4

    【課題】検知対象の駐車領域において、駐車状態の誤検知を防止すること。【解決手段】駐車検知装置は、第1駐車領域の高さ方向の第1磁気と、高さ方向に交差する交差方向の第2磁気と、を検知する磁気検知部と、第1磁気が変化する速度である第1変化速度が増加した後に増加前の状態に戻る時点と、第2磁気が変化する速度である第2変化速度が増加した後に増加前の状態に戻る時点との時間差を算出する時間差算出部と、時間差に基づいて、第1駐車領域及び当該第1駐車領域に隣接する第2駐車領域の駐車状態を判定する判定部と、を備える。【選択図】図4
