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 magnetisms (a first magnetism in a height direction of a first parking area, a second magnetism in a first crossing direction to cross with the height direction, and a third magnetism in a second crossing direction to cross with the height direction and also to be different from the first crossing direction) in the first parking area; a difference value calculation section for calculating a difference value being a difference between the detected magnetisms and the magnetisms when the first parking area is in a vacant state; and a determination section for determining that a vehicle that has entered the first parking area has moved to a second parking area adjacent to the first parking area when the calculated difference value repeats increasing/decreasing.SELECTED DRAWING: Figure 7

    【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駐車領域において磁気(第1駐車領域の高さ方向の第1磁気、高さ方向に交差する第1交差方向の第2磁気、高さ方向に交差し、かつ、第1交差方向とは異なる第2交差方向の第3磁気)を検知する磁気検知部と、検知された磁気と、第1駐車領域が空車状態である場合の磁気との差分である差分値を算出する差分値算出部と、算出された差分値が増減を繰り返した場合、第1駐車領域に進入した車両が、第1駐車領域に隣接する第2駐車領域へ移動したと判定する判定部と、を備える。【選択図】図7
