To easily and accurately detect whether or not there is a door pinch.SOLUTION: A door pinch detection device that detects a door pinch when a door is driven in a closed direction by driving force of a motor includes: a first acquisition unit that acquires a first current value flowing through the motor during a first period when the door is in a closing operation; a threshold setting unit that sets a threshold for determining a door pinch based on the acquired first current value; a second acquisition unit that acquires a second current value flowing through the motor in a second period after the first period when the door is in the closing operation; and a determination unit that determines whether or not a door pinch has occurred by comparing the acquired second current value with the set threshold.SELECTED DRAWING: Figure 5

    【課題】戸挟みが生じたか否かを簡易かつ正確に検出する。【解決手段】モータの駆動力によってドアが閉方向に駆動される際の戸挟みを検出する戸挟み検出装置は、ドアの閉動作中の第1期間にモータに流れる第1電流値を取得する第1取得部と、取得された第1電流値に基づいて、戸挟みを判定するための閾値を設定する閾値設定部と、ドアの閉動作中の第1期間の後である第2期間にモータに流れる第2電流値を取得する第2取得部と、取得された第2電流値と設定された閾値とを比較することにより、戸挟みが生じたか否かを判定する判定部と、を備える。【選択図】図5
