PROBLEM TO BE SOLVED: To provide an abnormality detection apparatus capable of detecting sticking of a switch.SOLUTION: An abnormality detection apparatus, used for detecting abnormality of a switch that operates in response to opening-closing of a hood, includes: an engine detection part for detecting a state of an engine; a charge-discharge detection part for detecting a charge-discharge state of a power storage device accessible when the hood is open; and an abnormality determination part for detecting whether a switch is stuck on the basis of an engine state and the charge-discharge state of the power storage device. Further, in a case where the engine is turned off, with the power storage device charge-discharge state and the switch state indicating the hood being closed, the abnormality determination part determines that the switch is stuck.SELECTED DRAWING: Figure 2
【課題】スイッチの固着を検出することが可能な異常検出装置を提供すること。【解決手段】フードの開閉状態に応じて動作するスイッチの異常を検出する異常検出装置であって、エンジンの状態を検出するエンジン検出部と、フードが開状態のときにアクセス可能な蓄電装置の充放電状態を検出する充放電検出部と、エンジンの状態、蓄電装置の充放電状態及びスイッチの状態に基づいて、スイッチが固着しているか否かを判定する異常判定部とを有し、異常判定部は、エンジンがエンジンオフ状態、蓄電装置が充放電状態及びスイッチがフードの閉状態を示す状態である場合、スイッチが固着していると判定する。【選択図】図2
