To accurately detect an illegal action applied to a vehicle while preventing a possibility of the erroneous detection of the illegal action to the vehicle by a first detection part even if it is determined that the vehicle is in an alert state, and the vehicle is operated according to a remote operation requirement.SOLUTION: This theft prevention device comprises, as one example: a first detection part for detecting an illegal action to a vehicle; a second detection part for detecting a state of an occupant who has boarded on the vehicle; a determination part for determining whether or not a state of the vehicle is an alert state that the occupant gets off from the vehicle; a first control part for operating the vehicle according to a remote operation requirement which is received from an external device; and a second control part for invalidating the first detection part, or lowering the detection sensitivity of the first detection part when the alert state is determined and the vehicle is operated according to the remote operation requirement, and detecting the illegal action to the vehicle by using the second detection part.SELECTED DRAWING: Figure 3

    【課題】車両が警戒状態であると判定されかつ遠隔作動要求に応じて車両を作動させる場合でも、第1検出部による車両に対する不正行為の誤検出の可能性を防止しつつ、車両に対する不正行為を高精度に検出する。【解決手段】実施形態の盗難防止装置は、一例として、車両に対する不正行為を検出する第1検出部と、車両に乗車した乗員の状態を検出する第2検出部と、車両の状態が、当該車両から乗員が降車した警戒状態か否かを判定する判定部と、外部装置から受信する遠隔作動要求に応じて車両を作動させる第1制御部と、警戒状態と判定されかつ遠隔作動要求に応じて車両を作動させる場合、第1検出部を無効化するか若しくは第1検出部の検出感度を下げ、かつ第2検出部を用いて、車両に対する不正行為を検出する第2制御部と、を備える。【選択図】図3
