PROBLEM TO BE SOLVED: To provide a vehicular anti-theft device with high security in which engine starting can be certainly prohibited in a case that a control device controlling engine starting and an anti-theft function of a vehicle is illicitly exchanged.SOLUTION: When an engine control ECU3 and a crime-preventing module 4 controlling a crime-preventing function are connected electrically to each other as the first time, each ID is registered by the ID authentication part 6, 10 of the other through tying up. Thereafter, whenever starting an engine, mutual ID authentication is implemented between the ECU3 and the ID authentication part 6, 10 of the crime-preventing module 4, engine starting is permitted providing ID matches at both sides. In a case of mismatch of either side ID or both side IDs, it is regarded as illicit exchange of the ECU3 or the crime-preventing module 4 and engine starting is prohibited.SELECTED DRAWING: Figure 1

    【課題】車両のエンジン始動や防犯機能を司る制御装置が不正に交換されたときに確実にエンジン始動を禁止できる高いセキュリティを有する車両の盗難防止装置を提供する。【解決手段】エンジン制御用のECU3と防犯機能を司る防犯モジュール4とが電気的に接続された当初に、互いのIDをそれぞれのID認証部6,10で紐付けて登録し、以降はエンジン始動毎にECU3と防犯モジュール4のID認証部6,10の間で互いのIDを相互認証し、双方でのID一致を条件としてエンジン始動を許可し、何れか一方のIDまたは双方のIDが不一致の場合にはECU3または防犯モジュール4の不正交換と見なしてエンジン始動を禁止する。【選択図】図1
