ON-VEHICLE EQUIPMENT CONTROL SYSTEM, ON-VEHICLE CONTROL DEVICE, AND PORTABLE UNIT
PROBLEM TO BE SOLVED: To block a relay attack, and to leave traces of the relay attack.SOLUTION: A portable unit 20 comprises a mode changeover switch 24b for switching a permission mode to a prohibition mode, and an on-vehicle control device 10 comprises an illegality recording part 1a for, when a response request signal is transmitted from the on-vehicle control device 10 in the prohibition mode, recording this as an illegality history. When the response request signal transmitted from the on-vehicle control device 10 is received by the portable unit 20 in the permission mode, the portable unit 20 transmits a response signal, and when receiving the response signal, the on-vehicle control device 10 controls a door lock device 7 on the basis of the response signal such that the door of a vehicle 30 is locked/unlocked. When the response request signal transmitted from the on-vehicle control device 10 is received by the portable unit 20 in the prohibition mode, the portable unit 20 transmits an illegality notification signal, and when receiving the illegality notification signal, the on-vehicle control device 10 does not control the door lock device 7 such that the door of the vehicle 30 is not locked/unlocked.SELECTED DRAWING: Figure 1
【課題】リレーアタックを阻止し、かつリレーアタックの痕跡を残す。【解決手段】許可モードと禁止モードとを切り替えるモード切替スイッチ２４ｂを携帯機２０に備え、禁止モード中に応答要求信号が車載制御装置１０から送信された場合に、これを不正履歴として記録する不正記録部１ａを車載制御装置１０に備える。許可モード中に、車載制御装置１０から送信された応答要求信号が携帯機２０で受信されると、携帯機２０が応答信号を送信し、車載制御装置１０は応答信号を受信すると、当該応答信号に基づいてドアロック装置７を制御して、車両３０のドアを施解錠する。禁止モード中に、車載制御装置１０から送信された応答要求信号が携帯機２０で受信されると、携帯機２０が不正通知信号を送信し、車載制御装置１０は不正通知信号を受信すると、ドアロック装置７を制御せず、車両３０のドアを施解錠しない。【選択図】図１
