PROBLEM TO BE SOLVED: To properly unlock a door of a vehicle by performing determination of a relay attack with high accuracy.SOLUTION: A vehicle door unlocking system comprises a portable machine including identification information, and an on-vehicle device mounted in a vehicle for communicating with the portable machine to unlock a door of the vehicle. The portable machine measures a portable machine distance which is a distance from the vehicle to the portable machine, and transmits the measured portable machine distance and its own identification information to the on-vehicle device. The on-vehicle device unlocks the door of the vehicle when the identification information received from the portable machine is a pre-registered information, and also when the portable machine distance received from the portable machine is less than a predetermined distance.SELECTED DRAWING: Figure 1

    【課題】リレーアタックの判定を高い精度で行うことによって、車両のドアを適切に解錠する。【解決手段】本発明の車両ドア解錠システムは、識別情報を有する携帯機と、車両に搭載されて、携帯機と通信を行うことによって車両のドアを解錠する車載装置とを備える。これらのうち、携帯機は、車両から当該携帯機までの距離である携帯機距離を計測し、計測した携帯機距離と自己の識別情報とを車載装置に送信する。車載装置は、携帯機から受信した識別情報が予め登録された情報であり、且つ、携帯機から受信した携帯機距離が所定の距離未満である場合に、車両のドアを解錠する。【選択図】図1
