PORTABLE DEVICE AND REMOTE KEYLESS ENTRY SYSTEM
To provide a portable device and a remote keyless entry system capable of detecting with accuracy a relay attack on a vehicle mounted with a RKE system.SOLUTION: A portable device according to an embodiment is provided with: a receiver receiving vehicular on-board device signals including a determination signal of which a signal level has a specific part; a controller determining whether the vehicular on-board device signal is a correct one based on a wave shape in an object region of the determination signal of which the signal level has the specific part; and a transmitter transmitting a portable device signal corresponding with a result of the vehicular on-board device signal.SELECTED DRAWING: Figure 4
【課題】 ＲＫＥシステムを搭載した車両に対するリレーアタックを精度よく検出する。【解決手段】 一実施形態に係る携帯機は、信号レベルが一定の部分を有する判定信号を含む車載器信号を受信する受信部と、前記信号レベルが一定の部分を有する前記判定信号の対象部分の波形に基づいて、前記車載器信号が正規の信号であるか判定する制御部と、前記車載器信号の判定結果に応じた携帯機信号を送信する送信部と、を備える。【選択図】 図４
