KEYLESS ENTRY SYSTEM FOR VEHICLE
PROBLEM TO BE SOLVED: To prevent illegal unlocking of a vehicle door and to improve security.SOLUTION: Storage parts 103, 204 of a portable machine 10 and an on-vehicle machine 20 store a signal pattern list in which a plurality of signal patterns used for generation and reception of an operation signal are consolidated. A pattern determination part 219 for the on-vehicle machine 20 performs determination of a signal pattern of the operation signal, and in the case where the determination is established, it performs collation of a portable machine side counter code and an on-vehicle machine side counter code of the operation signal. In the case where the collation is established, the pattern determination part 219 locks or unlocks the door of a vehicle, and an update part 203 updates the on-vehicle side counter code. In passive communication between the portable machine 10 and the on-vehicle machine 20, pattern determination parts 107, 218 change a signal pattern used for generation and reception of the operation signal.SELECTED DRAWING: Figure 5
【課題】車両のドアの不正解錠を防止し、セキュリティを向上させる。【解決手段】携帯機１０と車載機２０の記憶部１０３、２０４は、操作信号の生成および受信に用いる複数の信号パターンをまとめた信号パターンリストを記憶する。車載機２０のパターン判定部２１９は、操作信号の信号パターンの判定を行い、判定が成立した場合に操作信号の携帯機側カウンタコードと車載機側カウンタコードの照合を行う。照合が成立した場合、パターン判定部２１９は車両のドアを施錠または解錠させ、更新部２０３が車載機側カウンタコードを更新する。携帯機１０と車載機２０間のパッシブ通信において、パターン決定部１０７、２１８は、操作信号の生成および受信に用いる信号パターンを変更する。【選択図】図５
