WIRELESS COMMUNICATION SYSTEM
To provide a wireless communication system capable of improving a security level even while suppressing the number of bits of a wireless signal that is transmitted from portable equipment.SOLUTION: A wireless communication system comprises a vehicle ECU 23 for executing control of a door lock mechanism 21 of a vehicle 20 based on a collation signal Sv (regular signal) that is transmitted from portable equipment 10 to the vehicle 20. The vehicle ECU 23 then shifts to a guard state (guard flag set state) based on a judgement that an irregular wireless signal which is not transmitted from regular portable equipment 10, is received by the vehicle 20. In the guard state, the control of the door lock mechanism 21 is executed on a condition that processing from reception of a wireless signal to collation establishment of the wireless signal is performed multiple times.SELECTED DRAWING: Figure 1
【課題】携帯機から送信される無線信号のビット数を抑えつつもセキュリティレベルを向上させることができる無線通信システムを提供する。【解決手段】無線通信システムは、携帯機１０から車両２０に送信された照合信号Ｓｖ（正規信号）に基づいて車両２０のドアロック機構２１の制御を実行する車両ＥＣＵ２３を備える。そして、車両ＥＣＵ２３は、正規の携帯機１０から送信されたものでない不正な無線信号を車両２０で受信した旨の判断に基づいて警戒状態（警戒フラグのセット状態）に移行し、該警戒状態においては、無線信号の受信から当該無線信号の照合成立までの処理が複数回なされることを条件にドアロック機構２１の制御を実行する。【選択図】図１
