- the portable device A that has received the portable reply request updates the update number managed by itself from “1” to “2”, and the update number “2” and the portable code “ a ”is returned to the in-vehicle device 10.
- the in-vehicle device 10 that has received the mobile code “a” and the update number “2” generates information obtained by adding the update number “2” to the mobile code “a” as a new vehicle code “a2”, and the storage device The vehicle code registered in 34 is changed from “a1” to “a2”. Furthermore, when the in-vehicle device 10 registers the portable code “a” in association with the vehicle code “a2” and receives a completion notification from the portable device A, the key number managed by the in-vehicle device 10 itself is changed to “2”. And the process proceeds to registration for the next portable device C.
- the person who performs the information registration process arranges the portable device C so as to be positioned within the communication range of the short-range wireless antenna 26 instead of the portable device A.
- the in-vehicle device 10 transmits a portable response request to the portable device C.
- the portable device C that has received this portable response request registers the key number “2” and returns the portable code “c” assigned to the portable device C itself to the in-vehicle device 10.
- the in-vehicle device 10 that has received the portable code “c” registers the portable code “c” in association with the vehicle code “a2” stored in the storage device 34 and also stores the vehicle code in the portable device C. “A2” is transmitted. Receiving the vehicle code “a2”, the portable device C registers the vehicle code “a2” in association with the key number “2” and transmits a completion notification.
- the in-vehicle device 10 receives the completion notification from the portable device C, the in-vehicle registration process and thus re-registration ends.
- the new vehicle code “a2” and the portable code of each portable device 50 are registered in the in-vehicle device 10.
- the updated update number (“2”) is stored in the portable device A
- the vehicle code “2” is stored in the portable device C together with the key number “2” as the response timing of the portable device C in the authentication process. a2 "is registered.
- the electronic key system 1 functions as an information registration system for registering information necessary for the authentication process in the in-vehicle device 10 and the portable device 50.
- the in-vehicle device 10 transmits a response request including the vehicle code and the response timing, as shown in FIG. To do.
- the mobile devices A and C that have received this response request transmit the mobile code assigned to them at the response timing registered in the mobile device.
- each portable device 50 in the present embodiment determines whether or not the received vehicle code matches the vehicle code stored in itself when receiving a response request in the authentication process.
- Each portable device 50 generates a portable code by removing the update number from the received vehicle code when the two vehicle codes do not match or when the vehicle code is not stored in the portable device 50. Match the mobile code assigned to you. Further, each portable device 50 immediately transmits the portable code assigned to the portable device 50 itself when both portable codes match, and when both vehicle codes match, the portable device 50 The mobile code assigned to itself is transmitted at a response timing (key number) registered in the mobile device 50 itself. (Effects of the first embodiment) As described above, according to the electronic key system 1, it is possible to prevent a plurality of portable devices 50 in which the same information is registered from being generated.
- the electronic key system 1 as shown in FIG. 5, it is possible to prevent duplication of the timing when the portable device A and the portable device C return the portable codes. Furthermore, according to the electronic key system 1, the portable device B can be prevented from returning a portable code. As a result, according to the electronic key system 1, the occurrence of interference in the authentication process can be reduced, and the occurrence of a situation where the authentication process cannot be executed normally can be reduced.
- a new vehicle code is generated by adding an update number to the mobile code assigned to the mobile device 50 registered with “1” as the key number. Yes. Since this update number is updated each time the information registration process is executed, according to the electronic key system 1, the contents of the newly generated vehicle code are different each time the information registration process is executed. It can be. Moreover, the generation of the new vehicle code can be realized with a small amount of processing.
- the electronic key system 1 since the mobile code and the update number are acquired from the mobile device 50, the electronic key system 1 uses the in-vehicle information among the information necessary for generating the vehicle code. Information to be managed by the device 10 can be reduced.
- registration of information to the portable device 50 may fail due to disconnection of communication between the portable device 50 and the in-vehicle device 10 or mixing of noise. If registration of information in the portable device 50 fails in this manner, the old vehicle code and key number remain in the portable device 50, which may cause a mismatch with the vehicle code newly registered in the in-vehicle device 10.
- the in-vehicle device 10 includes new information regarding the portable device 50 in which the key number is to be registered. Information before registration is retained. As a result, according to the electronic key system 1, the above situation can be prevented and the portable device 50 can function as an electronic key.

〈車載装置〉
車載装置10は、UHF受信部12、LF送信部14、ドアアンテナ16、トランク内アンテナ18、トランク外アンテナ20、室内アンテナ22、エンジン始動機構24、電子制御装置(ECU)32、報知装置38などを備えている。
〈携帯機〉
携帯機50は、それぞれ、LF受信部52、UHF通信部54、プッシュスイッチ56,58、近距離無線通信部60、制御回路62、報知機構68を備えている。
〈電子キーシステムの動作概要〉
このように構成された電子キーシステム1において実行される認証処理について説明する。なお、認証処理は、予め規定された周期で繰り返し実行される。
