　特許文献１には、車両のドアの施錠又は解錠を行う場合に、車載装置が無線端末、例えば、電子キーと無線で通信する通信システムが開示されている。この通信システムでは、車両のドアの施錠又は解錠を行う場合、車載装置は、応答信号の送信を要求する要求信号を無線端末に送信する。無線端末は、要求信号を受信した場合に応答信号を無線で車載装置に送信する。車載装置が応答信号を受信した場合、車両のドアの施錠又は解錠が行われる。 Patent Document 1 discloses a communication system in which an on-vehicle device communicates wirelessly with a wireless terminal, for example, an electronic key, when locking or unlocking a door of a vehicle. In this communication system, when locking or unlocking the door of the vehicle, the in-vehicle device transmits a request signal requesting transmission of a response signal to the wireless terminal. The wireless terminal wirelessly transmits the response signal to the in-vehicle apparatus when the request signal is received. When the in-vehicle device receives the response signal, locking or unlocking of the door of the vehicle is performed.
　特許文献１に記載の通信システムでは、無線端末が車両内にある状態で車両のドアが施錠している場合であっても、車両外にいる人物が車両のドアを解錠することができる。ドアが施錠されている車両内に無線端末があると仮定する。この場合において、車両の乗員が、例えば幼児のみであり、ドアを解錠する操作を知らないとき、車両外にいる人物がドアを解錠しなければならない。 In the communication system described in Patent Document 1, even when the door of the vehicle is locked while the wireless terminal is in the vehicle, a person outside the vehicle can unlock the door of the vehicle. Suppose that there is a wireless terminal in the vehicle where the door is locked. In this case, when the vehicle occupant is, for example, only an infant and does not know the operation of unlocking the door, a person outside the vehicle must unlock the door.
　特許文献１に記載の通信システムでは、車両外にいる人物は、第２の無線端末、例えば、スマートフォンを操作し、第２の無線端末にトリガ信号を車載装置へ送信させる。トリガ信号には、トリガ信号の送信元を示す認証情報が含まれている。 In the communication system described in Patent Document 1, a person outside the vehicle operates a second wireless terminal, for example, a smartphone, and causes the second wireless terminal to transmit a trigger signal to the on-vehicle apparatus. The trigger signal includes authentication information indicating a transmission source of the trigger signal.
　車載装置は、トリガ信号を受信した場合、受信したトリガ信号に含まれる認証情報が、自身に記憶されている記憶情報と一致するか否かを判定する。車載装置は、認証情報が記憶情報と一致すると判定した場合、無線端末と通信し、無線端末が車両内にあるか否かを判定する。車載装置は、無線端末が車両内にあると判定した場合、第２の無線端末の位置が所定範囲内の位置であるか否かを判定する。車載装置によって、第２の無線端末の位置が所定範囲内の位置であると判定された場合、車両のドアが解錠される。 When the in-vehicle device receives the trigger signal, the in-vehicle device determines whether the authentication information included in the received trigger signal matches the storage information stored in the device. When it is determined that the authentication information matches the stored information, the in-vehicle device communicates with the wireless terminal and determines whether the wireless terminal is in the vehicle. When it is determined that the wireless terminal is in the vehicle, the in-vehicle device determines whether the position of the second wireless terminal is within the predetermined range. If it is determined by the in-vehicle device that the position of the second wireless terminal is within the predetermined range, the door of the vehicle is unlocked.

　実施形態４における通信システム１では、車両２００外にいる人物は、第１音声を発することによって、第１無線端末３の制御部７６に解錠信号送信処理を実行させる。その後、車両２００外にいる人物は、第２所定音声を発する。これにより、第１無線端末３は解錠信号を車載装置２ａに送信し、複数のドア２ｄ，２ｄ，・・・が解錠される。従って、ドア２ｄの解錠用として予め決められた専用端末を用いる必要はない。 In the communication system 1 in the fourth embodiment, a person outside the vehicle 200 causes the control unit 76 of the first wireless terminal 3 to execute an unlock signal transmission process by emitting a first voice. Thereafter, the person outside the vehicle 200 emits a second predetermined sound. Thereby, the first wireless terminal 3 transmits an unlocking signal to the in-vehicle device 2a, and the plurality of doors 2d, 2d,... Are unlocked. Therefore, it is not necessary to use a dedicated terminal predetermined for unlocking the door 2d.
