Specifically, when the operation information is received, the control unit (request unit) 10 of the mobile terminal 1 transmits a request signal for the key information 21 a by the short-range wireless communication unit 12. When the control unit 20 of the vehicle key 2 receives the request signal, it reads the key information 21a from the storage unit 21 and transmits it by the short-range wireless communication unit 23, and the control unit 10 of the portable terminal 1 The short distance wireless communication unit 12 receives the information 21a.
At this time, the mobile terminal 1 may determine whether or not the vehicle information received together with the operation information by the mobile terminal 1 is appropriate, or the mobile terminal 1 transmits the vehicle information together with the request signal to the vehicle key 2. However, the determination may be made with the vehicle key 2. When the determination is made by the mobile terminal 1, information (appropriate vehicle information of the vehicle C) for comparison with the received vehicle information is stored in advance in the storage unit 11 of the mobile terminal 1.

  The control unit 10 of the portable terminal 1 transmits (returns) the key information 21a received from the vehicle key 2 to the trunk control device 3 that is the transmission source of the operation information at the network communication unit (transmission unit) 13 (S10). . The key information 21 a transmitted by the network communication unit 13 is received by the wireless communication device 40 in the home building H via the network N and the modem 41, further transferred by the wireless communication device 40, and wirelessly stored in the vehicle C. It is received by the communication device 30. The trunk control device 3 receives the key information 21a at the wireless communication device (reception unit) 30 (S11). Then, the trunk control device (determination unit) 3 determines whether or not the received key information 21a is appropriate (S12). The trunk control device 3 reads the key information stored in its own storage unit, and determines that the received key information 21a is appropriate when the received key information 21a matches the read key information. . When it is determined that the received key information 21a is not appropriate (S12: NO), the trunk control device 3 ends the process without performing anything.

  When it is determined that the received key information 21a is appropriate (S12: YES), the trunk control device 3 (control unit) unlocks the trunk of the vehicle C by the trunk actuator 31 (S13). Note that the trunk control device (determination unit) 3 transmits operation information (information indicating that the trunk open switch 32 has been operated) when determining whether or not the received key information 21a is appropriate. It may be determined whether or not. Only when it is determined that the operation information has been transmitted, the trunk control device 3 may determine whether or not the received key information 21a is appropriate. In such a configuration, the trunk can be unlocked only when the key information 21a transmitted from the vehicle key 2 to the trunk control device 3 after the trunk open switch 32 of the vehicle C is operated is appropriate. Therefore, even when appropriate key information 21a is transmitted from the vehicle key 2 to the trunk control device 3, the trunk is not unlocked unless the trunk open switch 32 is operated. Thereby, it is possible to prevent the trunk from being unlocked by an inappropriate procedure.

  When the trunk of the vehicle C is unlocked, the trunk lid is slightly opened. Therefore, the delivery person manually opens the trunk (trunk lid), puts the luggage into the trunk, and then manually closes the trunk (trunk lid). When the trunk is closed, the trunk is locked by the trunk actuator 31. As a result, it is possible to prevent the loss of the package received at the trunk.

Also in the second embodiment, when the delivery person brings the package to the recipient's home building H and the recipient is out, the package is stored in the trunk of the vehicle C owned by the recipient. Explained as an example. It is assumed that the recipient carries the vehicle key 2 and the portable terminal 1 and the vehicle C is parked near the home building H.
Also in the second embodiment, when the payee is not in the home building H, the delivery person notifies the payee that he / she is currently in front of the home building H of the payee.
The recipient who received the notification tells the delivery person the parking location, the vehicle number and the characteristics of the vehicle C owned by the recipient, and instructs the delivery person to go to the vicinity of the vehicle C. The delivery person waits in the vicinity of the vehicle C according to the instruction from the recipient. Further, the recipient operates the operation unit 14 of the portable terminal 1 so as to be in a state where short-range wireless communication is possible, and operates (presses) the trunk unlock button of the vehicle key 2.

The control unit 20 of the vehicle key 2 determines whether or not the trunk unlock button has been operated by the user according to whether or not a predetermined signal is acquired from the operation unit 22 (trunk unlock button) ( S21). When the trunk unlock button is not operated (S21: NO), that is, when it is determined that the predetermined signal is not acquired from the operation unit 22, the control unit 20 does nothing.
When the trunk unlock button is operated (S21: YES), the control unit 20 reads the key information 21a stored in the storage unit 21, and the read key information 21a and the trunk unlock button are operated. Is transmitted (output) by the short-range wireless communication unit 23 (operation S22).

The control unit 10 of the portable terminal 1 receives the key information 21a and the operation information transmitted from the vehicle key 2 at the short-range wireless communication unit 12 (S23). Also here, by transmitting / receiving the key information 21a by short-range wireless communication, it is possible to prevent the key information 21a from being stolen by another person's portable terminal when transmitting / receiving the key information 21a.
The control unit 10 of the portable terminal 1 transmits the key information 21a and the operation information received from the vehicle key 2 to the trunk control device 3 mounted on the vehicle C owned by the recipient through the network communication unit 13 (S24). ). Note that the portable terminal 1 stores destination information of the trunk control device 3 necessary for transmitting the key information 21a and the operation information in the storage unit 11 in advance, and this destination information is stored in the user (the portable terminal 1). It can be arbitrarily changed by the owner and the owner of the vehicle C). Further, the destination information of the wireless communication device 30 or 40 is used in place of the destination information of the trunk control device 3, and the key information 21a and the operation information are transmitted to the wireless communication device 30 or 40. You may make it transfer to the trunk control apparatus 3. FIG. At this time, the destination information of the wireless communication device 30 or 40 is stored in the storage unit 11 in advance.

  The key information 21a and the operation information transmitted by the network communication unit 13 are received by the wireless communication device 40 in the home building H via the network N and the modem 41, and further transferred by the wireless communication device 40, so that the vehicle C Is received by the wireless communication device 30. The trunk control device 3 receives the key information 21a and the operation information at the wireless communication device 30 (S25). Then, the trunk control device 3 determines whether or not the received key information 21a is appropriate (S26). The trunk control device 3 determines that the received key information 21a is appropriate when the received key information 21a matches the key information stored in advance in its own storage unit. If it is determined that the received key information 21a is not appropriate (S26: NO), the trunk control device 3 ends the process without performing anything.

When it is determined that the received key information 21a is appropriate (S26: YES), the trunk control device 3 unlocks the trunk of the vehicle C by the trunk actuator 31 based on the received operation information (S27).
When the trunk of the vehicle C is unlocked, the trunk lid is slightly opened, and the delivery person manually opens the trunk, puts luggage into the trunk, and then manually closes the trunk. Note that when the trunk is closed, the trunk is locked by the trunk actuator 31, so that loss of the luggage received by the trunk can be prevented.

  Also in the second embodiment, the trunk control device 3 may notify the mobile terminal 1 via the network N that the trunk of the vehicle C is locked by the trunk actuator 31 and then the trunk is locked. Not only that the trunk is in the locked state, but also that the trunk is in the unlocked state may be notified as appropriate. Thereby, the recipient (the owner of the vehicle C) can appropriately grasp the locked / unlocked state of the trunk of the vehicle C.

With the above-described processing, even in the second embodiment, even when the vehicle key 2 associated with the vehicle C is located away from the vehicle C and the vehicle key 2 and the trunk control device 3 cannot communicate directly with each other. The trunk of the vehicle C can be unlocked by operating the trunk unlock button of the vehicle key 2. Therefore, for example, when a delivery person brings a package to the building H, the package can be delivered through the trunk of the vehicle C even if the owner of the building H is absent.
In the second embodiment, since the recipient can unlock the trunk of the vehicle C by operating the trunk unlock button of the vehicle key 2, the delivery person can see that the trunk is unlocked in the vicinity of the vehicle C. Just wait. Therefore, the delivery person only has to open the unlocked trunk, and the operability is good.

Also in the second embodiment, when the user (recipient) of the mobile terminal 1 operates the mobile terminal 1 to be able to perform short-range wireless communication, the key information 21a of the vehicle key 2 can be acquired by the mobile terminal 1. . Therefore, even if the trunk unlock button of the vehicle key 2 is accidentally operated, the key information 21a cannot be obtained from the vehicle key 2 unless the portable terminal 1 is in a state where short-range wireless communication is possible. Leakage of the key information 21a can be prevented.
Further, in the second embodiment, when the recipient presses and holds the trunk unlock button of the vehicle key 2 for a long time (for example, an operation of continuously pressing the trunk unlock button for 2 seconds or more), the key information 21a and the operation information are transferred from the portable terminal 1 to the network N May be transmitted to the trunk control device 3 (wireless communication device 30) via In such a configuration, even if the trunk unlock button of the vehicle key 2 is operated by mistake, the key information 21a is not transmitted from the portable terminal 1 unless it is a long press operation. Leakage can be prevented. Whether or not the trunk unlock button has been pressed for a long time may be determined based on the reception time of a signal (operation information) received by the short-range wireless communication unit 12 by the control unit 10 of the mobile terminal 1. .

Also in the second embodiment, the vehicle key 2 and the trunk control device 3 communicate via the network N to unlock not only the trunk of the vehicle C but also the door, window, etc. of the vehicle C.
