[Remote control method of vehicle]
As described above, in this embodiment, when the vehicle 3 is locked, the user needs to touch the vehicle 3 with the mobile phone 1. Therefore, if the user leaves the vehicle 3 without touching the mobile phone 1 with the vehicle 3, the vehicle 3 remains unlocked. Therefore, in this embodiment, in such a case, the vehicle 3 is automatically locked by remote control. Hereinafter, the remote control method at this time will be described based on the flowchart shown in FIG.

As described above, when NFC communication is performed between the mobile phone 1 and the ticket gate 2 (steps S101 and S102), that is, when the mobile phone 1 is used as an electronic wallet, the user moves from the vehicle 3. It can be judged that it is separated. Therefore, when the billing server 4 receives the ID code of the mobile phone 1 together with the billing data from the gate data communication device 22 (steps S103 and S104), the billing server 4 immediately transmits the ID code to the vehicle management server 5 (step S105). In addition, when NFC communication is performed between an external device other than the ticket gate 2 and the mobile phone 1, it can be determined that the user is away from the vehicle 3 in the same manner. Therefore, the accounting server that has received the ID code of the mobile phone 1 from the external device transmits the ID code to the vehicle management server 5.

  Locking / unlocking data is transmitted from the in-vehicle data communication device 34 to the vehicle management server 5 (steps S111 and S112). When the vehicle management server 5 receives the ID code of the mobile phone 1 transmitted from the billing server 4 (step S106), it determines whether or not the vehicle 3 is locked based on the unlocking data (step S106). S107). When it determines with the vehicle 3 not being locked, the vehicle management server 5 transmits a locking signal to the vehicle-mounted data communication apparatus 34 of the vehicle 3 (step S108).

  When receiving the locking signal transmitted from the vehicle management server 5 (step S109), the in-vehicle data communication device 34 inputs the locking signal to the lock control unit 331 of the ECU 33. When the lock signal is input, the lock control unit 331 locks the vehicle 3 (step S110).

  According to such remote control, the vehicle 3 can be locked automatically even when the user has left the vehicle 3 without locking.

[Other remote controls]
There may be a case where the user leaves the vehicle 3 without stopping the engine (ignition OFF) as well as locking the vehicle 3. Therefore, in this embodiment, the engine may be stopped together with locking of the vehicle 3 by remote control.

  Hereinafter, the remote control method at this time will be described based on the flowchart shown in FIG. Even in this case, the control flow in (a) the mobile phone, (b) the ticket gate (external device), and (c) the billing server is the same as the flow shown in FIG. Moreover, the process of step S106-112 in the control flow in (d) vehicle management server and (e) vehicle is the same as the flow shown in FIG.

  IG-ON / OFF data is transmitted from the vehicle-mounted data communication device 34 to the vehicle management server 5 (steps S215 and S216). When the vehicle management server 5 receives the ID code of the mobile phone 1 transmitted from the billing server 4 (step S106), it determines whether or not the vehicle 3 is locked (step S107) and the IG− Based on the ON / OFF data, it is determined whether or not the ignition of the vehicle 3 is OFF (step S211). When it is determined that the ignition of the vehicle 3 is not OFF, the vehicle management server 5 transmits an ignition OFF (IG-OFF) signal to the in-vehicle data communication device 34 of the vehicle 3 (step S212).

  When receiving the IG-OFF signal transmitted from the vehicle management server 5 (step S213), the in-vehicle data communication device 34 inputs the IG-OFF signal to the IG control unit 332 of the ECU 33. When the IG-OFF signal is input, the IG control unit 332 turns off the ignition of the vehicle 3 (step S214). Thereby, the engine of the vehicle 3 is stopped.

  According to such remote control, even when the user leaves the vehicle 3 without stopping the engine, the engine can be automatically stopped.

<Example 2>
[Remote control method of vehicle]
The vehicle remote control system according to the present embodiment is the same as that of the first embodiment in that the vehicle 3 is automatically locked when the user is away from the vehicle 3. However, even when the user is away from the vehicle 3, the distance between the user and the vehicle 3 may be relatively short, and the necessity of locking the vehicle 3 may be low (for example, installed on the side of the road). For example, when purchasing products with a vending machine. Therefore, in this embodiment, when NFC communication is performed between the external device and the mobile phone 1, the distance between the mobile phone 1 and the vehicle 3 (that is, the distance between the user and the vehicle 3) is more than a predetermined distance. Only when this is the case, the vehicle 3 is automatically locked by remote control. Here, the predetermined distance is a distance set as the maximum value of the distance considered that the necessity of locking the vehicle is low.

  Hereinafter, the remote control method at this time will be described based on the flowchart shown in FIG. Even in this case, the control flow in (a) the mobile phone and (b) the ticket gate (external device) is the same as the flow shown in FIG. Moreover, the process of step S107-112 in the control flow in (d) vehicle management server and (e) vehicle is also the same as the flow shown in FIG.

  When NFC communication is performed between the mobile phone 1 and an external device such as the ticket gate 2, the position of the external device can be handled as the location of the mobile phone 1 (that is, the user's location). Thus, in this embodiment, the external device transmits the location data of the external device to the accounting server 4 together with the accounting data and the ID code of the mobile phone 1.

  When the charging server 4 receives the charging data, the ID code of the mobile phone 1 and the position data of the external device from the external device (step S304), the charging server 4 immediately sends the ID code and the position data of the external device to the vehicle management server 5. Transmit (step S305).

  Position data of the vehicle 3 acquired by the car navigation device of the vehicle 3 is transmitted from the in-vehicle data communication device 34 to the vehicle management server 5 (steps S309 and S310). When the vehicle management server 5 receives the ID code of the mobile phone 1 and the position data of the external device transmitted from the billing server 4 (step S306), the vehicle management server 5 is based on the position data of the vehicle 3 and the position data of the external device. The distance between the vehicle 3 and the external device (that is, the distance between the vehicle 3 and the mobile phone 1) ΔLdv is calculated.

  Next, the vehicle management server 5 determines whether or not the calculated distance ΔLdv is longer than the predetermined distance ΔL0. Here, when it is determined that the distance ΔLdv is longer than the predetermined distance ΔL0, the vehicle management server 5 determines whether the vehicle 3 is locked as in the first embodiment (step S107). On the other hand, when it is determined that the distance ΔLdv is equal to or less than the predetermined distance ΔL0, the vehicle management server 5 ends the execution of this flow without confirming the locked / unlocked state of the vehicle 3.

  According to such remote control, it is possible to automatically lock the vehicle 3 only when the user is away from the vehicle 3 without locking and there is a high necessity for locking. .

  Even when the ignition of the vehicle 3 is automatically turned off when the user is away from the vehicle 3, as in the above, only when the distance between the vehicle 3 and the external device is longer than a predetermined distance, The ignition may be turned off. According to this, the ignition can be turned off only when the necessity is high.
