  FIG. 3 is a flowchart showing a processing procedure related to pairing of the mobile communication device 1. Here, a pairing procedure between the first mobile communication device 1 and the second mobile communication device 1 will be described. The control unit 11 of the first mobile communication device 1 receives a pairing start operation at the reception unit 14 (step S11) and transmits pairing registration request information to the second mobile communication device 1 (step S12). ). For example, the control unit 11 receives a pairing start operation at the reception unit 14 and displays a list of vehicles C within the communication range of the wireless communication unit 16 and capable of inter-vehicle communication on the display unit 13. When the identifier, the vehicle type, and the user name of each vehicle C are transmitted / received by inter-vehicle communication, the vehicle type and the user name of each vehicle C are displayed. And a user performs selection operation of the vehicle C which desires pairing. The control unit 11 receives the selected vehicle C at the reception unit 14. When the pairing target vehicle C is selected, the control unit 11 transmits registration request information to the mobile communication device 1 mounted on the vehicle C. The registration request information is information indicating that pairing is requested, and includes its own identifier, the model of the vehicle C on which it is mounted, the user name, and the like.

The pairing registration request may be indicated by a certain combination of data that is constantly transmitted and received by inter-vehicle communication, such as a direction indicator, a wiper, and a brake. That is, by using a combination of data that cannot be a normal operation as data indicating a pairing registration request, it is possible to request pairing registration from another vehicle C without using an additional communication frame. it can. In the pairing registration request, it is not necessary to actually operate the direction indicator or the like.
The pairing registration request operation may be configured to be received by a predetermined operation by the user, for example, a predetermined operation on the receiving unit 14, or configured to be received by a certain operation such as a direction indicator, a wiper, or a brake. You may do it.

  When the second mobile communication device 1 receives pairing registration request information at the wireless communication unit 16 (step S13), the second mobile communication device 1 registers pairing based on the vehicle type and user name information included in the registration request information. The requesting vehicle type and user name are displayed on the display unit 13 (step S14). And the control part 11 determines whether the permission of pairing was received in the reception part 14 (step S15). When the permission of pairing is received (step S15: YES), the control unit 11 stores the identifier, vehicle type, and user name of the mobile communication device 1 that is the request source of pairing in the storage unit 12 (step S16), and follows The mode shifts to the movement support mode (step S17). And the control part 11 transmits the registration permission information which showed that registration of pairing is permitted to the 1st mobile communication apparatus 1 in the radio | wireless communication part 16 (step S18).

  The control unit 11 of the first mobile communication device 1 receives the registration permission information transmitted from the second mobile communication device 1 (step S19), and the second mobile communication device 1 that is the pairing request destination. The identifier, vehicle type, and user name are stored in the storage unit 12 (step S20). And the control part 11 transfers to following movement assistance mode (step S21), and complete | finishes a process.

  When the rejection of pairing is accepted in step S15 (step S15: NO), the control unit 11 transmits the rejection information for refusing registration of pairing to the first mobile communication device 1 by the wireless communication unit 16. (Step S22).

  The control unit 11 of the first mobile communication device 1 receives the rejection information transmitted from the second mobile communication device 1 (step S23), displays the rejection information on the display unit 13 (step S24), Finish the process.

  Thereafter, the mobile communication device 1 identifies the paired vehicle C using the identifier stored by the pairing registration.

The mobile communication device 1 communicates with the counterpart mobile communication device 1 registered for pairing, such as when the counterpart mobile communication device 1 is outside the wireless communication range or when the counterpart mobile communication device 1 is powered off. If the inability to continue continues for a certain period of time, cancel pairing registration.
After the pairing registration is canceled, it is preferable that the mobile communication device 1 that has been previously paired and registered again is configured to automatically perform pairing registration when the vehicle-to-vehicle communication becomes possible. For example, when the communication time has not passed since a predetermined time has elapsed and the identifier, the vehicle type, and the user name of the mobile communication device 1 of the communication partner are the same as the contents previously registered for pairing, What is necessary is just to perform pairing registration automatically. When a predetermined time or more has passed since the communication was interrupted, it is preferable to ask the user to confirm the pairing registration before executing the pairing registration, and perform the pairing registration after accepting the user's confirmation operation.

  In addition, when one mobile communication device 1 cancels pairing registration by a user's operation, it may be configured to notify other mobile communication devices 1 to that effect.
