Can be configured. Thereby, a keyless entry system can be realized without preparing a wireless device dedicated to the keyless entry system. In other words, the inter-terminal communication system 1 can improve the convenience of functions provided by communication between the terminal device and the in-vehicle device.

Further, when the vehicle 2 includes a car navigation system, the smartphone 10 can be configured as a map image display device instead of the map image display device dedicated to the car navigation system. In this case, since the map image is displayed on the smartphone 10, for example, the map image can be seen also in the rear seat of the vehicle 2. In other words, the inter-terminal communication system 1 can improve the convenience of functions provided by communication between the terminal device and the in-vehicle device.

In addition, the information transmitted / received between the terminal device 10 and the vehicle-mounted apparatus 20 is not restricted to what was mentioned above. For example, the terminal device 10 may acquire charge payment information from an ETC (Electronic Toll Collection System) vehicle-mounted device and display an image based on the acquired charge payment information on the display unit 105.

In addition, although the case where the terminal device 10 was a smart phone was demonstrated as an example until now, it is not restricted to this. For example, the terminal device 10 may be a tablet terminal (not shown).
Here, the size of the display unit 105 (liquid crystal display) of the smartphone 10 is about 3 to 5 types, whereas the size of the liquid crystal display of the tablet terminal is about 7 to 10 types.
Therefore, when the terminal device 10 is a tablet terminal, the visibility of the displayed image can be improved compared to the case where the terminal device 10 is a smartphone. Moreover, since the tablet terminal has a larger size of the operation detection unit 106 (touch panel) than a smartphone, the operability can be improved.

In addition, you may make it implement | achieve a part of the terminal device 10 in the embodiment mentioned above, or the vehicle-mounted apparatus 20 with a computer. In that case, the program for realizing the control function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read by the computer system and executed. The “computer system” here is a computer system built in the terminal device 10 or the in-vehicle device 20 and includes hardware such as an OS and peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” is a medium that dynamically holds a program for a short time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line, In this case, a volatile memory inside a computer system that serves as a server or a client may be included that holds a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. Moreover, you may implement | achieve part or all of the terminal device 10 in the embodiment mentioned above, or the vehicle equipment 20 as integrated circuits, such as LSI (Large Scale Integration). Each functional block of the terminal device 10 or the in-vehicle device 20 may be individually made into a processor, or a part or all of them may be integrated into a processor. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. In addition, when an integrated circuit technology that replaces LSI appears due to the advancement of semiconductor technology, an integrated circuit based on the technology may be used.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
