  The process in which map information is memorize | stored in the map information storage part 23 is not ask | required. For example, the map information may be stored in the map information storage unit 23 via a recording medium, and the map information transmitted via a communication line or the like is stored in the map information storage unit 23. May be. For example, the receiving unit 21 of the terminal device 20 may also receive map information from the vehicle device 10 and store it in the map information storage unit 23. In this case, the transmission unit 12 of the vehicle apparatus 10 reads out map information in the vicinity of the current position of the vehicle 1 from a map information storage unit (not shown) included in the navigation apparatus and transmits the map information to the terminal device 20.

  The display unit 24 reads out map information corresponding to the current position included in the vehicle information accumulated by the output unit 22 from the map information storage unit 23 and displays the map information. That is, the display unit 24 reads out map information corresponding to the current position included in the vehicle information from the map information storage unit 23 and displays it. In the case of the display, the display part 24 shall read and display only the map information of the area | region used as a display object from the map information storage part 23. FIG.

  Further, when communicating with the vehicle apparatus 10, the terminal apparatus 20 may transmit information such as an address and authentication necessary for establishing the communication. Therefore, the terminal device 20 may include a transmission unit (not shown) that transmits information necessary for controlling such communication.

Next, the operation of the vehicle apparatus 10 according to the present embodiment will be described using the flowchart of FIG.
(Step S101) The acquisition unit 11 acquires vehicle information. The acquired vehicle information may be temporarily stored in a recording medium (not shown). In this embodiment, it is assumed that the vehicle information includes at least the current position.

  (Step S102) The transmission unit 12 determines whether or not to transmit vehicle information. And when transmitting, it progresses to step S103, and when not transmitting, it returns to step S101. The transmission unit 12 holds the vehicle information transmitted last on a recording medium (not shown), and the vehicle information acquired by the acquisition unit 11 matches the vehicle information transmitted last on the recording medium. If so, it may be determined not to transmit, and if they do not match, it may be determined to transmit. By doing in this way, the same vehicle information is not transmitted continuously. Here, when a plurality of information is included in the vehicle information, the transmission unit 12 does not match the vehicle information when at least one information included in the vehicle information does not match in the determination of the match. You may judge.

  (Step S <b> 103) The transmission unit 12 wirelessly transmits the vehicle information acquired by the acquisition unit 11 to the terminal device 20. When there are a plurality of terminal devices 20, the transmission unit 12 may wirelessly transmit the vehicle information to each of the plurality of terminal devices 20. Then, the process returns to step S101.

  In the flowchart of FIG. 4, the process ends when the power is turned off or the process ends. In the flowchart of FIG. 4, all the acquired vehicle information may be wirelessly transmitted to the terminal device 20 without performing the determination in step S102. In the flowchart of FIG. 4, the acquisition unit 11 may acquire the vehicle information by determining that the vehicle information is acquired at regular intervals (for example, every 5 seconds or every 10 seconds).

  Moreover, it is preferable that the vehicle information that the vehicle device 10 transmits to the terminal device 20 by wireless communication is the latest information. Therefore, in the acquisition and transmission processing of vehicle information, it is preferable that the processing from acquisition of the vehicle information to transmission is performed in a short time.

Next, the operation of the terminal device 20 according to the present embodiment will be described using the flowchart of FIG.
(Step S201) The receiving unit 21 determines whether vehicle information wirelessly transmitted from the vehicle apparatus 10 has been received. If received, the process proceeds to step S202. If not, the process of step S201 is repeated until received.

  (Step S202) The output unit 22 outputs the vehicle information received by the receiving unit 21. In the present embodiment, as described above, the output unit 22 accumulates the vehicle information received by the receiving unit 21 in the recording medium.

  (Step S203) The display unit 24 reads out map information corresponding to the current position included in the vehicle information accumulated by the output unit 22 from the map information storage unit 23 and displays the map information. Then, the process returns to step S201. The display unit 24 may display a mark or the like indicating the current position in the map information to be displayed. Further, when the route is being guided, the display unit 24 may display a guide such as “turn right at the next intersection”. In the case of a navigation device that outputs the guide sound, the terminal device 20 may include a guide sound output unit (not shown) that generates sound of the guide and outputs the sound to a speaker. Further, when the vehicle information includes information other than the current position, the display unit 24 may also display the information.

  In the flowchart of FIG. 5, the process ends when the power is turned off or the process ends. Further, when there is no change in the current position received by the receiving unit 21 and included in the vehicle information accumulated by the output unit 22 (that is, the current position accumulated before and the newly accumulated current position are the same) ), The map corresponding to the current position need not be displayed in step S203. That is, you may make it display continuously the same thing as the map currently displayed. Even in this case, if there is a change in information other than the current position included in the vehicle information, only the display of the information may be updated.

  Next, the operation of the information communication system according to the present embodiment will be described using a specific example. In this specific example, the vehicle 1 is assumed to be an automobile equipped with a car navigation device.

  Assume that the user of the rear seat inputs an instruction to display a map of the current position by operating the terminal device 20 which is a PDA while the automobile is traveling. Then, the terminal device 20 accesses the vehicle device 10 by wireless communication, and registers the terminal device 20 as a transmission destination of vehicle information.

  Thereafter, it is assumed that the acquisition unit 11 of the vehicle apparatus 10 acquires new vehicle information (step S101). The vehicle information includes the latitude / longitude (X101, Y101) as the current position, the speed (40 / km / h) of the automobile (vehicle 1), and the engine speed “2.5” (× 1000 rpm). Suppose that The acquisition unit 11 accumulates the acquired vehicle information in a recording medium (not shown), and passes to the transmission unit 12 that new vehicle information has been acquired. Then, the transmission part 12 compares those acquired vehicle information with the vehicle information acquired last time. In this case, it is assumed that the current position has changed. Then, the transmission unit 12 determines to transmit the vehicle information (step S102), and transmits the vehicle information to the terminal device 20 (step S103). Then, the transmission unit 12 deletes the latest vehicle information from the recording medium (not shown) so that only the latest vehicle information is stored in the recording medium (not shown).

  The vehicle information wirelessly transmitted from the vehicle device 10 is received by the receiving unit 21 of the terminal device 20 and passed to the output unit 22 (step S201). Then, the output unit 22 accumulates the vehicle information on a recording medium (not shown), and notifies the display unit 24 that new vehicle information has been accumulated (step S202). When the display unit 24 receives that the new vehicle information has been accumulated, the display unit 24 reads the newly accumulated vehicle information, and displays the map information corresponding to the current position (X101, Y101) included therein in the map information storage unit 23. Read from. Then, the map information, the triangular mark indicating the current position, the hourly speed of the automobile (vehicle 1) and the engine speed are displayed on the display screen of the terminal device 20 (step S203). As a result, a display as shown in FIG. 6 is made. In FIG. 6, the display screen of the terminal device 20 displays a map, a triangular mark indicating the current position, “40 km / h” per hour, and an engine speed “2.5 × 1000 rpm”. . The user of the terminal device 20 can know an accurate current position by viewing the display. In addition, it is possible to know the speed per hour and the engine speed while in the rear seat.

  As described above, according to the information communication system according to the present embodiment, vehicle information that is information related to the vehicle 1 can be provided to the terminal device 20 in real time by wireless communication. As a result, for example, the current position can be acquired more accurately than when the current position is acquired using the GPS function or the like of the terminal device 20, and a map corresponding to the current position can be displayed. become able to. Further, the terminal device 20 can also know information on the speed and engine that cannot be known from other than the driver's seat.

  Further, the terminal device 20 according to the present embodiment can be used as a navigation device as described above, for example. Further, when the vehicle 1 is an automobile or the like, the speed of the automobile or the like can be known, and therefore, it can be used in the lesson of the automobile or the like. For example, in a lesson such as a car, an instructor sitting in a passenger seat or a rear seat can use the terminal device 20 to know the driving situation of a student.

  Note that the terminal device 20 may include a current position acquisition unit that acquires the current position (as described above, for example, GPS may be used). And according to the current position acquired by the current position acquisition unit, the display unit 24 may read and display the map information stored in the map information storage unit 23. Even in such a case, when the terminal device 20 comes to be located at a position where the terminal device 20 can wirelessly communicate with the vehicle device 10, for example, inside the vehicle 1, the display unit 24 is transmitted from the vehicle device 10, You may make it display a map using the present position contained in the vehicle information which the receiving part 21 received and the output part 22 accumulate | stored. Therefore, the terminal device 20 may include a selection unit (not shown) that selects one of the current position acquired by the current position acquisition unit and the current position included in the vehicle information received from the vehicle device 10. The selection unit (not shown) selects the current position included in the vehicle information received from the vehicle device 10 when wireless communication with the vehicle device 10 is possible, and when the wireless communication with the vehicle device 10 is not possible, The current position acquired by the current position acquisition unit of the device 20 is selected. And the display part 24 shall read and display the map information according to the present position which the selection part selected. In this way, the terminal device 20 obtains the current position from a current position acquisition unit (not shown) and the vehicle information received from the vehicle device 10 and accumulated by the output unit 22 when wireless communication is possible with the vehicle device 10. And a selection unit (not shown) that selects the current position acquired by the current position acquisition unit of the terminal device 20 when the current position included in the terminal device 20 is not wirelessly communicable with the vehicle apparatus 10. May display map information using the current position selected by the selection unit. Here, for example, the selection unit may determine that wireless communication with the vehicle device 10 is possible when the vehicle device 10 enters the communication range, and the wireless communication with the vehicle device 10 can be established. In addition, it may be determined that wireless communication with the vehicle apparatus 10 is possible. Even in the former case, when entering the communication range, wireless communication between the terminal device 20 and the vehicle device 10 is immediately established, and the terminal device 20 receives vehicle information from the vehicle device 10. Shall be.

  In the present embodiment, the vehicle information includes the current position, and the terminal device 20 mainly displays the map information using the current position. However, this need not be the case. That is, the terminal device 20 may not display the map information corresponding to the current position. In that case, the terminal device 20 may not include the map information storage unit 23 and the display unit 24. When the terminal device 20 does not include the map information storage unit 23 or the like, the terminal device 20 may output the vehicle information received by the receiving unit 21 through the output unit 22. In this case, it is preferable that the output is usually an output that shows the vehicle information to the user. That is, the output may be display, audio output, printing, or the like, as described above.

  In addition, some examples of the vehicle information have been given, but the vehicle information is not limited to them, and may be other information as long as the information changes while the vehicle 1 is moving. Needless to say.
