  In FIG. 6, first, in the in-vehicle device 3, the CPU 10 determines the current position based on the latitude and longitude measured by the GPS receiver 17, the traveling direction detected by the gyro 18 and the vehicle speed detected by the vehicle speed sensor 19. Calculate (S1).

  Here, when a destination is set by the user of the in-vehicle device 3 via the input device 15 (S2), the CPU 10 searches for a route from the current position to the destination, and calculates the expected arrival time of the destination. Calculate (S3).

  Next, when the user of the in-vehicle device 3 inputs that the expected arrival time is notified to the queuing partner via the input device 15, the CPU 10 transmits the travel information in which the arrival notification mode is set to ON to the communication module 16. Is transmitted to the center device 4 via S4 (S4).

  Here, as shown in FIG. 7, the traveling information includes information representing the user ID, the destination, the current position, and the estimated arrival time in addition to the arrival notification mode.

  Note that the CPU 10 does not wait for an input to notify the estimated arrival time, and transmits the traveling information in which the arrival notification mode is turned on to the center device 4 when the estimated destination time is set and the estimated arrival time is calculated. You may make it do.

  In FIG. 6, in the center device 4 that has received the travel information, the CPU 20 authenticates the user of the in-vehicle device 3 based on the user ID and the like included in the received travel information (S5). When the user of the in-vehicle device 3 is authenticated, the CPU 20 stores the travel information in the hard disk 23 in association with the user ID of the in-vehicle device 3 and also notifies the destination based on the correspondence table stored in the hard disk 23. The information display device 5 is identified (S6).

  When the information display device 5 is specified, the CPU 20 transmits initial information to the specified information display device 5 via the communication module 24 (S7). Here, as shown in FIG. 8, the initial information includes information indicating a user ID, an arrival notification mode, and an address indicating a request destination of travel information such as a URL (Uniform Resource Locator). .

  In the information display device 5 that has received the initial information, the CPU 30 activates the travel information display program stored in the hard disk 33 or the like (S8).

The user of the information display device 5 is notified of the reception of the initial information.

  Instead of starting the driving information display program in response to receiving the initial information, the CPU 30 sounds a notification sound and prompts the user of the information display device 5 to start the driving information display program on the display 34. And the travel information display program may be activated in response to an input via the input device 35.

  Next, the CPU 30 that executes the travel information display program acquires the access destination that is the request destination of the travel information from the initial information (S9), and sends an information acquisition request that requests the travel information to the acquired access destination. 36 (S10). The access destination in the present embodiment is the center device 4.

  In the in-vehicle device 3 that has transmitted the travel information in step S4, the CPU 10 calculates the current position (S11) and the predicted arrival time (S12) at predetermined time intervals. During this time, the CPU 10 determines whether or not the current position has reached the destination (S13). If the CPU 10 determines that the current position has reached the destination, the travel information with the arrival notification mode set to OFF is displayed.

It only has to be done. For example, since the destination ID is not updated unless changed by the user of the in-vehicle device 3, it may not be set in the information regular update.

  Next, the CPU 20 determines whether or not there has been an information acquisition request from the information display device 5 (S17). If it is determined that there has been an information acquisition request, the CPU 20 sends running information to the information display device 5 that has made the information acquisition request. Is transmitted through the communication module 24 (S18).

  After the CPU 20 determines that there is no information acquisition request, or determines that there is an information acquisition request and makes an information acquisition response, the traveling information with the arrival notification mode set to off is transmitted from the in-vehicle device 3. It is determined whether or not (S19).

  When it is determined that the travel information with the arrival notification mode set to OFF is transmitted from the in-vehicle device 3, the CPU 20 transmits the travel information to the information display device 5 via the communication module 24 (S20).

  On the other hand, when it is determined that the travel information with the arrival notification mode set to OFF is not transmitted from the in-vehicle device 3, the CPU 20 receives the travel information transmitted by the in-vehicle device 3 or from the information display device 5. The information acquisition request is awaited (S16, S17).

  In the information display device 5 that is the information acquisition response destination, the CPU 30 acquires the transmitted travel information (S21), and stores the acquired travel information in the hard disk 33.

  Next, the CPU 30 performs a display data processing process based on the acquired travel information (S22). In this display data processing, the CPU 30 generates map information representing a map of an area including the current position represented by the travel information from the map data stored in the hard disk 33.

  Here, the CPU 30 may generate map information in a vector format that represents a map with a feature object, or may generate map information in a raster format that represents a map with image image data.

  In the display data processing, in addition to the current position represented by the travel information, the CPU 30 obtains the destination, the route from the current position to the destination, and the current position obtained from the travel information history stored in the hard disk 33. You may make it produce | generate the map information to which the additional information showing a driving | running | working locus | trajectory etc. was added.

  Next, the CPU 30 displays the acquired travel information and the generated map information on the display 34 according to the display mode (S24).

  Here, as a display mode to be displayed on the display 34 by the CPU 30, an expected arrival time display mode in which an expected arrival time is displayed on the display 34, and a map of an area including at least the estimated arrival time, the current position, and the current position (hereinafter collectively referred to as a generic name). And a map display mode for displaying “arrival notification content” on the display 34.

  For example, when the information display device 5 is configured by a television, in the expected arrival time display mode, the CPU 30 overlaps with the display area 50 of the program being viewed as shown in FIG. In the map display mode, as shown in FIG. 9B, the display area 50 of the program being viewed is narrowed, and the arrival notification content is displayed in the empty display area 52.

  In the estimated arrival time display mode, the CPU 30 may display the estimated arrival time in a translucent manner. Further, the CPU 30 may display the remaining time until the estimated arrival time instead of the estimated arrival time. The CPU 30 may display the user name of the in-vehicle device 3 on the display 34.

  The display mode is desirably selected by a simple operation such as pressing a button constituting the input device 35 by the user of the information display device 5.

  Further, the CPU 30 may select the display mode according to the remaining time until the estimated arrival time and the distance from the current position of the in-vehicle device 3 to the destination. For example, the CPU 30 may switch the display mode from the predicted arrival time display mode to the map display mode when the remaining time until the estimated arrival time is 5 minutes or less. When the distance from the destination to the destination is 10 km or less, the display mode may be switched from the estimated arrival time display mode to the map display mode.

  Next, the CPU 30 determines whether or not traveling information with the arrival notification mode set to OFF is transmitted from the center device 4 (S25), and traveling information with the arrival notification mode set to OFF is received from the center device 4. If it is determined that it has been transmitted, the execution of the travel information display program is terminated (S26).

  On the other hand, if the CPU 30 determines that the traveling information with the arrival notification mode set to OFF has not been transmitted from the center device 4, the CPU 30 makes a next information acquisition request (S10).

  Note that the CPU 30 may make an information acquisition request at a predetermined time interval or may make a request in response to a user input via the input device 35.

  Since the arrival information notification system 1 according to the embodiment of the present invention can notify the information display device 5 of the latest expected arrival time, the expected arrival time can be confirmed in real time by the waiting party. .

  As described above, the arrival information notification system according to the present invention has an effect that the expected arrival time can be confirmed in real time by the other party. For example, the arrival arrival time of the destination set in the in-vehicle device is determined. This is useful as an arrival information notification system for notifying a device on the other end of the meeting.
