Each part is controlled, such as performing. The CPU 30 that executes the program constitutes display means in the present invention.

  The operation of the arrival information notification system 1 configured as described above will be described with reference to FIGS.

  FIG. 4 is a flowchart for explaining the operation of the arrival information notification system 1. In FIG. 4, the flow in the first column shows the operation of the in-vehicle device 3, and the flow in the second column shows the operation of the information display device 5. A broken arrow indicates a flow of information transmitted and received between the in-vehicle device 3 and the information display device 5.

  In FIG. 4, 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 information display device 5 (S4).

  Here, as shown in FIG. 5, 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.

  The CPU 10 does not wait for an input to notify the estimated arrival time, and calculates the arrival information set to the information display device 5 when the destination is set and the estimated arrival time is calculated. You may make it transmit.

  In FIG. 4, in the information display device 5 that has received the travel information, the CPU 30 starts the travel information display program stored in the hard disk 33 or the like (S5). Here, when the information display device 5 is activated, the CPU 30 activates a program that waits for reception of the travel information. When the travel information is received, the CPU 30 activates the travel information display program and sounds a notification sound. The user of the information display device 5 is notified of the reception of the travel information.

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 makes an information acquisition request for requesting travel information to the in-vehicle device 3 that is the transmission source of the travel information via the communication module 36 (S6).

  In the in-vehicle device 3 that has transmitted the travel information in step S4, the CPU 10 calculates the current position (S7) and the estimated arrival time (S8) at predetermined time intervals. During this time, the CPU 10 determines whether or not the current position has reached the destination (S9). If it is determined that the current position has reached the destination, the travel information with the arrival notification mode set to OFF is displayed. It transmits to the information display apparatus 5 via the communication module 16 (S10).
