In addition, the control circuit 19 executes a program for visiting visitors in the ROM 17 or the external storage unit 18.

  The operation for greeting a visitor in the communication system having such a configuration will be described below. FIG. 3 schematically shows a communication procedure among the visitor terminal 4, the meeter terminal 5, and the vehicle navigation device 6 in the operation for visiting the visitor. FIG. 4 shows a sequence of operations other than the communication of the visitor terminal 4 and the vehicle navigation device 6 along with these communication procedures in chronological order.

  (A1) First, data for specifying a train on which the visitor 1 boardes for a visit (hereinafter referred to as train information data) is input to the visitor terminal 4. Specifically, the name of the station on which the train is boarded for the visit and the departure date / time data of the train to be boarded (hereinafter referred to as boarding train) 7 are input to the visitor terminal 4. Then, the visitor 1 performs an operation on the visitor terminal 4 to transmit the input data to the destination address of the meeter terminal 5. Upon receiving these operations, the visitor terminal 4 shapes the inputted train information data and the human appearance data of the visitor 1 that has been inputted and stored in advance into transmission data in a predetermined format, A signal including transmission data (corresponding to an example of a human appearance signal and a train information signal) is transmitted to a designated destination address. This transmission is performed using the above-described long-distance wireless data communication function. This transmission corresponds to the procedure A1.

  (A2) Upon receiving the transmission data as a signal, the addressee terminal 5 sends the received transmission data and the data of the destination address of the transmission data (that is, the visitor terminal 4) of the short distance wireless communication. It transmits to the navigation apparatus 6 for vehicles using a data communication function. This transmission corresponds to the procedure A2. The meeter terminal 5 may perform the transmission in the procedure A2 based on the fact that the meeter terminal 5 has entered a position where it can communicate with the vehicle navigation device 6, or the meeter 2 is the meeter. When a predetermined operation is performed on the terminal 5, transmission in the procedure A2 may be performed. In addition, the meeter terminal 5 specifies the information of the destination address of the transmission source included in the signal received by the meeter terminal 5 in the procedure A1 as the destination address of the visitor terminal 4 that transmits in the procedure A2. . This destination address information may be added to the transmission data by the relay device in the communication path in the procedure A1, or the visitor terminal 4 may include it in the transmission data at the time of transmission. Good.

  (A3) When the control circuit 19 of the vehicle navigation apparatus 6 receives the train information data, the person appearance data, and the destination address of the visitor terminal 4 from the meeter terminal 5 by the procedure A2, the program group for the visitor welcome Execute one of these. This process corresponds to procedure A3.

  Then, in the execution of the program, the control circuit 19 records the received person appearance data in the external storage unit 18 and, on the basis of the received train information data and the stored train operation data, Specify the time and departure time. The pick-up station 9 is a station where the visitor 1 gets off the boarding train 7 and waits for the pick-up. The meeting time is the time when the visitor 1 gets off at the meeting station 9. The departure time refers to the time at which the greeter 2 should depart from the greeting vehicle 3 to greet the visitor 1 at the greeting time at the greeting station 9.

  The control circuit 19 identifies the station that is most easily reached from the reference position by the greeted vehicle 3 among the stations where the boarding train 7 stops as the greeting station 9. The stop station where the boarding train 7 stops is specified based on the train operation data. The criteria for determining the ease of arrival are, for example, the straight line distance from the reference position to the stop station, the distance of the shortest route from the reference position to the stop station, the time required for traveling on the shortest route from the reference position to the stop station, etc. Is used. In addition, the route from the reference position to the stop station is specified by the above-described guidance route calculation process. The time taken to travel the route is determined based on the length of the route and the expected traveling speed of the route. The expected traveling speed of the route may be a fixed value (for example, 30 kilometer per hour) or may be specified so that the wider the width of the road, the faster the speed of each road on the route. In addition, the VICS receiver 10 may be used to specify for each road on the route so that the road congestion received from the VICS receiver 10 increases as the degree of congestion increases. Further, the congestion degree information may be acquired from a traffic information center on a wide area network by a long-distance data communication mediating function using the meeter terminal 5.

  Further, as the reference position, for example, the current position of the welcome vehicle 3 specified by the above-described current position specifying process, and the home of the meeter terminal 5 recorded in the external storage unit 18 based on the user's operation on the operation unit 13 in advance. There are position etc. The reference position may change based on the operation time of the boarding train 7 specified based on the received train information data. For example, if the operating time of the boarding train 7 (for example, the boarding time of the visitor 1 and the time of getting off) is more than a threshold time (for example, 8 hours) after the current time, the reference position is set to home and within the threshold time If it comes, the reference position is set as the current position of the greeted vehicle 3.

  Note that the control circuit 19 may transmit the specified meeting station 9 and the meeting time to the visitor terminal 4 using the long-distance data communication mediating function of the meeter terminal 5. Thereby, the visitor 1 can confirm clearly which station should get off.

  Moreover, the control circuit 19 reads the stop time of the boarding train 7 in the specified pick-up station 9 based on the train operation data, and specifies the read stop time as the pick-up time. Further, the control circuit 19 calculates the route from the reference position to the meeting station 9 by the guidance route calculation process, and calculates the time for traveling on the calculated route (hereinafter referred to as the “greeting travel time”) as the above-mentioned travel time calculation. In the same manner, a time that is earlier than the specified pick-up time by the pick-up travel time is specified as a start time from the reference position (corresponding to the start position).

  (A4) After that, the navigation device sets a time (hereinafter referred to as notification time) that is back by a margin time (for example, a time between 0 minutes and 30 minutes) from the departure time calculated in step A3. Waiting based on the current time information received by the GPS receiver, and when the notification time arrives, immediately after that, a notification for prompting departure is made to the meeter terminal 5. Specifically, a predetermined notification signal is transmitted to the meeter terminal 5 using the short-range wireless data communication function. Note that departure information may be included in this notification signal. This corresponds to procedure A4. Upon receiving this predetermined notification signal, the meeter terminal 5 prompts the meeter 2 to leave by vibration, sound, image display, or the like. Thus, the meeter 2 can roughly know the departure time. Moreover, it can prevent that the meeter 2 forgets to meet.

  When the short-range wireless communication is realized by Bluetooth, if the distance between the vehicle navigation device 6 and the meeter terminal 5 is within several tens of meters, the meeter terminal 5 can receive a notification by the procedure A4. As a typical example of such a case, there is a case where the greeter 2 is in the home 8 together with the greeter terminal 5 and the greeting vehicle 3 is placed in the garage of the greeter home 8.

  (A5) In response to this notification, when the greeter 2 departs the greeting vehicle 3 to the greeting station 9, the control circuit 19 performs guidance route calculation processing with the greeting station 9 as the destination, and further on the guidance route. Route guidance processing according to the driving situation is performed. This corresponds to procedure A5.

  (A6) When the control circuit 19 detects that the pickup vehicle 3 has arrived at the pickup station 9 (or the vicinity thereof) by the current position specifying process, the control circuit 19 immediately reads the human appearance data recorded in the procedure A3 and displays the read data as an image. Or it displays on the image display apparatus 12 as a character. This corresponds to procedure A6. As a result, the meeter 2 can search for the visitor 1 by relying on the appearance of the displayed visitor 1. In addition, as a display format of the human appearance data, as illustrated in FIG. 5, the face photograph of the visitor 1 and the appearance features of the height, clothes, and belongings are simultaneously displayed on one screen. Also good.

  (A7) Subsequent to step A6, the control circuit 19 uses the long-distance data communication intermediary function of the greeter 2 to obtain the current position data of the greeting vehicle 3 and the vehicle appearance data of the greeting vehicle 3 as a visitor terminal. 4 is transmitted as a signal (corresponding to an example of a vehicle appearance signal). This corresponds to procedure A7. The destination address of the visitor terminal 4 is the one received from the meeter terminal 5 in the procedure A2. Moreover, what is memorize | stored in the external memory | storage part 18 is used for vehicle external appearance data. The current position data is transmitted in a format that can indicate the positional relationship between the current position and the meeting station 9. For example, as shown in FIG. 6, a map image including the meeting station 9 and the current position 31 in the vicinity thereof may be transmitted.

  (A8) The visitor terminal 4 having received such current position data and vehicle appearance data automatically or based on a predetermined operation of the visitor 1 receives the received current position data and vehicle of the vehicle 3 The appearance data is displayed on the display screen in the formats shown in FIGS. 6 and 7, for example. This corresponds to procedure A8. Accordingly, the visitor 1 can search for the meeter terminal 5 by relying on the position information and appearance information of the meeting vehicle 3.

  By the operation of the communication system as described above, the vehicle navigation device 6 receives the information on the boarding train 7, the information on the appearance of the visitor 1, and the destination address of the visitor terminal 4 (see procedures A1 and A2). Based on the information on the train 7 and train operation data, an appropriate pick-up station 9 and the time to depart to the pick-up station 9 are specified (see procedure A3), and a notice that prompts the pick-up terminal 5 to depart immediately before the departure time (Refer to procedure A4). Immediately after the greeting vehicle 3 arrives at the greeting station 9 by driving the greeting person 2, the received appearance information of the visitor 1 is displayed (see procedure A6), and the position and appearance information of the greeting vehicle 3 are displayed. It transmits to the visitor terminal 4 (refer procedure A7).

  In this way, the vehicle navigation device 6 receives information indicating the appearance of the visitor 1 and causes the display device to display information indicating the appearance of the person at a position where the visitor 1 is greeted based on the received information. Thus, the greeter 2 can find the visitor 1 more easily at the greeting position.

  In addition, since the vehicle navigation device 6 transmits a signal indicating the appearance of the vehicle used by the meeter to the destination of the portable wireless communication terminal carried by the visitor 1, the visitor 1 makes the meeter 2 and the welcome vehicle 3. Can be found more easily.

In the above embodiment, the external storage unit 18 of the vehicle navigation device 6 corresponds to an example of a storage medium. In addition, the control circuit 19 of the vehicle navigation device 6 functions as an example of a receiving unit by receiving data transmitted in the procedure A2, and functions as an example of a specifying unit by executing the procedure A3. When executed, it functions as an example of a display control means, executes procedure A7 as an example of a transmission control means, and executes procedure A4 as a departure time notification means.
(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, in the embodiment described above, the person who receives the guest 2 is not necessarily limited to the visitor, and may be any person (for example, a returnee) as long as the person receives the reception. Further, the pick-up position does not necessarily have to be a station, and may be any place.

  In addition, the navigation device of the present invention is not limited to the vehicle navigation device 6 but may be a portable navigation device that is not specialized for use in a single vehicle. In that case, the navigation device may store the vehicle appearance data of other vehicles in addition to the vehicle appearance data of the normally mounted vehicle. As described above, when the vehicle appearance information of a plurality of vehicles is stored, the navigation device receives the designation of the vehicle mounted at that time from the greeter 2 and receives the vehicle appearance data according to the designation as a visitor terminal. 4 may be transmitted.

  Further, the vehicle navigation device 6 does not transmit a vehicle appearance signal when it arrives at the meeting position, and receives train information data and visitor appearance data before arrival at the meeting position (for example, when departing from the reference position, train information data and visitor appearance data). A vehicle appearance signal may be transmitted to the visitor terminal 4.

  Moreover, the information for specifying the boarding train transmitted by the visitor terminal 4 does not necessarily need to be the name of the station boarding the train for the visit and the departure time of the boarding train. For example, the train is uniquely identified. It may be a code.

  Further, the navigation device may specify the meeting position based on the manual input of the meeting position itself by the meeting person. Alternatively, the meeting position may be received from the visitor terminal 4 and the received position may be specified as the meeting position.

  Further, the navigation device may specify the departure time for the meeting based on the manual input of the departure time itself by the meeting person. Alternatively, the departure time may be received from the visitor terminal 4 and the received time may be specified as the departure time.

  Further, when the vehicle 3 is traveling and the reference position in the procedure A3 is the current position of the vehicle 3 to be picked up, the reference position changes every moment, so that the time from the reference position to the pickup position changes. . In order to cope with such a situation, the navigation device periodically repeats the recalculation of the departure time based on the fact that the greeting vehicle 3 is traveling and the reference position is the current position of the greeting vehicle 3. It may be. Alternatively, this periodic recalculation may be performed regardless of whether the vehicle is running or not running. Similarly, the identification of the meeting position and the meeting time may be repeated periodically.

  Further, the navigation device does not necessarily have to store train operation data. For example, when the train operation data is necessary, the navigation device uses the long-distance data communication intermediary function of the meeter terminal 5 to access the train operation data transmission center on the wide area network and acquire timetable data. You may come to do.

  In addition, the wireless communication device that transmits the train information signal and the person appearance signal by the procedure A1 and the destination wireless communication device to which the vehicle navigation device 6 transmits the vehicle appearance signal by the procedure A7 do not necessarily match. For example, in step A1, a stationary personal computer connected to the wide area network transmits a train information signal and a person appearance signal. In step A7, the vehicle navigation device 6 sends a vehicle appearance signal to the visitor terminal 4. Etc. may be transmitted. In this case, the personal computer may transmit the destination address of the visitor terminal 4 to the meeter terminal 5. Further, the vehicle navigation device 6 specifies the destination address of the visitor terminal 4 to which the vehicle appearance signal or the like is transmitted from the destination address of the personal computer based on the correspondence relationship of the destination addresses stored in advance. It may be like this. Further, the vehicle navigation device 6 may accept the destination address of the visitor terminal 4 by manual input of the greeter 2.

  Further, the navigation device may receive a human appearance signal or the like from the greeted person using the long-distance data communication mediating function in the procedures A1 and A2.

  In addition, when the vehicle navigation device 6 itself includes a wireless communication device that can be connected to a wide area network to realize a long-distance wireless data communication function, the vehicle navigation device 6 and the visitor terminal 4 This wireless communication device can be used for data exchange instead of the meeter terminal 5. In this case, the vehicle navigation device 6 may realize the procedure A4 using the long-distance wireless data communication function of its own wireless communication device. Further, in the case where the own wireless communication device has a telephone communication function, the vehicle navigation device 6 may realize the procedure A4 by calling the meeter terminal 5. In these cases, the vehicle navigation device 6 stores information on the destination address or the destination telephone number of the meeter terminal 5 and uses the information at the time of data transmission and telephone call. Also good.
