(7) Face photo: Image data of a face

  Next, the operation of the navigation device according to Embodiment 1 of the present invention configured as described above will be described with reference to the flowchart shown in FIG. In the following, it is assumed that group travel is performed by the vehicle and the occupant shown in FIG. 2, and the operation of the navigation device mounted on the vehicle X will be described. When the occupant A who is the driver of the vehicle X gets on and the navigation device is activated, the central control unit 18 starts a process for realizing the navigation function (not described) and starts the following process.

  First, occupant information of the own vehicle is acquired (step ST10). That is, the IC tag reading / writing device 1 sends a signal obtained by reading personal information recorded on an IC tag possessed by a passenger of the vehicle X to the IC tag information processing unit 3. The IC tag information processing unit 3 processes the signal sent from the IC tag reading / writing device 1 to reproduce personal information stored in the IC tag and sends it to the central control unit 18 as IC tag information. .

  The central control unit 18 takes in the IC tag information sent from the IC tag information processing unit 3 and counts the number of IC tag information. For example, if occupant A and occupant C are on vehicle X, information on IC tags of occupant A and occupant C is acquired, and the number of IC tag information is set to “2”.

  Next, occupant information of the host vehicle is registered (step ST11). That is, the central control unit 18 stores the IC tag information captured from the IC tag information processing unit 3 in the IC tag information storage unit 4 in step ST10. For example, if an occupant is in all seats of the vehicle X, the number of IC tag information is four, and the IC tag information for four occupants is stored in the IC tag information storage unit 4. At this time, a flag indicating whether the person is in the vehicle or away from the vehicle (hereinafter referred to as “ride status”) is added to the IC tag information and stored in the IC tag information storage unit 4 as occupant information. In other words, register. The boarding status includes “on board” indicating a seated state or “getting off” indicating a state where the user has boarded the vehicle but is currently away from the vehicle. For example, when the passenger X of the vehicle X goes to the toilet before leaving, and leaves the vehicle, the boarding status of the passenger A becomes “getting off”.

  Next, occupant information of the host vehicle is transmitted (step ST12). That is, the central control unit 18 generates vehicle additional information by adding the current position of the host vehicle obtained by the navigation function and the occupant information stored in the IC tag information storage unit 4 to the vehicle information of the host vehicle. The data is sent to the vehicle communication control unit 16. The other vehicle communication control unit 16 sends the vehicle additional information sent from the central control unit 18 to the communication device 17. As a result, the vehicle additional information is transmitted by the communication device 17 to the other vehicle indicated by the vehicle information stored in advance in the memory inside the central control unit 18. For example, if all the passengers are in the vehicle, the occupant information of the occupants A, B, C and D is transmitted to the vehicle X as the latest vehicle additional information of the vehicle X to the vehicle Y and the vehicle Z. Thereby, the passenger | crew situation of the vehicle X can be notified to another vehicle every moment.

  Next, vehicle additional information of other vehicles is acquired (step ST13). That is, the communication device 17 receives the vehicle additional information of the other vehicle transmitted from the navigation device of the other vehicle. For example, the communication device 17 of the vehicle X receives vehicle additional information transmitted from the other vehicle Y and the vehicle Z that travel in a group. The communication device 17 sends the received vehicle additional information to the other vehicle communication control unit 16. The other vehicle communication control unit 16 sends the vehicle additional information of the other vehicle sent from the communication device 17 to the central control unit 18.

  Next, the vehicle additional information of the other vehicle is registered (step ST14). That is, the central control unit 18 stores the vehicle additional information received in step ST13 in the IC tag information storage unit 4 for each vehicle. Thereby, the IC tag information storage unit 4 of the vehicle X stores the vehicle additional information of the other vehicles Y and Z that travel in the group.

  Next, passenger information is notified (step ST15). That is, the central control unit 18 acquires the occupant information registered in step ST11 and the vehicle additional information registered in step ST14 from the IC tag information storage unit 4, and generates them based on the acquired occupant information and vehicle additional information. The displayed data is sent to the drawing control unit 10, and the voice data generated based on the occupant information and the vehicle additional information is sent to the voice reproduction device 12.

  The drawing control unit 10 generates drawing data corresponding to the display data sent from the central control unit 18 and sends it to the monitor 11 as a video signal. The monitor 11 displays the riding conditions of the passengers of the host vehicle and other vehicles in accordance with the video signal sent from the drawing control unit 10. Further, the audio reproduction device 12 generates an audio signal based on the audio data sent from the central control unit 18 and sends it to the speaker 13. The speaker 13 converts the audio signal sent from the audio reproduction device 12 into audio and outputs it.

  FIG. 4 shows some examples of the riding conditions of the passengers of the host vehicle and other vehicles displayed on the monitor 11. FIG. 4A shows an example in which the name of the occupant whose current boarding status, that is, the boarding status of the occupant information is “on board” is displayed for each vehicle such as the host vehicle X, the other vehicle Y, and the other vehicle Z. It is. For example, when only the occupant D of the vehicle X and only the occupant H of the vehicle Y are not occupying, the display is made by removing the occupant D and the occupant H from the example shown in FIG. According to this display, it is possible to grasp the occupant status of the host vehicle and other vehicles at a glance.

  FIG. 4B shows, for each occupant, the occupancy status indicating whether the occupant of the host vehicle X, the other vehicle Y, and the other vehicle Z is getting on or off the vehicle, and the name of the vehicle to get on, based on the boarding status and the boarding vehicle of the occupant information. Is displayed in a list format. For example, when only the occupant D of the vehicle X and the occupant H of the vehicle Y are not occupying, the occupant status of the occupant D and the occupant H in the example shown in FIG. According to this display, it is possible to grasp the boarding status of the occupants of the host vehicle and other vehicles at a glance.

  The monitor 11 can also display the following based on the passenger information and the vehicle additional information. FIG. 4C is an example in which the traveling order of each vehicle is displayed as an illustration icon. This display can be performed by determining the positional relationship between the host vehicle and the other vehicle based on the position of the host vehicle obtained by the navigation function and the vehicle position in the vehicle additional information of the other vehicle acquired in step ST13. it can.

  In the case of displaying in detail, an icon shown in FIG. 4C is selected by an instruction from the input unit 7, and the vehicle seat corresponding to the selected icon is shown in FIG. The layout is displayed, and further, an occupant shown in FIG. 4D is selected by an instruction from the input unit 7, and the occupant's personal information is displayed for each selected occupant in an individual unit as shown in FIG. 4E. It can also be configured as follows. With the above display, it is possible to grasp the positional relationship of vehicles traveling in a group and the boarding situation of a desired vehicle occupant at a glance, and to know personal information of occupants traveling in a group.

  In addition, notification by voice is performed as follows. That is, a notification that the display has been made on the monitor 11 is made by voice, and the contents of the voice notification are contents supplementing changes in the number of passengers. For example, as a notification by voice, refer to the boarding status of the passenger information, notify the name of the passenger who is “on board”, or notify the name of the passenger who is “on board” Can be configured to By this notification by voice, it is possible to check the state of the passengers of the host vehicle and other vehicles without looking at the screen of the monitor 11. In addition, in response to the input of confirmation of the occupant status of the host vehicle from the input unit 7, display on the monitor 11 and notification by voice can be performed.

  As a specific example, consider a case where an occupant D is not in the vehicle X. In this case, since the boarding status of the occupant information is “discarding”, the occupant status of the occupant D of the vehicle X is “dismounting”, and the occupant information of the vehicle X is displayed together with the occupant information of the other occupants A, B, and C. Y and vehicle Z are notified. In each vehicle, it can be confirmed on the display of the monitor 11 as shown in FIG. 4B that the occupant D (vehicle X) is not in the vehicle. In addition, this non-boarding notification is simultaneously transmitted to each vehicle by voice.

  When the above notification of occupant information is completed, it is then checked whether all the groups are in the vehicle (step ST16). That is, the user of the vehicle confirms whether all of the passengers of the host vehicle and other vehicles traveling in a group have been prepared, and inputs the confirmation result from the input unit 7. If it is input from the input unit 7 that all members are not present, the sequence returns to step ST10 and the above-described processing is repeated.

  On the other hand, when it is input in step ST16 that all the members are ready, departure is notified to other vehicles (step ST17). That is, the central control unit 18 generates a message indicating departure and sends it to the other vehicle communication control unit 16. The other vehicle communication control unit 16 sends a message indicating departure from the central control unit 18 to the communication device 17. As a result, a message to the effect of departure is transmitted by communication device 17 to other vehicles (vehicle Y and vehicle Z) indicated by the vehicle information stored in advance in the memory inside central control unit 18. Thus, the process of the navigation device mounted on the vehicle X is completed.

  As described above, according to the navigation device in accordance with Embodiment 1 of the present invention, it is possible to board in a distributed manner without being aware of the vehicle capacity from the number of vehicles and the number of participants, and shorten the time from set to departure. It is possible to plan and all the passenger information can be grasped. Further, since an IC tag is used as a recording medium, personal information can be automatically acquired, and troublesome registration work is not necessary. Further, since the occupant information is displayed on the screen, it is possible to confirm on the screen at the same time as the boarding without having to call and confirm whether all the occupants are present. Furthermore, since the occupant information is displayed on the screen at the same time that the occupant information is displayed, it is possible to confirm whether all the occupants are present without looking at the screen.

  In the navigation device according to the first embodiment described above, an IC tag is used as a recording medium and the content recorded on the IC tag is read by wireless communication. However, for example, a mobile phone is used as the recording medium. The content recorded in the cellular phone can be used and read by wireless communication using, for example, Bluetooth.

That is, the central control unit 18 acquires from the IC tag information storage unit 4 vehicle additional information to which the passenger information registered in step ST11 and the image information indicating the state in the vehicle registered in step ST14 are added. The display data generated based on the acquired occupant information and vehicle additional information is sent to the drawing control unit 10, and the audio data generated based on the occupant information and vehicle additional information is sent to the audio reproduction device 12. Thereby, in addition to the display shown in FIG. 4A, for example, as shown in FIG. 5, an in-vehicle image showing the inside of the vehicle and a message showing the displayed vehicle are displayed.

  Next, it is checked whether all the groups are on board (step ST16). If it is determined in step ST16 that all the groups are on board, the sequence returns to step ST10, and the above-described processing is repeated. On the other hand, when it is determined in step ST16 that all the groups are not in the vehicle, the departure is notified to other vehicles (step ST17). Thereafter, the processing of the navigation device mounted on the vehicle X ends.

  As described above, according to the navigation device in accordance with Embodiment 2 of the present invention, all the occupants who are traveling in a group can more specifically know the situation inside the other vehicle through the monitor 11. Therefore, for example, it is possible to use such that the first meeting people confirm each other's faces.

Embodiment 3 FIG.
The navigation device according to Embodiment 3 of the present invention is such that in the navigation device according to Embodiment 1, presence / absence of occupant differences is detected to determine whether departure is possible. The configuration of the navigation device according to the second embodiment is the same as the configuration of the navigation device according to the first embodiment shown in FIG.

  Next, the operation of the navigation device according to the second embodiment will be described with reference to the flowchart shown in FIG. The process shown in the flowchart of FIG. 6 is continued following the notification of departure to another vehicle (step ST17) after the process of the navigation device according to the first embodiment shown in the flowchart of FIG. 3 is completed. Execution is started. In the following description, the same reference numerals as those used in the flowchart of FIG. 3 are given to steps for executing the same or corresponding processes as those of the navigation apparatus according to the first embodiment shown in the flowchart of FIG. The description is simplified.

  When the notification of departure to the other vehicle of the navigation device according to the first embodiment shown in the flowchart of FIG. 3 (step ST17) is completed, occupant information for all occupants is subsequently set (step ST20). That is, the central control unit 18 stores the occupant information of the own vehicle and the occupant information of other vehicles stored in the IC tag information storage unit 4 in the IC tag information storage unit 4 as all occupant information. Since all members of the group are on board at this time, the occupant information of all the groups is stored in the IC tag information storage unit 4 as all occupant information. In the occupant situation shown in FIG. 2, the occupant information for a total of 12 people of 4 people, 6 people, and 2 people who are in 3 vehicles X, Y and Z is the IC tag information storage unit 4 Stored in

  Next, occupant information of the host vehicle is acquired (step ST10). Next, occupant information of the host vehicle is registered (step ST11). Next, occupant information of the host vehicle is transmitted (step ST12). Next, vehicle additional information of other vehicles is acquired (step ST13). Next, the vehicle additional information of the other vehicle is registered (step ST14).

  Next, an occupant difference is extracted (step ST21). That is, the central control unit 18 saves the occupant information stored in the IC tag information storage unit 4 in step ST11, the vehicle additional information stored in the IC tag information storage unit 4 in step ST14, and the IC tag information storage in step ST20. The total occupant information stored in the section 4 is compared to detect the number of people who are not on board and the names of people who are not on board. That is, the number and the name of the occupant whose occupant status of the occupant information stored as all the occupant information is “getting off” are detected.

  For example, the occupant status changes when time elapses after the process of step ST20 is executed and the service area is reached. For example, only the occupant D of the vehicle X and the occupant H of the vehicle Y shown in FIG. In the case of, since only the boarding status of the passengers D and H is “getting off”, two people are detected as the number of people who are not in the vehicle, and the passengers D and H are detected as the names of the people who are not in the vehicle. . Further, when the departure time approaches and all the people get on, the passenger status shown in FIG. 3 is obtained, and there is no difference from all the passenger information.

  Next, it is examined whether or not there is a difference (step ST22). That is, the central control unit 18 checks whether or not the number of passengers detected in step ST21 is “0”. If “0”, the central control unit 18 stores it in the IC tag information storage unit 4 in step ST11. It is determined that there is no difference between the occupant information and the additional vehicle information stored in the IC tag information storage unit 4 in step ST14 and all the occupant information stored in the IC tag information storage unit 4 in step ST20.

  If it is determined in step ST22 that there is a difference, then notification that departure is not possible is performed (step ST24). That is, the central control unit 18 generates a message indicating that departure is not possible, and sends the message to the drawing control unit 10 as display data together with the number of people who have not boarded and the names of people who have not boarded, detected in step ST21. . The drawing control unit 10 generates drawing data corresponding to the display data sent from the central control unit 18 and sends it to the monitor 11 as a video signal. The monitor 11 displays a message indicating that departure is not possible, the number of people who are not on board, and the names of people who are not on board according to the video signal sent from the drawing control unit 10.

  In addition, the central control unit 18 generates a message indicating that departure is impossible, and sends the message to the audio reproduction device 12 as audio data together with the number of people who have not boarded and the names of people who have not boarded, detected in step ST21. . The audio reproduction device 12 generates an audio signal based on the audio data sent from the central control unit 18 and sends it to the speaker 13. The speaker 13 converts the audio signal sent from the audio reproduction device 12 into audio and outputs it. As a result, a message indicating that departure is not possible, the number of people who are not on board, and the names of people who are not on board are output by voice. Thereafter, the sequence returns to step ST10, and the above-described processing is repeated.

  If it is determined in step ST22 that there is no difference, next, a notice that departure is possible is performed (step ST23). That is, the central control unit 18 generates a message indicating that the departure is possible, sends the message to the drawing control unit 10 as display data, and sends it to the voice reproduction device 12 as voice data. The drawing control unit 10 generates drawing data corresponding to the display data sent from the central control unit 18 and sends it to the monitor 11 as a video signal. The monitor 11 displays a message indicating that the departure is possible according to the video signal sent from the drawing control unit 10. The audio reproduction device 12 generates an audio signal based on the audio data sent from the central control unit 18 and sends it to the speaker 13. The speaker 13 converts the audio signal sent from the audio reproduction device 12 into audio and outputs it. As a result, a message that the departure is possible is output by voice.
