The distance determination unit 64 determines whether or not the occupant 92 of the vehicle 10 is present within a predetermined distance range 90 from the vehicle 10, and specifically, as shown in fig. 4, determines whether or not the occupant 92 of the vehicle 10 is present within a distance range 90 having a radius R (for example, R is 50 m) from the center position of the vehicle 10.
To explain in more detail, the occupant 92 carries the mobile terminal 38, such as a smartphone or a smart key of the vehicle 10. Here, in the case where the distance range 90 is a communicable range of the communication unit 20, if the mobile terminal 38 is located within the distance range 90, wireless communication can be performed between the communication unit 20 and the mobile terminal 38. When the communication unit 20 and the mobile terminal 38 are connected by wireless, the distance determination unit 64 determines that the mobile terminal 38 is located within the distance range 90, that is, the passenger 92 carrying the mobile terminal 38 is located within the distance range 90.
Alternatively, when the communication unit 20 receives the positional information of the mobile terminal 38 by performing wireless communication between the communication unit 20 and the mobile terminal 38, the information acquisition unit 58 acquires the received positional information of the mobile terminal 38. The distance determination unit 64 calculates the distance between the position of the mobile terminal 38 and the position of the vehicle 10 using the acquired position information of the mobile terminal 38 and the current position information of the vehicle 10, and if the calculated distance is shorter than the radius R, it can be determined that the mobile terminal 38 is present within the distance range 90, that is, the occupant 92 carrying the mobile terminal 38 is within the distance range 90.
Therefore, as shown in fig. 4, when the passenger 92 carrying the mobile terminal 38 is outside the distance range 90, the distance determination unit 64 can determine that the passenger 92 carrying the mobile terminal 38 is not within the distance range 90 by performing the above determination processing.
When the distance determination unit 64 determines that the passenger 92 carrying the mobile terminal 38 is within the distance range 90, the display control unit 62 stops displaying the content in the display area 70 according to the determination result.
When the distance determination unit 64 determines that the passenger 92 carrying the mobile terminal 38 is not within the distance range 90, the display control unit 62 continues to display the content in the display area 70.
[2. operation of the present embodiment ]
Next, the operation of the display control device 12 will be described. In this operation description, a case will be described in which the vehicle 10 is the own car of the occupant 92, and when the occupant 92 parks the vehicle 10 in a parking lot or the like of a commercial facility and moves the portable terminal 38 from the vehicle 10 to the outside of the distance range 90, the display of the content in the display area 70 is started.
Fig. 5 is a flowchart showing the operation of the display control device 12 (see fig. 1).
First, the occupant 92 (see fig. 4) stops the vehicle 10 and moves the portable terminal 38 from the vehicle 10 to the outside of the distance range 90. Thereafter, in step S1, the information acquisition unit 58 acquires the own vehicle position information of the vehicle 10 from, for example, the navigation device 30 or the positioning unit 33.
In step S2, the display control unit 62 reads out appropriate content at the current position from the storage unit 56 based on the vehicle position information and the like acquired by the information acquisition unit 58, and displays the read-out content in the display area 70. The display area 70 displays contents toward the outside of the vehicle 10. In this case, when the distance determination unit 64 determines that the wireless communication between the communication unit 20 and the mobile terminal 38 is not possible, or the distance between the vehicle 10 and the mobile terminal 38 is longer than the radius R, the display control unit 62 may start displaying the content in the display area 70.
By displaying the content, the person who views the content gathers in the periphery of the vehicle 10. The gathered people sometimes watch the vehicle 10 in addition to the content. In particular, when popular contents are displayed, people tend to gather around the vehicle 10, and the vehicle 10 tends to be concerned. In this state, the occupant 92 located outside the vehicle 10 is inconveniently entering the vehicle 10 under the line of sight of the person viewing the content and the vehicle 10.
Therefore, in the next step S3, the distance determination unit 64 determines whether or not the mobile terminal 38 carried by the occupant 92 is present within the distance range 90.
As shown in fig. 4, when the occupant 92 carrying the mobile terminal 38 is located outside the distance range 90, the wireless communication between the communication unit 20 and the mobile terminal 38 is not possible, or the distance between the vehicle 10 and the mobile terminal 38 is longer than the radius R. In this case, the distance determination unit 64 determines that the passenger 92 carrying the portable terminal 38 is not within the distance range 90 (step S3: NO). When a negative determination result is received in step S3, the display control unit 62 continues to display the content in the display area 70.
On the other hand, when the occupant 92 carrying the mobile terminal 38 enters the distance range 90, the wireless communication between the communication unit 20 and the mobile terminal 38 is enabled, or the distance between the vehicle 10 and the mobile terminal 38 is shorter than the radius R. In this case, the distance determination unit 64 determines that the passenger 92 carrying the portable terminal 38 is within the distance range 90 (step S3: YES).
In next step S4, the display controller 62 receives the affirmative determination in step S3, and stops displaying the content in the display area 70. Accordingly, since the display of the content has been stopped, the person who views the content around the vehicle 10 and the vehicle 10 leaves the vehicle 10. The occupant 92 can enter the vehicle 10 and start the vehicle 10 after confirming that no person is present around the vehicle 10.
The processing of the flowchart of fig. 5 can be repeatedly executed at predetermined time intervals. Therefore, even in the case where the content continues to be displayed in the current process (step S3: NO), it is possible to stop displaying the content in the display area 70 by performing the processes of steps S3, S4 in the next process.
[3 ] modification of the present embodiment ]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the scope of the present invention.
In the above description, the case where the vehicle 10 is a self-automobile of the occupant 92 is described. The present embodiment can be applied to the vehicle 10 other than the home automobile. In addition, when the vehicle 10 starts to move after the content display in step S4 in fig. 5 is stopped, the content may be displayed in the display area 70 of the vehicle 10 during traveling.
[4. effect of the present embodiment ]
