[0008] Referring to Figure 1, Figure 1 diagrammatically shows the exterior of a vehicle 1. In the example shown in Figure 1, an information display screen 2 that is visible from the outside, such as digital signage, a so-called electronic billboard, is installed on the side of the vehicle 1, and advertisements and various other information are displayed on this information display screen 2. In the example shown in Figure 1, the vehicle 1 is an autonomous vehicle, and Figure 2 diagrammatically shows the functions of the vehicle 1 shown in Figure 1.

[0009] 2, reference numeral 10 denotes a vehicle drive section for applying drive force to the drive wheels of vehicle 1, 11 denotes a braking device for braking vehicle 1, 12 denotes a steering device for steering vehicle 1, and 13 denotes an electronic control unit mounted in vehicle 1. As shown in Fig. 2, electronic control unit 13 is made up of a digital computer and includes a CPU (microprocessor) 15, memory 16 consisting of ROM and RAM, and input / output ports 17, all connected to each other by a bidirectional bus 14. As shown in Fig. 2, information display screen 2 is connected to electronic control unit 13, and the operation of information display screen 2 is controlled by electronic control unit 13.

[0010] Meanwhile, as shown in FIG. 2 , the vehicle 1 is equipped with various sensors 18 necessary for the vehicle 1 to perform autonomous driving, namely, sensors for detecting the state of the vehicle 1 and surrounding detection sensors for detecting the surroundings of the vehicle 1. In this case, the sensors for detecting the state of the vehicle 1 include an acceleration sensor, a speed sensor, and an azimuth sensor. The surrounding detection sensors for detecting the surroundings of the vehicle 1 include an on-board camera for capturing images of the front, sides, and rear of the vehicle 1, a lidar (LIDAR), a radar, etc. The vehicle 1 is also equipped with a GNSS (Global Navigation Satellite System) receiver 19, a map data storage device 20, a navigation device 21, and an operation unit 22 for performing various operations. The GNSS receiver 19 can detect the current position of the vehicle 1 (e.g., the latitude and longitude of the vehicle 1) based on information obtained from multiple artificial satellites. Therefore, the current position of the vehicle 1 can be acquired by the GNSS receiver 19. For example, a GPS receiver is used as the GNSS receiver 19.

[0011] These various sensors 18, GNSS receiver 19, map data storage device 20, navigation device 21, and operation unit 22 are connected to an electronic control unit 13. Meanwhile, the vehicle drive unit 10 is composed of an electric motor, and this electric motor is drive-controlled in accordance with an output signal from the electronic control unit 13. Furthermore, braking control of the vehicle 3 is performed by a braking device 11 in accordance with an output signal from the electronic control unit 13, and steering control of the vehicle 3 is performed by a steering device 12 in accordance with an output signal from the electronic control unit 13. Furthermore, as shown in FIG. 2, the electronic control unit 13 is connected to a communication device 23 that can communicate with the outside.

[0012] When information such as an advertisement is displayed on the information display screen 2 of the vehicle 1, a person who views the information display screen 2 may want to store the information display screen 2 in their own mobile device, for example, so that they can review the information at their leisure later. In this case, the person who wants to store the information display screen 2 in their mobile device is the person viewing the information display screen 2 and who is near the vehicle 1. Therefore, in the first embodiment of the present invention, as shown in FIG. 3, when the distance between the vehicle 1 and the mobile device 3 is within a set range S, data required to display the content of the information display screen 2 on the screen of the mobile device 3 is transmitted from the vehicle 1 to the mobile device 3, or this data can be received by the mobile device 3 from the vehicle 1. In FIG. 3, 4 indicates the person carrying the mobile device 3.

[0013] FIG. 4 shows an information display processing routine executed in the electronic control unit 13 installed in the vehicle 1 to implement this first embodiment.

[0014] Referring to FIG. 4, first, in step 30, detection signals from a front camera, a side camera, a rear camera, a lidar, a radar, etc. mounted on the vehicle 1 are acquired. Next, in step 31, the mobile terminal 3 is detected using an object detection method based on these detection signals. Next, in step 32, the position of the mobile terminal 3 is detected based on these detection signals, and the distance between the vehicle 1 and the mobile terminal 3 is detected based on the position of the mobile terminal 3. In this case, various methods are known for detecting the distance between the vehicle 1 and the mobile terminal 3, and for example, a beacon can be used to detect the distance between the vehicle 1 and the mobile terminal 3. In this case, for example, a beacon signal transmitter is installed in the vehicle 1, the beacon signal is received by the mobile terminal 3, the distance between the vehicle 1 and the mobile terminal 3 is calculated from the beacon signal strength, and information about the calculated distance is transmitted to the vehicle 1.

[0015] Once the distance between the vehicle 1 and the mobile terminal 3 has been calculated, the process proceeds to step 33, where it is determined whether the distance between the vehicle 1 and the mobile terminal 3 is within the set range S. If it is determined that the distance between the vehicle 1 and the mobile terminal 3 is within the set range S, the process proceeds to step 34, where a display process is performed to display the content displayed on the information display screen 2 on the screen of the mobile terminal 3. That is, a process is performed in which data required to display the content displayed on the information display screen 2 on the screen of the mobile terminal 3 is transmitted from the vehicle 1 to the mobile terminal 3, or a process is performed in which this data can be received by the mobile terminal 3 from the vehicle 1.

[0016] In this case, there are various ways of performing this display process. Representative methods include a method of immediately displaying the display content of the information display screen 2 on the screen of the mobile terminal 3, or a method of immediately displaying information including the display content of the information display screen 2. As another method, it is also possible to display a message on the screen of the mobile terminal 3 indicating that the display content of the information display screen 2 has been received. Alternatively, an app for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 may be provided, and the display content of the information display screen 2 may be immediately displayed on the screen of the mobile terminal 3 only when the app is started on the mobile terminal 3. Alternatively, the app may be started on the mobile terminal 3, and data required to display the display content of the information display screen 2 on the screen of the mobile terminal 3 may be received from the vehicle 1.

[0017] On the other hand, when it is determined in step 33 that the distance between the vehicle 1 and the mobile terminal 3 is greater than the set range S, the process proceeds to step 35, where the display process for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited. In this case, the display content of the information display screen 2 is not displayed on the screen of the mobile terminal 3.

[0018] Figure 5 shows an information display processing routine for implementing a modified example of the first embodiment shown in Figure 4. This routine is executed in the electronic control unit 13 installed in the vehicle 1. Steps 30 to 35 of the information display processing routine shown in Figure 5 are the same as steps 30 to 35 of the information display processing routine shown in Figure 4, respectively. The only difference between the information display processing routine shown in Figure 5 and the information display processing routine shown in Figure 4 is that steps 36 and 37 have been added to the information display processing routine shown in Figure 5. Therefore, a description of steps 30 to 35 of the information display processing routine shown in Figure 5 will be omitted, and only steps 36 and 37 of the information display processing routine shown in Figure 5 will be described.

[0019] 5, in this modification of the first embodiment, when it is determined in step 33 that the distance between the vehicle 1 and the mobile terminal 3 is within the set range S, the process proceeds to step 36, where a determination process is performed as to whether or not the display content of the information display screen 2 can be displayed on the screen of the mobile terminal 3. Next, in step 37, when it is determined as a result of the determination process that the display content of the information display screen 2 can be displayed, the process proceeds to step 34, where a display process is performed to display the display content of the information display screen 2 on the screen of the mobile terminal 3. On the other hand, when it is determined in step 37 that the display content of the information display screen 2 cannot be displayed, the process proceeds to step 35, where the display process to display the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited.

[0020] To give a specific example, the preferences of the owner 4 of the mobile terminal 3 are stored in memory 16, and in step 36, the preferences of the owner 4 of the mobile terminal 3 are compared with the display content of the information display screen 2, and if the display content of the information display screen 2 matches the preferences of the owner 4 of the mobile terminal 3, it is determined that the display content of the information display screen 2 can be displayed. Therefore, in this case, if the display content of the information display screen 2 matches the preferences of the owner 4 of the mobile terminal 3, display processing is performed to display the display content of the information display screen 2 on the screen of the mobile terminal 3. On the other hand, if the display content of the information display screen 2 does not match the preferences of the owner 4 of the mobile terminal 3, display processing to display the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited.

[0021] In this case, it is possible to configure the system so that the owner 4 of the mobile terminal 3 stores the preferences of the owner 4 of the mobile terminal 3 in advance in the memory 16. Also, it is possible to configure the system so that the display contents of the information display screen 2 that have been displayed on the screen of the mobile terminal 3 by the owner 4 of the mobile terminal 3 are classified and stored in the memory 16, the class of the display contents of the information display screen 2 stored in the memory 16 is compared with the class of the display contents of the currently displayed information display screen 2, and if these classes match, it is determined that the display contents of the information display screen 2 can be displayed. Also, it is possible to configure the system so that the owner 4 of the mobile terminal 3 stores the display contents of the information display screen 2 that he or she wishes to receive in the memory 16 in advance, and the display contents of the information display screen 2 can be displayed on the screen of the mobile terminal 3 only if the display contents of the currently displayed information display screen 2 match the display contents of the information display screen 2 stored in the memory 16.

[0022] Furthermore, in step 36, it is also possible to perform a process of determining whether or not the display content of the information display screen 2 can be displayed on the screen of the mobile terminal 3, based on the action of the owner 4 of the mobile terminal 3 and the orientation of the screen of the mobile terminal 3. For example, it is also possible to detect the action of the owner 4 of the mobile terminal 3 and the orientation of the screen of the mobile terminal 3 based on images captured by the front camera, side camera, and rear camera, and to determine that the display content of the information display screen 2 can be displayed when the action of the owner 4 of the mobile terminal 3 is a predetermined action, for example, an action of taking the mobile terminal 3 out from under his clothes to look at the screen, or when the orientation of the screen of the mobile terminal 3 is a predetermined direction, for example, the direction of the eyes of the owner 4 of the mobile terminal 3.

[0023] Figure 6 shows an information display processing routine for implementing yet another modified example of the first embodiment shown in Figure 4. This routine is executed in the electronic control unit 13 installed in the vehicle 1. Steps 30 to 35 of the information display processing routine shown in Figure 6 are the same as steps 30 to 35 of the information display processing routine shown in Figure 4, respectively. The only difference between the information display processing routine shown in Figure 6 and the information display processing routine shown in Figure 4 is that steps 36 to 39 have been added to the information display processing routine shown in Figure 6. Therefore, a description of steps 30 to 35 of the information display processing routine shown in Figure 6 will be omitted, and only steps 36 to 39 of the information display processing routine shown in Figure 6 will be described.

[0024] 6, in yet another modification of the first embodiment, when it is determined in step 33 that the distance between the vehicle 1 and the mobile terminal 3 is within the set range S, the process proceeds to step 36, where a determination process is performed as to whether or not the display content of the information display screen 2 can be displayed on the screen of the mobile terminal 3, as in Fig. 5. Next, in step 37, when it is determined as a result of the determination process that the display content of the information display screen 2 can be displayed, the process proceeds to step 34, as in Fig. 5, where a display process is performed to display the display content of the information display screen 2 on the screen of the mobile terminal 3. On the other hand, when it is determined in step 37 that the display content of the information display screen 2 cannot be displayed, the process proceeds to step 38, where the display process to display the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited, and then the process proceeds to step 39, where the alarm function of the mobile terminal 3 is activated.

[0025] To give a specific example, in step 36, it is detected whether or not the vehicle 1 is moving, and when the vehicle 1 is not moving, it is determined that the display content of the information display screen 2 can be displayed. Therefore, in this case, when the vehicle 1 is not moving, a display process is performed to display the display content of the information display screen 2 on the screen of the mobile terminal 3. On the other hand, when the vehicle 1 is moving, the display process to display the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited, and the owner 4 of the mobile terminal 3 is prevented from coming into contact with the moving vehicle 1. Therefore, an alarm function of the mobile terminal 3 is activated. In this case, it is also possible to configure the device so that it is determined that the contents to be displayed on the information display screen 2 can be displayed when the vehicle 1 is traveling at a predetermined speed, for example, 5 km / h or less.

[0026] In addition, whether or not the owner 4 of the mobile terminal 3 is moving is detected based on detection signals from a front camera, side camera, rear camera, LIDAR, radar, etc. mounted on the vehicle 1, and when the owner 4 of the mobile terminal 3 is trying to obtain the display contents of the information display screen 2 while moving, for example, when it is detected that the owner 4 of the mobile terminal 3 is moving, if the vehicle 1 receives a request to obtain the display contents of the information display screen 2, it is possible to configure the system so that the display process for displaying the display contents of the information display screen 2 on the screen of the mobile terminal 3 is prohibited and the alarm function of the mobile terminal 3 is activated.

[0027] In addition, an application is provided for displaying the display contents of the information display screen 2 on the screen of the mobile terminal 3, and it is also possible to configure the application to perform a determination process as to whether or not the display contents of the information display screen 2 can be displayed on the screen of the mobile terminal 3 only when the application is started on the mobile terminal 3.

[0028] A second embodiment of the present invention is shown in Figure 7. In this second embodiment, as shown in Figure 7, a relatively wide first range extending to the side of vehicle 1 and a second range within the first range that is significantly narrower than the first range and closer to vehicle 1 are set, and when mobile terminal 3 is within the first range but outside the second range, data required to display the content of information display screen 2 on the screen of mobile terminal 3 is transmitted from vehicle 1 to mobile terminal 3, or this data can be received by mobile terminal 3 from vehicle 1, and when mobile terminal 3 is within the second range, display processing for displaying the content of information display screen 2 on the screen of mobile terminal 3 is prohibited and an alarm function of mobile terminal 3 is activated.

[0029] FIG. 8 shows an information display processing routine executed in the electronic control unit 13 installed in the vehicle 1 to implement this second embodiment.

[0030] 8, steps 40 to 42 are similar to steps 30 to 32 of the first embodiment shown in Fig. 4. That is, in step 40, detection signals from a front camera, a side camera, a rear camera, a LIDAR, a radar, etc. mounted on the vehicle 1 are acquired, then in step 41, the mobile terminal 3 is detected using an object detection method based on these detection signals, and then in step 42, the position of the mobile terminal 3 is detected based on these detection signals.

[0031] When the position of the mobile terminal 3 is detected, the process proceeds to step 43, where it is determined whether the position of the mobile terminal 3 is within the first range shown in FIG. 7. When it is determined that the position of the mobile terminal 3 is not within the first range shown in FIG. 7, the process proceeds to step 44, where display processing for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited. In this case, the display content of the information display screen 2 on the screen of the mobile terminal 3 is not displayed. On the other hand, when it is determined that the position of the mobile terminal 3 is within the first range shown in FIG. 7, the process proceeds to step 45, where it is determined whether the position of the mobile terminal 3 is within the second range shown in FIG. 7. When it is determined that the position of the mobile terminal 3 is not within the second range shown in FIG. 7, the process proceeds to step 46, where display processing for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 is performed. That is, processing for transmitting data necessary for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 from the vehicle 1 to the mobile terminal 3, or processing for enabling the mobile terminal 3 to receive this data from the vehicle 1, is performed.

[0032] In this case, as in the first embodiment, there are various ways of performing this display process. A typical method is to immediately display the display contents of the information display screen 2 on the screen of the mobile terminal 3. As another method, it is also possible to display on the screen of the mobile terminal 3 a message indicating that the display contents of the information display screen 2 have been received. Alternatively, an app for displaying the display contents of the information display screen 2 on the screen of the mobile terminal 3 may be prepared, and the display contents of the information display screen 2 may be immediately displayed on the screen of the mobile terminal 3 only when the app is started on the mobile terminal 3. Alternatively, the app may be started on the mobile terminal 3, and data required for displaying the display contents of the information display screen 2 on the screen of the mobile terminal 3 may be received from the vehicle 1.

[0033] On the other hand, when it is determined in step 45 that the position of the mobile terminal 3 is within the second range shown in Fig. 7, the process proceeds to step 47, where the display process for displaying the content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited. In this case, the content of the information display screen 2 is not displayed on the screen of the mobile terminal 3. Next, the process proceeds to step 48, where the alarm function of the mobile terminal 3 is activated.

[0034] Figure 9 shows an information display processing routine for carrying out a modified example of the second embodiment shown in Figure 8. This routine is executed in the electronic control unit 13 installed in the vehicle 1. Steps 40 to 48 of the information display processing routine shown in Figure 9 are the same as steps 40 to 48 of the information display processing routine shown in Figure 8, respectively, and the only difference between the information display processing routine shown in Figure 9 and the information display processing routine shown in Figure 8 is that steps 49 and 50 have been added to the information display processing routine shown in Figure 9. Therefore, a description of steps 40 to 48 of the information display processing routine shown in Figure 9 will be omitted, and only steps 49 and 50 of the information display processing routine shown in Figure 9 will be described.

[0035] 9, in this modified example of the second embodiment, when it is determined in step 45 that the position of the mobile terminal 3 is not within the second range shown in Fig. 7, the process proceeds to step 49, where a determination process is performed to determine whether or not the display content of the information display screen 2 can be displayed on the screen of the mobile terminal 3. Next, in step 50, when it is determined as a result of the determination process that the display content of the information display screen 2 can be displayed, the process proceeds to step 46, where a display process is performed to display the display content of the information display screen 2 on the screen of the mobile terminal 3. On the other hand, when it is determined in step 50 that the display content of the information display screen 2 cannot be displayed, the process proceeds to step 47, where the display process to display the display content of the information display screen 2 on the screen of the mobile terminal 3 is prohibited, and then the process proceeds to step 48, where the alarm function of the mobile terminal 3 is activated.

[0036] The display determination process performed in step 49 of this modified example of the second embodiment is similar to the display determination process performed in step 36 of FIG. 6 , which shows another modified example of the first embodiment. For example, it is detected whether the vehicle 1 is moving, and when the vehicle 1 is moving, it is determined that the display content of the information display screen 2 cannot be displayed. Alternatively, when the owner 4 of the mobile terminal 3 is attempting to obtain the display content of the information display screen 2 while moving, it is determined that the display content of the information display screen 2 cannot be displayed. In this case, too, it is possible to configure the system so that an app for displaying the display content of the information display screen 2 on the screen of the mobile terminal 3 is provided, and the process of determining whether the display content of the information display screen 2 can be displayed on the screen of the mobile terminal 3 is performed only when the app is launched on the mobile terminal 3.

[0037] Thus, in an embodiment of the present invention, in an information display system for displaying the display contents of an information display screen 2 installed in a vehicle 1 so that it can be seen from outside on the screen of a mobile terminal 3, when the positional relationship between the vehicle 1 and the mobile terminal 3 becomes a predetermined positional relationship, the data necessary to display the display contents of the information display screen 2 on the screen of the mobile terminal 3 is transmitted from the vehicle 1 to the mobile terminal 3, or this data can be received by the mobile terminal 3 from the vehicle 1.
