DETAILED DESCRIPTION OF THE INVENTION

[0008] Referring to Figure 1, 1 indicates a roadway, 2 indicates a sidewalk, 3 indicates a vehicle equipped with digital signage 4 (a so-called electronic signage), 5 indicates a general vehicle, 6 indicates a management server, and 7 indicates a pedestrian carrying a mobile terminal 8. In the example shown in Figure 1, the digital signage-equipped vehicle 3 and the general vehicle 5 are configured to be able to communicate with each other in short distances, and the digital signage-equipped vehicle 3 and the mobile terminal 8 are also configured to be able to communicate with each other in short distances. Furthermore, the digital signage-equipped vehicle 3 and the management server 6 are configured to be able to communicate with each other via a communication network, and the general vehicle 5 and the management server 6 are also configured to be able to communicate with each other via a communication network.

[0009] In the example shown in FIG. 1, the digital signage-equipped vehicle 3 is an autonomous vehicle, and FIG. 2 diagrammatically shows a portion of this digital signage-equipped vehicle 3. Referring to FIG. 2, reference numeral 10 denotes a vehicle drive unit for applying driving force to the drive wheels of the vehicle 3, 11 denotes a braking device for braking the vehicle 3, 12 denotes a steering device for steering the vehicle 3, and 13 denotes an electronic control unit mounted in the vehicle 3. As shown in FIG. 2, the electronic control unit 13 is 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, the digital signage 4 is connected to the electronic control unit 13, and the operation of the digital signage 4 is controlled by the electronic control unit 13.

[0010] Meanwhile, as shown in FIG. 2 , the vehicle 3 is equipped with various sensors 18 necessary for the vehicle 3 to perform autonomous driving, namely, sensors for detecting the state of the vehicle 3 and surrounding detection sensors for detecting the surroundings of the vehicle 3. In this case, acceleration sensors, speed sensors, and azimuth sensors are used as sensors for detecting the state of the vehicle 3, and surrounding detection sensors for detecting the surroundings of the vehicle 3 include on-board cameras that capture images of the front, sides, and rear of the vehicle 3, LIDAR, radar, etc. The vehicle 3 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 3 (e.g., the latitude and longitude of the vehicle 3) based on information obtained from multiple artificial satellites. Therefore, the current position of the vehicle 3 can be obtained 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. As shown in FIG. 1, a camera 9 capable of capturing images of the surrounding area in any direction is installed on the roof of the digital signage-equipped vehicle 3, and image data captured by this camera 9 is sent to the electronic control unit 13. Meanwhile, the vehicle drive unit 10 is composed of an electric motor, and the drive of this electric motor is controlled in accordance with the output signal of the electronic control unit 13. Braking control of the vehicle 3 is performed by a braking device 11 in accordance with the output signal of the electronic control unit 13, and steering control of the vehicle 3 is performed by a steering device 12 in accordance with the output signal of the electronic control unit 13. As shown in FIG. 2, the electronic control unit 13 is connected to a communication device 23 capable of communicating with the outside world.

[0012] In the example shown in Fig. 1, the general vehicle 5 is also an autonomous vehicle, and Fig. 3 shows a schematic representation of this general vehicle 5. This general vehicle 5 does not have the digital signage 4 or the camera 9, but has other components similar to those of the digital signage-equipped vehicle 3 shown in Fig. 2. Therefore, in Fig. 3, components similar to those shown in Fig. 2 are given the same reference numerals, and descriptions of these components will be omitted.

[0013] In the example shown in FIG. 1, the digital signage 4 is a liquid crystal display, an organic electroluminescence display, or an LED display. Matrix The digital signage 4 of the digital signage-equipped vehicle 3 displays advertisements requested by advertisers or information including advertisements. Display control of the digital signage 4 is performed by an electronic control unit 13 installed in the digital signage-equipped vehicle 3. First, a digital signage display processing routine executed in the electronic control unit 13 will be described with reference to FIG. 4.

[0014] Referring to Fig. 4, first, in step 30, it is determined whether a display request has been issued indicating that an advertisement requested by an advertiser or information including an advertisement should be displayed on the digital signage 4. This display request is issued in the electronic control unit 13, for example, when a date and time set in advance based on a contract with the advertiser is reached. If it is determined that this display request has not been issued, the process jumps to step 34. On the other hand, if it is determined that a display request has been issued, the process proceeds to step 31, where a display flag is set indicating that information including an advertisement should be displayed on the digital signage 4. Next, the process proceeds to step 32.

[0015] In step 32, it is determined whether a display stop request has been issued, indicating that the display of the advertisement requested by the advertiser or information including the advertisement should be stopped on the digital signage 4. This display stop request is issued in the electronic control unit 13, for example, when a preset date and time based on a contract with the advertiser is reached. If it is determined that this display stop request has not been issued, the process jumps to step 34. On the other hand, if it is determined that a display stop request has been issued, the process proceeds to step 33, where the display flag is reset to stop the display of the information including the advertisement on the digital signage 4. Next, the process proceeds to step 34.

[0016] In step 34, advertisements or information including advertisements requested by advertisers are of Digital Signage 4 to It is determined whether a display flag indicating that the content should be displayed is set. If it is determined that the display flag is set, the process proceeds to step 35, where the content to be displayed on the digital signage 4 is determined. At this time, for example, based on a contract with an advertiser, an advertisement to be displayed or information including an advertisement is determined as the content to be displayed on the digital signage 4. Next, in step 36, the content determined in step 35 is displayed on the digital signage 4.

[0017] On the other hand, if it is determined in step 34 that the display flag is not set, the process proceeds to step 37, where the display of the advertisement or information including the advertisement on the digital signage 4 is stopped. In this case, in one embodiment, the display on the digital signage 4 is completely stopped, and in another embodiment, the display content on the digital signage 4 is changed to content different from the advertisement or information including the advertisement. In either embodiment, the display of the advertisement or information including the advertisement on the digital signage 4 is stopped.

[0018] For example, in a tourist spot, if a digital signage-equipped vehicle 3 is traveling with an advertisement or information including an advertisement displayed on the digital signage 4, and a general vehicle 5 is traveling alongside the digital signage-equipped vehicle 3 as shown in FIG. 1 , the advertisement or the information display area including the advertisement will occupy a large space compared to the surrounding scenery as seen by the passengers of the general vehicle 5. As a result, the scenery as seen by the passengers of the general vehicle 5 will be spoiled. Therefore, in this embodiment, if the passengers feel that the advertisement or information including the advertisement displayed on the digital signage 4 is bothersome, the display of the advertisement or the information including the advertisement on the digital signage 4 can be stopped.

[0019] In this case, in the first embodiment of the present invention, a request to stop displaying advertisements or information including advertisements on the digital signage 4 is transmitted to the digital signage-equipped vehicle 3, thereby stopping the display of advertisements or information including advertisements on the digital signage 4. Of course, to be able to stop displaying advertisements or information including advertisements on the digital signage 4 in this way, it is necessary to obtain the consent of the advertiser in advance.

[0020] Next, an example of a procedure for making a request to the digital signage 4 will be described with reference to Fig. 5. As shown by A1 in Fig. 5, when it is desired to stop displaying an advertisement or information including an advertisement on the digital signage 4, a display stop request is transmitted from the vehicle 5 to the digital signage-equipped vehicle 3. When the communication device 23 of the digital signage-equipped vehicle 3 receives this display stop request, the display flag is reset in the digital signage display processing routine shown in Fig. 4, thereby stopping the display of the advertisement or information including the advertisement on the digital signage 4.

[0021] Next, as shown by A2 in Fig. 5, when it is desired to re-display an advertisement or information including an advertisement on the digital signage 4, a display request is transmitted from the vehicle 5 to the digital signage-equipped vehicle 3. When the communication device 23 of the digital signage-equipped vehicle 3 receives this display request, a display flag is set in the digital signage display processing routine shown in Fig. 4, whereby the content determined in step 35 is displayed on the digital signage 4.

[0022] In this case, a request can also be made to the digital signage 4 by the mobile terminal 8. In this case, at A1 in Fig. 5, a request to stop display is transmitted from the mobile terminal 8 to the digital signage-equipped vehicle 3, and at A2 in Fig. 5, a display request is transmitted from the mobile terminal 8 to the digital signage-equipped vehicle 3.

[0023] Next, another example of a procedure for making a request to the digital signage 4 will be described with reference to FIGS. 6A and 6B. In this example, a display stop request is made in the same manner as in the example shown in FIG. 5, but a display request is made in the same manner as in the example shown in FIG. 5. stop6A, when it is desired to stop displaying an advertisement or information including an advertisement on the digital signage 4, a display stop request is transmitted from the vehicle 5 or the mobile terminal 8 to the digital signage-equipped vehicle 3, as shown in B1. At this time, the display flag is reset in the digital signage display processing routine shown in FIG. 4, whereby the display of the advertisement or information including the advertisement on the digital signage 4 is stopped.

[0024] 6B shows the display processing executed in the electronic control unit 13 of the digital signage-equipped vehicle 3. Referring to FIG. 6B, in step 40, it is determined whether the display flag has been reset. If it is determined that the display flag has been reset, the process proceeds to step 41, where it is determined whether a certain time has elapsed since the display flag was reset. If it is determined that the certain time has elapsed, the process proceeds to step 42, where the display flag is set. If the display flag is set, the content determined in step 35 of FIG. 4 is displayed on the digital signage 4.

[0025] 1, as the distance between the digital signage-equipped vehicle 3 and the general vehicle 5 decreases, the proportion of the advertisement or information display area including the advertisement to the surrounding scenery increases when viewed from the passengers of the general vehicle 5. In this case, the shorter the distance between the digital signage-equipped vehicle 3 and the general vehicle 5, the greater the proportion of the advertisement or information display area including the advertisement to the surrounding scenery, and therefore the greater the degree to which the scenery is spoiled. Therefore, in a second embodiment of the present invention, the display of advertisements or information including advertisements on the digital signage 4 can be stopped only when the distance between the digital signage-equipped vehicle 3 and the general vehicle 5 is equal to or less than a certain distance.

[0026] 7 shows a processing routine for responding to a request to stop displaying the digital signage 4, which is executed in the electronic control unit 13 of the digital signage-equipped vehicle 3 in order to implement this second embodiment. In this second embodiment, when an occupant of a general vehicle 5 traveling around the digital signage-equipped vehicle 3 requests that the display of the digital signage 4 be stopped, the general vehicle 5 transmits to the digital signage-equipped vehicle 3 a request to stop displaying the digital signage 4 as well as information indicating the current location of the vehicle 5.

[0027] Referring to FIG. 7 , first, in step 50, it is determined whether a request to stop displaying the digital signage 4 transmitted from the general vehicle 5 has been received. If it is determined that a request to stop displaying the digital signage 4 has been received, then in step 51, the general vehicle 5 that transmitted the request to stop displaying the digital signage 4 is identified. Next, in step 52, a distance S from the digital signage-equipped vehicle 3 to the general vehicle 5 that transmitted the request to stop displaying the digital signage 4 is calculated based on the transmitted information indicating the current location of the vehicle 5 and the current location of the digital signage-equipped vehicle 3. Next, in step 53, it is determined whether the calculated distance S is shorter than a reference distance S0, for example, 30 meters. If it is determined that the calculated distance S is shorter than the reference distance S0, then the process proceeds to step 54, where the request to stop displaying the digital signage 4 is accepted. On the other hand, if it is determined that the calculated distance S is longer than the reference distance S0, then the process proceeds to step 55, where the request to stop displaying the digital signage 4 is rejected. When the request to stop display on the digital signage 4 is accepted, the display flag is reset in the digital signage display processing routine shown in FIG. 4, thereby stopping the display of advertisements or information including advertisements on the digital signage 4.

[0028] Next, a third embodiment will be described in which the display of advertisements or information including advertisements on the digital signage 4 is stopped when a request to stop displaying the digital signage 4 is received from the general vehicle 5 traveling closest to the digital signage-equipped vehicle 3. FIG. 8 shows a processing routine for responding to a request to stop displaying the digital signage 4 that is executed in the electronic control unit 13 of the digital signage-equipped vehicle 3 to implement this third embodiment. Note that in this third embodiment as well, when an occupant of a general vehicle 5 traveling around the digital signage-equipped vehicle 3 requests that the display of the digital signage 4 be stopped, the vehicle 5 transmits to the digital signage-equipped vehicle 3 the request to stop displaying the digital signage 4 as well as information indicating the current location of the vehicle 5.

[0029] 8, first, in step 60, it is determined whether a request to stop displaying the digital signage 4 transmitted from the general vehicle 5 has been received. If it is determined that a request to stop displaying the digital signage 4 has been received, in step 61, the general vehicle 5 that transmitted the request to stop displaying the digital signage 4 is identified. Next, in step 62, the distance from the digital signage-equipped vehicle 3 to the general vehicle 5 that transmitted the request to stop displaying the digital signage 4 is calculated based on the transmitted information indicating the current position of the vehicle 5 and the current position of the digital signage-equipped vehicle 3. Next, in step 63, the distance from the digital signage-equipped vehicle 3 to other vehicles traveling around the digital signage-equipped vehicle 3 is calculated based on, for example, detection results from a LIDAR provided in the digital signage-equipped vehicle 3.

[0030] Next, in step 64, it is determined whether the vehicle 5 that transmitted the request to stop displaying the digital signage 4 is located closest to the digital signage-equipped vehicle 3 among the vehicles traveling around the digital signage-equipped vehicle 3. If it is determined that the vehicle 5 that transmitted the request to stop displaying the digital signage 4 is located closest to the digital signage-equipped vehicle 3, the process proceeds to step 65, where the request to stop displaying the digital signage 4 is accepted. In contrast, if it is determined that the vehicle 5 that transmitted the request to stop displaying the digital signage 4 is not located closest to the digital signage-equipped vehicle 3, the process proceeds to step 66, where the request to stop displaying the digital signage 4 is rejected. If the request to stop displaying the digital signage 4 is accepted, the display flag is reset in the digital signage display processing routine shown in FIG. 4, whereby the display of advertisements or information including advertisements on the digital signage 4 is stopped.

[0031] Next, a fourth embodiment will be described in which, for example, an advertising display restricted area is set in which advertising display is restricted so as not to spoil the scenery, and when the digital signage-equipped vehicle 3 travels through the advertising display restricted area, the display of the digital signage 4 is stopped. Fig. 9 shows a display control routine for the digital signage 4 executed in the electronic control unit 10 of the digital signage-equipped vehicle 3 to implement this fourth embodiment. Note that this display control routine for the digital signage 4 can also be executed in the management server 6, in which case a request to stop displaying the digital signage 4 is issued from the management server 6.

[0032] Referring to FIG. 9, first, in step 70, the current location of the digital signage-equipped vehicle 3 is acquired. Next, in step 71, it is determined whether the digital signage-equipped vehicle 3 is currently traveling in an advertisement display restricted area. If it is determined that the digital signage-equipped vehicle 3 is not currently traveling in an advertisement display restricted area, the process proceeds to step 72, where a display flag in the digital signage display processing routine shown in FIG. 4 is set. As a result, an advertisement or information including an advertisement is displayed on the digital signage 4. On the other hand, if it is determined that the digital signage-equipped vehicle 3 is currently traveling in an advertisement display restricted area, the process proceeds to step 73, where a display flag in the digital signage display processing routine shown in FIG. 4 is reset. As a result, the display of the advertisement or information including an advertisement on the digital signage 4 is stopped.

[0033] As described above, when the display of an advertisement or information including an advertisement on the digital signage 4 is stopped in step 37 of the digital signage display processing routine shown in Fig. 4, in one embodiment, the display on the digital signage 4 is completely stopped, and in another embodiment, the display content on the digital signage 4 is changed to content different from the advertisement or the information including an advertisement. Fig. 10 shows a routine for changing the display content of the digital signage 4 executed in the electronic control unit 10 of the digital signage-equipped vehicle 3 when the display content on the digital signage 4 is changed to content different from the advertisement or the information including an advertisement.

[0034] 10 , first, in step 80, the current position of the digital signage-equipped vehicle 3 and the current position of the general vehicle 5 that sent the request to stop displaying the digital signage 4 are acquired. In this case, the current position of the general vehicle 5 that sent the request to stop displaying the digital signage 4 is detected based on, for example, a detection signal from a lidar (LIDAR) provided in the digital signage-equipped vehicle 3 and images captured by a front camera, a side camera, and a rear camera. Next, in step 81, based on the positional relationship between the current position of the digital signage-equipped vehicle 3 and the current position of the general vehicle 5 that sent the request to stop displaying the digital signage 4, a direction G ( FIG. 1 ) passing through the eyes of the occupant of the general vehicle 5 and the center H ( FIG. 1 ) of the digital signage 4, i.e., a direction G toward the center of the portion of the view obstructed by the digital signage 4 as seen by the occupant of the general vehicle 5, is calculated.

[0035] Next, in step 82, the optical axis of the camera 9 mounted on the digital signage-equipped vehicle 3 is adjusted to the direction G calculated in step 81. Next, in step 83, an image captured by the camera 9 is acquired, and the dimensions of the image are adjusted, for example, so that the image appears the same as what would actually be seen by an occupant of the general vehicle 5. Next, in step 84, the adjusted image is displayed on the digital signage 4. In this case, if a traffic sign such as a traffic light is present in the image captured by the camera 9, it is also possible to display only the traffic sign on the advertising display on the digital signage 4.

[0036] It is also possible to store a history of requests received from general vehicles 5 to stop displaying the digital signage 4, and periodically transmit this stored history of requests to advertisers.

[0037] Thus, in this embodiment by Tatsumi, the vehicle 3 equipped with the digital signage 4 is equipped with a communication device 23 for communicating with the outside, and when information including advertisements is displayed on the digital signage 4, and a request to stop displaying information including advertisements on the digital signage 4 is received from another vehicle 5, management server 6 or mobile terminal 8 around the vehicle 3, the display of information including advertisements on the digital signage 4 is stopped.
