The current location detection unit 26 realizes a function of detecting the current location (latitude / longitude) of the vehicle 100 with a known configuration. The map database 27 is configured as a database that records digital map data associated with latitude / longitude information.

  The navigation device 25 is provided with a known navigation function for guiding the host vehicle 100 to the destination. In the present embodiment, the navigation function is implemented by the control unit 10 in order to simplify the description. It will be described as being done. Further, a description will be given assuming that the navigation processing described later is also performed by the control unit 10. However, the navigation process may be performed in the navigation device 25.

  The display 31 is disposed at a plurality of arbitrary locations around the host vehicle 100. For example, as shown in FIG. 2, the display 31 is arranged as a rear display 31 a behind the host vehicle 100, and also as side displays 31 b and 31 c on the side of the host vehicle 100 as shown in FIG. 3. Be placed.

  Each of the displays 31 employs a transmissive organic EL display, and the side displays 31b and 31c are also arranged on the window glass. The transmissive organic EL display can be arranged to provide a display image without obstructing the view from the inside of the host vehicle 100.

  A large number of directional speakers 32 are provided on the outer periphery of the host vehicle 100 and are configured to be able to transmit sound waves in any direction by adjusting the amplitude and phase by the control unit 10. In addition, the directional speaker 32 transmits a high-volume sound wave only to a specific place (a place where a specific person is present) by adjusting the resonance positions of sound waves output from the plurality of speakers by the control unit 10. You can also

  The all-around camera 33 is configured as a plurality of cameras arranged in at least four locations on the outer periphery of the host vehicle 100. The all-around camera 33 images the entire area around the host vehicle 100 using the plurality of cameras.

  The microphones 34 are configured as a plurality of microphones that are arranged at least in two locations, the interior of the host vehicle 100 and the exterior of the interior of the vehicle. The microphone 34 collects voice and noise emitted by the driver of the host vehicle 100.

  The short-range communication unit 35 performs short-range communication that limits the line-of-sight range, for example, by performing communication using infrared communication or wireless LAN. Examples of communication partners of the short-range communication unit 35 include a portable terminal 51 and another vehicle 61. The mobile terminal 51 and the other vehicle 61 are configured to be connectable to the Internet network 43 via a base station such as the base station 42.

  The control unit 10 is configured as a computer including a CPU 11 and a memory 12 such as a ROM and a RAM. The CPU 11 executes various processes such as an advertisement display process, which will be described later, according to the program recorded in the memory 12.

  The advertisement display system 1 includes base stations 41 and 42 and a server 45 in addition to the configuration mounted on the host vehicle 100. The base stations 41 and 42 are configured as well-known wireless communication base stations of mobile phone companies.

  The server 45 includes an advertisement information database 46. Information about a large number of advertisements is stored in the advertisement information database 46, and information such as distribution location, advertisement fee, target person, advertisement content, display spec allowable range, and the like is associated with each advertisement. In addition to the well-known server function, the server 45 selects one or a plurality of pieces of advertisement information stored in the advertisement information database 46 in response to a request from the control unit 10 and sends the selected information to the control unit 10 It has.

[Advertising display processing]
In the advertisement display system 1 configured as described above, the control unit 10 performs an advertisement display process shown in FIG. The advertisement display process is a process of acquiring an advertisement optimal for the host vehicle 100 from the server 45 and displaying it on the display 31. Further, the advertisement display process is a process that starts when, for example, the vehicle 100 is turned on, and is then repeatedly performed at regular intervals (for example, 50 ms).

  In the advertisement display process, as shown in FIG. 4, first, an image captured by the omnidirectional camera 33 is acquired (S110). Then, own vehicle position information is acquired (S120). Note that the current location obtained by the navigation device 25 can be used as the vehicle position information.

  Subsequently, by performing image processing on the captured image, the gender and age of the person existing in the captured image are estimated (S130). Note that the process of estimating the gender and age of a person can be realized using well-known techniques such as a technique relating to face authentication and a technique for estimating gender and age based on how the skin of the face hangs down.

  Subsequently, the display 31 to be displayed is selected according to the direction of the person in the captured image (S140). In this processing, the display closest to the direction of the person among the plurality of displays 31 is set as the display for the person.

  Subsequently, a request for advertisement information is transmitted to the server 45 (S150). In this process, as a request for advertisement information, information including the current value (position information) of the host vehicle 10, person information, and display specifications is transmitted to the server 45 for each display 31.

  Here, the person information includes information on the gender and age of the person and information on the number of persons. The display spec includes information on the size (resolution) of the display and the number of colors that can be used.

  When the server 45 receives such a request for advertisement information, the server 45 selects advertisement information corresponding to the current location of the vehicle 100, personal information, display specifications, etc., from the advertisement information recorded in the advertisement information database 46. The advertisement information is returned to the host vehicle 100. The advertisement information includes image data displayed on the display 31 and audio data corresponding to the image.

  Note that a large amount of advertisement information is recorded in the advertisement information database 46, and the server 45 selects a combination of advertisements having the highest advertisement charge among the displayable advertisements. The server 45 monitors display information such as the number of advertisements displayed and display time, and a fee corresponding to the display information is paid to the owner (user) of the host vehicle 100.

  Subsequently, the control unit 10 acquires the advertisement information transmitted from the server 45 (S160). Then, the restriction process (S170) and the output process (S180) are performed in order, and when these processes are finished, the advertisement display process is finished.

  Here, the restriction process is a process for setting to restrict (prohibit) the display of the advertisement on the display 31 when the vehicle condition matches a certain condition. In the restriction process, as shown in FIG. 5, first, vehicle information of the host vehicle 100 is acquired (S210).

  Here, the vehicle information is, for example, information indicating whether or not the host vehicle 100 is traveling, vehicle speed, a front vehicle that travels in front of the host vehicle 100, and a rear vehicle that travels behind the host vehicle 100. Indicates the distance between vehicles. In the process of this embodiment, information including the vehicle speed is acquired as vehicle information.

  Then, based on the acquired vehicle information, it is determined whether the own vehicle 100 is traveling (S220). If the host vehicle 100 is traveling (S220: YES), the advertisement display on the rear display 31a is set to be restricted (S230), and the restriction process is terminated. Further, if the host vehicle 100 is not traveling, such as when the vehicle is stopped (S220: NO), the restriction process is terminated.

  Next, the output process is a process of transmitting advertisements and other information from the display 31 and the directional speaker 32. Specifically, as shown in FIG. 6, in the output process, first, the direction of a person based on the image captured by the all-around camera 33 is acquired (S310), and noise outside the vehicle is detected using the microphone 34 outside the vehicle (S320). ).

  Subsequently, a noise cancellation signal for this noise is generated (S330). That is, a signal for outputting a sound wave having an opposite phase of noise is generated. Subsequently, the noise cancellation signal is synthesized with an audio signal included in the advertisement information (S340), and a sound wave based on the synthesized signal is output toward the person (S350).

  Subsequently, an advertisement image included in the advertisement information is displayed on the display 31 excluding the display that is restricted from being displayed (S360). Subsequently, it is determined whether or not the brake of the host vehicle 100 and the direction indicator (not shown) are activated (S370). In this process, the operating state of the brake and the direction indicator is acquired through, for example, the in-vehicle network, and determination based on the acquired operating state is performed.

If the brake and the direction indicator are not operating (S370: NO), it is determined whether or not there are other precautions (S380). Here, examples of other notes include the following.
[1] A social or physical weak person such as a child is on the own vehicle 100 [2] A crossing person is in the vicinity [3] An automatic driving is in progress [4] Navigation information of a rear vehicle [ 5] Start or End of Vehicle Group Traveling When navigation information of the rear vehicle is adopted as caution information, an image to be displayed on the navigation device from the rear vehicle in this process is acquired via the short-range communication unit 35. .

  Further, the vehicle group traveling refers to a form in which a plurality of vehicles automatically travel together. In this vehicle group traveling, the vehicle group traveling may change from manual traveling to automatic traveling when joining the vehicle group traveling, and may transition from automatic traveling to manual traveling when leaving the vehicle group traveling. For this reason, each vehicle notifies other vehicles using near field communication when starting or ending the vehicle group traveling. When receiving the notification, the host vehicle 100 recognizes the start or end of the vehicle group traveling.

  If there are other cautions (S380: YES), or if the brake or the direction indicator is activated in the process of S370 (S370: YES), a caution image is displayed on the rear display 31a (S390). .

Here, the caution image represents an image that calls attention to the driver of the vehicle behind. Specific examples include the following.
[1] To actuate brakes and direction indicators (brake attention, etc.)
[2] There is a weak person such as a child (a child is riding, etc.)
[3] To the effect that there are crossers (Pedestrian crossing caution)
[4] The fact that automatic operation is in progress (during automatic operation)
[5] Rear vehicle navigation information (100m ahead right turn etc.)
[6] Start or end of vehicle group driving (Some vehicles start or end vehicle group driving)
When displaying such an image, the display 31 may be turned on or blinked so that it also serves as a direction indicator and a brake light. When such processing ends, the output processing ends.

  If there are no other precautions in the process of S380 (S380: NO), the advertisement display time is compared with a preset time that is a preset threshold value (S410). Here, the advertisement display time represents the time after the display is switched from the image other than the advertisement (including the case where nothing is displayed) to the advertisement. The set time represents a time for suppressing a person who sees the advertisement from getting tired of the advertisement and seeing the display, and is set to a time when a person is statistically bored of the advertisement.

If the advertisement display time exceeds the set time (S410: YES), useful information is acquired (S420). Here, examples of useful information include the following.
[1] Railway operation information (mainly displayed on the side displays 31b, 31c, etc. other than the rear)
[2] Traffic information (mainly displayed on the rear display 31a)
[3] Weather information (displayed on all displays 31)
[4] Front vehicle image (mainly displayed on the rear display 31a)
Note that the forward vehicle image indicates an image or the like in which the forward vehicle images a further forward of the forward vehicle, and this image is received via the short-range communication unit 35.

  Subsequently, any of the acquired useful information set in advance is displayed on the predetermined display 31 (S430). In this process, the type of image to be displayed (traffic information, weather information, etc.) may be rotated in a preset order.

When such processing ends, the output processing ends. Further, in the process of S410, the output process is also ended when the advertisement display time is equal to or shorter than the set time (S410: NO).
[Modified example of advertisement display processing (restriction processing)]
In the above embodiment, when the rear vehicle performs automatic driving or semi-automatic traveling that automatically accelerates or decelerates following the preceding vehicle, the limiting process executed by the control unit 10 is, for example, a modification shown in FIG. It can also be set as a restriction process. In the modification process of the modified example, as shown in FIG. 7, first, vehicle information is acquired (S510).

  In the process of acquiring vehicle information in the present modification, information on the vehicle speed and the inter-vehicle distance to the preceding vehicle traveling in front of the host vehicle 100 is also acquired. In this process, the position of the other vehicle 61 and information on whether or not the vehicle 61 is in automatic operation (including semi-automatic operation) are also transmitted from the other vehicle 61 around the host vehicle 100 via the short-range communication unit 35. get.

  Subsequently, it is determined whether or not the rear vehicle among the other vehicles 61 is in an automatic driving (S520). In this process, it is determined whether or not the other vehicle 61 corresponds to the rear vehicle based on the positions of the host vehicle 100 and the other vehicle 61, and whether or not the other vehicle 61 corresponding to the rear vehicle is in automatic driving. Determine.

  If the vehicle behind is in automatic driving (S520: YES), the restriction process is terminated. That is, when the rear vehicle is in automatic driving, even if an image is displayed behind the host vehicle 100, since the probability that the host vehicle 100 will collide with the rear vehicle is low, display of an advertisement or the like is permitted.

  Subsequently, the process of S220 is performed. If an affirmative determination is made in this process, the inter-vehicle distance to the preceding vehicle is compared with a preset reference distance (S530). Here, the reference distance is set to a distance at which the rear vehicle should prepare for braking, and is set using at least one of the vehicle speed and the relative speed, for example. More specifically, the reference distance is set to a larger value, for example, as the vehicle speed increases and as the relative speed (only when the rear vehicle is faster than the host vehicle 100) increases.

  If the inter-vehicle distance is greater than the reference distance (S530: YES), the restriction process is terminated. That is, when the inter-vehicle distance from the rear vehicle is relatively large, since the probability that the own vehicle 100 will collide with the rear vehicle is low, display of advertisements and the like is permitted.

If the inter-vehicle distance is equal to or less than the reference distance (S530: NO), the process proceeds to S230.
Even if it does in this way, the effect similar to the said embodiment can be acquired.

[Bookmark processing]
In the advertisement display system 1 described above, bookmark processing is performed for bookmarking advertisements viewed by surrounding persons using the mobile terminal 51 possessed by the persons. The bookmark process in the mobile terminal 51 is a process in which the mobile terminal 51 receives information on an advertisement to be bookmarked by the user of the mobile terminal 51 from the vehicle displaying the advertisement and saves it. The bookmark process in the portable terminal 51 is started when, for example, an operation (such as pressing a button) for bookmarking an advertisement is performed on the portable terminal 51.

  In the bookmark processing in the portable terminal 51, as shown in the left column of FIG. 8, first, a request signal including its own position and a bookmark request is transmitted using short-range communication (S610). In this process, a request signal is transmitted to an unspecified number of short-range communication units 35 included in the host vehicle 100, the other vehicle 61, and the like.

  On the other hand, a vehicle such as the host vehicle 100 or the other vehicle 61 (in the case of the host vehicle 100, the control unit 10) performs bookmark processing shown in the right column of FIG. The bookmark processing in the vehicle is processing for receiving a bookmark request from the mobile terminal 51 and returning advertisement information corresponding to the request to the mobile terminal 51 when the request is a bookmark request for an advertisement displayed by the mobile terminal 51. The bookmark process in the vehicle is, for example, a process that is started when the vehicle is turned on and is repeatedly performed at predetermined intervals (for example, 50 ms).

  In the bookmark processing in the vehicle, as shown in the right column of FIG. 8, first, it is determined whether or not there is a bookmark request from the portable terminal 51 (S710). That is, in the bookmark process in the portable terminal 51, it is determined whether or not a request signal corresponding to the process of S610 has been performed.

  If there is no bookmark request (S710: NO), the processing of S710 is repeated. If there is a bookmark request (S710: YES), it is determined whether the position of the mobile terminal 51 is within the advertisement display area from the host vehicle (S720).

  Here, the advertisement display area indicates a distance range (for example, a range within 30 m) set in advance for each display 31 as an area where the advertisement can be appropriately visually recognized. In the present embodiment, this advertisement display area is set so as to substantially coincide with the voice transmission range in which voice is transmitted using the directional speaker 32.

  If the position of the portable terminal 51 is not within the advertisement display area (S720: NO), the bookmark process in the vehicle is terminated as a bookmark request for the advertisement displayed by the mobile terminal 51 itself. If the position of the portable terminal 51 is within the advertisement display area (S720: YES), the advertisement for which the bookmark request has been made is specified (S730).

  In this process, based on the position information of the mobile terminal 51, which display 31 of the plurality of displays 31 is specified is specified. Further, in this process, each display 31 is based on the time when the request is received from the mobile terminal 51 at the time of request (slightly before the time when the request is received in consideration of the time required for operating the mobile terminal 51). Identify the ads that were showing on. And the advertisement which received the request | requirement based on the specified display 31 and time is specified as one.

  Subsequently, the advertisement information to which the URL (homepage address), photo, etc. of the identified advertisement is attached is transmitted to the requesting mobile terminal 51 (S740). Here, the advertisement information transmitted from the vehicle may be newly acquired from the server 45 by receiving a request signal, or may be acquired when acquiring data for display from the server 45. .

When such a process ends, the bookmark process in the vehicle ends.
In the bookmark process in the portable terminal 51, it is determined whether or not the advertisement information has been received following the process of S610 (S620). This process is affirmed when the advertisement information transmitted in the process of S740 of the bookmark process in the vehicle is received.

  If the advertisement information has not been received (S620: NO), the process of S620 is repeated. If advertisement information has been received (S620: YES), the received advertisement information is stored in its own memory (S630), and the bookmark process in the portable terminal 51 is terminated.

In addition, the user of the portable terminal 51 can access a homepage showing the details of the advertisement from the advertisement information stored in the portable terminal 51, and can obtain necessary information.
[Modification of Display 31 Configuration]
In the above embodiment, the display 31 is disposed on the body of the vehicle (the host vehicle 100). However, the display 31 may be disposed in any manner as long as the display 31 can be recognized from the outside of the vehicle. In the example shown in FIG. 9, in a wagon type vehicle 101, a member including a solar panel unit 36 and a display 31 d is placed on a general base carrier 37. The member provided with the solar panel 36 and the display 31d is fixed to the base carrier 37 using a known fixing member such as a bolt.

  The solar panel unit 36 includes a solar panel with a power generation surface receiving power and generating power upward, and sends the electric power obtained by the power generation to the vehicle 101 via a cable (not shown). This electric power can be used not only for charging a battery mounted on the vehicle 101 but also as a power source for the display 31d.

  The display 31 d is connected to the left and right end portions of the solar panel portion 36. As shown in FIG. 10, the display 31 d is set so that the display content of the display 31 d can be viewed when the vehicle 101 is viewed from the side of the vehicle 101.

  In such a vehicle 101, the display 31 can be retrofitted even if the vehicle 101 does not include the display 31 at the time of delivery. In order to retrofit the display 31, for example, it may be configured as shown in FIG.

  That is, in the vehicle 102, as shown in FIG. 11, the display 31g is arranged in the space between the rear glass 38 and the rear seat 39. The image displayed on the display 31g is seen from behind the vehicle 102 through the rear glass 38.

  In this way, even if the vehicle 102 does not have the display 31 at the time of delivery, the display 31 can be retrofitted. Moreover, in this structure, since the display 31g is arrange | positioned in the vicinity of the rear glass 38, it can suppress that the rear glass 38 is fogged with the heat | fever emitted from the display 31g.

  Furthermore, the display 31 may be used for combining a plurality of displays 31 to form one advertisement. For example, as illustrated in FIG. 12, when a plurality of vehicles 103 and 104 are stopped or running side by side, a rear display 31 e disposed on the vehicle 103 and a rear display 31 f disposed on the vehicle 104 are used. A plurality of images related to one advertisement are respectively displayed.

  Specifically, when the server 45 recognizes the positional relationship of each vehicle using the position information received from the plurality of vehicles 103 and 104, and the plurality of vehicles are arranged in the front-rear and left-right directions, Advertisement information including an image forming one advertisement with a plurality of images is transmitted to each of the vehicles 103 and 104. In the example shown in FIG. 12, an advertisement for “XX ice” and an ice cream is displayed on the vehicle 103 on the left side, and the store “XX ice” is opened on the right vehicle 104, such as “← store opening sale”. Is displayed.

When one related advertisement is displayed using a plurality of vehicles in this way, a larger space constituted by the plurality of vehicles can be used as a display.
Moreover, you may display images, such as an advertisement and attention according to the lane where the vehicles 103 and 104 are stopping.

[Navigation process]
Furthermore, the advertisement display system 1 described above is configured to be able to carry out route setting in consideration of economics when traveling from the travel distance (fuel cost), toll road fee, time, advertisement revenue, etc. to the destination. . Further, when the user selects a route, the necessary cost including the advertising revenue to the destination is displayed on the display unit (display of the navigation device or the like).

  Specifically, the control unit 10 performs the navigation process shown in FIG. The navigation process is a process that is started when the navigation function is activated, for example. In the navigation process, as shown in FIG. 13, it is first determined whether or not a destination has been set (S810).

  If the destination is not set (S810: NO), the process of S810 is repeated. If a destination is set (S810: YES), a plurality of routes to the destination are extracted, and advertisement information to be displayed is acquired for each of these routes (S820).

  Here, the sponsor who requests the display of the advertisement sets the display range of the advertisement and the advertisement fee. For example, as shown in FIG. 14, the advertisement fee is set for each area (displayed by a broken line circle). ing. For example, when the advertisement is changed according to the gender or age of the target person, the average price or the median value is adopted, and when the price changes depending on the number of times of display, the size of the area ( Adopt a fee based on the average number of impressions according to the length of the route in the area.

  The advertising information to be displayed includes an advertising fee corresponding to the route. For example, in the route [A] shown in FIG. 14, since the advertisement fee passes through the area of 300 yen, the advertisement fee is 500 yen, and the advertisement fee is 100 yen, the total advertisement fee is 900 yen. . In addition, in the route [B], since the advertisement fee passes through three areas where the advertisement fee is 100 yen and passes through one area where the advertisement fee is 200 yen, the total advertisement fee is 500 yen.

  Subsequently, a fuel cost for traveling along each route and a toll road fee are acquired (S830). As for the fuel cost, the distance of the route, the fuel unit price set in advance, and the fuel consumption information of the host vehicle 100 (the fuel consumption obtained from the fuel consumption meter in the case where a fuel consumption meter is provided in advance) are used. Calculate. Further, the toll road fee is acquired from the map database 27 or the like.

  Subsequently, the charge setting for the time loss is acquired (S840). The charge setting for the time loss indicates a charge unit price when the time is converted into a charge. The fee setting for the time loss is set, for example, such that the time loss on the route that can travel in the shortest time is 0, and the extra time required other than this route is 1000 yen per hour.

  Here, the advertising fee tends to be set higher in the vicinity of a station where there are many pedestrians and in a busy street where there are many signals. On the other hand, in a place where the advertising fee is high, the traveling speed of the host vehicle 100 is slow, and time loss is likely to occur. For this reason, in this embodiment, in order to optimize the balance between the advertising fee revenue and the time loss, the economics of the respective routes can be compared by converting the time into a fee.

  Subsequently, the expense of each route is calculated and displayed on the display unit (S850). That is, as shown in FIG. 14, the total amount of fuel cost, toll road fee, time loss, and advertising revenue (displayed in minus) when traveling along each route is calculated and displayed. Note that calculation or display of one or more charges excluding advertising revenue can be omitted.

  Subsequently, it is determined whether or not the user has selected one of a plurality of routes (S860). If one of the routes has not been selected (S860: NO), the process returns to S860. If one of the routes has been selected (S860: YES), a process of guiding the host vehicle 100 to the destination according to this route is started (S870), and the navigation process is terminated.

In the process of S860, a route with the best economic efficiency may be set without waiting for selection by the user.
[Variation in which the display 31 is a head-up display]
In the above embodiment, the example in which the image of the display 31 is displayed outside the host vehicle 100 has been described. However, the display 31 may be arranged inside the host vehicle 100 toward the passenger. In this case, for example, a display such as the navigation device 25 may be a display for displaying an advertisement.

  Moreover, you may make it show in FIG. 15 and FIG. That is, in the vehicle 106, as shown in FIG. 15, instead of the above-described rear display 13a, a sheet 65 having a uniform color such as green or blue is disposed. A vehicle 107 traveling behind the vehicle 106 includes a display 13h configured as a head-up display on the windshield.

  Then, in the vehicle 107, the sheet 65 is searched from the image captured by the all-around camera 33, and as shown in FIG. 16, an advertisement image or the like is displayed on the head-up display 13h so as to overlap the position of the sheet 65.

In this way, when viewed from the vehicle 107, an advertisement can be displayed in the same manner as when the rear display 13a is arranged on the vehicle 106.
