It may be constructed by a general-purpose computer such as C (Personal Computer) or a dedicated computer. The present invention does not limit the hardware configuration of the distribution server 7.

  The distribution server 7 implements each processing unit shown in FIG. 4 by executing the application program stored in the storage unit 43 by the control unit 45. As such a processing unit, the distribution server 7 includes a data management unit 76, a vehicle information reception unit 77, a distribution data extraction unit 78, a distribution unit 79, a privilege determination unit 80, and the like. As a database referred to by these processing units, the storage unit 43 stores a vehicle registration information table 71, a distribution data information table 72, a condition weight table 73, content data, a distribution number table 74, and a privilege table 75. Hereinafter, each processing unit of the distribution server 7 will be described.

  The data management unit 76 manages a vehicle registration information table 71, a distribution data information table 72, a condition weight table 73, content data, a distribution count table 74, and a privilege table 75. The data management unit 76 updates data in each database, extracts data from each database, and the like in response to requests. For example, the data management unit 76 provides a user interface for updating the vehicle registration information table 71, the distribution data information table 72, the condition weight table 73, the distribution number table 74, and the privilege table 75 as a system administrator, a vehicle owner, and the like. To provide vehicle registration information.

  Further, the data management unit 76 may provide a user interface for registering or deleting content data to the system administrator, the vehicle owner, and the like. The data management unit 76 may automatically receive the content data from another server device or the like and store it in the storage unit 43.

  FIG. 5 is a diagram illustrating an example of a vehicle registration information table. The vehicle registration information table 71 stores the vehicle ID, manufacturer, vehicle type, vehicle color, model year, and medium area for each vehicle. Among these, the medium area field stores data indicating the area of the display surface of the display device 5 mounted on the vehicle 3.

  The content data stored in the storage unit 43 and distributed from the distribution server 7 includes data indicating advertisements, news, weather information, disaster information, and the like. This data may be image data such as still image data or moving image data, or may be text data. The present invention does not limit the format, content, etc. of content data handled by such a content distribution system.

  Since the content data stored in the storage unit 43 is displayed on the display device 5 of the vehicle 3 as described above, a part of the vehicle 3 can be used as an advertising medium according to the present embodiment. However, if the content to be handled is only an advertisement, there is a possibility that the viewer's interest will be attracted and the attention level cannot be raised, and the value as an advertising medium may be reduced. Therefore, it is desirable to include information that is likely to attract the viewer's interest, such as news, weather information, and disaster information. Thus, by targeting various types of content, the medium value of the display device 5 itself of the vehicle 3 can be increased.

  FIG. 6 is a diagram illustrating an example of the distribution data information table 72. In the distribution data information table 72, for each content data stored in the storage unit 43, an information ID for identifying the content, a content data address indicating an address where the content data is stored, and the content to be distributed Various types of information used as distribution conditions for selection as are stored.

  The content type field stores information such as an advertisement indicating the type of the content, weather information, disaster information, and the like. In the price field, the price when the advertising content is to be distributed is stored. The provider of the advertisement content can register the advertisement content in the distribution server 7 by paying the price set in this price field. As will be described later, content with a higher price set in this price field is preferentially distributed, so that the provider of the advertisement content sets a higher price. Thereby, according to this embodiment, the auction site of advertisement content registration can be provided.

  The various information includes medium area, manufacturer, vehicle type, vehicle color, year, time, place, speed, temperature, humidity, and destination. The content provider can set delivery conditions for the content by setting necessary conditions for each of the various types of information. According to the example of FIG. 6, the content with the information ID 29549 has a display surface with a medium area of 100 × 100 or more, is located at a certain intersection in Shibuya Ward, and has a speed of 30 km / h to 60 km / h. Distribution conditions are set such that the content is distributed to a vehicle 3 that is running, has an outside air temperature of 26 ° C. or more, and a humidity of 40% or more. Note that * in FIG. 6 indicates that no condition is set for the information.

  FIG. 7 is a diagram illustrating an example of the condition weight table 73. The condition weight table 73 stores weight values of various information used as distribution conditions of the distribution data information table 72. This weight value is a value used to determine the distribution priority of each content. Information with a larger weight value is information that is regarded as important in determining the priority of distribution. The price weight value is applied to a record that is set to the highest price included in the distribution data information.

According to the example of FIG. 7, the content whose content type indicates disaster information (weight value = 1000000) is most preferentially distributed, and the medium area (weight value = 10000) is regarded as important as other information. Yes. Even if the weight value of disaster information is set to a large value, the content indicating disaster information is a special event, and it is unlikely that the content information is registered. There is no problem of being displayed.

  The vehicle information receiving unit 77 receives the content request packet from the vehicle 3 received via the communication unit 41, and acquires the vehicle ID and vehicle environment information included in the received content request packet. The vehicle information reception unit 77 includes the reception time of the content request packet in the vehicle environment information, and sends the vehicle ID and vehicle environment information to the distribution data extraction unit 78.

  The distribution data extraction unit 78 extracts the vehicle registration information of the vehicle ID from the vehicle registration information table 71 by specifying the vehicle ID sent from the vehicle information reception unit 77. The distribution data extraction unit 78 specifies at least one distribution from the distribution data information table 72 by specifying the vehicle registration information extracted from the vehicle registration information table 71 and the vehicle environment information sent from the vehicle information reception unit 77. Extract records that meet the conditions. Similarly, the distribution data extraction unit 78 extracts data from the condition weight table 73.

The distribution data extraction part 78 acquires the record extracted from the distribution data information table 72, and inspects whether the vehicle registration information and the vehicle environment information satisfy each distribution condition for each record. The distribution data extraction unit 78 adds up the weight values of information satisfying the distribution conditions for each record. The sum of the weight values indicates the distribution priority of the content. The distribution data extraction unit 78 selects a predetermined number of records from the records having a large total weight value of each record, and is included in each selected record among the plurality of content data stored in the storage unit 43. Each content data is extracted from the content data address.

  If the predetermined number of records is 1, for example, only content data having the largest weight value (priority) is extracted. For example, when the requested content number is included in the content request packet sent from the vehicle 3, the requested content number may be set to the predetermined number of records. The distribution data extraction unit 78 sends the vehicle ID sent from the vehicle information reception unit 77, the content data extracted in this way, and its information ID to the distribution unit 79.

  The distribution unit 79 transmits the content data sent from the distribution data extraction unit 78 to the vehicle 3 specified by the vehicle ID that is the transmission source of the content request packet via the communication unit 41. When a plurality of pieces of content data are requested, the contents may be transmitted in order from the contents with the highest priority, or the priorities may be transmitted together with the contents data.

  When the distribution unit 79 finishes distributing the content data, the distribution unit 79 updates the number of distributions of the content data for the distribution destination vehicle 3 in the distribution number table 74. FIG. 8 is a diagram illustrating an example of the distribution number table 74. The distribution number table 74 stores the number of distributions for each vehicle ID with respect to the information ID indicating each content data.

  The privilege determination unit 80 determines a privilege to the vehicle 3 according to the number of times content is distributed at a predetermined cycle and a predetermined timing. Specifically, for each information ID stored in the distribution table 74, the privilege determination unit 80 calculates the total number of distributions, which is the total number of distributions for each vehicle ID. The privilege determination unit 80 obtains a reducible price (for example, 40% of the price) out of the prices of the distribution data record specified by each information ID in the distribution data information table 72, and calculates the reducible price as described above. The amount divided by the total number of distributions is set as a unit privilege price, and the privilege price provided to each vehicle 3 is determined based on the unit privilege price and the number of distributions of each vehicle ID.

  For advertising content A with a price of 1 million yen (reducible rate 40%), vehicle X receives 5 distributions, vehicle Y receives 2 distributions, and vehicle Z receives 1 distribution. The special price for X is determined to be 250,000 yen (= 1 million yen x 0.4 ÷ 8 x 5), and the special price for vehicle Y is determined to be 100,000 yen (= 1 million yen x 0.4 ÷ 8 x 2). The privilege price of Z is determined to be 50,000 yen (= 1 million yen x 0.4 ÷ 8 x 1). The privilege determining unit 80 calculates a privilege price for each vehicle 3 as described above for each content, and determines a privilege point corresponding to the privilege price as privilege information for each vehicle 3. Note that such privilege information determination method is an example, and the present invention is not limited to such a method, and privilege information returned to each vehicle 3 based on the distribution price and the number of distributions of each content. May be determined respectively.

  The privilege determining unit 80 stores the privilege information determined in this way in the privilege table 75. FIG. 9 is a diagram illustrating an example of the privilege table 75. In the privilege table 75, privilege points as privilege information are stored for each vehicle ID. Such privilege points should just be made usable by the owner of each vehicle 3 similarly to well-known privilege information such as mileage. For example, a fee corresponding to the privilege point may be returned to the owner, or a coupon coupon for gasoline discount corresponding to the privilege point may be provided.

[Operation example]
Hereinafter, an operation example of the content distribution system in the present embodiment will be described with reference to FIGS. FIG. 10 is a flowchart showing an operation example of the content distribution system in the present embodiment. FIG. 11 is a diagram illustrating an operation example of the content distribution system in the present embodiment. In the following description, the vehicle 3 is the vehicle 3 having a vehicle ID of 12943, and the vehicle 3 is traveling at the Ogikubo intersection at a speed of 55 km / h in the thick line shown in FIG. 11, and the temperature and humidity near the intersection are 28 degrees. And an example of 45%.

  In the vehicle 3, the control unit 11 of the in-vehicle device 10 receives temperature data, humidity data, and the like from each processing unit such as the temperature measurement unit 12, the humidity measurement unit 13, the GPS information reception unit 14, the vehicle speed detection unit 15, and the navigation IF unit 16. Vehicle position data (latitude and longitude), vehicle speed data, and destination data are acquired as vehicle environment information (S91). Here, the vehicle position data included in the vehicle environment information indicates the latitude and longitude of the Ogikubo intersection, the vehicle speed data indicates 55 km / h, the temperature data indicates 28 degrees, and the humidity data indicates 45%.

  The control unit 11 wirelessly transmits the content request packet including the vehicle environment information thus acquired and the vehicle ID for identifying the vehicle 3 via the wireless communication unit 17 (S92). The wirelessly transmitted content request packet is sent to the distribution server 7 via the network 2.

  In the distribution server 7, when the content request packet is received by the vehicle information receiving unit 77 via the communication unit 41, each processing unit executes the following processing. First, the vehicle information receiving unit 77 acquires a vehicle ID and vehicle environment information from this packet. The acquired vehicle ID and vehicle environment information are sent to the distribution data extraction unit 78.

  The distribution data extraction unit 78 extracts the vehicle registration information of the vehicle ID from the vehicle registration information table 71. In this case, a record (vehicle manufacturer: manufacturer No. 1, vehicle type: one box, vehicle color: blue, year: 2007, medium area: 120 × 100) identified by vehicle ID 12943 in the example of FIG. 5 is extracted. Is done. The distribution data extraction unit 78 extracts a record (distribution data information) satisfying at least one distribution condition from the distribution data information table 72 based on the vehicle registration information and the received vehicle environment information (S93). In this case, in the example of FIG. 6, a record (hereinafter referred to as the first record) specified by the information ID 29549 and a record specified by the information ID 29552 (hereinafter referred to as the second record) are extracted. Is done.

  The distribution data extraction unit 78 acquires the record extracted from the distribution data information table 72, and checks whether each vehicle registration information and vehicle environment information satisfy each distribution condition for each record (S94). The first record satisfies the condition (100 × 100 or more) stored in the medium area field of the distribution data information table 72 when the medium area (120 × 100) of the vehicle registration information satisfies the condition (Ogikubo + The vehicle position data (longitude and latitude indicating the Ogikubo intersection) is satisfied in the vehicle environment information, and the conditions stored in the speed field (from 30 km / h to 60 km / h) meet the vehicle speed data (55 km / h) of the vehicle environment information. Satisfies the condition stored in the temperature field (26 degrees or more) and the temperature data (28 degrees) in the vehicle environment information satisfies the condition (40% or more) stored in the humidity field, the humidity data (45 in the vehicle environment information) %) Is satisfied. In the second record, the medium area (120 × 100) of the vehicle registration information satisfies the condition (100 × 100 or more) stored in the medium area field of the distribution data information table 72.

The distribution data extraction unit 78 calculates the priority for each record extracted as described above by using the weight value extracted from the condition weight table 73 (S95). Specifically, the distribution data extraction unit 78 selects each piece of information that satisfies each distribution condition included in the distribution data information of the distribution data information table 72 extracted as described above, from among the vehicle registration information and the vehicle environment information. Sum each weight value. The priority of the first record is 10180 (= 10000
(Medium area weight value) +30 (place weight value) +30 (speed weight value) +10 (temperature weight value) +10 (humidity weight value) +100 (price weight value)). The priority of the second record is determined to be 1010000 (= 10000 (medium area weight value) +1000000 (weight value when content type is disaster information)). In this example, the record with the highest price among the two extracted records is the advertisement content of the first record. Thereby, the weight value of this price is added to the priority of the first record.

  When the distribution data extraction unit 78 determines the priority of each piece of distribution data information, the distribution data extraction unit 78 selects distribution data information within a predetermined number of records from the one having a high priority. If 1 is set as the predetermined number of records, the second record with the highest priority is selected. The distribution data extraction unit 78 acquires target content data from the content data address included in the selected record. In this case, content data specified by the second record, that is, an image file indicating disaster information is acquired. If the number of requested records is included in the content request packet, or if a value of 2 or more is set as the predetermined number of records stored in advance in the memory or the like, content data corresponding to the number of records is stored. To be acquired.

  The distribution unit 79 transmits the content data acquired by the distribution data extraction unit 78 to the vehicle 3 (S96). Thus, the content data is sent via the communication unit 41 and then sent to the vehicle 3 via the network 2. When the distribution unit 79 finishes distributing the content data, the distribution unit 79 adds 1 to the number of distributions of the content data for the distribution destination vehicle 3 in the distribution number table 74. Here, in the distribution count table 74, 1 is added to the distribution count of the location where the information ID is 29552 (second record) and the vehicle ID is 12943.

  In the vehicle 3, the control unit 11 receives the content data via the wireless communication unit 17 and instructs the display processing unit 18 to display the received content data on the display device 5. Thereby, the content indicated by the content data is displayed on the display surface of the display device 5 of the vehicle 3 (S99). In this example, disaster information is displayed. In the above example, when a plurality of content data (content data of disaster information indicated by the second record and content data of advertisement information indicated by the first record) are transmitted from the distribution server 7, the priority is given. Each content data is displayed according to the degree. When the advertisement content data shown in the first record is displayed, “National client advertisement” is displayed as shown in the example of FIG.

[Operation and Effect of Example]
As described above, in the content distribution system according to the present embodiment, each vehicle environment information such as temperature, humidity, vehicle position, vehicle speed, destination, etc., which is dynamic data collected by each vehicle 3, is distributed by the distribution server. 7 is sent. The distribution server 7 holds each vehicle registration information such as the area (medium area) of the display surface of the display device 5, the vehicle type, and the vehicle color, which is static data about each vehicle 3. In the distribution server 7, appropriate content data is extracted from a plurality of contents based on such dynamic data and static data of each vehicle 3, and each content data is distributed to each vehicle 3. As a result, in each vehicle 3, the distributed content is displayed on the display device 5 having a display surface directed in the vehicle outward direction mounted on each vehicle 3.

  Therefore, according to the present embodiment, each content data distributed from the distribution server 7 is displayed on the display device 5 of each vehicle 3, so that each vehicle 3 can be used as an advertising medium. Since the vehicle 3 itself exists everywhere, an advertising effect can be widely obtained for an advertiser who provides advertisement content data.

Further, according to the distribution server 7 in the present embodiment, since a plurality of distribution conditions can be set as distribution data information for each content, the vehicle 3 that matches the distribution conditions based on the vehicle environment information and the vehicle registration information. On the other hand, desired content can be displayed. Specifically, the content provider can display his / her content on the desired vehicle 3 by setting a desired location, a desired time, a desired vehicle type, a desired vehicle color, and the like as distribution conditions. .

  For example, an advertiser with a strong luxury image may want to display his advertisement on a luxury vehicle. Also, advertisers who target young people to consumers may be more effective if their advertisements are displayed on vehicles located in places where many young people gather. For advertisers of indoor amusement facilities such as bowling alleys and karaoke shops, it may be more effective to display their advertisements on vehicles located in rainy (high humidity) areas. It may be more effective to display a logo advertisement for a vehicle with a high speed, and display a detailed advertisement for a vehicle with a low speed. According to the present embodiment, such a request can be met by appropriately setting the distribution conditions of the distribution data information.

  According to the present embodiment, since appropriate contents are adaptively displayed, it is possible to obtain a higher effect than when the vehicle 3 itself is used as a wrapping medium.

  Further, in the content distribution system in the present embodiment, the priority is calculated for each content extracted as a distribution target, and the content with the higher priority is distributed and displayed with priority. Furthermore, in this embodiment, not only advertisements but also news, disaster information, and weather information are distributed as distribution target contents, and the priority of disaster information with high urgency is set to be high.

  Information that is likely to attract the viewer's interest, such as news, weather information, disaster information, etc. By including the medium value of the display device 5 itself of the vehicle 3 can be raised.

  Furthermore, in this embodiment, a price can be set in the distribution condition as the distribution data information for each content, and a weight value is provided so that the priority for the high-priced content is higher than the low-price content. It has been. As a result, it is easier to distribute content whose price is set higher. As a result, when the distribution conditions are common to a plurality of contents, the content provider sets a high price. For example, since there are many advertisers who want to provide advertising content to vehicles that are located in busy places and vehicles that run in busy hours, auctions occur between these advertisers.

  This not only makes the system meaningful for the content provider, but also for the operator of the content distribution system in the present embodiment, if the distribution price is collected, profits can be obtained. Become.

  Further, in this embodiment, a privilege is given to each vehicle based on the number of times each content is distributed. Therefore, according to the present embodiment, the owner of each vehicle can register with the content distribution system of the present embodiment and obtain a privilege if the vehicle is running. Thereby, the content delivery system in a present Example becomes a system meaningful not only to a content provider and a system operator as mentioned above but to the owner (driver) of a vehicle.
