Corresponding to each advertisement content, one or a plurality of user reactions that are regarded as conversions are determined. Specifically, for example, purchases made through advertising content, acquisition of coupon data, route display or route guidance to related facilities of advertising content, user visits to related facilities, questionnaires Responses to can be converted into conversions. Note that the terminal 20 may detect that the user has visited a related facility based on the current location.

[3. processing]
(1) Provision Processing A provision processing for providing information to the user from the provision system 1 will be described (FIG. 3). This process is repeatedly executed by the providing system 1 when the user is on the boarding vehicle or during driving of the boarding vehicle.

In S <b> 200, the current location of the boarding vehicle is transmitted from the terminal 20 to the server 10.
In S205, the server 10 distributes content suitable for the user to the terminal 20. The content is determined based on the current location of the boarding vehicle, the planned travel route, the passenger, the current date and time, the tag, and the like. The server 10 may distribute content stored in advance in the storage unit 12, or may distribute content newly acquired from the outside via a communication network. Further, what kind of content is specifically distributed will be described later.

  In S <b> 210, the terminal 20 stores the content distributed from the server 10 in the storage unit 22. Further, the terminal 20 deletes unnecessary content (in other words, not suitable for the user) from the content stored in the storage unit 22. Specifically, the terminal 20 may delete the advertising content that has not changed the user's behavior (in other words, the ignored advertising content). Specifically, for example, advertisement content that satisfies all the following conditions (a) to (c) may be regarded as ignored advertisement content.

(A) Conversion is not performed.
(B) The boarding vehicle has not arrived at the facility related to the advertisement content (hereinafter referred to as “related facility”). Note that the related facility may be, for example, a facility such as a store that is an advertisement target by advertisement content, or a facility such as a store that provides an advertisement target.

(C) The facility related to the advertisement content is not set as the destination of the route guidance by the terminal 20 or the in-vehicle device of the boarding vehicle.
In addition, the terminal 20 may delete the advertisement content for a facility whose distance from the current location exceeds a predetermined threshold. Further, the terminal 20 may delete content whose elapsed time from the stored time exceeds a predetermined threshold. Further, the terminal 20 may exclude unnecessary content from being provided to the user without deleting it from the storage unit 22.

  In S <b> 215, the server 10 determines whether the operation trend is stable based on the operation amount received from the terminal 20. If the determination is affirmative (S215: Yes), the server 10 proceeds to S220. If the determination is negative (S215: No), the server 10 proceeds to S240.

  In S220, the server 10 determines whether the speed of the boarding vehicle is equal to or less than a predetermined threshold based on the vehicle state of the boarding vehicle received from the terminal 20. If the determination is affirmative (S220: Yes), the server 10 proceeds to S230. If the determination is negative (S220: No), the server 10 proceeds to S225.

  In S <b> 225, the server 10 determines whether or not the riding vehicle is in an easy state by performing predetermined driving assistance based on the vehicle state received from the terminal 20. Specifically, for example, when all driving operations are automatically performed by automatic driving, it may be considered that driving is easy. If the determination is affirmative (S225: Yes), the server 10 proceeds to S230. If the determination is negative (S225: No), the server 10 proceeds to S240.

  In S230, the server 10 determines whether or not the driver's face direction and line-of-sight direction are stable based on the behavior of the driver received from the terminal 20. That is, the server 10 determines whether or not the driver is checking the vicinity of the host vehicle. If the driver's face orientation and line-of-sight orientation are stable (S230: Yes), the server 10 proceeds to S235; otherwise (S230: No), the server 10 proceeds to S220.

  In S240, the server 10 instructs the terminal 20 not to provide the content. Thereby, the provision of the content is stopped during the provision of the content. Then, the server 10 proceeds to S220. On the other hand, after S235, content is provided according to the driver margin.

  That is, when the process proceeds to S235 through the determinations of S215 to S230, the driving margin does not reach a predetermined level, and the driving becomes easy. For this reason, content is provided according to the driver margin. In S215 to S230, the driving margin is determined based on the driver state and the vehicle state. However, the driving margin may be determined based on one of the driver state and the vehicle state. That is, one of S215 and S220 and S225 may be omitted. In addition, the server 10 may determine the driving margin by further considering the peripheral state. That is, the content may not be provided when the boarding vehicle is highly likely to collide with an object, or when the boarding vehicle is highly likely to depart from the lane or road. Further, the server 10 may provide content without determining the driving allowance.

  In S235, the server 10 calculates a driver margin. Then, the server 10 determines whether or not the driver margin has reached a lower limit value that is a predetermined threshold. If the determination is affirmative (S235: Yes), the server 10 proceeds to S245 and the negative determination is made. In the case (S235: No), the process proceeds to S240.

  In S245, the server 10 selects one or more contents to be provided to the user from the contents stored in the storage unit 22 of the terminal 20. Hereinafter, the selected content is described as target content. The target content is selected according to the driver margin and the content provision frequency. In addition, the provision mode of the target content is selected according to the driver margin. Details will be described later. Then, the server 10 instructs the terminal 20 to provide the target content. In response to the instruction, the terminal 20 outputs the target content stored in the storage unit 22 via both or one of the display unit 25 and the audio output unit 26 (S250). At this time, the server 10 updates the frequency of providing the target content by updating the number of times the target content is provided.

  In addition, the case where the message regarding a driving | operation, a warning, etc. are output via the display part or audio | voice output part used for provision of a content is assumed. In such a case, the terminal 20 may interrupt the provision of the content and output the message or the like.

  In S255, the terminal 20 detects a user's reaction to the provided content based on the operation received via the operation unit 27. The user reaction may be, for example, the fact that conversion has been performed on the provided advertisement content, or the content of the conversion. On the other hand, the user's reaction may be that no conversion has been performed on the provided advertisement content. Further, for example, it may be detected as a user reaction that the related facility of the provided advertisement content is set as the destination of the route guidance by the terminal 20 or the in-vehicle device of the boarding vehicle. Further, for example, it may be detected as a user reaction that a boarding vehicle has arrived at a related facility of the provided advertisement content. Then, the terminal 20 transmits the user's reaction to the server 10. Moreover, the server 10 updates learning information based on the user's reaction received from the terminal 20, and complete | finishes this process.

  Note that the terminal 20 that is providing the content may end the provision of the content in accordance with, for example, an operation received from the user. For example, the terminal 20 may end the provision of the advertisement content when the current location of the boarding vehicle reaches the outside of the fence corresponding to the related facility of the advertisement content being provided. The fence will be described later. Further, for example, the terminal 20 may end the provision of the advertisement content when the user does not respond after a predetermined time has elapsed after the start of the provision of the advertisement content. Further, the terminal 20 may end the provision of the advertisement content when the conversion corresponding to the advertisement content is performed during the provision of the advertisement content. Further, the terminal 20 may continuously detect the user's reaction to the advertising content even after the provision of the advertising content is completed.

  Further, in each step of the providing process, the process performed by the server 10 may be performed by the terminal 20, or the process performed by the terminal 20 may be performed by the server 10.

(2) Content Delivered to Terminal 20 Next, what content is delivered in S205 of the providing process will be described in detail. As described above, the content distributed to the terminal 20 is determined based on the current location of the boarding vehicle, the planned travel route, the passenger, the current date and time, the tag, and the like.

  Specifically, when the boarding vehicle enters a predetermined area, the server 10 may distribute content corresponding to the area. More specifically, a fence that forms a boundary between areas corresponding to related facilities may be set on a road or the like. Then, when the boarding vehicle reaches the inside of the fence corresponding to the related facility, the server 10 may distribute the advertising content about the related facility to the terminal 20. The related facility may be located on the roadside of the boarding vehicle. The roadside means the vicinity of a section on the traveling direction side on the road on which the boarding vehicle is traveling, or the vicinity of the planned travel route of the boarding vehicle. Further, the advertisement content may be distributed in response to a request from the related facility server.

In addition, the server 10 may distribute content according to the current day of the week, time zone, month, season, or the like.
Further, the server 10 may distribute content suitable for the user based on the tag. The content suitable for the user may be, for example, content that matches the user's hobbies or preferences, or content that the user is interested in. That is, the server 10 may infer content suitable for the user based on, for example, tag registration information, web page browsing history, web page access time, purchase records, and the like.

  Further, the server 10 may infer content suitable for the user based on the learning information in the tag. That is, the server 10 may infer the advertisement content that has been converted in the past or the advertisement content highly relevant to the advertisement content as the content suitable for the user. The highly relevant advertising content may be, for example, advertising content of a brand that is the same as or related to the converted advertising content. The highly relevant advertising content may be advertising content that is the same as or similar to the converted advertising content or advertising content related to the advertising content. On the other hand, the server 10 may not distribute advertisement content that has been provided in the past in a predetermined frequency but has not been converted, or that is highly relevant to the advertisement content.

  In addition, the server 10 may distribute content according to the presence or absence of a passenger, the number of passengers, or the attributes of the passengers. Specifically, the server 10 may distribute advertisement contents of related facilities according to the number of drivers and passengers. In addition, when the passenger is a family, the server 10 may distribute advertisement contents of related facilities suitable for visiting by the family. When the passenger is a child, the server 10 is accompanied by a child. It is also possible to distribute advertisement contents of related facilities suitable for visiting. Moreover, when a passenger is a friend, the server 10 may distribute the advertisement content of the related facility suitable for visiting with friends.

(3) Selection of Target Content Next, the method for selecting target content in S245 of the providing process will be described in detail. The server 10 selects the target content according to the driver margin from the content stored in the storage unit 22 of the terminal 20. At this time, the provision mode of the target content is selected according to the driver margin. At this time, the server 10 selects content whose provision frequency has not reached a predetermined level as target content. Specifically, for example, the server 10 selects, as target content, content whose number of provisions has not reached a predetermined threshold or content whose number of provisions per unit time has not reached a predetermined threshold. May be.

  Here, a method of selecting target content according to the driver margin will be described in detail. The driver margin exceeding the above-described lower limit value is classified into three regions, a high region, a middle region, and a low region. Of course, the driver margin of the high region is higher than the driver margin of the middle region, and the driver margin of the middle region is higher than the driver margin of the low region. In addition, a content provision mode using audio and video is described as rich, and a content provision mode using audio and no video is described as poor. In addition, the provision mode of content using one of audio and video may be poor.

  The lower limit value of the driver margin, the threshold value for dividing the high region, the medium region, and the low region, and the threshold value for determining whether the content providing frequency has reached the above level are the threshold value changing unit 161. It can be changed by.

  The server 10 selects rich content when the driver margin is high, and selects poor content otherwise. In addition to this, as the driver margin increases, the server 10 selects content having a longer provision time. In particular, the advertisement content provision time is classified into three types: long (for example, 60 seconds or more), standard (for example, about 20 seconds), and short (for example, 5 seconds or less). When the driver margin is high, the server 10 has long or standard advertisement content, and when the driver margin is medium, the server 10 has standard or short advertisement content and the driver margin is low. In the case of a region, short advertising content may be selected.

  Further, the server 10 may further select content having contents corresponding to the driver margin while performing the selection by the method described above. That is, for example, as the driver margin increases, the server 10 may select higher-priced advertising content. Further, for example, the server 10 may select advertisement content with a lower brand recognition level as the driver margin increases.

  Specifically, when the driver margin is high, the server 10 may select, for example, durable consumer goods such as real estate and cars, or advertising content such as financial products. When the driver margin is high, a long provision time is secured, so that the content suitable for the driver can be watched carefully. For this reason, even if high-priced advertising targets and advertising content with low brand recognition are provided, the user is likely to be interested in the content of the advertising content.

  On the other hand, when the driver margin is in the middle region or the low region, the server 10 may select the advertising content for a low-priced advertising target such as food, beverage, or entertainment, or the advertising content with high brand recognition. good. In particular, when the driver margin is low, the server 10 may select, for example, short advertisement content that appeals only the brand image.

  Note that, when providing content in a poor provision mode, the server 10 may select content with a rich provision mode as target content, output audio of the content, and not output video.

  Further, the server 10 may select the same content as the target content a plurality of times within a range where the provision frequency does not reach the above level. That is, even if the content is provided in the past, the server 10 may select again the content that is estimated to be suitable for the user based on the tag as the target content. When advertisement content that is presumed to be suitable for the user based on the tag has been provided in the past, the server 10 selects another advertisement content highly relevant to the advertisement content as target content. Also good. Specifically, for example, the advertising content that is presumed to be suitable for the user and the advertising target are the same, but the advertising content that is different may be used as the target content.

[4. effect]
According to the present embodiment, the following effects can be obtained.
(1) In the providing system 1 of the present embodiment, content is provided according to the driver margin. That is, appropriate content according to the magnitude of the burden is provided to the user at an appropriate timing according to the magnitude of the burden generated on the driver. If the driver margin is high, it is considered that the driver accepts provision of content (in other words, it does not seem annoying). For this reason, it is considered that the higher the driver margin is, the higher the possibility that the driver actively sees and listens to the content. Therefore, according to the present embodiment, it is possible to provide entertainment, useful information, and the like while suppressing annoying the user by providing the content. Thereby, information can be provided to the user more suitably.

  (2) Moreover, in the providing system 1, content is provided according to the margin. That is, appropriate content according to the magnitude of the burden is provided to the user at an appropriate timing according to the magnitude of the burden in driving the vehicle.

Therefore, information can be provided to the user more suitably.

  (3) More specifically, in the providing system 1, a driver margin and a driving margin are provided as margins. When the driving margin does not reach a predetermined level, content is provided according to the driver margin. For this reason, when the driving of the vehicle is easy, appropriate content according to the magnitude of the burden is provided at an appropriate timing according to the magnitude of the burden generated on the driver. For this reason, it is possible to provide entertainment, useful information, and the like while suppressing annoying the user by providing the content. Therefore, information can be provided to the user more suitably.

  (4) Further, in the providing system 1, the content providing mode is determined according to the driver margin. That is, when the burden on the driver is small, the content is provided in a rich provision mode. On the other hand, when the burden on the driver is large, the content is provided in a poor provision mode. In other words, the content is provided in a provision form that is easily received by the driver in accordance with the burden on the driver. For this reason, it is possible to provide entertainment, useful information, and the like while suppressing annoying the user by providing the content. Therefore, information can be provided to the user more suitably.

  (5) Further, in the providing system 1, the provided content is determined according to the driver margin. For this reason, according to the burden which has arisen in the driver, the content of the content which is easy to be accepted by the driver is provided. As a result, it is possible to provide entertainment, useful information, and the like while suppressing annoying the user by providing the content. Therefore, information can be provided to the user more suitably.

  (6) Furthermore, in the providing system 1, the advertisement content to be provided is determined according to the driver margin. For this reason, it is possible to provide advertisement content that is easily accepted by the driver according to the burden on the driver. This makes it possible to provide entertainment, useful information, and the like while suppressing annoying the user by providing advertisement content. Therefore, information can be provided to the user more suitably.

  (7) Also, in the providing system 1, content is not provided when the driver margin does not reach a predetermined level. For this reason, content is not provided when the burden on the driver is large. Therefore, it can suppress giving trouble to a user.

(8) Also, in the providing system 1, content corresponding to the current location of the boarding vehicle is provided. For this reason, more useful information is provided.

  (10) Also, in the providing system 1, content suitable for the user is distributed from the server 10 to the terminal 20, and the content is provided. Specifically, content corresponding to the current location of the boarding vehicle, the current date and time, the user's hobbies, preferences, interests, or the like is distributed to the terminal 20. Therefore, information can be provided to the user more suitably.

  (11) Further, in the providing system 1, unnecessary contents are deleted from the contents distributed from the server 10 to the terminal 20 and stored in the storage unit 22 of the terminal 20. For this reason, it can suppress that unnecessary content is repeatedly provided. Therefore, information can be provided to the user more suitably. Further, the capacity of the storage unit 22 can be saved.

  (12) Further, in the providing system 1, content suitable for the user is estimated based on the user's reaction to the provided content. Then, the content estimated to be suitable for the user is distributed and provided to the terminal 20. For this reason, content that matches the user's hobbies, preferences, interests, or the like is provided. Therefore, information can be provided to the user more suitably.

  (13) In addition, when the conversion corresponding to the advertisement content being provided is performed, the providing system 1 ends the provision of the advertisement content. For this reason, it can suppress that an advertising content is provided continuously after conversion. Therefore, information can be provided to the user more suitably.
