The information providing device 10 according to the present embodiment provides the occupant with the search result for the search request from the occupant of the vehicle 30. The vehicle 30 is, for example, any type of vehicle such as a gasoline vehicle, a diesel vehicle, an HV (hybrid vehicle), a PHV (plug-in hybrid vehicle), an EV (electric vehicle), or an FCV (fuel cell vehicle). The vehicle 30 may be driven by the driver or the driving may be automated at any level. The level of automation is, for example, one of Level 1 to Level 5 in the SAE (Society of Automotive Engineers) leveling. The vehicle 30 may be a MaaS (Mobility as a Service) dedicated vehicle. The vehicle 30 includes an in-vehicle device 31. The vehicle-mounted device 31 accepts a search request from the occupant of the vehicle 30, presents the search information provided by the information providing device 10 to the occupant in response to the search request, and the like.

As shown in FIG. 1, the information providing device 10 receives a user's action history such as a search history, a reservation history, a payment history, and a location information transmitted from the user terminal 20, for example. The search history is information about keywords and the like searched by the user via the user terminal 20. The reservation history is information about facilities and the like reserved by the user via the user terminal 20. The payment history is information about products or services settled by the user via the user terminal 20. The position information is the position information of the user terminal 20. Based on the location information, it is possible to identify which facility the user has stayed for and how long.

Further, the information providing device 10 receives, for example, the surrounding situation information, the occupant information, the destination setting information, and the search request transmitted from the vehicle-mounted device 31 of the vehicle 30. The surrounding situation information is information on the degree of congestion around the vehicle 30. The surrounding situation information is, for example, an image captured by an imaging device mounted on the vehicle 30 and capturing the surroundings of the vehicle 30. The occupant information is information about the occupants of the vehicle 30. The occupant information is, for example, an image captured by an imaging device mounted on the vehicle 30 and capturing the inside of the vehicle 30. The occupant information may be input by the occupant of the vehicle 30. The destination setting information is, for example, information such as a destination set in the navigation device mounted on the vehicle 30. The search request is a request for the occupants of the vehicle 30 to provide information on facilities and the like.

In addition, the information providing device 10 receives facility information and word-of-mouth information from the external information source 40. Facility information is information about the facility. Word-of-mouth information is information related to the evaluation of the facility by users who have used the facility. The external information source 40 is, for example, a web server that publishes facility information and word-of-mouth information, a database that stores facility information and word-of-mouth information, or a search server that can search facility information and word-of-mouth information on the Internet.

As shown in FIG. 1, the information providing device 10 includes a preference learning unit 11, an image recognition unit 12, an occupant estimation unit 13, a visiting facility evaluation unit 14, an individual preference database 15, and an external information database 16. A search condition setting unit 17 and a candidate facility selection unit 18 are provided. The search condition setting unit 17 and the candidate facility selection unit 18 constitute the search unit 19.

When the information providing device 10 is realized by a computer, each of the above-described parts included in the information providing device 10 is realized by the CPU reading and executing the program stored in the memory.

The preference learning unit 11 learns the user's preference of the user terminal 20 based on the search history, reservation history, payment history, location information, and the like transmitted from the user terminal 20. The preference learning unit 11 stores a preference table showing the learned preferences for each user in the personal preference database 15.

The image recognition unit 12 performs image recognition for various images. For example, the image recognition unit 12 performs image recognition on an image captured by capturing the surroundings of the vehicle 30 as peripheral situation information, an image captured by capturing the inside of the vehicle 30 as occupant information, and the like.

The occupant estimation unit 13 estimates which user is the occupant in the vehicle 30 based on the occupant information. For example, when the occupant information is an image captured by capturing the inside of the vehicle 30, the occupant estimation unit 13 identifies the occupant's face included in the image based on the result of image recognition by the image recognition unit 12 for the image. The personal preference database 15 stores the user's facial photograph, and the occupant estimation unit 13 searches for the facial photograph stored in the personal preference database 15 using the occupant's facial image in the captured image as a search key. Therefore, it is possible to estimate which user the occupant is.

The visiting facility evaluation unit 14 acquires the evaluation result of the facility by the user and stores it in, for example, the external information database 16. Further, the visiting facility evaluation unit 14 may output the evaluation result of the facility by the user to the preference learning unit 11. By doing so, the preference learning unit 11 can learn the user's preference based on the evaluation result of the facility by the user.

The personal preference database 15 stores an action history table showing an action history transmitted from the user terminal 20 of the user for each user. In addition, the personal preference database 15 stores, for each user, a preference table showing the preference of the user, which has been learned by the preference learning unit 11.

The final arrival point is the point where the vehicle 30 finally arrives after visiting the facility.

FIG. 3 is a diagram showing a configuration example of a preference table stored in the personal preference database 15. The preference table includes information indicating the tendency of the facility visited by the user as the user's preference for each user. In FIG. 3, items showing the tendency of restaurants visited by the user as the user's preference are mainly shown.

As shown in FIG. 3, the personal preference database 15 stores the out-of-living area flag, the condition, and the visited facility / number of times in the preference table in association with each other.

The out-of-living area flag is a flag indicating whether the restaurant visited by the user is a facility within the living area of the user or a facility outside the living area of the user. The condition indicates a condition when the user visits a restaurant. The conditions include, for example, the number of people visiting alone or with two or more people, and the time of visiting in the daytime or at night. The number of visits / number of visits indicates the category of the facility visited by the user, the number of visits to the facility for each category, the characteristics of the facility, etc., in the scene indicated by the out-of-living area flag and the condition. Categories such as Chinese food are more detailed than genres such as restaurants.

With reference to FIG. 1 again, the external information database 16 stores various information used for creating a response to the search request, such as facility information and word-of-mouth information provided by the external information source 40. The facility information includes information indicating the location of the facility for each facility. The word-of-mouth information includes information indicating the evaluation of the facility for each facility.

When the search request from the occupant of the vehicle 30 is transmitted via the vehicle-mounted device 31, the search condition setting unit 17 sets the search condition according to the occupant. Specifically, the search condition setting unit 17 sets search conditions including the tendency of the facility visited by the user, the location of the facility, and the evaluation of the facility. For example, the search condition setting unit 17 includes the genre of the facility preferred by the occupant learned from the behavior history of the occupant of the vehicle 30 in the search condition as a condition of the tendency of the facility visited by the occupant. The search condition setting unit 17 includes the evaluation requested by the occupant, which is estimated from the behavior history of the occupant of the vehicle 30, in the search condition as the evaluation condition of the facility visited by the occupant. The search condition setting unit 17 includes the area to which the occupant moves, which is identified from the position information of the vehicle 30 and the destination, as a condition of the location of the facility visited by the occupant in the search condition.

The search condition setting unit 17 may include, for example, an area from the current position of the vehicle 30 to the final destination, a genre of facilities preferred by the occupants, scenes such as the number and relationships of occupants in the vehicle 30, current time, budget, and so on. Also, set search conditions according to word-of-mouth evaluation. That is, for example, the search condition setting unit 17 is a facility that exists in which area, belongs to what genre, is suitable for what kind of scene, can be visited at what time, can be used at what price, and has a high reputation. Is specified as a search condition whether to select. The area from the current position of the vehicle 30 to the final destination is specified from the position information of the vehicle 30 and the destination. The location information of the destination is specified from the destination setting information, but if the information is insufficient, the occupant may be asked directly. The genre, budget, and word-of-mouth rating of the facility preferred by the occupants are identified from the preference table, but may be asked directly by the occupants if information is lacking. Scenes such as the number and relationships of occupants in the vehicle 30 are specified from the occupant information, but if the information is insufficient, the occupants may be asked directly.

The candidate facility selection unit 18 searches the external information database 16 based on the search conditions set by the search condition setting unit 17. The candidate facility selection unit 18 selects a candidate facility to be visited by the occupant by searching, and provides the occupant with information indicating the selected candidate facility as search information. When there are a plurality of candidate facilities that satisfy the search conditions, the candidate facility selection unit 18 obtains search information for the plurality of candidate facilities according to the tendency of the facilities visited by the user, the location of the facilities, and the evaluation of the facilities. Determine the priorities to provide. For example, the candidate facility selection unit 18 creates a list in which search information of the candidate facilities is arranged in descending order of preference of the occupants for the genre to which the candidate facility belongs, and transmits the list to the vehicle 30. The candidate facility selection unit 18 creates a list in which the search information of the candidate facilities is arranged in descending order of evaluation, and transmits the list to the vehicle 30. The candidate facility selection unit 18 creates a list in which the search information of the candidate facilities is arranged in the order in which the location is closest to the position of the vehicle 30, and transmits the list to the vehicle 30.

The candidate facility selection unit 18, for example, the distance between the facility shown in the search information and the current position of the vehicle 30, the genre with high occupant preference, the degree of congestion of the facility, the presence or absence of a parking lot, the word-of-mouth evaluation, and the possibility of smoking. Determine the priority of search information based on the above. The distance between the facility shown in the search information and the current position of the vehicle 30 is calculated from the facility information and the position information of the vehicle 30. The genres with high occupant preference are estimated from the behavior history table. The degree of congestion of the facility and the presence or absence of a parking lot are estimated from the information obtained from the facility, the result of image recognition by the image recognition unit 12 for the image captured by the image pickup device installed in the facility, and the like. In addition, smoking is determined from the information obtained from the facility.

The search unit 19 does not provide search information for facilities whose business hours end between the estimated arrival time at the facility and the expected staying time at the facility. May be set and the priority may be determined. Further, when searching for a facility other than a restaurant, the search unit 19 may set search conditions and determine a priority in consideration of the weather and the like.

FIG. 4 is a flowchart showing an example of the operation of the information providing device 10 according to the present embodiment. In FIG. 4, it is assumed that the final destination of the vehicle 30 has already been set.

When the user gets on the vehicle 30, the on-board unit 31 detects the user's boarding and transmits the occupant information about the occupant including the boarded user to the information providing device 10. The occupant information is, for example, an image obtained by capturing the inside of the vehicle 30 with an imaging device.

The occupant estimation unit 13 estimates which user the occupant of the vehicle 30 is based on the occupant information transmitted from the vehicle-mounted device 31 (step S11). When a plurality of occupants are on board, the occupant estimation unit 13 also estimates the relationship between the plurality of occupants. The occupant estimation unit 13 stores the estimation result based on the occupant information in the personal preference database 15 (step S12).

When the occupant of the vehicle 30 requests a facility search, the vehicle-mounted device 31 transmits the search request to the information providing device 10. In the following, it is assumed that the search for facilities by the occupants requires an ambiguous search such as "delicious shop" or "want to go sightseeing" instead of a pinpoint search for specifying a specific facility.

The information providing device 10 receives the search request transmitted from the vehicle-mounted device 31 (step S13). The search condition setting unit 17 sets search conditions according to the occupant who requested the search (step S14). The method of setting the search condition is as described above.

The candidate facility selection unit 18 searches the external information database 16 for the target facility that matches the search condition based on the search condition set by the search condition setting unit 17 (step S15). When a plurality of facilities match the search conditions, the candidate facility selection unit 18 creates a facility list that displays the search information of the plurality of facilities in a predetermined priority order. The method of determining the priority order has already been described. The information providing device 10 transmits the created facility list to the vehicle 30 (step S16).

The vehicle-mounted device 31 receives the facility list transmitted from the information providing device 10 and displays it on a display device or the like mounted on the vehicle 30. Depending on the display of the facility list, the facility shown in the search information can be selected by the occupant.

When the on-board unit 31 determines that a facility included in the facility list is set as a stopover and has visited the facility, the on-board unit 31 requests the occupant of the vehicle 30 to input the evaluation result for the facility. Whether or not the facility has been visited can be determined based on, for example, the location information of the facility and the location information of the vehicle 30.

When the evaluation result of the facility is input, the vehicle-mounted device 31 transmits the input evaluation result to the information providing device 10.

The information providing device 10 receives the evaluation result of the facility transmitted from the vehicle-mounted device 31 (step S17). The visiting facility evaluation unit 14 stores the received evaluation result of the facility in the external information database 16 (step S18). Further, the visiting facility evaluation unit 14 may calculate a difference between the evaluation result of the facility by the occupants of the vehicle 30 and the word-of-mouth evaluation of the facility, and output the difference to the preference learning unit 11. By doing so, the preference learning unit 11 can learn the preference of the occupant in consideration of the difference between the evaluation result of the facility by the occupant of the vehicle 30 and the word-of-mouth evaluation of the facility.

As described above, in the present embodiment, the information providing device 10 includes a personal preference database 15 that stores information indicating the tendency of the facility visited by the user as the user's preference, information indicating the location of the facility for each facility, and information indicating the location of the facility. By referring to the information stored in the external information database 16 that stores the information indicating the evaluation of the facility, the personal preference database 15, and the external information database 16, a search including the respective conditions of the tendency, the location, and the evaluation. It is provided with a search unit 19 that sets conditions, selects candidate facilities to be visited by vehicle occupants by searching based on the set search conditions, and provides information indicating the selected candidate facilities to occupants as search information. When there are a plurality of candidate facilities satisfying the search condition, the search unit 19 determines the priority of providing the search information of the plurality of candidate facilities according to the tendency, the location, and the evaluation.

According to the present embodiment, it is possible to perform a search in consideration of the occupant's preference, facility evaluation, vehicle and destination location, and the like. It is not mandatory for the occupant to enter this information, so it is not troublesome. In addition, the search results can be presented to the occupants in consideration of the occupant's preferences, facility evaluation, vehicle and destination locations, and the like. Therefore, it is possible to provide highly accurate information more easily.

In the present embodiment, the information providing device 10 provides the user with information extracted from the information collected on the center side in response to an inquiry from the user who is a occupant of the vehicle 30. Inquiries may be made by voice. The search conditions for searching at the center are set according to at least the number of times the user has visited a facility such as a store in the past, the evaluation of the facility, and the distance or positional relationship between the current location and the destination. To. The priority for providing information is determined at least according to the number of times the user has visited a facility such as a store in the past, the evaluation of the facility, and the distance or positional relationship between the current location and the destination. ..
