The purchase history information may further include genre information indicating the genre of the purchased item, such as food, beverages, daily necessities, and clothing.

It is preferable to obtain purchase history information limited to products that are purchased periodically, such as consumables. In this case, for example, the information may be obtained by limiting it to genre information, or by limiting it to products with purchase prices below a threshold price.

Search history information is information that indicates the search history of products, stores, etc. on a website. For each passenger, the search history information includes result information that indicates the search results and information on the date and time when the search was performed. The search history information includes, for example, information on the products or stores obtained as search results and information on the date and time when the search was performed. The search history information may further include genre information that indicates the genre of the searched product or store.

The history information acquisition unit 31 may acquire the information from, for example, an electronic device used by the passenger. For example, the information may be acquired from purchase history information, electronic payment information, search history information, and the like stored in the electronic device. In this case, it is assumed that the electronic device and the vehicle are connected so as to be able to send and receive data.

The history information acquisition unit 31 may acquire consumption history information that can be acquired in association with an account from an external server device, for example, from an account used by a passenger when using a service provided via the Internet. In this case, it is assumed that the account information of the passenger of the vehicle is stored in a storage unit, not shown, for example. The history information acquisition unit 31 may acquire consumption history information that can be acquired in association with an electronic device from an electronic device used by the passenger. It may acquire consumption history information that can be acquired in association with an account used when using the electronic device from an electronic device used by the passenger.

In this embodiment, the history information acquisition unit 31 acquires consumption history information of the driver, who is the passenger.

The analysis unit 32 analyzes the product purchasing tendency for each passenger based on the consumption history information acquired by the history information acquisition unit 31. For example, the analysis unit 32 may analyze the average purchase interval for each product based on the consumption history information. For example, the analysis unit 32 analyzes the average product purchase interval to be the purchase of one box of drinking water every 20 days.

The estimation unit 33 estimates the passenger's behavior regarding the purchase of a product based on the consumption history information acquired by the history information acquisition unit 31. More specifically, the estimation unit 33 estimates the passenger's behavior regarding the purchase of a specific product based on the analysis result of the analysis unit 32 and the current date and time. For example, if a period close to the average purchase interval of a specific product has passed since the last purchase, or a period longer than the average has passed, the estimation unit 33 estimates that the passenger is likely to take action to purchase the product. For example, if the analysis result indicates that drinking water is purchased every 20 days and 18 days have passed since the last purchase date, the estimation unit 33 estimates that the passenger is likely to take action to purchase drinking water. In this way, the estimation unit 33 estimates a specific product that the passenger is likely to take action to purchase. The estimation unit 33 may estimate the behavior regarding the store where the passenger purchases the product. For example, if the analysis result indicates that there is a tendency to purchase products at a supermarket during lunch time on the first Saturday, and the current day is the first Saturday, the estimation unit 33 estimates that the passenger is likely to take action to purchase the product at the supermarket.

The extraction unit 34 extracts recommended destinations based on the estimation result of the estimation unit 33 and the store information acquired by the store information acquisition unit 24. In this embodiment, the extraction unit 34 extracts recommended destinations based on the estimation result of the estimation unit 33, the map information acquired by the map information acquisition unit 23, and the store information acquired by the store information acquisition unit 24. For example, when the estimation result indicates that the passenger is likely to take action to purchase a specific product, the extraction unit 34 acquires store information of a store that handles the product. The extraction unit 34 may acquire store information of a store that handles a product with the same product number, or a store that handles similar products based on the genre information. The extraction unit 34 extracts one or more recommended destinations. In this way, the extraction unit 34 extracts stores where the specific product that is likely to be purchased by the passenger can be purchased as recommended destinations.

The extraction unit 34 may extract a store close to the current location of the vehicle as a recommended destination. When a destination is set in the navigation system 1, the extraction unit 34 may extract a store close to the destination or a store located along the route as a recommended destination.

The extraction unit 34 may acquire store information including business hours information and congestion information. The extraction unit 34 may extract stores that are open at the current time or the expected arrival time as recommended destinations. The extraction unit 34 may extract stores that are not crowded at the current time or the expected arrival time as recommended destinations. The congestion information may be predicted information on the degree of congestion estimated from the congestion history of the store by day of the week or time of day, or may be real-time information on the real-time congestion information of the store acquired from the store's website, etc.

The suggestion unit 35 suggests stores where the product can be purchased as candidates for recommended destinations based on the extraction results of the extraction unit 34. More specifically, the suggestion unit 35 makes a list of the candidates for recommended destinations and causes the display control unit 28 to display the list. When the destination setting screen of the navigation system 1 is displayed on the display unit 16, the suggestion unit 35 may cause the candidates for recommended destinations to be displayed on the destination setting screen. In this way, the suggestion unit 35 suggests, as recommended destinations, stores where a specific product can be purchased that is likely to cause the passenger to take purchasing action.

The suggestion unit 35 may present business hours and congestion information along with recommended destination candidates.

The suggestion unit 35 may sort and present the recommended destination candidates. For example, the sorting may be in order of proximity to the current location or the destination. For example, the sorting may be in order of least crowdedness.

<Processing in the navigation control device>
Next, information processing in the navigation system 1 will be described with reference to Figures 2 and 3. Figure 2 is a flowchart showing the flow of processing in the navigation control device 20 according to the first embodiment.

The processing of the flowchart shown in Figure 2 is executed at any timing, such as when the vehicle engine is started, when the navigation system 1 is booted, or when the passenger operates to start processing.

The navigation control device 20 acquires history information by the history information acquisition unit 31 (step S101). More specifically, the navigation control device 20 acquires consumption history information of the vehicle's occupants from outside the navigation system 1 via the communication unit 15 by the history information acquisition unit 31. The navigation control device 20 proceeds to step S102.

The navigation control device 20 analyzes the consumption history using the analysis unit 32 (step S102). More specifically, the navigation control device 20 analyzes the product purchasing tendency for each passenger using the analysis unit 32 based on the consumption history information acquired by the history information acquisition unit 31. The navigation control device 20 analyzes, for example, the purchase interval for each product using the analysis unit 32. The navigation control device 20 proceeds to step S103.

The navigation control device 20 uses the estimation unit 33 to estimate the purchasing behavior of each passenger (step S103). More specifically, the navigation control device 20 uses the estimation unit 33 to estimate the passenger's behavior regarding product purchases based on the analysis results of the analysis unit 32 and the current date and time. For example, the navigation control device 20 uses the estimation unit 33 to estimate that the passenger is likely to take action to purchase a product if a period close to the average interval between product purchases has passed since the last purchase, or if a period longer than the average has passed. The navigation control device 20 proceeds to step S104.

The navigation control device 20 uses the extraction unit 34 to extract stores as recommended destinations (step S104). More specifically, the navigation control device 20 uses the extraction unit 34 to extract recommended destinations based on the estimation result of the estimation unit 33, the map information acquired by the map information acquisition unit 23, and the store information acquired by the store information acquisition unit 24. For example, if the estimation result indicates that the passenger is likely to take action to purchase a specific product, the navigation control device 20 uses the extraction unit 34 to acquire store information of a store that sells the product. One or more recommended destinations are extracted. The navigation control device 20 proceeds to step S105.

The navigation control device 20 determines whether or not there is a recommended destination (step S105). More specifically, the navigation control device 20 determines whether or not there is a recommended destination depending on whether or not a recommended destination has been extracted based on the extraction result of the extraction unit 34. If the extraction unit 34 extracts a recommended destination and it is determined that there is a recommended destination (Yes in step S105), the navigation control device 20 proceeds to step S106. If the extraction unit 34 does not extract a recommended destination and it is determined that there is no recommended destination (No in step S105), the navigation control device 20 ends the process.

If it is determined that there is a recommended destination (Yes in step S105), the navigation control device 20 executes a process of proposing a recommended destination by the proposing unit 35 (step S106). The process of proposing a recommended destination is the process of the flowchart shown in FIG. 3, which will be described later. After the process of proposing a recommended destination is completed, the navigation control device 20 ends the process.

Next, the process of proposing recommended destinations will be explained using Figure 3.

The navigation control device 20 determines whether the navigation system 1 is displaying a destination setting screen (step S111). More specifically, the navigation control device 20 determines whether the display control unit 28 is causing the display unit 16 to display the destination setting screen. If the navigation control device 20 determines that the destination setting screen is being displayed (Yes in step S111), it proceeds to step S114. If the navigation control device 20 determines that the destination setting screen is not being displayed (No in step S111), it proceeds to step S112.

If it is determined that the destination setting screen is not being displayed (No in step S111), the navigation control device 20 notifies the passenger via the notification control unit 29 that there are candidates for recommended destinations (step S112). More specifically, the navigation control device 20 causes the notification control unit 29 to output a voice to the notification unit 17 that there are candidates for recommended destinations based on a control signal from the suggestion unit 35. The navigation control device 20 proceeds to step S113.

The navigation control device 20 transitions the display screen of the navigation system 1 to a destination setting screen (step S113). More specifically, the navigation control device 20 causes the display control unit 28 to display the destination setting screen on the display unit 16. The navigation control device 20 proceeds to step S114.

The navigation control device 20 displays the recommended destination candidates on the destination setting screen of the navigation system 1 (step S114). The navigation control device 20 causes the display control unit 28 to display the destination setting screen including the recommended destination candidates on the display unit 16. The navigation control device 20 may, for example, cause the display control unit 28 to add the list of recommended destination candidates to the list of destination candidates and display them. The navigation control device 20 may, for example, cause the display control unit 28 to display the recommended destination candidates in a pop-up. The navigation control device 20 proceeds to step S115.

The navigation control device 20 determines whether a destination setting operation for setting a destination or a recommended destination has been detected (step S115). More specifically, if the operation reception control unit 22 has acquired operation information indicating that a destination setting operation has been performed (Yes in step S115), the process proceeds to step S116. If the operation reception control unit 22 has not acquired operation information indicating that a destination setting operation has been performed (No in step S115), the navigation control device 20 ends the process.

If a destination setting operation is detected (Yes in step S115), the navigation control device 20 searches for a route to the destination or a recommended destination (step S116). More specifically, the route search unit 26 searches for a normal route from the current vehicle position to the destination based on the current vehicle position information and the destination position information. If a destination is selected from among the recommended destination candidates, the route search unit 26 searches for a normal route from the current vehicle position to the recommended destination based on the current vehicle position information and the recommended destination position information. The navigation control device 20 proceeds to step S117.

The navigation control device 20 provides route guidance (step S117). More specifically, the navigation control device 20 provides route guidance using the route guidance unit 27. The navigation control device 20 ends the process.

For example, the analysis unit 32 may analyze the relationship with the day of the week based on the consumption history information. For example, the analysis unit 32 may analyze that there is a tendency to eat fast food at lunchtime on the first Saturday of each month.

The estimation unit 33 estimates the passenger's behavior regarding eating and drinking of food and drink based on the consumption history information acquired by the history information acquisition unit 31. More specifically, the estimation unit 33 estimates the passenger's behavior regarding eating and drinking based on the analysis result of the analysis unit 32 and the current date and time. More specifically, for example, if a period close to the average interval between eating and drinking has passed since the last time a certain food and drink was consumed, or a period longer than the average has passed, the estimation unit 33 estimates that the passenger is likely to take the behavior of eating and drinking the food and drink. For example, if the analysis result indicates that there is a tendency to eat fast food at lunchtime on the first Saturday, and the day is the first Saturday, the estimation unit 33 estimates that the passenger is likely to take the behavior of eating and drinking fast food. In this way, the estimation unit 33 estimates the food and drink and genre that are likely to cause the passenger to take the behavior of eating and drinking. The estimation unit 33 may estimate the behavior regarding the restaurant where the passenger will eat. For example, if the analysis results indicate that there is a tendency to eat and drink at a fast food restaurant during lunchtime on the first Saturday, and the day is the first Saturday, the estimation unit 33 estimates that there is a high possibility that the passenger will take the action of eating and drinking at a fast food restaurant.

The estimation unit 33 may estimate eating and drinking behavior for each food and drink, or may estimate eating and drinking behavior for each genre. The estimation unit 33 may estimate eating and drinking behavior for each food and drink, for example, "hamburger." The estimation unit 33 may estimate eating and drinking behavior for each genre, for example, "fast food."

The estimation unit 33 may estimate the eating and drinking behavior of the passenger assuming that the passenger eats and drinks in a balanced manner. For example, when it is determined from the consumption history information that there is a bias in the foods and drinks or genres, the estimation unit 33 may estimate that the passenger wishes to eat a balanced diet.

If the passenger has irregular meal times, the estimation unit 33 may estimate eating and drinking behavior so that the passenger can eat regularly. For example, if the passenger has irregular meal times, the estimation unit 33 may estimate that the passenger wishes to have regular meal times.

The extraction unit 34 extracts stores where food and drink can be consumed as recommended destinations based on the estimation result of the estimation unit 33 and the store information acquired by the store information acquisition unit 24. In this embodiment, the extraction unit 34 extracts recommended destinations based on the estimation result of the estimation unit 33, the map information acquired by the map information acquisition unit 23, and the store information acquired by the store information acquisition unit 24. For example, when the estimation result indicates that the passenger is likely to take the action of eating and drinking a specific food and drink, the extraction unit 34 acquires store information of restaurants where the food and drink can be consumed. For example, when the estimation result indicates that the passenger is likely to take the action of eating and drinking at a restaurant of a specific genre, the extraction unit 34 acquires store information of restaurants of the genre. For example, in the case of "hamburgers," the extraction unit 34 may extract stores limited to fast food restaurants of the same chain, or may extract stores without distinguishing between fast food restaurants of different chains.

The suggestion unit 35 suggests stores that serve food and drink as candidates for recommended destinations based on the extraction results of the extraction unit 34.

Next, information processing in the navigation system 1 will be described with reference to FIG. 4. The processing of the flowchart shown in FIG. 4 is executed at any timing, such as when the vehicle engine is started, when the navigation system 1 is started, when the current time is within a meal time, or when the passenger starts the processing. The processing of steps S121, S124 to S126 shown in FIG. 4 is the same as that of steps S101, S104 to S106 shown in FIG. 2.

The navigation control device 20 uses the analysis unit 32 to analyze the eating and drinking habits of each passenger based on the consumption history information acquired by the history information acquisition unit 31 (step S122). The navigation control device 20 proceeds to step S123.

The navigation control device 20 estimates the eating and drinking behavior of each passenger by the estimation unit 33 (step S123). More specifically, the navigation control device 20 estimates the eating and drinking behavior of each passenger by the estimation unit 33 based on the analysis result of the analysis unit 32 and the current date and time. The navigation control device 20 proceeds to step S124.

As described above, in this embodiment, the eating and drinking behavior of the passenger is estimated based on consumption history information acquired from outside the navigation system 1 via the communication unit 15. In this embodiment, stores that serve food and drink are extracted as recommended destinations based on the estimation results and store information. In this embodiment, stores that serve food and drink are suggested as recommended destinations based on the extraction results of the extraction unit 34. According to this embodiment, recommended destinations such as stores can be more appropriately suggested according to the passengers of the vehicle based on the consumption history information.

This embodiment can analyze the eating and drinking habits of passengers and suggest restaurants where passengers can eat and drink at the appropriate time if they are in the mood to eat or drink. This embodiment can help prevent passengers from eating unbalanced meals.

[Third embodiment]
In this embodiment, a case will be described in which the store information stored in the store information storage unit 14 includes advertisement information.

The store information includes, for example, advertising information such as electronic advertisements for each store. The store information includes sales price information for products advertised in the store's electronic advertisements. More specifically, the advertising information includes product number information and sales price information for the advertised products. The advertising information may further include advertisement validity period information.

The extraction unit 34 extracts stores by comparing the sales price information in the store information with the purchase price information in the purchase history information. More specifically, if the estimation result indicates that the passenger is highly likely to take action to purchase a specific product, the extraction unit 34 acquires store information of a store that sells the product and has a low price. The extraction unit 34 may compare the consumption history information with the store information and extract, as a recommended destination, a store whose price in the store information is lower than the price in the product's purchase history.

The suggestion unit 35 may present price information along with the recommended destination candidates. The suggestion unit 35 may present the recommended destination candidates sorted in ascending price order. For example, the suggestion unit 35 may present to the passenger that the ticket can be purchased at a lower price than if it were purchased on a website.

As described above, this embodiment makes it possible to more appropriately suggest recommended destinations such as stores based on price.

[Fourth embodiment]
In this embodiment, a case will be described in which discount information is included in the store information stored in the store information storage unit 14 .

The store information includes, for example, discount information such as electronic discount coupons for each store. The discount information includes product number information and discount information for the listed products. The discount information may further include information on the validity period of the discount.

The extraction unit 34 extracts stores based on the presence or absence of discount information on the store's electronic discount coupon. For example, if the estimation result indicates that the passenger is likely to take action to purchase a specific product, the extraction unit 34 acquires store information of stores that handle the product and have discount information.

The suggestion unit 35 may present discount information along with the recommended destination candidates. The suggestion unit 35 may present the recommended destination candidates sorted according to whether or not they have discount information.

As described above, according to this embodiment, recommended destinations such as stores can be more appropriately suggested depending on whether or not discount information is available.
