The product purchase guidance system 1 according to the present embodiment includes a server 20 and an in-vehicle device 30.

  In the present embodiment, the server 20 stores purchase history information of products purchased by the user, and provides the purchase history information to the in-vehicle device 30 used by the user. In one example, when the point card 10 is used at the time of purchasing a product, the server 20 acquires product purchase information from a store where the point card 10 is used. In the service using the point card, when the user presents the point card 10 to the store when purchasing the product, points are given to the point card 10 according to the purchase price of the product. The user can use the accumulated points to purchase products and receive other services.

  The point card 10 may take any form, for example, a card type or an information terminal such as a smartphone. Unique identification information for identifying the user is registered in the point card 10. For example, when points to the point card 10 are given at a terminal on the store side, purchase information on the user's products is transmitted to the server 20. Is done. The purchase information includes, for example, a product purchased by the user, a purchase date and time, a purchase store, and the like. Alternatively, in another aspect, when the point card 10 has a communication function like a smartphone, the point card 10 itself may transmit purchase information to the server 20 together with user identification information.

  FIG. 2 shows a functional configuration example of the server 20. When a product is purchased at a store where the point card 10 is used, the server 20 generates purchase history information for each user based on the purchase information receiving unit 22 that receives the purchase information and the received purchase information. Purchase history information storage unit 24 and purchase history information transmission unit 26 that transmits purchase history information in response to a request from the user.

  FIG. 3 is a block diagram illustrating a configuration example of the in-vehicle device 30. The in-vehicle device 30 according to the present embodiment includes an input unit 100, a position information calculation unit 110, a navigation unit 120, a display unit 130, an audio output unit 140, a communication unit 150, a storage unit 160, and a control unit 170. . However, this configuration is an example.

  The input unit 100 receives an instruction from the user through an input key device, a voice input recognition device, a touch panel, and the like, and provides this to the control unit 170. The position information calculation unit 110 calculates the current location of the host vehicle based on GPS signals transmitted from GPS satellites and sensor outputs of gyro sensors and acceleration sensors mounted on the vehicle. For example, the navigation unit 120 searches for a route from the current position to the destination and guides the searched route, or causes the display unit 130 to display a road map around the vehicle position.

  The display unit 130 includes a liquid crystal display having a touch panel function and other display devices. For example, a setting screen for displaying a road map image generated by the navigation unit 120 and setting a destination of the in-vehicle device 30. Or display the menu screen. Furthermore, in this embodiment, as will be described later, a guide for preventing forgetting to purchase a product that is regularly purchased is displayed. The voice output unit 140 outputs music data read from the storage unit 170, guidance voice for guiding the guidance route calculated by the navigation unit 120, and the like. Further, in the present embodiment, as will be described later, a guidance for preventing forgetting to purchase a product that is regularly purchased is output by voice.

  The communication unit 150 enables wireless or wired data communication with an external device or an external network. As described above, the communication unit 150 performs wireless communication with the server 20 and can acquire purchase history information and the like from the server 20. Further, for example, as shown in FIG. 4, the communication unit 150 can access the position information distribution site (or distribution server) 152 via the network NW and acquire the vehicle position information therefrom. In this case, position calculation using a GPS satellite by the position information calculation unit 110 or position calculation using a self-contained navigation sensor is not necessarily essential. Further, the communication unit 150 can access the map data distribution site 154 via the network NW and acquire necessary map data therefrom. In this case, the storage unit 160 does not necessarily need to store a large amount of map data, and can download necessary map data as needed via the network NW and hold it. Further, the communication unit 150 can access the store information distribution site 156 via the network NW, search for a necessary store there, and acquire the store information. For example, it is possible to search for stores included in the purchase history information, stores of the same series, stores having the same genre, and the like.

  The storage unit 160 can store application software or a program executed by the control unit 170, map data required by the navigation unit 120, and the like. FIG. 5 shows an example of map data. The map data 162 includes link data 164, node data 166 and facility data 168. The link data 164 is data relating to a road that connects the intersection and the intersection, and includes the longitude and latitude of the start point and the end point of the road and the attributes of the road (for example, type, width, regulation, etc.). The node data 166 includes an intersection node flag indicating whether or not the node is an intersection, a connection relationship between an entrance link to the intersection and an exit link exiting from the intersection. The facility data 168 includes a facility name, a facility position (latitude and longitude), a facility genre (category), a facility attribute, and the like. Facilities are classified into genres such as stores, restaurants, and gas stations, for example. Furthermore, stores, restaurants, gas stations, etc. can be further classified into genres or categories. For example, for stores, stores can be categorized by type (convenience store, department store, discount store, major mass retailer), by capital relationships such as chain stores or franchise, or by name. is there.

  In a preferred embodiment, the control unit 170 includes a microcontroller including a ROM, a RAM, and the like, and the ROM or the RAM can store various programs for controlling the operation of each unit of the in-vehicle device 30. In the first embodiment, the control unit 170 executes a product purchase guidance program 200 that provides purchase guidance for products presumed to be purchased. For example, the product purchase guide program 200 is executed when the navigation unit 120 is operated.

  FIG. 6 is a diagram illustrating a functional configuration example of the product purchase guide program 200 according to the first embodiment. The product purchase guidance program 200 includes a purchase history information request unit 210, a purchase history information acquisition unit 220, a next purchase product estimation unit 230, a purchase date estimation unit 240, a purchaseable store determination unit 250, and a purchase guidance unit 260. The

  The purchase history information request unit 210 requests purchase history information of a specific user from the server 20 via the communication unit 150. When requesting purchase history information, if identification information for identifying a user is necessary, the identification information is transmitted to the server 20. The identification information may be registered in the in-vehicle device 30 in advance, or may be input by the user via the input unit 100. Further, the timing requested by the purchase history information requesting unit 210 is not particularly limited. For example, when the in-vehicle device 30 is activated, the navigation unit 120 performs route guidance to the destination. Can be done.

  As described above, the server 20 manages the purchase history information for each user, and updates the purchase history information every time the point card 10 is used. FIG. 7A shows an example of purchase history information. As shown in the figure, the purchase history information includes a purchase product name, purchase date / time, purchase store name, and purchase store location information. Note that the location information of the purchase store is not essential but arbitrary. The purchased product name represents the name of a product purchased in the past by a specific user (hereinafter sometimes referred to as user X), and the purchase date / time represents the date / time when the product was purchased. In FIG. 7A, for convenience, the date and time (first purchase date, second purchase date, and third purchase date) when purchased three times in the past are shown, but this is merely an example. The first purchase date is the latest purchase date, the second purchase date is the second newest purchase date, and the third purchase date is the third newest purchase date. The purchased store name is a store where the product is purchased, in other words, a store where a point card is used. When the location information of the purchase store name is available, the location information is stored together.

  The purchase history information transmission unit 26 of the server 20 transmits purchase history information to the in-vehicle device 30 in response to a request from the purchase history information request unit 210, and the purchase history information acquisition unit 220 purchases the purchase history via the communication unit 150. Get information. The acquired purchase history information is provided to the next purchase product estimation unit 230, the purchase date estimation unit 240, the purchase available store determination unit 250, and the like.

  The next purchase product estimation unit 230 estimates a product that needs to be purchased next time based on the purchase history information acquired by the purchase history information acquisition unit 220. In one example, the next purchase product estimation unit 230 extracts a product that is included in the purchase history information and has a plurality of purchase histories in the past. If the product has been purchased multiple times in the past, it is presumed that the product needs to be purchased next time. In addition, the number of purchases in the past can be set as appropriate. If the number of purchases is large, the possibility of purchase next time is higher. Moreover, you may make it extract the goods purchased several times within the past fixed period from purchase history information. This is because when the purchase date and time is old, the purchase tendency of the product may be changed. In the example of FIG. 7A, the next purchase product estimation unit 230 needs to purchase “toilet paper”, “detergent”, “toothpaste”, and “trash bag” purchased multiple times in the past. Select as a product to be sold. The result estimated by the next purchase product estimation unit 230 is provided to the purchase date estimation unit 240.

  The purchase date estimation unit 240 estimates the purchase date of the product estimated by the next purchase product estimation unit 230 based on the purchase history information. In one example, the purchase date estimation unit 240 calculates a cycle of a plurality of past purchase dates, and estimates a purchase date from the cycle. In the example shown in FIG. 7A, a purchase cycle is calculated from “first purchase date”, “second purchase date”, and “third purchase date”. For example, the purchase cycle of “toilet paper” is one month. Therefore, it can be estimated that the next purchase date is May 3, 2015, one month after the first purchase date. In the case of “detergent” and “toothpaste”, the purchase cycle is not necessarily constant but irregular. In such a case, for example, an average value of the difference between the first purchase date and the second purchase date and the difference between the second purchase date and the third purchase date can be set as the purchase cycle. If the purchase is made only twice, such as “trash bag”, the difference between the first purchase date and the second purchase date is taken as the purchase cycle. Further, the purchase date estimation unit 240 does not necessarily require the purchase date to be one day. For example, when there are variations in the purchase cycle, the estimated purchase dates may be a plurality of dates.

  Further, the purchase date estimation method is not limited to this, and other methods can be used or combined. For example, when the purchase dates of past products are concentrated on the first Friday of every month, the purchase cycle is not calculated, but the purchase date is concentrated (the first day of each month). (Friday of the week) can be estimated as the purchase date. Alternatively, when purchase dates of past products are concentrated on general holidays such as Saturday, Sunday, and holidays, the holidays can be estimated as purchase dates. In this case, the purchase date can be estimated in combination with the purchase cycle described above.

  The purchaseable store determination unit 250 determines a store where the product estimated by the next purchase product estimation unit 220 can be purchased. Specifically, the purchaseable store determination unit 250 searches for a purchaseable store from the facilities included in the facility data 168 (FIG. 5) based on the purchase store name included in the purchase history information or its position information. When the purchase history information includes only the name of the store to be purchased, the purchaseable store determination unit 250 searches for a store having the same name from the facility data, and determines that the searched store is a store that can be purchased. Further, when the purchase history information includes the name of the purchase store and the position information thereof, the corresponding store may be searched from the position information. When a matching store is found, the attribute information of the store (store genre, category, presence / absence of affiliated store, etc.) is extracted simultaneously. In addition, when the store can be searched from the facility data 168, the store available for purchase determination unit 250 searches the store information distribution site 156 via the communication unit 150 using the name of the store to be purchased as a keyword, You may make it acquire a shop and its attribute information.

  In one example, the purchaseable store determination unit 250 determines that a store having the same name as the purchase store included in the purchase history information can be purchased, and further stores having the same attributes as the purchase store, for example, the same series and the same A store of genre, same type, same capital, etc. is determined as a store that can be purchased. FIG. 7B is an example of a shop that can be purchased determined based on the purchase history information shown in FIG. “Toilet paper”, which is the next purchase, is purchased at drugstore A and supermarket A, so it is purchased by stores with the same name, and pharmacies and major mass retailers that have the same attributes as drugstore A and supermarket A It is determined as a possible store. In addition, for the “trash bag” that is the next purchase product, it is determined that the convenience store A and the convenience store having the same attribute are purchaseable stores.

  Further, the purchaseable shop determination unit 250 determines whether or not there is a shop that can be purchased around the vehicle position calculated by the vehicle position calculation unit 110 with reference to the map data. For example, when the next purchase product is “toilet paper” shown in FIG. 7B, the store available for purchase determination unit 250 has a drug store A / super A or pharmacy / It is determined whether there is a major mass retailer. The determination result of the purchaseable store determination unit 250 is provided to the purchase guide unit 260.

  The purchase guidance unit 260 provides purchase guidance for the next purchase product based on the estimation result of the purchase date estimation unit 240 and the determination result of the purchase available store determination unit 250. Purchase guidance is performed via the display unit 130 and / or the audio output unit 140. FIG. 8 is a specific guidance example of the purchase guidance unit 260 according to the present embodiment, and a message indicating that there is a purchaseable product is displayed on the screen of the display unit 130. Voice guidance such as “There are products available” is given. Further, the display unit 130 may display a selection button 132 for displaying a store that can be purchased or a route search up to that point. When the user desires to display a store that can be purchased via the selection button 132, the store that can be purchased is displayed on the road map of the display unit 130, and the destination may be set from the displayed store. .

  Next, the operation of the merchandise purchase guidance system of the present embodiment will be described with reference to the flow of FIG. First, when the user X purchases a product at a store and the point card 10 is used, purchase information is transmitted from the store to the server 20. The purchase information is received by the purchase information receiving unit 22 (S100), and the purchase history information is generated and stored by the purchase history information storage unit 24 (S102). Thereafter, when the in-vehicle device 30 is operated, the purchase history information request unit 210 requests the purchase history information of the user X (S104), and the purchase history information transmission unit 26 responds to the request with reference to FIG. The purchase history information as shown in (A) is transmitted to the in-vehicle device 30 (S106), and the purchase history information acquisition unit 220 completes the acquisition of purchase history information (S108).

  When the purchase history information is acquired, the next purchase product estimation unit 220 estimates a product that needs to be purchased next time based on the purchase history information (S110). The date estimation unit 240 estimates the purchase date of the next purchased product (S112). When there are a plurality of items for purchase next time, the purchase date of each item is estimated. Next, the purchaseable store determination unit 250 determines whether there is a store that can be purchased in the vicinity of the vehicle position (S114). When it is determined that there is a store that can be purchased, the purchase guide unit 260 determines whether or not the purchase date estimated by the purchase date estimation unit 240 corresponds (S116). Next, the next purchased product is guided (S118). When there is no next time purchase product, there is no store available for purchase, or when the purchase date does not correspond, the product purchase guidance is not performed (S120).

  As described above, according to the first embodiment, when there is a shop that can be purchased in the vicinity of the own vehicle position and it corresponds to the purchase date, the purchase guidance for the next purchase product is performed. You can purchase necessary products at stores.

  Further, in the present embodiment, when the destination is not set, when the own vehicle arrives at the purchaseable store determined by the purchaseable store determination unit 250, the purchase guide unit 260 guides the next purchase product. You may make it do. In this case, when the user arrives at the store, the purchase guidance for the next purchase product is provided, so that the necessary product can be purchased with certainty.

  Next, a second embodiment of the present invention will be described. In the first embodiment, an example in which purchase guidance is performed when a store that can be purchased exists near the vehicle position (or the current location) is shown. In the second embodiment, the purchase is made near the set destination. When there is a store available, purchase guidance is provided. In addition, about the same structure as the goods purchase guidance system 1, the server 20, and the vehicle-mounted apparatus 30, the same reference number is attached | subjected and description is abbreviate | omitted.

  FIG. 10 is a diagram illustrating a functional configuration example of the purchase guide program 200A according to the second embodiment. The purchase guidance program 200A according to the second embodiment includes a destination information acquisition unit 205 in addition to the case of the first embodiment. The destination information acquisition unit 205 acquires position information when the user sets a destination in the navigation unit 120. This position information is provided to the purchaseable shop determination unit 250.

  The purchaseable store determination unit 250 determines whether there is a purchaseable store near the destination acquired by the destination information acquisition unit 205. When it is determined that there is a shop that can be purchased and the purchase date corresponds to the purchase date of the next purchase product, the purchase guide unit 260 provides purchase guidance in relation to the destination setting screen or the destination setting screen. . Further, purchase guidance can be given when it is determined that the vehicle position has reached the destination.

  Next, the operation of the merchandise purchase guidance system according to the second embodiment of the present invention will be described with reference to the flow of FIG. Steps S100 to S112 are the same as the steps shown in FIG. In the second embodiment, a destination is set in the in-vehicle device 30 (S150). The destination setting timing is not particularly limited, and may be performed after requesting purchase history information. When the destination is set, the destination information is acquired by the destination information acquisition unit 205, and the acquired destination information is provided to the purchaseable store determination unit 250. The purchaseable store determination unit 250 determines whether there is a purchaseable store near the destination, for example, within a certain distance from the destination (S152). When it is determined that there is a store available for purchase, the purchase guide unit 260 determines whether or not the purchase date estimated by the purchase date estimation unit 240 is satisfied (S154). Purchase guidance is provided for (S156). Purchase guidance may be performed in association with the destination setting screen, or may be performed simultaneously with arrival guidance when arriving at the destination. On the other hand, when there is no store that can be purchased or when the purchase date does not correspond, the next purchased product is not guided (S158).

  In this way, in the second embodiment, when there is a store that can be purchased at or near the destination set by the user, the purchase guidance for the next purchase product is performed, so at the timing of going to the destination, At the same time, it is possible to encourage the purchase of goods.

  Next, a third embodiment of the present invention will be described. In the third embodiment, when arriving at the destination and re-departing from the destination, it is determined whether or not the next purchase item has been forgotten to be purchased. Do. FIG. 12 is a diagram illustrating a functional configuration example of the purchase guide program 200B according to the third embodiment, which includes a restart detection unit 270 and an update request unit 280 in addition to the configuration of the second embodiment. Consists of.

  The restart detection unit 270 detects whether or not the vehicle departs from the destination. For example, the restart detection unit 270 detects the restart of the destination when the engine is once turned off after the arrival at the destination and the engine is started again. Alternatively, the restart detection unit 270 simply detects restart when it is determined that the vehicle position has reached the destination and the vehicle position is away from the destination by a certain distance. The update request unit 280 causes the purchase history information request unit 210 to execute a request for purchase history information when a restart is detected by the restart detection unit 270. As a result, the latest purchase history information is acquired by the purchase history acquisition unit 220, and the next purchase product estimation unit 230, the purchase date estimation unit 240, and the purchaseable shop determination unit 250 are based on the latest purchase history information. Estimate or determine the purchase date and the presence or absence of a store available for purchase.

  The purchase guidance unit 260 compares the next purchase product that was purchased at the time of destination setting or arrival at the destination with the next purchase product updated at the time of departure, and if the number of both matches, If it is determined that the next-purchased product has not been purchased at a purchaseable store near the destination, and the number of both has decreased, it is determined that the next purchased product has been purchased at a purchaseable store near the destination. If it is determined that the next purchase product is not purchased in the vicinity of the destination, the purchase guide unit 260 performs purchase guidance again to check whether the next purchase product is forgotten.

  FIG. 13 is a flowchart showing the operation of the third embodiment, in which purchase guidance for the in-vehicle device 30 is shown. As described in the second embodiment, when there is a shop that can be purchased near the destination and the purchase date falls, purchase guidance for the next purchase product is performed (S200). Next, the restart detection unit 270 detects whether or not the own vehicle restarts the destination (S202). When a restart is detected, the update request unit 280 causes the purchase history information request unit 210 to request purchase history information (S204). In response to this request, the latest purchase history information is transmitted from the server 20 to the in-vehicle device 30, and the latest purchase history information is acquired by the purchase history information acquisition unit 220 (S206). The next purchase product and purchase date are estimated based on the latest purchase history information, and the purchase available store determination unit 250 determines the purchase available store.

For example, as in the second embodiment, when the user arrives at the destination setting screen or at the destination, guidance is given for the next purchase item at a shop available for purchase near the destination, and travel until the destination is reached. As shown in the first embodiment, if there is a store that can be purchased near the location of the vehicle, purchase guidance for the next purchase product is provided there, and when the destination is restarted, As such, if there is a forgotten purchase of the next purchased product, purchase guidance is provided there.
Further, as a modification of the second embodiment, when a route to the destination is searched for in the navigation unit 120, it is determined whether there is a shop that can be purchased near the searched route, and purchase guidance for the next purchase product It is also possible to perform. In this case, purchase guidance may be performed on the destination setting screen, or purchase guidance may be performed while the vehicle is traveling on the route.

  Further, as illustrated in FIG. 14A, the in-vehicle device 10 may be connected to an information terminal such as a smartphone S and perform data communication with the server 20 or another network via the smartphone S. . In this case, the smartphone S may appropriately acquire the purchase history information from the server 20 and provide the acquired purchase history information to the in-vehicle device 30. Or when the information terminal like the smart phone S is equipped with the navigation function, the smart phone S can be used as the in-vehicle device 30 as shown in FIG.
