<B. Second Embodiment>
FIG. 3 is a functional block diagram of the product information display control apparatus 102 according to the second embodiment. The merchandise information display control device 102 is a navigation device mounted on a vehicle, for example. The product information display control device 102 includes an operation accepting unit 16, a route search unit 17, a position acquisition unit 18, and a map data storage unit 19 in addition to the configuration of the product information display control device 101 according to the first embodiment. The product information display control device 102 includes a product information management unit 122 instead of the product information management unit 12 of the product information display control device 101. The merchandise information display control device 102 is connected to the display device 31, the input device 32, and a GPS (Global Positioning System) receiver 33, and is configured to be able to use them.

  In addition to the product information database 13, the product information management unit 122 has a designated product list 13A and a purchase proposal product list 13B. When the display product information determination unit 14 acquires the product information from the product information acquisition unit 11, the display product information determination unit 14 registers the product information in the product information database 13 and creates a designated product list 13 </ b> A and a purchase proposal product list 13 </ b> B based on the product information database 13 or Update.

  The input device 32 is a device used by the user to perform an input operation on the product information display control device 102. The input device 32 is, for example, a mechanical button or a touch panel provided on the housing of the product information display control device 102. When the input device 32 is realized by a touch panel, the input device 32 and the display device 31 may be integrally configured as a touch screen. The operation receiving unit 16 receives a user input operation from the input device 32. The user input operation received by the operation receiving unit 16 is, for example, a setting operation for a designated product, a display operation for the purchase proposal product list 13B, a correction operation for the purchase proposal product list 13B, or the like. The details of each operation will be described later.

  The GPS receiver 33 is mounted on the vehicle and receives GPS signals. The position acquisition unit 18 acquires a GPS signal from the GPS receiver, and grasps the current position of the vehicle based on the GPS signal. Here, the GPS signal is taken as an example, but the position acquisition unit 18 may also use signals of a gyro sensor or a vehicle speed sensor, and the position information obtained based on these signals is corrected by map mapping. May calculate the current position of the vehicle.

  The route search unit 17 acquires vehicle position information from the position acquisition unit 18, map data from the map data storage unit 19, and position information of the store at the waypoint or destination from the display product information determination unit 14. Based on the current location of the vehicle, a route from the desired store to the transit location or destination is searched. The route searched by the route search unit 17 is sent to the display control unit 15 and displayed on the display device 31 as necessary.

  FIG. 4 is a flowchart showing the operation of the product information display control apparatus 102. Hereinafter, the operation of the merchandise information display control apparatus 102 will be described with reference to FIG.

  The flow of FIG. 4 starts, for example, when the accessory power supply of the vehicle is turned on or when a purchase proposal request is input to the product information display control device 102. The purchase proposal request to the product information display control apparatus 102 is acquired by the operation reception unit 16 when the user presses a “purchase button” that is the input device 32, for example.

  First, the position acquisition unit 18 acquires the current position information of the vehicle (step S201).

  Next, the product information acquisition unit 11 acquires the product information of the designated area from a web flyer or a web page of each store (step S202). Here, the designated area which is a geographical range from which the product information is acquired is set in advance by the user, for example. The user can set a vicinity of a frequently staying point, such as a surrounding area of a home or work, as a designated area, or set a periphery of a route between the home and the work as a designated area. Thereby, the user can obtain a purchase proposal for a store that is close to the daily activity range, and can increase the options of the purchased store if the store that received the purchase proposal has never been. . Alternatively, the product information acquisition unit 11 may set the designated area based on the current location of the vehicle acquired by the position acquisition unit 18 in step S201. For example, the merchandise information acquisition unit 11 may set a range with a radius of 3 km centered on the current location of the vehicle as the designated area.

  The product information includes information on a store that sells the designated product in the designated area and information on the sales price of the designated product at the store. The designated product is a product designated by the user as a product for which product information is desired to be provided. For example, it is desirable to purchase daily necessities such as detergents and toilet paper at as low a price as possible even if they are not needed immediately. Therefore, the user sets the daily necessities as described above as designated products.

  FIG. 5 illustrates the designated product list 13A. The designated product list 13A includes items such as category, product name, manufacturer, and type as specific items of the designated product, and items such as the lowest price (including tax), update date, and store name as other items. The designated product is set when the user inputs information for specifying the designated product in the designated product list 13A. The designated product list 13 </ b> A may be imported from the PC to the product information display control device 102 after the user has created it with an external device such as a personal computer (PC) in accordance with the format defined by the product information display control device 102. Alternatively, the designated product list 13 </ b> A can be created by the user directly inputting the product information display control device 102 using the input device 32.

  When the designated product is set as described above, the display product information determination unit 14 extracts the lowest price of the designated product, the sales time at the lowest price, and the store selling at the lowest price from the product information database 13. These pieces of information are entered in the items of the lowest price (including tax), the update date, and the store name in the designated product list 13A.

  Assuming that the designated product list 13A thus created is already stored in the product information management unit 122, the display product information determination unit 14 in step S203 of FIG. It is determined whether or not there is product information indicating a sales price equal to or lower than the lowest price in the product list 13A. For example, if the newly acquired product information is “product name: toilet paper, type: single 12 rolls, sales price: 328 yen, store name: A”, the specified product list 13A in FIG. Since the cheapest price is 318 yen, the determination in step S203 is No. In this case, the product information display control device 102 does not update the designated product list 13A and ends the process without creating the purchase proposal product list 13B. On the other hand, if the newly acquired product information is “Product name: Toilet paper, Type: Single 12 roll, Sales price: 298 yen, Store name: C”, the sales price is below the lowest price and the determination in step S203 Becomes Yes. In this case, the display product information determination unit 14 updates the designated product list 13A (step S204).

  FIG. 6 shows the designated product list 13A after the update in step S204. In the example of FIG. 6, the use date of the user is 2017/12/23. Comparing the designated product list 13A in FIG. 6 with the designated product list 13A in FIG. 5, in the designated product list 13A in FIG. 6, the lowest price of toilet paper is from 318 yen to 298 yen, and the update date is from 2017/11/21. On 2017/12/23, the store name is updated from C to A, respectively. In addition, in the designated product list 13A of FIG. 6, the lowest price etc. are similarly updated about shampoo and foundation. For the foundation, since the selling price in the newly acquired product information is the same as the lowest price, the designated price list 13A in FIG. 6 is updated with the lowest price unchanged from the designated price list 13A in FIG. Only the day has been updated.

  Further, the display product information determination unit 14 extracts only the information on the designated product updated in step S204 from the designated product list 13A, and creates the purchase proposal product list 13B (step S205). FIG. 7 shows a purchase proposal product list 13B created by extracting from the designated product list 13A of FIG. The product information shown in the purchase proposal product list 13B in FIG. 7 is display product information to be displayed to the user. In this way, the display product information determination unit 14 determines the product information whose sales price indicated by the product information is equal to or lower than the lowest price as display product information. When the purchase proposal product list 13B is displayed on the display device 31, the rectangular mark in the column “map” at the right end of the purchase proposal product list 13B displays the map information of the store when the mark is touched. It is shown that.

  Next, the route search unit 17 searches for a route whose destination or destination is the store indicated in the purchase proposal product list 13B (step S206). Since the stores shown in the purchase proposal product list 13B in FIG. 7 are A and C, the route search unit 17 follows the store A and the store C from the current location H of the vehicle, for example, as shown in FIG. Search for a route back to Although FIG. 8 shows a route back to the current location, the final point can be changed to an arbitrary location such as home according to the user's setting.

  Next, the display control unit 15 acquires the route searched in step S206 from the route search unit 17, acquires the purchase proposal product list 13B from the display product information determination unit 14, and displays them on the display device 31 (step S31). S207). That is, in this step, the purchase proposal product list 13B of FIG. 7 and the route of FIG. Thereby, the user can grasp | ascertain the route to the store which can purchase the designated goods of the cheapest price and designated goods at the cheapest price. When there are a plurality of routes that satisfy the condition in step S206, the plurality of routes may be displayed in step S207, or only one route may be displayed. Further, the user may select whether to display a plurality of routes or only one route.

  Next, the operation reception unit 16 determines whether or not there is an operation for correcting the purchase proposal product list 13B by the user (step S208). The user can correct the purchase proposal product list 13 </ b> B by operating the input device 32. For example, when the user wants to go only to the store C, as shown in FIG. 9, an operation of clearing a check box in the shampoo purchase column is performed. In this case, the display product information determination unit 14 deletes the shampoo information from the purchase proposal product list 13B as shown in FIG. 10 (step S209). In this way, the user can select the products to be purchased on the day from the purchase proposal product list 13B. Therefore, for example, by removing from the purchase proposal product list 13B so as not to purchase a product that the user has a large amount of stock and is considered unnecessary for a while, it is possible to suppress an unnecessary drop-in at a store.

  Furthermore, the route search unit 17 searches for a route again based on the corrected purchase proposal product list 13B (step S209). Since the store shown in the purchase proposal product list 13B in FIG. 10 is only the store C, the route search unit 17 searches for a route that travels back and forth from the current location H of the vehicle, for example, as shown in FIG. Then, the display control unit 15 acquires the route searched in step S209 from the route search unit 17, acquires the corrected purchase proposal product list 13B from the display product information determination unit 14, and causes the display device 31 to display these. (Step S210). Although FIG. 11 shows a route back to the current location, the final point can be changed to an arbitrary place such as a home according to the user's setting.

  When there is no correction operation of the purchase proposal product list 13B by the user in step S208, the product information display control apparatus 102 ends the process.

  As described above, according to the product information display control apparatus 102, the designated product list 13A is created from the product information database 13 in which product information acquired in the past is accumulated. In the designated product list 13A, the cheapest price of the designated product in a certain period such as the past year is described. When the sales price of the newly acquired product information is equal to or lower than the lowest price in the designated product list 13A, the product information of the designated product that is lower than the lowest price is displayed to the user as the purchase proposal product list 13B. Therefore, the user can receive a notification from the product information display control device 102 when the designated product registered in advance reaches the lowest price, and can purchase the designated product at an appropriate timing. .

  In the flow of FIG. 4, it is shown that a route having a store on the purchase proposal product list 13 </ b> B as a transit point or a destination is searched (steps S <b> 206 and S <b> 209). By displaying to the user a route whose destination is the store listed in the purchase proposal product list 13B, the user can easily grasp the route to the store where the specified product can be purchased at the lowest price. it can. However, the merchandise information display control apparatus 102 may only display the purchase proposal merchandise list 13B on the display device 31 without performing the route search. Even in this case, the user can grasp the designated product that has the lowest price and the information of the store that sells the designated product at the lowest price from the purchase proposal product list 13B.

  Further, in the present embodiment, it has been described that the designated product list 13A is created from the product information in the product information database 13, and is updated as needed each time new product information is acquired. However, the product information in the product information database 13 used for the designated product list 13A may be limited to information for a certain period, such as within the past year. That is, when the cheapest price in the designated commodity list 13A becomes information more than one year ago, the displayed commodity information determination unit 14 deletes the cheapest price and extracts the cheapest price from commodity information within the past year. The designated product list 13A is updated. By excluding too old product information from the designated product list 13A, it becomes possible to suppress the influence of price fluctuations.

  In the present embodiment, when the sales price indicated by the product information is equal to or lower than the lowest price, the product information is added to the purchase proposal product list 13B. However, as a condition for adding the product information to the purchase proposal product list 13B, whether the selling price is equal to or lower than the lowest price is an example. For example, the condition that the product information is added to the purchase proposal product list 13B may be that the sales price indicated by the product information is 110% or less of the lowest price. In any case, the product information may be added to the purchase proposal product list 13B based on the comparison between the sales price indicated by the product information and the lowest price.

  In the present embodiment, the sales price indicated by the product information is compared with the lowest price in the designated product list 13A, and if the sales price indicated by the product information is equal to or lower than the lowest price, the designated product list 13A is updated. explained. However, the price to be compared here may be a price per unit amount. However, in this case, it is assumed that the product information includes information on the amount of the product such as “single 12 rolls” for toilet paper and “380 ml” for shampoo. A unit quantity is determined for each designated product in advance, and the display product information determination unit 14 registers the lowest price per unit quantity in the designated product list 13A.

  The unit amount is, for example, 1 roll or 1 meter for toilet paper, 1 box or 1 for box tissue, 1 gram for liquid detergent, 1 for stick sugar, 1 gram for sugar , Etc. Then, the display product information determination unit 14 converts the sales price indicated by the product information newly acquired by the product information acquisition unit 11 into the sales price per unit amount, and then per unit amount registered in the designated product list 13A. Compare with the lowest price. After comparing the selling price and the cheapest price indicated by the product information with the price per unit quantity, the price of the same designated product with a different quantity is accurately determined by updating the cheapest price in the designated product list 13A. Can be compared.

<C. Embodiment 3>
In the second embodiment, it is assumed that the sales time indicated by the product information newly acquired by the product information acquisition unit 11 is that of today. However, in the third embodiment, it is assumed that product information indicating the future sales time is included in the product information newly acquired by the product information acquisition unit 11. In the following description, the product information indicating the future sales time is referred to as future product information, and the product information indicating the current sales time is referred to as current product information to distinguish between the two.

  When the product information acquisition unit 11 acquires both current product information and future product information, even if the sales price indicated by the current product information is less than or equal to the lowest price, future product information related to the specified product that is the same as the current product information The selling price indicated by may be even cheaper. In such a case, if the current product information is included in the purchase proposal product list 13B and proposed to the user, the user may miss the opportunity to purchase the designated product at a lower price in the future. Therefore, the display product information determination unit 14 has the current product information indicating the sales price below the lowest price for the same designated product and the future product information indicating the sales price lower than the current product information. It is determined that the current product information is not added to the purchase proposal product list 13B.

  This determination process is executed between step S202 and step S203 of the flow of the second embodiment shown in FIG. FIG. 12 is a flowchart illustrating a determination process related to future product information by the display product information determination unit 14.

  In the flow of FIG. 12, the display product information determination unit 14 first determines whether or not future product information is included in the product information newly acquired by the product information acquisition unit 11 (step S301). If there is no future product information in the newly acquired product information, the processing of the product information display control apparatus 102 proceeds to step S203.

  When the future product information is included in the newly acquired product information, the display product information determination unit 14 determines whether the sales price indicated by the future product information is equal to or lower than the lowest price in the designated product list 13A ( Step S302).

  When the sales price indicated by the future product information is higher than the lowest price in the designated product list 13A, the processing of the display product information determination unit 14 proceeds to step S305. In this case, the display product information determination unit 14 excludes only the future product information from the determination target in step S203 (step S305).

  When the sales price indicated by the future product information is less than or equal to the lowest price in the designated product list 13A, the displayed product information determination unit 14 determines that the current product information is the same as the future product information and the designated product and has a higher sales price. It is determined whether or not there is (step S303). If there is no current product information in which the future product information is the same as the designated product and the selling price is higher than that, the process of the display product information determination unit 14 proceeds to step S305. In this case, the display product information determination unit 14 excludes only the future product information from the determination target in step S203 (step S305).

  If there is current product information in which the future product information is the same as the designated product and the selling price is higher than that, the display product information determination unit 14 excludes the current product information from the determination target in step S203 (step S304). And the process of the display merchandise information determination part 14 transfers to step S305.

  As described above, in the product information display control apparatus according to the third embodiment, the product information includes information on sales time, and the displayed product information determination unit 14 is a future product that is product information indicating the future sales time. The product information indicating the current sales period and the product information having the same information as the specified product and having a sales price higher than the future product information is excluded from the items to be added to the purchase proposal product list 13B as the display product information. . As a result, it is possible to avoid presenting the user with the current lowest price of the designated product that can be purchased at a lower price in the future. When the sales price indicated by the current product information is equal to or lower than the lowest price and the future product information indicates a sales price lower than the sales price, the display control unit 15 displays the future product information as a pop-up or a telop. May be displayed on the display device 31 in the form of Thereby, the user can grasp | ascertain that the designated goods can be purchased cheaply in the future.

The transmission process of the purchase proposal product list 13B by the communication unit 20 is executed between step S207 and step S208 of the flow of the second embodiment shown in FIG. FIG. 14 is a flowchart showing the transmission process of the purchase proposal product list 13B by the communication unit 20.

  In the flow of FIG. 14, the communication unit 20 first determines whether it is pairing with the user terminal 34 (step S501). Here, it is assumed that the communication unit 20 and the user terminal 34 perform wireless communication such as Bluetooth (registered trademark). However, in the case of a wired connection, the communication unit 20 determines whether or not the user terminal 34 is connected. to decide.

  If the communication unit 20 is not pairing with the user terminal 34, the processing of the product information display control device 104 proceeds to step S208. On the other hand, if the communication unit 20 is pairing with the user terminal 34, the communication unit 20 transmits the purchase proposal product list 13B to the user terminal 34 (step S502).

  According to the flow of FIG. 14, the communication unit 20 transmits the purchase proposal product list 13 </ b> B to the user terminal 34 without an input operation from the user. However, as illustrated in FIG. 15, the communication unit 20 may transmit the purchase proposal product list 13 </ b> B to the user terminal 34 in accordance with an input operation from the user.

  After displaying the route and the purchase proposal product list 13B on the display device 31 (step S207 in FIG. 4), the product information display control device 104 determines whether there is a list transmission request from the user in the flow in FIG. Judgment is made (step S601). The list transmission request to the merchandise information display control device 104 is acquired by the operation reception unit 16 when the user presses a “list transmission button” that is the input device 32, for example.

  If there is a list transmission request from the user, it is determined whether the communication unit 20 is pairing with the user terminal 34 (step S602). If the communication unit 20 is not pairing with the user terminal 34, the display control unit 15 causes the display device 31 to display a pairing request notification screen (step S603). The pairing request notification screen is a notification screen that prompts the user to pair the product information display control device 104 and the user terminal 34.

  As described above, the product information display control apparatus 104 according to the fourth embodiment includes the communication unit 20 that transmits the purchase proposal product list 13B, which is a list of display product information, to the user terminal 34. Therefore, according to the product information display control device 104, it is possible to transmit the purchase proposal product list 13B to the user terminal 34. Therefore, the user can perform shopping while confirming the purchase proposal product list 13 </ b> B using the user terminal 34.

<E. Embodiment 5>
FIG. 16 is a functional block diagram of the merchandise information display control apparatus 105 according to the fifth embodiment. The merchandise information display control device 105 is a navigation device mounted on a vehicle, for example. The product information display control device 105 includes a price fluctuation information acquisition unit 21 in addition to the configuration of the product information display control device 104 according to the fourth embodiment.

  The price fluctuation information acquisition unit 21 acquires price fluctuation information of a product from news on the Internet, for example. The price fluctuation information includes the price fluctuation amount and the price fluctuation direction of the product.

  The display merchandise information determination unit 14 acquires price fluctuation information from the price fluctuation information acquisition unit 21, and corrects the lowest price of the designated merchandise list 13A based on the price fluctuation information.

  FIG. 17 is a flowchart showing a process of correcting the cheapest price of the designated product list 13A based on price fluctuation information. First, the price fluctuation information acquisition unit 21 acquires price fluctuation information (step S701). This price fluctuation information indicates a price fluctuation product, a price fluctuation amount, and a price fluctuation direction. In the news, price fluctuations may be announced by designating product names, but price fluctuations may be announced by designating raw materials for the products. In the latter case, the price fluctuation information acquisition unit 21 may set a commodity related to a raw material for which price fluctuation has been announced as a price fluctuation commodity.

  The displayed product information determination unit 14 compares the price fluctuation product indicated by the price fluctuation information with the designated product listed in the designated product list 13A, and determines whether or not they match (step S702). If the price-change commodity does not match the designated commodity in step S702, the processing of the commodity information display control device 105 ends.

  If the price change product matches the designated product in step S702, the display product information determination unit 14 determines whether the price change amount indicated in the price change information is equal to or greater than a threshold (step S703). This threshold value is predetermined in the display product information determination unit 14 for each designated product, for example. If the price fluctuation amount is less than the threshold value in step S703, the processing of the merchandise information display control device 105 ends.

  If the price fluctuation amount is equal to or greater than the threshold value in step S703, the displayed product information determination unit 14 corrects the cheapest price in the designated product list 13A based on the price fluctuation information (step S704). For example, when the price fluctuation direction is a price surge, the displayed product information determination unit 14 increases the cheapest price in the designated product list 13A by the price fluctuation amount. On the other hand, when the price fluctuation direction is a price drop, the displayed product information determination unit 14 reduces the cheapest price in the designated product list 13A by the price change amount.

  If the lowest price is not corrected according to price fluctuations, the following problems arise. When prices rise, the sales price indicated by the product information does not readily fall below the lowest price, and the product information cannot be provided to the user. Further, when prices fall, product information indicating a selling price that is lower than the lowest price is frequently generated, so that bargain product information at the current prices cannot be provided to the user. However, since the product information display control device 105 corrects the lowest price of the designated product list 13A based on the price fluctuation information, it is possible to provide bargain product information to the user in view of the current price.

  In the flow of FIG. 17, the cheapest price is corrected only when the price fluctuation amount is equal to or greater than the threshold value. However, the threshold price is not set and the cheapest price is corrected if the price fluctuation value fluctuates even slightly. Anyway.

  In the flow of FIG. 17, the display product information determination unit 14 automatically corrects the cheapest price based on the price fluctuation information. However, the user may manually correct the cheapest price, or the user may be able to make fine adjustments after the cheapest price is automatically corrected according to the flow of FIG. In this case, if the user can refer to the lowest price before being automatically corrected, the user can easily return the lowest price to the price before the automatic correction.

  In the flow of FIG. 17, the cheapest price has been corrected in response to price fluctuations, but the product information database 13 may be reset instead of correcting the cheapest price. FIG. 18 is a flowchart showing a reset process of the merchandise information database 13 based on price fluctuations. In the flow of FIG. 18, step S704B is executed instead of step S704 of the flow of FIG. In step S704B, the displayed product information determination unit 14 deletes all product information registered in the product information database 13, that is, resets, and accordingly deletes the lowest price, store name, etc. in the designated product list 13A. However, here, only the product information of the commodity with variable price may be deleted from the product information database 13.

  After the product information database 13 is reset, the display product information determination unit 14 stores the product information newly acquired by the product information acquisition unit 11 in the product information database 13, and the lowest price of the designated product list 13 </ b> A based on the product information database 13. And store name etc. are updated. In this manner, the displayed product information determination unit 14 resets the product information database 13 when price fluctuations occur, and creates the designated product list 13A based on the subsequent product information, thereby affecting the influence of the product information before price changes. This makes it possible to provide users with bargain product information at the current prices.

  The product information database 13 stores product information for the past year, for example. When resetting the product information database 13 in step S704B of FIG. 18, the display product information determination unit 14 may leave the latest product information without erasing all product information for the past year. For example, when the price change indicated by the price change information has already started one month ago, the displayed product information determination unit 14 may delete only the product information more than one month ago from the product information database 13. . Thereby, product information corresponding to the current price is left in the product information database 13.

  As described above, the product information display control apparatus 105 according to the fifth embodiment includes the price fluctuation information acquisition unit 21 that acquires price fluctuation information indicating the price fluctuation direction and the price of the designated goods. Then, the display product information determination unit 14 corrects the lowest price of the designated product based on the price fluctuation information, and determines the display product information based on the comparison between the sales price indicated by the product information and the corrected lowest price. . Therefore, according to the product information display control device 105, it is possible to make a purchase proposal for a bargain designated product in light of the current price in consideration of price fluctuations.

  Further, in the product information display control apparatus 105, the display product information determination unit 14 determines the lowest price of the designated product based on the price fluctuation information when the price fluctuation amount of the designated product indicated by the price fluctuation information is equal to or larger than the threshold value. to correct. In this case, it is possible to prevent the lowest price from being corrected due to slight price fluctuations.

  Alternatively, in the product information display control apparatus 105 according to the fifth embodiment, the display product information determination unit 14 resets the product information database 13 when the price fluctuation amount of the designated product indicated by the price fluctuation information is equal to or greater than the threshold value. Then, the product information database 13 is recreated using the product information acquired by the product information acquisition unit 11. Therefore, according to the product information display control device 105, it is possible to eliminate the influence of the product information before the price change and provide the user with bargain product information at the current price.
