Thereby, the process of step S12 is completed, and the guidance process proceeds from the process of step S12 to the process of step S13.

  In the process of step S <b> 13, the store information DB 5 inputs information on the name and position of a store that sells foods that are insufficient for cooking the menu selected by the user to the list creation unit 52. Thereby, the process of step S13 is completed, and the guidance process proceeds from the process of step S13 to the process of step S14.

  In the process of step S14, the list creation unit 52 provides information on the ingredients and their quantities that are insufficient for cooking the menu selected by the user, and information on the names and positions of the stores that sell the ingredients (store's information). The position, the distance from the home to the store, the required time, etc.) are transmitted to the vehicle 3 used by the user as a shopping list as shown in FIG. In the shopping list shown in FIG. 5, after leaving home, first purchase 1 pack of ¥ 100 eggs, 2 packs of ¥ 150 tofu, and 1/2 radish of ¥ 98 at XX supermarket, Next, it is described that one ¥ 130 bitter gourd at XX greengrocer and two ¥ 200 pumpkins are purchased, and finally three ¥ 150 sword fish are purchased at □□ fish shop. Thereby, the process of step S14 is completed, and the guidance process proceeds from the process of step S14 to the process of step S15.

  In the process of step S <b> 15, the communication unit 24 receives the shopping list transmitted from the list creation unit 52. Thereby, the process of step S15 is completed, and the guidance process proceeds from the process of step S15 to the process of step S16.

  In the process of step S16, the route search unit 21 calculates a shopping route with the store as described in the shopping list and the home as the destination according to the shopping list information received by the communication unit 24, and calculates By displaying the purchased shopping route and the shopping list on the display monitor 22, the user is guided so that the ingredients that are insufficient for cooking the menu selected by the user can be purchased through the optimum traveling route. The shopping list does not need to be displayed on the display monitor 22 at all times, and includes the meaning of confirming the product purchased at the store when the user arrives at the store listed in the shopping list and gets off. Then, it may be displayed on the display monitor 22. Further, the shopping list may be transmitted to a terminal device carried by the user such as a mobile phone so that the user can check the contents of the shopping list even in the store. Thereby, the process of this step S16 is completed and a series of guidance processes are completed.

  In addition, the user decides whether to give priority to one of the priority items of time priority that minimizes the time required for shopping, price priority that lowers the cost required for shopping, and time service priority that prioritizes store time service. It is preferable that the route search unit 21 changes the travel route calculated in the process of step S16 according to the selected item. Hereinafter, the operation of the route search unit 21 when executing this route change process will be described in detail with reference to the flowchart shown in FIG.

  The flowchart shown in FIG. 6 starts when the process of step S15 is completed, and the path change process proceeds to the process of step S21.

  In the process of step S21, the route search unit 21 displays message data on the display monitor 22 so that the user can select which item of time priority, price priority, or time service priority is given priority for shopping. Prompt. Thereby, the process of step S21 is completed, and the path change process proceeds from the process of step S21 to the process of step S22.

  In the processing from step S22 to step S24, the route search unit 21 determines whether the selected priority item is time priority, price priority, or time service priority in response to the user selecting a priority item. . Then, the route search unit 21 performs route change processing in step S25 when the selected item has time priority, processing in step S26 in case of price priority, and processing in step S27 in case of time service priority. To proceed.

  In the process of step S25, the route search unit 21 connects to the store information DB 5 via the communication unit 24, and the distance and arrival time from the user's home to the store listed in the shopping list are the shortest, and shopping Search for a route through which all products listed can be purchased. Specifically, when the products listed in the shopping list are cabbage, salmon, and beef, the route search unit 21 is the position from the home that is the most among the stores that handle these three products. Is extracted from the store information DB 5. For example, when the store information DB 5 is in the form shown in FIG. 3, the cabbage is handled at the A store and the C store, but the route search unit 21 selects the A store with the shorter distance from the home and the required time. To do. However, since the beef can only be purchased at the C store, the route search unit has a shorter shopping time when purchasing cabbage and beef at the C store than through the two stores, the A store and the C store. 21 determines a route so as to purchase cabbage at store C. Similarly, the route search unit 21 extracts the store B with a short distance from the home and the required time. However, since the bag can be purchased at the store C, the route search unit 21 purchases the bag at the store C. Determine the route. As a result, since all the products can be purchased only at the C store, the travel route from the home to the C store as shown in FIG. 7 is calculated, and the shopping time can be shortened. Thereby, the process of step S25 is completed, and the path change process proceeds from the process of step S25 to the process of step S28.

  In the process of step S <b> 26, the route search unit 21 connects to the store information DB 5 via the communication unit 24. The route search unit 21 sells the product at the lowest price at a store within a predetermined distance (for example, 15 km) or a predetermined time (for example, 20 minutes) from the user's home or the arrival time. The store is searched, and a route through which the purchased product can be purchased via the searched store and in the shopping list is searched. Specifically, when the products listed in the shopping list are three of cabbage, salmon, and beef and the store information DB 5 has the form shown in FIG. 3, the cabbage is handled at the A store and the C store. However, the route search unit 21 selects the store A with a lower price. Similarly, the route search unit 21 selects the store B and the store C that have the lowest price. On the other hand, since beef can be purchased only at store C, route search unit 21 selects store C as a store from which beef is purchased. As a result, a route traveling in the order of A store → B store → C store → home as shown in FIG. 8 is calculated, and the cost of shopping can be reduced. Thereby, the process of step S26 is completed, and the path change process proceeds from the process of step S26 to the process of step S28.

  In the process of step S <b> 27, the route search unit 21 connects to the store information DB 5 via the communication unit 24. Then, the route search unit 21 searches for a store where the time service can be used at a store within a predetermined distance or a predetermined time within the distance or arrival time of the user from the user's home, and in a time zone in which the time service can be used. A route through which the product can be purchased via the store and on the shopping list is searched. Specifically, when the products listed in the shopping list are three of cabbage, salmon, and beef and the store information DB 5 has the form shown in FIG. 3, the cabbage is handled at the A store and the C store. The time service can be used at the C store and at a low price. However, since the cheaper time zone is 10:00 to 12:00, the route search unit 21 selects the store C for shopping in the morning and the cheaper A for shopping in the afternoon. Select a store. Similarly, salmon is handled at store B and store C, but the time service can be used at store C and at a low price. However, since the low price period is from 17:30 to 19:00, the route search unit 21 selects the C store for evening shopping, and the cheaper price for other time periods. Select store B. On the other hand, since beef can only be purchased at store C, route search unit 21 selects store C as a store from which beef is purchased. As a result, the route search unit 21 travels in the order of A store → C store → home as shown in FIG. 9A if it is a time zone in which it can go to the store C between 10:00 and 12:00. If the route is calculated and it is a time zone in which it is possible to go to store C from 17:30 to 19:00, a route traveling in the order of store B → C store → home as shown in FIG. It is possible to calculate a travel route that matches the service time zone. Thereby, the process of step S27 is completed, and the path change process proceeds from the process of step S27 to the process of step S28.

  In the process of step S28, the route search unit 21 determines whether or not frozen food is included in the products described in the shopping list. And as a result of discrimination | determination, when frozen food is not contained, the route search part 21 advances this route change process from the process of step S28 to the process of step S30. On the other hand, when frozen food is included, the route search unit 21 advances the route change process from the process of step S28 to the process of step S29.

  In the process of step S29, the route search unit 21 changes the searched route so that the store where the frozen food is purchased becomes a transit point just before returning home. Specifically, when the store A, the store B, and the store C are used as a stopover and frozen food is purchased at the store C, the route search unit 21 stores the store A → B as shown in FIG. A route that travels in the order of store → C store → home is created. When cabbage, frozen salmon, and beef are listed in the shopping list, there are two frozen foods, and cabbage other than frozen foods can be purchased at the C store. As shown in FIG. 10 (b), by calculating the route traveling in the order of C store → home, it is possible to minimize the time during which the frozen food is exposed to room temperature and prevent the frozen food from being thawed. Thereby, the process of step S29 is completed, and the path change process proceeds from the process of step S29 to the process of step S30.

  In the process of step S30, the route search unit 21 displays the calculated travel route on the display monitor 22, and starts to guide the user who drives the vehicle 3 to travel on the calculated travel route. Thereby, the process of this step S30 is completed, and a series of path change processes are completed.

  In this embodiment, the vehicle 3 has a function for searching for a shopping route. However, the present invention is not limited to this configuration, and the shopping list creation server 6 and the store information DB 5 are provided with this function. Also good. However, in this case, the calculated shopping route information is transmitted to the vehicle 3 together with the shopping list.

  As is apparent from the above description, according to the shopping route guidance system according to the first embodiment of the present invention, the list creation unit 52 has insufficient ingredients for cooking the menu selected by the user and its To create a shopping list in which information on the quantity and information on the name and location of the store selling the food are written, and the route search unit 21 refers to the created shopping list to purchase the food The optimal shopping route is calculated and the user is guided according to the calculated shopping route, so that the user can purchase the product described in the product list reliably and efficiently. Moreover, it is possible to prevent the foodstuff from being unnecessarily purchased even though the foodstuff is in the refrigerator 2.

  In addition, according to the shopping route guidance system according to the first embodiment of the present invention, the route search unit 21 purchases a shopping route with the shortest time required to purchase an article according to an instruction from the user. Since one of the shopping route with the lowest necessary cost and the shopping route that can be used by the store time service is calculated, it is possible to present a shopping route that matches the user's purpose.

  Furthermore, according to the shopping route guidance system according to the first embodiment of the present invention, when frozen food is included in the article to be purchased, the route search unit 21 is the last one that the store where the frozen food is purchased purchases the item. Since the shopping route is calculated so as to become a store, it is possible to prevent the frozen food from being thawed before returning home.

  In the first embodiment, the shopping list is created based on the stock ingredients in the refrigerator 2, but as shown in FIGS. 11 and 12, for example, a beer stocker, a light bulb socket, a wash basin, a sundries shelf, and toilet paper It is also possible to detect the inventory of goods in places other than the refrigerator 2, such as a holder, a TV stand (video tape storage), a laundry basket, etc., and create a shopping list in consideration of the detection results. In this case, specifically, as shown in the flowchart of FIG. 13, the shopping list creation server 6 checks the stock food in the refrigerator 2 (step S <b> 31), and then the detection result of the detection unit provided in each place. In accordance with the above, whether or not the stock of beer in the beer stocker is equal to or larger than a predetermined number (step S32), whether or not the bulb has run out (step S34), and whether or not the toothpaste on the washstand remains (step S36). ), Whether the shelves are in stock (step S38), whether toilet paper remains (step S40), whether there are unreturned rental videos (step S42), and washing in the laundry basket It is determined whether or not an object has accumulated (step S44). In this case, the stock of the product can be detected based on the availability of communication with the IC tag attached to the product. In addition, the bulb breakage can be detected by providing a shunt resistor in the bulb socket.

  Then, the shopping list creation server 6 creates a shopping list by determining whether or not there is a need to go through a liquor store, an electrical store, a drug store, a home center, a general store, a rental video store, and a cleaning store according to the determination result. Then, the route search unit 23 determines a shopping route as shown in FIGS. 14A and 14B, for example, according to the shopping list created by the shopping list creation server 6. In the example shown in FIG. 14 (a), the route search unit 23 is configured because the stock of beer in the beer stocker is a predetermined number or less, there is no toothpaste on the washstand, and no toilet paper remains. This shows a case where a shopping route is calculated through a liquor store, drug store, and general store. Further, in the example shown in FIG. 14B, there is a bulb break, an unreturned rental video, and the laundry is stored in the laundry basket. This shows the case where a shopping route is calculated that goes through an electrical shop, a rental video shop, and a cleaning shop.

  The shopping route guidance system according to the second embodiment of the present invention can be applied to a process for preventing forgetting to buy foods described in a shopping list. The configuration and operation of the shopping route guidance system according to the second embodiment of the present invention will be described below with reference to FIGS.
