  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In FIG. 1, an in-vehicle device 100 includes a processing unit 11 that includes a computer unit (including a CPU) and executes various processes according to a program. Connected to the processing unit 11 are an AV unit 17 that performs reproduction processing of various sound sources and video sources (for example, CD and DVD) and a navigation unit 18 that performs navigation processing such as vehicle route guidance. The processing unit 11 is connected to an output circuit 15 to which a speaker 16 is connected. Under the control of the processing unit 11, audio signals from the AV unit 17 and the navigation unit 18 are supplied to the speaker 16 via the output circuit 15, and audio based on the audio signals is output from the speaker 16. The processing unit 11 further includes a storage unit 14 (for example, a hard disk) that stores various information such as audio information and video information reproduced by the AV unit 17 and map information used for processing by the navigation unit 18. Drive) is connected. The in-vehicle device 100 is configured by an LCD panel, and is configured by a display unit 13 provided in, for example, an instrument panel in a passenger compartment, a touch panel provided integrally with the display unit 13 (LCD panel), and the like. And an operation unit 12. The processing unit 11 can execute various types of processing based on input information in accordance with operations on the operation unit 12 and can display information such as images obtained by the various types of processing on the display unit 13.

  Furthermore, the in-vehicle device 100 includes a short-distance communication unit 19 that transmits and receives information by short-range wireless communication (for example, Bluetooth (registered trademark)) with a mobile terminal 200 such as a smartphone that functions as a mobile phone, and a predetermined mobile communication. It has a mobile communication unit 20 that communicates information with an external device such as a server on the Internet via a network. The processing unit 11 has a voice recognition function for acquiring voice information representing the conversation content on the mobile terminal 200 (mobile phone) via the short-range communication unit 19 and recognizing the conversation content from the voice information. In addition, the processing unit 11 can acquire various information on the Internet received by the mobile communication unit 20.

  The storage unit 14 stores a temperature-affected product list as shown in FIG. This temperature-affected product list represents product information (for example, product name) that identifies a product that is determined to be easily affected by a high temperature environment. Further, in the temperature-effect product list, each product (product information) is associated with rank information determined based on the degree of sensitivity to high temperature environment. Specifically, each of “frozen food” and “ice cream” is associated with a ranking “1” that is most susceptible to the influence of a high temperature environment, “meat” and “fresh fish”. Is associated with a rank “2” that is less susceptible to a high temperature environment than the rank “1”. Similarly, the rank “3” is associated with each of “dairy products” and “processed meat”, the rank “4” for “fresh confectionery”, and the rank “5” for “fresh vegetables”. Each is associated.

  In addition, the order matched with the goods which are easily influenced by the high temperature environment can be determined arbitrarily.

  Note that in the above-described in-vehicle device 100, the navigation device according to the embodiment of the present invention is configured by each unit excluding the AV unit 17.

  When the operation unit 12 performs an input operation of a destination (for example, home) together with a predetermined operation related to the route search, the processing unit 11 executes a route search process according to the procedure shown in FIG.

  For example, a vehicle occupant (for example, a husband) uses the mobile terminal 200 to have a conversation with a person outside the vehicle (for example, a wife) about product purchases, drop-in facilities, and the like. At that time, in FIG. 2, the processing unit 11 takes in voice information representing the content of the conversation on the mobile terminal 200 via the short-range communication unit 19 that transmits and receives information with the mobile terminal 200 by short-range communication. Record in memory (S11). When the capturing of the speech information representing the conversation content is completed, the processing unit 11 analyzes the speech information recorded in the internal memory according to a predetermined algorithm, and identifies the product requested by the occupant to purchase from the speech information. The product information and the facility information for identifying the facility requested to stop by the occupant are extracted (S12: product information acquisition means (voice product information extraction means), facility information acquisition means).

  Next, the processing unit 11 transmits / receives information to / from a predetermined management system (database) on the Internet via the mobile communication unit 19. Then, the processing unit 11 purchases the product specified by the extracted product information within a predetermined range including the current position and the destination (for example, home) in the management system (database) on the Internet. Searchable facilities, and as a search result, acquire product purchase facility information specifying a facility that can purchase the product specified by the product information (S13: product purchase facility information acquisition means) ).

  The processing unit 11 selects the facility specified by the facility information acquired from the conversation content (see S12) and the product purchase facility specified by the product purchase facility information (see S13) from the current position to the destination (for example, (S14). The processing unit 11 applies a temperature-affected product list (FIG. 2) to the product to be purchased at the product purchase facility specified by the product purchase facility information, that is, the product specified by the product information extracted from the conversation content. It is determined whether any of the products listed in (see) is included (S15). If it is not included (NO in S15), the processing unit 11 uses the facility determined as the stop-off facility as a transit point, and the route from the current position to the destination, for example, a normal algorithm with time priority or distance priority. (S18: Normal route search process).

  On the other hand, the product to be purchased at the product purchase facility specified by the product purchase facility information includes any product (for example, ice cream) listed in the temperature-effect product list (see FIG. 2). In the case (YES in S15), the processing unit 11 acquires temperature environment information representing the temperature environment in the vehicle (S16: temperature environment information acquisition means).

  The temperature environment information can be obtained, for example, as follows.

  It is possible to generate temperature environment information (may be information representing the outside air temperature itself) based on the outside air temperature detected by an outside air temperature detector (not shown) provided in the vehicle. In addition, temperature environment information based on the temperature in the passenger compartment detected by a passenger compartment temperature detector (not shown) provided in the vehicle (may be information representing the temperature of the passenger compartment itself) can be generated. Further, for example, temperature environment information based on season information representing the current season obtained by sending / receiving information to / from a predetermined system on the Internet via the mobile communication unit 19 (may be information representing the season itself), or In addition, temperature environment information (may be information representing the date itself) based on calendar information representing the date can be generated.

  When the temperature environment information is acquired (S16), the processing unit 11 determines whether or not the acquired temperature environment information represents a temperature environment predetermined as a high temperature environment (S17). For example, when temperature environment information based on the outside air temperature is acquired (S16), it is determined whether or not the temperature environment information represents a temperature equal to or higher than a predetermined outside air temperature, and the temperature based on the temperature inside the vehicle interior When the environmental information is acquired, it is determined whether or not the temperature environmental information represents a temperature that is equal to or higher than a predetermined vehicle interior temperature. In addition, when temperature environment information based on the season is acquired, it is determined whether or not the temperature environment information represents a summer time predetermined as a high temperature environment. When the information is acquired, it is determined whether or not the temperature environment information represents a period from June to September that is predetermined as a high temperature environment.

  When the acquired temperature environment information represents a temperature environment predetermined as a high temperature environment (YES in S17), the processing unit 11 uses the facility determined as the stop-off facility (see S14) as a transit point, In accordance with an algorithm that takes into account a time-preferred or distance-preferred normal algorithm, and an algorithm that allows a product purchase facility that can purchase a product listed in the temperature-sensitive product list to pass through later than other facilities. Then, a route from the current position to the destination (for example, home) is searched (S19: product-considered route search process). In the product-considered route search process (S19), a plurality of products that can purchase any of the products listed in the temperature-sensitive product list are further purchased at the facility determined as the stop-off facility (see S14). When a facility is included, based on the ranking information associated with each product (product information) in the temperature affected product list, the ranking is high (the numerical value indicating the ranking is small), that is, it is affected by the high temperature environment. The higher the degree of ease, the more the facility where the product can be purchased, and the route is searched so as to go through later in time.

  In addition, even if any of the products listed in the temperature-effect product list (see FIG. 2) is included in the determined drop-off facility, the temperature set in advance as the temperature environment in which the acquired temperature environment information is high If the environment is not represented (NO in S17), specifically, if the outside air temperature does not reach the predetermined temperature, or if it is in the winter season, the processing unit 11 affects the temperature of the drop-in facility. The route from the current position to the destination in accordance with a normal time-priority or distance-priority algorithm as in the case where no merchandise purchase facility that can purchase the merchandise listed in the merchandise list is included (NO in S15). (S18: normal route search process).

  When the route from the current position through the facility determined as the stop-off facility to the destination is searched by the normal route search process (S18) or the product-considered route search process (S19), the processing unit 11 The route obtained by the search is set as a route to guide the vehicle, and the process related to the route search is ended. Thereafter, the processing unit 11 executes a process related to vehicle navigation so as to guide the vehicle along with the set route together with the navigation unit 18.

  For example, as shown in FIG. 4, a “supermarket” that purchases “ice cream”, a “library”, a “home center” that purchases “tools”, and a “bakery” that purchases “bread” serve as drop-in facilities. If determined, in the normal route search process (see S18 in FIG. 3) according to the time-priority or distance-priority algorithm, the route R (10) from the current position (START) to the “supermarket” where “ice cream” is purchased. ), Route R (20) from “supermarket” to “library”, route R (30) from “library” to “home center” where “tool” is purchased, “pan” where “bread” is purchased from “home center” The route R (40) to “ya” and the route R (50) from “bakery” to the destination (home: GOAL) are searched as routes to be guided. It is. In this case, under a high temperature environment, the “ice cream” purchased at the “supermarket” arrives at the destination (eg, home) after the vehicle passes through many remaining transit points (library, home center, bakery). There is a possibility of melting by the time.

  In such a case, in the above-described product-considering route search process (see S19 in FIG. 3), it is a facility where “ice cream” that is a product listed in the temperature-affected product list (see FIG. 2) can be purchased. The route search is performed so that the “supermarket” passes through the other facilities “library”, “home center”, and “bakery” in time. Specifically, as shown in FIG. 5, a route R (11) from the current position (START) to “bakery” where “bread” is purchased, and “home center” where “tool” is purchased from “bakery”. Route R (21) to "Home Center" to "Library" R (31), Route R (41) from "Library" to "Supermarket" to purchase "Ice Cream", and "Supermarket" A route R (51) to the destination (for example, home) is searched as a route to be guided. In this case, the time for the vehicle to travel on the remaining route R (51) from the “supermarket”, which is a facility where “ice cream” can be easily purchased, easily affected by the high temperature environment, is shorter. Even under a predetermined temperature environment as a high temperature environment, it is possible for the vehicle to arrive at the destination (for example, home) without melting the “ice cream” purchased at the “supermarket” Increases nature.

  Further, for example, as shown in FIG. 6, “Aquarium”, “Souvenir shop A” for purchasing “fresh fish”, “Souvenir shop B” for purchasing folk crafts, and “Dairy products” are purchased at a sightseeing spot. When the souvenir shop C ”is determined as a stop-in facility, in the normal route search process (see S18 in FIG. 3) simply according to the normal algorithm of time priority or distance priority, from the current position (START) to“ Aquarium ” Route R (12), Route R (22) from “Aquarium” to “Souvenir Store A” where “fresh fish” is purchased, and Route R from “Souvenir Store A” to “Souvenir Store B” where crafts are purchased (32), a route R (42) from “souvenir shop B” to “souvenir shop C” for purchasing “dairy products”, and a route R (52) from “souvenir shop C” to the destination (for example, hotel) ) Is searched as a route to be guided. In this case, especially under the high temperature environment, the “fresh fish” purchased at “souvenir shop A” passes through the remaining many transit points (souvenir shop B, souvenir shop C) and the destination (for example, hotel ) May be altered by the time you arrive.

  In such a case, in the above-described product-considering route search process (see S19 in FIG. 3), “souvenir shop A” is a facility where “fresh fish” listed in the temperature-affected product list (see FIG. 2) can be purchased. "Souvenir shop C", which is a facility that can purchase "dairy products" listed in the temperature-sensitive product list, is a facility that purchases "aquarium" and "folkcraft", which are other facilities. The route is searched so as to pass after the souvenir shop B ”. Furthermore, “fresh fish” to be purchased at “souvenir shop A” from the order (3: refer to FIG. 2) indicating the degree of influence of the high temperature environment on “dairy products” to be purchased at “souvenir shop C”. The order indicating the degree of susceptibility to the influence of the high temperature environment (2: see FIG. 2) is higher, so the route so that “souvenir shop A” passes through “souvenir shop C” later in time. Search is made. As a result, as shown in FIG. 7, a route R (12) from the current position (START) to “Aquarium”, and a route R (32) from “Aquarium” to “Souvenir Shop B” where “Crafts” are purchased. , Route R (33) from “souvenir shop B” to “souvenir shop C” for purchasing “dairy products”, route R (43) from “souvenir shop C” to “souvenir shop A” for purchasing “fresh fish” ), And a route R (53) from “souvenir shop A” to a destination (for example, a hotel) is searched as a route to be guided.

  In this case, the remaining route R (43) + R (53) from the “souvenir shop C” where the “dairy product” that is easily affected by the high temperature environment can be purchased to the destination (for example, a hotel) and the high temperature environment The time that the vehicle travels on each of the remaining routes R (53) from “souvenir shop A” where the “fresh fish” that is susceptible to purchase to the destination (for example, a hotel) is the other facility is “ The remaining route R (23) + R (33) + R (43) + R (53) from “Aquarium” to the destination and the remaining route R (33) + R (43) + R (from “souvenir shop B” to the destination 53) is shorter than the time during which the vehicle travels. Furthermore, the time for the vehicle to travel on the remaining route R (53) from “souvenir shop A” where “fresh fish” that can be easily affected by a higher temperature environment than “dairy products” to the destination is “milk” The time required for the vehicle to travel the remaining route R (43) + R (53) from “souvenir shop C” where the product can be purchased to the destination is shorter. Therefore, even under a temperature environment predetermined as a high temperature environment, the “dairy products” purchased at “souvenir shop C” and “fresh fish” purchased at “souvenir shop A” do not change, The possibility that the vehicle can arrive at the destination (eg, a hotel) is increased.

  According to the navigation apparatus described above, facilities (supermarkets and souvenir shops A) where products (ice cream, fresh fish, etc.) that are easily affected by the high temperature environment can be purchased under a temperature environment predetermined as the high temperature environment. ) To the destination, the route is searched so that the time required for the vehicle to travel on the remaining route from the other facilities to the destination is shorter than the time required for the vehicle to travel. It is possible to search for an appropriate route through which various products can be purchased in consideration of products that are easily affected by a high temperature environment.

  In the navigation device described above, the product information representing the product and the facility information representing the facility are extracted from the conversation content on the mobile terminal 200, but the present invention is not limited to this. For example, the product information and the facility information may be provided directly to the processing unit 11 by an operation on the operation unit 12, or may be taken into the processing unit 11 by voice input and voice recognition techniques. . In particular, as shown in FIGS. 6 and 7, in the case of searching for a route through each facility in a sightseeing spot, product information (souvenir products) and facility information (sightseeing spots, souvenir shops, etc.) It is preferable that the processing unit 11 is made to take in by operation or a technique of voice input and voice recognition.

  In addition, facilities that can purchase products specified by product information were acquired from a management system (database) on the Internet, but by limiting to limited areas such as sightseeing spots and homes. A database for managing such facilities can also be held in the storage unit 14 of the in-vehicle device 100.
