[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a navigation control device and a navigation method according to embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments.

[0011] [Embodiment] <Navigation system> 1 is a block diagram showing an outline of a navigation system including a navigation control device according to a first embodiment. In a vehicle capable of switching between automatic driving and manual driving, the navigation system 1 supports meals during automatic driving according to the automatic driving time. More specifically, in a vehicle capable of switching between automatic driving and manual driving by the driver's driving operation, the navigation system 1 searches for meal menu candidates during automatic driving according to the automatic driving time and presents them to the passengers.

[0012] The vehicle is driven autonomously, for example, on roads and areas where autonomous driving is possible, etc. The vehicle is manually driven, for example, on roads and areas where autonomous driving is not possible, other than those where autonomous driving is possible.

[0013] The navigation system 1 may be mounted on a vehicle or may be portable and carried into the vehicle. The navigation system 1 may be configured as a portable terminal, a device installed in the vehicle, or a combination of several devices. The navigation system 1 includes a GNSS (Global Navigation Satellite System) receiving unit 11, a map information storage unit 12, an operation unit 13, a restaurant information storage unit 14, a display unit 19, and a navigation control device 20.

[0014] The GNSS receiving unit 11 is configured with a GNSS receiver that receives GNSS signals from GNSS satellites, etc. The GNSS receiving unit 11 outputs the received GNSS signals to a position information acquiring unit 21 of the navigation control device 20.

[0015] The map information storage unit 12 stores map information. The map information storage unit 12 outputs the stored map information to a map information acquisition unit 22 of the navigation control device 20. The map information storage unit 12 may be a storage device such as an external server that acquires map information via a communication function.

[0016] The map information is, for example, a road map including intersections. The map information includes, for example, information indicating speed limits from which a planned driving time, which is the time required to drive each section of each road, can be calculated. The map information may include traffic information such as congestion information and regulation information in order to more accurately calculate the planned driving time for each section of each road. The map information includes, for example, information that can distinguish whether to perform automatic driving or manual driving, such as a section of a road where automatic driving is possible or a section of a road where automatic driving is restricted.

[0017] The operation unit 13 can accept various operations for the navigation system 1. The operation unit 13 is configured, for example, by a physical operation means for the navigation system 1, or a touch panel arranged on the display unit 19. The operation unit 13 outputs operation information to an operation acceptance unit 24 of the navigation control device 20.

[0018] For example, the operation unit 13 can accept an operation to input a destination. For example, the operation unit 13 can accept an operation to select a destination. For example, the operation unit 13 can accept an operation to start route guidance. For example, the operation unit 13 can accept an operation to select a meal menu candidate. For example, the operation unit 13 can accept a meal request operation to execute a meal menu search process.

[0019] The meal request operation is an operation for a passenger to search for a meal menu at any timing, such as while traveling to a destination. In the meal request operation, for example, it may be possible to input meal conditions such as a planned meal start time, which is the time when the passenger wants to eat a meal, or a planned meal start location, which is the approximate place where the passenger wants to eat a meal. Information indicating the meal conditions input in the meal request operation is added to the meal request operation information.

[0020] The restaurant information storage unit 14 stores restaurant information. The restaurant information storage unit 14 outputs the stored restaurant information to the meal menu search unit 34 of the navigation control device 20. The restaurant information storage unit 14 may be a storage device such as an external server that acquires restaurant information via a communication function.

[0021] The restaurant information is information indicating restaurants where a meal menu can be purchased. For example, the restaurant information is information indicating restaurants where a meal menu can be purchased for takeout, or restaurants where a meal menu can be delivered to a vehicle that is traveling autonomously by a delivery mobile object such as an autonomous driving vehicle or a drone. The restaurant information includes information indicating at least one of the restaurant name and location, business hours, delivery area, food genre, ordering destination (contact information), meal menu, price of the meal menu, and time required to eat the meal menu.

[0022] The display unit 19 is, for example, a display device specific to the navigation system 1, or a display device shared with other systems including a car audio system. The display unit 19 is, for example, a display including a liquid crystal display (LCD) or an organic EL (Electro-Luminescence) display. In this embodiment, the display unit 19 is a touch panel display. In other words, the display unit 19 functions as the operation unit 13 and is capable of inputting various operations. When the navigation system 1 is installed in a vehicle, the display unit 19 is disposed in front of the driver of the vehicle on a dashboard, an instrument panel, a center console, or the like. The display unit 19 displays an image of a destination setting screen based on a video signal output from a display control unit 39 of the navigation control device 20. The display unit 19 displays an image of a meal menu candidate based on a video signal output from the display control unit 39 of the navigation control device 20. The display unit 19 displays an image of a route guidance based on a video signal output from the display control unit 39 of the navigation control device 20.

[0023] <Navigation control device> The navigation control device 20 may be implemented as one of the functions of a navigation system for a vehicle. In this embodiment, the navigation control device 20 is implemented as a function of a navigation system mounted on a vehicle. The navigation control device 20 is, for example, an arithmetic processing device configured with a CPU (Central Processing Unit) or the like. The navigation control device 20 executes instructions included in a program stored in a storage unit (not shown). In a vehicle capable of switching between automatic driving and manual driving, the navigation control device 20 controls the vehicle to search for meal menu candidates during automatic driving according to the automatic driving time and present them to the passenger. The navigation control device 20 has a position information acquisition unit 21, a map information acquisition unit 22, an operation acceptance unit 24, a route search unit 31, a route guidance unit 32, a meal menu search unit 34, a determination unit 35, and a display control unit 39.

[0024] The position information acquisition unit 21 acquires current position information indicating the current position of the vehicle. In this embodiment, the position information acquisition unit 21 acquires the current position information of the vehicle based on the GNSS signal acquired by the GNSS receiver 11.

[0025] The map information acquisition unit 22 acquires map information from the map information storage unit 12. More specifically, the map information acquisition unit 22 acquires map information relating to a route from the current position of the vehicle to the destination from the map information storage unit 12, based on the current position of the vehicle and the position information of the destination acquired by the position information acquisition unit 21.

[0026] The operation reception unit 24 acquires operation information of the operation accepted by the operation unit 13. For example, the operation reception unit 24 acquires destination input operation information indicating an input operation of a destination, and outputs a control signal. For example, the operation reception unit 24 acquires selection operation information indicating an operation of selecting a candidate destination, and outputs a control signal. For example, the operation reception unit 24 acquires selection operation information indicating an operation of selecting a candidate of a searched route, and outputs a control signal. For example, the operation reception unit 24 acquires selection operation information indicating an operation of selecting a searched meal menu candidate, and outputs a control signal. For example, the operation reception unit 24 acquires meal request operation information indicating a meal request operation, and outputs a control signal. For example, the operation reception unit 24 acquires guidance start operation information indicating an operation of starting route guidance, and outputs a control signal.

[0027] The route search unit 31 searches for a route from the current position of the vehicle to the destination. In this embodiment, the route search unit 31 searches for a route from the current position of the vehicle to the destination, including an autonomous driving section. The route search unit 31 presents the searched route to a passenger in the vehicle. The method of searching for a route is not limited and any known route search method can be used.

[0028] The route search unit 31 sets manual driving sections and automatic driving sections based on map information. For example, the route search unit 31 sets a section of a route that the map information indicates is a section of a road where automatic driving is possible as an automatic driving section, and sets a section that the map information indicates is a section of a road where automatic driving is restricted as a manual driving section. The automatic driving section and the manual driving section may be set by a setting operation by the passenger.

[0029] The route search unit 31 adds information to the route information of the searched route for distinguishing between manual driving sections where manual driving is performed and automatic driving sections where automatic driving is performed. More specifically, the route search unit 31 adds information indicating that the roads or areas of the searched route where automatic driving is possible are automatic driving sections. The route search unit 31 adds information indicating that the roads or areas of the searched route are manual driving sections to sections other than the automatic driving sections.

[0030] The route search unit 31 adds information indicating the planned driving time for each of the manual driving sections and the automatic driving sections to the route information, based on the information indicating the speed limit and traffic information included in the map information.

[0031] When the operation reception unit 24 receives an operation to select a meal menu candidate, the route search unit 31 adds information indicating the location of a restaurant that provides the selected meal menu to the route information.

[0032] When the determination unit 35 determines that the time required for a meal is longer than the planned driving time, the route search unit 31 may re-search for a route in the autonomous driving section such that the planned driving time is longer than the time required for a meal. The route search unit 31 may re-search for a route in the autonomous driving section such that a meal can be eaten within the autonomous driving time, according to the time required for a meal of the meal menu selected by the passenger. For example, the route search unit 31 re-searches for a route in the autonomous driving section that takes a detour so that the planned driving time is longer than the time required for a meal.

[0033] The time required for a meal may be the time it takes to eat a meal, or the time it takes to eat a meal plus the time it takes to clean up after the meal.

[0034] The route search unit 31 calculates the planned driving time for driving the remaining autonomous driving section from the planned meal start position or the planned meal start time based on the meal conditions input during the meal request operation. More specifically, when the planned meal start position included in the meal conditions is within the autonomous driving section, the route search unit 31 calculates the planned driving time for driving the remaining autonomous driving section starting from the planned meal start position. When the planned meal start time included in the meal conditions is within the planned driving time for driving the autonomous driving section, the route search unit 31 calculates the planned driving time for driving the remaining autonomous driving section starting from the planned meal start time.

[0035] The route guidance unit 32 provides route guidance from the current position of the vehicle to the destination. More specifically, the route guidance unit 32 provides route guidance along the searched route. The method of providing route guidance can be any known route guidance method and is not limited to this method.

[0036] The meal menu search unit 34 searches for meal menu candidates that can be eaten within the planned driving time, which is the planned time for driving the automatic driving section of the route searched by the route search unit 31.

[0037] More specifically, based on the route information and the restaurant information stored in the restaurant information storage unit 14, the meal menu search unit 34 searches for candidate meal menus that can be provided by restaurants located along the route and that correspond to the planned driving time for driving through the autonomous driving section, in other words, that can be completed within the planned driving time.

[0038] When the planned driving time is short, the meal menu search unit 34 searches for a meal menu that can be easily finished as a candidate. For example, when the planned driving time is short, such as 30 minutes or less, the meal menu search unit 34 searches for fast food that can be easily eaten or food and drink purchased at a convenience store or the like as one of the meal menu candidates.

[0039] For example, when the planned driving time is about 60 minutes or more and less than 120 minutes, the meal menu search unit 34 searches for a lunch box or a set meal as one of the meal menu candidates.

[0040] When the planned driving time is long, the meal menu search unit 34 searches for meal menus that require a long time to eat as candidates. For example, when the planned driving time is long, such as 120 minutes or more, the meal menu search unit 34 searches for course meals that require a long time to eat as one of the meal menu candidates.

[0041] For example, the meal menu search unit 34 may search for local menus as one of the meal menu candidates according to the locations around the route. For example, if the route passes near the sea, the meal menu search unit 34 may search for a meal menu of a seafood restaurant as one of the candidates.

[0042] The meal menu search unit 34 may search for one of the meal menu candidates according to the purpose of driving, in addition to the route information and the restaurant information.

[0043] The meal menu search unit 34 may, for example, infer the purpose of driving from the destination and search for meal menu candidates. For example, when the destination is a corporate office or factory and the driving purpose is inferred to be business, the meal menu search unit 34 may search for lunch boxes or set meals as one of the meal menu candidates. For example, when the destination is a leisure facility and the driving purpose is inferred to be leisure, the meal menu search unit 34 may search for so-called local gourmet food such as specialty dishes around the route or destination as one of the meal menu candidates.

[0044] The meal menu search unit 34 may, for example, infer the purpose of driving from the attributes of the passenger and search for meal menu candidates. For example, if the passenger is a family member, the meal menu search unit 34 may infer the purpose of driving is private and search for local menus as one of the meal menu candidates. For example, if the passenger is a colleague of a company, the meal menu search unit 34 may infer the purpose of driving is business and search for set meals as one of the meal menu candidates.

[0045] The attributes of the passengers can be acquired, for example, by performing image analysis on images from an in-vehicle camera (not shown).

[0046] The meal menu search unit 34 may search for meal menu candidates according to the planned driving time for driving the autonomous driving section, starting from the planned meal start position included in the meal conditions, based on the route information, restaurant information, and further the meal conditions input during the meal request operation. If the planned meal start position is outside the autonomous driving section, for example, the closest autonomous driving section to the planned meal start position may be used.

[0047] The meal menu search unit 34 may search for meal menu candidates according to the planned driving time for driving the autonomous driving section, calculated from the planned meal start time included in the meal conditions, based on the route information, restaurant information, and further the meal conditions input during the meal request operation. If the driving position corresponding to the planned meal start time is outside the autonomous driving section, for example, the closest autonomous driving section to the driving position may be used.

[0048] The determination unit 35 determines whether or not it is possible to eat within the autonomous driving time. More specifically, the determination unit 35 compares the planned driving time for driving the autonomous driving section with the meal time required for a meal of the selected meal menu, and determines whether or not the meal time is longer than the planned driving time.

[0049] The display control unit 39 displays route candidates searched by the route search unit 31 on the display unit 19. The display control unit 39 displays the route candidates, for example, as a list or by superimposing them on a map image. The passenger can select a route from the route candidates displayed on the display unit 19.

[0050] The display control unit 39 displays the route guided by the route guidance unit 32. The display control unit 39 causes the display unit 19 to display an image of route guidance along the route guided by the route guidance unit 32.

[0051] The display control unit 39 controls the display unit 19 to display the meal menu candidates searched by the meal menu search unit 34. The display control unit 39, for example, causes the meal menu candidates to be displayed in a list. The passenger can select a meal menu from the meal menu candidates displayed on the display unit 19.

[0052] <Processing in the navigation control device> Next, information processing in the navigation system 1 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a flowchart showing the flow of processing in the navigation control device according to the first embodiment. Fig. 3 is a flowchart showing another example of the flow of processing in the navigation control device according to the embodiment.

[0053] 2, a case where the process of the flowchart shown in FIG. 2 is executed when the vehicle engine is started or when the navigation system 1 is activated will be described.

[0054] The navigation control device 20 searches for a route including an autonomous driving section (step S101). More specifically, the navigation control device 20 uses the route search unit 31 to search for a route including an autonomous driving section from the current position of the vehicle to the destination. The navigation control device 20 sets a manual driving section and an autonomous driving section based on map information using the route search unit 31. The navigation control device 20 proceeds to step S102.

[0055] The navigation control device 20 searches for meal menu candidates (step S102). More specifically, the navigation control device 20 searches for meal menus that are located along the route and that can be completed within the planned driving time for driving the autonomous driving section, based on the route information searched by the meal menu search unit 34 and the restaurant information stored in the restaurant information storage unit 14. The navigation control device 20 proceeds to step S103.

[0056] The navigation control device 20 displays the meal menu candidates (step S103). More specifically, the navigation control device 20 causes the display control unit 39 to display the meal menu candidates searched for by the meal menu search unit 34 on the display unit 19. The navigation control device 20 proceeds to step S104.

[0057] In step S103, when the candidate meal menus are displayed on the display unit 19, the passenger performs a selection operation to select the meal menu that he or she will actually eat from the candidate meal menus. The navigation control device 20 may enable the passenger to order the selected meal menu from a restaurant via a communication unit (not shown) or a communication unit of an electronic device carried by the passenger that is linked to the navigation system 1.

[0058] The navigation control device 20 judges whether a selection operation of a meal menu candidate has been detected (step S104). More specifically, if the operation reception unit 24 acquires operation information indicating that a meal menu candidate selection operation has been performed (Yes in step S104), the navigation control device 20 proceeds to step S105. If the operation reception unit 24 does not acquire operation information indicating that a meal menu candidate selection operation has been performed (No in step S104), the navigation control device 20 executes the process of step S101 again.

[0059] When operation information indicating that a meal menu candidate selection operation has been performed is acquired (Yes in step S104), the navigation control device 20 judges whether or not it is possible to eat within the autonomous driving time (step S105). More specifically, the navigation control device 20 uses the judgment unit 35 to compare the planned driving time for driving the autonomous driving section with the meal time required for a meal of the selected meal menu, and judges whether or not the meal time is longer than the planned driving time. When the navigation control device 20 judges that it is possible to eat within the autonomous driving time (Yes in step S105), it proceeds to step S107. When the navigation control device 20 does not judge that it is possible to eat within the autonomous driving time (No in step S105), it proceeds to step S106.

[0060] If it is not determined that a meal is possible within the autonomous driving time (No in step S105), the navigation control device 20 re-searches for a route in the autonomous driving section that matches the required meal time (step S106). More specifically, the navigation control device 20 causes the route search unit 31 to re-search for a route including the autonomous driving section from the current position of the vehicle to the destination, according to the required meal time for the selected meal menu, so that a meal is possible within the autonomous driving time. The navigation control device 20 proceeds to step S107.

[0061] The navigation control device 20 provides route guidance (step S107). More specifically, the navigation control device 20 provides route guidance using the route guidance unit 32. The navigation control device 20 ends the processing of this flowchart.

[0062] After executing step S107, the vehicle drives autonomously in the autonomous driving section along the route, stops at a restaurant that provides the selected meal menu (hereinafter referred to as the "selected restaurant"), and takes the meal menu home with it. Alternatively, the vehicle may drive autonomously in the autonomous driving section along the route, meet up with a delivery vehicle of the selected restaurant, and receive the meal menu.

[0063] In order to accurately determine whether or not it is possible to eat within the autonomous driving time, the processes from step S105 onward may be performed at a predetermined time interval after step S107 is performed. For example, if the vehicle speed indicated by the vehicle information acquired by a vehicle information acquisition unit (not shown) is faster than initially planned, the process of step S106 is performed again to re-search for a route in the autonomous driving section that takes a longer route so as to extend the autonomous driving time. For example, if the image of the in-vehicle camera (not shown) is analyzed and it is recognized that eating is delayed, the process of step S106 is performed again to re-search for a route in the autonomous driving section that takes a longer route so as to extend the autonomous driving time.

[0064] 3, a case will be described in which the process of the flowchart shown in FIG. 3 is executed when a meal request operation is received from a passenger before or during travel to a destination.

[0065] The processes in steps S113 to S118 shown in FIG. 3 are similar to those in steps S102 to S107 shown in FIG.

[0066] The navigation control device 20 determines whether a meal request operation has been detected (step S111). More specifically, if the operation reception unit 24 has acquired operation information indicating that a meal request operation has been performed (Yes in step S111), the navigation control device 20 proceeds to step S112. If the operation reception unit 24 has not acquired operation information indicating that a meal request operation has been performed (No in step S111), the navigation control device 20 executes the process of step S111 again.

[0067] The navigation control device 20 calculates the planned driving time for traveling the remaining automated driving section from the planned meal start position or the planned meal start time (step S112). More specifically, if the planned meal start position is within the automated driving section or the planned meal start time is included in the planned driving time for traveling the automated driving section, the navigation control device 20 calculates the planned driving time for traveling the remaining automated driving section from the planned meal start position or the planned meal start time by the route search unit 31. The navigation control device 20 proceeds to step S113.

[0068] In this way, even if a meal is started during an autonomous driving section, it is possible to present passengers with appropriate meal menu options based on the remaining autonomous driving time.

[0069] As described above, in this embodiment, it is possible to search for and display candidates for meal menus that can be eaten within the planned driving time for driving the autonomous driving section of the route. According to this embodiment, it is possible to suggest a meal menu that can be finished within the planned driving time for the autonomous driving section. This embodiment can appropriately suggest a meal menu according to the autonomous driving time.

[0070] In this embodiment, it is possible to search for meal menu candidates that can be eaten within the planned driving time for driving the autonomous driving section, starting from the planned meal start position indicated by the meal request operation information, or within the planned driving time for driving the autonomous driving section, calculated from the planned meal start time indicated by the meal request operation information. According to this embodiment, it is possible to propose a meal menu that matches the passenger's desires and corresponds to the planned driving time for driving the remaining autonomous driving section.

[0071] In this embodiment, when it is determined that the time required for a meal is longer than the planned driving time in the autonomous driving section, a route can be searched for that will make the planned driving time longer than the time required for a meal. According to this embodiment, it is possible to re-search for a route in the autonomous driving section so that the meal menu can be finished while driving in the autonomous driving section.

[0072] In this embodiment, it is possible to search for meal menu candidates according to the purpose of the trip, and thus the meal menu can be more appropriately suggested.

[0073] In this embodiment, in addition to the time to eat, the time to clean up after a meal is taken into consideration, and it is possible to suggest candidate meal menus that can be eaten within the planned driving time for traveling through an autonomous driving section.

[0074] Each component of the illustrated navigation system is a functional concept, and does not necessarily have to be physically configured as illustrated. In other words, the specific form of each device is not limited to that shown in the figure, and all or part of the device may be functionally or physically distributed or integrated in any unit depending on the processing load and usage status of each device.

[0075] The configuration of the navigation system is realized, for example, as software, by a program loaded into a memory. In the above embodiment, the configuration has been described as functional blocks realized by the cooperation of these hardware and software. In other words, these functional blocks can be realized in various forms by only hardware, only software, or a combination of both.

[0076] The components described above include those that a person skilled in the art can easily imagine and those that are substantially the same. Furthermore, the configurations described above can be appropriately combined. Furthermore, various omissions, substitutions, or modifications of the configurations are possible without departing from the scope of the present invention.

[0077] The navigation control device 20 may include a meal menu order processing unit (not shown) that orders a meal menu from a restaurant.

[0078] The meal menu order processing unit processes orders for meal menus from restaurants via a communication unit (not shown). When receiving a meal from a restaurant's delivery vehicle, the meal menu order processing unit determines a pick-up location within the autonomous driving section. When receiving a meal from a restaurant's delivery vehicle, the meal menu order processing unit may determine a collection location within the autonomous driving section for tableware provided when the meal menu is provided, leftover food, etc. This allows passengers to more easily receive their meals and have tableware, leftover food, etc. collected.

[0079] In addition, if the time from the current autonomous driving section to the next autonomous driving section is short or within a predetermined time, the cumulative time may be defined as the planned driving time. The predetermined time is, for example, two minutes. [Explanation of symbols]
