In addition, the format, content, and the like of each information described in this embodiment are merely examples, and the format, content, and the like are not limited as long as the meaning of each information can be indicated.

(Embodiment 1)
In the present embodiment, a navigation system 1 including a navigation device 11 and one or more types of display devices 12 will be described. The navigation device 11 and the display device 12 output guidance related information in different output modes.

  The guidance related information is information related to guidance of a route to a destination. The route guidance to the destination may be, for example, guidance during travel. The guidance related information includes, for example, a map corresponding to the current position, a route corresponding to the current position, a distance to the nearest intersection on the route, a traveling direction at the nearest intersection on the route, and a distance to the destination. Information indicating the scheduled time of arrival at the destination, the scheduled time of arrival at the destination, the elapsed time since departure, and the like. The map corresponding to the current position is specifically a map centered on the current position. Further, the current position may not be the center of the map. The route corresponding to the current position is specifically a route that has not traveled among the searched routes. In other words, the route corresponding to the current position is a route to the destination including at least the current position. In addition, the intersection is preferably an intersection that changes a traveling direction (path), that is, an intersection scheduled to turn right or left.

  The guidance related information can be classified by, for example, the level of detail of the content indicated by the guidance related information, the type of guidance content indicated by the guidance related information, the type of data format of the guidance related information, and the like. Hereinafter, the content type is appropriately referred to as a content type. In addition, hereinafter, the type of data format is appropriately referred to as a format type.

  It can be said that the level of detail is the degree of information content of the guidance related information. Further, the number of detail levels (sections) does not matter. In general, the level of detail is preferably 2 or more. The level of detail includes, for example, a large amount of information, a medium amount of information, and a small amount of information. The content type includes, for example, a map corresponding to the current position, a route corresponding to the current position, a distance to the nearest intersection on the route, a traveling direction at the nearest intersection on the route, and the like. The format type is, for example, an image, a character, a numerical value, a sound, or the like. Further, the information indicating the degree of detail is hereinafter referred to as detail level information as appropriate. Further, the information indicating the content type is hereinafter referred to as content type information as appropriate. Further, the information indicating the format type is hereinafter referred to as format type information as appropriate.

  In addition, the guidance related information output from the navigation device 11 and the guidance related information output from the display device 12 usually have different output modes. Different output modes include, for example, different levels of detail, different content types, different format types, and the like. In addition, different output modes may include, for example, different output destinations of guidance related information. Further, the difference in the output mode may include, for example, that the guidance related information is output to any one of two or more output destinations. “Guidance-related information is output to any one of the two or more output destinations” means, for example, that one of the navigation device 11 and the display device 12 is output and the other is not output. is there. In addition, when the degree of detail is different or the type is different, the content type of the guidance related information is preferably the same.

  For example, when guidance related information is output in the navigation device 11, it is preferable that the guidance related information has a high level of detail. For example, when guidance related information is output in the display apparatus 12, it is suitable for the said guidance relevant information that a detail level is low, for example.

  In the navigation device 11, guidance related information is output by an output unit 118 described later. In the display device 12, guidance related information is output by a display output unit 122 described later. In addition, the output destination of the guidance related information can be usually switched between one or both of the navigation device 11 and the display device 12.

The display device 12 includes a display reception unit 121 and a display output unit 122.

  Map information is stored in the map information storage unit 111 constituting the navigation device 11. Map information is information about a map. Moreover, the kind of map shown by map information, the data format of map information, etc. are not ask | required. The types of the maps are, for example, topographic maps, topographic maps, geological maps, land use maps, housing maps, route maps, road maps, guide maps, aerial photographs, satellite photographs, and the like. The data format is, for example, raster data, vector data, KIWI format, or the like.

  In addition, the map information usually has one or more road information indicating roads. The road information includes, for example, information indicating the name of the road, the type of road, the positions of both ends of the road, and the like. The road information includes, for example, a road score and information for identifying the road. The score is usually a cost used for route search. The road information may be associated with information for identifying the road information.

  Further, the map information may have, for example, one or more pieces of point information indicating points on the map. The point information is information having at least position information indicating the position of the point. The position is usually longitude and latitude. The position may be coordinates on a map, for example. Further, the position may include, for example, a height (altitude). The point information may include information indicating the name of the point, the type of the point, and the like. The kind of the said point is not ask | required. The type of the point is, for example, an intersection, a break point, a tourist attraction, a station, a restaurant, various stores, and the like. The break point is, for example, a gas station or a so-called convenience store. Further, the “point” may be, for example, an end point of a road.

  The output destination information storage unit 112 stores one or more pieces of output destination information. The output destination information is information indicating one or more output destinations of guidance related information. The output destination is one or both of the navigation device 11 and the display device 12. The output destination information is usually identification information for identifying the navigation device 11 and the display device 12. The identification information is, for example, an ID, a name, an IP address, a MAC address, or the like.

  Further, the output destination information may indicate one output destination for one output destination information, for example. Further, the output destination information may indicate two or more output destinations for one piece of output destination information, for example. The output destination information is, for example, “main body”, “room mirror”, “main body & room mirror”, and the like.

  The output destination information may be information indicating a so-called mode, for example. The said mode is a mode regarding the output mode of guidance related information, for example. In addition, the output mode includes, for example, that the guidance related information is detailed or the guidance related information is simple (simplified). The output destination information indicating the mode is, for example, “detail display mode”, “simple display mode”, “detail & simple display mode”, and the like.

  The output destination information may be associated with, for example, detail level information or format type information.

  The current position information acquisition unit 113 acquires current position information. The current position information is information indicating the current position. The current position information is position information indicating the current position. Further, the current position information acquisition unit 113 normally acquires current position information periodically. The current position information acquisition unit 113 normally acquires current position information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a mobile communication base station. In this case, the current position information acquisition unit 113 may have these devices or may be realized by these devices. Further, the processing procedure of the current position information acquisition unit 113 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The output destination information acquisition unit 114 acquires output destination information according to the operation of the navigation device 11. The operation includes, for example, executing functions such as a television function, an audio function, a video function, and a car navigation function. The output destination information is output destination information stored in the output destination information storage unit 112.

  For example, when the navigation device 11 starts a predetermined operation, the output destination information acquisition unit 114 acquires output destination information indicating that the output destination of guidance related information is the display device 12. In this case, the output destination information acquisition unit 114 holds, in advance, one or more operation conditions that are conditions related to the operation of the navigation device 11, for example. The operating conditions are, for example, that the navigation device 11 has started to execute a television function, has started to execute an audio function, and has started to execute a video function. Then, the output destination information acquisition unit 114 acquires operation information that is information indicating the operation of the navigation device 11. The operation information is stored in a predetermined storage area, for example. Then, the output destination information acquisition unit 114 determines whether the acquired operation information satisfies one of the one or more operation conditions that are held. And when satisfy | filling, the output destination information acquisition part 114 acquires the output destination information which shows that an output destination is the display apparatus 12 from the output destination information storage part 112. FIG.

  Moreover, the output destination information acquisition part 114 may acquire the output destination information which shows the output destination according to operation | movement of the navigation apparatus 11, for example. In this case, the output destination information acquisition unit 114 holds, in advance, one or more pieces of output destination management information, which is information in which operation conditions and output destination information are associated, for example. The output destination management information may be stored in the output destination information storage unit 112, for example. Then, the output destination information acquisition unit 114 acquires operation information. Then, the output destination information acquisition unit 114 determines whether the acquired operation information satisfies any one or more operation conditions. Then, the output destination information acquisition unit 114 acquires output destination information corresponding to the operation condition that the operation information satisfies.

  Note that when the output destination information is associated with information such as the detail level information and the format type information, the output destination information acquisition unit 114 usually acquires the output destination information together with the corresponding information.

  The accepting unit 115 accepts instructions and information. “Accept” refers to acquisition of information input from an input device such as a touch panel or a keyboard, acquisition of information stored in a recording medium such as an optical disk, magnetic disk, or semiconductor memory, and transmission via a wired or wireless communication line. It is a concept that includes receiving information that has been received.

  The instruction received by the receiving unit 115 is, for example, a destination selection instruction that is an instruction for selecting a destination, an output destination selection instruction that is an instruction for selecting an output destination, or the like. It can be said that the destination selection instruction is an instruction to select destination information. It can also be said that the output destination selection instruction is an instruction to select output destination information. Here, the destination information is information indicating the destination. The destination information is point information indicating the destination. Further, the spot information selected by the destination selection instruction is usually spot information that the map information stored in the map information storage unit 111 has. Further, the output destination information selected by the output destination selection instruction is usually the output destination information stored in the output destination information storage unit 112.

  The information received by the receiving unit 115 is, for example, destination information, output destination information, and the like. For example, the reception unit 115 receives destination information selected by a destination selection instruction received by the reception unit 115. In addition, the reception unit 115 receives, for example, output destination information selected by an output destination selection instruction received by itself. In addition, the reception unit 115 receives, for example, the output destination information acquired by the output destination information acquisition unit 114.

  In addition, the reception unit 115 may receive the output destination information at a predetermined timing, for example. The predetermined timing is, for example, after the navigation apparatus 11 is turned on or after the route information is acquired by the route search unit 116 described later. In this case, the reception unit 115 normally receives the output destination information selected by the output destination selection instruction.

  The accepting unit 115 may accept an instruction such as power ON or power OFF. When the reception unit 115 receives these instructions, the navigation device 11 normally performs processing according to the received instructions.

  The route search unit 116 uses the map information, the current position information, and the destination information to search for a route from the current position indicated by the current position information to the destination indicated by the destination information. Then, the route search unit 116 acquires route information indicating the route.

  Specifically, the route search unit 116 normally applies current position information and destination information to map information. “Applying the current position information to the map information” means that the position on the map indicated by the current position information is set as the departure place. “Applying destination information to map information” means that a point on the map indicated by the destination information is set as the destination. Then, the route search unit 116 searches for a route from the departure point to the destination. At this time, the route search unit 116 normally uses the score of the road information included in the map information as the cost of the route. At this time, the route search unit 116 normally searches for a route with the minimum score.

  The route information is usually information having one or more pieces of position information indicating one or more positions through which the route passes. Further, the route information may be information composed of the one or more pieces of position information, for example. Further, the position and the position information may be a point and point information. The route information may include road information indicating a road connecting the one or more positions or points, for example.

  The route information may be information having one or more types of guidance related information, for example. Further, the route information may be information including one or more types of guidance related information, for example. The one or more types of guidance related information is usually static information. The static means that it does not change with the passage of time. In addition, the static guidance related information includes, for example, one or more position information indicating a position where the route passes, point information indicating one or more points where the route passes, and a road connecting the one or more positions or points. Road name information, route distance information indicating the distance of the route, intersection name information indicating the name of the intersection through which the route passes, intersection traveling direction information indicating the traveling direction at the intersection through which the route passes, and the like.

  Note that the route search usually uses a solution (algorithm) of the shortest route problem. “Solving the shortest path problem” is, for example, the Dijkstra method or the A * algorithm. Since these solutions are well-known, detailed description is abbreviate | omitted. Further, since the method and procedure for acquiring the route information are well known, detailed description thereof will be omitted.

  The guidance related information acquisition unit 117 acquires guidance related information using the route information. “Obtaining guidance-related information using route information” means obtaining guidance-related information included in route information, calculating guidance-related information using route information, and the like. The guidance related information acquisition unit 117 normally acquires guidance related information corresponding to the current position indicated by the current position information. The current position information is current position information acquired by the current position information acquisition unit 113. Further, the guidance related information corresponding to the current position is usually guidance related information of a content type corresponding to the current position. Further, the guidance related information to be calculated is usually information that changes according to the current position.

  For example, it is assumed that the guidance related information acquisition unit 117 is so close that a distance from the current position to the nearest intersection satisfies a predetermined condition. In such a case, the guidance related information acquisition unit 117 acquires guidance related information indicating the name of the nearest intersection from the route information, for example. At this time, for example, the guidance related information acquisition unit 117 uses the current position information and one or more pieces of point information indicating the intersection included in the route information to indicate the current position indicated by the current position information and the point information. Calculate the distance to the point. And the guidance relevant information acquisition part 117 acquires the information which shows the name of a point (intersection) from the point information which shows the intersection with the shortest distance with the present position and exists in the advancing direction.

  In addition, the guidance related information acquisition unit 117 calculates, for example, guidance related information indicating the scheduled time of arrival at the destination using the route information. At this time, for example, the guidance related information acquisition unit 117 acquires the distance of the remaining route from the current position to the destination from the route information. Then, the guidance related information acquisition unit 117 acquires the current moving speed. Then, the guidance related information acquisition unit 117 calculates the time to reach the destination using the distance of the remaining route and the current moving speed. Then, the guidance related information acquisition unit 117 calculates the guidance related information indicating the scheduled time of arrival at the destination by adding the time until arrival at the destination to the current time.

  In addition, the guidance related information acquisition unit 117 may acquire guidance related information according to, for example, a predetermined level of detail or a type of format. The detail level information and the format type information indicating the detail level and the format type are stored, for example, in a predetermined storage area. Further, the detail level information and the format type information may be information associated with the output destination information acquired by the output destination information acquisition unit 114, for example.

  For example, it is assumed that the detail information is “high”. The detail level information means that the detail level of the guidance related information is high. In such a case, the guidance related information acquisition unit 117 acquires guidance related information with a high degree of detail.

  For example, it is assumed that the detail information is “medium”. The detail level information means that the detail level of the guidance related information is medium. In such a case, the guidance related information acquisition unit 117 acquires guidance related information having a medium level of detail.

  For example, it is assumed that the detail information is “low”. The detail level information means that the detail level of the guidance related information is low. In such a case, the guidance related information acquisition unit 117 acquires guidance related information with a low level of detail.

  For example, it is assumed that the format type information is “image”. The format type information means that the format type of the guidance related information is an image. In such a case, the guidance related information acquisition unit 117 acquires guidance related information that is an image. For example, when a character indicating the name of the nearest intersection is acquired, the guidance related information acquisition unit 117 images the character and acquires the image. There is no limitation on the method or procedure for imaging characters.

  For example, it is assumed that the format type information is “character”. The format type information means that the format type of the guidance related information is a character. In such a case, the guidance related information acquisition unit 117 acquires guidance related information that is characters. For example, when a numerical value indicating the time of arrival at the destination is acquired, the guidance related information acquisition unit 117 converts the numerical value into a character and acquires the character. Any method or procedure for digitizing numerical values is acceptable.

  For example, it is assumed that the format type information is “numeric value”. The format type information means that the format type of the guidance related information is a numerical value. In such a case, the guidance related information acquisition unit 117 acquires guidance related information that is a numerical value. For example, when an image indicating the distance to the destination is acquired, the guidance related information acquisition unit 117 acquires a numerical value indicating the distance from the image. There is no limitation on the method or procedure for obtaining numerical values from the image.

  In addition, acquiring guidance related information according to the level of detail means, for example, performing processing according to the level of detail with respect to the acquired guidance related information. The process is usually a process for reducing the amount of information. The processing includes, for example, deleting unnecessary objects from the image, simplifying the image, deleting unnecessary characters from the characters, and performing fraction processing on the numerical values. The rounding process is, for example, rounding off or changing the number of significant digits (truncating digits below a specified digit). That is, the guidance related information acquisition unit 117 acquires guidance related information having the highest degree of detail, for example. And the guidance relevant information acquisition part 117 performs the process which reduces information amount with respect to the acquired guidance relevant information according to the detail information which detail information shows.

  In addition, the guidance related information acquisition unit 117 may acquire, for example, two or more guidance related information having different degrees of detail. In addition, the guidance related information acquisition unit 117 may acquire two or more guidance related information of different format types, for example.

  Note that a method and procedure for acquiring guidance-related information of a type corresponding to the current position are well known, and thus detailed description thereof is omitted.

  The output unit 118 outputs guidance related information corresponding to the route information. The guidance related information corresponding to the route information is usually guidance related information acquired by the guidance related information acquisition unit 117. The guidance related information can be said to be guidance related information acquired using route information, for example. Further, the guidance related information corresponding to the route information may be, for example, guidance related information included in the route information.

  Also, output refers to display on a display, projection using a projector, printing with a printer, sound output, transmission to an external device, accumulation in a recording medium, processing to other processing devices or other programs, etc. It is a concept that includes delivery of results. Further, the output may be, for example, two or more operations such as display and transmission, projection and sound output. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

  For example, when the output destination indicated by the output destination information received by the receiving unit 115 is the navigation device 11, the output unit 118 outputs, for example, guidance related information on the screen. In this case, the output unit 118, for example, in the detail level or format type indicated by the detail level information or the format type information associated with the output destination information among the guide related information acquired by the guide related information acquiring unit 117. Output matching guidance related information on the screen. In this case, for example, the output unit 118 may output the guidance related information acquired by the guidance related information acquisition unit 117 together with the route information acquired by the route search unit 116. In this case, for example, the output unit 118 does not output the same guidance related information as the guidance related information acquired by the guidance related information acquisition unit 117 among the guidance related information included in the route information.

  For example, when the output destination indicated by the output destination information received by the reception unit 115 is the display device 12, the output unit 118 transmits, for example, guidance related information to the display device 12. In this case, the output unit 118, for example, in the detail level or format type indicated by the detail level information or the format type information associated with the output destination information among the guide related information acquired by the guide related information acquiring unit 117. The matching guidance related information is transmitted to the display device 12.

  The display receiving unit 121 constituting the display device 12 receives guidance related information. Accepting guidance related information includes, for example, receiving guidance related information from an external device, obtaining guidance related information stored in a predetermined storage area, and the like. For example, the display receiving unit 121 receives guidance related information from the navigation device 11. In addition, for example, when the guidance related information is stored in a predetermined storage area, the display reception unit 121 acquires the guidance related information.

  Further, the display receiving unit 121 may receive an instruction such as power ON or power OFF, for example. When the display receiving unit 121 receives these instructions, the display device 12 normally performs processing according to the received instructions.

  The display output unit 122 outputs guidance related information. The guidance related information is guidance related information received by the display receiving unit 121. The output is usually screen output. Further, the display output unit 122 may output guidance related information according to, for example, a predetermined level of detail or a format type. The detail level information and the format type information indicating the detail level and the format type are stored, for example, in a predetermined storage area.

  For example, when the detail level and the format type of the guidance related information received by the display reception unit 121 are the same as the predetermined detail level and the format type, the display output unit 122 outputs the guidance related information. .

  Further, for example, when the detail level or format type of the guidance related information received by the display reception unit 121 is different from the predetermined detail level or format type, the display output unit 122 displays the detail level of the guidance related information. The information related to the guidance is processed so that the format type and the like match the predetermined detail level and format type. And the display output part 122 outputs the guidance relevant information after the said process. Note that this processing is, for example, processing performed by the guidance related information acquisition unit 117 for guidance related information. Moreover, the said process may be performed by the display guidance relevant information processing part which is not shown in figure, for example.

  Thereby, the display output unit 122 can output the guidance related information received by the display receiving unit 121 in an output mode different from the output mode of the guidance related information output by the output unit 118, for example. For example, the display output unit 122 can output the numerical value received by the display receiving unit 121 with a number of digits different from the number of significant digits of the numerical value output by the output unit 118.

  Further, the display output unit 122 may output the guidance related information so that the ratio of occupying the screen is as small as possible. In this case, the display output unit 122 outputs guidance related information to the right end or the left end of the screen, for example. Further, for example, when the guidance related information is 2 or more, the display output unit 122, for example, the two or more guidance related information so that the ratio of the screen occupied by the two or more guidance related information is as small as possible. Arrange and output information. The shape at the time of the arrangement is not limited. The shape at the time of the arrangement is, for example, a U-shape or an L-shape. In addition, the U-shape, the L-shape, and the like may be reversed in the vertical direction and the horizontal direction. Thereby, for example, when the display device 12 is a room mirror with a monitor, guidance related information can be output without impairing the function as a room mirror as much as possible. In other words, guidance related information can be output without hindering safety during driving as much as possible.

  The map information storage unit 111 and the output destination information storage unit 112 are preferably non-volatile recording media, but can also be realized by volatile recording media. Moreover, the process in which predetermined information is memorize | stored in the map information storage part 111 etc. does not ask | require. For example, the predetermined information may be stored in the map information storage unit 111 or the like via a recording medium, a communication line, an input device, or the like.

  Further, the output destination information acquisition unit 114, the route search unit 116, and the guidance related information acquisition unit 117 can be usually realized by an MPU, a memory, or the like. The processing procedure of the output destination information acquisition unit 114 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. Note that the output destination information acquisition unit 114 and the like may be realized by hardware (a dedicated circuit).

  Moreover, the input means such as information and instructions in the reception unit 115 and the display reception unit 121 may be anything such as a menu screen or a keyboard. The accepting unit 115 and the like can be realized by control software for a menu screen, a device driver for input means such as a keyboard, and the like.

  The output unit 118 and the display output unit 122 may or may not include an output device such as a display or a speaker. The output unit 118 and the like can be realized by driver software of an output device or driver software of an output device and an output device.

In FIG. 10, the shaded area is an area that functions as a room mirror. In this way, by minimizing the area in which the guidance related information is displayed, the function as a room mirror can be prevented from being impaired as much as possible.

  Next, it is assumed that the user operates the car navigation and performs an operation for changing the output destination. Then, similarly to the above, the output unit 118 outputs one or more pieces of output destination information as shown in FIG.

The accepting unit 115 accepts three pieces of output destination information associated with the detail level information.

  Thereafter, similarly to Example 2, the guidance related information acquisition unit 117 acquires guidance related information, and the output unit 118 outputs the guidance related information acquired by the guidance related information acquisition unit 117.

  Note that, as in Example 3 described above, the navigation device 11 may acquire output destination information indicating an output destination according to the boarding situation. In this case, the output destination information acquisition unit 114 holds, in advance, at least one output destination management information that is information in which the boarding condition and output destination information are associated with each other. The output destination management information may be stored in the output destination information storage unit 112, for example. And the output destination information acquisition part 114 acquires boarding condition information. And the output destination information acquisition part 114 judges whether the acquired boarding condition information satisfy | fills any one or more boarding condition conditions. And the output destination information acquisition part 114 acquires the output destination information corresponding to the boarding condition conditions which boarding condition information satisfies.

  The boarding status information may be acquired by, for example, a boarding status information acquisition unit (not shown). The boarding status information acquisition unit usually acquires boarding status information regularly. Further, the boarding status information acquisition unit, for example, accumulates the acquired boarding status information in a predetermined storage area. Moreover, a boarding status information acquisition part acquires boarding status information from an infrared sensor, a pressure sensor, etc., for example. In this case, the boarding status information acquisition unit may have these devices or may be realized by these devices. Further, the processing procedure of the boarding situation information acquisition unit is usually realized by software, and the software is recorded in a recording medium such as a ROM.

  As described above, according to the navigation system 1 according to the present embodiment, guidance related information can be output in different output modes corresponding to a plurality of output destinations. Further, according to the navigation system 1 according to the present embodiment, guidance related information can be dynamically switched according to a user instruction, the operation of the navigation device 11, the riding state of the automobile, and the like. Thereby, for example, guidance related information can be output to an output destination desired by the user and an output destination optimal for the user in an output mode optimal for the user.

  For example, when a user who is in a car is only a driver (only one person), during driving, the driver often looks at a room mirror rather than a monitor provided in a vehicle-mounted navigation device. In addition, the driver is unlikely to stare at the rearview mirror. Therefore, according to the navigation system 1 according to the present embodiment, for example, when the user who is in the car is only the driver, the detail provided on the monitor provided in the rearview mirror is not high (the amount of information is small). (Few) guidance related information can be output. This also allows the user to instantly confirm the content of the guidance indicated by the guidance related information while confirming the rear with the room mirror. Further, this makes it possible to output guidance related information without impeding safety during driving.

  Further, for example, when an in-vehicle navigation device is operating as a television, outputting guidance-related information superimposed on a video is not preferable because it interferes with a user who is watching the television. In such a case, according to the navigation system 1 according to the present embodiment, it is possible to determine the operation of the in-vehicle navigation device and output the guidance related information to an appropriate output destination. Thereby, the user can confirm the content of the guidance indicated by the guidance related information without being disturbed to view the television.

  Moreover, according to the navigation system 1 according to the present embodiment, the function as a room mirror is inhibited as much as possible by, for example, outputting guidance related information to the minimum necessary area in the screen of the room mirror with a monitor. In this way, guidance related information can be output.

  In the present embodiment, the display device 12 may have a navigation function. In this case, the display device 12 includes, for example, a display route search unit (not shown). In this case, the display receiving unit 121 receives map information, current position information, and destination information from the navigation device 11, for example. Then, the display route search unit searches for a route from the current position to the destination using the map information, the current position information, and the destination information received by the display receiving unit 121, and acquires route information indicating the route. . In addition, the display receiving unit 121 receives route guidance information corresponding to the route information acquired by the display route searching unit. Note that the processing and operations performed by the display route search unit are the same as the processing and operations performed by the route search unit 116, and thus description thereof is omitted.

  When the display device 12 includes a display route search unit, the display device 12 may further include, for example, a display map information storage unit and a display current position information acquisition unit (not shown). Since the information stored in the display map information storage unit is the same as the information stored in the map information storage unit 111, the description thereof is omitted. Further, since the process and operation performed by the display current position information acquisition unit are the same as the process and operation performed by the current position information acquisition unit 113, description thereof will be omitted. In this case, the display reception unit 121 receives destination information from the navigation device 11, for example. The display route search unit uses the map information stored in the display map information storage unit, the current position information acquired by the display current position information acquisition unit, and the destination information received by the display reception unit 121. The route from the current position to the destination is searched, and route information indicating the route is acquired. In addition, the display receiving unit 121 receives route guidance information corresponding to the route information acquired by the display route searching unit.
