Specifically, changing the level of detail of guidance related information is, for example, changing detailed guidance related information to simplified guidance related information or changing simplified guidance related information to detailed guidance related information. Such as changing. In addition, changing the content type of guidance related information includes, for example, changing the intersection information to all journey information, changing all the journey information to intersection information, changing all the journey information to route map information, For example, the route map information may be changed to all the process information. In addition, changing the type of guidance related information includes, for example, changing an image to a character, changing a character to an image, changing an image color, changing an image size, Changing the size of the character, changing the font of the character, etc.

  Further, changing the output arrangement of the guidance related information includes, for example, changing the output shape of the guidance related information or changing the output location of the guidance related information. The output shape is a shape of an area where guidance related information is output. Moreover, it can be said that an output shape is a shape by which guidance related information is arrange | positioned at the time of an output, for example. The output location is a location on the screen where guidance related information is output. Moreover, it can be said that the output location is, for example, one of the right end, the left end, the upper end, and the lower end of the screen on which the guidance related information is output.

  The output shape can be changed by, for example, outputting guidance related information output in a U-shape to an inverted U-shape, or outputting guidance-related information output in an inverted U-shape to a U-shape. To do. The U-shape means that the output shape is a U-shape. In addition, the inverted U shape means that the output shape is an inverted U shape. The output location can be changed, for example, by moving the guidance related information output at the right or left end of the screen to the other end, or by changing the guidance related information output at the upper or lower end of the screen to the other end. Moving to the other end, and moving the guidance related information output to the right end, left end, upper end or lower end of the screen to the other end.

That is, for example, when the guidance related information included in the display change instruction is output mode information, the display change instruction is an output mode change instruction. For example, when the guidance related information included in the display change instruction is output arrangement information, the display change instruction is an output arrangement change instruction.

  The output mode information is also information indicating the output mode of guidance related information. The output mode information is, for example, detail information, format type information, content type information, and the like.

  The output arrangement information is also information indicating the arrangement of guidance related information. The output arrangement information is, for example, output location information or output shape information. The output location information is information indicating the output location. The output location information is, for example, “right end”, “left end”, “upper end”, “lower end”, and the like. The output shape information is information indicating the output shape. The output shape information is, for example, “U”, “Reverse U”, “L”, “L”.

  The display change instruction may be a guidance switching instruction, for example. The guidance switching instruction is an instruction to switch between the entire process information and the intersection information. The guidance switching instruction is a kind of display change instruction. Furthermore, it can be said that the guidance switching instruction is a kind of output mode change instruction. In addition, switching between the entire process information and the intersection information means that, when the navigation output unit 117 described later or the output unit 123 described later outputs all the process information, the intersection information is output instead of the entire process information. However, when the intersection information is output, the entire stroke information is output instead of the intersection information.

  The information received by the navigation receiving unit 113 is, for example, destination information, sensing information, and the like. Sensing information is information acquired by sensing related to the movement of a moving object. The sensing information is, for example, the moving direction, moving speed, acceleration, angular velocity, and the like. When receiving sensing information, the navigation receiving unit 113 receives, for example, sensing information acquired by a navigation sensing information acquisition unit (not shown). The navigation sensing information acquisition unit is provided in the navigation device 11. When receiving destination information, the navigation receiving unit 113 receives, for example, the destination information selected by the destination selection instruction received by the navigation receiving unit 113.

  In addition, the navigation receiving unit 113 may receive an instruction other than the above, for example. The instructions other than the above are, for example, an instruction to turn on the power, an instruction to turn off the power, an instruction to execute a function provided in advance (hereinafter referred to as a function execution instruction as appropriate), and the like. Examples of the functions provided in advance include a TV function, an audio function, and a video function. When these instructions are received, the navigation device 11 performs processing according to the instructions.

  Further, the operation received by the navigation receiving unit 113 is usually an operation to the navigation device 11. The operation is, for example, a touch operation on a touch panel (screen) provided in the navigation device 11 or an operation on a button provided in the navigation device 11.

  Further, as described above, reception of instructions and information includes reception of instructions and information. When receiving an instruction or information, the navigation reception unit 113 receives an instruction or information transmitted from an external device including the room mirror monitor 12, for example. Further, in the following, it is assumed that the navigation reception unit 113 receives instructions, information, and the like that the room mirror monitor 12 transmits to the navigation device 11.

  The navigation route search unit 114 searches for a route from the current position indicated by the current position information to the destination indicated by the destination information using the map information, the current position information, and the destination information. The map information is map information stored in the navigation map information storage unit 111. The current position information is current position information acquired by the navigation current position information acquisition unit 112. The destination information is the destination information received by the navigation receiving unit 113. Then, the navigation route search unit 114 acquires route information indicating the route.

  Specifically, the navigation route search unit 114 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 navigation route search unit 114 searches for a route from the departure point to the destination. At this time, the navigation route search unit 114 normally uses the score of the road information included in the map information as the cost of the route. At this time, the navigation route search unit 114 normally searches for a route having 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 navigation guidance related information acquisition unit 115 normally acquires guidance related information using route information. For example, the navigation guidance related information acquisition unit 115 acquires guidance related information included in the route information. In addition, the navigation guidance related information acquisition unit 115 calculates guidance related information using route information, for example. In addition, the navigation guidance related information acquisition unit 115 may acquire guidance related information using map information, for example. For example, the navigation guidance related information acquisition unit 115 acquires a map corresponding to a predetermined area. The map corresponding to the predetermined area is, for example, a map having a predetermined size (dimension) and scale centered on the current position.

  The navigation guidance related information acquisition unit 115 normally acquires guidance related information corresponding to the current position indicated by the current position information. The guidance related information includes, for example, a map corresponding to the current location, a route corresponding to the current location, the name of the nearest intersection on the route, the distance to the nearest intersection on the route, and the nearest intersection on the route. The direction of travel, the distance to the destination, the scheduled time of arrival at the destination, etc. The current position information is current position information acquired by the navigation current position information acquisition unit 112. 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. Moreover, the timing which acquires the guidance relevant information corresponding to the present position is regular, for example.

  In addition, the navigation guidance related information acquisition unit 115 may acquire guidance related information that does not correspond to the current position indicated by the current position information, for example. The guidance related information is, for example, all process information. Moreover, the timing which acquires the guidance relevant information which does not respond to a present position is after acquisition of the route information by the navigation route search part 114, for example.

  In addition, since the method and procedure etc. which acquire the said guidance relevant information according to said present position, the guidance relevant information not according to the present position, etc. are well-known, detailed description is abbreviate | omitted.

  Further, the navigation guidance related information acquisition unit 115 may acquire guidance related information using sensing information, for example. The guidance related information is guidance related information corresponding to the current position and sensing information. The guidance related information according to the sensing information is, for example, a map according to the traveling direction, a destination arrival scheduled time according to the speed, and the like. The map corresponding to the traveling direction is a map whose upward direction is the traveling direction. Further, the destination arrival scheduled time according to the speed is a scheduled time of arrival at the destination calculated based on the current position and the current moving speed.

  Further, the navigation guidance related information acquisition unit 115 may acquire the 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.

  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 navigation guidance related information acquisition unit 115 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 navigation guidance related information acquisition unit 115 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 navigation guidance related information acquisition unit 115 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 navigation guidance related information acquisition unit 115 acquires guidance related information that is an image. For example, when a character indicating the name of the nearest intersection is acquired, the navigation guidance related information acquiring unit 115 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 navigation guidance related information acquisition unit 115 acquires guidance related information that is characters. For example, when a numerical value indicating the time of arrival at the destination is acquired, the navigation guidance related information acquisition unit 115 converts the numerical value into a character and acquires the character. Any method or procedure for digitizing numerical values is acceptable.

  Further, for example, it is assumed that the format type information is “numerical value”. The format type information means that the format type of the guidance related information is a numerical value.

  In the output mode management information having the above-described driving status condition and output mode information, the driving status condition may be, for example, a deletion determination condition. In this case, the output mode information is information indicating that guidance related information (simplified guidance related information) with a small amount of information is output.

  Further, “outputting guidance related information with a small amount of information instead of the guidance related information being output” means, for example, when one or more types of guidance related information is being output, From the guidance related information, instead of hiding at least one type of guidance related information of the guidance related information, or replacing at least one type of guidance related information of the one or more types of guidance related information Alternatively, information with a small amount of information may be output. The information having a smaller amount of information than the guidance related information includes, for example, road traffic information, the remaining distance to the destination, the time to the destination, the scheduled time of arrival at the destination, and the like. The road traffic information is information provided by so-called VICS (registered trademark), for example. That is, the information having a smaller amount of information than the guidance related information may be information other than the guidance related information or may be guidance related information.

  Further, the output unit 123 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 reception unit 121 are the same as the predetermined detail level and the format type, the output unit 123 outputs the guidance related information.

  For example, when the detail level or format type of the guidance related information received by the reception unit 121 is different from a predetermined detail level or format type, the output unit 123 displays the detail level or format of the guidance related information. The guidance related information is processed so that the type or the like matches the predetermined level of detail or type. And the output part 123 outputs the guidance relevant information after the said process. Note that this processing is, for example, processing performed by the navigation guidance related information acquisition unit 115 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.

  Moreover, the output part 123 outputs alerting | reporting information, for example, when the driving | running | working condition information which the reception part 121 received satisfy | fills judgment conditions. Hereinafter, the determination condition is appropriately set as a notification determination condition. The notification determination condition is a condition related to the traveling state of the moving body. In addition, it can be said that the notification determination condition is a condition related to the traveling state information. The notification determination condition is also a condition for determining to notify the user. Moreover, since the content and format of the notification determination condition are the same as the content and format of the driving condition, description thereof will be omitted.

  For example, it is assumed that the notification determination condition is that the moving body is likely to collide with an obstacle. Further, it is assumed that the traveling state information satisfies the notification determination condition. In such a case, for example, the output unit 123 preferably outputs notification information that is an image around the moving body. Further, for example, it is assumed that the notification determination condition is that the moving body has entered a parking area or a service area of an expressway. Further, it is assumed that the traveling state information satisfies the notification determination condition. In such a case, for example, the output unit 123 preferably outputs notification information that is an image of a map of a parking area of a highway or a service area where a moving body has entered. Further, the notification determination condition is that the road on which the moving body is traveling is a sharp curve or a slope. Further, it is assumed that the traveling state information satisfies the notification determination condition. In such a case, it is preferable that the output unit 123 outputs notification information that is a warning sound, for example.

  Moreover, the output part 123 may output the alerting | reporting information according to the driving | running | working condition information which the reception part 121 received, for example. At this time, for example, the output unit 123 acquires notification information corresponding to the traveling state of the moving object indicated by the traveling state information. Since the method and procedure for acquiring the notification information have been described, the description thereof will be omitted. Then, the output unit 123 outputs the acquired notification information.

  In the notification management information having the above-described traveling condition and notification information, the traveling condition is usually a notification determination condition.

  Further, the output unit 123 may output the notification information received by the receiving unit 121, for example. In addition, the output unit 123 may output the notification information having the content indicated by the notification content information received by the reception unit 121, for example. In this case, for example, the output unit 123 acquires the notification information having the content indicated by the notification content information from a predetermined storage area. Then, the output unit 123 outputs the notification information.

  Note that in the above, the output unit 123 retains in advance information (for example, deletion determination conditions, notification determination conditions, etc.) used by the output unit 123 to output guidance related information, notification information, and the like. . The information may be stored in a predetermined storage area, for example. In addition, on the screen on which the guidance related information is output, an area other than the area where the guidance related information is output functions as a room mirror.

  In addition, the output unit 123 transmits information, instructions, and the like to the navigation device 11. The information is, for example, sensing information acquired by the sensing information acquisition unit 122. The instruction is an instruction received by the receiving unit 121, for example.

  The output unit 123 may include, for example, a control unit (not shown), an output unit, and a transmission unit. In this case, the control means normally controls the output of guidance related information and notification information by the output means. That is, for example, when the receiving unit 121 receives guidance related information, the control unit instructs the output unit to output the guidance related information on the screen. The output means outputs the guidance related information on the screen in accordance with the instruction. For example, when the reception unit 121 receives a display change instruction, the control unit instructs the output unit to change the display based on the guidance related information in accordance with the display change instruction. Then, the output means changes the display based on the guidance related information in accordance with the instruction. Further, the output means normally performs screen output of guidance related information, screen output of notification information, and the like in accordance with instructions from the control means. In addition, the transmission unit normally transmits the sensing information acquired by the sensing information acquisition unit 122, the instruction received by the reception unit 121, and the like to the navigation device 11.

  Note that the input means such as information and instructions in the navigation receiving unit 113 and the receiving unit 121 may be anything such as a menu screen or a keyboard. The navigation receiving unit 113 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.

  In addition, the navigation route search unit 114 and the navigation guidance related information acquisition unit 115 can be usually realized by an MPU, a memory, or the like. Also, the processing procedure of the navigation route search unit 114 and the like is usually realized by software, and the software is recorded in a recording medium such as a ROM. The navigation route search unit 114 and the like may be realized by hardware (a dedicated circuit).

  The navigation output unit 117 and the output unit 123 may or may not include output devices such as a display and a speaker. The navigation output unit 117 or the like can be realized by output device driver software, or output device driver software and an output device.

  (Step S309) The navigation guidance related information acquisition unit 115 determines whether it is the timing of acquisition of guidance related information. The timing is, for example, periodically or when approaching an intersection (when the distance to the intersection is close enough to satisfy a predetermined condition).

In this specific example, it is assumed that the navigation device 11 and the room mirror monitor 12 are mounted on an automobile. In addition, the navigation device 11 is assumed to be a car navigation system (hereinafter referred to as car navigation as appropriate). Further, the room mirror monitor 12 is assumed to be a room mirror (hereinafter referred to as a room mirror as appropriate) mounted in an automobile. Hereinafter, the operations described in the previous example will be omitted as appropriate in the later examples.
