  The storage unit 1 can store various types of information. The various types of information include, for example, map information to be described later, simplified guidance information, set route information, and type determination conditions.

  The map information storage unit 11 can store map information. Map information is information which comprises a map. The map information includes, for example, a map image (which may be called map symbol information), one or more objects displayed on the map, and a type of the object. The map information is, for example, in the KIWI format. However, the format, content, etc. of map information do not matter. The map information includes, for example, map symbol information indicating a symbol of a map, and term information having position information indicating a term and the position of the term on the map. The map symbol information is, for example, a bit map or vector data constituting a map. The term has an object (character string) described on the map. Further, the position information is information having latitude and longitude on a map, X, Y coordinate values on a two-dimensional plane, and the like. Also, the map information preferably has map symbol information and term information at each scale. An object is a place name, a building, a name of a scenic spot, a name of a place, a park, a mountain, etc. displayed on a map.

  The simplified guidance information storage unit 12 can store one or more pieces of simplified guidance information. The simplified guidance information is information constituting a simplified guidance. The simplified guidance information is, for example, one or more pieces of arrow information indicating a traveling direction. The arrow information is, for example, information indicating a right arrow, a left arrow, an up arrow, an arrow indicating a U-turn, and the like. The arrow information is, for example, an image. The arrow information is composed of, for example, a bitmap, vector data, and the like. Note that the data structure or content of the arrow information does not matter. In addition, the simple guide information usually does not have map symbol information.

  The set route information storage unit 13 can store set route information which is information indicating a set route. The set route information is usually information of a route acquired by the route searching process performed by the route searching unit 32. The set route information may be information input by the user. The set route information usually includes destination information. Destination information is information indicating a destination. Destination information is usually information of a destination input by the user.

  The type determination condition storage unit 14 is information for determining the type of guidance information to be output. The type determination condition storage unit 14 may store, for example, one or more type determination condition information having a type identifier and a condition. The type identifier is information for identifying the type of guidance information. The condition is, for example, "out of the route" or "on the route". The conditions are, for example, “traveling speed <= 5 km / h” and “traveling speed = 0”. The conditions are, for example, “traveling road type = high speed road”, “traveling road type = narrow street”, and “traveling road type = one-way road”.

  The receiving unit 2 receives an instruction, information, and the like from the user. The instruction or information is, for example, destination information, a route search instruction or the like.

  The means for inputting instructions, information, etc. may be anything such as a touch panel, remote control, keyboard, mouse, menu screen, or the like. The reception unit 2 can be realized by a device driver of input means such as a touch panel, control software of a menu screen, or the like.

The various processes are, for example, processes performed by a current position acquisition unit 31, a route search unit 32, a traveling state information acquisition unit 33, a determination unit 34, and the like, which will be described later.

  The current position acquisition unit 31 acquires the current position. The current position acquisition unit 31 acquires the current position using, for example, a GPS receiver. The current position acquisition unit 31 may acquire the current position of the navigation device using, for example, radio wave intensities from three or more base stations of the mobile phone. Note that there is no limitation on the means and method by which the current position acquisition unit 31 acquires the current position. The current position is usually an absolute position (latitude, longitude), but may be coordinate information or the like on map information. In addition, since the process of the present position acquisition part 31 is a well-known technique, detailed description is abbreviate | omitted.

  The route search unit 32 performs a route search. The route search unit 32 uses, for example, the map information of the map information storage unit 11 with the current position acquired by the current position acquisition unit 31 as a start point and the destination indicated by the destination information received by the reception unit 2 as an end point. Search and get route information. The algorithm of the route search unit 32 is not limited to the A * algorithm, the Dijkstra method, or the like. Since the process of the route search unit 32 is a known technique, the detailed description is omitted. The route information is information indicating a route, and is, for example, a set of points. The route search unit 32 normally accumulates the acquired route information in the set route information storage unit 13. The route information accumulated in the setting route information storage unit 13 is setting route information.

  The traveling state information acquisition unit 33 acquires traveling state information indicating a state related to traveling. The traveling state information is, for example, information based on the current position. The traveling state information is, for example, information that can be acquired from the current position and the map information. The traveling state information is, for example, information acquired using the current position acquired by the current position acquisition unit 31 and the set route information. The traveling state information is, for example, information indicating whether the current position deviates from the route indicated by the set route information. The traveling state information is, for example, information indicating that the vehicle is traveling on a route indicated by the set route information. The traveling state information is, for example, information indicating the type of road on which the vehicle is traveling (highway, narrow street, etc.). Further, the traveling state information is, for example, information not using the current position, and is information using the state of the moving body. The traveling state information is, for example, traveling speed. The traveling state information is, for example, an acceleration.

  The determination unit 34 determines whether the traveling state information acquired by the traveling state information acquisition unit 33 satisfies a predetermined condition.

  Here, the predetermined conditions include, for example, that the traveling state information deviates from the route indicated by the set route information, that the traveling speed is below the threshold or smaller than the threshold, that the traveling speed is above the threshold or higher than the threshold, etc. It is.

  That is, the determination unit 34 may determine, for example, whether the traveling state information is information indicating that the route indicated by the set route information has deviated. Further, the determination unit 34 may determine whether the traveling speed satisfies a predetermined condition.

  The output unit 4 outputs various types of information. The various information is, for example, guidance information, map information, and the like.

  Here, the output includes display on a display, projection using a projector, printing on a printer, sound output, transmission to an external device, storage in a recording medium, and other processing devices and other programs. It is a concept that includes the delivery of processing results.

  The guidance information output unit 41 outputs guidance information which is information of guidance corresponding to the current position acquired by the current position acquisition unit 31. The guidance information is information for navigation. The guidance information is information for supporting the movement toward the destination.

  The guidance information output unit 41 is a guidance corresponding to the current position, and outputs guidance information of a type corresponding to the traveling state information.

  The guidance information output unit 41 outputs guidance information of a type corresponding to the traveling state information. The types of guidance information include, for example, first-type guidance information using simplified guidance information described later, and second-type guidance information using map information. That is, the difference in the type of the guide information may be a difference depending on whether or not the guide information includes map symbol information. Further, types of guidance information include, for example, first-type guidance information by voice and second-type guidance information by display. That is, the difference in the type of guidance information may be the difference in the output medium (display, voice, display + voice, etc.) for outputting the guidance information. Moreover, that the kind of guidance information differs does not mean that the content of the information contained in guidance information differs. Also, if the type of the guidance information is different, does part of the information of the guidance information exist? It is not a difference such as missing or not. That is, it can be immediately determined by the user's five senses that the types of guidance information are different.

  The guidance information output unit 41 outputs guidance information of a type different from the guidance information being output, when the determination unit 34 determines that the traveling state information satisfies the predetermined condition.

  The guidance information output unit 41, for example, when the determination unit 34 determines that the traveling state information is information indicating that the route indicated by the set route information has deviated, guidance of a type different from the guidance information being output Output information

  The guidance information output unit 41 switches the output from the first type guidance information to the second type guidance information when the determination unit 34 determines that the traveling state information satisfies the predetermined condition. Alternatively, when the determination unit 34 determines that the traveling state information satisfies the predetermined condition, the guidance information output unit 41 switches the output from the second type guidance information to the first type guidance information.

  The guidance information output unit 41, for example, outputs simplified guidance information not having map information while traveling the route indicated by the set route information, and if it is determined that the route indicated by the set route information has deviated, the map information Output detailed guidance information that it has.

  The guidance information output unit 41 usually has a display. The display may be liquid crystal, plasma or the like, and the material does not matter. Also, the display is preferably a small screen of 6 inches or less. In addition, the size of the display is more preferably 5 inches or less. That is, the display is, specifically, a display such as a so-called watch-type terminal device (for example, a smart watch), a cycle computer, a small meter cluster, and the like.

  The type determination unit 411 determines the type of guidance information corresponding to the traveling state information acquired by the traveling state information acquisition unit 33. The type determination unit 411 acquires, for example, the type identifier corresponding to the traveling state information acquired by the traveling state information acquisition unit 33 using one or more of the type determination condition information of the type determination condition storage unit 14.

  The guidance information output unit 412 is guidance information corresponding to the type of guidance information determined by the type determination unit 411, and outputs guidance information corresponding to the current position.

  Although the storage unit 1, the map information storage unit 11, the simple guidance information storage unit 12, the set route information storage unit 13, and the type determination condition storage unit 14 are preferably non-volatile recording media, even volatile recording media It is feasible.

  There is no limitation on the process of storing information in the storage unit 1 or the like. For example, the information may be stored in the storage unit 1 or the like through the recording medium, or the information transmitted through the communication line may be stored in the storage unit 1 or the like. Alternatively, the information input via the input device may be stored in the storage unit 1 or the like.

  The processing unit 3, the route search unit 32, the traveling state information acquisition unit 33, and the determination unit 34 can be usually realized by an MPU, a memory or the like. Typically, the processing procedure of the processing unit 3 or the like is realized by software, and the software is stored in a storage medium such as a ROM. However, it may be realized by hardware (a dedicated circuit).

  The output unit 4, the guidance information output unit 41, and the guidance information output unit 412 may or may not be considered to include output devices such as a display and a speaker. The output unit 4 and the like can be realized by driver software of an output device or driver software of an output device and an output device or the like.

  Next, the operation of the navigation device will be described using the flowchart of FIG.

When the type of the guidance information output up to immediately before and the type of the guidance information determined in step S207 are different, it is assumed that the condition determined in advance is satisfied. When the type of the guidance information output up to immediately before and the type of the guidance information determined in step S207 are different, the determination unit 34 determines that the type of the guidance information is to be changed.
