  According to the present invention, road information including at least one of road network data and road map data defining a road network is stored, current position information is acquired, and two points are obtained based on a history of current position information. A section that includes a route between two set points based on the history of road information and current position information, and includes at least one of the distance and the undulation status of the route together with the set route identification information The information is acquired and stored in the storage unit. Based on the road information, the guide route from the departure point to the destination that satisfies the guide route condition including the departure point and the destination is set. From the stored section information , Search for section information in which at least one of the predetermined section of the set guide route and the distance and undulation situation is the same or approximate, and include a guide route in which the searched section information is associated Based on the value information, a guidance route in association with the section information and outputs it to the output unit. Thereby, according to this invention, there exists an effect that the standard information according to a user's sense can be provided appropriately also in the place etc. without a land intuition. For example, in Patent Document 1, (1) Among the landmarks in the vicinity of the recommended route that are mechanically extracted, the landmarks that have not been visited frequently, such as landmarks that have not been visited, are not always recognized. Marks may be included, and there is a problem that it is not always possible to provide associative information for grasping the perspective for the user. However, according to the present invention, 2 is based on the history of the current position information. Since the route between points is extracted, this problem can be solved. In Patent Document 1, (2) in order to be extracted as a landmark, a route search process must be performed from the direction near the route, or a landmark must exist near the road that is easily selected as a route. Landmarks that do not exist in the vicinity of the recommended route are not stored in the route information. In particular, route guidance processing is often not performed if the route is frequently traveled by a user. Therefore, it is difficult to store route information for landmarks on the route, such as around the home, which is originally desirable as association information. Even if it is stored as associative information by chance when searching for a route, it is not provided as associative information if it is not extracted a predetermined number of times or more, and even if it is a landmark that is well known but is not frequent However, according to the present invention, since the route between two points is extracted based on the history of the current position information, the problem on the landmark on the route that is difficult to extract is difficult to be provided as association information. Can be solved. Further, in Patent Document 1, (3) since associative information corresponding to the distance from the current location to the destination is displayed for the entire route, a section familiar to the user, such as the second half of the route, or a plurality of movements There is a problem that the user provides associative information up to a well-known section on the guidance route, such as a section of a train in the route of the means. Since the section information which becomes a standard for the section is provided, this problem can be solved.

  Further, the navigation system of the present invention stores road information including at least one of road network data and road map data defining a road network, and at least a start point and an end point defined by point information input by a user The route between the two points is set based on the road information, and the section information including at least one of the distance and the undulation status of the route together with the set route identification information is acquired and stored in the storage unit, Based on the road information, set the guide route from the departure point to the destination that satisfies the guide route condition including the departure point and the destination, and set the predetermined route of the set guide route from the section information stored in the storage unit Section information in which at least one of the distance and the undulation situation is the same or approximate, and includes a guidance route in which the searched section information is associated Based on the value information, a guidance route in association with the section information and outputs it to the output unit. Thereby, according to this invention, there exists an effect that the standard information matched with a user's sense can be provided appropriately. For example, in the navigation device described in Patent Document 1, (1) a problem that the extracted landmark does not grasp the sense of distance, or (2) a well-known landmark is recorded because route guidance is not performed. However, according to the present invention, since the route between the two starting points and the terminal points input by the user is used, this problem can be solved. it can. Moreover, in patent document 1, although there existed a problem which provided associative information even to well-known routes, such as a house periphery, in a guidance path | route, according to this invention, it targeted for the predetermined area among guidance paths. This section can be solved because it provides section information as a guide.

  According to the present invention, the road information further includes POI information, and two POIs are selected as two points from the POI information of the road information based on the history of the current position information. It is possible to set between two POIs on the travel history, which is preferable when determining a section, and it is possible to provide guide information more accurately.

  Further, according to the present invention, since the visited POI is selected as a point based on the history of the current position information, an appropriate POI can be selected based on the traveling history and the guide information can be provided accurately. There is an effect.

  In addition, according to the present invention, when the current position based on the history of the current position information exists continuously for a predetermined number of times around the POI or in the POI area, it is determined that the user has visited the POI. By setting the POI that has stayed for a predetermined time or more that is likely to have actually stopped as one of the two points, it is possible to set a section serving as a guide more accurately.

  In addition, according to the present invention, since the POI visited at a frequency of a certain number of times or a predetermined value or more is selected based on the history of the current position information, the number of visits and the visit frequency of the user can be considered. By setting a POI familiar to the user, it is possible to set a section serving as a guide more accurately.

  In addition, according to the present invention, a POI of a type or attribute that satisfies the conditions set by the user is selected based on the history of the current position information. For example, a familiar POI that matches the user's preference can be set. Thus, there is an effect that it is possible to set the reference section more appropriately.

  Further, according to the present invention, the road information further includes POI information, and the two POIs of the type or attribute that satisfy the conditions set by the user corresponding to the start point and the end point specified by the point information are Since it is selected as a point, for example, by setting a familiar POI corresponding to the user's preference corresponding to the start point and end point specified by the user, it is possible to set a section serving as a reference more accurately. There is an effect.

  In addition, according to the present invention, since a route between two points is searched based on the network data of road information, an optimum route can be searched and an objective distance between the two points can be set. It is possible to set an interval that can be easily understood by anyone.

  Further, according to the present invention, the route specified by the user is set by transmitting control data for allowing the user to specify the route between the two points based on the road map data of the road information. Therefore, when the user designates a route that is a guideline, a route that is well known by the user can be designated, and an easily understandable guideline can be provided.

  In addition, according to the present invention, since the predetermined section of the set guide route is set based on the moving means, for example, a section where provision of a guide is unnecessary, such as a section using public transportation such as a train. Except for, there is an effect that it is possible to provide an indication of a section that is considered necessary for the user. More specifically, if you provide a guideline for the walking section, users can quickly decide whether to walk or use a taxi, and avoid regretting that they are tired after they start walking. it can. On the other hand, if you know that the route you don't know is about the same distance as you walked, you can choose to walk a little harder.

  In addition, according to the present invention, the predetermined section of the set guide route is set based on the history of the current position information, the section information, or the route specified by the user. If you are familiar with the user and do not need to provide a guide, such as a walking section or a section set as a guide route guideline, use the guideline of the section that the user thinks necessary. There is an effect that it can be provided.

  Further, according to the present invention, when section information that is the same or approximate cannot be searched, section information that is close outside the same or approximate range is searched, so even if there is no section that satisfies the condition Since the result of the next point can be provided as reference information, there is an effect that the user can grasp a rough guide.

  Further, according to the present invention, since the distance or the undulation situation is compared between the section information and the guide route and output to the output unit based on the guide information, the user compares the guide route with the guide section. Thus, it is possible to provide an easy-to-imagine sense of distance and undulations of the guidance route.

The POI information may be included as part of the road network data or road map data described above.

  The position database 206b is position information storage means for storing position information (including current position information and point information (hereinafter the same)) received from the terminal device 100. That is, the position database 206b functions as a current position information storage unit that stores a history of current position information received from the terminal device 100 when storing the current position information, and from the terminal device 100 when storing point information. It functions as point information storage means for storing received point information. Here, the “point information” is information that defines at least two points serving as a starting point and an ending point. Note that the location database 206b may temporarily store location information. The position database 206b may store position information for each user using user identification information or the like.

  The section database 206c is section information storage means for storing section information including at least one of the distance and the undulation status of the route together with the route identification information. For example, the section information indicating the undulation status may be information indicating a height difference in the section, information including a gradient, or information indicating the presence or absence of stairs and the number of steps. The section database 206c may store section information for each user using user identification information or the like. Here, FIG. 2 is a diagram illustrating an example of section information stored in the section database 206c.

  As an example, as illustrated in FIG. 2, the section database 206c stores section information in which a section from a departure point to a destination, a distance, and a travel date / time are associated with each other. As described above, the section information includes information such as the distance from the departure point to the destination and the route identification information such as the travel date and time and the like.

  The control unit 202 has an internal memory for storing a control program such as an OS (Operating System), a program that defines various processing procedures, and necessary data. And the control part 202 performs the information processing for performing various processes with these programs. The control unit 202 is functionally conceptually configured as a position information receiving unit 202a, a spot setting unit 202b, a route setting unit 202f, a section information acquisition unit 202g, a guide route condition receiving unit 202h, a guide route setting unit 202i, and a section information search unit 202j. , And a guide information transmission unit 202k.

  Among these, the position information receiving unit 202a is position information receiving means for receiving position information such as current position information and point information transmitted from the terminal device 100. Here, the location information receiving unit 202a may receive user identification information transmitted from the terminal device 100 together with the spot information. Further, the location information receiving unit 202a may acquire user identification information by analyzing a communication route of the network 300 or the like. The position information receiving unit 202a may store the received position information in the position database 206b for each user using the user identification information or the like, and the section information in association with the date / time information such as the reception date / time or the travel date / time. May be stored.

  The point setting unit 202b is a point setting unit that sets two points based on position information (history of current position information or point information) received by the position information receiving unit 202a and stored in the position database 206b. . In addition, since the point information defines two points as a starting point and an ending point, it suffices to set two points as they are. However, in the following embodiments, the point setting unit 202b (formally ) It may be explained that the setting is made by selecting two points. Further, the point setting unit 202b may be set by selecting a POI of a type or attribute that satisfies a condition set by the user based on the point information. In the present embodiment, selecting and setting from a plurality of cases may be referred to as selection. In addition, since the route can be set based on the current position information history (travel history) if the (two) points to be selected are along the travel history, the location setting unit 202b has a location that has no travel history (that has been visited). No POI etc.) may be selected. Further, the spot setting unit 202b may set two POIs of types or attributes that satisfy the conditions set by the user corresponding to the starting point and the ending point specified by the spot information as the two spots. Further, the point setting unit 202b may select two POIs as two points from the POI information of the road information based on the history of the current position information.

  Here, the spot setting unit 202b may select the visited POI as a spot based on the history of the current position information. Here, examples (1) to (3) of the visit determination method by the point setting unit 202b will be described below. (1) As an example, the point setting unit 202b visits the POI when the current position based on the history of the current position information exists continuously in the POI area or in the POI area for a predetermined number of times or more. It may be determined that the number of visits to the POI is one. (2) As another example, the point setting unit 202b determines that the number of arrivals within the POI area or within the POI area after a predetermined period (with a predetermined period) is one visit. Also good. For example, when going around and around the POI, it is usually counted many times, but if the predetermined period is set to 24 hours from midnight to 12:00 pm, the point setting unit 202b may be counted as one visit no matter how many times it reaches in one day. (3) Further, as another example, even if the current position information is not obtained for a predetermined period, the point setting unit 202b is again in the vicinity of the point indicated by the last acquired current position information after a predetermined time. When the position information is acquired, it may be determined that the POI has been visited. For example, in the case of car navigation or the like, the power is turned off after arrival at the destination and the current position is not measured. However, after the power is turned on again, the point setting unit 202b displays the last history of the current position information. Based on the current position information, the newly acquired current position information is collated. When the current position information is within a predetermined range, the target POI is set to 1 even if the current position information is not continuously acquired more than a predetermined number of times. It may be determined that the visit has been made once.

  Then, the point setting unit 202b may determine a visit based on the history of the current position information as described above, and may select a POI that has visited at a certain number of times or more than a predetermined value. Here, the spot setting unit 202b may count up the determined number of visits, and may calculate the visit frequency and the like. Then, the spot setting unit 202b may select a POI that is visited at a certain number of visits (for example, once) or a visit frequency greater than or equal to a predetermined value. As a result, the point setting unit 202b can select the appropriate POI by calculating the number of visits such as the day of the visit and the visit frequency such as the number of visits per week. Here, as shown in FIG. 1, the spot setting unit 202b may include a POI extraction unit 202c, a POI selection unit 202d, and a POI designation unit 202e.

  Among these, the POI extraction unit 202c is a POI extraction unit that extracts candidate POIs from the road database 206a based on the position information stored in the position database 206b. The POI extraction conditions extracted by the POI extraction unit 202c are within a predetermined distance range from the position indicated by the position information, and the history of position information exists continuously in the POI area or in the POI area for a predetermined number of times. The location where the user visits frequently because the number of visits based on the history of location information is more than a certain number or the visit frequency based on the number of visits is more than a certain frequency. , POI type and attribute may be set.

  The POI selection unit 202d is a POI selection unit that selects two POIs at both ends of the section of the section information from the POIs extracted by the POI extraction unit 202c. For example, when four POIs of point A (starting place), point B (route 1), point C (route 2), and point D (destination) are extracted by the POI extraction unit 202c, the POI The selection unit 202d can select a maximum of six sections of AB, AC, AD, BC, BD, and CD. Alternatively, the POI selection unit 202d selects a section A-D between the departure point (point A) and the destination (point D) as a section of section information, and a section between transit points (for example, section BC) is selected. Since it is not necessary as a section of section information, it does not need to be selected. That is, since the POI extraction unit 202c automatically acquires all the routes, the two POIs may be automatically selected so as to be a combination of all points, and only some of these routes are selected. In order to obtain the two POIs, two POIs may be selected according to a selection condition (for example, a combination condition at both ends such as a departure point and a destination other than a waypoint).

  The POI designating unit 202e is a POI designating unit that accepts user designation in POI extraction or selection. For example, the POI specification unit 202e transmits the control unit for the user to specify the extraction conditions and selection conditions described above, or the POI to be extracted and the POI to be selected, to the terminal device 100, so that the user can input the input unit 116. The specification information input via the interface is received, and based on the received specification information, the extraction conditions, selection conditions, POI, etc. used by the POI extraction unit 202c or the POI selection unit 202d are set. As a specification mode by the user, the POI extracted or selected by the POI extraction unit 202c or the POI selection unit 202d may be determined by the user, or unnecessary combinations may be excluded. In the above example, the example in which the extraction process by the POI extraction unit 202c and the selection process by the POI selection unit 202d are performed separately has been described. However, the present invention is not limited to this, and the point setting unit 202b integrates these processes. May be performed. For example, the spot setting unit 202b may perform the integration process using an integration condition obtained by integrating the extraction condition and the selection condition described above.

  The route setting unit 202f is route setting means for setting a route between two points (two POIs) set by the point setting unit 202b based on road information stored in the road database 206a. Here, the route setting unit 202f may set a route between two points based on the road information stored in the road database 206a and the history of the current position information stored in the position database 206b. The route setting unit 202f may search for a route between two points based on road network data of road information stored in the road database 206a. If an optimum route can be set by route search, an objective route that is easy for anyone to understand can be set. In addition, the route setting unit 202f transmits control data that allows the user to designate a route between two points to the terminal device 100 based on the road map data of the road information stored in the road database 206a. May receive the designation information input via the input unit 116 (for example, information specifying the waypoint on the map) and set the route specified by the user. Thereby, it is possible to set a route that is easily understood by the user. Here, when two points are set by the point setting unit 202b based on the history of the current position information, the route setting unit 202f sets a waypoint based on the history of the current position information and searches for a route. May be performed. On the other hand, when two points are set by the point setting unit 202b based on the point information, the route setting unit 202f determines the route based on the road information stored in the road database 206a (since there is no travel history). It may be set. The user may be able to change the route set based on the current position information history (travel history) or road information, or the optimum route can be determined by performing processing based on the travel history and route search in parallel. For example, the route setting unit 202f may set a route by arbitrarily combining these processes.

  Further, the section information acquisition unit 202g acquires section information including at least one of the distance of the route and the undulation status (e.g. height difference) together with the identification information of the route between the two points set by the route setting unit 202f. Section information acquisition means stored in the section database 206c. Here, the identification information acquired by the section information acquisition unit 202g is some information for allowing the user to identify the route between the two points set by the route setting unit 202f, and the starting point and end point of the route. Information (point name, etc.), information indicating a route from the start point to the end point, the date and time of the travel history (start point departure time, end point arrival time, etc.), period, and the like. Here, the section information acquisition unit 202g may acquire distance or undulation information from road information in the road database 206a. The section information acquisition unit 202g may store the section information for each user in the section database 206c using the user identification information or the like.

  The guide route condition receiving unit 202h is guide route condition receiving means for receiving a guide route condition including a departure place and a destination, transmitted from the terminal device 100. The guide route condition receiving unit 202h may receive the user identification information transmitted together with the guide route condition from the terminal device 100, or may acquire the user identification information by analyzing the communication route of the network 300 or the like. Good.

  The guide route setting unit 202i sets the guide route from the departure point to the destination that satisfies the guide route condition received by the guide route condition receiving unit 202h based on the road information stored in the road database 206a. It is a guidance route setting means. Here, the guide route searched by the guide route setting unit 202i may be, for example, a combination of road links indicating the route, and obtains an optimal guide route based on the link cost of the road link indicating the route. May be. For example, the guidance route setting unit 202i may search for the optimum route such as the shortest route or the shortest time route from the departure point to the destination based on the road network data of the road information stored in the road database 206a. In addition, the guide route setting unit 202i transmits control data that allows the user to designate or change the guide route to the terminal device 100 based on the road map data of the road information stored in the road database 206a. May receive the designation information input via the input unit 116 (for example, information specifying the waypoint on the map) and set the guidance route specified by the user.

  In addition, the section information search unit 202j selects a predetermined section of the guide route set by the guide route setting unit 202i, distance, and undulation status from the section information acquired by the section information acquisition unit 202g and stored in the section database 206c. Section information search means for searching for section information in which at least one of them is the same or approximate. Here, a threshold value that defines a range that is the same or approximate may be provided (for example, a predetermined distance in the case of a distance, a predetermined height difference in the case of undulations, or the like). The section information search unit 202j may search for section information that is close outside the same or approximate range when the same or approximate section information cannot be searched. Thereby, even if there is no section information that is the same or approximate, section information of a section that serves as a reference can be provided, so that the user can grasp a rough sense of perspective. The section information search unit 202j may search for section information by prioritizing a distance (the closest one), the number of times of travel (a thing that is frequently traveled), a travel date and time (new one), The search may be performed by comprehensively judging these by weighting or the like.

  Here, the predetermined section of the guide route is a section that is considered to require provision of section information as a guide, and is a section that excludes sections that are considered unnecessary for the user. For example, the section information search unit 202j may set a predetermined section of the guide route set by the guide route setting unit 202i based on the moving unit. As an example, when the guide route set by the guide route setting unit 202i includes a walking section and a section using public transportation, the distance traveled by the public transportation or a guideline such as the undulation situation Since provision is considered unnecessary, the section information search unit 202j may exclude a section using public transportation and set a walking section as a predetermined section to be searched based on the moving means. In addition, the section information search unit 202j selects a predetermined section of the guide route set by the guide route setting unit 202i, the history of the current position information stored in the position database 206b, the section information stored in the section database 206c, Or you may set based on the path | route designated by the user by control of the path | route setting part 202f. As an example, the section information search unit 202j is a section in which a user frequently passes a section where a history of current position information stored in the position database 206b exists (for example, a section where a history of traveling a predetermined number of times or more remains). May be excluded as being unnecessary. Further, the section based on the section information stored in the section database 206c is the section set by the section information search unit 202j based on the current position information history (running history) or point information designated by the user. It may be excluded that provision of a guide is unnecessary. In addition, the section information search unit 202j may exclude the section of the route designated by the user under the control of the route setting unit 202f as the guideline is not provided because the route is set by the user as a guideline. Good. In addition, the section information search unit 202j transmits control data for designating or changing a predetermined section to the user to the terminal device 100, whereby designation information (for example, on a map) input by the user via the input unit 116 is transmitted. The information specified by the both ends of the predetermined section may be received and the section specified by the user may be set. Note that a plurality of the setting conditions described above may be used in combination.

  The guide information transmitting unit 202k is a guide information transmitting unit that transmits guide information including a guide route associated with the section information searched by the section information searching unit 202j to the terminal device 100.

[Configuration of Terminal Device 100]
Further, in FIG. 1, the terminal device 100 transmits position information (current position information or point information) to the server device 200, transmits a guide route condition to the server device 200, and is transmitted from the server device 200. , And based on the received guideline information, the guidance route is output to the output unit 114 in association with the section information. The terminal device 100 is, for example, a commercially available information processing device such as a desktop or notebook personal computer, a mobile terminal device such as a mobile phone, a smartphone, a PHS, and a PDA, and a navigation terminal that performs travel route guidance and the like. (For example, a car navigation device). Here, the terminal device 100 may be equipped with an Internet browser or the like, or may be equipped with a route guidance application, a transfer guidance application, an information search application, or the like. Further, the terminal device 100 may include a position acquisition unit 112 having a GPS function, an IMES function, or the like so that the current position can be acquired in real time. In addition, the terminal device 100 includes an output unit 114.

  Here, the output unit 114 may be, for example, display means for performing screen display (for example, a display and a monitor configured with liquid crystal, organic EL, or the like). The output unit 114 may be an audio output unit (for example, a speaker) that outputs audio data as audio. In addition, the terminal device 100 may include an input unit 116 (for example, a key input unit, a touch panel, a keyboard, a microphone, and the like) that performs input of guidance route conditions, designation information, and the like. The input / output control interface unit 108 controls the position acquisition unit 112, the output unit 114, the input unit 116, and the like.

  Further, the position acquisition unit 112 may be, for example, a signal receiving unit that receives a position information signal transmitted from the position transmission device 500. Here, the position transmitting device 500 may be a GPS device that transmits a position information signal (GPS signal). Further, the position transmission device 500 may be a base station (for example, a mobile phone, a car phone, a PHS base station, or the like) that is a device for performing wireless communication with the terminal device 100. Further, the position transmission device 500 may be an IMES device that realizes an IMES (Indoor Message System) technology that enables indoor positioning using a position information signal having characteristics similar to those of a GPS signal. The IMES technology is a system developed from the framework of the quasi-zenith satellite, which is a positioning satellite system.

  Further, the position transmission device 500 may be a GPS repeater that transmits a GPS signal received outdoors indoors. Further, the position transmitting device 500 is arbitrarily installed on each floor of a building (for example, a multilevel parking lot) or an underground structure (for example, a subway station, an underground shopping area, an underground communication passage, and an underground parking lot). A small transmitter may be used. In addition, self-position information (position ID etc.) according to an installation place is allocated to this small transmitter. When the terminal device 100 enters the communicable range, the terminal device 100 receives the self-position information transmitted from the small transmitter as a position information signal. The communication method at this time may be, for example, various short-range wireless methods such as an RFID (Radio Frequency Identification) tag system and Bluetooth (registered trademark), an infrared communication method, and the like. Further, the position transmission device 500 may be a wireless LAN access point. In the present embodiment, the location acquisition unit 112 may receive wireless LAN signals and acquire access point identification information.

[Navigation system processing]
Next, an example of processing of the navigation system according to the first embodiment configured as described above will be described in detail with reference to FIGS. FIG. 3 is a flowchart illustrating an example of basic processing of the navigation system according to the first embodiment.

  As shown in FIG. 3, first, the location information acquisition unit 102a of the terminal device 100 acquires location information (step SA-1). For example, the position information acquisition unit 102a may control the user to input point information that defines at least two points that are a starting point and an end point via the input unit 116. The current position information of the terminal device 100 calculated from the position information signal received from the device 500 may be acquired. As an example, the position information acquisition unit 102a may acquire point information such as position coordinates input by the user via the input unit 116. For example, the position information acquisition unit 102a allows the user to specify on the display screen based on the map information displayed on the output unit 114 via the input unit 116 (for example, a designation operation on the touch panel type output unit 114). The coordinates may be acquired as point information. Note that the location information acquisition unit 102a does not acquire location information regarding a single location, but location information (for example, designated by the user) regarding a route between two locations (such as an actual route for voice guidance). A reference route from the home to the nearest station may be acquired.

  Then, the location information transmission unit 102b of the terminal device 100 transmits the location information acquired by the location information acquisition unit 102a to the server device 200 (step SA-2).

  Then, the location information receiving unit 202a of the server device 200 receives the location information transmitted from the terminal device 100 (step SA-3). Here, the location information receiving unit 202a may receive the user identification information transmitted together with the point information from the terminal device 100, and may acquire the user identification information by analyzing the communication route of the network 300 or the like. . The position information receiving unit 202a may store the received position information such as current position information and point information in the position database 206b in association with the user identification information.

  Then, the point setting unit 202b of the server device 200 sets two points based on the position information (history of current position information or point information) received by the position information receiving unit 202a and stored in the position database 206b ( Step SA-4). Here, the point setting unit 202b may select two POIs as two points from the POI information of the road information based on the position information. Further, the spot setting unit 202b may select the visited POI as a spot based on the history of the current position information. For example, the spot setting unit 202b may determine that a visit has been made to the POI when the current position is continuously present around the POI or in the POI area for a predetermined number of times or more. In addition, the point setting unit 202b may determine a visit to the POI using the determination methods (2) and (3) described above. In addition, the location setting unit 202b selects a POI whose number of visits of POI is equal to or greater than a predetermined number of times or a visit frequency calculated based on the number of visits based on position information (history of current position information, etc.). May be. For example, a POI that visits at a certain number of visits or visits with a visit frequency greater than or equal to a predetermined value may be selected, and the type or attribute that satisfies the conditions specified by the user (user POI of a facility or a store category that suits the user's preference) may be selected. Further, the spot setting unit 202b may set two spots that are a starting point and an ending point defined by the spot information. For example, the spot setting unit 202b may set two POIs of the type or attribute that satisfy the conditions set by the user corresponding to the starting point and the ending point specified by the spot information as the two spots.

  Then, the route setting unit 202f of the server device 200 sets a route between two points (two POIs) set by the point setting unit 202b based on the road information stored in the road database 206a (step SA- 5). Here, the route setting unit 202f may set a route between two points based on the road information stored in the road database 206a and the history of the current position information stored in the position database 206b. The route setting unit 202f may search for a route between two points based on road network data of road information stored in the road database 206a. In addition, the route setting unit 202f transmits control data that allows the user to designate a route between two points to the terminal device 100 based on the road map data of the road information stored in the road database 206a. Between the two points designated by the user based on the designation information received from the terminal device 100 by receiving the designation information (for example, the information specifying the waypoint on the map) input via the input unit 116 May be set. Here, when two points are set by the point setting unit 202b based on the history of the current position information, the route setting unit 202f sets a waypoint based on the history of the current position information and searches for a route. May be performed. On the other hand, the route setting unit 202f, when two points are set by the point setting unit 202b based on the point information (because there is no travel history), road information such as road network data stored in the road database 206a. The route may be set based on The route setting unit 202f may allow the user to change the route set based on the current position information history (travel history) or the road information, or the processing based on the travel history and the route search are performed in parallel. The route may be set by arbitrarily combining these processes such as searching for an optimum route.

  Then, the section information acquisition unit 202g of the server device 200 includes at least one of the distance of the route and the undulation status (level difference or the like) together with the identification information of the route between the two points set by the route setting unit 202f. Information is acquired and stored in the section database 206c (step SA-6). Here, the section information acquisition unit 202g may acquire distance or undulation information from the road information in the road database 206a. When the route search by the route setting unit 202f is executed, If there is undulation information, it may be used. The section information acquisition unit 202g may store the section information for each user in the section database 206c using the user identification information or the like.

  The above is the section information acquisition process for storing the section information in the section database 206c. Next, a guide information providing process for providing guide information using the section information stored in the section database 206c will be described below.

  As illustrated in FIG. 3, the guidance route condition transmission unit 102c of the terminal device 100 transmits a guidance route condition including at least a departure place and a destination to the server device 200 (step SA-7). Here, the guide route condition transmitting unit 102c may control the user to input the guide route condition via the input unit 116, and may transmit the guide route condition input by the user to the server device 200. Further, the guidance route condition transmission unit 102c may set the current location based on the current location information acquired by the location information acquisition unit 102a as the departure location as the guidance route condition. Further, the guidance route condition acquired by the guidance route condition transmission unit 102c may further include a departure time or an arrival time, and the departure time is the current time acquired by the internal clock of the control unit 102. May be. Further, the guide route condition may further include a transit point and a transit time.

  Then, the guide route condition receiving unit 202h of the server device 200 receives the guide route condition including the departure place and the destination transmitted from the terminal device 100 (step SA-8). The guide route condition receiving unit 202h may receive the user identification information transmitted together with the guide route condition from the terminal device 100, or may acquire the user identification information by analyzing the communication route of the network 300 or the like. Good.

  Then, the guidance route setting unit 202i of the server device 200 guides from the departure point to the destination that satisfies the guidance route condition received by the guidance route condition reception unit 202h based on the road information stored in the road database 206a. A route is set (step SA-9). For example, the guidance route setting unit 202i may search for the optimum route such as the shortest route or the shortest time route from the departure point to the destination based on the road network data of the road information stored in the road database 206a. Here, the guide route searched by the guide route setting unit 202i may be, for example, a combination of road links indicating the route, and obtains an optimal guide route based on the link cost of the road link indicating the route. May be. In addition, the guide route setting unit 202i transmits control data that allows the user to designate or change the guide route to the terminal device 100 based on the road map data of the road information stored in the road database 206a. The designation information input via the input unit 116 via the input unit 116 (for example, information specifying the waypoint on the map) is received from the terminal device 100, and the guidance route specified by the user based on the specification information is received. It may be set.

  Then, the section information search unit 202j of the server device 200 has at least one of the predetermined section, distance, and undulation status of the guide route set by the guide route setting unit 202i from the section information stored in the section database 206c. Section information that is the same or approximate is searched (step SA-10). When the user identification information of the user of the terminal device 100 that has received the guide route condition is obtained, the section information search unit 202j displays the section information of the user corresponding to the user identification information in the section database. You may search from 206c. Here, the predetermined section of the guidance route set by the section information search unit 202j is a section where provision of section information as a guideline is considered necessary. For example, the section information search unit 202j guides based on the moving means. A predetermined section of the route may be set, or the predetermined section may be set based on the history of the current position information, the section information, or the route specified by the user. Moreover, the section information search part 202j may search the next section information close | similar outside the said same or approximate range, when the same or approximate section information cannot be searched. In this case, the section information search unit 202j displays “n times” or “n times” of a predetermined section in order to present guideline information such as “corresponding to the distance (= 2 times) from home to OO station”. Section information such as “1 / n” may be searched. In addition, the section information search unit 202j may search for section information by prioritizing a distance (nearest one), the number of travels (one that is frequently traveled), a travel date and time (new ones), Further, the search may be performed by comprehensively judging these by weighting or the like.

  Then, the guide information transmitting unit 202k of the server device 200 transmits guide information including the guide route associated with the section information searched by the section information searching unit 202j to the terminal device 100 (which has transmitted the guide route condition). (Step SA-11).

  Then, the guide information receiving unit 102d of the terminal device 100 receives the guide information transmitted from the server device 200 (step SA-12). Here, the guide information receiving unit 102d may store the received guide information in the storage unit 106.

  Then, the guide information output unit 102e of the terminal device 100 outputs a guidance route in association with the section information to the output unit 114 based on the guide information received by the guide information receiving unit 102d (step SA-13). . For example, the guide information output unit 102e may perform display output, audio output, or the like on the output unit 114 by comparing distances or undulations between the section information and the guide route based on the guide information.

  The above is the basic processing of the navigation system.

[Implementation process]
Next, an example of a concrete process of the navigation system in the first embodiment will be described in detail with reference to FIGS. 4 to 11 below. In this embodiment, the section information acquisition process is performed on the assumption that the section information is acquired based on the current position information history (running history), and the guidance searched by the server device 200 based on the guide route condition. A detailed process of the guide information providing process when a guide request is received from the terminal device 100 regarding the route will be described. Here, FIG. 4 is a flowchart showing an example of the section information acquisition process in the materialization process of the navigation system. FIG. 5 is a flowchart showing an example of guide information provision processing in the materialization processing of the navigation system.

  As shown in FIG. 4, first, the location information acquisition unit 102 a of the terminal device 100 acquires the current location information of the terminal device 100 based on the location information signal received from the location transmission device 500 by the location acquisition unit 112. (Step SB-1). Here, the position information acquisition unit 102a may acquire the current position information of the terminal device 100 every predetermined time (predetermined period) (for example, every second or every 3 minutes).

  Then, the location information transmission unit 102b of the terminal device 100 transmits the current location information acquired by the location information acquisition unit 102a to the server device 200 (step SB-2). Here, the position information transmission unit 102b may transmit the current position information every time the current position information is updated by the position information acquisition unit 102a, or collects the history of the current position information updated within a certain period. May be transmitted to the server device 200.

  Then, the location information receiving unit 202a of the server device 200 receives the current location information transmitted from the terminal device 100 (step SB-3). Here, the position information receiving unit 202a receives the user identification information transmitted together with the current position information from the terminal device 100, and stores the history of the current position information in the position database 206b in association with the user identification information. May be.

  Then, the location information receiving unit 202a of the server device 200 accumulates the history of the current location information updated by being transmitted from the terminal device 100 as the travel history in the location database 206b (step SB-4).

  Then, the point setting unit 202b of the server device 200 extracts candidate POIs from the road database 206a based on the history of the current position information stored in the position database 206b by the processing of the POI extraction unit 202c (step SB- 5). For example, the POI extraction unit 202c may extract candidate POIs according to preset extraction conditions. For example, the POI extraction unit 202c determines that the position information is within a predetermined distance range, the position information history is continuously present around the POI or in the POI area for a predetermined number of times, Even if the candidate POI is extracted according to the extraction conditions such as the number of visits based on the history of information being more than a certain number or the visit frequency being more than a certain frequency, the type and attributes (facility category that suits the user's preference, etc.) Good. The POI designation unit 202e receives the designation information input by the user via the input unit 116 by transmitting control data that allows the user to specify the extraction condition to the terminal device 100, and receives the received designation. Based on the information, an extraction condition used for the POI extraction unit 202c may be set.

  Then, the point setting unit 202b of the server device 200 selects two POIs that are both ends of the section of the section information from the candidate POIs extracted by the POI extraction unit 202c by the processing of the POI selection unit 202d (Step SB- 6). For example, when four candidate POIs of point A (departure point), point B (route point 1), point C (route point 2), point D (destination) are extracted by the above-described POI extraction unit 202c, The POI selection unit 202d selects a maximum of six sections of AB, AC, AD, BC, BD, and CD. The POI selection unit 202d is not limited to selecting all combinations of POIs, but may select some combinations according to preset selection conditions and the like. For example, in the case of the above-described example, when a selection condition for excluding a transit point is set, the POI selection unit 202d selects two POIs, a point A (departure point) and a point D (destination). The POI designation unit 202e receives the designation information input by the user via the input unit 116 by transmitting control data that allows the user to specify the selection condition to the terminal device 100, and receives the received designation. Based on the information, a selection condition used for the POI selection unit 202d may be set.

  Then, the route setting unit 202f of the server device 200 selects the section selected by the point setting unit 202b based on the road information stored in the road database 206a and the history of the current position information stored in the position database 206b. A path between two POIs at both ends is set (step SB-7). For example, the route setting unit 202f may search for a route between two POIs based on the road network data stored in the road database 206a. At this time, the route setting unit 202f may display a history of current position information (travel history) ) May be taken into consideration. For example, when searching for a route between two POIs based on road network data, the route setting unit 202f may set a waypoint based on the history of current position information in the guide route condition, and a plurality of route search results A route that does not have a travel history may be excluded from the route.

  Then, the section information acquisition unit 202g of the server device 200 includes section information including at least one of the distance of the route and the undulation status (level difference or the like) together with the identification information of the route between the 2POIs set by the route setting unit 202f. Is stored in the section database 206c (step SB-8). The section information acquisition unit 202g may store the section information for each user in the section database 206c using the user identification information received by the position information receiving unit 202a.

As described above, the server device 200 collects section information that serves as a guide based on the travel history. Next, a specific process of the guide request process will be described below with reference to FIG. In the present embodiment, when receiving the guide route condition, the server device 200 first transmits information on only the guide route for which the route search has been performed to the terminal device 100, waits for a guide request from the terminal device 100, Provide guideline information.

  As illustrated in FIG. 5, the guidance route condition transmission unit 102c of the terminal device 100 sets a guidance route condition including at least a departure place and a destination (step SB-9). For example, the guidance route condition transmission unit 102c may control the user to input the guidance route condition via the input unit 116. In addition, the guide route condition transmission unit 102c may set the current position based on the current position information acquired by the position information acquisition unit 102a as the departure point of the guide route condition.

  Then, the guide route condition transmitting unit 102c of the terminal device 100 transmits the set guide route condition to the server device 200 (step SB-10), and the guide route condition receiving unit 202h of the server device 200 transmits from the terminal device 100. The guide route condition including the departure point and the destination is received (step SB-11).

  Then, the guidance route setting unit 202i of the server device 200 guides from the departure point to the destination that satisfies the guidance route condition received by the guidance route condition reception unit 202h based on the road information stored in the road database 206a. A route is set (step SB-12). For example, the guidance route setting unit 202i may search for the optimum route such as the shortest route or the shortest time route from the departure point to the destination based on the road network data of the road information stored in the road database 206a.

  And the guidance route setting part 202i of the server apparatus 200 transmits the guidance route information containing the set guidance route to the terminal device 100 (step SB-13). Here, the guide route information transmitted by the guide route setting unit 202i may be information including a display screen for allowing the user to specify a section for which the guide information is requested. FIG. 6 is a diagram illustrating an example of a display screen based on the guidance route information. As shown in FIG. 6, as an example, the display screen based on the guide route information includes a guide route display screen MB-1 that displays a guide route condition that satisfies the guide route condition from the home to the TT tower, and a section information search unit 202j. It includes a guide request button MB-2 to be installed and used for requesting a guide.

  As shown in FIG. 6, the guidance route shown on the guidance route display screen MB-1 is the walking section from the home to the XX ward office, the train section from the XX ward office to the WW gate, and the WW gate to the TT tower. Includes a walking section. Here, the section information search unit 202j selects a guide request button MB for sections that are considered unnecessary to provide section information other than sections that need to provide section information that serves as a guide among the set guidance routes. -2 etc. may be excluded. For example, the section information search unit 202j may exclude a predetermined section of the guidance route based on the moving unit. That is, as in the example of FIG. 6 described above, when the walking route includes a walking section and a train section, the section information search unit 202j does not need to obtain a guideline such as a distance between train sections. The guide request button MB-2 is set for the walking section, excluding the train section. The section information search unit 202j may exclude a predetermined section based on the history of current position information, section information, or a route specified by the user. As an example, the section information search unit 202j may exclude a section in which a history of current position information stored in the position database 206b exists (for example, a section in which a history of traveling a predetermined number of times or more remains). Further, the section based on the section information stored in the section database 206c is the section set by the section information search unit 202j based on the current position information history (running history) or point information designated by the user. Installation of a guide request button or the like may be excluded because provision of a guide is unnecessary. The section information search unit 202j is a route that is set by the user as a guideline for the route specified by the user under the control of the route setting unit 202f. May be excluded. In the example of FIG. 6, the reference request button MB-2 is associated with the section from the WW gate to the TT tower in advance, but in this example, the section from the home to the XX ward office is also a walking section. However, since the section from the home to the nearest station is a section where provision of a guide is considered unnecessary, the guide request button MB-2 is not installed.

  And the control part 102 of the terminal device 100 receives guidance route information (step SB-14), and outputs a guidance route to the output part 114 based on the received guidance route information (step SB-15).

  Then, the control unit 102 of the terminal device 100 controls the user to select whether or not to send a guide request for providing guide information via the input unit 116, and when the guide request is selected, the guide request is selected. The request is transmitted to the server device 200 (step SB-16). For example, in the example of FIG. 6, when the user clicks the guide request button MB-2 via the input unit 116, the guide request transmission is determined. In step SB-16 described above, the user may transmit a guide request by designating a predetermined section. The terminal device 100 transmits a guide request specifying a section from the WW gate to the TT tower.

  Then, when the section information search unit 202j of the server device 200 receives the guide request transmitted from the terminal device 100 (step SB-17), the section information search unit 202j uses the guide request among the guide routes set by the guide route setting unit 202i. The designated predetermined section is set (step SB-18).

  Then, the section information search unit 202j of the server device 200 searches the section database 206c for section information that is the same as or approximate to the set predetermined section and the distance and / or undulation status (step SB-19). Note that the section information search unit 202j may search for the next section information that is close outside the same or approximate range when the same or approximate section information cannot be searched.

  Then, when the guide information transmitting unit 202k of the server device 200 transmits guide information including the section information searched by the section information searching unit 202j to the terminal device 100 (step SB-20), the guide information receiving of the terminal device 100 is received. The unit 102d receives the guide information transmitted from the server device 200 (step SB-21).

  Then, the guide information output unit 102e of the terminal device 100 displays a guide route in association with the section information on the output unit 114 based on the guide information received by the guide information receiving unit 102d (step SB-22). . For example, the guide information output unit 102e may perform display output, audio output, or the like on the output unit 114 by comparing distances or undulations between the section information and the guide route based on the guide information. Here, FIGS. 7 to 11 are diagrams illustrating examples of display screens displayed by the guide information output unit 102e based on the guide information. As an example, as shown in FIG. 7, the guide information output unit 102e is based on the section information based on the travel history at the same distance as the predetermined section of the guide route indicated by the guide information, “WW gate → TT tower (about 0.8km) is about the same as the distance from A to B that you walked on 12/31 ", etc." It may be output. Further, as shown in FIG. 8, the guide information output unit 102e is based on section information based on a point route (My route or the like) designated by the user at the same distance as the predetermined section of the guide route indicated by the guide information. Then, output the text data and voice data such as “WW Gate → TT Tower (about 0.8km) ... the same distance from your home to the supermarket” via the output unit 114. Also good. Further, as shown in FIG. 9, the guide information output unit 102e is based on the next section information that is the same as or close to the predetermined section indicated by the guide information, and “A → B is 0. Text data or the like such as “5 km A → C is 1 km” may be output so that the user can compare. In addition, it is not restricted to displaying text data, You may display so that a predetermined section on a guidance route and the section of section information can be compared with a route on a graph or a map. For example, as shown in FIG. 10, the guide information output unit 102e can visually compare the difference in distance between a predetermined section of the guide route and a section (A → B) of the section information based on the guide information. It may be expressed. Further, as shown in FIG. 11, the guide information output unit 102e compares the difference in undulation between the predetermined section of the guide route and the section of the section information (A → B) in addition to the distance based on the guide information. It may be expressed by a height difference or the like so that it can be done.

Here, the display screen generation unit 202n may generate a display screen that compares the distance or the undulation state between the section information and a predetermined section of the guide route. As an example, the display screen generation unit 202n searches for a predetermined section of the guidance route based on section information whose distance, undulation status, etc. are the same or approximate, as a result of the search. It is also possible to generate a display screen that displays the text “It is about the same as the distance from point B to point B”. Further, the display screen generating unit 202n determines that the “A point” is selected when the section information searched by the section information searching unit 202j is section information of a section that is not the same as or approximate to the predetermined section of the guidance route but is close to the next point. It is possible to generate a display screen that displays text such as “Xkm from your home to point B. By the way, from your home to the supermarket is Ykm.” In addition, it is not limited to generating a display screen that displays text data, and a display screen that is compared with a route on a graph or a map is generated so that a predetermined section on the guidance route can be compared with a section of section information. Also good.

The navigation device 400 may be, for example, various navigation terminals such as a PND (Portable Navigation Device), various information processing devices such as a notebook personal computer, or a mobile terminal device such as a mobile phone, PHS, or PDA. .

  In FIG. 14, the functions of the input / output control interface unit 408, the communication control interface unit 404, the position acquisition unit 412, the output unit 414, the input unit 416, the network 300, and the external device 600 are the first embodiment. Since it is the same as that, description is abbreviate | omitted. In addition, each function of the storage unit 406 (the road database 406a, the position database 406b, the section database 406c, and the like) is the first implementation except that the navigation device 400 is provided instead of the server device 200. Since it is the same as that of the form, the description is omitted.

  As for each part of the control unit 402, each function is basically the same as that of the first embodiment except that the navigation device 400 of the present embodiment is a stand-alone type and the control unit 402 does not include each transmission unit. The same as above.

  In FIG. 14, the control unit 402 includes an internal memory for storing a control program such as an OS, a program that defines various processing procedures, and necessary data. And the control part 402 performs the information processing for performing various processes with these programs. In terms of functional concept, the control unit 402 includes a position information acquisition unit 402a, a spot setting unit 402b, a route setting unit 402f, a section information acquisition unit 402g, a guide route condition acquisition unit 402h, a guide route setting unit 402i, and a section information search unit 402j. , And a guide information output unit 402k.

  Among these, the position information acquisition unit 402a is position information acquisition means for acquiring position information such as current position information and point information. Here, the position information acquisition unit 402a may acquire the current position information of the user of the navigation device 400 based on the position information signal transmitted from the position transmission device 500. In addition, the position information acquisition unit 402a controls the user to input two points serving as a starting point and an end point such as position coordinates via the input unit 416, and acquires point information that defines the two points. May be.

  The point setting unit 402b is a point setting unit that sets two points based on position information (history of current position information or point information) acquired by the position information acquisition unit 402a and stored in the position database 406b. . Here, the point setting unit 402b may select two POIs as two points from the POI information of the road information based on the history of the current position information. Here, the location setting unit 402b may select the visited POI as a location based on the history of the current position information, as in the examples (1) to (3) described above. For example, as described in (1) above, the location setting unit 402b visits the POI when the current location based on the history of the current location information exists continuously in the POI area or in the POI area for a predetermined number of times or more. You may determine that you did. As described above, the point setting unit 402b determines a visit based on the history of the current location information, and selects a POI whose number of POI visits is a predetermined number or more or whose visit frequency calculated based on the number of visits is a predetermined value or more. May be. Further, the spot setting unit 402b may select a POI of a type or attribute that satisfies a condition set by the user. For example, the point setting unit 402b may set two points serving as a starting point and an ending point defined by the point information, and the type or attribute 2 that satisfies the conditions set by the user corresponding to the starting point and the ending point. One POI may be set as two points. Here, as shown in FIG. 14, the spot setting unit 402b may include a POI extraction unit 402c, a POI selection unit 402d, and a POI designation unit 402e.

  Among these, the POI extraction unit 402c is a POI extraction unit that extracts candidate POIs from the road database 406a based on the position information stored in the position database 406b. The POI extraction condition extracted by the POI extraction unit 402c is within a predetermined distance range from the position indicated by the position information, and the history of the position information exists continuously for a predetermined number of times around the POI or in the POI area. Staying for more than a certain period of time, location information history is more than a certain number of visits or more than a certain number of visits, it is a place where users often visit, and the type and attributes of POI are set May be.

  The POI selection unit 402d is a POI selection unit that selects two POIs at both ends of the section of the section information from the POIs extracted by the POI extraction unit 402c. For example, when four POIs of point A (departure point), point B (route 1), point C (route 2), and point D (destination) are extracted by the POI extraction unit 402c, the POI The selection unit 402d can select a maximum of six sections, but selects the section AD between the departure point (point A) and the destination (point D) as the section information section, The section (for example, section BC) is unnecessary as a section of the section information and may not be selected. That is, since the POI extraction unit 402c automatically acquires all the routes, the two POIs may be automatically selected so as to be a combination of all points, and only some of these routes are selected. In order to obtain the two POIs, two POIs may be selected according to a selection condition (for example, a combination condition at both ends such as a departure point and a destination other than a waypoint).

  The POI designating unit 402e is a POI designating unit that accepts user designation in POI extraction or selection. For example, the POI designation unit 402e controls the user to input the extraction condition or selection condition described above, or the POI to be extracted or the POI to be selected, to the user via the input unit 416. Based on the input designation information, The extraction condition, selection condition, POI, etc. used in the POI extraction unit 402c or POI selection unit 402d are set. As a specification mode by the user, the POI extracted or selected by the POI extraction unit 402c or the POI selection unit 402d may be determined by the user, or unnecessary combinations may be excluded. In the above example, the example in which the extraction process by the POI extraction unit 402c and the selection process by the POI selection unit 402d are performed separately has been described. However, the present invention is not limited to this, and the point setting unit 402b integrates these processes. May be performed. For example, the spot setting unit 402b may perform the integration process using an integration condition obtained by integrating the extraction condition and the selection condition described above.

  The route setting unit 402f is route setting means for setting a route between two points (two POIs) set by the point setting unit 402b based on road information stored in the road database 406a. Here, the route setting unit 402f may set a route between two points based on the road information stored in the road database 406a and the history of the current position information stored in the position database 406b. In addition, the route setting unit 402f may search for a route between two points based on road network data of road information stored in the road database 406a. If an optimum route can be set by route search, an objective route that is easy for anyone to understand can be set. Further, the route setting unit 402f controls the user to specify the route between the two points via the input unit 416 based on the road map data of the road information stored in the road database 406a. The route designated by the user may be set based on the designation information input via the unit 416 (for example, information specifying the waypoint on the map). Here, when two points are set by the point setting unit 402b based on the history of the current position information, the route setting unit 402f sets a waypoint based on the history of the current position information and searches for a route. May be performed. On the other hand, when two points are set by the point setting unit 402b based on the point information, the route setting unit 402f determines the route based on the road information stored in the road database 406a (since there is no travel history). It may be set. The user may be able to change the route set based on the current position information history (travel history) or road information, or the optimum route can be determined by performing processing based on the travel history and route search in parallel. For example, the route setting unit 402f may set a route by arbitrarily combining these processes.

  Further, the section information acquisition unit 402g acquires section information including at least one of the distance of the route and the undulation status (e.g. height difference) together with the identification information of the route between the two points set by the route setting unit 402f. Section information acquisition means stored in the section database 406c. Here, the section information acquisition unit 402g may acquire distance or undulation information from road information in the road database 406a. The section information acquisition unit 402g may store the section information for each user in the section database 406c using the user identification information or the like.

  The guidance route condition acquisition unit 402h is a guidance route condition acquisition unit that acquires a guidance route condition including a departure place and a destination. For example, the guide route condition acquisition unit 402h may control the user to input the guide route condition via the input unit 416. Further, the guidance route condition acquisition unit 402h may set the current position based on the current position information acquired by the position information acquisition unit 402a as a departure point. The guide route condition may further include a departure time or an arrival time. Here, the departure time may be the current time. Further, the guide route condition may further include a transit point and a transit time.

  The guide route setting unit 402i sets a guide route from the departure point to the destination that satisfies the guide route condition acquired by the guide route condition acquiring unit 402h based on the road information stored in the road database 406a. It is a guidance route setting means. Here, the guide route searched by the guide route setting unit 402i may be, for example, a combination of road links indicating the route, and an optimum guide route is acquired based on the link cost of the road link indicating the route. May be. For example, the guidance route setting unit 402i may search for an optimum route such as a shortest route or a shortest time route from the departure point to the destination based on road network data of road information stored in the road database 406a. Further, the guide route setting unit 402i controls the user to designate or change the guide route via the input unit 416 based on the road map data of the road information stored in the road database 406a, and is input by the user. A guidance route designated by the user may be set based on designation information input via the unit 416 (for example, information indicating a waypoint on the map).

  In addition, the section information search unit 402j selects the predetermined section of the guide route set by the guide route setting unit 402i, the distance, and the undulation status from the section information acquired by the section information acquisition unit 402g and stored in the section database 406c. Section information search means for searching for section information in which at least one of them is the same or approximate. Here, a threshold value that defines a range that is the same or approximate may be provided (for example, a predetermined distance in the case of a distance, a predetermined height difference in the case of undulations, or the like). The section information search unit 402j may search for section information that is close outside the same or approximate range when the same or approximate section information cannot be searched. Thereby, even if there is no section information that is the same or approximate, section information of a section that serves as a reference can be provided, so that the user can grasp a rough sense of perspective. The section information search unit 402j may search the section information by prioritizing the distance (closest one), the number of times of travel (those that are frequently traveled), the travel date and time (new ones), The search may be performed by comprehensively judging these by weighting or the like. Further, the section information search unit 402j may set a predetermined section of the guide route set by the guide route setting unit 402i based on the moving unit. As an example, when the guide route set by the guide route setting unit 402i includes a walking section and a section using public transportation, the section information search unit 402j determines the public transportation based on the moving means. The section to be used may be excluded, and a walking section may be set as a predetermined section to be searched. In addition, the section information search unit 402j selects a predetermined section of the guide route set by the guide route setting unit 402i, the current position information history stored in the position database 406b, the section information stored in the section database 406c, Or you may set based on the path | route designated by the user by control of the path | route setting part 402f. The section information search unit 402j controls the user to specify or change a predetermined section via the input unit 416, and specifies information (for example, predetermined on the map) input by the user via the input unit 416. The section designated by the user may be set based on the information specifying the both ends of the section.

[Processing of navigation device 400 (stand-alone type)]
Next, an example of the process of the navigation device 400 according to the third embodiment configured as described above will be described in detail with reference to FIG.

  As shown in FIG. 15, first, the position information acquisition unit 402a acquires position information such as current position information and point information (step SD-1). For example, the location information acquisition unit 402a may control the user to input point information via the input unit 416, and the location information acquisition unit 402a may calculate the current information calculated from the location information signal received from the location transmission device 500 by the location acquisition unit 412. You may acquire position information. As an example, the position information acquisition unit 402a may acquire point information such as position coordinates input by the user via the input unit 416. For example, the position information acquisition unit 402a allows the user to specify on the display screen based on the map information displayed on the output unit 414 via the input unit 416 (for example, a specifying operation on the touch panel type output unit 414). The coordinates may be acquired as point information. In addition, the position information acquisition unit 402a does not acquire position information regarding two points serving as a starting point and an end point, but instead acquires point information regarding a route (such as a voice guidance actual route) between the two points (for example, a user). The reference route from the home designated to the nearest station) may be acquired.

  Then, the point setting unit 402b sets two points based on the position information acquired by the position information acquisition unit 402a (current position information history or point information) (step SD-2). For example, the spot setting unit 402b may set two spots that are a starting point and an ending point defined by the spot information. Here, the point setting unit 402b may set two POIs as two points from the POI information of the road information based on the position information. Further, the spot setting unit 402b may set the visited POI as a spot based on the position information. For example, it may be determined that a visit has been made to the POI when the current position is continuously present around the POI or within the POI area for a predetermined number of times. In addition, the location setting unit 402b may select a POI whose number of POI visits is a certain number of times or a visit frequency calculated based on the number of visits based on the position information, and is designated by the user. A POI of a type or an attribute (such as a category such as a facility or a store that meets the user's preference) that satisfies the specified conditions may be selected. In addition, the spot setting unit 402b may set two POIs of a type or attribute that satisfy the conditions set by the user corresponding to the starting point and the ending point specified by the spot information as two spots.

  Then, the route setting unit 402f sets a route between two points (two POIs) set by the point setting unit 402b based on the road information stored in the road database 406a (step SD-3). Here, the route setting unit 402f may set a route between two points based on the road information stored in the road database 406a and the history of the current position information stored in the position database 406b. In addition, the route setting unit 402f may search for a route between two points based on road network data of road information stored in the road database 406a. Further, the route setting unit 402f controls the user to specify the route between the two points via the input unit 416 based on the road map data of the road information stored in the road database 406a. A route between two points designated by the user may be set based on designation information input via the unit 416 (for example, information indicating a waypoint on the map). Here, when two points are set by the point setting unit 402b based on the history of the current position information, the route setting unit 402f sets a waypoint based on the history of the current position information and searches for a route. May be performed. On the other hand, the route setting unit 402f, when two points are set by the point setting unit 402b based on the point information (because there is no travel history), road information such as road network data stored in the road database 406a. The route may be set based on The route setting unit 402f may allow the user to change the route set based on the current position information history (travel history) or the road information, or the processing based on the travel history and the route search are performed in parallel. The route may be set by arbitrarily combining these processes, such as searching for an optimal route.

  Then, the section information acquisition unit 402g acquires section information including at least one of the distance of the route and the undulation status (e.g. height difference) together with the identification information of the route between the two points set by the route setting unit 402f. And stored in the section database 406c (step SD-4). Here, the section information acquisition unit 402g may acquire distance or undulation information from the road information in the road database 406a. When the route search by the route setting unit 402f is performed, If there is undulation information, it may be used. The section information acquisition unit 402g may store the section information for each user in the section database 406c using the user identification information or the like.

  Subsequently, the guidance route condition acquisition unit 402h acquires a guidance route condition including at least a departure place and a destination (step SD-5). For example, the guide route condition acquisition unit 402h may control the user to input the guide route condition via the input unit 416, and may acquire the guide route condition input by the user. In addition, the guidance route condition acquisition unit 402h may set the current location based on the current location information acquired by the location information acquisition unit 402a as the departure location as the guidance route condition. Further, the guidance route condition acquired by the guidance route condition acquisition unit 402h may further include a departure time or an arrival time, and the departure time is the current time acquired by the internal clock of the control unit 402. May be. Further, the guide route condition may further include a transit point and a transit time.

  Then, the guide route setting unit 402i sets a guide route from the departure point to the destination that satisfies the guide route condition acquired by the guide route condition acquiring unit 402h based on the road information stored in the road database 406a. (Step SD-6). For example, the guidance route setting unit 402i may search for an optimum route such as a shortest route or a shortest time route from the departure point to the destination based on road network data of road information stored in the road database 406a. Here, the guide route searched by the guide route setting unit 402i may be, for example, a combination of road links indicating the route, and an optimum guide route is acquired based on the link cost of the road link indicating the route. May be. Further, the guide route setting unit 402i controls the user to specify or change the guide route via the input unit 416 based on the road map data of the road information stored in the road database 406a, and is input by the user. A guidance route designated by the user may be set based on designation information input via the unit 416 (for example, information indicating a waypoint on the map).

  Then, the section information search unit 402j has the same or approximate at least one of the predetermined section of the guide route set by the guide route setting unit 402i, the distance, and the undulation state from the section information stored in the section database 406c. Some section information is searched (step SD-7). Here, the predetermined section of the guidance route set by the section information search unit 402j is a section where provision of section information that serves as a guideline is necessary. For example, the section information search unit 402j guides based on the moving means. A predetermined section of the route may be set, or the predetermined section may be set based on the history of the current position information, the section information, or the route specified by the user. Moreover, the section information search part 402j may search the next section information of the near point outside the same or approximate range, when the same or approximate section information cannot be searched. In addition, the section information search unit 402j may search for section information by prioritizing a distance (the closest one), the number of times of travel (a thing that is frequently traveled), a travel date and time (a new one), Further, the search may be performed by comprehensively judging these by weighting or the like.

  Then, the guide information output unit 402k outputs a guide route in association with the section information to the output unit 414 based on guide information including the guide route in which the section information searched by the section information search unit 402j is associated. (Step SD-8). For example, the guide information output unit 402k may perform display output, audio output, or the like on the output unit 414 by comparing the distance or the undulation state between the section information and the guide route based on the guide information.
