  Here, the map information as the information includes, for example, display data VM which is so-called POI (Point Of Interest) data as shown in FIG. 2, matching data MM as shown in FIG. Data and so on.

  The display data VM includes, for example, a plurality of display mesh information VMx each having a unique number added thereto. That is, the display data VM is divided into a plurality of pieces of display mesh information VMx relating to a part of the region, and a plurality of pieces of display mesh information VMx are continuously arranged in the vertical and horizontal directions. Note that the display mesh information VMx may be further divided into a plurality of lower display mesh information VMx for a part of the area as appropriate. Each display mesh information VMx is divided into a rectangular shape with the length of one side set, that is, the actual topographical length shortened according to the scale of the map, and the map information is displayed at predetermined corners. It has information on absolute coordinates ZP on the whole, for example, the map of the earth.

  The display mesh information VMx includes, for example, name information VMxA such as an intersection name, road information VMxB, and background information VMxC. The name information VMxA has a table structure of data in which other element data in the area, for example, the name of an intersection, the name of an area, and the like are arranged and displayed at a predetermined position in a positional relationship with the absolute coordinate ZP. The road information VMxB is configured in a data table structure in which a road, which is road element data in the region, is arranged and displayed at a predetermined position in a positional relationship with the absolute coordinate ZP. In the background information VMxC, a mark indicating a famous place or building that is other element data, or image information that is other element data indicating the famous place or building, etc. is determined in a positional relationship with the absolute coordinate ZP. It is structured in a table structure of data arranged and displayed at positions.

Has been. Note that the display mesh information MMx may be further divided into a plurality of lower-layer matching mesh information MMx regarding a part of the region as appropriate. Each matching mesh information MMx is divided into a rectangular shape with the length of one side set, that is, the length on the actual terrain shortened according to the scale of the map, and the entire map information is divided into predetermined corners. For example, it has information on absolute coordinates ZP on a map of the earth. Note that the matching mesh information MMx may have a different data structure representing an area different from the display mesh information VMx, that is, the scale of the divided area may be different. Here, if the scales are the same, the data may be associated using information of a unique number, and if the scales are different, the data may be associated using absolute coordinates, for example.

  The matching data MM represents the vehicle in order to prevent erroneous display such as when the display representing the vehicle is located on the building instead of on the road when the moving state of the vehicle is superimposed on the map information. This is used for map matching processing for correcting the display so that the display is positioned on the road. This matching data MM has a plurality of link string block information.

  As shown in FIG. 3, in the link string block information, a plurality of links L as line segment information, which is a line segment connecting the nodes N as the point information constituting the road and representing the points, are associated with a predetermined regularity. It is a table structure of data. More specifically, the links L are associated with each other as a continuous link row that is continuous on a broken line, such as a continuous road such as a Koshu highway or an Ome highway. The link L is line information unique to each link L (hereinafter referred to as a link ID) and node information such as a unique number representing two nodes N connected by the link L. And have. The link L is associated with the VICS link, and the positional relationship between the VICS data and the map display corresponds to the link L.

  On the other hand, the node N corresponds to a nodal point such as an intersection, a bending point, a branch point, or a junction point of each road. The information related to the node N includes a plurality of point-specific information that is a unique number added to each node N in the link string block information, coordinate information of a position where each node N exists, and intersections and branch points. Flag information which is branch information indicating whether or not the link is a branch position where the link intersects. Note that the node N has only point-specific information and coordinate information that does not have flag information in order to simply represent the shape of the road, and attribute information that is information representing the configuration of the road such as a tunnel or the width of the road. Some have further added. A node N that does not have flag information and simply represents the shape of the road is not used for determining the identity of a point by the coordinate matching means 187 described later.

  Further, the travel route search map information has, for example, the same table structure as the matching data MM, that is, point information representing points such as a node N representing roads and line segment information connecting points such as links L. The table structure is an information structure for representing a road in order to search for a movement route.

  The storage unit 160 stores search information for acquiring information on a predetermined point in the map information, for example. In other words, the search information includes various information such as the prefecture name, municipality name, district name, point name, etc., guidance, and various information related to the store as a point, which are areas that are sequentially subdivided on the map information. For example, the table structure has a tree structure in which item information is associated in a hierarchical manner.

  The memory 170 stores setting items input by the terminal input unit 130, music data, image data, and the like so as to be appropriately readable. The memory 170 also stores various programs developed on an OS (Operating System) that controls the operation of the entire navigation apparatus 100. As the memory 170, it is desirable to use a memory having a configuration in which memory is retained even when the power is suddenly turned off due to a power failure, for example, a CMOS (Complementary Metal-Oxide Semiconductor) memory. Note that the memory 170 may include a drive, a driver, and the like that are readable and stored in a recording medium such as an HD, a DVD, or an optical disk.

  The processing unit 180 is connected to various input / output ports (not shown) such as a VICS receiving port to which a VICS antenna is connected, a GPS receiving port to which a GPS receiving unit is connected, a sensor port to which various sensors are connected, and a terminal input unit 130 to be connected.

  The current position recognition unit 181 recognizes the current position of the vehicle. Specifically, a plurality of current pseudo positions of the vehicle are calculated based on the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110. Further, the current position recognizing means 181 recognizes the current pseudo coordinate value of the vehicle based on the GPS data related to the current position output from the GPS receiver. Then, the current position recognizing means 181 compares the calculated current pseudo position with the recognized current pseudo coordinate value, calculates the current position of the vehicle on the separately acquired map information, and recognizes the current position. .

  Further, the current position recognizing means 181 judges the inclination and height difference of the road on the basis of the acceleration data output from the acceleration sensor, calculates the current pseudo position of the vehicle, and recognizes the current position. That is, it is possible to accurately recognize the current position of the vehicle even at places that overlap on a plane such as a three-dimensional intersection or an expressway. In addition, when traveling on mountain roads and hills, the current distance is obtained by correcting the error between the travel distance obtained from speed data and azimuth angle data and the actual vehicle travel distance using the detected road slope. Recognize position.

  Note that the current position recognizing unit 181 can recognize, as the current position, the starting point that is set and input by the terminal input unit 130 as the pseudo current position, in addition to the vehicle current position described above. Various types of information obtained by the current position recognition unit 181 are stored in the memory 170 as appropriate.

  The destination recognizing unit 182 acquires destination information related to the destination set and input by an input operation of the terminal input unit 130, for example, and recognizes the position of the destination. As the destination information, for example, various kinds of information for specifying a place such as coordinates such as latitude and longitude, an address, and a telephone number can be used. This destination information is appropriately stored in the memory 170.

  The specific location recognizing unit 183 acquires specific location information regarding the specific location set and input by an input operation of the terminal input unit 130, for example, and recognizes the location of the specific location. As this specific location, for example, various information for specifying a location such as coordinates such as latitude and longitude, an address, and a telephone number can be used. The specific position information is appropriately stored in the memory 170. Further, the specific location recognizing unit 183 includes feature information such as a store or a location selected by the input operation of the terminal input unit 130 from the specific location information stored in advance in the memory 170 or the search information stored in the storage unit 160. Can be acquired as specific position information.

  The guidance notifying means 184 is stored in the memory 170 and is based on the movement route information and feature guidance information acquired in advance corresponding to the traveling state of the vehicle, for example, guidance regarding the movement of the vehicle, for example, guidance for contents supporting the traveling of the vehicle. Are notified by the image display by the terminal display unit 140 and the pronunciation by the audio output unit 150. Specifically, a predetermined arrow or symbol is displayed on the display screen of the terminal display unit 140, or “700m ahead, the XX intersection is in the right direction in the △△ direction.”, “Departed from the moving route.” The voice output unit 150 may pronounce or make a sound such as “This is a traffic jam ahead”.

  The display control means 185 appropriately controls the terminal display unit 140 to display various information on the screen of the terminal display unit 140 and notify the user. Further, the display control means 185 is configured to display, for example, a guidance guidance screen 141 as shown in FIG. 5 or an overall guidance screen as a guidance screen as shown in FIG. 6 by a predetermined input operation of the terminal input unit 130 or recognition of various signals. 142 and a detailed guidance screen 143 as a guidance screen as shown in FIG. 7 are created, and are switched and displayed in one display area displayed on the terminal display unit 140. The guidance guidance screen 141, the overall guidance screen 142, and the detailed guidance screen 143 shown in FIGS. 5 to 7 exemplify the movement situation of the vehicle in a state where a predetermined movement route and a specific place are set. The display control means 185 is not limited to the control for switching and displaying the guidance guidance screen 141, the overall guidance screen 142, and the detailed guidance screen 143, and is appropriately combined into one display area by an input operation of the terminal input unit 130. You may control to display two screens or three screens for displaying all of them.

  Here, the guidance guidance screen 141 is screen information in which an icon 141A representing the current vehicle position, which is the current position, is superimposed on map information at a predetermined scale. The scale ratio in the guidance and guidance screen 141 is displayed on the terminal display unit 140 as a screen display based on, for example, a preset initial setting value, that is, a situation in which a driver or a passenger boarding the vehicle travels around the vehicle. It is a scale rate that can be recognized in contrast to the icon display that represents the road and features that are the contents. For example, in the case of mountain roads where there are no roads or road branches in the surroundings, a relatively small scale ratio may be used, and comparisons may be made if there are similar features or road conditions in the town. It is good also as a scale ratio with a large value. When a specific location is included at the scale ratio of the guidance guide screen 141, an icon 142A representing the specific location and a balloon-like balloon display 142B representing the content of the specific location are displayed in a superimposed manner. These icons 142A and balloon display 142B may not be displayed in a superimposed manner.

  In addition, the entire guidance screen 142 includes all of the specific locations described in the specific location information acquired by the specific location recognizing means 183, and has a maximum scale, that is, almost completely in the display area of the terminal display unit 140 that displays the map. This is screen information in which a specific place and an icon 142A are superimposed on map information of a scale ratio including all the specific places. Further, a balloon display 142B is superimposed and displayed on the entire guidance screen 142. Note that the entire guidance screen 142 is set to a scale ratio that includes all of the travel routes when the travel routes are set by the route processing means described later in detail. In addition, as the setting of the corresponding scale ratio, for example, the coordinates of the center point of the area including all the specific locations and the movement routes are calculated, and the scale ratio value is the most at the scale including all based on the center coordinates. Any method can be used, such as a configuration in which the map information is set by acquiring map information.

  Further, the detailed guidance screen 143 includes one of the specific locations closest to the current location among the specific locations described in the specific location information acquired by the specific location recognizing unit 183 and the current location and the scale ratio is This is image information in which an icon 142A indicating the specific location and the current position is superimposed with the content display 142B on the map information of the scale ratio that includes the specific location almost completely in the display area of the terminal display unit 140. The closest distance is, for example, the closest distance on the route on which the vehicle moves, or the closest distance in front of the vehicle traveling on the route, that is, the moving distance when moving to the specific location according to the guidance. Although the thing which makes it the shortest, and makes it the nearest distance from the current position of the vehicle in absolute distance can be exemplified, it is not limited to this. For example, “departure place” is selected if it is a specific place with the closest distance on the route (see FIG. 7), and “friend's house” is selected if it is the closest specific place in front of the vehicle on the route. Selected (not shown). The detailed guidance screen 143 is image information including different specific locations if the closest specific location is different when the current position is moved by the movement of the vehicle. Also, any method can be used for setting the scale ratio, as in the case of the overall guidance screen. 6 and FIG. 7, the icon 141A indicating the own vehicle position is displayed with the icon 142A indicating the specific place, but a dedicated icon 141A as shown in FIG. 5 may be superimposed and displayed.

  Furthermore, the display control means 185 also performs control such as changing the display area of the guidance display screen 141 by an input operation of the terminal input unit 130. The display area to be displayed on the entire guidance screen 142 and the detailed guidance screen 143 may be changed. The display control means 185 also controls display of various display screens for setting and inputting various information by prompting an input operation by the terminal input unit 130, for example.

  The map matching unit 186 performs map matching processing for appropriately displaying the current position recognized by the current position recognition unit 181 based on the map information acquired from the storage unit 160. As described above, the map matching unit 186 uses, for example, the matching data MM, and the position displayed by superimposing the current position on the map on the terminal display unit 140 constitutes the map displayed on the terminal display unit 140. A map matching process is performed in which the current position information is appropriately corrected, that is, corrected and displayed so as not to depart from the element road.

  The coordinate matching unit 187 performs a coordinate matching process that is a determination as to whether or not the point information that is the information about the node N of the matching data MM of the map information acquired from the storage unit 160 is the same point. That is, as described above, the point information of the node N of the matching data MM is acquired and the coordinate information constituting the point information is read. Specifically, coordinate values such as latitude and longitude are calculated based on coordinate value information and offset amounts of coordinate information, and if different nodes N have the same coordinate value, the point information of those nodes N is configured. The flag information to be read is read to determine whether or not the nodes N are the same point. When it is determined that the points are the same, for example, it is determined that the roads are connected to the node N and the links L constituting different link row block information intersect each other, for example, an intersection. If it is determined that the points are not the same point, for example, it is determined that the road L is connected to the node N, and the links L constituting different link row block information do not cross each other, for example, a three-dimensional intersection.

  The route processing unit 188 calculates a travel route of the vehicle based on the setting item information for route setting input by the user and the map information stored in the storage unit 160 to search for a route. For example, the route processing unit 188 may calculate the travel route based on VICS data or the like based on the setting item information, taking into account the current traffic jam situation and predicted traffic jam information. Specifically, the current position, destination, setting item information, current traffic jam information, and the like are acquired. Based on the acquired information, the map information for moving route search of the map information is used, for example, a road through which the vehicle can pass is searched, a route having a short required time, a route having a short moving distance, a traffic jam or the like Generate travel route information that sets routes that avoid traffic restrictions. Then, the required time to the destination on each route of the travel route information is obtained, and the required time information related to the required time is generated.

  In addition, when searching for this movement route, the map information matching data MM may be used in addition to the movement route search map information. For example, this is the case where a travel route is searched using a road that is not travel route search map information, such as a narrow road such as a back road. When the matching data MM is used, a route is appropriately searched based on the determination of the road state by the coordinate matching means 187. The travel route information also includes route guidance information that assists the travel by, for example, guiding the vehicle during travel. The route guidance information is appropriately displayed on the terminal display unit 140 or appropriately output as voice by the voice output unit 150 under the control of the guidance notification unit 184, and driving is assisted.

  The information search unit 189, for example, searches the search information stored in the storage unit 160 in a hierarchical manner based on item information or the like based on item information or the like in response to a search request for search information set and input by the terminal input unit 130. Search and get.

  The timer 190 recognizes the current time based on a reference pulse such as an internal clock. The time measuring means 190 can also measure the elapsed time from a predetermined time. And this time measuring means 190 outputs the time information regarding the recognized current time as appropriate.

FIG. 10 is a conceptual diagram showing the screen display of the selection display screen during the display setting process. FIG. 11 is a flowchart showing a display control process for executing a display switching process in guiding guidance.

  First, as shown in FIG. 8, the user inputs a setting for performing a search process of a moving route for moving, for example, by an input operation of the terminal input unit 130. By this setting input, a request signal for requesting a movement route is generated. When the route processing means 188 of the processing unit 180 recognizes this request signal (step S101), the processing unit 180 makes a traffic jam prediction on various information necessary for searching for a moving route, for example, the destination, the shortest distance or the shortest time. The terminal display unit 140 displays a display screen that prompts the user to input setting information such as whether or not the setting item is present.

  Then, when the route processing unit 188 recognizes various information necessary for the search for the moving route, the processing unit 180 first performs processing for recognizing the current position by the current position recognition unit 181 (step S102). The recognition means 182 performs processing for recognizing the destination set and input (step S103). Specifically, the current position recognizing means 181 converts the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110 and the GPS data relating to the current position output from the GPS receiver unit. Based on this, the current position of the vehicle is calculated to obtain the current position information. The acquired current position information is appropriately stored in the memory 170.

  In addition, the processing unit 180 controls the terminal display unit 140 with the display control unit 185 to display a display prompting the user to input a destination setting by an input operation of the terminal input unit 130. Then, when the user sets and inputs a destination by an input operation of the terminal input unit 130 in accordance with an instruction on the displayed display screen, the destination recognizing means 182 acquires destination information related to the set and input destination. The acquired destination information is appropriately stored in the memory 170.

  Here, when the destination input operation of the terminal input unit 130 is requested to obtain information about the point that is the destination point, the user can determine the point based on the display screen displayed on the terminal display unit 140. An input operation is performed to request search information. In response to the search request for the search information at this point, the processing unit 180 searches the search information related to the destination in the hierarchical information in the mesh information of the lower layer for each region using the map information, for example, by using the map information. Search information associated with the point is acquired from the storage unit 160. Then, the processing unit 180 controls the terminal display unit 140 to display search information acquired.

  It should be noted that the search information is set to input that the predetermined area of the map information including the destination is displayed, or that the user who has recognized the search information displays the predetermined area by the input operation of the terminal input unit 130, for example. In such a case, the processing unit 180 appropriately controls the terminal display unit 140 by the display control unit 185 to display the display mesh information VMx of the corresponding region. Thus, after desired map information is displayed on the terminal display unit 140, a destination point is appropriately set by an input operation of the terminal input unit 130, for example, a cursor displayed on the map display screen is moved. The point information of the destination is specified by the operation. By specifying the point information, the destination recognizing means 182 of the processing unit 180 recognizes the point information of the destination as the destination information and stores it in the memory 170 as appropriate.

  In addition, the processing unit 180 controls the terminal display unit 140 by the display control unit 185 to display a prompt for an input operation of setting items that are conditions for searching for a moving route. Then, when the user sets and inputs the setting items by the input operation of the terminal input unit 130 in accordance with the instruction on the displayed display screen, the processing unit 180 acquires the setting item information regarding the setting items that have been set and input (step S104). . The acquired setting item information is stored in the memory 170 as appropriate.

  Thereafter, the processing unit 180 acquires current position information, destination information, setting item information, current traffic jam information, predicted traffic jam status, and the like from the memory 170 by the route processing unit 188. Then, based on the acquired various information, a route for searching the moving route from the current position of the vehicle to the destination using the moving route search map information of the map information stored in the storage unit 160 and the matching data MM. Search processing is performed (step S105). Specifically, for example, when data is accumulated and prepared in the travel route search map information such as a main road, route search processing is performed using the travel route search map information, When data is not accumulated in such travel route search map information, a section from the narrow street to the main road is searched using the matching data MM. In the route search process using the matching data MM, the coordinate matching unit 187 determines whether or not the node N is the same point and recognizes the state of the road from the relationship of the link L.

  Then, the route processing unit 188 detects a plurality of moving routes, narrows down the moving routes to some based on the acquired setting item information and current traffic jam information, and some of the conditions that the user desires, for example, The travel route information on the 5 travel routes is generated. Further, the route processing means 188 generates the required time information by obtaining the required time to the destination on each moving route of the moving route information. Then, the display control unit 185 displays the calculated five candidate travel route information on the terminal display unit 140 and displays a request for selection by the user. Then, the movement route is set by an input operation in which the user selects any one of the movement route information. If only one route is set, the display requesting the selection is not displayed, and that one route is set as the moving route.

  Further, the processing unit 180 performs switching display according to setting item information indicating whether to switch and display at least one of the overall guidance screen 142 and the detailed guidance screen 143 in addition to the guidance guidance screen 141 (step S106). If so, display setting processing for setting the display status is performed (step S107). That is, as the display setting process in step S107, for example, as shown in the flowchart of FIG. 9, the display control unit 185 controls the terminal display unit 140 to specify the display base by the terminal input unit 130, that is, select a specific place. Display the screen display for For example, a selection display screen 144 for selecting a specific place to be displayed among the already set specific places as shown in FIG. 10 is displayed. The selection display screen 144 is provided with a text box 144A indicating a preset specific place, and a check box 144B in which selection is made by an input operation corresponding to the text box 144A. Then, the specific location described in the text box 144A in which the check box 144B has been input is set as a display base (step S201). In order to select another specific place or set a new specific place, for example, the map information is displayed and the cursor is moved as appropriate to select the specific place icon 142A for setting or displaying the specific place. Alternatively, coordinates such as latitude / longitude, an address, a telephone number, and the like may be input and searched by the information search unit 189 for selection.

  In this way, the specific location information regarding the specific location selected in step S201 is acquired by the specific location recognizing means 183 and stored in the memory 170 as appropriate. Further, the processing unit 180 controls the terminal display unit 140 by the display control unit 185 to display the entire guidance screen 142 and the detailed guidance screen 143 while the guidance guidance screen 141 is displayed (display start time). And a display condition screen for prompting the user to set the display time. The setting of the interval time may be set to be displayed when the vehicle approaches a specific place by a predetermined distance. When a time condition for switching display is set by an input operation of the terminal input unit 130 (step S202), information regarding the set time condition is appropriately stored in, for example, the memory 170, and the display in step S107 is performed. The setting process ends.

  After the display setting process in step S107, the processing unit 180 controls the terminal display unit 140 with the display control unit 185 to display the acquired map information and perform a guidance guidance process (step S108). In this guidance and guidance processing, the processing unit 180 is based on the data output from the speed sensor, the azimuth angle sensor, and the acceleration sensor of the sensor unit 110, and the GPS data output from the GPS receiving unit, and the movement status of the vehicle. Recognize Furthermore, the processing unit 180 displays guidance information related to the movement of the vehicle on the terminal display unit 140 based on the recognized movement status and the route guidance information included in the movement route information by the guidance notification unit 184 or a voice output unit. 150 notifies by voice output and guides the movement of the vehicle.

  Specifically, the display control unit 185 of the processing unit 180 connects the nodes N of the matching mesh information MMx acquired from the storage unit 160 with a polyline, and the road configuration described in the ring row block information constituting the matching data MM The polyline is processed based on the information, and the road in the area of the matching mesh information MMx including the movement route is displayed on the terminal display unit 140. Further, the display control means 185 obtains name information VMxA and background information VMxC, which are element data relating to elements constituting the map other than the road in the area corresponding to the matching mesh information MMx of the display mesh information VMx acquired from the storage means 160. Overlay and display. Then, the current position is superimposed on the displayed map.

  In the superimposed display of the current position, map matching processing is performed based on the matching data MM so as not to deviate from the road on which the display based on the current position information of the vehicle is displayed. That is, the processing unit 180 appropriately corrects the current position information so that the current position to be displayed is located on the matching data MM of the movement route so that the display position is on the link row where the links L are connected. In this way, the map and the current position are superimposed and displayed for guidance. In addition, when the current position reaches a predetermined position, which is a specific place such as a set store or destination, as described above, the fact that the position has been reached is displayed or indicated by voice or the like. Here, when the destination is reached, the guidance and guidance process ends. Note that, in a region other than this region, for example, when a setting input for viewing the display of another region is performed by an input operation of the terminal input unit 130, the map displayed is similar to the case where the map is displayed by search, the storage unit 160. The display mesh information VMx acquired from (1) is displayed.

  Further, in the guidance guidance process, for example, a display control process as shown in FIG. 11 is performed. That is, the display control means 185 displays the contents of traffic information such as travel route information, traffic jam prediction information, required time information, and current traffic jam information related to the travel route selected by the user, along with an icon 141A representing the current position of the vehicle. A traffic guidance display is appropriately superimposed on the map information to generate and display a guidance guidance screen 141 (step S301). Thereafter, the display control means 185 determines whether or not the set time interval has passed based on the switching display time condition set in step S202 (step S302), and determines that a predetermined time has passed. In this case, the display control means 185 generates an entire guidance screen 142 and a detailed guidance screen 143 to be displayed (step S303).

  In other words, the display control unit 185 is based on the specific position information set in step S201, and the map information of the scale ratio that includes all of the set specific places almost completely in the display area of the terminal display unit 140 that displays the map. Is read from the storage means 160. Then, an overall guidance screen 142 is generated by superimposing an icon 142A representing the movement route, the current position, and the specific place on the read map information. Further, the display control means 185 calculates the distance between the current position and each specific location based on the specific location information set in step S201 and the current location information, and selects the specific location closest to the current location. . Then, the map information of the scale ratio that is included almost completely in the display area of the terminal display unit 140 displaying the map with the specific location closest to the current position is read from the storage unit 160. And the detailed guidance screen 143 is produced | generated by superimposing the icon 142A showing a movement path | route, the present position, and the nearest specific place on the read map information.

  Furthermore, the display control means 185 switches the entire guidance screen 142 and the detailed guidance screen 143 created in step S304 from the guidance guidance screen 141 based on the information on the time condition set in step S202, and displays them for a predetermined time. Interrupt display processing is performed (step S304). For example, in a cycle of 1 minute, the entire guidance screen 142 is displayed for 4 seconds, and then the detailed guidance screen 143 is switched and displayed at a time interval for displaying 4 seconds.

[Operational effects of the first embodiment]
As described above, in the first embodiment, the guidance control screen 141 created by superimposing the current position recognized by the current position recognizing means 181 on the map information of a predetermined scale by the display control means 185; The current position and the specific location acquired by the specific location recognition means 183 include an icon 142A representing the current location and at least two points of the specific location in the map information of the scale ratio including the predetermined specific location closest to the current location. A detailed guidance screen 143 as a guidance screen created by superposition is displayed on the terminal display unit 140. For this reason, for example, it is possible to make the driver and passengers recognize the current movement situation in more detail than the configuration in which the specific location specified by the current position and the destination that are relatively far apart is simply displayed, Good guidance guidance is possible.

  In addition, the guidance guidance screen 141 is displayed during normal times, and the detailed guidance screen 143 is switched to be displayed for a predetermined time length at a predetermined timing. For this reason, it is possible to guide and guide the movement of the vehicle on the guidance and guidance screen 141 during normal times, and to recognize the detailed movement status by the switching display on the detailed guidance screen 143, and good guidance and guidance can be performed. Furthermore, since it is a switching display, the display area of the guidance display screen 141 that is normally displayed is displayed without being reduced, and satisfactory guidance can be performed.

  Furthermore, not only the detailed guidance screen 143 but also the entire guidance screen 142 as a guidance screen including all the specified specific places is displayed in a switched manner. For this reason, it is possible to easily recognize a more detailed vehicle movement state, and to perform better guidance and guidance. And as this whole guidance screen 142, by superimposing all these points in front at a scale ratio including all the specific places ahead in the traveling direction, the movement situation at the time of movement can be easily recognized, and unnecessary identification By not displaying the ground, better guidance and guidance can be achieved.

For this reason, it is possible to set a specific place as a stopover place or a guide of movement when moving based on the movement route, and usability can be further improved.

  Further, the display control means 185 displays the scale information for displaying the map information to be displayed, such as a scale ratio at which the movement situation can be easily recognized according to the situation around the vehicle when moving the vehicle, that is, a voice or display that can recognize the movement situation. Map information of scale ratio that can be notified by is used. For example, in the case of mountain roads where there are no roads or road branches in the surroundings, a relatively small scale ratio may be used, and comparisons may be made if there are similar features or road conditions in the town. The scale is a large scale value. That is, the scale ratio of the map information that can be easily recognized by the driver based on the content of the screen display on which the moving situation is displayed when the vehicle moves is set. Examples of the scale ratio setting method include a calculation method corresponding to the amount of information in the map information around the current position of the vehicle and the specific location. As a result, appropriate guidance can be performed during normal guidance. Then, by fixing this scale ratio as an initial set value, it is not necessary to set map information used for normal guidance guidance each time, the processing load can be reduced, and the guidance guidance screen 141 can be displayed quickly. Good guidance guidance is possible.

  In addition, when the display control unit 185 creates the guidance guidance screen 141, the overall guidance screen 142, and the detailed guidance screen 143, the display control unit 185 displays the content of the position of the specific location along with the icon 142A for displaying the specific location. A balloon display 142B shown is also superimposed. For this reason, the specific place to be displayed can be recognized more easily, and better guidance and movement status recognition can be obtained.

  Further, as the current position and specific location icon 142A, an icon 142A having a number corresponding to the item number displayed on the selection display screen 144 when the specific location is set in the display setting process is displayed. For this reason, a specific place can be easily recognized with a simple information processing configuration.

  And it is set as the structure selected using the selection display screen 144 from the specific place set separately as the specific place to display. For this reason, if an item frequently used as a specific place is set in advance, it is not necessary to set it every time it is displayed, and a simple operation of simply selecting it is sufficient, and usability can be improved.

  In addition, since it is configured to set a specific location to be displayed together with the setting of the travel route, it is a configuration in which the specific location is displayed together with the travel route set by the user according to the necessity of guidance guidance. The user can also be notified of the detailed movement situation, and better guidance can be provided.

[Operation of navigation system]
Next, the operation of the navigation system 200 will be described based on the drawings. In the following, similarly to the first embodiment, an operation of switching display (switching display processing when performing guidance processing by searching for a moving route) will be described. The description of the processing that is substantially the same as that of the first embodiment will be simplified. FIG. 17 is a flowchart showing a travel route search process in the navigation system. FIG. 18 is a conceptual diagram showing the screen display of the selection display screen during the display setting process. FIG. 19 is a conceptual diagram showing a screen display of the entire guidance screen.

  First, as shown in FIG. 17, the user inputs a setting for performing, for example, a search process for a moving route for moving by an input operation of the terminal input unit 130. When the processing unit 430 recognizes a setting input for performing the travel route search process (step S401), the processing unit 430 determines various information necessary for the travel route search, for example, the destination, the shortest distance or the shortest time. The terminal display unit 140 displays a display screen that prompts the user to input setting information such as whether or not to predict traffic congestion.

  When the processing unit 430 recognizes various types of information necessary for the search for the moving route by the route processing unit 555, the current position recognition unit 181 first acquires the current position information regarding the current position (step S402). The destination recognition unit 182 acquires destination information related to the destination set and input (step S403). In addition, the processing unit 430 acquires setting item information related to the setting item that has been input (step S404). The acquired current position information, destination information, and set item information are stored in the memory 420 as appropriate.

  Further, the processing unit 430 causes the display control unit 185 to display a screen display that prompts the user to set whether or not to switch between the general guidance screen 142 and the detailed guidance screen 143, and the switching is performed by an input operation of the terminal input unit 130. Recognizing a setting input for requesting display or not requesting, in the case of setting input for requesting, as in the first embodiment, for setting a specific place as shown in FIG. The selection display screen 145 is displayed or a screen display for setting a time condition for switching display is displayed, and display setting processing for prompting setting input is performed. Note that the selection display screen 145 shown in FIG. 18 is provided with an item number “5” for setting the current position of the other terminal device 400 as the specific location, for example, as shown in the overall guidance screen 146 shown in FIG. In addition, the current position of the other terminal device 400 can be superimposed and displayed. Then, the processing unit 430 acquires various information set by the display setting process together with a signal to request switching display, or a signal not to request as setting item information.

  Thereafter, the processing unit 430 controls the transceiver 410 to send the current position information, destination information, and setting item information stored in the memory 420 together with a signal requesting a search for a movement route to the server device 500. Process to send to. When transmitting the various types of information, terminal-specific information that identifies the terminal device 400 is also transmitted (step S405).

  When the server device 500 receives various types of information transmitted from the terminal device 400 via the network 300 via the interface 510 (step S406), the route processing unit 555 of the CPU 550 determines the first information based on the received setting item information.

(Step S407).

  Specifically, the route processing unit 555 uses the map information stored in the storage unit 540 to generate some travel route information that meets the conditions desired by the user. Further, when the server display control means 553 recognizes a request for switching display of at least one of the entire guidance screen and the detailed guidance screen based on the setting item information (step S408), it is the same as in the first embodiment. Based on the specific position information described in the setting item information, the entire guidance screen 142 is generated (step S409). Then, the server device 500 controls the interface 510 based on the terminal-specific information received in step S406, and information such as travel route information, current traffic jam information, traffic jam prediction information, and required time information obtained by the route search process. Various types of information related to guidance of the vehicle are appropriately transmitted to the predetermined terminal device 400 together with the map information and the entire guidance screen 142 so that the information can be superimposed and displayed by the display control means 185 of the terminal device 400 (step S410). Note that the matching data MM may be acquired in advance based on the current position information.

  And the process part 430 of the terminal device 400 which received various information (step S411) displays the acquired map information similarly to 1st Embodiment mentioned above, and performs a guidance guidance process (step S412). At the time of this guidance process, the received matching data MM is subjected to a coordinate matching process to recognize the road situation, that is, the road connection situation, and store it in the memory 420 as appropriate. Further, the processing unit 430 causes the display control unit 185 to display, for example, movement route information on the five candidate movement routes calculated by the server device 500 on the terminal display unit 140, and to request selection by the user. Make a display. Then, the movement route is set by an input operation in which the user selects any one of the movement route information.

The guidance route screen 141 is generated and displayed by superimposing travel route information, traffic jam prediction information, required time information, current traffic jam information, and the like. Then, the processing unit 430 recognizes the moving state of the vehicle based on various data output from the sensor unit 110. The information on the movement status of the vehicle is appropriately transmitted to the server device 500. Furthermore, the processing unit 430 displays guidance or information about the movement of the vehicle based on the recognized movement state and the route guidance information included in the movement route information by the guidance notification unit 184, and notifies the movement of the vehicle. Guide guidance.

  If the terminal device 400 is set to request switching display of at least one of the overall guidance screen 142 and the detailed guidance screen 143 in step S404, the display control unit 185 determines that the display control unit 185 performs the first implementation. Similar to the embodiment, the display control process shown in the flowchart of FIG. 11 is performed based on the time condition of the switching display set in step S202 in the display setting process. That is, when the switching display time interval elapses based on the time condition, the detailed guidance screen 143 is generated using the map information acquired from the server device 500. Then, an interrupt display process for displaying the entire guidance screen 142 acquired in advance and the generated detailed guidance screen 143 from the guidance guidance screen 141 only for a predetermined time based on a preset time condition is performed.
