The control unit 17 can specify a user's favorite restaurant (such as a ramen shop or a pasta shop) or a user's favorite destination (such as a sightseeing spot) from the learned history information.

  Further, in the map display process, the control unit 17 displays a jump button indicating a destination to jump and move on the map display screen based on the map data. When a specific jump button is operated by a user operation, the jump button is displayed. The map display area is changed so as to jump to the position indicated by.

  In FIG. 2, the flowchart of the map display process of the control part 17 in this embodiment is shown. When the ignition switch of the vehicle is turned on, the navigation device 1 is in an operating state, and the control unit 17 starts the processing shown in FIG.

  First, the display mode setting is read (S100). The display mode indicates the type (content) of the jump button indicating the position to jump and is stored in the internal memory of the control unit 17. FIG. 3 shows the correspondence between display modes and jump buttons to be displayed. As shown in the figure, the display mode includes a prefecture mode that displays jump buttons such as prefectures, cities, towns and villages, a terrain display mode that displays jump buttons such as mountains, valleys, rivers, seas, and beaches, and a company name. A POI display mode for displaying a POI (Point of Interest) stored in map data such as a university name, a large-scale facility, a municipal office, a restaurant, and a memory point mode for displaying a memory point stored in a memory There are a history point mode for displaying history points stored in a memory and a related point display mode for displaying related points related to a map display point. Some display modes are hierarchized into a plurality of levels. For example, in the prefecture mode, it is hierarchized into three levels: prefecture, county, and municipality. The setting of the display mode can be changed by processing by the control unit 17 or user operation. It is also possible to set the display mode by combining the display mode and the hierarchical level.

  Next, the display state of the map is read (S102). Specifically, a map display area, a display scale, information indicating whether guidance is being performed, and the like are read.

  Next, the jump button to be displayed is specified (S104). Specifically, a jump button indicating a movement destination whose distance from the current position is less than a predetermined threshold is extracted, and displayed on the display unit 14 in accordance with the display mode setting read in S100 above. Identify the jump button.

  FIG. 4 shows the relationship between the display mode and the threshold in the present embodiment. For example, in the prefecture mode, it is 30 kilometers (km) for prefectures, 5 kilometers (km) for county cities, 1 kilometer (km) for village towns, and 200 meters (m) for street addresses. In the terrain display mode, the distance is 10 kilometers (km), and in the POI display mode, the distance is 5 kilometers (km). This threshold value can be changed by a user operation.

  Therefore, for example, when the display mode is set to the POI display mode, a jump button indicating a destination where the distance to the current position is less than 5 kilometers is extracted and specified as a jump button to be displayed on the display unit 14. The

  When the display mode is set by combining the display mode and the hierarchized level, the jump button to be displayed on the display unit 14 is specified according to the combination of the display mode and the level.

  Also, as shown in FIG. 5, the jump buttons displayed on the display unit 14 are made different depending on the display scale (map scale). For example, when the display scale (map scale) is 100 kilometers (km) or more and the display mode is set to the prefecture mode, the jump button indicating the county city, town, and street is not displayed. If the display scale (map scale) is less than 1 kilometer (km) and the display mode is set to the prefecture mode, the prefecture, county city, town, and street number are displayed. A jump button is displayed.

  Next, based on the history information learned by the history information learning process, it is determined whether to reflect the user's preference on the display of the jump button (S106). Specifically, a screen for confirming whether or not the user's preference is reflected on the display of the jump button is displayed on the display unit 14, and it is determined whether or not the user's preference is reflected on the display of the jump button.

  If the user performs an operation indicating that the user's preference is not reflected on the display of the jump button, the determination in S106 is NO and the jump button is displayed on the map (S110). Specifically, the jump button specified in S104 is displayed over the map display screen.

  FIG. 6 shows a display example of the jump button when the display mode is set to the prefecture mode. In this figure, a current position mark P indicating the current position, hierarchized jump buttons J1 to J7, return buttons B1 to B3, and delete button E1 are shown, and the map is omitted.

  Jump button J1 (A town in the figure), jump button J2 (B town) and jump button J3 (C town in the figure) are displayed as level 1, jump button J4 (D city) and jump button J5 ( E city) is displayed as level 2, and jump button J6 (F prefecture) and jump button J7 (G prefecture) are displayed as level 3. As shown in the figure, display areas of levels 1 to 3 are provided in a hierarchy on concentric circles centering on the vehicle position mark P, and jump buttons J1 to J7 are displayed in the corresponding display areas. The

  Each jump button J1 to J7 is displayed in the direction of each destination indicated by each jump button J1 to J7 with reference to the own vehicle position mark P displayed at the center of the display area. For example, a jump button J1 indicating A town located north of the own vehicle position mark P is displayed above the own vehicle position mark P, and a jump button J2 indicating B town located west of the own vehicle position mark P is The vehicle position mark P is displayed on the left side.

  The return button B1 is a button for returning to the display of the display area including the current position mark P1, and the return button B2 (denoted as “jump forward one” in the figure) is before jumping once. This button is used to return to the display of the map display area displayed on the display unit 14 and the return button B3 (denoted as “jump forward two” in the figure) is displayed on the display unit 14 before jumping twice. This is a button for returning to the display of the map display area that was displayed in.

  The erase button E1 is a button for erasing the display of each of the jump buttons J1 to J7.

  FIG. 7 shows a jump button display example when the display mode is set by combining the display mode and the hierarchized level.

  The jump button J10 (in the figure, pasta shop 1), the jump button J11 (in the figure, pasta shop 2) and the jump button J12 (in the figure, pasta shop 3) are displayed as level 1 of the POI display mode. J13 (Yakiniku restaurant 1 in the figure) and Jump button J14 (Ramen shop 1 in the figure) are displayed as level 2 of the POI display mode. Jump button J15 (Memory point 1 in the figure), Jump button J16 ( In the figure, memory point 2) is displayed as level 3 in the memory point mode.

  If the user performs an operation indicating that the user's preference is reflected on the display of the jump button, the determination in S106 is YES, and then the jump button to be displayed is corrected (S108). Specifically, the user's preference is estimated based on the history information learned by the history information learning process, and the jump button displayed on the display unit 14 is corrected according to the estimated user's preference. For example, when it is estimated that the user likes ramen, in addition to the levels 1 to 3 shown in FIG. 5, the ramen shop located at a distance less than the threshold is extracted, and the POI indicating the extracted ramen shop is set to level 4. Add as

  Therefore, in S110, in addition to the levels 1 to 3 shown in FIG. 5, an image obtained by adding POI indicating a ramen shop as level 4 is displayed on the display unit 14.

  In S112, it is determined whether or not a specific jump button has been selected by operating the touch switch of the operation unit 12 or the remote controller 16a. In S120, it is determined whether or not a specific return button has been selected, and in S124. It is determined whether or not the delete button has been selected.

  If a specific jump button is selected and operated by the user, the determination in S112 is YES, and the jump is moved to the position indicated by the selected jump button (S114). Specifically, the map display area is changed so as to jump to the movement destination indicated by the jump button selected and operated.

  Further, the display scale is changed according to the jump button selected and operated (S116). Specifically, an appropriate display scale is calculated according to the jump button that has been selected and operated to change the display scale. In the present embodiment, the display scale is changed so that the entire destination indicated by the jump button that has been selected is included in the map display area. For example, if the display mode is set to prefecture mode and a user selects a prefecture, the display scale is changed so that the entire prefecture is included in the map display area, and the user selects a town. When operated, the display scale is changed so that the entire town is included in the map display area.

  Next, the display history is stored (S118). Specifically, the map display area before the jump display is stored in the internal memory of the control unit 17, and the process returns to S100. In this way, the history of the map display area before jump display is stored in the internal memory of the control unit 17.

  When a specific return button is selected and operated by operating the touch switch of the operation unit 12 or the remote controller 16a with the jump button displayed on the map as shown in FIG. 6, the determination in S112 is NO and the determination in S120 is It becomes YES and jumps to the position before jumping (S122). That is, it returns to the display of the map display area displayed on the display unit 14 before jumping based on the display history stored in the internal memory of the control unit 17 in S118. For example, when the return button B1 shown in FIG. 6 is selected, the display is returned to the display area including the current position mark P1, and the return button B2 (denoted as “jump to previous” in the figure) is selected. Then, the display is returned to the map display area displayed on the display unit 14 before jumping once, and the return button B3 (denoted as “jump forward two” in the figure) is selected and operated. Return to the display of the map display area displayed on the display unit 14 before jumping twice.

  If the user selects the delete button E1 with the jump button displayed on the map as shown in FIG. 6, the determination in S124 is YES and the jump button is deleted (S126). Specifically, the display of the return buttons B1 to B3 together with the jump buttons J1 to J7 as shown in FIG. 6 is deleted to display only the map, and this processing is terminated.

  According to the above configuration, when the jump button indicating the destination to jump and move is displayed on the map display screen based on the map data, and it is determined that the jump button has been selected, the destination is indicated by the jump button. Since the map display area is changed so as to jump, a desired map display area can be displayed with a single selection operation, and operability can be improved.

  In addition, a jump button indicating a movement destination whose distance from the current position is less than a predetermined threshold is extracted, and the extracted jump button is displayed on the display unit. It is possible to change the map display area so that only the jump button whose destination is within the range is displayed on the display unit and jumps to the destination indicated by the jump button.

  In addition, since a jump button corresponding to the set display mode and level is displayed on the display unit, the user sets the desired display mode and level so that the user can select the jump button corresponding to the desired display mode and level. It can be displayed.

  Also, since the jump information that learns history information associated with the driving guidance, estimates the user's preference from this history information, and is displayed on the display unit to match the user's preference is corrected, the jump button that matches the user's preference Is displayed on the display unit, and the user can select and operate the jump button displayed on the display unit.

  Also, the history information of the map display area that has been jump displayed is stored, and a return button for returning to the display of the map display area that was displayed on the display section before the jump movement is displayed on the display section. When it is determined that the selection operation has been performed, the display is returned to the display of the map display area that was displayed on the display unit before the jump movement based on the history information, so that the user can easily display on the display unit before the jump movement. The operation of returning to the display of the map display area can be performed.

  In this embodiment, as shown in FIG. 6 and FIG. 7, display areas of each level are provided on concentric circles centered on the vehicle position mark P, and each display area has a respective display area.
