A route correcting unit that corrects the route by pressing a part of the route, and a route guiding unit that guides the route using the route corrected by the route correcting unit.

  According to the present invention, the route that has been designated before is corrected and the route is designated, so that the route that the occupant wants to pass through can be designated easily.

  A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. The navigation device 1 in FIG. 1 can designate a route through which an occupant passes by tracing on the touch panel 18. The navigation device 1 includes a control circuit 11, ROM 12, RAM 13, current location detection device 14, image memory 15, display monitor 16, input device 17, touch panel 18, data storage unit 110, and disk drive 111.

  The touch panel 18 is a transparent touch switch laminated on the surface of the display monitor 16, and an image displayed on the display monitor 16 is displayed through the touch panel 18. The touch panel 18 sends a signal corresponding to the operation position on the touch panel 18 to the touch panel control unit 19, and the touch panel control unit 19 calculates the pressed position of the touch panel 18. The disc drive 111 is loaded with a DVD-ROM 112 on which map data to be displayed on the display monitor 16 is recorded.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. When the control circuit 11 performs a predetermined route search process based on the map data stored in the DVD-ROM 112, the processing result is displayed on the display monitor 16 as a search route.

  The current position detection device 14 is a device that detects the current position of the vehicle. For example, a vibration gyro 14a that detects the traveling direction of the vehicle, a vehicle speed sensor 14b that detects the vehicle speed, and a GPS signal from a GPS (Global Positioning System) satellite. It consists of a GPS sensor 14c and the like. The navigation device 1 determines a map display range, a route search start point, and the like based on the current location of the vehicle detected by the current location detection device 14, and displays the current location on the map.

  The image memory 15 stores image data to be displayed on the display monitor 16. This image data includes road map drawing data and various graphic data, which are appropriately generated based on map data stored in the DVD-ROM 112 read by the disk drive 111. The navigation device 1 can perform map display and the like by using the image data generated in this way.

  The display monitor 16 provides the occupant with various information such as a road map near the vehicle position as a screen display based on various information such as map data. The input device 17 has an input switch for a passenger to set various commands, and is realized by a remote controller or the like. The occupant manually operates the input device 17 according to instructions on the display screen of the display monitor 16 to select the destination and set the destination.

  As described above, the touch panel 18 is a transparent panel provided on the monitor screen of the display monitor 16, and the display screen displayed on the display monitor 16 is displayed through the touch panel 18. Further, when the display screen of the display monitor 16 is pressed, the touch panel 18 is pressed. The touch panel 18 has an input function like the input device 17. When the map screen, various buttons, display menu, etc. displayed on the display monitor 16 are pressed with a finger, the touch panel 18 is pressed, and the touch position is calculated by the touch panel control unit 19. Then, the calculated pressing position is input to the control circuit 11, and a destination is set, or functions corresponding to various buttons and display menus are executed. Further, when the road displayed on the display monitor 16 is traced with a finger, the traced road is designated as a route desired to pass. The traced road is displayed as a route. The route is displayed by changing the display form, for example, the display color and the line width from those of other roads.

  On the other hand, the navigation apparatus 1 can also obtain a route by route computation. When the destination is set by the occupant, the navigation apparatus 1 performs a route calculation from the current location detected by the GPS sensor 14c to the destination based on a predetermined algorithm. The route thus obtained (hereinafter referred to as a searched route) is displayed on the screen in a manner different from other roads by changing the display form, for example, the display color. Thereby, the passenger can recognize the search route on the map on the screen. In addition, the navigation device 1 instructs the occupant to travel in the traveling direction using a screen, voice, or the like so that the vehicle can travel according to the searched route or the route designated by the occupant, thereby guiding the vehicle.

  The data storage unit 110 is configured by a rewritable recording medium such as a memory or a hard disk, and stores data necessary for various functions of the navigation device 1. Information stored in the data storage unit 110 is appropriately read and used by the control circuit 11. The data storage unit 110 stores, as hand-drawn history data, a route that has been route-guided by a route previously designated by the occupant by tracing the road and route guidance information.

  The hand-drawn history data will be described with reference to FIG. The handwritten history data 20 includes a data number 21, a route designated by the passenger tracing the road, a route guidance date 22, a start time 23 from the departure point, an arrival time 24 at the destination, and a destination from the destination. The time required 25 actually taken to the ground and the hand-drawn route ID 26 attached to the designated route are stored. In addition, hand-drawn route ID information 27 is added to each hand-drawn route ID 26. The hand-drawn route ID information 27 includes the hand-drawn route ID 26, the number of links 28 constituting the route specifying the route by tracing the road, and designation. The link ID 29 of the link constituting the route, the hand-drawn start point 210 that is the starting point of the designated route, and the information of the hand-drawn end point 211 that is the destination of the designated route.

  The disk drive 111 reads map data for displaying a map on the display monitor 16 from the loaded DVD-ROM 112. The map data includes map display data, route search data, and the like. The route search data includes road link information and node information stored in the map data. The map display data has map data of a plurality of scales from a wide area to details, and the scale of the display map can be changed according to the passenger's request. The map data may be read from a recording medium other than the DVD-ROM 112, such as a CD-ROM or a hard disk.

  Next, an operation for designating a route using the hand-drawn history data 20 of the navigation device 1 according to the embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a diagram for explaining a hand-drawn history selection screen 31 for selecting a desired route from routes previously designated by the occupant by tracing the road. The hand-drawn route selection screen 31 is displayed when a button (not shown) in a mode in which a route can be specified by tracing a road is pressed. On the hand-drawn route selection screen 31, the data number 21 stored in the hand-drawn history data 20, the route guidance date 22, the start time 23 from the departure point, the arrival time 24 at the destination, and from the departure point to the destination The required time 25 is displayed. The occupant can select a desired route by pressing the data number 21 based on the date 22 on which the route guidance is performed, and can display the desired route on the display monitor 16. In this embodiment, it is assumed that the occupant has pressed the data number “2”.

  FIG. 4 is a diagram for explaining a display screen displayed on the display monitor 16 when the occupant presses the data number 21 on the hand-drawn route selection screen 31. A road map 40 is displayed on the display monitor 16. On the road map 40, a route 41 corresponding to “2” of the data number 21 is displayed, and a starting point 42 and a destination 43 of the route 41 are displayed. A route data number 21 is displayed in the upper left part of the road map 40. In addition, a hand-drawn history button 44, a detail button 45, a wide area button 46, an erase button 47 and a confirm button 48 are displayed below the road map 40.

  When the hand drawn history button 44 is pressed, the hand drawn route selection screen 31 is displayed on the display monitor 16. Then, the data number 21 can be pressed to change the route displayed on the display monitor 16 to another route. When the detail button 45 is pressed, the detail display process is enabled. When the road map 40 is pressed while the detailed display process is valid, a detailed map centered on the pressed position is displayed. When the detail button 45 in a state where the detail display process is valid is pressed, the detail display process is invalidated, and the detailed map is not displayed even when the road map 40 is pressed. When the wide area button 46 is pressed, the display returns from the detailed map to the road map 40.

  When the erasing button 47 is pressed, the erasing process becomes effective. If the route 41 displayed on the display monitor 16 is traced in a state where the erasing process is valid, the traced portion of the route 41 is erased. The occupant can modify the previously designated route by partially erasing the route 41 and tracing the road again to redesignate the route. When the correction button 47 in a state where the erasing process is valid is pressed, the erasing process becomes invalid. Then, even if the path 41 is traced, the traced part is not erased. When the confirm button 48 is pressed, the route 41 displayed on the display monitor 16 is confirmed as a route guidance route, and route guidance is started.

  It is assumed that the passenger presses the detail button 45, presses a point 49 on the road map to display the detailed map, and partially corrects the route 41. FIG. 5 is a diagram for explaining the erasing process of the route 41 and shows a detailed map 50 displayed on the display monitor 16. Similar to the road map 40, the detailed map 50 displays the data number 21 of the route 41. Further, similarly to the road map 40, a hand-drawn history button 44, a detail button 45, a wide area button 46, an erase button 47, and a confirm button 48 are displayed below the detailed map 50. Further, the pressed point 49 is displayed on the detailed map 50.

  Here, it is assumed that the occupant corrects the road desired to pass through the route 41 from the road 51 to the road 52. Here, the road 51 is displayed on the road map 40, but the road 52 is not displayed on the road map 40 but only on the detailed map 50 because the road 52 is relatively narrow. As shown in FIG. 5, the occupant presses the erasing button 47 to enable the erasing process, and then traces a portion of the road 41 of the route 41 to erase a part of the route 41. Then, as shown in FIG. 6, after the erasing button 47 is pressed to invalidate the erasing process, the road 52 is designated as a part of the route 41 by tracing the road 52. As described above, the occupant can correct a part of the route 41 from the road 51 to the road 52.

  The occupant presses the wide area button 46 to display the road map 40 on the display monitor 16. Then, as shown in FIG. 7, the confirm button 48 is pressed to confirm the corrected route 41 as a route guidance route. Then, route guidance is started on the corrected route 41.

  Next, the correction processing of the route stored in the hand-drawn history data 20 of the navigation device 1 according to the embodiment of the present invention will be described using the flowcharts of FIGS. 8 and 9 is executed in the control circuit 11 by a program that starts when a road map in a mode in which a route can be designated by tracing the road with a finger is displayed on the display monitor 16.

  In step S 801, the route 41 selected from the hand-drawn route selection screen 31 is read from the hand-drawn history data 20 stored in the data storage unit 110. In step S802, it is determined whether or not the erase button 47 is pressed and the route erase process is valid. If it is valid, an affirmative determination is made in step S802, and the process proceeds to step S803. If invalid, a negative determination is made in step S802, and step S802 is repeated.

  In step S803, it is determined whether or not the display screen of the display monitor 16 is pressed, that is, the touch panel 18 is pressed and the touch panel 18 outputs an operation signal. If an operation signal is detected, an affirmative determination is made in step S803, and the process proceeds to step S804. If no operation signal is detected, step S803 is repeated. In step S804, the corresponding link corresponding to the pressed position is determined from the operation signal output from the touch panel 18.

  Corresponding links are determined as follows. That is, the pressing position on the touch panel 18 is calculated based on the operation signal, and further the pressing position on the map is calculated. Then, nodes within a predetermined range from the pressed position on the map are extracted from the map data stored in the DVD-ROM 112. A link connected to the extracted node is extracted, and the distance from the link to the pressed position on the map is calculated. Then, the link having the smallest calculated distance is determined as the corresponding link.

  In step S805, the corresponding link is deleted from the route 41. In step S806, it is determined whether or not the erase button 47 in the state where the erase process is valid is pressed again to invalidate the erase process. If it is invalid, an affirmative determination is made in step S806, and the process proceeds to step S901 in FIG. If it is valid, a negative determination is made in step S806, and the process returns to step S803.

  In step S901 in FIG. 9, it is determined whether or not the display screen of the display monitor 16 is pressed, that is, the touch panel 18 is pressed and the touch panel 18 outputs an operation signal. If an operation signal is detected, an affirmative determination is made in step S901, and the process proceeds to step S902. If no operation signal is detected, step S901 is repeatedly executed. In step S902, the corresponding link is determined by the same method as in step S804 in FIG. In step S903, the corresponding link is added to the path 41.

  In step S904, it is determined whether the confirmation button 48 has been pressed. If the confirm button 48 is pressed, an affirmative determination is made in step S904 and the process proceeds to step S905. If not pressed, a negative determination is made in step S904, and the process returns to step S901. In step S905, the corrected route link is stored in the RAM 13. In step S906, route guidance is started based on the route information stored in the RAM 13. In step S907, the route history data 20 stores the route guidance information. Then, the setting process ends.

The navigation device 1 according to the above embodiment has the following effects.
(1) Since the previously designated route 41 is read out and modified to designate the route 41, it is not necessary to designate the route again from the beginning, and the route that the occupant wants to pass through can be designated easily.
(2) Since the route 41 can be corrected by enlarging and displaying the location to be corrected, it is possible to specify a road that is desired to pass freely from the road that is displayed only on the detailed map 50 to the main road.

The navigation device 1 of the above embodiment can be modified as follows.
(1) The handwritten history data 20 stores the data number 21, the route guidance date 22, the start time 23, the arrival time 24, the required time 25, and the handwritten route ID 26. The data that is provided is not limited to the embodiment. For example, the name of the departure place or destination may be stored. For example, the name of a leisure facility may be stored as a home, and the name of a leisure facility as a destination.

For example, the departure place and the destination may be displayed. In addition, when displaying the departure place, the place name at the hand-drawn start point 210 and the facility name of the nearby facility may be displayed. When displaying the destination, the place name at the hand-drawn end point 211 and the facility name of the nearby facility May be displayed.

(3) In addition to displaying the route 41 on the road map 40, a schematic diagram 100 showing the road through which the route 41 passes may be displayed on the display monitor 16 as shown in FIG. In the schematic diagram 100, roads 101 to 103 through which the route 41 passes are displayed in addition to the departure point 42 and the destination 43. On the roads 101 to 103, the names of roads such as “National road ○ line” and “Prefectural road x line” are displayed. The roads 101 to 103 are extracted from the link information of the links constituting the route 41. Even if it is not clear from the road map 40 what kind of road the route 41 is passing, the roads 101 to 103 through which the route 41 passes can be recognized by displaying the schematic diagram 100. Further, the occupant can display the road map 40 by pressing the road map button 104. A schematic map button (not shown) is displayed on the road map 40. When the schematic map button is pressed, the schematic map 100 can be displayed.
