Then, screen switching means for switching from the route input screen to the route guidance screen displaying the vehicle position mark of the vehicle is provided.
(4) The invention of claim 4 is the navigation device according to claim 3, wherein the screen switching means is prohibited when the stop of the vehicle is detected by the detecting means when the route is being guided by the route guiding means. When the input of the arbitrary route is interrupted, the interrupted location of the arbitrary route is displayed on the display monitor and switched to the route input screen. The route input means again from the interrupted location of the arbitrary route according to the arbitrary route input by the operator. The route input is started.

  According to the present invention, since the route cannot be designated by tracing the road displayed on the display monitor while the vehicle is running, the operation for designating the route by tracing the road on the display monitor with a finger while the vehicle is running. Can be prevented.

  A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. The navigation apparatus 1 of FIG. 1 can input an arbitrary route of the vehicle by tracing the road displayed on the display monitor 16. 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, and disk drive 110.

  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 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 111, the processing result is displayed on the display monitor 16 as a recommended 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. The image data includes road map drawing data and various graphic data, which are appropriately generated based on map data stored in the DVD-ROM 111 read by the disk drive 110. The navigation device 1 can perform map display and the like by using the image data generated in this way.

  The disc drive 110 is loaded with a DVD-ROM 111 on which map data to be displayed on the display monitor 16 is recorded. 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 wide areas to details, and the scale of the display map can be changed according to the operator's request. The disk drive 110 reads map data for displaying a map on the display monitor 16 from the loaded DVD-ROM 111. The map data may be read from a recording medium other than the DVD-ROM 111, such as a CD-ROM or a hard disk.

  The display monitor 16 provides the operator 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 an operator to set various commands, and is realized by a remote controller or the like. The operator manually operates the input device 17 according to instructions on the display screen of the display monitor 16 to select a 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 monitor screen displayed on the display monitor 16 is displayed through the touch panel 18. The touch panel 18 has an input function similar to the input device 17. When a map screen, various buttons, a display menu, or the like displayed on the touch panel 18 is pressed with a finger, the touch position is calculated by the touch panel control unit 19. The pressed position is input to the control circuit 11 to set a destination and to execute functions corresponding to various buttons and display menus. Further, when the road displayed on the display monitor 16 is traced with a finger, the touch panel 18 is pressed, and the traced road is input as a moving route of the vehicle.

  When the destination is set by the operator, 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 recommended route) is displayed on the screen separately from other roads by changing the display form, for example, the display color. Thereby, the operator can recognize the recommended route on the map on the screen. In addition, the navigation device 1 instructs the operator in the direction of travel using a screen or voice so that the vehicle can travel according to the recommended route or the travel route of the vehicle specified by tracing the road, thereby guiding the route of the vehicle.

  An input operation for inputting an arbitrary route by pressing and tracing the road displayed on the display monitor 16 will be described with reference to FIGS. When a route search is selected from a menu screen (not shown), a route input screen 20 is displayed as shown in FIG. FIG. 2 is a diagram for explaining the route input screen 20. On this route input screen 20, a route input mode selection region 23 and a map region 22 are displayed. In the route input mode selection area 23, a hand-drawn input mode button 24 and a navigation operation mode button 25 are displayed. In the map area 22, a vehicle position mark 21 of the vehicle and a road map 26 around the vehicle position are displayed.

  The hand-drawn input mode button 24 is a button for inputting an arbitrary route of the vehicle (hereinafter referred to as an arbitrary route) by tracing the road on the road map 26. Here, a mode in which an arbitrary route of the vehicle can be input by tracing the road on the road map 26 is referred to as a hand-drawn input mode. When the hand-drawn input mode button is pressed, an arbitrary route can be input in the hand-drawn input mode. The navigation operation mode button 25 is a button for searching for a recommended route to the destination by executing a route calculation by a predetermined algorithm in the control circuit 11. Here, a mode for searching for a recommended route to the destination by executing the route calculation by the control circuit 11 is referred to as a navigation operation mode. When the navigation operation mode button 25 is pressed, the destination on the road map is pressed to set the destination, and when the route is searched, the recommended route from the vehicle position 21 to the destination is searched and displayed.

  The road map 26 can be scrolled by pressing outside the dotted line area 27 of the road map 26. For example, the road map 26 can be scrolled upward by pressing the upper outer side of the dotted line area 27, and the road map 26 can be scrolled leftward by pressing the left outer side of the dotted line area 27. The operator scrolls the road map 26 to display the road map 26 at positions away from the own vehicle position 21 one after another, and by tracing the road displayed on the road map 26, An arbitrary route can be input from a position to a distant position.

  In this way, after pressing the hand-drawn input mode button 24, the operator inputs an arbitrary route while repeating the operation of tracing the road displayed on the road map 26 and the operation of scrolling the road map 26. For example, FIG. 3 shows a display screen on which a road map 30 is displayed and an arbitrary route 31 is input while repeating a scroll operation and a road tracing operation from the road map 26. On the display screen of FIG. 3, a confirmation button 32 and a cancel button 33 displayed when the handwriting input mode button 24 is pressed are displayed. When the confirm button 32 is pressed, the input arbitrary route 31 is confirmed as a route guidance route, and route guidance is started. When the cancel button 33 is pressed, the input arbitrary path 31 is deleted, and the input of the arbitrary path 31 can be performed again.

  Next, a case will be described in which when the operator traces the road displayed on the road map 30 and the finger reaches the intersection 34, the vehicle starts traveling before the confirmation button is operated. When the vehicle starts traveling, the input of the arbitrary route 31 is interrupted, and the display screen of the display monitor 16 is switched from the route input screen 20 to the route guidance screen 40 shown in FIG. The route guidance screen 40 is a display screen displayed on the display monitor 16 when the navigation device 1 is guiding a route. The route guidance screen 40 displays a vehicle position mark 21 of the vehicle and a road map 26 around the vehicle position. The navigation device 1 performs route guidance according to the arbitrary route 31 of the vehicle input up to the intersection 34 in FIG. On the route guidance screen 40, it is not possible to input an arbitrary route by tracing the road displayed on the road map 26.

  When the vehicle stops during route guidance, a re-input button 51 is displayed on the route guidance screen 40 as shown in FIG. When the operator presses the re-input button 51, the arbitrary route 31 of the vehicle can be input again. FIG. 6 is a display screen of the display monitor 16 displayed when the operator presses the re-input button 51. A route input screen 20 is displayed on the display screen. And the interruption location of the arbitrary path | route 31 which the input interrupted because the vehicle started driving | running | working is displayed. At this time, the arbitrary route 31 is displayed so that the intersection 34 which is an interruption point is the center of the route input screen 20. The operator can input the arbitrary route 31 from the interrupted location by tracing the road displayed on the road map 30 from the intersection 34.

  Next, an arbitrary route input process of the navigation device according to the embodiment of the present invention will be described with reference to the flowcharts of FIGS. The processing of FIGS. 7 and 8 is executed in the control circuit 11 by a program that starts when the handwriting input mode button 24 is pressed.

  In step S701, it is determined whether or not the vehicle is stopped based on the vehicle speed detected from the vehicle speed sensor 14b. If the vehicle is stopped, an affirmative determination is made in step S701 and the process proceeds to step S702. If the vehicle is traveling, a negative determination is made in step S701, and the process proceeds to step 801 in FIG. In step 702, it is determined whether or not the touch panel 18 is pressed and an operation signal is output. If the determination in step S702 is affirmative, the process proceeds to step S703. If no operation signal is detected, the process returns to step S701.

  In step S703, a corresponding link corresponding to the operation signal output from the touch panel 18 is determined. 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 111. 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 S704, the corresponding link is temporarily stored in the RAM 13. In step S705, the arbitrary route 31 is displayed along the road corresponding to the corresponding link. In step S706, it is determined whether or not the confirm button 32 has been pressed. If the confirm button 32 is pressed, an affirmative determination is made in step S706 and the process proceeds to step S707. If not pressed, a negative determination is made in step S706, and the process returns to step S701.

  In step S707, guidance information is created based on the link information stored in the RAM 13. Guidance information refers to information that the navigation device 1 instructs the operator in order for the vehicle to travel on the travel route 31. For example, when a vehicle approaches a predetermined intersection within a predetermined distance, it is information for instructing “Please turn right at the next intersection” on the display of the display monitor 16 or a speaker (not shown). In step S708, the route guidance screen 40 is displayed on the display monitor 16. In step S709, route guidance is performed based on the guidance information. When it is determined that the route guidance is finished, the arbitrary route input process is finished.

  In step S801 of FIG. 8, guidance information is created based on the link information of the link stored in the RAM 13. In step S802, the route guidance screen 40 is displayed on the display monitor 16. In step S803, a route is guided based on the guidance information.

  In step S804, it is determined whether or not the vehicle is stopped based on the vehicle speed detected from the vehicle speed sensor 14b. If the vehicle is stopped, an affirmative determination is made in step S804, and the process proceeds to step S805. If the vehicle is traveling, a negative determination is made in step S804, and the process returns to step 803. In step S805, the re-input button 51 is displayed on the route guidance screen 40.

  In step S806, it is determined whether the re-input button has been pressed. If it is pressed, an affirmative determination is made in step S806, and the process proceeds to step S807. If not pressed, a negative determination is made in step S806, and the process returns to step S803. In step S807, route guidance is stopped. In step S808, the temporarily stored information on the corresponding link is read from the RAM 13, and the interrupted point of the arbitrary route 31 input earlier, that is, the destination-side node of the terminal link is displayed at the center of the screen. A route input screen 20 is displayed on the display monitor 16. Then, the process proceeds to step S702 in FIG.

The navigation device 1 according to the above embodiment has the following effects.
(1) While the vehicle is running, an arbitrary route cannot be input by tracing the road displayed on the display monitor 16 with a finger. Therefore, an operation in which the operator traces the road displayed on the touch panel 18 with his / her finger and inputs the arbitrary route 31 while the vehicle is traveling can be prevented.
(2) When the vehicle starts to travel before the arbitrary route of the vehicle is determined, the route is guided by the arbitrary route 31 up to the time when the input is interrupted. Therefore, even if it is not necessary to input all the arbitrary routes to the destination at once, the route guidance can be received by the arbitrary route input to the destination while repeating the input of the arbitrary route and the route guidance.
(3) While inputting the arbitrary route of the vehicle, even if the input operation of the arbitrary route 31 is interrupted due to the start of traveling of the vehicle, when the input operation of the arbitrary route is resumed by stopping the vehicle, information of the corresponding link temporarily stored Is read from the RAM 13 and the tip of the arbitrary path 31 is displayed. Therefore, finger input of the desired route can be started from the arbitrary route 31 at the time when the input operation is interrupted, and it is not necessary to input the route again from the beginning, and the arbitrary route 31 can be input efficiently.
(4) The route guidance screen 40 is displayed when the vehicle starts traveling while inputting the arbitrary route 31 of the vehicle. As a result, it is possible to reliably grasp that the route input in the hand-drawn input mode is prohibited, and it is not possible to input the arbitrary route 31, but the road displayed on the touch panel 18 while the vehicle is traveling is touched with a finger. The useless operation of tracing can be prevented.

The navigation apparatus 1 of the above embodiment can be modified as follows.
(1) When the re-input button 33 is pressed, the route input screen 20 is displayed on the display monitor 16 so that the interruption point of the arbitrary route 31, that is, the destination side node of the end link is displayed at the center of the screen. If the interruption location of the route 31 is displayed, the display form of the arbitrary route 31 when the screen is switched to the route input screen 20 is not limited to the embodiment. For example, the route input screen 20 may be displayed in the same display form as when the input of the arbitrary route 31 is interrupted.
(2) Although the road map 26 is scrolled by pressing outside the dotted line area 27 of the road map 26, the method of scrolling the road map 26 is not limited to the embodiment. For example, an arrow button may be displayed on the road map 26, and the road map 26 may be scrolled in the direction of the arrow when the arrow button is pressed.
(3) Although it is detected whether the vehicle is stopped based on the vehicle speed detected from the vehicle speed sensor 14b, it may be detected from the brake position of the parking brake, the key position of the ignition switch, or the like.
(4) Although an arbitrary route is input by tracing the road on the road map displayed on the display monitor 16 with a finger, it may be input with a touch pen or a touch strap.

  In addition to such modified examples, various modified examples are assumed. In other words, the present invention can be applied to various navigation devices that prohibit the route screen pressing input on the route guidance screen while traveling.
