JP 2000-111354 A

  In the navigation device described in Patent Document 1, a road can be arbitrarily specified, but there is a problem that a road that does not want to pass is erroneously specified.

The navigation device according to the present invention includes a display monitor that displays a road map and a touch panel that detects a touch position on the display monitor, and the touch position on the road displayed on the display monitor is the navigation device. Position detecting means for detecting, based on the output of the touch panel, that the last touch position has reached within a predetermined distance from a predetermined geographical position when continuously changing along the road; When it is detected by the position detection means that the distance is within the predetermined distance, display control means for pop-up displaying an enlarged view including the geographical position on the display monitor is provided.

  According to the present invention, when the road touch position displayed on the display screen approaches a geographical position such as an intersection, various information such as an enlarged intersection view is displayed on the display screen. The guidance route can be input while confirming.

  A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. In the navigation apparatus 1 of FIG. 1, a guidance route is input by designating a road on a road map displayed on a monitor. 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 disk drive 110 is loaded with a DVD-ROM 111 in which map data to be displayed on the display monitor 16 is recorded, and reads out map data for displaying a map on the display monitor 16. The map data includes map display data, route search data, and the like, and the display and route search data include road link information and node information. 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 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 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 touch panel 18 is pressed, and the traced portion of the road (designated range of the road) is input as a vehicle guidance route. That is, the designated range of the road pressed on the display monitor 16 is input as a guide route. 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 guidance route, and guides the route of the vehicle.

  When the destination is input, 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, thereby guiding the route of the vehicle.

  In the navigation device 1 of the present embodiment, when the operator traces a road with his / her finger and inputs a guidance route, when the pressed position approaches the intersection, an enlarged view of the intersection at the intersection is displayed. Hereinafter, the intersection enlarged view display of embodiment of this invention is demonstrated with reference to FIGS.

  The guidance route input operation will be described with reference to FIG. FIG. 2 is a diagram for explaining a route that the operator is going to trace and input from now on. Reference numeral 21 shown on the road map 20 is a starting point, and reference numeral 22 is a destination. The route 23 input by the operator is as follows. (1) Pass the road 25a from the departure point 21, and turn left at the intersection 26a. (2) Further, turn right at the intersection 26c through the road 24a. (3) Then, the vehicle passes the road 25b and goes straight through the intersection 26d to reach the destination.

  When the operator presses and releases the departure place 21, the road map 20 is scrolled so that the pressed position is displayed at the center of the display screen, and a departure place mark is displayed at the departure place 21. Then, after pressing the departure place 21 again, the guide route can be input by tracing the road. The road map 20 displayed on the display monitor 16 is scrolled so that the pressed position is displayed at the center of the display screen. Therefore, as shown in FIG. 3, the road map 20 is scrolled to the left side by shifting the pressing position from the center to the right side, the simultaneously traced road is designated as the designated range, and the guide route 31 is input.

  When the pressed position (tracing position) of the finger tracing the road reaches within a predetermined distance from the intersection 26a, an enlarged view (intersection enlarged view) 40 of the intersection 26a is superimposed on the road map 20 on the pop-up screen as shown in FIG. Displayed. The intersection enlarged view 40 is a road map in which the vicinity of the intersection 26 a is enlarged, and the scale ratio is larger than that of the road map 20. In the enlarged intersection view 40, facilities around the intersection 26a are displayed as icons 41 to 44.

  When the operator scrolls the road map 20 and traces the road in a direction to turn left at the intersection 26a, when the operator leaves the intersection 26a by a predetermined distance or more, the display of the enlarged view of the intersection ends as shown in FIG. When the tracing position reaches within a predetermined distance from the next intersection 26c, an enlarged intersection view (not shown) of the intersection 26c is displayed.

  Next, with reference to the flowchart of FIG. 6, the entire processing from when a guidance route is input until route guidance is performed will be described. The processing in FIG. 6 is executed in the control circuit 11 by a program that starts when a mode for inputting a guidance route by tracing a road is selected.

  In step S601, route input processing for a guidance route is performed. Details of the route input process will be described later. In step S602, guide information is created from the link information of the guide route stored in the RAM 13 by the route input process. This guidance information is information for instructing the occupant on a display screen or the like so that the vehicle travels along the guidance route.

  In step S603, it is determined whether an operation for starting route guidance has been performed. When the start operation is performed, an affirmative determination is made in step S603, and the process proceeds to step S604. If the start operation has not been performed, step S603 is repeated. In step S604, route guidance processing is performed to route the vehicle.

  The route input process in step S601 will be described with reference to the flowchart in FIG. In this route input process, when the tracing position approaches the intersection, an enlarged view of the intersection is displayed.

  In step 701, it is determined whether the touch panel 18 is pressed and an operation signal is output. If step S <b> 701 is positively determined, the process proceeds to step S <b> 702. If no operation signal is detected, step S701 is repeated. In step S702, a departure point mark is displayed at the first pressed position. This is performed by determining a link corresponding to the pressed position, recognizing the start point node as the departure place, and displaying the departure place mark, as in step S704 described later.

  In step S703, it is determined whether the first pressing position is pressed again. If it is determined that the button has been pressed, an affirmative determination is made in step S703 and the process proceeds to step S704. If it is determined that it is not pressed again, a negative determination is made in step S703, and step S703 is repeated. In step S704, 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 with the smallest calculated distance is determined as the corresponding link.

  In step S705, the corresponding link is temporarily stored in the RAM 13. In step S706, the guide route 31 is displayed along the road corresponding to the corresponding link. In step S707, an intersection closest to the pressed position is extracted. In step S708, it is determined whether the distance between the pressed position and the extracted intersection is within a predetermined distance. If it is within the predetermined distance, an affirmative determination is made in step S708 and the process proceeds to step S709. If not within the predetermined distance, a negative determination is made in step S708, and the process proceeds to step S712. In step S709, an enlarged intersection map of the extracted intersection is displayed on the display monitor 16.

  In step S710, it is determined whether the touch panel 18 has been pressed. If it is pressed, an affirmative determination is made in step S710, and the process returns to step S704. If not pressed, a negative determination is made in step S710, and the process proceeds to step S711. In step S711, a destination mark is displayed at the last pressed position. In step S712, the extracted intersection enlarged view is not displayed. That is, when the extracted intersection enlarged view is displayed, the display is terminated, and when it is not displayed, it is not displayed as it is. Then, the process proceeds to step S710.

The navigation device 1 according to the above embodiment has the following operational effects.
(1) When the tracing position on the road displayed on the display screen approaches the intersection 26a, the intersection enlarged view 40 is displayed. Therefore, the road of the intersection 26a is confirmed while checking the facilities 41 to 44 displayed in the intersection enlarged view 40. Can be traced. Therefore, it is possible to prevent the intersection 26a from turning in the wrong direction and tracing the road that does not want to pass by mistake.

The navigation apparatus 1 of the above embodiment can be modified as follows.
(1) The scale ratio of the intersection enlarged view may be changed according to the number of facilities displayed in the enlarged view. For example, when the number of facilities to be displayed on the enlarged intersection map is small, the scale ratio of the enlarged intersection map may be reduced, and when the number of facilities to display the enlarged intersection map is large, the scale ratio of the enlarged intersection map may be increased. . By doing in this way, it can prevent that the number of facilities displayed on an intersection enlarged view is too many, and it becomes impossible to identify each facility.

(2) The scale ratio of the intersection enlarged view may be changed between the city, the urban area, the countryside, and the suburbs. Since facilities are densely populated in cities and urban areas, there are too many facilities displayed when the scale of the enlarged intersection map is small, so that each facility cannot be recognized. On the other hand, in the countryside and suburbs, there are cases where there are too few facilities displayed when the scale of the enlarged map of the intersection is large, and there is insufficient information such as facilities for checking the intersection. Therefore, the scale of the enlarged map of the intersection in the city and the city area is increased, and the scale of the enlarged map of the intersection in the country and the suburbs is reduced. By doing in this way, an intersection can be confirmed reliably by an intersection enlarged view.

(3) Although the guidance 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.

(4) The enlarged intersection view displayed when the finger tracing position tracing the road approaches the intersection may be the same as the enlarged intersection view displayed when the route guidance is actually started. In this case, it is not necessary to newly create an enlarged intersection view.

(5) The information displayed on the pop-up screen is not limited to the information regarding the intersection as long as it is information regarding the geographical position. For example, information about various geographical locations such as restaurants, museums, parks, historic sites, and gas stations may be displayed on a pop-up screen.

(6) Although the route is input by tracing the road, the input route may be designated by touching the road at predetermined intervals.

(7) When the trace position on the road displayed on the display screen approaches the intersection 26a, the enlarged intersection map 40 is displayed. However, when the trace position reaches the intersection 26a, the enlarged intersection map 40 is displayed. It may be.
