  The present invention relates to a navigation device having a touch panel on the front surface of a display device.

  There is a navigation device that displays a map on a display device and receives designation of a specific point (for example, a destination) via a touch panel. Such a navigation device selects a road (link) in the vicinity of a designated point and sets it as a destination or the like (see Patent Document 1, etc.).

JP 2006-284342 A

  However, when there are a plurality of roads around the designated point, the user may not be able to easily select the intended road. In such a case, it is possible to touch the intended road accurately instead of touching the approximate point. However, when multiple roads are crowded in a narrow area, the display resolution is low and the roads cannot be distinguished. In some cases, it is difficult to reliably touch the road intended by the user.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to reliably accept the setting of the road intended by the user with a simple operation when receiving the setting of the road via the touch panel. .

  In order to solve the above-described problems, the present invention sets a wide area for accepting a road (link) selection on the display screen.

  For example, the first aspect of the present invention is a navigation device having a touch panel on the front surface of a display device, and when a map display means for displaying a map on the display device and a touch on the touch panel are detected, A road extracting means for extracting a road near a position on the map corresponding to the touch position, and when the road extracting means extracts a plurality of roads, the map is displayed so that the extracted roads belong to different areas. When a touch on the touch panel is detected, a region belonging to the region to which the touch position belongs is set as the road selected by the user when a touch on the touch panel is detected. Road setting means.

According to a second aspect of the present invention, there is provided a navigation device having a touch panel on the front surface of the display device, wherein a map display means for displaying a map on the display device and a touch position when a touch on the touch panel is detected. When the road specifying means for specifying the road on the map corresponding to the road and the road specified by the road specifying means include lanes in directions different from each other, two display areas of the map are defined with the road as a boundary. When the touch on the touch panel is detected, the lane assigned to the area side to which the touch position belongs is specified, and the specified lane is selected by the user. Road setting means for setting as a road lane.

  An embodiment of the present invention will be described below with reference to the drawings.

  In the following embodiment, a case where a destination is set will be mainly described. However, the present invention is not limited to this, and the present invention can be applied to the case where a specific point such as a departure point or a waypoint is set by selecting a road.

  FIG. 1 is a schematic configuration diagram of an in-vehicle navigation device 1 to which an embodiment of the present invention is applied. As shown in the figure, the in-vehicle navigation device 1 includes a control device 10, a current position calculation device 20, an input device 30, and a display device 40.

  The current position calculation device 20 is a device for calculating the current position, and includes a vehicle speed sensor, a gyro sensor, a GPS (Global Positioning System) receiver, and the like.

  The input device 30 is a device for receiving an instruction from a user. The input device 30 includes a touch panel 31 that can be seen through a display screen provided on the front surface of the display device 40. In addition, you may provide the hard switch (not shown) separately.

  The display device 40 includes a liquid crystal display device and the like, and is a unit that displays graphics information generated by the control device 10.

  Returning to FIG. The control device 10 is a device for controlling other devices (current position calculation device 20, input device 30, display device 40, etc.). The control device 10 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an interface with other devices (current position calculation device 20, input device 30, display device 40, etc.), these It is constituted by a general-purpose computer system including a bus for connecting the two.

  The control device 10 includes a process execution unit 11, an input content analysis unit 12, a destination link setting unit 13, and a display processing unit 14 as functional units. These functional units are achieved by executing a program loaded into the memory by the CPU. Therefore, a program for performing each process is stored in the ROM.

  The process execution unit 11 is a central unit that performs various processes. For example, from the output of the current position calculation device 20, the current position is calculated by map matching processing using the map data 15 stored in the storage device. In addition, a user request is received via the input content analysis unit 12 and a process corresponding to the request is executed. Further, in response to a user's request, a transition is made to the destination setting mode, and a destination road (referred to as “destination link”) is set via the destination link setting unit 13. Then, a recommended route from the current position to the destination link is searched by the Dijkstra method or the like.

  The input content analysis unit 12 analyzes a request from the user input via the input device 30 and sends the result to the process execution unit 11.

  The destination link setting unit 13 sets a destination link. Specifically, designation of a facility that serves as a landmark such as a building or a park on the map is received from the user via the touch panel 31, and a destination is set based on the location of the facility. At this time, when a plurality of roads (links) exist in the vicinity of the designated facility, processing for specifying the destination road (destination link) is performed. In addition, when the designation of the road on the map is received from the user, in order to identify which lane is the destination by checking whether there is a lane with a different traveling direction on the designated road Perform the process.

  The display processing unit 14 performs processing for displaying a map and a menu on the display device 40. For example, a map near the current position is displayed based on the map data 15.

  The map data 15 stores map drawing data. Specifically, data relating to a link constituting a road on the map (link data 151) and data relating to a facility such as a building or a park arranged on the map (facility data 152) are stored.

  FIG. 2 is a diagram showing the configuration of the link data 151. As shown in FIG. The link data 151 stores link data included in each mesh area, which is a partitioned area on the map. That is, the link data 151 includes, in each record, a code (mesh ID) 1511 for identifying a mesh, a code (link ID) 1512 for identifying a link, coordinate positions 1513 of a start node and an end node of the link, and a link The type 1514 of the road to which the vehicle belongs is stored. The traveling direction is defined by the direction from the start node to the end node. That is, in the present embodiment, roads including up and down lanes are managed separately on the assumption that there are two links up and down.

  FIG. 3 is a diagram illustrating a configuration of the facility data 152. In the facility data 152, a mesh ID 1521 (corresponding to the mesh ID 1511), a code for identifying a facility (facility ID) 1522, a coordinate position 1523, and an icon 1524 used for display are stored in each record. ing.

  [Description of Operation] Next, the characteristic operation of the vehicle-mounted navigation device 1 of this embodiment will be described. Note that description of navigation processing such as route search and route guidance, which are the original basic operations, is omitted.

  The in-vehicle navigation device 1 according to the present embodiment accepts settings for destinations and waypoints via the touch panel 31.

  FIG. 4 is a flowchart of the destination setting process. 5 and 6 are screen transition diagrams during such processing. FIG. 5 shows a case where a facility on the map is touched, and FIG. 6 shows a case where a road on the map is touched.

  When the process execution unit 11 is requested by the user to shift to the destination setting mode via the input device 30, the process execution unit 11 instructs the destination link setting unit 13 to start the flow of FIG.

  The destination link setting unit 13 displays a map on the display screen 400 of the display device 40 via the display processing unit 14 as shown in FIGS. 5 (A) and 6 (A). Specifically, based on the position information (start node, end node 1513) of the link data 151, a link existing in the range of the map to be displayed is extracted, and a predetermined position on the corresponding map is determined in a predetermined drawing mode. The road 411 is displayed on the screen (see the road 411 in FIGS. 5 and 6). Further, based on the coordinate position 1523 of the facility data 152, the facility existing in the range of the map to be displayed is extracted, and the extracted facility icon 1524 is displayed at a predetermined position on the map corresponding to the coordinate position 1523 ( (See the facility icon 402 in FIGS. 5 and 6). When the destination setting unit 13 receives a map scroll request from the user via the input device 30, the destination setting unit 13 scrolls and displays the map according to the received request.

  The destination link setting unit 13 monitors the touch on the touch panel 31 from the user via the input content analysis unit 12 (S11). When a touch is detected (Y in S11), it is determined whether the touch position is on the facility icon 402 or on the road 411 (S12). If neither (N in S12), the process returns to S11 and continues.

  On the other hand, when the touch position is on the facility icon 402 or the road 411 (Y in S12), the destination link setting unit 13 extracts a link near the touch position (S13).

  Specifically, when the touch position is on the facility icon 402, the destination link setting unit 13 uses the facility reference point (the facility coordinate position 1523 stored in the facility data 152) as a reference. With reference to the link data 151, a link existing in a predetermined range (for example, within 50 m) is extracted. For example, as shown in FIG. 7, the vertical lines V1, V2, and V3 are dropped from the reference point P to the nearby links L1, L2, and L3, and the lengths of the vertical lines V1, V2, and V3 are within a predetermined distance (for example, 50 m )) Is extracted.

  On the other hand, as shown in FIG. 6B, when the road 411 is touched, the destination link setting unit 13 refers to the position information (start node, end node 1513) of the link data 151 and sets the touch position. Identify existing links. Here, as shown in FIG. 8, when there are lanes with different travel directions on the road 411 such as “up lane” and “down lane”, the link data 151 includes two links L4 with different travel directions. , L5 are stored. In such a case, the destination link setting unit 13 extracts the two links L4 and L5.

  On the other hand, when the road 411 has only a lane in the same direction, the link data 151 stores only one link corresponding to the road 411. In such a case, the destination link setting unit 13 extracts the one link.

  Once the links near the touch position are extracted in this way, the destination link setting unit 13 determines whether there are a plurality of extracted links (S14). When the number of extracted links is one (N in S14), the process proceeds to S18, where the destination link setting unit 13 sets the extracted link as the destination link, and ends the flow of FIG.

  On the other hand, when there are a plurality of extracted links (Y in S14), the destination link setting unit 13 displays an area dividing line on the map (S15).

  Hereinafter, the case where the facility icon 402 is touched and the case where the road 412 is touched will be described in detail.

  When the facility icon 402 is touched, the destination link setting unit 13 makes perpendicular lines V1, V2, V3 to the links L1, L2, L3 extracted in S13 from the reference point P of the facility icon 402 as shown in FIG. , And obtain a line 405 that bisects the angle between adjacent vertical lines V1, V2, and V3. These lines 405 are displayed on the map as boundary lines 405 that divide the map display area 401 as shown in FIG. In the example of FIG. 5C, the map display area 401 is divided into three areas Ar1, Ar2, and Ar3 by a boundary line 405.

  Furthermore, the destination link setting unit 13 assigns one link to one divided area. Specifically, for each link extracted in S13, the divided area to which the intersection of the perpendicular line from the reference point P belongs is specified, and the link is assigned to the specified divided area. In the example of FIG. 5C, links L1, L2, and L3 are allocated to the divided areas Ar1, Ar2, and Ar3, respectively.

  On the other hand, when the road 411 is touched in S11, the destination link setting unit 13 sets the center of the road 411 as a boundary line 412 as shown in FIG. Then, as shown in FIG. 6C, a boundary line 412 that divides the map display area 401 into two is displayed. In the example of FIG. 6C, the map display area 401 is divided into two areas Ar4 and Ar5 by a boundary line 412.

  Furthermore, the destination link setting unit 13 assigns one link to one divided area. Specifically, for each link, the side of which divided area exists is checked, and the link is allocated to the existing divided area. As in Japan, when the left lane is in the traveling direction, each link belongs to the left divided area in the traveling direction. In FIG. 6C, links L4 and L5 are allocated to the divided areas Ar4 and Ar5, respectively.

  When the divided areas are set in this way, the destination link setting unit 13 monitors the touch on the touch panel 31 via the input content analysis unit 12 (S16).

  When a touch is detected (Y in S16), the destination link setting unit 13 specifies a divided area to which the touch position belongs. Then, the link assigned in S15 is specified for the specified divided area (S17).

  In the example of FIG. 5, the destination link setting unit 13 specifies the link L3 when touched in the divided area Ar3. Further, in the example of FIG. 6, when touched in the divided area Ar5, the link L5 is specified.

  Then, the destination link setting unit 13 sets the identified link as the destination link (S18), and ends this flow. As shown in FIGS. 5D and 6D, destination icons 406 and 413 may be displayed at the position of the destination link so that the set destination link can be seen.

  The flow of the destination setting process shown in FIG. 4 has been described above.

  According to the above-described embodiment, first, after the user touches the approximate position of the link to be selected, it is checked whether there are a plurality of links in the vicinity thereof. When there are a plurality of links, touch areas for selecting any one of the links are provided with a sufficiently large area. Therefore, the user can select a target link without worrying about the delicate position of the touch position. That is, the target link can be surely selected by a rough touch operation.

  In addition, a fan-shaped divided area that radiates around the touch position is set. Therefore, the user can perform a touch operation in a sufficiently wide area while confirming the positional relationship of the target link with respect to the touch position.

  As described above, according to this embodiment, the user can be surely selected a target link by a simple operation.

  The present invention is not limited to the above embodiment. The above embodiment can be variously modified.

  For example, a boundary line for dividing the display area may be stored in the facility data 152 for each facility. A link ID of a nearby link may be assigned to each area divided by the boundary line.

  In this way, it is not necessary to calculate the boundary lines of the divided areas, and the memory consumption can be reduced. In addition, an appropriate link can be selected in consideration of the direction of the entrance and exit of the facility.

  For example, in facilities such as a stadium, there are a plurality of entrances, and the nearest links connecting to each entrance are different. In such a case, the facility data 152 stores a boundary line that divides the display area 401 by the number of links connected to the entrance. One of the links is assigned to each divided area. When the facility is touched, the destination link setting unit 13 refers to the facility data 152, displays the boundary line of the divided area, and waits for a touch operation from the user. When there is a touch operation, the facility data 152 is referenced to identify the link assigned to the divided area to which the touch position belongs, and the identified link is set as the destination link. In this way, even if there is a link that does not connect to the entrance near the stadium, only the link that connects to the entrance can be selected by the user.

  Further, the input content analysis unit 12 does not necessarily have to accept selection of the divided area via the touch panel, but may accept designation by another hard switch or voice input. For example, the input content analysis unit 12 sequentially moves the focus to the divided areas on the display screen via the display processing unit 14 according to the rotation of the dial switch. Then, the pressing of the confirm button is detected, and the divided area where the focus is placed at that time is confirmed as the divided area selected by the user.

  In addition, this invention is not limited to a vehicle-mounted navigation apparatus, It can apply to the information equipment which performs the process which receives selection of the spot on a map.
