-First embodiment-
A configuration of a navigation apparatus according to an embodiment of the present invention is shown in FIG. This navigation device is mounted on a vehicle and used to display a map on a touch panel display monitor, set the point touched on the map as a destination, and recommend from the vehicle position to the destination. Search for a route. At this time, the road traced by the user on the map is included in the recommended route. The navigation device 1 shown in FIG. 1 includes a control circuit 11, a ROM 12, a RAM 13, a current location detection device 14, an image memory 15, a display monitor 16, an input device 17, and a disk drive 18. The disc drive 18 is loaded with a DVD-ROM 19 in which map data is recorded.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various processes and controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. Based on the map data recorded on the DVD-ROM 19, the control circuit 11 performs processing such as displaying a map and searching for a recommended route to a set destination.

  The current location detection device 14 is a device that detects the current location of the host vehicle. For example, a vibration gyro 14a that detects the traveling direction of the host vehicle, a vehicle speed sensor 14b that detects a vehicle speed, and a GPS sensor that detects a GPS signal from a GPS satellite. 14c and the like. The navigation device 1 can determine a route search start point when searching for a recommended route based on the current location of the host vehicle detected by the current location detection device 14.

  The image memory 15 temporarily stores image data to be displayed on the display monitor 16. The image data includes road map drawing data for displaying a road map, various graphic data, and the like, and is created by the control circuit 11 based on the map data recorded on the DVD-ROM 19. Various images such as a map image are displayed on the display monitor 16 using the image data stored in the image memory 15.

  A touch panel 16a is combined with the display monitor 16, and when any position on the display monitor 16 is touched by a user's finger or the like, information indicating the touch position is output from the touch panel 16a to the control circuit 11. . Based on the touch position information, the control circuit 11 determines which part of the image displayed on the display monitor 16 is touched at that time. The navigation device 1 according to the present embodiment performs various processes according to touch panel operations from the user detected by the touch panel 16a and the control circuit 11.

  The input device 17 is for accepting various operation inputs from the user, and is realized by an operation panel, a remote controller, or the like. For example, the input device 17 performs an operation such as an instruction for a map scroll direction and a change in map scale. These operations can also be performed by the touch panel operation described above. Therefore, the input device 17 is not essential in the navigation device 1 of the present embodiment, and may not be provided.

  The disk drive 18 reads map data for displaying a road map from the loaded DVD-ROM 19. This map data represents route calculation data used for route search to the destination, route guidance data used to guide the vehicle to the destination according to the recommended route, such as intersection name and road name, and roads Includes road data. The map data also includes background data representing map shapes other than roads such as rivers, railways, various facilities on the map (landmarks), and the like.

  In the road data, the minimum unit representing a road section is called a link, and each road is composed of a plurality of links. A point connecting the links is called a node, and each node has position information (coordinate information). The link shape, that is, the shape of the road is determined based on the position information of the node. Although an example using a DVD-ROM is described here, the map data may be read from a recording medium other than the DVD-ROM, such as a CD-ROM or a hard disk.

  When the point designated by the touch panel operation from the user is set as the destination, the navigation device 1 uses the current location detected by the current location detection device 14 as a route search start point, based on the above-described route calculation data. A route search from the current location to the destination is performed by calculating the algorithm. The recommended route obtained as a result of the route search is displayed on the road map separately from other roads by changing its display form, for example, display color. Thus, the user can recognize the recommended route on the road map displayed on the display monitor 16. In addition, the navigation device 1 guides the host vehicle by instructing the traveling direction by an image or voice to the user so that the host vehicle can travel according to the recommended route. Thus, route guidance to the destination is performed by displaying the road map and guiding the vehicle to the destination according to the recommended route.

  In the navigation device 1 of the present embodiment, when the destination is set and the recommended route is searched as described above, any road on the map displayed on the display monitor 16 is operated by the user's touch panel operation. When traced, the road is set as part of the recommended route. Thereby, the user can include an arbitrary road in the recommended route. This point will be described below with reference to FIGS. 2 and 3.

  FIG. 2 shows an example of the map image displayed on the display monitor 16 when the recommended route has not been searched yet. In the image of FIG. 2, when the user moves the finger or the like along the arrow indicated by reference numeral 21 from the vehicle position 20 while touching the display monitor 16 with the finger or the like, the touch panel operation is performed by the touch panel 16 a and the control circuit 11. Detected. Then, based on the detected locus of the touch position of the user in the touch panel operation, it is determined which road in the displayed map has been traced by the user. In accordance with the determination result, as shown in FIG. 3, the traced road is set as a part of the recommended route 22 and displayed with a bold line. At this time, the destination has not been set yet, so the recommended route 22 is set only halfway.

  After setting a part of the recommended route as described above, the user next sets the destination. At this time, in the navigation device 1 of the present embodiment, a specific area for searching for facilities is set on the map based on the user's touch panel operation, and the facilities in the area are searched and displayed in a list. Then, the facility selected by the user from the displayed list is set as the destination. In this way, even in an area such as an urban area where various facilities are densely packed, the user can accurately specify a facility that the user wants to set as a destination from among the densely packed facilities. This point will be described below with reference to FIGS.

  FIG. 4 shows a state in which the user continues to touch one point on the map displayed on the display monitor 16 after a part of the recommended route 22 is set by the user's touch panel operation as described above. Show. When a predetermined time elapses in this state, as shown in FIG. 5, a circular area 30 is displayed around the touched point.

  If the predetermined time further elapses as it is, the circular area 30 is displayed wider than that in FIG. 5 as shown in FIG. After that, when a predetermined time elapses from the state of FIG. 6, the circular area 30 is further expanded and displayed as shown in FIG. As described above, when the user continues to touch one point on the map, a circular area centered on the touch point is gradually enlarged and displayed according to the touch time. It should be noted that the enlarged display may be stopped when the circular area has a predetermined size or when reaching the edge of the screen.

  In the state shown in FIG. 7, when the user removes the finger or the like that has been touched until then from the display monitor 16, a list screen as shown in FIG. On this list screen, the names of facilities located in the circular area 30 of FIG. When the user selects one of the facility names displayed in the list, a recommended route with the facility as the destination is searched.

  For example, when “C station” at the third position in the list 40 is selected, the C station indicated by reference numeral 41 in FIG. 9 is set as the destination, and the recommended route 22 that has been set only halfway until then is set. The continuation is searched. As a result, the entire recommended route 22 from the vehicle position 20 to the station C is searched and displayed on the map with a bold line. As described above, the facilities in the area set in accordance with the user's touch panel operation are displayed as a list, and the facility selected by the user from the list is set as the destination.

  FIG. 10 shows a flowchart for executing the processing described above. This flowchart is executed in the control circuit 11 of the navigation device 1. In step S10, it is determined whether or not there has been a touch panel operation from the user. When the touch panel operation is detected, the process proceeds to the next step S20.

  In step S20, it is determined whether or not the touch position is stationary in the touch panel operation detected in step S10. When the touch position is stationary and does not change, that is, when it is detected that one point on the map displayed on the display monitor 16 is continuously touched, the process proceeds to step S30. In the following description, such a touch panel operation is referred to as a stationary touch operation. On the other hand, if the touch panel operation detected in step S10 is not a static touch operation and the touch position has changed, it is determined that any road on the map has been traced and the process proceeds to step S21.

  When the process proceeds from step S20 to S21, in step S21, it is determined which road is traced by the touch panel operation detected in step S10, and the road is set as a part of the recommended route. If step S21 is performed, it will return to step S10.

  When the process proceeds from step S20 to S30, a timer for measuring time (referred to as timer 1) is started in step S30. Here, by starting the timer 1, measurement of the duration when the user continues to touch one point on the map is started. In the next step S40, it is determined whether or not the finger of the user who performs the touch panel operation has left the touch panel. That is, it is determined in step S40 whether or not the stationary touch operation detected in step S20 is continued. When the user's finger or the like leaves the touch panel and the stationary touch operation is interrupted, the process proceeds to step S41. On the other hand, when the user's finger or the like has not left the touch panel and the stationary touch operation is continued, the process proceeds to step S50.

  In step S41, a point on the map corresponding to the touch position of the stationary touch operation detected in step S20 is set as the destination. If step S41 is performed, it will progress to step S160. On the other hand, in step S50, it is determined whether or not a predetermined time has elapsed since the timer 1 was started in step S30. When a predetermined time, for example, 1 second has elapsed, the process proceeds to the next step S60. If the predetermined time has not elapsed, the process returns to step S40.

  In step S60, a circular area as indicated by reference numeral 30 in FIG. 5 is displayed on the display monitor 16 around the touch position of the stationary touch operation detected in step S20. At this time, the radius of the circular region 30 is set to a predetermined size. In the next step S70, a timer for measuring time (referred to as timer 2) different from the timer 1 described above is started. Here, by starting the timer 2, the measurement of the elapsed time after displaying the circular area 30 is started.

  In step S80, as in step S40, it is determined whether or not the finger or the like of the user performing the touch panel operation has left the touch panel, that is, whether or not the stationary touch operation detected in step S20 is continued at this time. . If the user's finger or the like has left the touch panel and the stationary touch operation is interrupted, the process proceeds to step S110. On the other hand, if the user's finger or the like has not yet left the touch panel and the still touch operation is continued at this point, the process proceeds to step S90.

  In step S90, it is determined whether or not a predetermined time has elapsed since the timer 2 was started in step S70. The predetermined time at this time may be the same as or different from the time in the determination in step S50 described above. If the predetermined time has elapsed, the process proceeds to step S100, and if not, the process returns to step S80.

  In step S100, the circular area displayed in step S60 is enlarged and displayed on the display monitor 16 as indicated by reference numeral 30 in FIG. If step S100 is performed, it will return to step S70, and after resetting the timer 2, it starts again in step S70 and repeats said process. In this way, by repeating the processes in steps S70 to S100 until the user's finger leaves the touch panel, the circular area displayed in step S60 is gradually enlarged and displayed every predetermined time. As described above, when the circular area has a predetermined size, or when it reaches the end of the screen, the processing of steps S70 to S100 is stopped at that time, and the process proceeds to step S110. Good.

  When it is determined in step S80 that the stationary touch operation has been interrupted and the process proceeds to step S110, a facility search area for searching for facilities to be displayed in a list is set in step S110. This facility search area is set based on the user's touch panel operation. Specifically, the circular area enlarged and displayed in step S100 executed last is set as the facility search area. If Step S100 has never been executed, the circular area displayed in Step S60 is set as the facility search area.

  In step S120, the facility located in the facility search area set in step S110 is searched in the map displayed on the display monitor 16 based on the map data recorded in the DVD-ROM 19. In the next step S130, the names of the facilities searched in step S120 are displayed as a list as indicated by reference numeral 40 in FIG. At this time, information other than the facility name, for example, the facility genre may be included in the list and displayed.

  In step S140, it is determined whether any of the facilities displayed in the list in step S130 has been selected. If any of the facilities is selected, the process proceeds to step S150. In step S150, the facility is set as the destination facility.

  In step S160, the recommended route to the destination facility set in step S150 or the destination set in step S41 is searched. At this time, if a part of the recommended route is set in step S21, the recommended route including the destination to the destination is searched. When the recommended route is searched in step S160, the flowchart of FIG. As described above, the recommended route to the destination designated by the user's touch panel operation is searched.

According to the embodiment described above, the following operational effects can be obtained.
(1) Based on the user's touch panel operation, the facility search area is set on the map displayed on the display monitor 16 (step S110), and the facility located in the set facility search area is searched in the map. (Step S120), the searched facilities are displayed in a list (Step S130). Of the facilities displayed in this way, the facility selected by the user is set as the destination (step S150), and the recommended route to the destination is searched (step S160). In this way, in a navigation device that searches for a recommended route to the destination touched on the map by the user, it is difficult to accurately touch the facility that the user wants to set as the destination on the map. , You can set the destination correctly.

(2) One of the roads in the map displayed on the display monitor 16 is set as a part of the recommended route by judging the road traced based on the locus of the touch position of the user in the touch panel operation (step S21). In step S160, a search is made for a recommended route that includes a part of the recommended route set in this manner and reaches the destination. Since it did in this way, arbitrary roads which a user desires can be included in a recommended route.

(3) A predetermined circular area is displayed around the touch position of the user in the touch panel operation on the display monitor 16 (step S60). Thereafter, when the touch position is stationary, the circular area displayed in step S60 is gradually enlarged and displayed on the display monitor 16 (step S100). In this way, the facility search area is set in step S110 based on the circular area displayed in step S60 or the circular area enlarged in step S100. Since it did in this way, a user can set a facility search area | region by simple operation.

  In the above embodiment, when the user continues to touch a point on the map displayed on the display monitor 16, a circular area centered on the point is gradually enlarged and displayed. However, other shapes such as an ellipse or a rectangle may be gradually enlarged. Furthermore, an area may be set within a certain range from the road, and the area may be gradually enlarged along the road.

  FIGS. 14, 15 and 16 show how the area set within a certain range from the road is gradually enlarged along the road. When the user continues to touch one point on the map displayed on the display monitor 16, an area 31 shown in FIG. 14 is first set within a certain width from the road centering on the user's touch point. When a predetermined time elapses, the area 31 is enlarged along the road without changing the width from the road, as shown in FIG. When a predetermined time further elapses, the region 31 is further enlarged along the road as shown in FIG. Such an area 31 may be displayed instead of the circular area 30 shown in FIGS. 5 to 7 and the names of facilities located therein may be displayed as a list.

  In the above embodiment, the example of applying the area search method for displaying a list of facilities on a map has been described for the method for setting an area in accordance with a user's touch panel operation. It may be used for any purpose. That is, on the map displayed on the display monitor, a predetermined area is set around a point corresponding to the touch position of the user in the touch panel operation, and the area is gradually enlarged when the touch position is stationary This setting method may be used for any purpose.

-Second Embodiment-
A second embodiment of the present invention will be described. In the first embodiment described above, the area is gradually enlarged by continuously touching one point on the map displayed on the display monitor 16 and included in the area when the finger is released. The facility was listed. On the other hand, in this embodiment, the facilities included in the area traced by the user on the map displayed on the display monitor 16 are displayed as a list. This point will be described in detail below.

  Similar to the first embodiment, when a road is traced by a user's touch panel operation on the map displayed on the display monitor 16 as shown in FIG. 2, the road is shown in FIG. Set to part. When the user then removes his / her finger from the touch panel, a screen as shown in FIG. 11 is displayed in the present embodiment. On this screen, a mode switching button 50 is displayed, and the mode switching button 50 allows the user to select between “drawing navigation mode” and “facility search mode”.

  When “drawing navigation mode” is selected by the mode switching button 50, the road traced by the user's touch panel operation is set as a part of the recommended route. On the other hand, when the “facility search mode” is selected, the mode is shifted to a mode for accepting an area specifying operation from the user. In this mode, when the user traces a trajectory as indicated by reference numeral 51 in FIG. 12 on the map by a touch panel operation, the facilities included in the area surrounded by the trajectory are displayed in a list. As a result, a list screen as shown in FIG. 8 is displayed. The facility selected from this list is set as the destination facility as in the first embodiment, and a recommended route to the destination facility is searched.

  FIG. 13 shows a flowchart in the second embodiment described above. This flowchart is executed in the control circuit 11 of the navigation device 1 as in the first embodiment. In step S210, it is determined whether there has been a touch panel operation from the user. When the touch panel operation is detected, the process proceeds to the next step S220.

  In step S220, as in step S21 of FIG. 10, it is determined which road was traced by the touch panel operation detected in step S210, and the road is set as a part of the recommended route. In the next step S230, it is determined whether or not the finger of the user who performs the touch panel operation has left the touch panel. If the user's finger leaves the touch panel and the touch panel operation is interrupted, the process proceeds to step S240. On the other hand, when the touch panel operation is continued, the process returns to step S220.

  In step S240, a mode switching button as indicated by reference numeral 50 in FIG. 11 is displayed. In step S250, it is determined which one of the “drawing navigation mode” button and the “facility search mode” button is pressed by the user in the mode switching button. If the “drawing navigation mode” button is pressed, the process returns to step S220, and the above-described processing is repeated. If the “facility search mode” button is pressed, the process proceeds to step S260.

  In step S260, an area designation operation is received from the user. In the next step S270, it is determined whether or not an area designation operation is input from the user in step S260. When an area designation operation is input, that is, when a locus as indicated by reference numeral 51 in FIG. 12 is traced on the map by the user's touch panel operation, the process proceeds to step S280. If the area designation operation is not input, the process returns to step S260, and step S260 is continuously executed until the area designation operation is input.

  From steps S280 to S330, the same processing as steps S110 to S160 in FIG. 10 is executed. That is, in step S280, based on the region designation operation input in step S270, the region surrounded by the locus traced on the map by the user's touch panel operation is set as the facility search region. The facilities included in the facility search area are searched in step S290, and a list is displayed in step S300. Then, it is determined in step S310 whether any facility has been selected from the list, the selected facility is set as a destination facility in step S320, and a search is made in recommended route step S330 to that destination facility. As described above, the recommended route to the destination designated by the user's touch panel operation is searched.

According to the second embodiment described above, the following functions and effects can be obtained in addition to the functions and effects similar to those of the first embodiment.
