  In recent years, with the spread of automobiles and the development of electronic technology, in-vehicle navigation devices that are installed in vehicles and perform route guidance are rapidly spreading. The navigation device calculates and sets the route to the specified destination based on information such as roads and various facilities, and detects the location of the vehicle using GPS, etc., and displays a map or vehicle location screen along the route. The route is guided by display or the like.

  In such a navigation device, a route to the destination is calculated using weights such as time, distance, and toll according to the designation of the destination by the user, and a plurality of route candidates are calculated for the user from the calculation result. It is common to present.

  Further, when the user determines a guide route and the navigation apparatus performs guidance guidance according to the guide route, if the guide route includes a section of a route that the user does not want, in other words, the user passes If the point or road you want is not included in the route, for example, from the list information (registration point list information or search list information) to include the point or road that the user wants to go through only that section It is proposed that a navigation device re-searches a guidance route based on the added or changed point and processes the route so as to include a route desired by the user.

Further, in providing a route to the user, the user searches for the route with an intuitive operation by accepting an input of the starting point or the current position and the destination using a touch panel type input means from the user. A navigation device that can handle this has also been proposed (see Patent Document 1).

Note that the basic functions of the vehicle position detection unit 30, the destination reception unit 31, the route calculation unit 32, the guide unit 38, and the display control unit 39 are not elements unique to the present invention, but perform a navigation process common to the conventional one. Therefore, explanations other than those notable in this embodiment will be omitted in some cases.

[2. Effect)
[2-1. Overview of processing
An overview of the processing of this embodiment will be described. First, when the user designates a destination through the input unit 12, the destination receiving unit 31 receives the destination, and based on this, the route calculation unit 32, like the conventional navigation device, straight line priority, back road priority, paid Based on conditions specified by the user such as road priority, general road priority, road width priority, etc., an optimum route to the destination is calculated, displayed on the display unit 7 via the display control unit 39, and displayed on the guide unit 38. Performs route guidance to the user by screen display and voice output.

  In the normal route guidance screen shown in FIG. 3, when the route to which the user is guided does not include a desired route or waypoint, in other words, when the route section that the user wants to pass is not included, A desired route section is directly designated on the guide route via the touch panel of the display unit 7 provided as the input unit 12. Specifically, the input from the user is obtained via the touch panel for the start point, end point, and waypoint of the midway route, and the route including the start point and end point including the waypoint is re-searched based on this. The changed route section that is recalculated by the user's designation is called an intermediate route.

[2-2. (Start point determination process)
The above operation will be specifically described with reference to the flowchart of FIG. 2 in the order of determination of the start point, determination of the end point, and determination of the waypoint. First, regarding the determination of the start point, the start point of the route section that the user wants to change is specified via the input unit 12 from the touch panel configured as the display unit 7 as shown in FIG. Then, the screen touch detection unit 33 detects this (YES in S1) and inputs it to the midway route start point detection unit 34 together with the designated position information on the screen (S2). The midway route start point detection unit 34 detects the position coordinates on the specified map based on the position information from the screen touch detection unit 33 (S3), and uses the midpoint route calculation as a start point for recalculation as a midway route. Input to the unit 37 (S4). Thereby, the start point determination process is terminated (S6).

  When determining the start point of the midway route in the midway route start point detection unit 34, as shown in FIG. 4, when the coordinates of the start point are detected based on designation from the user in the input unit 12, the display unit By displaying the “research start point” button on the screen of FIG. 7, the fact that this button has been pressed (YES in S 5) is set as the start point determination condition, the end point determination process end condition and the end point determination process It can also be a start condition.

[2-3. (End point determination process)
Next, the user inputs the end point of the route on the way. Specifically, as shown in FIG. 5, the end point of the route section that the user wants to change is specified via the input unit 12 on the touch panel. Then, the screen touch detection unit 33 detects this (YES in S7) and inputs it along with the designated position information on the screen to the midway route end point detection unit (S8). The midway route end point detection unit 35 detects the position coordinates on the specified map based on the position information from the screen touch detection unit 33 (S9), and uses the midpoint route calculation as an end point for recalculation as a midway route. Input to the unit 37 (S10).

  When determining the end point of the midway route in the midway route end point detection unit 35, as shown in FIG. 6, when the coordinates of the end point are detected based on the designation from the user in the input unit 12, the display unit 7 By displaying the “research end point” button on the screen (YES in S11), the fact that this button has been pressed is set as the condition for determining the end point, and as the start condition for the waypoint determination process as the next process. It is also possible to ask the user for confirmation (S12). Thereby, the end point determination process is completed.

  As shown in FIG. 5 and FIG. 6, after the end point is determined, when the user is requested to input the end point, a guidance “Start point has been set. Please set the end point” is displayed. For the convenience of the user, pressing this button can be used as the end condition of the end point determination process and the start condition of the waypoint determination process.

[2-4. (Via-point determination process)
After the start point and the end point are determined, a via point located between the start point and the end point is determined based on the user input. This point is shown using FIG. 7 and FIG.

  As shown in FIG. 7, the waypoint is determined by specifying the waypoint of the route section that the user wants to change via the input unit 12 on the touch panel. Then, the screen touch detection unit 33 detects this (YES in S13), and inputs it along with the designated position information on the screen to the intermediate route detection unit (S14). The midway route stop detection unit detects the position coordinates on the specified map based on the position information from the screen touch detection unit 33 (S15), and inputs it to the midway route calculation unit 37 as a waypoint (S16). ).

  Here, the determination of the waypoint is different from the start point determination process or the end point determination process, and the user does not designate a point on the route. Therefore, in the waypoint determination process, unlike the above two processes, the user touches a point on the current route instead of simply touching and specifying a desired position as a waypoint to the user. Thus, the screen touch detection unit 33 detects this and inputs it to the waypoint detection unit 36. Then, as shown in FIG. 8, the waypoint detection unit 36 displays a route section connecting the start point and the end point as a drag state display based on the input from the screen touch detection unit 33 and displays the display control unit 39 and the display. Display from part 7.

  When the user moves while touching the waypoint candidate on the touch panel of the display unit 7, that is, drags, the screen touch detection unit 33 detects this and detects the position information on the screen of the waypoint candidate to be moved. Input continues to the detector 36. When the screen touch detection unit 33 detects that the user stops dragging on the touch panel and leaves the touch panel, the waypoint detection unit 36 detects the position based on the position information input from the screen touch detection unit 33 at that time. Detect coordinates on the map.

  At this time, whether or not the user has removed a finger or the like from the touch panel is determined by the screen touch detection unit 33 not detecting input from the touch panel for a predetermined time (eg, arbitrarily set time such as 0.3 seconds). It is made on the basis of that. Further, the waypoint detection unit 36 determines the position as a waypoint (S18), and inputs this position information to the midway route calculation unit 37. Thereby, the waypoint determination process is terminated.

  In this waypoint determination process, as shown in FIG. 8, for example, a button “Drag and drop and set a waypoint” is displayed on the screen of the display unit 7 to determine the waypoint of the user. Processing may be prompted. Further, as described above, at the time when the user removes his / her finger from the touch panel and this is detected, that is, when the waypoint is determined, for example, as shown in FIG. While displaying a route that connects the end point and the end point with a straight line on the map as a simple guide route, a button “Re-search at set point” is displayed on the screen of the display unit 7, and this button is pressed, In addition to the end condition of the waypoint determination process, it can also be set as the start condition of the reroute calculation process described later (S17).

[2-5. (Reroute calculation process)
The midway route calculation unit 37 executes route calculation including the waypoint between the start point and the end point based on the position information of the start point, the end point, and the way point determined by the above three processes (S19). As a result, the route that the user desires and the route that has passed through the route are re-searched and re-searched by means such as the display unit 7 via the guide unit 38 and the display control unit 39 as shown in FIG. Guide guidance is made based on the halfway route (S20).

[2-6. effect〕
According to the present embodiment as described above, when the point or road that the user wants to pass through is not included in the route, the user designates the start point, the end point, and the waypoint by operating the touch panel, It becomes possible to recalculate the route on the way including the intended waypoint. As a result, the user can easily and quickly perform a re-search of a predetermined section by changing the waypoint in the route through a visual operation.

  In the above-described aspect, when a user input to a point on the route is detected during guidance guidance between the determined start point and end point, the guide route portion between them is displayed as a drag state on the display unit. Thus, the user can know about the route connecting the start point and the end point and the waypoint, and can determine the waypoint while visually considering the route.

  When determining the start point, end point, and waypoint of this route, press the button by displaying buttons such as “Re-search start point”, “Re-search end point”, and “Re-search at set point” on the screen. By using as a condition for determining the start point, end point, and waypoint, it is possible to ask the user to confirm the operation, and convenience is enhanced.
