  Embodiments of the present invention will be described below with reference to the accompanying drawings.

(Configuration of Example 1)
FIG. 1 is a block diagram illustrating the configuration of the navigation device according to the first embodiment. According to FIG. 1, the navigation device 1 according to the first embodiment includes a control unit 10, an operation unit 11, a GPS (Global Positioning System) reception unit 12, a storage unit 13, and a display unit 14. Composed.

  The operation unit 11 is a pointing device including a key switch, a mouse, and the like that are operated by a user to input data such as a destination and a search condition to the control unit 10. The GPS receiver 12 is a receiver that receives radio waves emitted from a plurality of GPS satellites and is used by the controller 10 to determine the current location of the host vehicle.

The storage unit 13 is a large-capacity storage device using a semiconductor memory, a magnetic disk, an optical disk or the like as a storage medium, and includes a map DB (131) storing map information, a facility DB (132) storing facility information, and the like. It is allocated and stored in a predetermined area. DB is an abbreviation for Data Base. The display unit 14 is a monitor including a display device such as an LCD (Liquid Crystal Display) or an OLED (Organic Electro-Luminescence Diode), and is generated by the control unit 10, for example, as shown in FIGS. 3, 4, and 5. Display screen information.

  The control unit 10 sets a route to the destination, displays conditions based on the set route on the screen of the display unit 14, and has a function of setting a waypoint based on the conditions displayed on the screen. This is the device body. For this reason, the control unit 10 includes a route setting unit 101, a search condition acquisition unit 102, and a display control unit 103.

  After setting the destination, the route setting unit 101 sets a waypoint based on the conditions displayed on the display unit 14. The search condition capturing unit 102 captures conditions input via the operation unit 11 and outputs them to the route setting unit 101. The display control unit 103 performs control for converting, for example, the set route output from the route setting unit 101 into display information and displaying it on the display unit 14.

(Operation of Example 1)
FIG. 2 is a flowchart illustrating the operation of the navigation device 1 according to the first embodiment. Hereinafter, the operation of the navigation device 1 according to the first embodiment shown in FIG. 1 will be described in detail with reference to the flowchart of FIG.

  First, it is assumed that an initial screen (menu) for navigation is displayed on the display unit 14 (step S101). Here, the user operates the operation unit 11 to select “route search” from the menu (“YES” in step S102), and as a result, the operation unit 11 is operated based on the guidance displayed on the display unit 14. And enter the destination. In response to this, the control unit 10 receives a plurality of routes (hereinafter referred to as candidate routes) whose destinations are the destinations that are input and imported from the current location measured by the route setting unit 101 based on the signal from the GPS receiving unit 12. For example, screen information (route display screen) shown in FIG. 3 is generated and output to the display control unit 103. The display control unit 103 converts the screen information output from the path setting unit 101 into display information matched with the display unit 14 and writes the display information in a VRAM (Video RAM) (not shown). The written display information is synchronized with the display timing. Read and display on the display unit 14 (step S103).

  Next, the user selects a route suitable for the purpose from the candidate routes displayed on the display unit 14 in consideration of the estimated arrival time, distance, fee, and the like. Here, it is assumed that the user selects, for example, the route A (hatched display on the route display screen in FIG. 3). Here, it is assumed that the user wants to drop in at a facility such as a restaurant located on the route A because the travel time has some margin and is also at lunch time. Here, the facilities located on the route A include not only facilities located along the route but also facilities located within a predetermined distance range from the route, for example, within a 1 km range. At this time, the user operates (presses) the “route point setting button” 140 assigned and displayed in the lower right of the route display screen shown in FIG. 3 (step S104 “YES”), as will be described later. The restaurant you want to stop by can be set as a stopover.

  That is, when the “route point setting button” 140 is operated, the screen displayed on the display unit 14 is changed from the route display screen of FIG. 3 to the route point search condition input screen of FIG. 4 (step S105). As a result, the user can display each condition item such as “passage point transit time”, “additional time”, “additional distance”, “facility genre”, “facility genre details”, etc. displayed as the search condition input screen of FIG. Appropriate data is selected from the input items pop-up displayed for each. Here, the “passage point transit time” refers to the time required to pass through the transit point from the current location, for example, selected from within 1 hour, after 1 to 2 hours, after 2 to 3 hours, and so on. Is possible. The “additional time” refers to a time added for passing through a transit point, and can be selected from 0 minutes, within 15 minutes, within 30 minutes,. “Additional distance” refers to a distance for passing through a transit point, and can be selected from, for example, 0 km, 1 km to 10 km, 11 km to 20 km,.

  The “facility genre” is a classification of facilities to be searched for in the vicinity, and can be selected from meals, sightseeing facilities, shopping, and so on. The “facility genre details” is details for each facility genre. For example, when a meal is selected as the “facility genre”, it can be selected from Japanese food, Western food,.

  When the user operates the operation unit 11 to sequentially input the waypoint search conditions and operates the “confirmation button” 141 assigned and displayed at the lower right of the screen (“YES” in step S106), the control unit 10, the search condition capturing unit 102 captures the input search condition and outputs it to the route setting unit 101. The route setting unit 101 refers to the map DB (131) and the facility DB (132) stored in the storage unit 13, and extracts a plurality of candidate routes corresponding to the input search condition. Subsequently, the route setting unit 101 generates, for example, a route selection screen illustrated in FIG. 5 based on the extracted candidate routes and displays the route selection screen on the display unit 14 via the display control unit 103. In the route selection screen of FIG. 5, candidate routes (here, routes a, b, and c) are displayed in ascending order of expected arrival time (additional time) calculated by the route setting unit 101 (step S107). .

  The user gives a mark to the check box 142 corresponding to the intended route from the route selection screen displayed on the display unit 14 in consideration of the new estimated arrival time, distance, fee, etc. Then, the “route selection button” 143 is operated (step S108 “YES”). As a result, a new route passing through the set waypoint is displayed on the display unit 14 so as to be superimposed on the map (step S109). In calculating the estimated arrival time (additional time T), for example, the route setting unit 101 obtains the additional time with the shortest distance T2 from the route T1 to the waypoint P as shown in FIG. As shown in FIG. 6B, there are two methods for obtaining the estimated arrival time T from the route T3 newly added via the waypoint P (T = T3-T1). Note that the candidate routes may be displayed in the order of increasing additional time, in the order closer to the current location, or in the order of “Aiueo” regardless of the estimated arrival time.

  Thereafter, the destination guidance guidance via the restaurant set as a waypoint is displayed by displaying a well-known route guidance screen (step S110), and the user goes to the destination via the facility set according to the guidance. You can drive towards.

(Effect of Example 1)
According to the navigation device 1 according to the first embodiment described above, the control unit 10 (route setting unit 101) sets the destination, and then based on the condition based on the set route displayed on the display unit 14. By setting the waypoint, for example, when there is a surplus in the arrival time to the destination, facilities that the user wants to visit, such as tourist spots and restaurants, can be automatically set as a waypoint. Convenience can be provided. In addition, when displaying the set route, the display unit 14 may superimpose and display only a specific facility on the route on the screen on which the map is displayed. As a result, the waypoint can be set manually.

  In the first embodiment described above, the navigation device 1 automatically performs the waypoint setting after the destination setting, but only the specific facility obtained by the facility search after the destination setting is superimposed on the map screen. The user can manually set the waypoint. This will be described in detail below as a second embodiment.

  In the second embodiment described below, the configuration shown in FIG. 1 is used as in the first embodiment. A series of processes from the destination setting to the “route point setting button” (140 in FIG. 3) operation is the same as the processing steps (S101 to S103) of the first embodiment shown in the flowchart of FIG. Hereinafter, description will be given focusing on the operation after step S104, which is a difference from the first embodiment.

  For example, it is assumed that the user wants to drop in at a specific facility such as a gas station (GS) on the way home from being set as a destination. At this time, the user sets and inputs the GS that he / she wants to stop according to the well-known facility search screen displayed after the operation of the “route place setting button” 140 in FIG. In response to this, the route setting unit 101 refers to the vehicle current location signal acquired from the GPS receiving unit 12 and the map DB (131) and facility DB (132) stored in the storage unit 13. Thus, a plurality of GS located in the traveling direction of the vehicle are extracted, and the extracted GS is output as a selection candidate to the display control unit 103 together with the map where the GS is located. Receiving this, the display control unit 103 superimposes the GS and the map information, and displays them on the display unit 14 as a waypoint setting screen.

  FIG. 7 is a diagram illustrating an example of a screen configuration of the waypoint setting screen displayed on the display unit 14. As shown in FIG. 7, GS that the user wants to drop in on the way home is superimposed and displayed on the map as a plurality of candidate transit points. The user confirms this waypoint setting screen and intuitively selects a GS to be set as a waypoint. The selection is performed by operating (pressing) the GS object itself displayed on the display unit 14 with the operation unit 11. Then, a guidance route is set by operating a “route selection button” 144 assigned and displayed at the lower right of the screen.

  Note that “selection by intuition” refers to an operation in which the user manually selects a transit point passing time, an additional distance for adding a transit point, and an item having the shortest additional distance for passing a transit point. Thereafter, a known route guidance screen is displayed, guidance to the home via the GS set as a waypoint is started, and the user travels to the destination including the specific facility set according to the guidance. . As shown by a broken line in FIG. 7, after running a plurality of candidate facilities, the candidate facilities are deleted from the screen of the display unit 14.

(Effect of Example 2)
According to the navigation device 1 according to the second embodiment, a route to a destination is set, and only a specific facility on the route is displayed superimposed on a screen on which a map is displayed. From the location of the specific facility above, it is possible to intuitively select and set a specific facility that suits the purpose, such as a transit point transit time, an additional time for adding a transit point, or a distance. In addition, since only the specific facility in the vehicle traveling direction is displayed on the waypoint setting screen, the display content is simplified, and economical traveling toward the destination together with the waypoint is possible.

  In the second embodiment, the user who confirms the waypoint setting screen on which the specific facility and the map information are superimposed is configured to set the waypoint by intuition. Conditions based on the route such as the additional time or the additional distance may be set in advance (default setting), and the navigation device 1 may automatically set the waypoint according to the default set conditions.
