The navigation device 1 determines a display range of the map, 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 as a vehicle position mark on the map.

  The image memory 15 stores image data to be displayed on the display monitor 16. This image data includes road map drawing data and various graphic data, which are appropriately generated based on the map data stored in the DVD-ROM 113. The navigation device 1 can perform map display and the like by using the image data generated in this way.

  The disk drive 112 reads map data from the DVD-ROM 113. The map data includes map display data, route search data, and the like. The map display data and the route search data include road link information and node information stored in the map data. 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 a user request. The map data includes facility data (facility data) displayed on the map. The facility data includes longitude / latitude coordinates of each facility, address, name, type, business hours, text data describing detailed information of the facility, and the like. The map data may be read from a recording medium other than the DVD-ROM 113, such as a CD-ROM or a hard disk.

  The display monitor 16 provides the user with various information such as a map near the vehicle position as a screen display based on various information such as map data. The speaker 17 outputs sound for instructing the user to perform various input operations and for guiding the route. The input device 18 has operation keys for the user to set various commands, and is realized by a button switch on the operation panel, a hard switch around the panel, or the like.

  When the destination is set by the user, the navigation device 1 performs a route calculation from the current location detected by the current location detection device 14 to the destination based on a predetermined algorithm. In the following, 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 user can recognize the recommended route on the map on the screen. Further, the navigation device 1 instructs the user 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.

  The satellite radio receiver 111 receives a satellite radio broadcast broadcast from a satellite radio station (not shown) via an artificial satellite and outputs it to the control circuit 11. Information included in the satellite radio broadcast (hereinafter referred to as satellite radio information) will be described with reference to FIG. The satellite radio information 20 includes not only audio programs such as news programs 21a, music programs 21b, and sports programs 21c, but also data information such as traffic information 21d and facility information 21e.

  The traffic information 21d includes information related to traffic jams, road construction, and the like, and link information of locations where the traffic jams, road construction, etc. are occurring. The navigation device 1 can acquire the traffic information 21d from the satellite radio information 20, and can display information on the traffic jam or road construction on the monitor 16 superimposed on the map.

  The facility information 21e includes facility information to be displayed on the display monitor 16 in the same manner as the facility data included in the map data of the DVD-ROM 113. The facility information 21e is facility information acquired by the satellite radio station, and is facility information about some of the facilities stored in the DVD-ROM 113. The facility information 21e includes the longitude / latitude coordinates 23a, address 23b, name 23c, type 23d, business hours 23e, text data 23f describing the detailed information of the facility, highlight flag 23g, information update date 23h, and the like. It is. The highlight flag 23g is a flag for instructing to display the facility mark on the display monitor 16 in a highlighted manner. Therefore, the facility mark is highlighted for the facility for which the facility information 21e is acquired from the satellite radio information 20. For example, as shown in FIG. 2, since the information of “ABC gas station” 23 is included in the facility information 21e, when “ABC gas station” is displayed, “ABC gas station” is highlighted. Since the facility information 21e is updated when the satellite radio station acquires new information, the facility information 21e is always the latest information. Therefore, the user can determine the facility from which the latest information is acquired by using the highlight display as a mark.

  Next, the facility mark display process in the embodiment of the present invention will be described with reference to FIGS. A description will be given assuming that the facility mark of the gas station among the facility marks is selected by the user and displayed on the map. FIG. 3 is a diagram showing a map around the vehicle position. The display monitor 16 displays a vehicle position mark 31 and gas station facility marks 32 a to 32 f superimposed on the map 30. Among the gas stations where the facility marks 32a to 32f are displayed, the facility marks 32a to 32e are highlighted because the facility information is acquired from the satellite radio information for the gas stations of the facility marks 32a to 32e. The highlighting is performed by displaying the outlines of the facility marks 32a to 32e dark and thick. Furthermore, among the highlighted facility marks 32a to 32e, the facility marks 32a to 32d that are close to each other are displayed as follows. That is, as shown in FIG. 3, it is displayed in a three-dimensional manner, extending in a direction that does not overlap the other facility marks 32a to 32d. On the other hand, the facility mark 32e is not highlighted since the facility information is not acquired from the satellite radio information for the gas station with the facility mark 32f.

  The facility marks 32a to 32f serve as buttons for displaying detailed information on the facility. For example, as shown in FIG. 4A, when the facility mark 32b is pressed, detailed information of “ABC gas station” corresponding to the facility mark 32b is displayed as a pop-up screen 41 as shown in FIG. 4B. The As described above, the facility marks 32a to 32d in which the facility marks 32a to 32d are close to each other are displayed in a direction that does not overlap the other facility marks 32a to 32d. Therefore, as shown in FIG. 4A, even if the facility marks 32a to 32d are densely packed, the facility marks 32a, 32c, and 32d of other facilities are not accidentally pressed, and the desired facility mark is displayed. 32b can be pressed. On the other hand, as shown in FIG. 5, when the facility marks 32a to 32d are not expanded and displayed, small facility marks are displayed densely. Therefore, if the display screen is pressed so as to press the facility mark 32b, there is a high possibility that the other facility marks 32a, 32c, and 32d will be pressed by mistake.

  Next, the facility mark display process in the embodiment of the present invention will be described with reference to the flowchart of FIG. The processing in FIG. 6 is executed in the control circuit 11 by a program that starts when a map is displayed on the display monitor 16.

  In step S601, a satellite radio broadcast is received from the satellite radio receiver 111. In step S602, facility information is acquired from satellite radio information. In step S603, the acquired facility information is collated with facility data stored in the DVD-ROM 113. Thereby, it is possible to recognize which facility mark should be highlighted among the facility marks displayed on the display monitor 16. In step S604, among the facility marks displayed on the display monitor 16, the facility mark is highlighted for the facility having the highlight flag 23g.

  In step S605, it is determined whether there is a facility mark in which facility marks are close to each other within a predetermined distance. Facility marks that are approaching within a predetermined distance include overlapping facility marks. If there is a facility mark approaching within a predetermined distance, an affirmative determination is made in step S605, and the process proceeds to step S606. If there is no facility mark approaching within the predetermined distance, a negative determination is made in step S605, and the facility mark enlargement process ends. In step S606, the position of the center of gravity of the position of the facility where the facility mark is approaching is calculated. For example, when the positions of the three facilities are (X1, Y1), (X2, Y2), (X3, Y3), the positions of the centers of gravity of the three facilities are ((X1 + X2 + X3) / 3, (Y1 + Y2 + Y3) / 3 ) In step S607, the facility mark that is approaching is displayed three-dimensionally like a building in a direction away from each other with the position of the center of gravity as the center.

The navigation device 1 according to the above-described embodiment of the present invention has the following operational effects.
(1) The facility marks 32a to 32d that are close to the other facility marks 32a to 32d are extended and displayed in a direction that does not overlap the other facility marks 32a to 32d. Accordingly, even if the facility marks 32a to 32d are close to each other, desired facility marks 32a to 32d can be easily selected by a finger pressing operation.

(2) When the facility marks 32a to 32d are expanded and displayed, the facility marks 32a to 32d are three-dimensionally displayed. If the facility marks 32a to 32d are simply extended and displayed on the map 30, the display of the long facility marks 32a to 32d is uncomfortable. However, when displayed three-dimensionally, the facility mark looks like a building, and even if the facility marks 32a to 32d are extended and displayed on the map 30, they do not feel strange.

(3) The facility marks 32a to 32e are highlighted for the facility for which information is acquired from the satellite radio information. Therefore, the user can easily determine the facility from which the latest information is acquired from the satellite radio information by using the highlighting as a mark.

The above embodiment can be modified as follows.
(1) Of the facility marks 32a to 32e of the facility that acquired the facility information 21e from the satellite radio information 20, only the facility mark 32e that is not close to other facility marks is highlighted. However, the facility mark 32e may be enlarged and displayed as shown in FIG. The facility in which the latest facility information 21e is acquired from the satellite radio information 20 can be more easily identified. Moreover, it becomes easy to press the facility mark 32e.

(2) If the facility marks 32a to 32d adjacent to the other facility marks 32a to 32d are expanded in a direction that does not overlap the other facility marks 32a to 32d, the facility marks are not limited to those that are expanded and expanded. . For example, as shown in FIG. 8, the facility marks 32a to 32d may be expanded in the direction of the arrow. Also in this case, the desired facility marks 32a to 32d can be easily selected from among the facility marks 32a to 32d that are densely displayed by a finger pressing operation.

(3) When the facility marks 32a to 32f are pressed, the detailed information of the facility corresponding to the pressed facility marks 32a to 32f is displayed, but the facility corresponding to the pressed facility marks 32a to 32f is searched for the route search destination. You may make it set as. Even if the facility marks 32a to 32d come close to each other, it is possible to prevent the user from accidentally pressing the other facility marks 32a to 32d and set the other facilities as the destination.

(4) As for the facility marks 32a to 32d of the facility for which the facility information 21e is acquired from the satellite radio information 20, the facility information 91a to 91d may be displayed together with the facility marks 32a to 32d as shown in FIG. As a result, it is easy to determine the facility where the latest information is acquired from the satellite radio information 20. Further, when the display range of the facility information 91b is pressed, the processing defined in the facility mark 32b related to the facility information 91b may be executed. Since the facility information 91a to 91d is displayed larger than the facility marks 32a to 32d, the desired facility mark 32b can be easily selected by a finger pressing operation. For the facility marks 32a to 32d adjacent to the other facility marks 32a to 32d, the facility information 91a to 91d is displayed in a direction not overlapping with the facility information 91a to 91d of the other facility marks 32a to 32d. Thereby, even if it adjoins to the other facility marks 32a-32d, the desired facility mark 32b can be easily selected by the pressing operation of the finger.

(5) Not only when the map 30 around the vehicle position is displayed, but also when the map 30 is displayed by scrolling the map 30, when displaying a facility mark adjacent to another facility mark, the facility mark is close You may make it expand in the direction which does not overlap with other facility marks. FIG. 10 shows a map 30 displayed by scrolling the map 30 by pressing the scroll buttons 33a to 33d. The map 30 is scrolled in the vertical and horizontal directions by the pressed scroll buttons 33a to 33d. When displaying the facility marks 32a to 32d adjacent to the other facility marks 32a to 32d, the facility marks 32a to 32d are enlarged in a direction not overlapping the adjacent facility marks 32a to 32d. In this case as well, even if the facility marks 32a to 32d are close to each other, the desired facility marks 32a to 32d can be easily selected by a finger pressing operation.

(6) Not only the facility that received the facility information 21e from the satellite radio broadcast, but the facility that paid the advertising fee may be highlighted. There is a high possibility that the facility marks 32a to 32e that are highlighted are pressed by the facility mark 32f that is not highlighted and detailed information is displayed. Therefore, the advertising effect can be expected by highlighting the facility mark. Further, the size of the facility mark may be determined according to the paid advertisement fee. This is because the larger the facility mark is, the higher the possibility that it is pressed and detailed information is displayed.

(7) The facility mark to be enlarged is not limited to the facility mark of the gas station. For example, a facility mark of a movie theater may be used. As detailed information of the facility mark of the movie theater, the title, fee, screening time, etc. of the movie being shown are displayed.

(8) The facility information 21e may be received and acquired from the information center through a network in addition to receiving and acquiring satellite radio broadcasts.

(9) The highlighting is performed by displaying the outlines of the facility marks 32a to 32e dark and thick. However, if the facility marks 32a to 32e of the facility for which the facility information 21e is acquired from the satellite radio broadcast are displayed prominently than the facility mark 31f of the facility for which the facility information 21e is not acquired from the satellite radio broadcast The form is not limited. For example, the display color of the facility marks 32a to 32e of the facility that has acquired the facility information 21e from the satellite radio broadcast is changed so as to be more conspicuous than the display color of the facility mark of the facility that has not acquired the facility information 21e from the satellite radio broadcast. May be.
