  Next, the operation of the present invention will be described.

  First, the operation at the time of navigation of the navigation device 10 will be described, and then the operation when the server device 34 is accessed to obtain information will be described.

  When an engine (not shown) of the vehicle 1 is started, supply of power to the navigation device 10 is started. When the supply of power is started, the CPU 11 inputs position information (for example, information indicating latitude and longitude) supplied from the GPS receiver 17 and detects the current position of the vehicle. Next, the CPU 11 acquires setting information (illustrated) set by the user in the past from the HDD 13 and extracts the set map display scale. For example, when 100 m is selected as the display scale, map information in a predetermined range centered on the vehicle position supplied from the GPS receiver 17 (map information in a wider range than the range displayed on the LCD 16). Is acquired from the map information DB 13 a and stored in the video memory 15. At this time, the facility information included in the range of the acquired map information is also acquired from the facility information DB 13b and stored in the video memory 15 as well.

  Next, of the map information stored in the video memory 15, the CPU 11 instructs the graphic processor 12 to execute a drawing process on map information and facility information belonging to a range (display range) displayed on the LCD 16. And give instructions. As a result, information as shown in FIG. 4 is displayed on the LCD 16.

  As shown in FIG. 4, the LCD 16 has a display unit 16a, and the touch panel 22 is arranged on the display unit 16a so as to press an icon or the like displayed on the display unit 16a with a finger. Thus, it is possible to input predetermined information corresponding to the icon. Buttons 20a to 20f are arranged around the display unit 16a. A triangular icon 70 indicating the vehicle position is displayed at the center of the display unit 16a. In addition, an icon 71 indicating an orientation, an icon 71 indicating a scale, and an icon 73 operated when displaying a home page are displayed on the upper left of the display unit 16a. In addition, the display unit 16a displays character strings “Restaurant XX”, “XX movie theater”, “XX apartment”, and “XX parking lot” drawn based on the facility information. In addition, it is also possible to display the icon which modeled each facility instead of a character string.

  By referring to such information, the user can know the position of the vehicle on the map and the state of the surrounding road, and can also know the route to the destination. When the input device 20 is operated and a predetermined destination is input, the CPU 11 searches for a route from the current location to the destination and presents it to the user, and navigates based on the route selected by the user. Execute. That is, the CPU 11 clearly indicates the route on the map and instructs the traveling direction by voice so that the host vehicle travels along the selected route.

  Next, an operation when accessing the server device 34 will be described. FIG. 5 is a flowchart for explaining the operation when the navigation device 10 according to the embodiment of the present invention accesses the server device 34. The process shown in this flowchart is executed based on the control program 13c shown in FIG. 2, and is executed when the icon 73 shown in FIG. 4 is operated. The icon 73 is an icon that is operated when accessing a homepage related to a predetermined facility on the map displayed on the display unit 16a of the LCD 16, and a predetermined part of the map is pressed after the icon 73 is operated. In the case of a failure, access is made to the homepage corresponding to the part. When the flowchart shown in FIG. 5 is started, the following steps are executed.

  Step S10: The CPU 11 refers to the output signal from the touch panel 22 to determine whether or not a predetermined part has been pressed. If it has been pressed, the process proceeds to step S11. Otherwise, the same processing is performed. repeat. For example, in FIG. 4, when a portion where the character string “◯ × parking lot” is displayed on the display unit 16 a is pressed, the process proceeds to step S <b> 11.

  Step S11: The CPU 11 refers to the output of the touch panel 22 and acquires position information indicating the position of the map corresponding to the portion pressed by the user. Specifically, the CPU 11 refers to the output of the touch panel 22 and acquires position information (latitude and longitude) of the map corresponding to the coordinate information of the part pressed by the user. For example, in the case where the portion where the character string “XX parking lot” is displayed in FIG. 4 is pressed, the coordinate information of the touch panel 22 and the map information are collated to check the location information of XX parking lot. (Latitude and longitude) is obtained.

  Step S12: The CPU 11 refers to the position information acquired in step S11 and specifies the instructed facility information. Specifically, the CPU 11 refers to the position information acquired in step S11, and displays information regarding facilities existing within a predetermined range (for example, within a circle with a radius of 20 m) from the position indicated by the position information. Search from the memory 15. As a result, for example, in FIG. 4, when the portion where the character string “◯ × parking lot” is displayed is pressed, the facility information regarding ◯ × parking lot is acquired. It is also possible to search directly from the facility information DB 13b of the HDD 13 without developing it in the video memory 15.

  FIG. 6 is a diagram illustrating an example of facility information. As shown in this figure, the facility information 50 includes a facility name 51, a type 52, an address 53, a telephone number 54, a position 55, and a URL 56. Here, the facility name 51 is information indicating the name of the facility (for example, a store name or the like). The type 52 is information indicating the type of facility (for example, a restaurant, a movie theater, a parking lot, a sightseeing spot, etc.). The address 53 is information indicating an address that is the location of the facility. The telephone number 54 is information indicating a telephone number for contacting the facility. The position 55 is information indicating information (latitude and longitude) indicating the position of the facility. The URL 56 as access information is information for accessing a homepage established by the facility on the server device 34.

  In the process of step S12, the CPU 11 searches for a facility existing within a predetermined range from the pressed part on the map with reference to the position 55 of each facility, and identifies the corresponding facility. When there are a plurality of corresponding facilities, these can be displayed in a list and can be selected by the user.

  Step S13: The CPU 11 acquires the URL 56 included in the facility information 50 specified in step S12. For example, in FIG. 4, when a portion where the character string “◯ × parking lot” is displayed is pressed, “http: //www.○×.co.jp” is acquired as the URL.

  Step S14: The CPU 11 controls the communication device 21 to access the resource indicated by the URL acquired in step S13. Specifically, the CPU 11 controls the communication device 21 to call the access point 32 and set a communication line with the access point 32. Then, the communication device 21 starts communication using an IP (Internet Protocol) address assigned from the access point 32.

  Step S15: The CPU 11 controls the communication device 21 to download desired information from the server device 34. For example, in FIG. 4, when the portion where the character string “Ox Parking” is pressed, the resource indicated by the URL “http://www.Ox.co.jp” is accessed. And “index.html” which is an HTML (Hyper Text Markup Language) document stored in the resource is downloaded.

  Step S16: The CPU 11 determines whether there is a sufficient area for displaying a frame for displaying the acquired information around the portion of the display unit 16a pressed in step S10, and determines that it exists. If so, the process proceeds to step S18. Otherwise, the process proceeds to step S17. For example, as shown in FIG. 4, when the pressed parking lot is located at the end of the display unit 16a, there is a sufficient area on the left side, and the process proceeds to step S18. As shown in FIG. 7, when the pressed parking lot is located at the center of the display unit 16a, there is not a sufficient area around it, and the process proceeds to step S17.

  Step S17: The CPU 11 instructs the graphic processor 12 to scroll the map in a predetermined direction. For example, in the example shown in FIG. 7, since there is no sufficient display area around the pressed part, for example, the map is scrolled to the left and moved to the position shown in FIG. In the example of this figure, since the entire map is scrolling to the right, the triangle icon 70 indicating the vehicle position is also moved to the right side of the display unit 16a. Instead of scrolling (moving and displaying the map sequentially), the map in the target range may be directly displayed.

  Step S18: The CPU 11 controls the graphic processor 12 to display a frame (details will be described later with reference to FIG. 9) for displaying information around the pressed portion.

  Step S19: The CPU 11 controls the graphic processor 12, and displays the information downloaded in step S15 inside the frame displayed in step S18.

  FIG. 9 is an example of information displayed on the display unit 16a of the LCD 16 at this time. In this example, a frame 80 extended in a form that blows out from a parking lot is displayed, and information relating to the parking lot is displayed inside. Specifically, the title of the homepage “○ × parking lot” is displayed in the upper part of the frame 80, and the character strings “access”, “fee”, “regular holiday”, “parking” are displayed on the left side of the frame 80. "Limitation" and "Full vehicle information" are displayed. Here, “access” is linked with information indicating a method of accessing the XX parking lot. “Fare” is linked to information indicating the charge of XX parking lot. “Regular holiday” is linked to information indicating a regular holiday of XX parking lot. “Parking restrictions” is linked to information indicating parking restrictions (for example, maximum vehicle height, maximum vehicle width, etc.) in a parking lot. “Full vehicle information” is linked with information indicating the current full state of the parking lot. When these underlined character strings are pressed, the corresponding information is downloaded and the display information in the frame 80 is updated.

  Step S20: The CPU 11 determines whether or not an instruction to end the display is given. If the instruction is given, the process proceeds to step S21, and otherwise the same process is repeated. Specifically, for example, when a portion of the frame 80 shown in FIG. 8 to which no link is attached is pressed, it is determined that the end of display has been instructed, and the process proceeds to step S21.

  Step S21: When the map is scrolled in step S17, the CPU 11 controls the graphic processor 12 to restore the map to the original position. For example, in the state of FIG. 8, the map information is moved in the left direction so that the vehicle position is located at the center of the display unit 16a.

  According to the above processing, when the map is pressed, the corresponding facility information is specified, the URL stored in the facility information is referred to, and the information stored in the server device 34 is downloaded. Since the information is displayed, various information can be obtained quickly by simply pressing the information displayed on the map.

  Moreover, since the URL is included in the facility information, it is possible to obtain not only information posted on the home page indicated by the URL but also information such as a telephone number and an address. If displayed on a part of the display unit 16a, even if the homepage specified by the URL has disappeared, the information can be obtained directly by contacting the store.

  In addition, since both the pressed part of the map and the frame 80 are displayed on the display unit 16a, it is possible to refer to the information described on the homepage while referring to the information about the surroundings of the facility. become.

  Next, a second embodiment of the present invention will be described.
