  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Circuit Configuration of Navigation Device In FIG. 1, reference numeral 1 denotes an on-vehicle navigation device as a whole, and a CPU (Central Processing Unit) 2 controls the entire circuit through a bus 11, and a ROM ( The navigation program and the SA / PA guide display control function to be described later are executed by starting up the basic program stored in the Read Only Memory) 3 and the application program stored in the hard disk drive 7 on the RAM (Random Access Memory) 4. It is made to do.

  The navigation device 1 stores map data in the hard disk drive 7 and displays a map according to the map data on the screen of the display 6 in response to a request from the user, and a GPS (Global Positioning System) antenna 10 and The current position of the moving body is detected via the GPS module 9 and the gyro 8, and the traveling direction is specified, and the result is displayed on the map.

(2) SA / PA guide display processing procedure Next, in the navigation device 1, a service for the user to make a break plan out of various point information such as interchanges, junctions, service areas, and parking areas existing on the highway. An SA / PA guide display processing procedure for displaying only the area and the parking area on the display 6 in a state specialized as point information will be described with reference to the flowchart of FIG.

  The CPU 2 of the navigation device 1 executes the SA / PA guide display processing procedure on the map displayed on the display 6 in accordance with the navigation program having the SA / PA guide display control function activated from the hard disk drive 7. Enter from the start step of RT1 and move to next step SP1.

  In step SP1, the CPU 2 of the navigation device 1 determines whether or not the moving body on which the navigation device 1 is mounted is traveling on the highway by using the GPS antenna 10 and the GPS module 9 from a GPS satellite (not shown). When it is determined that the vehicle is traveling on a general road, the process returns to step SP1, and when it is determined that the vehicle is traveling on a highway, the process proceeds to the next step SP2.

  When the CPU 2 of the navigation device 1 recognizes that the vehicle is traveling on the highway in step SP2, it starts counting the traveling time by starting counting the internal clock from that point, and moves to the next step SP3.

  In step SP3, the CPU 2 of the navigation device 1 determines whether or not the user is currently set to the SA / PA guide display mode via the input operation unit 5, and if a negative result is obtained, the SA / PA guide is determined in step SP3. Wait until the display mode is set.

  On the other hand, if the CPU 2 of the navigation device 1 is currently set to the SA / PA guide display mode, the CPU 2 obtains a positive result and proceeds to the next step SP4.

  In step SP4, the CPU 2 of the navigation device 1 detects the current vehicle position of the moving body via the GPS antenna 10 and the GPS module 9, and specifies the traveling direction of the moving body at the present time via the gyro 8, The process proceeds to step SP5.

  In step SP5, the CPU 2 of the navigation device 1 searches and extracts only the service area and the parking area from the point information such as the interchange, junction, service area, and parking area existing ahead of the moving body in the current traveling direction. The process moves to the next step SP6.

  In step SP6, the CPU 2 of the navigation device 1 determines whether or not there is a branch on the highway ahead of the current traveling direction of the moving object on the map. If there is no branch, the process proceeds to step SP8. Then, the process proceeds to the next step SP7.

  In step SP7, if there is a branch on the highway ahead in the direction of travel, the CPU 2 of the navigation device 1 searches and extracts only the point information of the service area and the parking area existing on both routes after the branch, The process proceeds to next step SP8.

  In step SP8, the CPU 2 of the navigation device 1 displays only the spot information of the service area and the parking area existing ahead in the traveling direction extracted in step SP5 or step SP7 on the display 6, and proceeds to the next step SP9.

  Specifically, as shown in FIG. 3, the CPU 2 of the navigation device 1 displays a triangular moving body icon 20 indicating a moving body on the screen of the display 6 so as to be superimposed on the path 21 and moves forward in the traveling direction. For example, a PA icon 22 indicating a Kohoku parking area, an SA icon 23 indicating an Ebina service area, and a PA icon 24 indicating a Nakai parking area are displayed at a time.

  As described above, when the SA / PA guide display mode is set by the user, the navigation device 1 has the Yokohama Machida Interchange between the Kohoku parking area and the Ebina service area ahead of the traveling direction, and the Ebina service area and the Nakai Although there are the Atsugi interchange and Sagano Nakai interchange between the parking area, these interchanges are not displayed but are displayed exclusively for the service area and the parking area.

  At this time, the CPU 2 of the navigation device 1 makes the distance 7.4 [Km] from the current vehicle position of the moving body to the Kohoku parking area, the required time 6 minutes, Ebina, with respect to the PA icons 22, 24 and the SA icon 23. The distance to the service area is 24 [Km] and the required time is 20 minutes, and the distance to the Nakai parking area is 49 [Km] and the required time is 40 minutes as travel schedule information. It can be used as a guide for users.

  Further, the CPU 2 of the navigation device 1 displays the facility information display fields 22A, 24A and 23A for the PA icons 22, 24 and the SA icon 23, respectively, thereby "restaurant" and "resting place". Information on facility congestion in the service area and parking area such as “gasoline” and “mixed” and “empty” parking lots obtained from the Vehicle Information and Communication System (VICS) In addition, it can be used as a guide when making a break plan for the user.

  Further, as shown in FIG. 4, when there is a branch on the highway ahead in the traveling direction, the CPU 2 of the navigation device 1 branches following the PA icon 24 indicating the Nakai parking area existing in the route 21 before the branch. The SA icon 25 indicating the Ashigara service area and the PA icon 26 indicating the Serizawa parking area that are present on both the subsequent routes 21A and 21B are displayed on the display 6.

  Also in this case, for the PA icons 24 and 26 and the SA icon 25, the distance from the current vehicle position of the moving body to the Nakai parking area is 7.4 [Km], the required time is 2 minutes, and the distance to the Ashigara service area. 29 [Km] and the required time of 22 minutes, the distance to the Serizawa parking area 20 [Km] and the required time of 15 minutes are displayed as travel schedule information, and the facility information and the information via the facility information display fields 24A, 26A and 25A, respectively. The parking lot congestion state is also displayed, which can be used as a guideline for the user to make a break plan.

  In step SP9, the CPU 2 of the navigation device 1 determines whether or not the route guidance mode for guiding the user to the desired destination is set. If the route guidance mode is set, the process proceeds to the next step SP10. If the route guidance mode is not set, the process proceeds to step SP11.

  In step SP10, the CPU 2 of the navigation device 1 provides route guidance by displaying the route 21 displayed on the screen of the display 6 in red, for example, and proceeds to the next step SP11.

  For example, as shown in FIG. 5, the CPU 2 of the navigation device 1 displays the route 21 with a red route line RTL (shown with diagonal lines), and an interchange of the exit that should be exited from the expressway to the general road in order to aim at the destination. Route guidance is performed by indicating (exit “Yokohama Machida”) by an arrow 30.

  At this time, the CPU 2 of the navigation apparatus 1 simultaneously displays the SA icon 25 indicating the Ashigara service area existing before the exit interchange (exit “Yokohama Machida”).

  This allows the user to take a break in the Nakai parking area where there are only “restaurants” and “rest areas” by visually checking the SA icon 25 indicating the Ashigara service area that exists before the exit interchange. Rather than getting off the expressway, there are facilities related to “restaurants”, “rest areas” and “gasoline”, and after taking a break in the Ashigara service area that is not crowded, get off the expressway and go to the destination You can also choose to head.

  At this time, the CPU 2 of the navigation device 1 displays the PA icon 24 of the Nakai parking area existing on the route line RTL at, for example, red (indicated by diagonal lines), and the foothold existing on the route 21 deviating from the route line RTL. By displaying the SA icon 25 of the service area in, for example, normal blue, the user can clearly distinguish the meaning of the PA icon 24 and the SA icon 25.

  Incidentally, as shown in FIG. 6, the CPU 2 of the navigation device 1 determines whether the route 21 </ b> A or the route 21 </ b> B is the route line RTL subject to route guidance when the route 21 is branched. The route line RTL is explicitly displayed by overlapping it.

  As a result, even if the PA icons 24 and 26 and the SA icon 25 corresponding to a plurality of service areas and parking areas are displayed, the user can check the spot information existing in the current traveling direction by the SA icon 25. Can be intuitively recognized.

  In step SP11, the CPU 2 of the navigation device 1 passes a certain time or more when the travel time started counting in step SP2 is the next service area or parking area, or the scheduled time when the next next service area or parking area elapses. When it is predicted that the predetermined time or more has not elapsed, the process returns to step SP10 to continue the route guidance, and when it is predicted that the predetermined time or more has elapsed, the next step SP12 is performed. Move on.

  In step SP12, the CPU 2 of the navigation device 1 performs a guide for prompting a break in accordance with a service area and a parking area where a certain time or more is expected to have elapsed since the user started traveling on the expressway. The process proceeds to SP13 and the process is terminated.

  In this case, as shown in FIG. 7, the CPU 2 of the navigation device 1 displays the SA icon 25 on the route line RTL in order to prompt the user to take a break in the Ashigara service area indicated by the SA icon 25 existing on the route line RTL. In addition to the arrow 31, the text “Let's take a break” is displayed.

  As a result, the CPU 2 of the navigation apparatus 1 makes the user aware that he / she has been continuously driving on the highway for a long time and prompts the user to take a break.

  Incidentally, at this time, the CPU 2 of the navigation device 1 determines the congestion status based on the “mixed” or “empty” status in the facility information display column 24A of the PA icon 24 and the facility information display column 25A of the SA icon 25, A break is urged in the Ashigara service area of the SA icon 25 on which “Empty” is displayed.

  Thus, even when the user goes to the Ashigara service area of the SA icon 25 in accordance with the instruction of the navigation device 1, the user will not fall into a situation where the parking lot is crowded and cannot be rested.

(3) Operation and Effect In the above configuration, when the SA / PA guide display mode is set by the user, the CPU 2 of the navigation device 1 is configured to store a plurality of pieces of point information existing forward in the traveling direction from the vehicle position of the moving body. Only the service area and the parking area are searched and extracted, and only the PA icons 22, 24, 26 and the SA icons 23, 25 are displayed on the display 6.

  Further, the CPU 2 of the navigation device 1 specializes the spot information to be displayed on the display 6 in the service area and the parking area, and when the route 21 is branched, the service area and the parking that exist in the branched routes 21A and 21B. Each area is also displayed, and the route line RTL for performing the guidance route is displayed in red, so that the user can select any service area or parking area and easily make a break plan, and the current progress The direction route can be recognized intuitively.

  Further, the CPU 2 of the navigation apparatus 1 indicates the exit interchange to be exited to reach the destination by an arrow 30 and also displays the service area and parking area that exist beyond the interchange. If so, it is not limited to the service area or parking area just before the exit where the break plan should be made, but the service area or parking area existing beyond the exit can also be included in the break plan Therefore, the choice of the break plan object with respect to a user can be increased.

  Further, the CPU 2 of the navigation device 1 measures the traveling time of the highway by the user, identifies a service area or parking area where the traveling time is assumed to exceed a certain time, and identifies the identified service area Alternatively, a break can be prompted with arrow 31 to cause a break in the parking area.

  As described above, the CPU 2 of the navigation device 1 displays only the point information specialized for the service area and the parking area on the display 6 for the user who is planning to take a break plan, and is meaningful using the point information. Route guidance can be performed.

  According to the above configuration, the CPU 2 of the navigation device 1 can intuitively and easily make a comfortable and safe break plan for the user driving the highway through the display screen of the display 6. .
