  Next, the display on the display monitor 16 at the time of route guidance in the navigation device 1 according to the embodiment of the present invention will be described with reference to FIGS. In the following description, it is assumed that the display screen of the display monitor 16 displays a map in which the traveling direction of the vehicle is upward, that is, a heading-up map. As described above, the display screen of the display monitor 16 is approximately 1 DIN size. As shown in FIG. 3A, a map 20A around the vehicle position is displayed on the left screen 16a of the display monitor 16, and a map 20B continuous with the map 20A in the vehicle traveling direction is displayed on the right screen 16b. Has been. A vehicle position mark 21 is displayed at the current location of the vehicle on the map 20A, and a recommended route 22 that distinguishes the searched road from other roads is displayed on the maps 20A and 20B.

  When the maps 20A and 20B are displayed in a split screen, it is difficult to recognize the correspondence between the map 20A on the left screen 16a and the map 20B on the right screen 16b. Therefore, a bond mark 23 is displayed at the same position on the recommended route 22 in the maps 20A and 20B on the two screens 16a and 16b. The user can easily image one map 20C showing the vehicle periphery and the vehicle traveling direction as shown in FIG. 3B from two consecutive maps 20A and 20B using the bond mark 23 as a clue. can do.

  In the navigation device 1 according to the embodiment of the present invention, the map 20D around the position where the recommended route displayed on the map 20B in FIG. 4 (c)) can be displayed. With reference to FIG. 4, an operation for displaying the map 20 </ b> D around the position further advanced on the recommended route will be described.

  As shown in FIG. 4A, when the bond mark 23 displayed on the display monitor 16 is pressed, a distance input screen 30 shown in FIG. 4B is displayed on the display monitor 16. The input device 18 is operated to input a set distance (for example, 10 km) on the distance input screen 30 as shown in FIG. As a result, as shown in FIG. 4C, the right screen 16b displays a map 20D around the position where the vehicle has traveled the distance (10 km) input on the recommended route from the vehicle position.

  Next, map display processing in the embodiment of the present invention will be described with reference to the flowcharts of FIGS. 5 and 6 and FIGS. 7 and 8. The processing in FIGS. 5 and 6 is executed in the control circuit 11 by a program that starts when route guidance is started.

  In step S501, the current location of the vehicle is detected using the current location detection device 14. In step S502, based on the current location detected in step S501, a display range near the current location in the map data and a further forward display range are determined.

  With reference to Fig.7 (a), the process of step S502 is demonstrated. Reference numeral 40 indicates a map area around the map area displayed on the two screens of the display monitor 16, reference numeral 41 indicates the current location of the vehicle, and reference numeral 42 indicates a recommended route. Reference numeral 43a indicates a display range near the current location (map 20A in FIG. 3A), and reference numeral 43b indicates a further forward display range (map 20B in FIG. 3A). The display range 43a and the display range 43b are continuous and overlap in the region 43c. The display ranges 43a and 43b are uniformly determined by the current location 41 of the vehicle. Therefore, based on the current location detected in step S501, a display range near the current location in the map data and a further forward display range can be determined.

  In step S503, as shown in FIG. 7B, the map of the display range 43a is displayed on the left half 16a of the display screen, and the map of the display range 43b is displayed on the right half 16b of the display screen. In step S504, the bond mark 23 is displayed at a position on the recommended route 42 in an area 43c where the display range 43a near the current location and the display range 43b in front of the display range 43a overlap. 7C, the bond mark 23 is displayed at a position on the recommended route 42 in the area 43c in the map on the left screen 16a and the map on the right screen 16b.

  In step S505, based on the pressed position of the touch panel 19 calculated by the touch panel control unit 110, it is determined whether or not the bond mark 23 has been pressed. If the bond mark 23 is pressed, an affirmative determination is made in step S505, and the process proceeds to step S601 in FIG. If the bond mark 23 is not pressed, a negative determination is made in step S505, and the process returns to step S501.

  In step S601 in FIG. 6, the distance input screen 30 (FIG. 4B) is displayed on the display screen of the display monitor 16. In FIG. 3B, “10 km” is displayed on the distance input screen 30, but “OO km” is displayed in step S601. In step S <b> 602, based on the signal output from the input device 18, it is determined whether a set distance has been input to the distance input screen 30. When the set distance is input to the distance input screen 30, an affirmative determination is made in step S602, and the process proceeds to step S603. If the set distance is not input on the distance input screen 30, step S602 is repeated.

  In step S603, the current position detection device 14 is used to detect the current position of the vehicle. In step S604, as shown in FIG. 8A, the vehicle position (future vehicle position) 44 when traveling for a set distance set and input from the current location 41 along the recommended route 42 is calculated. In step S605, as shown in FIG. 8A, a display range 43a near the current location in the map area 40 and a display range 43d near the future vehicle position 44 are determined. As described above, the display range 43a is a predetermined size based on the current location 41 of the vehicle, and the display range 43d can also be determined as a predetermined size based on the future vehicle position 44. .

  In step S606, as shown in FIG. 8B, the map of the display range 43a is displayed on the left half 16a of the display screen, and the map of the display range 43d is displayed on the right half 16b of the display screen. In step S607, as shown in FIG. 8C, the bond mark 23 is displayed at a position on the recommended route 42 above the map 43a near the current location. The bond mark 23 is displayed at a predetermined distance from the own vehicle position 41 as in FIG.

  In step S608, based on the pressed position of the touch panel 19 calculated by the touch panel control unit 110, it is determined whether or not the bond mark 23 has been pressed. If the bond mark 23 is pressed, an affirmative determination is made in step S608 and the process returns to the start. If the bond mark is not pressed, a negative determination is made in step S608, and the process returns to step S603. Note that the transition from the screen of FIG. 8C to the screen of FIG. 3A may be performed by pressing a return button (not shown).
