The images are displayed on the display means 4 through the drawing means 3-7 while being thinned out according to the rotation angle. That is, first, major intersections on the route are determined according to the processing means shown in FIG. 4(d),
Information such as the intersection information and the destination of the intersecting road is registered in a table, points on the route where the direction of travel changes significantly are calculated, the distances between these registered points are calculated, and these distances are displayed on the display means 4. If the distance is less than three times the display resolution, it cannot be displayed clearly, so all data is checked with a thinning mark attached to it, and only the registered data without a thinning mark is displayed. Next, the sketching means 3-5 displays the magnetic north according to the rotation angle and the scale based on the scale ratio.

The current position mapping means 3-4 converts these coordinates into display position coordinates using the mapping parameters, and displays the current position (see mark ■ in FIG. 6) including the traveling direction on the schematic diagram displayed on the display means 4. do. At the same time, the distance calculation means 3-3 calculates the travel distance from the starting point to the current location and the distance from the current location to the destination, and displays them on a schematic diagram on the display means 4 via the drawing means 3-7. (See Figure 6)
In the above embodiment, the route selection means 3-6 automatically selects the route, but the driver uses the operation means 2 to select the route from the map data storage means 5 to the display means 4 through the route selection means 3-6. You can display a map on the screen and input the desired route and current location.This way, the driver can select the most suitable route, and the functions of each means of the device are reduced, so the device's efficiency is reduced accordingly. Cost can be reduced.

(Effects of the Invention) According to the present invention, a schematic diagram including a route from a departure point to a destination is displayed on a display, furthermore, intersections at which to turn on the route are clearly indicated, and current position, direction of travel,
The driving distance from the departure point and the distance to the destination are displayed on the map, so there is no need to check every intersection on a detailed map or worry about the distance while driving. You can drive with confidence just by looking at the display when you get near an intersection. Further, since necessary information is extracted from a detailed map and displayed in a schematic form on the display, a display with a low resolution can be used, and the cost of the device can be reduced.
