<p>A map display for vehicle. The control circuit of the map display mounted on a vehicle divides the screen of a display device into a plurality of sections and converts bird's-eye view data into map picture data for every area. The control circuit then prepares vehicle information picture data used for displaying a mark indicating the present location of the vehicle and destination of the vehicle. When the destination is in the area displayed on the screen, the control circuit prepares the mark data so as to display the mark at the position corresponding to the destination. When the destination is out of the area, the control circuit prepares the mark data so as to display the mark at the position which is nearest to the destination in the direction toward the destination. When the map picture data and vehicle information picture data are prepared, the control circuit displays the picture data on the display and again detects the present location of the vehicle. When the distance that the vehicle has traveled does not exceed a prescribed value, the control circuit changes the display position of the vehicle position indicating mark. When the distance is larger than the prescribed value, the control circuit changes the map picture data. Grid line information for displaying bird's-eye views and Mercator's charts are stored in advance in a grid line information storing memory and the control circuit selects the grid line information corresponding to the picture display mode selected by the operator and superimposes the information upon a road map in displaying the road map.</p> |
