Abstract

See full text

In a navigation apparatus for a vehicle, after the present position of a vehicle is obtained, a position on a map which corresponds to the present position of the vehicle is obtained. Subsequently, the heading direction of the vehicle is detected. When the vehicle is traveling on the left-hand lane, coordinate conversion is performed such that a present position mark is shifted leftward from the center of the road by 1/4 of the road width. This makes it possible to display a route while preventing the route from overlapping with the centerline of the road. In another navigation apparatus for a vehicle, a structure-profiled map on which a structure-representing shape and a road are drawn is displayed so as to provide road guidance, wherein a route is displayed on the structure-profiled map along a road which is displayed for guidance. The display of the route is performed such that the route is shifted from the center line of a road toward a lane on which the vehicle is traveling. The route is displayed by using a pattern having a width corresponding to the width of the road in accordance with the lane of the road to be guided.
