Abstract
The vehicular navigation system of the present invention includes a present position detector for detecting the present position of a vehicle, an input device for inputting a destination, an information memory for storing road data for searching for an optimal route, a route search system for searching for an optimal route to the destination based on the road data stored in the information memory, a route information converter for converting the route information near the present position of the vehicle to a visually 3-dimensional route information based on configuration of the road by the route search system, and a display for outputting and displaying the route information converted by the route information converter. The present position of the vehicle is detected, and the present position of the vehicle and route information ahead of the present position can be easily confirmed by detecting the present position of the vehicle and by converting the route information of the present position, based on the configuration of the road, to a 3-dimensional road display.
