A bird's eye view commonly used in a flight simulation is applicable to an apparatus and method for navigating a vehicle running on a set route of travel to a set destination using a (color) display unit according to the present invention. The bird's eye view of a road map surrounding a present position of the vehicle has a viewing point placed at a predetermined position on an upper sky in a direction opposite to the set destination with the present position of the vehicle as a reference and has a line of sight looking down over the road map so that a part of the road map surrounding the present position of the vehicle can be viewed in an extended scale form and the remaining part of the road map remote from the present position and nearer to the set destination can be viewed in a gradually reduction scale form.

[ What is claimed is:] [1.] An apparatus for navigating a vehicle using a display unit, comprising:a) road map storing means for storing a road map data related to a road map, the road map data including road network image data and character data related to the road map;b) vehicle position detecting means for detecting a present position of the vehicle;c) vehicle destination setting means through which a destination the vehicle is desired to reach is set on the road map;d) start point setting means for setting a start point of location on the road map at which the vehicle is to start on the basis of the detected position of the vehicle;e) route of travel setting means for setting a route of travel on the road map from the start point to the set destination; andf) display control means for controlling an image of the road map surrounding the set route of travel which is displayed on the display unit in a form of a bird's eye view such that the bird's eye as a viewing point is referenced at a predetermined position on a raised plane from said road map and offset in a direction opposite to the set destination with respect to the present position of the vehicle being displayed to appear to a user as looking down over the road map from the bird's eye, said road network image data being displayed on the display unit in a perspective view from the bird's eye view image of the road map and the character data being displayed on the display unit as plane data at a constant size regardless of a position of the displayed image screen on the display unit with respect to the present position of the vehicle.
