Land vehicle navigation apparatus
First Claim
1. Land vehicle navigation apparatus comprising:
- means for calculating a desired navigational route for a vehicle, via fixed road paths, between a start location and a desired destination location;
means for determining desired vehicle maneuvers at predetermined road locations along said navigation route, anddisplay means coupled to said vehicle maneuver determining means for receiving vehicle maneuver information therefrom and for visually displaying to a driver of the vehicle on a display screen said desired vehicle maneuvers to be implemented at said predetermined road locations,wherein the improvement comprises said maneuver determining means providing data to said display means such that said display means indicates said desired vehicle maneuvers by providing a visual arrow graphic representation;
wherein said means for determining said desired vehicle maneuvers at said predetermined road locations also includes means for providing data indicating the distance of additional vehicle travel which must be implemented prior to the execution of said calculated desired vehicle maneuver, and wherein said additional distance travel data is visually displayed on said display means as an effective bar graph which is superimposed on and displayed within and without touching boundaries of said visually displayed arrow graphic representation.

Abstract
A land vehicle navigation apparatus (10) has a vehicle navigation computer (11) which determines a navigation route and provides vehicle maneuver visual displays on a CRT display (13). The displays are preferably provided in the form of graphic arrow representations (26, 28) which are illustrated in perspective form with a tail of the arrow (26B, 28B) shown in the foreground and towards to the bottom of a display screen (20) and the head of the arrow (26A, 28A) shown in the background. A visual display of an effective bar graph, indicating the additional distance to be traveled prior to execution of the visually displayed vehicle maneuver, is visually provided and superimposed on the visually displayed vehicle maneuver graphic arrow. The bar graph comprises a series of stack horizontal bars (27, 29) superimposed on the arrow (26, 28) which is preferably shown in three dimensional form. This type of visual display more readily communicates to the vehicle operator the type of vehicle maneuver to be implemented and the time at which it is to be implemented, while utilizing a minimum amount of display space and requiring minimal distraction of the vehicle driver from his view of the road.
