Land vehicle navigation apparatus with visual display
First Claim
1. Land vehicle navigation apparatus with visual display comprising:
- means for calculating a desired navigation route for a vehicle, via fixed road paths, between a start location and a desired destination location;
means for determining estimated current position of the vehicle;
wherein the improvement comprises,display means for visually displaying to said vehicle operator in one color at least a portion of said calculated navigation route, which displayed portion includes a plurality of different road path intersections, on a road map display along with displaying, on said road map display in a second contrasting color, actual vehicle travel as a displayed travel path between a predetermined point on said road map display to a position on said road map display corresponding to said estimated current vehicle position.

Abstract
Land vehicle navigation apparatus (10) with a visual display (16, 20) is provided. The apparatus provides a visual display of a calculated navigation route (22) with a visual indication (23) of the direction of desired travel along the navigation route. An off route map display portion (28) is provided which has the visual navigation route display (22) in one color and, in a second contrasting color, a visual display (24, 26) of actual vehicle travel. A separate additional feature is that an off route display (20) provides a visual display portion (29) of a plurality of operator selectable off route recovery options (1-6). Off route recovery means (12, 49-63) are provided such that the vehicle operator can implement the visually displayed recovery options. The result is a navigation system which visually provides vehicle navigation information to the vehicle operator in an improved minimal comprehension time format, and allows the vehicle operator to select for himself how to recover from an off route condition.
