Vehicle Position Determining System and Method
First Claim
1. A vehicle positioning system for enabling a vehicle to determine its position while traveling on a road, comprising:
- determining means arranged on the vehicle for determining an identity of at least one marker as the vehicle passes said at least one marker; and
positioning means on the vehicle coupled to said determining means and providing positions of markers and their identifications, such that once the identity of said at least one marker is determined, the position of said at least one marker is provided and the position of the vehicle is derived from the position of the at least one marker.

Abstract
Vehicle positioning system and method for enabling a vehicle to determine its position while traveling on a road in which an identity of at least one marker is determined as the vehicle passes each marker. The position of each marker is determined from its identification, e.g., with reference to a database, and thus the position of the vehicle, can be determined. Various markers may be used, including fixed markers arranged proximate the road. If three such fixed markers are provided, the position of the vehicle can be determined using triangulation. The fixed markers may be visual markers, passive transponder-type markers, active transponder-type markers and/or reflectors.

12. A method for enabling a vehicle to determine its position while traveling on a road, comprising:
-
determining an identity of at least one marker as the vehicle passes the at least one marker; and
determining the position of the at least one marker and thus the position of the vehicle based on the identity of the at least one marker. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for enabling a vehicle to determine its position while traveling on roads, comprising:
-
fixing a plurality of groups of markers in fixed positions alongside, on or in the road;
forming a database containing the identity of the markers and their position; and
providing the database to a processor on the vehicle such that when the vehicle passes a group of markers, it interacts with the markers, determines an identity of each marker and then by accessing the database, determines the position of the markers and thus the position of the vehicle. - View Dependent Claims (19, 20)
