First Claim
Patent Images
1. A method of determining an absolute position for a motor vehicle, comprising the steps of:
- receiving information related to an absolute position of a remote source;
determining if the remote source is in line of sight of the motor vehicle;
determining a distance between the remote source and the motor vehicle; and
calculating the absolute position for the motor vehicle using the absolute position of the remote source and the distance when the remote source is in line of sight of the motor vehicle.

Abstract
A method of determining an absolute position for a motor vehicle is disclosed. The method includes steps of receiving information related to the absolute positions of one or more remote sources. The method further includes steps of determining distances to the one or more remote sources. Methods for selecting a subset of remote sources from a set of all available remote sources to be used in determining an absolute position for the motor vehicle are also disclosed.

8. A method of determining an absolute position for a motor vehicle, comprising the steps of:
-
receiving information from a plurality of remote sources, the information including an absolute position for each remote source; selecting a set of remote sources that are in line of sight of the motor vehicle; determining a distance to each remote source in the set of remote sources; selecting a subset of remote sources from the set of remote sources that are spread approximately evenly around the motor vehicle; and calculating the absolute position of the motor vehicle using the absolute position of each remote source in the subset of remote sources and using the distance to each remote source in the subset of remote sources. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
