Patent ID: 8521412

Claim:
A method of determining an absolute position for a motor vehicle including an electronic control unit, the electronic control unit being configured to perform the method comprising the steps of: receiving signals via a communication system, the signals containing information from a plurality of remote sources within a communication range of the communication system, the information including an absolute position for each remote source; selecting a set of remote sources of the plurality of remote sources that are in line of sight of the motor vehicle; excluding any remote sources of the plurality of remote sources that are not 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.
