Method and apparatus for improving a vehicle safety system using a transponder and GPS
First Claim
1. A method for operating a pre-crash sensing system for a first vehicle having a global positioning system (GPS), the method comprising:
- receiving an acquired GPS satellite identifier;
generating first vehicle location data with said GPS;
transmitting said first vehicle location data and said satellite identifier to a second vehicle across a wireless vehicle network;
receiving second vehicle location data from said second vehicle; and
generating a coordinating satellite identifier for said second vehicle to acquire for updating said second vehicle location data.

Abstract
The present invention provides a method for operating a pre-crash sensing system for a first vehicle having a global positioning system (GPS). The method includes receiving an acquired GPS satellite identifier and generating first vehicle location data with the GPS system. The first vehicle location is transmitted along with the satellite identifier to a second vehicle across a wireless vehicle network. Location information is also received for a detected second vehicle. In response, the first vehicle transmits a request for updated second vehicle location information using a coordinating satellite identifier. The coordinating satellite identifier is then used by the second vehicle to update the second vehicle location data. In this way, both communicating vehicles are generating and sharing location information from a commonly acquired GPS source.
