VEHICLE TRACKING SYSTEMS AND METHODS

摘要

Vehicle tracking systems and methods are provided. A Global Positioning System (GPS) receiver is operative to generate first, GPS, data identifying the vehicle's current position from GPS signals. An On Board Diagnostics (OBD) Hardware Interface is operative to generate second, OBD, data identifying the vehicle's current position by using dead reckoning techniques. Arbitration means are provided to arbitrate between the first and second data by performing integrity checks thereon to generate data giving an improved identification of the vehicle's current position.
