ROAD TOLL SYSTEM LINKING ON BOARD UNIT WITH VEHICLE
First Claim
1. A road toll system comprising:
- a remote server in communication with a vehicle-mounted unit, the remote server comprising a satellite navigation system implementing a position tracking function, the remote server receiving position or route information from the vehicle-mounted unit, wherein the remote server is adapted to receive an odometer value for the vehicle when the system is installed, at a reset time, or at a verification time, and wherein the remote server is adapted to compute a distance traveled based on the received position or route information and compare a new odometer value for the vehicle received from the vehicle-mounted unit with an expected odometer value for the vehicle based on the computed distance traveled.

Abstract
A road toll system comprises a vehicle-mounted unit comprising a satellite navigation system implementing a position tracking function; transmitting means for transmitting position or route information to a remote server; and a unique identification device for attaching to the vehicle, and associated with the satellite navigation receiver. The road toll system function is enabled only when the identification device is present. The identification device comprises an electronic device which is adapted to alter by detachment or attempted detachment such as to prevent the road toll system function being enabled. This system increases the security of this type of system and makes fraudulent use of the system increasingly difficult.
