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, wherein the vehicle-mounted unit and a unique identification device are installed within the same vehicle, the remote server comprising a satellite navigation system implementing a position tracking function, the remote server receiving position or route information of the vehicle from the vehicle-mounted unit,wherein the remote server is adapted to receive an odometer value for the vehicle when the system is installed or reset, andwherein the remote server is adapted to compute a distance travelled 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,wherein the vehicle-mounted unit will not function if the unique identification device is not present and a mismatch between the expected odometer value and the new odometer value of the vehicle will accrue.

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.

12. A method of operating in a road toll system comprising:
-
at a server remote from a vehicle-mounted unit, wherein the vehicle-mounted unit is installed within the same vehicle as a unique identification device; implementing a position tracking function using a satellite navigation system; receiving position or route information from the vehicle-mounted unit; receiving an odometer value for the vehicle when the system is installed or reset; computing a distance travelled based on the receiver position or route information; and
comparing 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;wherein the vehicle-mounted unit will not function if the unique identification device is not present and a mismatch between the expected odometer value and the new odometer value of the vehicle will accrue. - View Dependent Claims (13, 14, 15, 16, 17, 18)
