ROAD TOLL SYSTEM LINKING ON BOARD UNIT WITH VEHICLE
First Claim
1. A road toll system comprising a vehicle-mounted unit comprising:
- a satellite navigation system implementing a position tracking function;
transmitting means for transmitting information to a remote server; and
a unique identification device for attaching to the vehicle such that it is permanently fixed in a stationary position relative to the vehicle, and associated with the satellite navigation system, wherein the road toll system function is enabled only when the identification device is present,wherein 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.

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.

10. A road toll system comprising a vehicle-mounted unit and a remote server, comprising:
-
a satellite navigation system implementing a position tracking function; and transmitting means for transmitting position or route information to the remote server, wherein the system is adapted to receive an odometer value for the vehicle when the system is installed or at a reset time, and wherein the system is adapted to compute a distance travelled based on the transmitted position or route information, thereby to enable comparison of a new odometer value with an expected odometer value. - View Dependent Claims (11, 12, 13, 14, 15, 16)
