Abstract

Claims (38)

1. A road toll system comprising:

a vehicle-mounted unit for use in the road toll system, wherein the vehicle-mounted unit comprises a satellite navigation receiver implementing a position tracking function used by a routing system for determining routes taken by a vehicle based on position tracking information; and

a portable activation device that is not mounted on the vehicle, the portable activation device comprising:

a transmitter and receiver; and

a security module, wherein the security module is configured to implement user-personalization data to personalize the vehicle-mounted unit, wherein the user-personalization data is stored in the portable activation device separate from the vehicle-mounted unit, and wherein the security module applies a digital signature to route information received from the vehicle-mounted unit,

wherein the road toll system is adapted to establish a wireless communication channel between the security module and the vehicle-mounted unit via the transmitter and receiver;

wherein the portable activation device is adapted to transmit information concerning an owner of the portable activation device and the digitally signed route information to the vehicle-mounted unit via the wireless communication channel, and

wherein the vehicle-mounted unit is adapted to provide information to a billing system to enable identification of the owner of the portable activation device for billing a user of the system in dependence on the road prices incurred based on the routes taken.

2. The road toll system of claim 1 , wherein the portable activation device is a wireless device which is used to remotely unlock the vehicle.

3. The road toll system of claim 1 , wherein the portable activation device is a wireless device used to disable an immobilization unit of the vehicle.

4. The road toll system of claim 1 , wherein the vehicle-mounted unit comprises an element that can communicate wirelessly with a remote server to transmit route information which comprises information about routes taken and/or information about pricing relating to the routes taken, to the remote server.

5. The road toll system of claim 4 , wherein the vehicle-mounted unit is adapted to communicate with the portable activation device to send data for signature to the security module derived from the route information, and the security module is adapted to apply a digital signature to the data and return the signed data to the vehicle-mounted unit for communication by the vehicle-mounted unit to the remote server.

6. The road toll system of claim 5 , wherein the security module is further adapted to encrypt the data for signature.

7. The road toll system of claim 1 , wherein the portable activation device comprises one of:

a wireless smart card which is separate to a vehicle key;

part of a wireless vehicle key, wherein the same channel for immobilization is used as for transmitting information concerning the owner of the portable wireless activation device to the vehicle-mounted unit;

part of a wireless vehicle key, with a separate card reader provided for the reception by the vehicle-mounted unit of the information concerning the owner of the portable activation device to the channel for immobilization;

part of a key fob of the vehicle key; and

part of a smart card vehicle key, wherein the information concerning the owner of the portable activation device is transmitted to the vehicle-mounted unit by a wired link between the vehicle-mounted unit and smart card vehicle key when inserted in a key slot.

8. A method of implementing road tolling in a road tolling system comprising a vehicle-mounted unit, the vehicle-mounted unit comprising a satellite navigation receiver and a transmitter and receiver to wirelessly communicate with a portable activation device, the portable activation device comprising a transmitter and receiver and a security module, the method comprising:

operating the satellite navigation receiver to implement a position tracking function in the vehicle-mounted unit used by a routing system for determining route information including routes taken by a vehicle based on the position tracking information;

using the vehicle-mounted unit transmitter to establish a wireless communication channel to send data derived from the route information to the portable activation device that is not mounted on a vehicle for the portable activation device to apply a digital signature to the route information using a security module, wherein the security module is configured to implement user-personalization data to personalize the vehicle-mounted unit, wherein the user-personalization data is stored in the portable activation device separate from the vehicle-mounted unit;

using the vehicle-mounted unit to transmit information concerning an owner of the portable activation device and the digitally signed data from the portable activation device to a billing system to enable identification of the owner of the portable activation device for billing a user of the system in dependence on the road prices incurred based on the routes taken.

9. The method of claim 8 , further comprising using the portable activation device to remotely unlock the vehicle and/or to disable an immobilization unit of the vehicle.

10. The method of claim 8 , further comprising establishing a communication channel between the security module of the portable activation device and the vehicle-mounted unit and comprising the vehicle-mounted unit communicating wirelessly with a remote server to transmit said digitally signed route information which comprises information about routes taken and/or information about pricing relating to the routes taken, to the remote server.

11. The method of claim 10 , further comprising:

the vehicle-mounted unit communicating with the portable activation device to send data for signature to the security module derived from the route information;

the security module applying a digital signature to the data and returning the signed data to the vehicle-mounted unit; and

the vehicle-mounted unit communicating the digitally signal data to the remote server.

12. The method of claim 11 , wherein the security module encrypts the data for signature.

13. A vehicle-mounted unit comprising:

a satellite navigation receiver configured to implement a position tracking function;

a transmitter-receiver unit configured for short-range wireless communication established over a wireless communication channel with a security module external to the vehicle-mounted unit and not mounted on a vehicle;

wherein the security module is configured to implement user-personalization data to personalize the vehicle-mounted unit, wherein the user-personalization data is stored in a portable activation device separate from the vehicle-mounted unit; and

an on-board unit configured to send data, which is derived from route information based on the position tracking function to the security module via the transmitter-receiver unit to be digitally signed by the security module and, once digitally signed, to send the signed data to a remote server.

14. The vehicle-mounted unit of claim 13 , wherein the transmitter-receiver unit is an active near field communication system coupled to the on-board unit.

15. The vehicle-mounted unit of claim 14 , wherein the external security module is the portable activation device.

16. The vehicle-mounted unit of claim 15 , wherein the portable activation device comprises a passive near-field communication system.
