METHOD FOR PAYING A FEE FOR ALLOWING A VEHICLE TO USE A ROAD NETWORK THAT IS SUBJECT TO TOLL CHARGES, AND TOLL SYSTEM FOR PERFORMING THE METHOD

摘要

The invention relates to a method and to a toll system for paying a fee for allowing a vehicle (1) to use a road network that is subject to toll charges. A random generator (2) generates a random character string (S) and transmits it to an electronic payment system (2) for handing the fee payment, and to a monitoring device (3) for an on-road check on a usage authorization of vehicles (1) using the road network. A user registers with the payment system (2) in order to acquire a usage authorization and in the process inputs a registration number (K) of the vehicle (1) intended for use. The payment system (2) uses a hash algorithm to generate a hash value (H) from the registration number (K) and the currently valid character string (S) and transmits said hash value to an electronic operator system (4) of a toll operator, which retains the transmitted hash value (H) for monitoring purposes. The monitoring device (3) uses video recordings and video evaluation of a passing vehicle (1) to record a registration number (K) of the vehicle (1) and likewise uses the hash algorithm to generate the hash value (H) from the recorded registration number (K) and the currently valid character string (S), and transmits said hash value to the operator system (4). The operator system (4) checks whether the hash value (H) transmitted by the monitoring device (3) matches a still-retained hash value (H) transmitted by the payment system (2). This enables time-dependent and distance-dependent levying of road usage fees in free-flowing traffic and monitoring of payment thereof, without having to permanently install specialized terminals in the vehicle (1) and while safeguarding the user's privacy.
