  • Patent number: 9269197
    Abstract: A method for generating toll information for vehicle devices in a road-toll system with a toll center and geographically distributed radio beacons. The method includes providing a set of location data of toll-requiring geo-objects from the respective local environment of a beacon in this beacon, recording a sequence of position data of a vehicle device in this vehicle device, if the aforementioned vehicle device is in the transmitting/receiving range of a beacon: receiving the location-data set from this beacon in the vehicle device, comparing the position-data sequence with the received location-data set in the vehicle device in order to generate toll information therefrom, and if the above-mentioned vehicle device is in the transmitting/receiving range of a beacon: transmitting the toll information from the vehicle device via the beacon to the toll center. The invention further relates to a vehicle device, a beacon and a monitoring device for such a road-toll system.

  • Patent number: 8732000
    Abstract: Method for determining toll fees for vehicles in a road toll system including vehicle-onboard units and positionally distributed beacons capable of communicating with the onboard units via radio signals. The method includes: providing a toll fee level and a validity time frame; retrieving an identifier of the onboard unit, the toll fee level and the validity time frame from the onboard unit as a data record; resetting the toll fee level, if the validity time frame has expired; increasing the toll fee level and storing the updated data record in the onboard unit and the beacon; transmitting a request for deletion of stored data records for this identifier to other beacons; transmitting the data record from the beacon to the central station, if no deletion request for the data record arrives within the validity time frame; and deleting the data record in the beacon.
