Abstract
A method of tolling vehicles in an open-road toll system with vehicle-based on-board units and roadside radio beacons. The method includes transmitting transaction information and a factor from the on-board unit; updating the factor as a function of the transmitted transaction information and calculating a debit amount as a function of the updated factor; transmitting a debit request with the calculated debit amount and the updated factor to the on-board unit; and debiting the received debit amount to a toll credit account in the on-board unit and writing a new transaction information concerning this new debit transaction and the received updated factor into the on-board unit.
Claims16
A method of tolling vehicles in an open-road toll system with vehicle-based on-board units that are able to communicate with roadside radio beacons via short-range radio interfaces, the on-board units comprising a first memory for an electronic toll credit account, a second memory for a transaction information concerning a last debit to the toll credit account, and a third memory for a variable factor, and the radio beacons sending requests for debiting a debit amount to the toll credit account to passing on-board units, the method comprising the following steps that are carried out as an on-board unit passes a toll beacon:
- retrieving the transaction information from the second memory and the factor from the third memory of the on-board unit via the radio interface into the toll beacon;
- updating the factor as a function of the retrieved transaction information and calculating a debit amount as a function of the updated factor in the toll beacon;
- transmitting a debit request with the calculated debit amount and the updated factor from the toll beacon via the radio interface to the on-board unit;
- and
- debiting the transmitted debit amount to the toll credit account in the first memory as a new debit transaction, storing a new transaction information concerning said new debit transaction in the second memory, and storing the received updated factor in the third memory of the on-board unit.
