Method for automatic billing in a fee or toll charging system

摘要

The method involves transmitting an acoustic or optical signal (13,14) or a message (15) by the vehicle-based device during approach or passing a toll system boundary (10) of the toll system (12) or with disconnection or detachment of the vehicle-based device from the power supply. The message is transmitted to a central system of the toll charging or a toll system. An independent claim is included for a vehicle-based device with software for producing signals.
