Control devices and methods for a road toll system that is based on on-board units carried by vehicles, comprising: in a marking vehicle detecting a traffic or toll violation of an on-board unit, and, if a violation exists, transmitting a marker to the on-board unit via a DSRC radio interface; in an on-board unit periodically determining, upon receipt of a marker, the position of the unit and broadcasting a position message containing the respective current position; and in the control unit: detecting the vehicle based on at least one of the position messages that are broadcast by the on-board unit.

主权项

1. A control device for a road toll system based on on-board units carried by vehicles, comprising:
at least one marking vehicle, at least one on-board unit, and at least one control unit, each comprising a dedicated short range communication (DSRC) transceiver for establishing a DSRC radio interface, wherein the marking vehicle is configured to detect a traffic or toll violation of an on-board unit, or of a vehicle carrying the same, and, if a violation exists, to transmit a marker to the on-board unit via the DSRC radio interface, wherein the on-board unit is configured to determine the position thereof and, upon receipt of a marker, to periodically broadcast position messages containing the respective current position thereof, and wherein the control unit is configured to detect the vehicle based on at least one of the position messages broadcast by the on-board unit.
