Abstract
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.
Claims23
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.
A control method for a road toll system that is based on on-board units carried by vehicles, using 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, the method comprising:
- in the marking vehicle:
- detecting a traffic or toll violation of an on-board unit, or of a vehicle carrying the same, and, if a violation exists, transmitting a marker to the on-board unit via the DSRC radio interface;
- in the on-board unit:
- periodically determining, upon receipt of a marker, the position of the on-board unit and broadcasting position messages containing the respective current position thereof;
- in the control unit:
- detecting the vehicle based on at least one of the position messages that are broadcast by the on-board unit.
