Control Method for a Road Toll System
First Claim
1. A control method for a road toll system which is based on on-board units carried by vehicles, using at least one recording vehicle and at least one control vehicle, which can wirelessly communicate with a central violation server, the method comprising:
- in the recording 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 violation data record, containing a determined location of the violation and a read license plate number of the vehicle, to a violation server;
in the violation server;
registering control vehicles, including positions or the surroundings thereof,receiving violation data records from recording vehicles and, if the locations of the violations thereof are within the surroundings of a position,providing the violation data records to a control vehicle that is registered with this position or these surroundings;
in the control vehicle;
registering the position or surroundings thereof in the violation server,reading the license plate number of a passing vehicle,determining a violation data record provided by the violation server for a read license plate number and, if such a record exists,issuing an alert message;
wherein, during the transmission of a violation data record from the recording vehicle to the violation server and/or from the violation server to the control vehicle, the violation data record is divided into two parts, of which the first part contains at least the location of the violation and the license plate number read result, and the second part contains additional violation data, and the first part is transmitted via a connection-oriented and the second part is transmitted via a connectionless packet-switched transport protocol.

Abstract
Control devices and methods for a road toll system that is based on vehicle-based on-board units, using recording vehicles, control vehicles and a violation server, wherein the recording vehicle reads out a toll parameter from the on-board unit of a passing vehicle via a DSRC radio interface, compares it to a shape parameter of the vehicle detected by a sensor, and based thereon, in case of inconsistency, generates a violation data record and transmits it to the violation server, wherein the control vehicle registers the position or surroundings thereof in the violation server, and the violation server makes available to a control vehicle such violation data records, the locations of the violations of which are within the surroundings of a position of the control vehicle, wherein the control vehicle issues an alert message when it detects a violating vehicle in the surroundings, and wherein, during the transmission of a violation data record from the recording vehicle to the violation server and/or from the violation server to the control vehicle, the violation data record is divided into a TCP part and a UDP part.
