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.
