METHOD AND DEVICE FOR DETECTING A TRAFFIC LAW VIOLATION DUE TO THE ALLOWABLE DISTANCE BETWEEN A FOLLOWING VEHICLE AND A GUIDE VEHICLE BEING UNDERSHOT

摘要

The invention relates to a method (200) for detecting a traffic law violation due to the allowable distance (Dmin) between a following vehicle (110) and a guide vehicle (115) being undershot, said following vehicle traveling behind the guide vehicle (115). The method (200) has a step (220) of identifying at least the respective speed (v1, v2) of the following vehicle (110) and the guide vehicle (115) in a detection region (125) in the surroundings of a sensor (130) which supplies speed measurement values, wherein measurement values for identifying the speed (v1, v2) of the following vehicle (110) and the guide vehicle (115) are detected simultaneously in the detection region (125) in particular. The method (200) additionally has a step (230) of detecting and/or ascertaining a reference distance (140) between the following vehicle (110) and the guide vehicle (115) at a reference measurement point (145). The method (200) also has a step (240) of determining at least one following distance (160) between the following vehicle (110) and the guide vehicle (115) in the detection region (125) using the identified speeds (v1, v2) of the following vehicle (110) and the guide vehicle (115) and/or the detected reference distance (140). The method (200) finally has a step (250) of detecting a traffic law violation if the following distance (160) in the detection region (125) continuously falls short of a distance threshold (Dmin).
