Abstract: A method for detecting a traffic law violation due to the allowable distance between a following vehicle and a guide vehicle being undershot, the following vehicle traveling behind the guide vehicle. At least the respective speed of the following vehicle is identified and the guide vehicle in a detection region in the surroundings of a sensor which supplies speed measurement values. A reference distance is detected and/or ascertained between the following vehicle and the guide vehicle at a reference measurement point. At least one following distance is determined between the following vehicle and the guide vehicle in the detection region using the identified speeds of the following vehicle and the guide vehicle and/or the detected reference distance. A traffic law violation is detected if the following distance in the detection region continuously falls short of a distance threshold.

Abstract: A method for monitoring and/or detecting a sensor system of a vehicle comprises a step of identifying a parameter value using a response signal, and a step of determining a monitoring signal that can be allocated to the sensor system, said determination being carried out using the parameter value and a predetermined reaction value.

Abstract: The invention relates to a housing (102) for a mobile traffic monitoring device (104), wherein the housing (102) can be coupled to a carrier vehicle (200) via a fastening interface (108), and wherein the housing (102) is designed as a luggage transport rack.
