The invention relates to a method for addressing at least one bus subscriber, in particular a control device or sensor, which is connected to a bus system for the purpose of exchanging data, and which is supplied with DC voltage in order to supply the bus subscriber with supply voltage rectified as defined via a DC voltage input of said bus subscriber. It is proved according to the invention that the respective bus subscriber detects the polarity of the DC voltage at its DC voltage input, selects a predefined address depending on the detected polarity, and assigns the selected address to itself for the purpose of exchanging the data. The invention further relates to the bus subscriber and a system consisting of a bus system and exactly two bus subscribers of such kind. The invention also relates to a motor vehicle.

Method for addressing at least one bus subscriber and bus subscriber as well as system and motor vehicle equipped therewith

In a method for capturing a condition of a surface of a road on which a vehicle is travelling, wherein at least one signal produced as a result of moisture thrown up from the road is captured by means of at least one sensor apparatus arranged on the vehicle, wherein the sensor apparatus includes at least one sensor device, and wherein the captured signal is evaluated by means of at least one evaluation device attached to the vehicle, it is provided as essential to the invention that at least one physical parameter of the thrown up moisture is captured by at least one sensor device, and that a conclusion is reached regarding the salt content of the moisture which reaches the sensor apparatus on the basis of at least one captured physical parameter, and a conclusion is reached regarding the condition of the road based on the salt content. The invention relates further to a sensor apparatus for a vehicle for capturing a condition of a surface of a road on which a vehicle is travelling having at least one sensor apparatus for detecting moisture thrown up by the vehicle tyres.

A device for detecting a structure-borne sound signal, in particular for detecting a structure-borne sound signal caused by an event of damage on a component to be monitored, having at least one structure-borne sound sensor, at least one signal-conducting connection of the structure-borne sound sensor to an evaluation device, and a protective body. The structure-borne sound sensor has a structure-borne sound-conducting connection to the protective body and the protective body has a structure-borne sound-conducting connection to the component to be monitored.
