Sensor device for detecting moisture on a roadway having at least one structure-borne sound sensor

摘要

In a sensor device for detecting moisture on a roadway of a vehicle, particularly a motor vehicle, with at least one structure-borne sound sensor, with at least one circuit carrier, wherein the structure-borne sound sensor is connected in a signal-conducting manner to the circuit carrier, it is provided in a manner important for the invention that at least one structure-borne sound sensor is arranged in a housing, that the housing has at least one flat constructed housing area, that the structure-borne sound sensor is connected to the flat constructed housing area, so as to conduct structure-borne sound signals, and in that the housing is constructed as a resonant body, that the at least one circuit carrier is arranged in the housing, that the housing is provided for mounting in a wheel arch of a vehicle, that at least one connecting means for producing a connection between the housing and the wheel arch is assigned to the housing, and that the connecting means is constructed to be vibration damping, at least in certain sections.circuit carrier.
