Erfindungsgemäß sind die zumindest zwei Heizdrähte (3.1) einer Sende- und Empfangseinheit des Sensors (2) orthogonal zueinander angeordnet.The invention relates to a protective cover (1) for a sensor (2) for detecting the surroundings of a vehicle, comprising a heating element (3) with at least two heating wires (3.1). According to the invention, the at least two heating wires (3.1) of a transmitting and receiving unit of the sensor (2) are arranged orthogonal to one another.
Description
Die Erfindung betrifft eine Schutzabdeckung für einen Sensor zur Umgebungserfassung eines Fahrzeuges, umfassend ein Heizelement mit zumindest zwei Heizdrähten.The invention relates to a protective cover for a sensor for detecting the surroundings of a vehicle, comprising a heating element with at least two heating wires.

Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Schutzabdeckung für einen Sensor zur Umgebungserfassung eines Fahrzeuges anzugeben.The invention has for its object to provide a comparison with the prior art improved protective cover for a sensor for detecting the environment of a vehicle.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Schutzabdeckung für einen Sensor zur Umgebungserfassung eines Fahrzeuges umfasst ein Heizelement mit zumindest zwei Heizdrähten, wobei erfindungsgemäß vorgesehen ist, dass die zumindest zwei Heizdrähte einer Sende- und Empfangseinheit des Sensors orthogonal zueinander angeordnet sind.A protective cover for a sensor for detecting the surroundings of a vehicle comprises a heating element with at least two heating wires, wherein it is provided according to the invention that the at least two heating wires of a transmitting and receiving unit of the sensor are arranged orthogonal to one another.
Dabei ist das Heizelement dazu vorgesehen, einen Erfassungsbereich des Sensors zumindest von Schnee und Eis zu befreien und/oder freizuhalten.In this case, the heating element is provided to free a detection range of the sensor at least from snow and ice and / or free.
Mittels einer derartigen Anordnung der Heizdrähte ist eine Deformation der Schutzabdeckung des Sensors im Bereich der Heizdrähte, wobei der Sensor beispielsweise im Bereich eines Kühlergrills des Fahrzeuges angeordnet ist und die Schutzabdeckung durch einen Parkrempler deformiert wurde, auf vergleichsweise zuverlässige Weise erfassbar.By means of such an arrangement of the heating wires, a deformation of the protective cover of the sensor in the region of the heating wires, wherein the sensor is arranged, for example, in the region of a radiator grille of the vehicle and the protective cover has been deformed by a parking bump, can be detected in a comparatively reliable manner.
Insbesondere kann mittels einer solchen Anordnung der Heizdrähte eine gleichmäßige Verformung der Schutzabdeckung, welche als Sende- und Empfangsschutzhülle für den Sensor dient, erkannt werden.In particular, by means of such an arrangement of the heating wires a uniform deformation of the protective cover, which serves as a transmitting and receiving protective cover for the sensor, can be detected.
Üblicherweise kann eine solche gleichmäßige Deformation der Schutzabdeckung unerkannt bleiben, wenn ein Sendepfad eines mittels des Sensors gesendeten Signals und ein Empfangspfad eines reflektierten und empfangenen Signals unerkannt bleiben, sofern sowohl ein Sendepfad als auch ein Empfangspfad des Sensors gleich abgelenkt werden.Usually, such a uniform deformation of the protective cover can go undetected if a transmission path of a signal transmitted by the sensor and a reception path of a reflected and received signal go undetected, provided that both a transmission path and a reception path of the sensor are deflected the same.
