Description
Die Erfindung betrifft eine Sensoranordnung zur Erfassung einer Umgebung eines Fahrzeugs, umfassend eine Reinigungsvorrichtung mit zumindest einer Spritzdüse, deren Spritzbereich im Wesentlichen auf zumindest einen Sensor der Sensoranordnung gerichtet ist.The invention relates to a sensor arrangement for detecting an environment of a vehicle, comprising a cleaning device with at least one spray nozzle, whose spray area is directed substantially to at least one sensor of the sensor arrangement.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Sensoranordnung zur Erfassung einer Umgebung eines Fahrzeugs anzugeben.The invention has for its object to provide a comparison with the prior art improved sensor arrangement for detecting an environment of a vehicle.
Die Aufgabe wird erfindungsgemäß mit einer Sensoranordnung gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved with a sensor arrangement having the features specified in
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Sensoranordnung sind Gegenstand der Unteransprüche. Advantageous embodiments of the sensor arrangement according to the invention are the subject of the dependent claims.
Eine Sensoranordnung zur Umgebungserfassung eines Fahrzeugs umfasst eine Reinigungsvorrichtung mit zumindest einer Spritzdüse, deren Spritzbereich im Wesentlichen auf zumindest einen Sensor der Sensoranordnung gerichtet ist.A sensor arrangement for detecting the surroundings of a vehicle comprises a cleaning device with at least one spray nozzle, the spray area of which is directed substantially onto at least one sensor of the sensor arrangement.
Erfindungsgemäß ist die Spritzdüse mit einer Scheinwerferreinigungsanlage zur Versorgung der Spritzdüse mit einer Reinigungsflüssigkeit gekoppelt.According to the invention, the spray nozzle is coupled with a headlight cleaning system for supplying the spray nozzle with a cleaning liquid.
Aus der erfindungsgemäßen Ausführung der Sensoranordnung resultiert in besonders vorteilhafter Weise, dass eine Versorgung der Spritzdüse mit der Reinigungsflüssigkeit über eine Versorgungsleitung der Scheinwerferreinigungsanlage möglich ist. Somit ist lediglich ein geringer Aufwand zur Realisierung der Reinigung des Sensors erforderlich, da eine weitere Versorgungsleitung zur Versorgung der Spritzdüse eine geringe Länge aufweisen kann und einfach integrierbar ist. Auch ist die Reinigungsflüssigkeit zur Reinigung der Scheinwerfer gleichzeitig zur Reinigung des Sensors verwendbar, so dass kein zusätzlicher Vorratsbehälter zur Bevorratung der Reinigungsflüssigkeit erforderlich ist.From the embodiment of the sensor arrangement according to the invention results in a particularly advantageous manner that a supply of the spray nozzle with the cleaning liquid via a supply line of the headlight cleaning system is possible. Thus, only a small effort to realize the cleaning of the sensor is required because a further supply line for supplying the spray nozzle may have a small length and is easy to integrate. Also, the cleaning liquid for cleaning the headlights can be used at the same time for cleaning the sensor, so that no additional reservoir for storing the cleaning liquid is required.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.

Eine maximale Reichweite Rmax des Radarsensors ergibt sich dabei wie folgt: mit
- Pe
- = Empfangsleistung des Radarsensors.
- P e
- = Received power of the radar sensor.
Dabei sagt die maximale Reichweite bzw. Detektionsentfernung, welche einer Spezifikation des Radarsensors zu entnehmen ist und beispielsweise 200 m beträgt, nichts darüber aus, welche Art von Radarziel mit welchem Radarrückstreuquerschnitt (kurz: RCS oder σ) bei welchem Signal-Rausch-Verhältnis (kurz: S/N) detektiert werden kann. Die mögliche Reichweite des Radarsensors ist häufig durch Umgebungsbedingungen und weitere Komponenten der Sensoranordnung
Bei einer hohen Relativgeschwindigkeit zwischen dem Fahrzeug und einem Radarziel ist die reale Reichweite des Radarsensors in der Regel kleiner als die physikalisch maximal mögliche Reichweite, da das Radarziel in mehreren Messzyklen detektiert wird, bevor es auf einem Datenbus des Fahrzeugs
Weiterhin ist die Reichweite des Radarsensors durch die Signalverarbeitung begrenzt, wobei eine Empfängerdynamik des Radarsensors theoretisch für weiter entfernte Radarziele ausreichend ist.Furthermore, the range of the radar sensor is limited by the signal processing, wherein a receiver dynamics of the radar sensor is theoretically sufficient for more distant radar targets.
Die maximale Reichweite des Radarsensors bzw. die maximale Entfernung des Radarziels mit einem definierten Radarrückstreuquerschnitt σ für die Detektion mittels des Radarsensors ergibt sich aus der so genannten Radargleichung wie folgt: mit
- Ps
- = Sendeleistung, Leistung des ausgestrahlten Signals am Ort des Senders,
- Gs
- = Sende-Antennengewinn,
- Ge
- = Empfangs-Antennengewinn,
- λ
- = Wellenlänge der Radarstrahlung,
- Pe,min
- = Empfangsleistung.
- P s
- = Transmission power, power of the emitted signal at the location of the transmitter,
- G s
- = Transmitting antenna gain,
- G e
- = Reception antenna gain,
- λ
- = Wavelength of the radar radiation,
- P e, min
- = Reception power.
