Description
Die Erfindung betrifft ein Kraftfahrzeug-Radarsystem mit einem Radarsensor, der mehrstrahlig mit wenigstens zwei horizontal nebeneinander liegenden Sende- oder Empfangskeulen ausgebildet ist, wobei der Radarsensor mittels eines Halterahmens mit einem Kraftfahrzeug verbindbar ist, und wobei die Sende- und Empfangskeulen des Radarsensors horizontal, vertikal und um eine Kraftfahrzeuglängsachse verschwenkbar angeordnet sind.The The invention relates to a motor vehicle radar system with a radar sensor, the multi-beam with at least two horizontally adjacent Transmitting or receiving lobes is formed, wherein the radar sensor can be connected to a motor vehicle by means of a holding frame, and wherein the transmit and receive lobes of the radar sensor are horizontal, arranged vertically and pivotable about a motor vehicle longitudinal axis are.
Derartige Radarsystem werden eingesetzt, um ein Abbild des Bereichs vor einem Kraftfahrzeug mittels mehrerer horizontal nebeneinander angeordneter Radarkeulen beispielsweise zum Zwecke eines ACC Adaptive Cruise Control Stop and Go Systems zu generieren. Da die horizontal nebeneinander angeordneten Radarkeulen in ihren jeweiligen seitlichen Endbereichen jeweils einen in etwa gleichen Abstand zum Boden aufweisen müssen, um eine zuverlässige Messung zu gewährleisten, wird eine entsprechende Justiermöglichkeit benötigt.such Radar system are used to image the area in front of you Motor vehicle by means of several horizontally arranged side by side Radar lobes, for example, for the purpose of an ACC Adaptive Cruise Control Stop and Go Systems. Since the horizontally next to each other arranged radar lobes in their respective lateral end portions must each have an approximately equal distance from the ground to a reliable one To ensure measurement becomes a corresponding adjustment option needed.

Nachteilig an einer derartigen Justage der Antennenlinse ist der große konstruktive Aufwand, der betrieben werden muss, um die Antennenlinse gegenüber dem Radarsensor einerseits verstellbar zu gestalten und andererseits eine langlebige und Erschütterungen standhaltende Befestigung zu gewährleisten.adversely on such an adjustment of the antenna lens is the great constructive Effort that must be operated to the antenna lens over the Radar sensor on the one hand to make adjustable and on the other hand a long lasting and shaking to ensure stable attachment.
Der Erfindung liegt die Aufgabe zugrunde, einen Radarsensor der eingangs genannten Art derart weiterzubilden, dass eine Justierbarkeit insbesondere in Form einer Verschwenkbarkeit um die Fahrzeuglängsachse ermöglichst ist, und gleichzeitig den konstruktiven Aufwand möglichst gering zu halten.Of the Invention is based on the object, a radar sensor of the above so-called type such that an adjustability in particular in the form of a pivoting about the vehicle longitudinal axis ermöglichst is, and at the same time the design effort as possible to keep low.
Um diese Aufgabe zu lösen ist vorgesehen, dass zwischen dem Radarsensor und dem Halterahmen ein Zwischenrahmen angeordnet ist, mit dem der Radarsensor fest verbunden ist, wobei der Zwischenrahmen gegenüber dem Halterahmen derart einstellbar gelagert ist, dass die Sende- und Empfangskeulen horizontal, vertikal und um eine Kraftfahrzeuglängsachse verschwenkbar sind. Durch den Halterahmen wird der Radarsensor als feste Einheit gestaltet, indem der Radarsensor und die Antennenlinse fest miteinander verbunden sind. Zur Verschwenkung des Radarsensors um die Kraftfahrzeuglängsachse wird der gesamte Radarsensor inklusive der Antennenlinse mittels des Zwischenrahmens gegenüber dem Halterahmen verschwenkt. Der dafür erforderliche Aufwand zur Verschwenkung des Zwischenrahmens gegenüber dem Halterahmen ist vergleichsweise gering und wenig störungsanfällig, so dass der konstruktive Aufwand für die vorliegende Lösung relativ gering ist.Around to solve this task is provided that between the radar sensor and the support frame an intermediate frame is arranged, with which the radar sensor fixed is connected, wherein the intermediate frame relative to the support frame adjustable is stored, that the send and receive lobes horizontal, vertical and a motor vehicle longitudinal axis are pivotable. Through the holding frame of the radar sensor as solid unit designed by the radar sensor and the antenna lens are firmly connected. For pivoting the radar sensor around the motor vehicle longitudinal axis is the entire radar sensor including the antenna lens by means of of the intermediate frame opposite pivoted the holding frame. The required effort for Pivoting the intermediate frame relative to the support frame is relatively low and less prone to failure, so that the constructive effort for the present solution is relatively low.
Weitere konstruktive Ausgestaltungen ergeben sich aus den Unteransprüchen. Dabei ist vorgesehen, dass die Verschwenkbarkeit um die Fahrzeuglängsachse mittels einer Dreipunktlagerung mit ersten, zweiten und dritten Lagerpunkten erfolgt. Zudem kann der erste Lagerpunkt als Drehpunkt des Zwischenrahmens gegenüber dem Halterahmen ausgebildet sein, wobei der Zwischenrahmen im Bereich der zweiten und dritten Lagerpunkte jeweils Länglöcher aufweist und die Längsachsen der Langlöcher jeweils um etwa 45° gegenüber der Senkrechten geneigt sind. Weiterhin kann vorgesehen sein, dass wenigstens im Bereich des dritten Lagerpunktes ein Zahnradgetriebe zur Justierbarkeit des Zwischenrahmens gegenüber dem Halterahmen angeordnet ist, wobei der Zwischenrahmen im Bereich des dritten Lagerpunktes einen zahnstangenartigen Bereich aufweist und am Halterahmen im Bereich des dritten Lagerpunktes ein Haltebolzen anbringbar ist, der einem kreisrunden Zahnradbereich aufweist, der mit dem zahnstangenartigen Bereich korrespondierend ausgeführt. Damit ist es ermöglicht, durch Drehung des Haltebolzens eine Relativbewegung zwischen dem kreisrunden Zahnbereich des Haltebolzens und dem zahnstangenartigen Bereich des Zwischenrahmens eine Relativbewegung zu erzeugen, die eine Verschwenkung des Zwischenrahmens gegenüber dem Halterahmen um die Schwenkachse des ersten Lagerpunktes bewirkt.Further constructive embodiments emerge from the dependent claims. there is provided that the pivoting about the vehicle longitudinal axis by means of a three-point bearing with first, second and third Storage points takes place. In addition, the first bearing point as a fulcrum of the intermediate frame opposite be formed of the holding frame, wherein the intermediate frame in the area the second and third bearing points each have longitudinal holes and the longitudinal axes the long holes each at about 45 ° from the Vertical are inclined. Furthermore, it can be provided that at least in the area of the third bearing point a gear transmission for adjustability of the intermediate frame opposite the holding frame is arranged, wherein the intermediate frame in the region of third bearing point has a rack-like area and on the holding frame in the region of the third bearing point a retaining bolt attachable, which has a circular gear portion, the executed corresponding to the rack-like region. In order to is it possible by rotation of the retaining pin a relative movement between the circular Tooth area of the retaining bolt and the rack-like area the intermediate frame to produce a relative movement, the pivoting of the intermediate frame opposite causes the holding frame about the pivot axis of the first bearing point.
