Aus
der deutschen Offenlegungsschrift
Aufgabe der Erfindung ist es deshalb, ein Verfahren und eine zur Durchführung des Verfahrens geeignete Vorrichtung zu finden, mittels welcher ungefährliche, sich auf oder in der Fahrbahnoberfläche befindliche Objekte mit geringer Höhenausdehnung als solche erkannt werden, so dass störende Warnungen und unnötige Eingriffe in die Fahrzeugdynamik vermieden werden können.task The invention is therefore a method and a for carrying out the To find a suitable device by means of which harmless, on or in the road surface located objects with low height expansion be recognized as such, so that annoying warnings and unnecessary interventions can be avoided in the vehicle dynamics.
Die Aufgabe wird durch ein Verfahren und eine zur Durchführung des Verfahrens geeignete Vorrichtung mit den Merkmalen der Patentansprüche 1 und 5 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung werden durch die Unteransprüche beschrieben.The Task is performed by a procedure and to carry out the Method suitable device with the features of claims 1 and 5 solved. Advantageous embodiments and further developments of the invention will be by the subclaims described.
Zur Detektion und Identifikation von Objekten mit geringer Höhenausdehnung auf einer in Fahrtrichtung vor einem Fahrzeug befindlichen Fahrbahn, wird mittels von einem Sender ausgesandter elektromagnetischer Strahlung in Fahrtrichtung vor dem Fahrzeug ein Bereich der sich dort befindlichen Fahrbahn ausgeleuchtet. Aus diesem Fahrbahnbereich werden sodann mittels eines Empfängers Teile der Von diesem Bereich reflektierten elektromagnetischen Strahlung empfangen und einer Auswertung hinsichtlich dort detektierbarer Objekte unterzogen. Hierbei wird bei der Detektion eines Objekts, dessen Entfernung zum Fahrzeug bestimmt und darauf basierend ein Gefährdungspotential bezüglich des Fahrbetriebs abgeleitet, um dementsprechend auf ein Fahrerassistenzsystem einzuwirken.to Detection and identification of objects with low height expansion on a lane in front of a vehicle in the direction of travel, is emitted by means of a transmitter emitted electromagnetic radiation in the direction of travel in front of the vehicle an area of the located there Road lit up. From this roadway area are then by means of a receiver Parts of the electromagnetic radiation reflected from this area received and an evaluation regarding there detectable objects subjected. This is in the detection of an object whose Distance to the vehicle determined and based on a potential hazard in terms of derived from the driving operation, to a driver assistance system accordingly act.
In erfinderischer Weise wird hierbei die Fahrbahn in einem Bereich bis zu einer Entfernung rges ausgeleuchtet. Die empfangenen, reflektierten Signale werden sodann in einer Signalverarbeitungseinheit daraufhin untersucht, ob ein Objekt erst in einer Entfernung rObjekt mit rObjekt < rBoden detektiert wird. Das Verfahren geht dabei von der Radargleichung aus, welche den Zusammenhang zwischen der von einem Radarsystem ausgesandten Strahlung, den Streueigenschaften eines Objektes und den empfangenen Signalen beschreibt mit der Empfangsleistung PE, der Sendeleistung PS, dem Antennengewinn G, dem Abstand zu dem Objekt R, Rückstreuquerschnitt σ des Objekts und der Wellenlänge λ der ausgestrahlten Welle. Aus der Gleichung (1) wird ersichtlich, dass Objekte mit einem geringen Rückstreuquerschnitt, also insbesondere Objekte mit geringer Höhenausdehnung, erst in naher Entfernung rObjekt von dem Radarsystem detektiert werden können, obwohl sie sich bereits schon länger in dem Erfassungsbereich mit maximal erfassbarer Entfernung rges des Radarsystems befinden. Erfolgt also eine Detektion eines Objektes erst in einer Entfernung rObjekt < rBoden, welche näher am Fahrzeug liegt als eine Schwellentfernung rBoden für relevante Bodenziele (mit rBoden < rges) wird davon ausgegangen, dass es sich bei dem detektierten Objekt um ein Objekt mit geringer Höhenausdehnung (Bodenziel) handelt, welchem alsdann kein beachtliches Gefährdungspotential beizumessen ist, so dass kein Einwirken auf ein Fahrerassistenzsystem erfolgt.In an inventive manner, in this case the roadway is illuminated in a range up to a distance r ges . The received, reflected signals are then examined in a signal processing unit to determine whether an object is detected only at a distance r object with r object <r bottom . The procedure is based on the radar equation which describes the relationship between the radiation emitted by a radar system, the scattering properties of an object and the received signals with the received power P E , the transmission power P S , the antenna gain G, the distance to the object R, backscatter cross section σ of the object and Wavelength λ of the radiated wave. From the equation (1) it can be seen that objects with a small Rückstreuquerschnitt, ie in particular objects with low height extension, only at close range r object can be detected by the radar system, although they are already longer in the detection range with maximum detectable distance r ges of the radar system. Thus, if a detection of an object takes place only at a distance r object <r ground which is closer to the vehicle than a threshold distance r ground for relevant ground targets (with r ground <r ges ), it is assumed that the detected object is a Object with low height extent (ground target) is, which then no significant hazard potential is attributed, so that no effect on a driver assistance system.
Bei derartigen nichtbeachtlichen Objekten mit geringer Höhenausdehnung, so genannte Bodenziele, handelt es sich typischerweise um bodennahe Ziele wie Schachtdeckel oder Dehnungsfugen (Plattensprüngen) oder aber auch um auf der Fahrbahn befindlichen Unrat. Sehr wohl kann es sich dabei aber auch um von Schachtdeckeln aufsteigenden Wasserdampf handeln, der auch in seiner Höhenausdehnung deutlich wahrnehmbar ist, selbstverständlich für den Fahrbetrieb des Fahrzeuges keine Gefahr birgt. Eine derartige Dampfsäule weist trotz ihrer signifikanten Höhenausdehnung jedoch nur einen geringen Rückstreuquerschnitt auf, so dass diese in vorteilhafter Weise ebenfalls wie ein Objekt mit geringer Höhenausdehnung behandelt wird.at such nonobservant objects with small height extension, so-called ground targets, are typically near the ground Targets such as manhole covers or expansion joints (plate jumps) or but also on the roadway debris. Very well but it is also rising from manhole covers water vapor act, which also in its height extent clearly perceptible, of course, for the driving of the vehicle no danger. Such a vapor column, despite its significant height extension but only a small Rückstreuquerschnitt on, so this in an advantageous way also like an object with low height expansion is treated.
Um insbesondere die Funktions- und Erkennungssicherheit zu verbessern, kann das erfindungsgemäße Verfahren in vorteilhafter Weise dadurch erweitert werden, dass die reflektierte elektromagnetische Strahlung zusätzlich aus wenigstens zwei in Bezug auf die Fahrbahnoberfläche unterschiedlich geneigten Winkeln oder Winkelbereichen ausgewertet wird. Ausgehend von dieser Auswertung wird dann ein Objekt als Objekt mit geringer Höhenausdehnung identifiziert, wenn es in der reflektierten Strahlung aus einem zur Fahrbahnoberfläche steileren Winkel bzw. Winkelbereich detektiert wird, während es gleichzeitig in der reflektierten Strahlung aus einem bezüglich der Fahrbahnoberfläche flacheren Winkel bzw. Winkelbereich nicht detektiert wurde. Wird einem Objekt derart eine geringe Höhenausdehnung zugeschrieben, so wird ihm kein beachtliches Gefährdungspotential beigemessen, so dass kein Einwirken auf ein Fahrerassistenzsystem erfolgt.Around in particular to improve the functional and recognition reliability, can the inventive method be extended advantageously by the fact that the reflected electromagnetic radiation in addition of at least two different with respect to the road surface inclined angles or angular ranges is evaluated. outgoing From this evaluation then an object as an object with low height extension identified when it is in the reflected radiation from a to the road surface steeper angle or angular range is detected while it simultaneously in the reflected radiation from a relative to the road surface flatter angle or angular range was not detected. Becomes attributed to such an object a small height extent, so he is not given a considerable hazard potential, so that no effect on a driver assistance system.
In besonders vorteilhafter Weise macht sich die Erfindung die Tatsache zu Nutze, dass bei den für den Fahrbetrieb unbeachtlichen Objekten mit geringer Höhenausdehnung (beispielsweise Getränkebecher oder -dosen oder Papiertüten) eine genaue Kenntnis über deren Abmessung nicht von Interesse ist. So wird gewinnbringend eine Identifikation möglich welche auf aufwendige Signalverarbeitung oder hochauflösende Radarsensorik verzichten kann.In Particularly advantageously, the invention makes the fact to take advantage of that for the the driving operation irrelevant objects with low height expansion (for example, beverage cups or cans or paper bags) an exact knowledge about whose dimension is not of interest. It will be profitable an identification possible which on elaborate signal processing or high-resolution radar sensor can do without.
Während sich die Erfindung selbstverständlich auch mittels der gezielten Auswertung unterschiedlich ausgerichteter Empfangszweige eines hochauflösenden Radarsystems realisieren lässt, eignet sie sich vor allem für die gemeinsame Verwendung mit einer Mehrzahl von Radargeräten mit relativ breitem Empfangsbereich, welche in Bezug auf die Fahrbahnoberfläche unter einem anderen Winkel am Fahrzeug ausgerichtet sind.While the invention of course also by means of the targeted evaluation differently oriented Reception branches of a high-resolution Radar system, It is especially suitable for sharing with a plurality of radars with relatively wide reception area, which in relation to the road surface below aligned at a different angle on the vehicle.
Dabei kann es sich bei den mehreren Radarsystemen beispielsweise um mehrere Millimeterwellenradare oder mehrere Laserradare (Lidar) handeln oder aber auch aus einer Mischung aus beiden Arten von Systemen. Dabei ist eine Kombination unterschiedlicher Radarsysteme völlig unproblematisch, da erfindungsgemäß nicht sensor-spezifische Eigenschaften der Reflektionssignale ausgewertet werden, sondern im Wesentlichen nur ein Test auf das Vorhandensein von Reflektionssignalen als solcher stattfindet.there For example, the multiple radar systems may be multiple Millimeter-wave radars or multiple laser radars (lidar) act or even a mixture of both types of systems. A combination of different radar systems is completely unproblematic, not according to the invention evaluated sensor-specific properties of the reflection signals but essentially just a test for the presence of reflection signals takes place as such.
Durch die Kombination zweier im Wesentlichen unabhängiger Verfahren wird in besonders vorteilhafter Weise eine sicherheitsrelevante Redundanz geschaffen.By The combination of two essentially independent procedures will be particularly beneficial advantageously created a security-relevant redundancy.
In besonders gewinnbringender Weise steht die erfindungsgemäße Vorrichtung mit wenigstens einem Fahrerassistenz system in Verbindung mittels welchem auf die Fahrdynamik Einfluss genommen werden kann und/oder Warnsignalgeber aktiviert werden können. So könnte beispielsweise bei Detektion und Identifikation eines im Fahrweg befindlichen beachtlichen Objekts ein Notbremssystem oder ein System zur Unfallfolgenminderung, („Pre-Safe") aktiviert werden. Auch ist es sehr wohl denkbar, dass der Fahrzeugführer oder im Umfeld des Fahrzeugs befindliche Personen durch akustische, optische oder haptische Warnsignalgeber vor einem beachtlichen Objekt im Fahrweg des Fahrzeuges gewarnt werden.In particularly profitable way is the device of the invention with at least one driver assistance system in conjunction using which can be influenced on the driving dynamics and / or Warning buzzer can be activated. For example, in detection and identification of a considerable object in the driveway an emergency braking system or an accident-prevention system ("Pre-Safe") are activated. Also, it is very possible that the driver or People in the vicinity of the vehicle by acoustic, optical or haptic warning buzzer in front of a respectable object in the Driveway of the vehicle to be warned.
Bei dem im Rahmen der Erfindung verwandten Sensorsystem zum Aussenden und Empfangen der elektromagnetischen Strahlung kann es sich gewinnbringend um ein Millimeterwellen-Radar oder aber auch um ein, insbesondere strahlschwenkendes, Laser-Radar (Lidar) handeln.at the related in the context of the invention sensor system for emitting and receiving the electromagnetic radiation may be profitable around a millimeter-wave radar or even one, in particular beam-swinging, laser radar (Lidar) act.
