Bei dem erfindungsgemäßen Verfahren zum Betrieb eines Fahrzeuges werden mittels einer oder mehrerer Erfassungseinheiten ein in Fahrtrichtung vor dem Fahrzeug befindliches Objekt und ein Abstand des Fahrzeuges zu dem Objekt erfasst, wobei anhand des Objektes und des Abstandes ein Rückhaltesystem für Fahrzeuginsassen gesteuert wird. Erfindungsgemäß wird das Objekt dreidimensional vermessen, aus dieser Messung ermittelte Objektdaten werden mit einer Kontur des Fahrzeuges verglichen und aus dem Vergleich wird ein Kollisionszeitpunkt des Fahrzeuges mit dem Objekt abgeleitet, wobei anhand des Kollisionszeitpunktes Auslöseparameter, insbesondere ein Auslösezeitpunkt und/oder eine Auslösecharakteristik, des Rückhaltesystemes ermittelt und eingestellt werden. Aufgrund der dreidimensionalen Vermessung des Objektes und dem Vergleich mit der Kontur des Fahrzeuges ist eine sehr genaue Modellierung, d. h. eine sehr genaue Ermittlung des Kollisionszeitpunktes und in einer Weiterbildung des erfindungsgemäßen Verfahrens eines Kollisionsortes, realisierbar. Aus dieser sehr genauen Modellierung resultiert in besonders Gewinn bringender Weise die Möglichkeit, die Auslöseparameter des Rückhaltesystemes derart einzustellen, dass ein optimaler Schutz für die Insassen des Fahrzeuges sichergestellt ist.In the method according to the invention for operating a vehicle, an object located in front of the vehicle in the direction of travel and a distance of the vehicle to the object are detected by means of one or more detection units, wherein a restraint system for vehicle occupants is controlled on the basis of the object and the distance. According to the invention, the object is measured three-dimensionally, object data determined from this measurement are compared with a contour of the vehicle and a collision time of the vehicle with the object is derived from the comparison, triggering parameters, in particular a triggering time and / or a tripping characteristic, of the restraint system based on the collision time be determined and set. Because of dreidi dimensional measurement of the object and the comparison with the contour of the vehicle is a very accurate modeling, ie a very accurate determination of the collision time and in a development of the method according to the invention of a collision location, realized. From this very precise modeling results in a particularly profit-making way, the possibility of setting the trigger parameters of the restraint system such that optimum protection for the occupants of the vehicle is ensured.
Die erfindungsgemäße Vorrichtung zum Betrieb eines Fahrzeuges umfasst eine oder mehrere Erfassungseinheiten zur Erfassung eines in Fahrtrichtung vor dem Fahrzeug befindlichen Objektes und eines Abstandes des Fahrzeuges zu dem Objekt. Die Vorrichtung umfasst weiterhin eine Steuereinheit, mittels derer anhand des Objektes und des Abstandes ein Rückhaltesystem für Fahrzeuginsassen steuerbar ist. Erfindungsgemäß sind die Erfassungseinheiten derart ausgebildet, dass das Objekt dreidimensional vermessbar ist. Es ist eine Verarbeitungseinheit vorgesehen, mittels der anhand dieser Messung ermittelte Objektdaten mit einer Kontur des Fahrzeuges vergleichbar sind. Aus dem Vergleich ist ein Kollisionszeitpunkt des Fahrzeuges mit dem Objekt ableitbar und anhand des Kollisionszeitpunktes sind Auslöseparameter, insbesondere ein Auslösezeitpunkt und/oder eine Auslösecharakteristik, des Rückhaltesystemes ermittelbar und einstellbar.The Inventive device for operating a Vehicle comprises one or more detection units for detection an object located in front of the vehicle in the direction of travel and a distance of the vehicle to the object. The device comprises furthermore a control unit, by means of which by means of the object and the distance a restraint system for vehicle occupants is controllable. According to the invention, the detection units designed such that the object is measured in three dimensions. It is a processing unit provided by means of this measurement determined object data with a contour of the vehicle are comparable. The comparison is a collision time of the vehicle with the object derivable and based on the collision time are Tripping parameters, in particular a tripping time and / or a tripping characteristic of the restraint system determinable and adjustable.
Die Erfassungseinheiten umfassen gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung zumindest einen Radarsensor, zumindest einen Lidarsensor und/oder zumindest ein stereoskopisches Kamerasystem. Bei einer Kombination von zwei oder mehr Erfassungseinheiten, welche vorzugsweise verschiedene Erfassungsbereiche aufweisen, die sich zumindest teilweise überschneiden, ist eine sehr genaue Erfassung der Umgebung des Fahrzeuges realisierbar, welche die Voraussetzung für die oben genannte Modellierung darstellt.The Detection units comprise according to an advantageous Embodiment of the device according to the invention at least one radar sensor, at least one lidar sensor and / or at least a stereoscopic camera system. In a combination of two or more detection units, which are preferably different Have detection areas that overlap at least partially is a very accurate detection of the environment of the vehicle feasible, which is the prerequisite for the above modeling represents.

Da die Schutzwirkung verschiedener Rückhaltesysteme, beispielsweise eines Airbags, nur dann optimal ist, wenn diese genau zum richtigen Zeitpunkt bezüglich des Aufpralls ausgelöst werden, ist aufgrund der sehr genauen Ermittlung des Kollisionszeitpunktes eine maximale Schutzwirkung mittels der Rückhaltesysteme erzielbar. Somit ist beispielsweise eine unzureichende Schutzwirkung des Airbags bei einer zu frühen oder zu späten Auslösung vermeidbar.There the protective effect of various restraint systems, for example of an airbag, only then is optimal, if this at exactly the right time with respect to the impact is due to the very accurate determination of the collision time one maximum protection can be achieved by means of the restraint systems. Thus, for example, an insufficient protective effect of the airbag Avoid too early or too late.
Auch ist es aufgrund der Erfindung möglich, den Airbag schon kurz vor dem Aufprall, beispielsweise 30 bis 70 ms vor dem Kollisionszeitpunkt, d. h. wenn sichergestellt ist, dass der Aufprall unvermeidbar ist, auszulösen, um eine langsamere und somit weniger aggressive Entfaltung des Airbags zu ermöglichen.Also it is possible because of the invention, the airbag already shortly before the impact, for example 30 to 70 ms before the collision time, d. H. if it is ensured that the impact is unavoidable, trigger a slower and thus less aggressive To allow deployment of the airbag.
