Abstract
Description
Die Erfindung betrifft ein Verfahren und eine zur Durchführung des Verfahrens geeignet Vorrichtung zur fahrzeugbasierten Erfassung des quer zur Fahrtrichtung verlaufenden Höhenprofils einer Fahrbahn nach den Oberbegriffen der Patentansprüche 1 und 4.The The invention relates to a method and to carrying out the Method suitable device for vehicle-based detection the transverse to the direction of travel height profile of a road to the preambles of claims 1 and 4.
Durch Unebenheiten der Straße werden im Reifen u.a. Hub- und Längsschwingungen angeregt und über Reifen, Rad, Achse und Karosserieelemente bis zum Passagier geleitet. Die Anregungsfrequenzen hängen direkt vom Straßenprofil und der Fahrzeuggeschwindigkeit ab. Interessiert man sich zusätzlich für alle Freiheitsgrade der Anregung, benötigt man die 3D-Geometrie der Straßenoberfläche sowohl unter den vier Rädern als auch aufgelöst innerhalb der Reifenaufstandsfläche. Eine vollständige Simulation könnte dann sowohl die Drehmomente und Kräfte für jeden Reifen erzeugen und damit Nick-, Wank-, Giermomente als auch Längs-, Quer- und Hochkräfte auf das Fahrzeug wiedergeben. Vorraussetzung dazu ist eine zuverlässige Messung der Straßengeometrie, wie sie zum Beispiel von Schittenhelm und Ammon (Schittenhelm, H, Ammon, D., „Auf dem Wege zu lebensdauer- und komfortrelevanten 3-dimensionalen Fahrstrecken in der Fahrwerkssimulation", VDI-Bericht 1632, Reifen, Fahrwerk, Fahrbahn, Hannover 2001) beschrieben wird. Die dort gezeigte Messmethode ermöglicht zwar die Vermessung der Straßengeometrie über einen Ausgedehnten Bereich quer zur Straßenführung verlangt allerdings eine Absperrung der zu vermessenden Straßenfläche, was auf öffentlich zugänglichen Straßen nicht unproblematisch ist.By Bumps of the road are in the tire u.a. Lifting and longitudinal vibrations excited and over Tire, wheel, axle and body elements passed to the passenger. The excitation frequencies hang directly from the street profile and the vehicle speed. Are you also interested in all degrees of freedom the stimulus needed one the 3D geometry of the road surface both under the four wheels as well as dissolved within the tire contact patch. A complete simulation could then generate both the torques and forces for each tire and thus pitching, rolling, yawing moments as well as longitudinal, lateral and high forces play the vehicle. Prerequisite for this is a reliable measurement the road geometry, as, for example, Schittenhelm and Ammon (Schittenhelm, H, Ammon, D., "Up the way to life-time and comfort-relevant 3-dimensional routes in the suspension simulation ", VDI report 1632, tires, chassis, roadway, Hannover 2001) described becomes. Although the measuring method shown there allows the measurement the road geometry over one Extensive area across the street requires, however, a Shutting off the road surface to be surveyed, resulting in public accessible streets not unproblematic.
Aufgabe der Erfindung ist es, ein Verfahren und eine zur Durchführung des Verfahrens geeignete Vorrichtung zur fahrzeugbasierten Erfassung des quer zur Fahrtrichtung verlaufenden Höhenprofils einer Fahrbahn zu finden, welche es erlaubt bei einer an den Verkehrsfluss angepassten Überfahrt über eine Fahrbahn deren Oberflächenkontur hoch aufgelöst über einen ausgedehnten Bereich quer zur Fahrtrichtung zu vermessen.task The invention is a method and a for carrying out the Method suitable device for vehicle-based detection the transverse to the direction of travel height profile of a roadway find, which allows for a adapted to the traffic flow crossing over a Road surface whose surface contour high resolution over one extended area transverse to the direction of travel to measure.
Die Aufgabe wird durch ein Verfahren und ein zur Durchführung des Verfahrens geeignete Vorrichtung mit der Merkmalen der Patentansprüche 1 und 4 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.The Task is performed by a procedure and to carry out the Method suitable device with the features of claims 1 and 4 solved. Advantageous embodiments and further developments of the invention are in the subclaims described.
Bei der fahrzeug-basierten Erfassung des quer zur Fahrtrichtung verlaufenden Höhenprofils einer Fahrbahnoberfläche, wird mittels einer Sensoranordnung ein sich auf der Fahrbahnoberfläche senkrecht zur Fahrtrichtung erstreckender Messbereich erfasst. Hierdurch wird es möglich über den zeitlichen Verlauf der Messung, durch sukzessive Messaufnahmen das das Höhenprofil Fahrbahn parallel an mehreren Stellen entlang der Fahrtrichtung des Messfahrzeugs zu vermessen. In erfinderischer Weise wird die Fahrbahn zusätzlich mittels wenigstens einer weiteren Sensoranordnung vermessen wird. Hierzu ist diese weitere Sensoranordnung in Fahrtrichtung versetzt am Messfahrzeug angeordnet. Der Messbereich dieser Sensoranordnung erstreckt sich auf der Fahrbahnoberfläche ebenfalls senkrecht zur Fahrtrichtung des Messfahrzeuges. Die Ausrichtung der Sensoranordnungen ist ferner so organisiert, dass sie über den zeitlichen Verlauf der Messung hinweg einen überlappenden Oberflächenbereich der Fahrbahn vermessen. Auf diese Weise kann mittels dem Oberflächenmesssystem innerhalb des sich überlappenden Oberflächenbereichs eine redundante Messdatenerfassung erfolgen, ein Umstand welcher wie nachfolgend erläutert im Zusammenhang mit einer späteren Rekonstruk tion des Oberflächenprofils aus den Messdaten vorteilhaft genutzt werden kann.at the vehicle-based detection of the transverse to the direction of travel height profile a road surface, is by means of a sensor arrangement on the road surface perpendicular detected to the direction extending measuring range. This will it is possible over the temporal course of the measurement, by successive measurement recordings the height profile Lane parallel in several places along the direction of travel of the measuring vehicle. In an innovative way, the Roadway in addition is measured by means of at least one further sensor arrangement. For this purpose, this further sensor arrangement is offset in the direction of travel arranged on the measuring vehicle. The measuring range of this sensor arrangement extends on the road surface also perpendicular to Direction of travel of the measuring vehicle. The orientation of the sensor arrangements is also organized so that it is over the course of time The measurement is overlapping surface area measure the roadway. In this way, by means of the surface measuring system within the overlapping surface area a redundant data acquisition take place, a circumstance which as explained below in connection with a later Reconstruction of the surface profile can be used advantageously from the measured data.
