Description
Die Erfindung betrifft ein Verfahren zur Steuerung eines Fahrwerksystems eines Kraftfahrzeuges, wobei eine Fahrwerksregeleinheit über eine Sensorik mit Fahrwerksparametern versorgt und anhand dieser Fahrwerksparameter eine Abstimmung von Fahrwerkskomponenten durch die Fahrwerksregeleinheit vorausschauend vorgenommen wird. Die Erfindung betrifft des Weiteren ein Fahrwerksregelsystem eines Kraftfahrzeuges, sowie ein Computerprogrammprodukt zur Umsetzung des erfindungsgemäßen Verfahrens bei diesem Fahrwerksregelsystem.The invention relates to a method for controlling a chassis system of a motor vehicle, wherein a chassis control unit is supplied via a sensor with chassis parameters and based on these chassis parameters, a vote of suspension components by the chassis control unit is made anticipatory. The invention further relates to a chassis control system of a motor vehicle, as well as a computer program product for implementing the method according to the invention in this chassis control system.
Im Bereich von Fahrwerksregelsystemen moderner Kraftfahrzeuge kommen insbesondere bei Oberklassefahrzeugen aktive Fahrwerksregelungen zur Anwendung, über welche Bewegungen eines Fahrzeugaufbaus im Hinblick auf Komfort und Fahrsicherheit möglichst optimal gestaltet werden können. Hierbei werden üblicherweise über Sensoren Parameter von Fahrwerkskomponenten erfasst und entsprechend dieser Parameter dann eine gezielte Verstellungen der jeweiligen Fahrwerkskomponenten durch eine Fahrwerksregeleinheit vorgenommen, um Bewegungen des Fahrzeugaufbaus, welche außerhalb definierter Grenzen liegen würden, zu unterbinden.In the field of suspension control systems of modern motor vehicles active chassis regulations are used in particular in luxury vehicles, over which movements of a vehicle body in terms of comfort and driving safety can be designed as optimally as possible. Here are usually detected by sensors parameters of suspension components and then made a targeted adjustments of the respective suspension components by a suspension control unit according to these parameters to prevent movements of the vehicle body, which would be outside defined limits.
Aus der
Ausgehend von einem Verfahren des Standes der Technik ist es die Aufgabe der vorliegenden Erfindung, ein Verfahren zur Steuerung eines Fahrwerksystems und ein entsprechendes Fahrwerksregelsystem zur Verfügung zu stellen, mittels welcher eine Anpassung der Abstimmung von Fahrwerkskomponenten an eine Beschaffenheit einer vorliegenden Fahrstrecke mit niedrigem Aufwand durchgeführt werden kann. Zudem sollte auch eine Anpassung an ein Fahrverhalten eines Fahrzeugführers möglich sein.Starting from a method of the prior art, it is the object of the present invention to provide a method for controlling a chassis system and a corresponding chassis control system, by means of which an adaptation of the coordination of suspension components to a condition of a present route is carried out with little effort can. In addition, an adaptation to a driving behavior of a driver should be possible.
Diese Aufgabe wird aus verfahrenstechnischer Sicht ausgehend vom Oberbegriff des Anspruchs 1 in Verbindung mit dessen kennzeichnenden Merkmalen gelöst. Aus vorrichtungstechnischer Sicht erfolgt eine Lösung der Aufgabe gemäß den Merkmalen des Anspruchs 5. Die darauffolgenden, abhängigen Ansprüche geben jeweils vorteilhafte Weiterbildungen der Erfindung wieder. Bezüglich eines Computerprogrammprodukts zur Ausführung der Erfindung, sowie eines Datenträgers zu dessen Speicherung wird auf die Ansprüche 6 und 7 verwiesen.This object is achieved from the procedural point of view, starting from the preamble of claim 1 in conjunction with its characterizing features. From a device technical point of view, a solution of the problem according to the features of
Die Erfindung umfasst die technische Lehre, dass Informationen bezüglich einer Beschaffenheit einer vorliegenden Fahrstrecke, sowie eines Verhaltens eines Fahrzeugführers an einer aktuellen Fahrzeug-Position durch eine Datenaufbereitungseinheit während eines Befahrens der Fahrstrecke gewonnen, mit der aktuellen Fahrzeug-Position verarbeitet und einem Informationsspeicher zugeführt werden. Diese Informationen werden dann bei einem erneuten Befahren der Fahrstrecke aus dem Informationsspeicher entnommen, um die Fahrwerkskomponenten zusätzlich zu den Fahrwerksparametern entsprechend der Informationen vorausschauend abzustimmen. Hierbei steht die Datenaufbereitungseinheit sowohl mit der Fahrwerksregeleinheit als auch mit einem Navigationssystem in Kontakt, welches zweckmäßigerweise die aktuelle Fahrzeug-Position ermittelt.The invention comprises the technical teaching that information regarding a condition of a present route, as well as behavior of a vehicle driver at a current vehicle position obtained by a data processing unit while driving the route, processed with the current vehicle position and fed to an information store. This information is then taken from the information store when driving again on the route to tune the suspension components in addition to the chassis parameters according to the information in a forward-looking manner. In this case, the data processing unit is in contact both with the chassis control unit and with a navigation system which expediently determines the current vehicle position.
Das Erfassen von Informationen über eine Beschaffenheit der vorliegenden Fahrstrecke, sowie eines Fahrverhaltens des Fahrzeugführers auf der selbigen gemeinsam mit dem anschließenden Abspeichern dieser Informationen bringt den Vorteil mit sich, dass die Fahrwerkskomponenten bei einem erneuten Befahren optimal auf die Fahrstrecke abgestimmt werden können. Denn hierdurch sind im Informationsspeicher positionsbezogene Daten hinsichtlich Fahrbahnbeschaffenheit und Fahrerwunsch abgelegt, über welche die einzelnen Fahrwerkskomponenten präzise und vorausschauend hinsichtlich Komfort und Sicherheit eingestellt werden können. Zudem lässt sich das System an den jeweiligen Fahrerwunsch anpassen, da ein positionsbezogenes Wissen über das Fahrverhalten eines Fahrzeugführers bereits abrufbar ist. Schließlich wirkt sich eine derartige Steuerung eines Fahrwerksystems positiv auf Stellenergien von Aktuatoren der Fahrwerkskomponenten, sowie auf deren Verschleiß aufgrund einer effektiveren Ansteuerung aus. Auch der, zum Abstimmen der Fahrwerkskomponenten benötigte Energiebedarf kann im Vorfeld besser abgeschätzt und dementsprechend das System frühzeitig auf die Energiebelastung eingestellt werden.The acquisition of information about a condition of the present route, as well as a driving behavior of the driver on the selbigen together with the subsequent storage of this information has the advantage that the suspension components can be optimally tuned to the route when driving again. Because this position-related data in terms of road condition and driver's request are stored in the information store over which the individual suspension components can be adjusted precisely and forward-looking in terms of comfort and safety. In addition, the system can be adapted to the respective driver's request, since a position-related knowledge about the driving behavior of a driver is already available. Finally, such control of a suspension system has a positive effect on body energies of actuators of the suspension components, as well as their wear due to a more effective control. Also, the energy required to tune the suspension components can be better estimated in advance and accordingly the system can be set early on the energy load.
Dem gegenüber zeichnet sich ein System des Standes der Technik durch eine sehr aufwendige Regelung aus. Denn eine Beschaffenheit der vorliegenden Fahrstrecke muss zunächst über eine Radareinrichtung erfasst und hieraus anschließend ein Steuersignal generiert werden. Entsprechend des Steuersignals muss die Fahrwerksregeleinheit im Anschluss eine Anpassung der Fahrwerkskomponenten vornehmen. Da das Zeitfenster zwischen Messung der Beschaffenheit der Fahrstrecke und Anpassung der Fahrwerkskomponenten sehr eng ist, müssen hierfür insgesamt sehr leistungsstarke Bauteile Anwendung finden, was den Herstellungsaufwand entsprechend erhöht. Zudem ist keine Anpassung an ein positionsbezogenes Fahrverhalten des Fahrzeugführers möglich.In contrast, a system of the prior art is characterized by a very complicated control. For a condition of the present route must first be detected by a radar device and from this subsequently a control signal can be generated. According to the control signal, the chassis control unit must be in Connection make an adjustment of the suspension components. Since the time window between measurement of the condition of the route and adaptation of the suspension components is very tight, very high-performance components must be used for this purpose overall, which increases the production costs accordingly. In addition, no adaptation to a position-related driving behavior of the driver is possible.
Gemäß einer vorteilhaften Ausführungsform der Erfindung werden die Informationen bei Befahren der Fahrstrecke durch Algorithmen mittels Beobachtung des Verhaltens des Kraftfahrzeuges und des Fahrzeugführers gewonnen und ständig aktualisiert. Zweckmäßigerweise wird das jeweilige Verhalten hierbei über die Fahrwerksparameter durch Analysealgorithmen erfasst, wobei hiermit gewonnene Daten anschließend einer Bewertung und Klassifizierung mittels Klassifizierungsalgorithmen unterzogen werden. Durch diese Maßnahme können somit die durch Sensoren der Fahrwerksregeleinheit gewonnenen Parameter direkt zur Ermittlung des Verhaltens des Kraftfahrzeuges und des Fahrzeugführers an der jeweiligen aktuellen Position herangezogen werden. Die Verarbeitung mittels Analyse- und Klassifizierungsalgorithmen vereinfacht dabei die Speicherung und das Wiederauffinden der jeweiligen Informationen im Informationsspeicher.According to an advantageous embodiment of the invention, the information obtained while driving the route by algorithms by observing the behavior of the motor vehicle and the driver and constantly updated. Expediently, the respective behavior is recorded here via the chassis parameters by analysis algorithms, with the data thus obtained being subsequently subjected to evaluation and classification by means of classification algorithms. By this measure, the parameters obtained by sensors of the chassis control unit can thus be used directly to determine the behavior of the motor vehicle and the driver at the respective current position. The processing by means of analysis and classification algorithms simplifies the storage and retrieval of the respective information in the information store.
Die erfindungsgemäße Lösung lässt sich auch als Computerprogrammprodukt verkörpern, welches, wenn es auf einem Prozessor der Fahrwerksregeleinheit läuft, den Prozessor softwaremäßig anleitet, die zugeordneten erfindungsgegenständlichen Verfahrensschritte durchzuführen.The solution according to the invention can also be embodied as a computer program product which, when running on a processor of the chassis control unit, instructs the processor by software to carry out the associated process steps according to the invention.
In diesem Zusammenhang gehört ein computerlesbares Medium zum Gegenstand der Erfindung, auf dem ein vorstehend beschriebenes Computerprogrammprodukt abrufbar gespeichert ist.In this context, a computer-readable medium is the subject of the invention, on which a computer program product described above is stored retrievably.
Weitere, die Erfindung verbessernde Maßnahmen werden nachstehend gemeinsam mit der Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung anhand einer Figur näher dargestellt.Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to a figure.
