Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren zum Betrieb eines Fahrzeuges anzugeben, auf dessen Dach eine durch eine Erfassungseinheit erfasste Dachlast angeordnet ist.Of the Invention is based on the object, an improved method to indicate the operation of a vehicle on the roof of a through a detection unit detected roof load is arranged.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The The object is achieved by the claim 1 specified characteristics solved. Advantageous developments The invention are the subject of the dependent claims.
Das erfindungsgemäße Verfahren zum Betrieb eines Fahrzeuges sieht vor, dass eine auf dem Fahrzeug angeordneten Dachlast mittels einer Erfassungseinheit erfasst wird und eine Steuereinheit vorgesehen ist, in welcher Kennfelder einer Fahrdynamikregelung hinterlegt sind, wobei bei erfasster Dachlast ein frührer Eingriff der Fahrdynamikregelung eingestellt wird. Erfindungsgemäß sind Kennfelder einer jeweiligen parametrierbaren aktiv verstellbaren Vorrichtung zur Beeinflussung eines Fahrverhaltens des Fahrzeuges hinterlegt, anhand welcher das Fahrverhalten des Fahrzeuges bei erfasster Dachlast gesteuert und/oder geregelt wird. Dabei werden insbesondere Kennfelder einer Luftfederung, einer verstellbaren Dämpfung, einer Lenkung und/oder einer Wankstabilisierung in der Steuereinheit hinterlegt, anhand derer das Fahrverhalten des Fahrzeuges gesteuert und/oder geregelt wird.The inventive method for operating a vehicle provides that a roof load arranged on the vehicle by means of a detection unit is detected and provided a control unit is, in which maps deposited a vehicle dynamics control are, with detected roof load a former intervention the vehicle dynamics control is set. According to the invention Maps of a respective parameterizable actively adjustable Device for influencing a driving behavior of the vehicle deposited, based on which the driving behavior of the vehicle at covered roof load is controlled and / or regulated. It will be in particular maps of an air suspension, an adjustable Damping, steering and / or roll stabilization stored in the control unit, on the basis of which the driving behavior the vehicle is controlled and / or regulated.
Dadurch, dass das Fahrverhalten des Fahrzeuges mit der von der Erfassungseinheit erfassten Dachlast anhand der Kennfelder gesteuert und/oder geregelt wird, werden Fahrzeugeigenschaften insbesondere für verschiedene Betriebszustände dahingehend verbessert, dass Fahrkomfort, Kraftstoffverbrauch und insbesondere eine Fahrsicherheit durch ein dem jeweiligen Betriebszustand angepasstes Fahrverhalten erhöht wird. Zusätzlich wird eine Wahrscheinlichkeit eines durch einen Fahrzeugführer verursachten Fahrfehlverhaltens verringert, da der Betriebsmodus bzw. die aktiv verstellbaren Vorrichtungen zur Beeinflussung des Fahrverhaltens einem entsprechenden Fahrzeugzustand angepasst sind.Thereby, that the driving behavior of the vehicle with that of the detection unit recorded roof load controlled by the maps and / or regulated will be, in particular for various vehicle characteristics Operating conditions improved so that ride comfort, Fuel consumption and in particular a driving safety by a the driving condition adapted to the respective operating state becomes. In addition, a probability of one through reduces a driver's driving behavior, because the operating mode or the actively adjustable devices for influencing the driving behavior of a corresponding vehicle state are adjusted.

Zu den parametrierbaren aktiv verstellbaren Vorrichtungen V1 bis Vn des Fahrzeuges zählen beispielsweise eine Fahrdynamikregelung V1, insbesondere ein elektronisches Stabilitätsprogramm, eine Luftfederung V2, eine Dämpfung V3, eine Lenkung V4, eine Wankstabilisierung V5, ein Federungssystem V6 einer aktiven Radaufhängung und/oder eine Motorsteuerung V7.To the parameterizable active variable devices V1 to Vn of the vehicle include, for example, a vehicle dynamics control V1, in particular an electronic stability program, an air suspension V2, a damping V3, a steering V4, a roll stabilization V5, a suspension system V6 active Wheel suspension and / or a motor control V7.
Beispielsweise ist eine Anzahl der Kennfelder K1 bis Kn für einen von der Auswerteeinheit erfassten ersten Fahrzeugzustand Z1, den ohne ermittelte Dachlast, hinterlegt. Darüber hinaus ist z. B. eine weitere Anzahl der Kennfelder K1 bis Kn für einen erfassten zweiten Fahrzeugzustand Z2, den einer ermittelten Dachlast, gespeichert.For example is a number of maps K1 to Kn for one of the evaluation unit detected first vehicle state Z1, the without determined roof load, deposited. In addition, z. B. a further number of maps K1 to Kn for a detected second vehicle state Z2, a determined roof load, saved.

Beispielsweise wird mittels der Steuerung und/oder Regelung veranlasst, dass die Fahrdynamikregelung V1 an den zweiten Fahrzeugzustand Z2 angepasst wird, dass die Luftfederung V2 abgesenkt wird, die Dämpfung V3 erhöht wird, eine Änderung des Eigenlenkverhaltens des Fahrzeuges durch eine geänderte Wankmomentverteilung vorgenommen wird, der Lenkmomentverlauf sowie eine Kennlinie des Gaspedals angepasst werden.For example is caused by the control and / or regulation that the Vehicle dynamics control V1 adapted to the second vehicle state Z2 is that the air suspension V2 is lowered, the damping V3 is increased, a change in the self-steering behavior of the vehicle due to a modified rolling moment distribution is made, the steering torque curve and a characteristic of the Accelerators are adjusted.
Darüber hinaus sieht das erfindungsgemäße Verfahren vor, dass in besonders vorteilhafter Weise veränderte Grenzwerte für das Abstandsregeltempomat eingestellt werden, da sich aufgrund der Erhöhung des Gesamtgewichtes des Fahrzeuges aufgrund der Dachlast das für die gewünschte Verzögerung nötige Bremsmoment verändert.About that In addition, the method according to the invention provides that in a particularly advantageous manner changed limits be set for the Abstandsregeltempomat, since due to the increase in the total weight of the vehicle due to the roof load that for the desired delay necessary braking torque changed.
Insbesondere wird der Grenzwert zur Einhaltung eines Sicherheitsabstandes besonders bevorzugt erhöht.Especially the limit for maintaining a safe distance becomes special preferably increased.
