Abstract
Description
Die Erfindung betrifft ein Verfahren zur Stabilisierung eines Fahrzeuges bei Aquaplaning.The The invention relates to a method for stabilizing a vehicle at aquaplaning.
Bei einem Aufschwimmen eines Rades eines Fahrzeuges auf einem Flüssigkeitsfilm, so genanntem Aquaplaning, verliert das Rad den Fahrbahnkontakt. Am aufgeschwommenen Rad sind keine Kräfte mehr übertragbar, wodurch die Lenkbarkeit des Fahrzeuges stark beeinträchtigt wird oder sogar vollständig unmöglich wird, so dass der Fahrer die Kontrolle über das Fahrzeug verlieren kann. Durch unterschiedlich große Schwallwiderstände an den beiden Vorderrädern kann es außerdem zu Gierstörungen kommen.at a floating of a wheel of a vehicle on a liquid film, so-called aquaplaning, the wheel loses the road contact. On the floated wheel, no forces are transferable, whereby the steerability of the vehicle severely impaired becomes or even completely impossible, so that the driver loses control of the vehicle can. By different sized surge resistance On the two front wheels it can also Yeast problems come.
Aus
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur verbesserten Stabilisierung eines Fahrzeuges bei Aquaplaning anzugeben.Of the Invention is based on the object, a method for improved Indicate stabilization of a vehicle in aquaplaning.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, welches die in Anspruch 1 angegebenen Merkmale aufweist.The The object is achieved by a method which has the features specified in claim 1 having.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Verfahren zur Stabilisierung eines Fahrzeuges bei bestehendem oder bevorstehendem Aquaplaning wird ein Sollverhalten des Fahrzeuges bestimmt und ein Giermoment des Fahrzeuges derart erzeugt, dass ein Istverhalten des Fahrzeuges dem Sollverhalten angenähert wird.at the method according to the invention for stabilization of a vehicle with existing or forthcoming aquaplaning a target behavior of the vehicle is determined and a yaw moment of the vehicle generated such that an actual behavior of the vehicle approximates the target behavior.
Dabei umfasst das Sollverhalten bevorzugt eine Sollgierrate und/oder einen Sollschwimmwinkel des Fahrzeuges. Dabei bezeichnet der Schwimmwinkel einen Winkel zwischen einer Längsachse und einer momentanen Bewegungsrichtung des Fahrzeuges.there the target behavior preferably comprises a desired yaw rate and / or a Sollschwimmwinkel the vehicle. The slip angle is called an angle between a longitudinal axis and a momentary one Direction of movement of the vehicle.
Durch das an dem Sollverhalten ausgerichtete Giermoment wird das Verhalten des Fahrzeuges bei bestehendem oder bevorstehendem Aquaplaning vorteilhaft stabilisiert. Die Lenkbarkeit des Fahrzeuges wird erhöht, so dass das Fahrzeug auch bei Aquaplaning lenkbar bleibt. Insbesondere werden Störimpulse kompensiert, die beispielsweise durch einen einseitig wirkenden Schwallwiderstand erzeugt werden. Dadurch kann ein Fahrer des Fahrzeuges bei bestehendem oder bevorstehendem Aquaplaning dem Straßenverlauf folgen und nötigenfalls vorhandenen Hindernissen ausweichen.By the yaw moment aligned with the desired behavior becomes the behavior the vehicle in existing or forthcoming aquaplaning advantageous stabilized. The steerability of the vehicle is increased so that the vehicle remains steerable even when aquaplaning. Especially interference pulses are compensated, for example, by a unidirectional surge resistance can be generated. This can a driver of the vehicle in existing or forthcoming aquaplaning the Follow the course of the road and, if necessary, existing Dodge obstacles.
Durch die dadurch erreichte Stabilisierung des Fahrzeuges können außerdem Panik- und Überreaktionen des Fahrers aufgrund instabilen Fahrverhaltens des Fahrzeuges bei Aquaplaning verhindert, reduziert oder kompensiert werden, wodurch die Fahrsicherheit weiter erhöht wird.By the resulting stabilization of the vehicle can also panic and overreactions of the driver due to unstable driving behavior of the vehicle during aquaplaning prevents, reduces or compensates, thereby improving driving safety is further increased.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass das Giermoment durch Abbremsen eines Hinterrades des Fahrzeuges erzeugt wird.A advantageous embodiment of the invention provides that the yaw moment is generated by braking a rear wheel of the vehicle.
Die Abbremsung eines Hinterrades ist vorteilhaft, da die Hinterräder in der Spur der Vorräder laufen und dadurch bei Aquaplaning weniger stark auf dem Flüssigkeitsfilm aufschwimmen, so dass sie mehr Bodenhaftung als die Vorderräder aufweisen und eine höhere Bremswirkung als die Vorderräder vermitteln können.The Deceleration of a rear wheel is beneficial because the rear wheels in the track of the Vorräder run and thereby aquaplaning Floating less strongly on the liquid film, so that they have more grip than the front wheels and give a higher braking effect than the front wheels can.
Die Erzeugung eines Giermomentes durch Abbremsen eines Hinterrades hat ferner den Vorteil, dass durch den Bremseingriff das Fahrzeug gleichzeitig verzögert wird. Selbst wenn eine vollständige Stabilisierung des Fahrzeuges nicht mehr möglich ist, werden die Geschwindigkeit und damit auch die Energie des Fahrzeuges abgebaut. Dadurch können wenigstens die Folgen eines Unfalls reduziert werden, wenn der Unfall trotz des Eingriffs nicht mehr zu verhindern ist.The Generation of a yawing moment by braking a rear wheel has Furthermore, the advantage that the vehicle at the same time by the braking intervention is delayed. Even if complete stabilization the vehicle is no longer possible, the speed and thus also reduced the energy of the vehicle. This can at least the consequences of an accident can be reduced if the accident despite the intervention is no longer to prevent.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens liegt darin, dass es mit bereits bekannten Fahrwerktechnologien wie dem ABC-System (ABC = Active Body Control) und Fahrerassistenzsystemen wie dem ESP (ESP = Elektronisches Stabilitätsprogramm bzw. Electronic Stability Program) durchgeführt werden kann. Insbesondere sind somit für ein mit derartigen Systemen ausgestattetes Fahrzeug zur Durchführung des Verfahrens keine zusätzlichen Aktoren erforderlich.One further advantage of the method according to the invention This is because it works with already known suspension technologies such as the ABC system (ABC = Active Body Control) and driver assistance systems such as the ESP (ESP = Electronic Stability Program or Electronic Stability Program) can be performed. In particular, thus are for one with such systems equipped vehicle for carrying out the method no additional actuators required.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung werden im Folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf eine Zeichnung beschrieben. Dabei zeigt:Further Advantages, features and details of the invention are described below based on embodiments with reference to a drawing described. Showing:

dem Bremseingriff wird dabei ausschließlich ein Umfangskrafteffekt
genutzt, um eine Gierreaktion des Fahrzeuges
Zur Regelung der Gierrate wird eine gemessene Gierrate von der Sollgierrate subtrahiert. Für die resultierende Gierratenabweichung werden ein unterer und ein oberer Schwellwert vorgegeben, durch die ein Regelbereich eingegrenzt wird. Innerhalb dieses Regelbereiches wird folgendermaßen eine normierte Regeldifferenz gebildet:
- – Ist die Gierratenabweichung kleiner oder gleich dem unteren Schwellwert, so wird der normierten Regeldifferenz der Wert Null zugewiesen.
- – Ist die Gierratenabweichung größer oder gleich dem oberen Schwellwert, so wird der normierten Regeldifferenz der Wert Eins zugewiesen.
- – Zwischen dem unteren und dem oberen Schwellwert steigt die normierte Regeldifferenz geeignet, beispielsweise linear, von Null auf Eins an.
- - If the yaw rate deviation is less than or equal to the lower threshold value, then the normalized control difference is assigned the value zero.
- - If the yaw rate deviation is greater than or equal to the upper threshold, the normalized control difference is assigned the value one.
- Between the lower and the upper threshold value, the normalized control difference increases suitably, for example linearly, from zero to one.
Nach
der Normierung wird die Regeldifferenz mit einem Aquaplaningflag
multipliziert, das den Wert Eins hat, wenn an mindestens einem Rad
Die
mit dem Aquaplaningflag multiplizierte normierte Regeldifferenz
