Aus der US 2005 / 0 206 235 A1 ist eine Stabilisierung eines Kraftfahrzeugs-Gespanns bekannt, wobei ein Differenzmoment zwischen den Rändern einer Achse des antreibenden Fahrzeugs aufgebracht wird.A stabilization of a motor vehicle combination is known from US 2005/0 206 235 A1, wherein a differential torque is applied between the edges of an axis of the driving vehicle.
Die
Der Erfindung liegt die Aufgabe zugrunde, eine alternative Vorrichtung bzw. ein alternatives Verfahren zur Stabilisierung eines Kraftfahrzeug-Gespanns anzugeben. Insbesondere soll die Vorrichtung bzw. das Verfahren derart ausgebildet sein, dass die Fahrzeug- bzw. Reisegeschwindigkeit durch die Stabilisierungsmaßnahmen möglichst nicht reduziert wird, beziehungsweise möglicht unbeeinträchtigt bleibt.The invention has for its object to provide an alternative device or an alternative method for stabilizing a motor vehicle combination. In particular, the device or the method should be designed in such a way that the vehicle or travel speed is as far as possible not reduced by the stabilization measures, or remains undisturbed as far as possible.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung zur Stabilisierung eines Kraftfahrzeug-Gespanns mit den Merkmalen des Anspruchs 1 und ein Verfahren zur Stabilisierung eines Kraftfahrzeug-Gespanns mit den Merkmalen des Anspruchs 6 gelöst, während in den Unteransprüchen bevorzugte Weiterbildungen der Erfindung angegeben sind.According to the invention the object is achieved by a device for stabilizing a motor vehicle combination with the features of claim 1 and a method for stabilizing a motor vehicle combination with the features of claim 6, while in the dependent claims preferred embodiments of the invention are given.
Die erfindungsgemäße Vorrichtung umfasst eine Momenten-Verteilungseinrichtung zur Verteilung von Moment zwischen den beiden Rädern einer gemeinsamen Anhängerachse, welche zwischen den Rädern der Anhängerachse angeordnet ist, eine Schlingerbewegungs-Erfassungseinrichtung zur Erfassung der Schlingerbewegung von Kraftfahrzeug und/oder Anhänger sowie eine Steuereinrichtung zur Steuerung und/oder Regelung (allgemein: Ansteuerung) der Momenten-Verteilungseinrichtung, derart, dass eine Verteilung von Momentenanteilen zwischen den Rädern einer gemeinsamen Anhängerachse erfolgt. Unter einer Momentenverteilung im Sinne der Erfindung ist die (Um-)Verteilung von Anteilen der Momente zu verstehen, die im Zeitpunkt der Verteilung an den Rädern einer gemeinsamen Anhängerachse vorhanden sind - dies wird dadurch erreicht, indem sich ein Rad an dem anderen zumindest teilweise abstützt und so quasi ein Teil von dessen Moment zugeteilt bekommt. Im Sinne der Erfindung wird unter einer Kopplung (der beiden Räder einer Anhängerachse) insbesondere eine kraft- und/oder formschlüssige Verbindung verstanden, derart, dass eine Abstützung eines Rades an dem anderen Rad möglich ist. Alternativ ist aber auch eine materialschlüssige Verbindung mit einem Verbindungselement mit veränderbaren Eigenschaften (wie einer steuerbaren Viskokupplung) denkbar.The device according to the invention comprises a torque distribution device for distributing torque between the two wheels of a common trailer axle, which is arranged between the wheels of the trailer axle, a rolling movement detection device for detecting the rolling movement of motor vehicle and / or trailer and a control device for controlling and / or or regulation (in general: activation) of the torque distribution device such that a distribution of torque components takes place between the wheels of a common trailer axle. A torque distribution in the sense of the invention means the (re-) distribution of portions of the moments which are present at the time of distribution on the wheels of a common trailer axle - this is achieved by one wheel being supported at least partially on the other and so a part of its moment gets assigned. For the purposes of the invention, a coupling (the two wheels of a trailer axle) is understood in particular to be a non-positive and / or positive connection, such that a support of one wheel on the other wheel is possible. Alternatively, however, a material connection with a connecting element with variable properties (such as a controllable viscous coupling) is conceivable.
Vorzugsweise ist die Momenten-Verteilungseinrichtung derart ausgebildet, dass jedem Rad (bzw. jeder Seite) der Anhängerachse ein steuerbares Trennkupplungsmittel (z.B. steuerbare Reibkupplung, steuerbare Viskokupplung oder dergleichen) zugeordnet ist, wobei zumindest ein, vorzugsweise beide Trennkupplungsmittel über die Steuereinrichtung in Abhängigkeit von vorbestimmten Betriebsparametern ansteuerbar ist/sind.Preferably, the torque distribution device is designed such that each wheel (or each side) of the trailer axle is associated with a controllable separating clutch means (eg controllable friction clutch, controllable viscous coupling or the like), wherein at least one, preferably both separating means via the control means in dependence on predetermined Operating parameters can be controlled / are.
Die Steuereinrichtung ist dabei derart ausgebildet, dass die Ansteuerung (von jeweils zumindest einem der beiden Trennkupplungsmittel) in Abhängigkeit von zumindest einem vorbestimmten, mit einer auftretenden Schlingerbewegung des ziehenden Kraftfahrzeugs und/oder des gezogenen Anhängers korrelierenden Betriebsparameter/Betriebsgröße erfolgt. Mit Vorteil korreliert die Betriebsgröße mit der Gierrate des Anhängers und/oder der aufgrund des schlingernden Anhängers erzeugten Gierbewegung des den Anhänger ziehenden Kraftfahrzeugs. Alternativ oder zusätzlich können noch die Querbeschleunigung, der Schwimmwinkel und/oder der zwischen Anhänger und Kraftfahrzeug auftretende Knickwinkel ausgewertet werden. Die Ansteuerung der Trennkupplungsmittel erfolgt derart, dass ein im Wesentlichen zur Schlingerbewegung gegenphasiges Giermoment erzeugt wird.The control device is designed in such a way that the activation (of at least one of the two separating coupling means) takes place as a function of at least one predetermined operating parameter / operating variable correlating with an occurring rolling movement of the towing motor vehicle and / or the towed trailer. Advantageously, the operational size correlates with the yaw rate of the trailer and / or the yawing motion of the trailer pulling vehicle due to the lurching trailer. Alternatively or additionally, the lateral acceleration, the slip angle and / or the bending angle occurring between the trailer and the motor vehicle can also be evaluated. The activation of the separating coupling means is effected in such a way that a yawing moment substantially opposite to the rolling movement is generated.
Des Weiteren umfasst die Erfindung ein Verfahren zur Stabilisierung eines Kraftfahrzeuggespanns, wobei das Kraftfahrzeuggespann mit Vorteil eine Vorrichtung umfasst, wie sie vorstehend beschrieben ist. Dabei wird durch das Erfassen einer, mit einer auftretenden Schlingerbewegung des Anhängers oder Kraftfahrzeugs korrelierenden Betriebsgröße, und das anschließende Ansteuern (steuern und/oder regeln) einer zwischen den Rädern einer gemeinsamen Anhängerachse angeordneten Momenten-Verteilungseinrichtung derart, dass der auftretenden Schlingerbewegung entgegengewirkt wird, eine entsprechende Stabilisierung des Kraftfahrzeuggespanns erreicht.Furthermore, the invention comprises a method for stabilizing a motor vehicle combination, wherein the motor vehicle combination advantageously comprises a device as described above. In this case, by detecting a, with an occurring rolling movement of the trailer or motor vehicle correlating operating size, and the subsequent driving (controlling and / or regulating) arranged between the wheels of a common trailer axle torque distribution device such that the occurring rolling motion is counteracted, a corresponding stabilization of the motor vehicle combination achieved.
In einer bevorzugten Ausführungsform erfolgt die Ansteuerung der Momenten-Verteilungseinrichtung derart, dass eine Stabilisierungsschwingung erzeugt wird, die zu der aufgrund der Schlingerbewegung erzeugten Schwingung im Wesentlichen gegenphasig ist, insbesondere um 180° Grad phasenverschoben ist. Dabei wird die Schlingerbewegung des Anhängers mit Vorteil direkt mittels einer mit dem Anhänger gekoppelten Gierratensensorik und/oder Knickwinkelsensorik (Sensorik zur Erfassung des zwischen der Fahrzeuglängsachse des ziehenden Fahrzeugs und der Längsachse des Anhängers entstehenden Winkels) und/oder Schwimmwinkelsensorik und/oder Querbeschleunigungssensorik erfasst. Zusätzlich kann im Zeitpunkt der Ansteuerung des mindestens einen Trennkupplungsmittels oder im Anschluss daran eine gesteuerte Abbremsung des Kraftfahrzeugs eingeleitet werden.In a preferred embodiment, the control of the torque distribution device takes place in such a way that a stabilizing oscillation is generated, which is substantially opposite in phase to the oscillation generated due to the rolling motion, in particular is phase-shifted by 180 °. The rolling movement of the trailer is advantageously detected directly by means of a yaw rate sensor coupled to the trailer and / or bending angle sensor (sensor for detecting the resulting between the vehicle longitudinal axis of the towing vehicle and the longitudinal axis of the trailer angle) and / or float angle sensor and / or lateral acceleration sensor. In addition, a controlled deceleration of the motor vehicle can be initiated at the time of activation of the at least one separating clutch means or subsequently.
