Description
Die Erfindung betrifft ein Verfahren zur Bestimmung einer Masse eines Fahrzeugs mit einem elektromechanischen Wankstabilisator. Ferner betrifft die Erfindung eine Vorrichtung zur Bestimmung der Masse des Fahrzeugs, umfassend den elektromechanischen Wankstabilisator.The invention relates to a method for determining a mass of a vehicle with an electromechanical roll stabilizer. Furthermore, the invention relates to a device for determining the mass of the vehicle, comprising the electromechanical roll stabilizer.
In der Regel weist jede Achse eines Kraftfahrzeugs einen Wankstabilisator auf, der nach dem Torsionsstabprinzip arbeitet. Der Wankstabilisator ist im Wesentlichen parallel zur Radachse angeordnet und an beiden Enden mit einer jeweiligen Radaufhängung verbunden. Dabei dient der Wankstabilisator zur Stabilisierung des Karosserieaufbaus gegenüber unerwünschten Wankbewegungen um die Längsachse, insbesondere die Rollachse des Kraftfahrzeugs. Solche Wankbewegungen treten beispielsweise bei Kurvenfahrt des Kraftfahrzeugs auf. Die Wankbewegung des Kraftfahrzeugs wird durch den Wankstabilisator beeinflusst, indem die Einfederbewegung der linken und rechten Radaufhängung einer Achse mithilfe des Wankstabilisators miteinander gekoppelt wird.As a rule, each axle of a motor vehicle has a roll stabilizer which operates on the torsion bar principle. The roll stabilizer is arranged substantially parallel to the wheel axle and connected at both ends with a respective suspension. In this case, the roll stabilizer is used to stabilize the body structure against unwanted rolling movements about the longitudinal axis, in particular the roll axis of the motor vehicle. Such rolling movements occur, for example, when cornering of the motor vehicle. The rolling motion of the motor vehicle is influenced by the roll stabilizer by the compression movement of the left and right wheel suspension of an axle is coupled together using the roll stabilizer.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Bestimmung einer Masse eines Fahrzeugs weiterzuentwickeln. Ferner besteht die Aufgabe der vorliegenden Erfindung auch darin eine Vorrichtung zur Bestimmung der Masse des Fahrzeugs zu schaffen.The object of the present invention is to develop a method for determining a mass of a vehicle. Furthermore, the object of the present invention is also to provide a device for determining the mass of the vehicle.
Im Rahmen des erfindungsgemäßen Verfahrens zur Bestimmung einer Masse eines Fahrzeugs mit einem elektromechanischen Wankstabilisator, werden zur Bestimmung der Masse des Fahrzeugs zumindest ein Drehmoment des elektromechanischen Wankstabilisators sowie ein Wankwinkel des Fahrzeugs und eine Querbeschleunigung des Fahrzeugs verwendet. Unter dem Drehmoment des elektromechanischen Wankstabilisators ist das Drehmoment zu verstehen, welches zur Wankstabilisierung des Fahrzeugs im Wankstabilisator erzeugt wird, insbesondere das Drehmoment, welches um die Rollachse des Fahrzeugs wirkt. Das Drehmoment des elektromechanischen Wankstabilisators wird in einem Aktuator des elektromechanischen Wankstabilisators, umfassend einen Elektromotor, eine Steuerungsvorrichtung und ein Getriebe, insbesondere ein Planetengetriebe, erzeugt.In the context of the inventive method for determining a mass of a vehicle with an electromechanical anti-roll bar, at least one torque of the electromechanical anti-roll bar and a roll angle of the vehicle and a lateral acceleration of the vehicle are used to determine the mass of the vehicle. The torque of the electromechanical roll stabilizer is to be understood as meaning the torque which is generated for roll stabilization of the vehicle in the roll stabilizer, in particular the torque which acts around the roll axis of the vehicle. The torque of the electromechanical roll stabilizer is generated in an actuator of the electromechanical roll stabilizer comprising an electric motor, a control device and a transmission, in particular a planetary gear.
Der Wankwinkel des Fahrzeugs ist von weiteren fahrzeugspezifischen Konstanten abhängig. Zur Bestimmung der Masse des Fahrzeugs wird eine erste Konstante, nämlich das Produkt aus einer Federsteifigkeit und dem Quadrat eines Federabstands von zwei Federn einer jeweiligen Radachse verwendet. Mithin wird zur Bestimmung der Masse des Fahrzeugs sowohl der Wankstabilisator an einer Vorderachse als auch der Wankstabilisator an einer Hinterachse des Fahrzeugs verwendet. Die Federsteifigkeit ist abhängig von der jeweiligen Feder eines jeweiligen Federbeins. Unter dem Federabstand von zwei Federn einer jeweiligen Radachse ist der Abstand zwischen zwei Federn einer jeweiligen Radachse quer zur Längsachse des Fahrzeugs zu verstehen. Vorzugsweise wird zur Bestimmung der Masse des Fahrzeugs eine zweite Konstante, nämlich ein Abstand zwischen einer Rollachse und einem Schwerpunkt des Fahrzeugs verwendet. Unter der Rollachse des Fahrzeugs ist im Wesentlichen die Längsachse des Fahrzeugs zu verstehen. Je höher das Fahrzeug ist, umso größer ist der Abstand zwischen der Rollachse und dem Schwerpunkt des Fahrzeugs. Ferner ist der Schwerpunkt des Fahrzeugs ein fiktiver Punkt, an dem sämtliche dynamische Kräfte des Fahrzeugs einwirken.The roll angle of the vehicle depends on further vehicle-specific constants. To determine the mass of the vehicle, a first constant, namely the product of a spring stiffness and the square of a spring spacing of two springs of a respective wheel axle is used. Thus, both the roll stabilizer on a front axle and the roll stabilizer on a rear axle of the vehicle are used to determine the mass of the vehicle. The spring stiffness is dependent on the respective spring of a respective shock absorber. The spring spacing of two springs of a respective wheel axle is to be understood as meaning the distance between two springs of a respective wheel axle transversely to the longitudinal axis of the vehicle. Preferably, a second constant, namely a distance between a roll axis and a center of gravity of the vehicle is used to determine the mass of the vehicle. Under the roll axis of the vehicle is substantially to understand the longitudinal axis of the vehicle. The higher the vehicle, the greater the distance between the roll axis and the center of gravity of the vehicle. Further, the center of gravity of the vehicle is a fictitious point on which all the dynamic forces of the vehicle act.
Die erfindungsgemäße Vorrichtung zur Bestimmung der Masse des Fahrzeugs, umfasst den elektromechanischen Wankstabilisator, der zur Wankstabilisierung des Fahrzeugs ein Drehmoment erzeugt, sowie Mittel zur Bestimmung des Wankwinkels des Fahrzeugs und Mittel zur Bestimmung der Querbeschleunigung des Fahrzeugs, wobei die Masse des Fahrzeugs zumindest mittels des Drehmoments des elektromechanischen Wankstabilisators sowie des Wankwinkels des Fahrzeugs und der Querbeschleunigung des Fahrzeugs bestimmbar ist.The device according to the invention for determining the mass of the vehicle comprises the electromechanical roll stabilizer, which generates a torque for roll stabilization of the vehicle, and means for determining the roll angle of the vehicle and means for determining the lateral acceleration of the vehicle, wherein the mass of the vehicle at least by means of the torque the electromechanical roll stabilizer and the roll angle of the vehicle and the lateral acceleration of the vehicle can be determined.
Insbesondere wird zur Bestimmung der Masse des Fahrzeugs das Drehmoment des elektromechanischen Wankstabilisators mit der ersten Konstante, nämlich dem Produkt aus der Federsteifigkeit und dem Quadrat des Federabstands von zwei Federn der jeweiligen Radachse addiert und mit dem Wankwinkel multipliziert. Das Ergebnis daraus wird durch das Produkt aus der zweiten Konstante und der Querbeschleunigung dividiert, wobei die zweite Konstante den doppelten Abstand zwischen der Rollachse und dem Schwerpunkt des Fahrzeugs darstellt. Mithin kann die Masse des Fahrzeugs unter Verwendung folgender Formel bestimmt werden: In particular, to determine the mass of the vehicle, the torque of the electromechanical roll stabilizer is added to the first constant, namely the product of the spring stiffness and the square of the spring pitch of two springs of the respective wheel axle and multiplied by the roll angle. The result of this is divided by the product of the second constant and the lateral acceleration, the second constant representing twice the distance between the roll axis and the center of gravity of the vehicle. Thus, the mass of the vehicle can be determined using the following formula:
Dabei steht mFahrzeug für die Masse des Fahrzeugs, φ für den Wankwinkel,
Vorzugsweise weist der elektromechanische Wankstabilisator einen Drehmomentsensor zur Messung eines Drehmoments am elektromechanischen Wankstabilisator auf. Mittels des Drehmomentsensors lässt sich das vom Aktuator erzeugte Drehmoment am Wankstabilisator besonders genau messen, wodurch die Masse des Fahrzeugs exakter bestimmt werden kann.The electromechanical roll stabilizer preferably has a torque sensor for measuring a torque on the electromechanical roll stabilizer. By means of the torque sensor, the torque generated by the actuator on the roll stabilizer can be measured particularly accurately, whereby the mass of the vehicle can be determined more accurately.
Bevorzugt ist der Wankwinkel des Fahrzeugs über einen jeweiligen Radhub an einem jeweiligen Rad des Fahrzeugs bestimmbar. Insbesondere weist das Fahrzeug zwei Achsen mit jeweils zwei Rädern auf. Sofern die beiden Räder einer ersten Fahrzeugseite den gleichen Radhub aufweisen wie die beiden Räder einer zweiten Radachse beträgt der Wankwinkel 0°. Eine Zu- oder Abnahme des Radhubs auf einer einzigen Fahrzeugseite führt zu einer Zunahme des Wankwinkels des Fahrzeugs und somit zu einem Rollen des Fahrzeugs um die Rollachse.The roll angle of the vehicle can preferably be determined via a respective wheel stroke on a respective wheel of the vehicle. In particular, the vehicle has two axles with two wheels each. If the two wheels of a first side of the vehicle have the same Radhub as the two wheels of a second wheel axle, the roll angle is 0 °. An increase or decrease of the wheel stroke on a single vehicle side leads to an increase in the roll angle of the vehicle and thus to a rolling of the vehicle about the roll axis.
Ferner bevorzugt ist die Querbeschleunigung des Fahrzeugs mittels eines Sensorelements zur Messung der Querbeschleunigung des Fahrzeugs bestimmbar. Die Querbeschleunigung des Fahrzeugs wird insbesondere von einem ESP-System zur elektronischen Stabilitätskontrolle des Fahrzeugs bestimmt.Further preferably, the lateral acceleration of the vehicle can be determined by means of a sensor element for measuring the transverse acceleration of the vehicle. The lateral acceleration of the vehicle is determined in particular by an ESP system for electronic stability control of the vehicle.
Vorzugsweise ist ein Rechnersystem zur Bestimmung und Überwachung der Masse des Fahrzeugs vorgesehen. Alle zur Bestimmung der Masse des Fahrzeugs benötigten Messwerte werden in dem Rechnersystem zusammengetragen, um daraus die Masse des Fahrzeugs zu bestimmen. Mithin lässt sich mit dem elektromechanischen Wankstabilisator auf einfache Weise die Masse des Fahrzeugs bestimmen.Preferably, a computer system for determining and monitoring the mass of the vehicle is provided. All measurements needed to determine the mass of the vehicle are collected in the computer system to determine the mass of the vehicle. Consequently, the mass of the vehicle can be determined in a simple manner with the electromechanical anti-roll bar.
Weitere die Erfindung verbessernde Maßnahmen werden nachstehend gemeinsam mit der Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung anhand der einzigen Figur näher dargestellt. Die einzige Figur zeigt eine stark vereinfachte, schematische Schnittdarstellung zur Veranschaulichung des Aufbaus einer Radachse, umfassend eine Vorrichtung zur Bestimmung einer Masse eines Fahrzeugs.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 the single figure. The single figure shows a highly simplified, schematic sectional view illustrating the structure of a wheel axle, comprising a device for determining a mass of a vehicle.

Im Wesentlichen wird zur Bestimmung der Masse des Kraftfahrzeugs das Drehmoment des elektromechanischen Wankstabilisators mit der ersten Konstante addiert und mit dem Wankwinkel multipliziert. Das Ergebnis daraus wird durch das Produkt aus der zweiten Konstante und der Querbeschleunigung dividiert. Diese Rechenoperation übernimmt das Rechnersystem
