Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen.The invention relates to a method and a device for damping a steering wheel movement of a vehicle in jerky movements.
In Kraftfahrzeugen ist es ein allgemeines Ziel, die Auswirkungen einer Kollision auf die Insassen des Fahrzeugs soweit wie möglich zu reduzieren. Um bei Unfällen das Verletzungsrisiko für einen Fahrer eines Fahrzeugs zu reduzieren, wird derzeit beispielsweise die Gefährdung durch eine in den Fahrgastraum eindringende Lenksäule und die daraus folgende Bewegung der gesamten Lenkung berücksichtigt. Die Lenksäule kann dabei mit Gelenken und Teleskop-Elementen versehen sein, so dass sie bei einem Aufprall nachgeben kann. Diese Anordnung sorgt so für eine weitgehende Entkoppelung der Lenkradbewegung von der einer Deformation eines Vorbaus des Fahrzeugs.In motor vehicles, it is a general goal to reduce as much as possible the effects of a collision on the occupants of the vehicle. In order to reduce the risk of injury to a driver of a vehicle in accidents, for example, the risk is currently taken into account by a penetrating into the passenger compartment steering column and the consequent movement of the entire steering. The steering column can be provided with joints and telescopic elements, so that they can yield in an impact. This arrangement thus ensures a substantial decoupling of the steering wheel movement from the deformation of a stem of the vehicle.
Die
Die
Bei derartigen Vorrichtungen wird jedoch nicht berücksichtigt, dass eine starke Bewegung des Lenkrads durch äußere Einwirkungen auf die Räder eines Fahrzeugs, wie beispielsweise ein Unfall oder eine Hindernisüberfahrt, entstehen kann. Bei unsachgemäßen Halten des Lenkrads durch einen Fahrer eines Fahrzeugs, beispielsweise einem Hereingreifen in das Lenkrad, können durch die von außen verursachte Bewegung des Lenkrads Verletzungen, beispielsweise an den Fingern, Händen oder Armen, des Fahrers entstehen. Das Einleiten dieser Drehbewegung wird nicht durch die derzeitigen Insassenschutzvorkehrungen abgedeckt oder kann bereits in Situationen entstehen, beispielsweise Überfahrt eines Bordsteins oder andere Hindernisse, bei denen eine Insassenschutzvorkehrung nicht aktiv eingreift.In such devices, however, is not considered that a strong movement of the steering wheel by external effects on the wheels of a vehicle, such as an accident or an obstacle crossing, may arise. Improper holding of the steering wheel by a driver of a vehicle, such as a Hereingreifen in the steering wheel, caused by the externally caused movement of the steering wheel injury, for example, on the fingers, hands or arms of the driver. The initiation of this rotational movement is not covered by current occupant protection arrangements or may already arise in situations such as curb crossing or other obstacles where an occupant protection arrangement is not actively engaged.
Somit liegt der Erfindung die Aufgabe zugrunde ein Verfahren und eine Vorrichtung zu schaffen, eine verbesserte Insassenschutzvorkehrung für den Fahrer eines Fahrzeugs bei einer Lenkradbewegung bei einem Unfall oder einem Radaufschlag bereitzustellen.Thus, the invention has for its object to provide a method and an apparatus to provide an improved occupant protection arrangement for the driver of a vehicle in a steering wheel movement in an accident or a Radaufschlag.
Diese Aufgabe wird durch ein Verfahren zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen gemäß Anspruch 1 und einer Vorrichtung Verfahren zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen gemäß Anspruch 7 gelöst.This object is achieved by a method for damping a steering wheel movement of a vehicle in jerky movements according to claim 1 and a device method for damping a steering wheel movement of a vehicle in jerky movements according to
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous embodiments of the invention are specified in the dependent claims.
Erfindungsgemäß wird ein Verfahren zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen bereitgestellt, wobei eine Krafteinwirkung auf Vorderräder des Fahrzeugs anhand einer Bewegung eines Lenkrads des Fahrzeugs erfasst wird. Die Intensität der Krafteinwirkung auf die Vorderräder des Fahrzeugs wird ermittelt und in Abhängigkeit der ermittelten Intensität der Krafteinwirkung eine der Krafteinwirkung gegenwirkende Kraft erzeugt.According to the invention, a method is provided for damping a steering wheel movement of a vehicle in jerky movements, wherein a force is detected on the front wheels of the vehicle based on a movement of a steering wheel of the vehicle. The intensity of the force acting on the front wheels of the vehicle is determined and generates a force counteracting the force as a function of the determined intensity of the force.
Durch das Erzeugen der der Krafteinwirkung gegenwirkenden Kraft kann bereits bei Bewegungen der Vorderräder, welche noch nicht die Intensität der Bewegung bei einem Unfall erreicht, der Fahrer des Fahrzeugs geschützt werden, indem sich das Lenkrad nicht ruckartig dreht.By generating the force acting against the force force, the driver of the vehicle can already be protected during movements of the front wheels, which have not yet reached the intensity of the movement in the event of an accident, in that the steering wheel does not rotate jerkily.
Die Krafteinwirkung kann durch eine elektromechanische Lenkung am Lenkrad des Fahrzeugs erzeugt werden, wobei erkannt werden kann, dass die Krafteinwirkung asymmetrisch ist. Das Erzeugen der gegenwirkenden Kraft kann in Abhängigkeit davon geschehen, ob die Krafteinwirkung asymmetrisch ist.The force can be generated by an electromechanical steering on the steering wheel of the vehicle, it can be seen that the force is asymmetric. Generating the counteracting force may be dependent on whether the force is asymmetric.
Die Intensität der Krafteinwirkung kann beispielsweise durch eine Auswertung eines Handmoments am Lenkrad des Fahrzeugs ermittelt werden.The intensity of the force can be determined for example by an evaluation of a manual torque on the steering wheel of the vehicle.
Die Dämpfung wird zum Beispiel zeitlich dosiert. The damping is dosed, for example, in time.
Die gegenwirkende Kraft kann in Abhängigkeit davon erzeugt werden, ob eine Unfallsituation erkannt wird.The counteracting force can be generated depending on whether an accident situation is detected.
Ein weiterer Aspekt der vorliegenden Erfindung ist die Bereitstellung eine Vorrichtung zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen. Die Vorrichtung umfasst Sensormittel zum Erfassen einer Krafteinwirkung auf Vorderräder des Fahrzeugs anhand einer Bewegung eines Lenkrads eines Fahrzeugs und zum Ermitteln der Intensität der Krafteinwirkung auf die Vorderräder des Fahrzeugs. Des Weiteren umfasst die Vorrichtung eine Steuerungseinheit zum Erzeugen von einer gegenwirkenden Kraft in Abhängigkeit der ermittelten Intensität der Krafteinwirkung.Another aspect of the present invention is to provide a device for damping a steering wheel movement of a vehicle in jerky movements. The apparatus includes sensor means for sensing a force on front wheels of the vehicle based on a movement of a steering wheel of a vehicle and for determining the intensity of the force on the front wheels of the vehicle. Furthermore, the device comprises a control unit for generating a counteracting force as a function of the determined intensity of the force.
Die Sensormittel können einen Lenkwinkelsensor zum Erfassen der Krafteinwirkung umfassen. The sensor means may comprise a steering angle sensor for detecting the force.
Die Sensormittel können einen Drehmomentsensor zum Ermitteln der Intensität der Krafteinwirkung umfassen.The sensor means may comprise a torque sensor for determining the intensity of the force.
Des Weiteren können bereits aus dem Stand der Technik bekannte vorhandene Sensormittel zur Erfassung eines Fahrzeugszusammenstoßes ergänzend verwendet werden, um eine Fehlinformation an die Steuerungseinrichtung zu vermeiden.Furthermore, already known from the prior art existing sensor means for detecting a vehicle collision can be used in addition to avoid misinformation to the control device.
Die Vorrichtung kann zum Durchführen des Verfahrens zur Dämpfung einer Lenkradbewegung eines Fahrzeugs bei stoßartigen Bewegungen ausgestaltet sein.The device may be configured for performing the method for damping a steering wheel movement of a vehicle in jerky movements.
