Abstract
Durch ein gezieltes Einleiten eines Giermoments, z. B. durch das Abbremsen eines Fahrzeugrades soll eine Rotation des Fahrzeugs erzielt werden, damit das Fahrzeug aus einem kritischen Bereich mit einem Hindernis weggedreht werden kann.By a targeted introduction of a yaw moment, z. B. by the deceleration of a vehicle wheel, a rotation of the vehicle is to be achieved so that the vehicle can be rotated away from a critical area with an obstacle.
Description
Die Erfindung bezieht sich auf ein Verfahren zur Beeinflussung einer Fahrbewegung eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1. The invention relates to a method for influencing a driving movement of a motor vehicle according to the preamble of claim 1.
Aus der
Aufgabe der Erfindung ist es, ein Verfahren zur Beeinflussung einer Fahrbewegung eines Kraftfahrzeugs beim Erkennen von einem Hindernis zu schaffen, bei der ein im Fahrzeug vorhandenes elektronisches Stabilitätsprogramm sowie eine vorhandene Sensorik verwendet werden. The object of the invention is to provide a method for influencing a driving movement of a motor vehicle when detecting an obstacle, in which an existing electronic stability program in the vehicle and an existing sensors are used.
Diese Aufgabe wird erfindungsgemäß durch die Verfahrensmerkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche. This object is achieved by the method features of claim 1. Further advantageous features include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass durch einen Eingriff in ein elektronisches Stabilitätsprogramm des Fahrzeugs im Falle einer Kollision mit einem Hindernis ein gezieltes Giermoment am Fahrzeug ausgeübt wird. Dies wird nach der Erfindung erreicht, indem über das elektronische Fahrzeug-Stabilitätsprogramm im Falle der Kollision mit dem Hindernis automatisch ein Giermoment um die Hochachse des Fahrzeugs ausgeübt wird, um eine Überdeckung zwischen Fahrzeug und Hindernis zu minimieren bzw. zu vermeiden. The advantages achieved by the invention are that a targeted yaw moment is exerted on the vehicle by an intervention in an electronic stability program of the vehicle in the event of a collision with an obstacle. This is achieved according to the invention by automatically exerting a yaw moment about the vertical axis of the vehicle via the electronic vehicle stability program in the event of collision with the obstacle in order to minimize or avoid overlapping between the vehicle and the obstacle.
Ferner ist nach der Erfindung vorgesehen, dass bei einem Crash mittels einer Sensorik des Fahrzeugs eine Sensierung des Auslösezeitpunkts für die Ausübung des Giermoments festgestellt und danach das Giermoment am Fahrzeug eingestellt wird. Es wird somit das Giermoment über das Fahrzeug-Stabilitätsprogramm nach dem Feststellen des Auslösezeitpunkts über die Sensorik ausgeübt. Furthermore, it is provided according to the invention that in a crash by means of a sensor system of the vehicle detects a sensing of the triggering time for the exercise of the yawing moment and then the yaw moment is set on the vehicle. Thus, the yaw moment is exerted via the vehicle stability program after the determination of the triggering time via the sensor system.
Die Ausübung des Giermoments erfolgt am Fahrzeug durch ein Abbremsen eines Fahrzeugrades über eine Bremseinrichtung, das sich diagonal zum Hindernis an einer Hinterachse des Fahrzeugs befindet. Der Giermomenteingriff wird jeweils durch die Bremseinrichtung an einem einzelnen Fahrzeugrad durchgeführt. Die Abbremsung eines Fahrzeugrades entsprechend der Lage des Hindernisses bewirkt ein Verdrehen des Fahrzeugs um seine Hochachse, so dass eine Rotation erzeugt wird, die das Fahrzeug aus dem kritischen Bereich wegdreht. The exercise of the yawing moment takes place on the vehicle by a braking of a vehicle wheel via a braking device, which is located diagonally to the obstacle on a rear axle of the vehicle. The yaw moment intervention is performed by the braking device on a single vehicle wheel. The deceleration of a vehicle wheel according to the position of the obstacle causes the vehicle to rotate about its vertical axis, so that a rotation is generated which turns the vehicle away from the critical area.
Somit hat der Giermomenteingriff alleinig das Ziel, ein Herausdrehen des Fahrzeugs aus dem kritischen Bereich zwischen dem Fahrzeug und dem Hindernis zu bewirken, damit eine geringe oder keine Überdeckung zwischen Fahrzeug und Hindernis entstehen kann. Hierdurch wird auch eine Intrusion in den Fahrzeuginnenraum vermieden. Thus, the yaw moment intervention has the sole purpose of causing the vehicle to spin out of the critical area between the vehicle and the obstacle so that little or no overlap between the vehicle and the obstacle can occur. As a result, an intrusion into the vehicle interior is avoided.
Der Bremseingriff auf das Fahrzeugrad zur Erreichung des Giermoments erfolgt automatisch bei einem Auftreffen oder vor dem Auftreffen auf das Hindernis. Somit ist der Fahrer in seiner Lenkbewegung entlastet bzw. das Verdrehen des Fahrzeugs erfolgt automatisch ohne Mitwirkung des Fahrers. Gegebenenfalls kann eine Lenkbewegung des Fahrers übersteuert werden. The braking intervention on the vehicle wheel to achieve the yawing moment takes place automatically when hitting or before hitting the obstacle. Thus, the driver is relieved in his steering movement or the rotation of the vehicle takes place automatically without the involvement of the driver. Optionally, a steering movement of the driver can be overridden.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Die Zeichnung zeigt ein Fahrzeug mit einem Bremseingriff auf ein hinteres Fahrzeugrad zur Erzeugung eines Giermoments, wobei das Fahrzeugrad diagonal zu einem Hindernis angeordnet ist. An embodiment of the invention is illustrated in the drawing and will be described in more detail below. The drawing shows a vehicle with a braking engagement with a rear vehicle wheel for generating a yaw moment, wherein the vehicle wheel is arranged diagonally to an obstacle.
