Description
Die Erfindung betrifft ein Fahrerassistenzsystem zum teilautomatischen Kuppeln eines zweispurigen Kraftfahrzeugs mit einem Anhänger, welches die Querführung des rückwärts zum Anhänger hin fahrenden Kraftfahrzeugs durch selbsttätige Einstellung eines geeigneten Fahrzeug-Lenkwinkels unter Auswertung der Signale einer Sensoreinrichtung übernimmt. Zum Stand der Technik wird auf die
Aus der genannten Schrift ist eine Vorrichtung zur Unterstützung des Ankuppelns eines Anhängers eines Kraftfahrzeugs und ein entsprechendes Verfahren mit den im Oberbegriff des vorliegenden Anspruchs 1 angegebenen Merkmalen bekannt. Mittels einer in dieser Schrift näher beschriebenen Sensorvorrichtung kann die Position der Deichselspitze bzw. Anhängerkupplung des Anhängers in Relation zur Anhängerkupplung des Kraftfahrzeugs bestimmt werden und es wird beim Rückwärtsfahren des Kraftfahrzeugs vom Fahrerassistenzsystem die sog. Querführung des Fahrzeugs übernommen, indem dessen Lenksystem gesteuert durch eine elektronische Steuereinheit vorzugsweise durch den elektrischen Servomotor des Lenksystems solchermaßen eingestellt wird, dass die Anhängerkupplung des Kraftfahrzeugs in diejenige Position geführt wird, in der sie mit der Anhängerkupplung des Anhängers gekuppelt werden kann.From the cited document, a device for supporting the coupling of a trailer of a motor vehicle and a corresponding method with the features specified in the preamble of the present claim 1 is known. By means of a sensor device described in more detail in this document, the position of the tiller tip or trailer hitch of the trailer can be determined in relation to the trailer hitch of the motor vehicle and it is taken when reversing the motor vehicle from the driver assistance system, the so-called. Transverse guidance of the vehicle by its steering system controlled by an electronic Control unit is preferably adjusted by the electric servomotor of the steering system such that the trailer hitch of the motor vehicle is guided in the position in which it can be coupled to the trailer hitch of the trailer.
Hiermit soll eine Maßnahme zur weiteren Steigerung des Komforts in Verbindung mit dem Kuppeln eines Anhängers an ein Kraftfahrzeug aufgezeigt werden (= Aufgabe der vorliegenden Erfindung).This is a measure to further increase the comfort in connection with the coupling of a trailer to a motor vehicle be shown (= object of the present invention).
Die Lösung dieser Aufgabe ist für ein Fahrerassistenzsystem nach dem Oberbegriff des Anspruchs 1 dadurch gekennzeichnet, dass das Fahrerassistenzsystem auch die Längsführung des sich dem Anhänger näherenden Fahrzeugs durch geeignete Eingriffe in das Antriebssystem und Bremssystem des Kraftfahrzeugs übernimmt. Nach einer vorteilhaften Weiterbildung kann das Fahrerassistenzsystem auch von einer sich außerhalb des Kraftfahrzeugs befindlichen Person aktivierbar sein.The solution to this problem is for a driver assistance system according to the preamble of claim 1, characterized in that the driver assistance system also takes over the longitudinal guidance of the vehicle approaching the trailer by suitable interventions in the drive system and braking system of the motor vehicle. According to an advantageous development, the driver assistance system can also be activated by a person outside the motor vehicle.
Im Stand der Technik muss der Fahrer des Kraftfahrzeugs mit dessen Annäherung an den Anhänger das Fahrzeug zunächst geringfügig abbremsen und dann exakt in dem Moment zum Stillstand bringen, in dem sich die Anhängerkupplungen des Fahrzeugs und des Anhängers in einer für das Aneinander-Kuppeln geeigneten Position befinden. Dies mag manch einen Fahrer überfordern, insbesondere jedoch unterscheiden sich die Reaktionszeiten verschiedener Fahrer auf ein in der
Mit der vorliegenden Erfindung hingegen wird der Fahrer nicht nur weiter entlastet, sondern es kann das Kraftfahrzeug vorteilhafterweise in der exakten Soll-Position zum Stillstand gebracht werden, wenn auch die sog. Längsführung des Kraftfahrzeugs, d. h. dessen Fortbewegung zum Anhänger hin sowie insbesondere dessen Abbremsvorgang zum Stillstand exakt in der gewünschten Position ebenso wie die Querführung vom Fahrerassistenzsystem übernommen wird. Dies ist bei modernen Kraftfahrzeugen einfach möglich, da diese bereits mit anderen Systemen ausgerüstet sind, die auf die Längsdynamik des Fahrzeugs einwirken, d. h. die das Fahrzeug beschleunigen und bis zum Stillstand abbremsen können.By contrast, with the present invention, the driver is not only further relieved, but the motor vehicle can advantageously be brought to a standstill in the exact desired position, even if the so-called. Longitudinal guide of the motor vehicle, d. H. whose locomotion to the trailer and in particular its deceleration to standstill exactly in the desired position as well as the lateral guidance is taken from the driver assistance system. This is easily possible with modern motor vehicles because they are already equipped with other systems that affect the longitudinal dynamics of the vehicle, i. H. which accelerate the vehicle and can decelerate to a stop.
Was ein neben den soeben genannten und dem Fachmann bekannten Systemen zur Längsführung des Fahrzeugs weiterhin im Rahmen der vorliegenden Erfindung erforderliches System zur Querführung des Fahrzeugs sowie eine geeignete Sensoreinrichtung zum Ermitteln derjenigen Zielposition des Kraftfahrzeugs, in welcher die Anhängerkupplung des Anhängers mit derjenigen des Fahrzeugs kuppelbar ist, betrifft, so kann hierfür auf die in der besagten
Zur weiteren Steigerung des Komforts kann ein erfindungsgemäßes Fahrerassistenzsystem von einer sich außerhalb des Kraftfahrzeugs befindlichen Person aktiviert werden und somit die Positionierung des Kraftfahrzeugs in einer Ziel-Position, in der die Anhängerkupplung des Anhängers mit derjenigen des Fahrzeugs kuppelbar ist, von außerhalb des Fahrzeugs in Gang gesetzt werden. Wenn ein Fahrer an sein Kraftfahrzeug einen abgestellten Anhänger ankuppeln möchte, so muss er das Fahrzeugs lediglich eine geringe Distanz zum Anhänger annähern und kann danach aussteigen, beispielsweise um die Anhängerkupplung des Anhängers vorzubereiten oder indem eine Diebstahl-Verhinderungsvorrichtung entfernt wird. Danach kann der Fahrer mit einer geeigneten Fernbedienung, die sich vorzugsweise an bzw. in seinem Fahrzeugschlüssel befinden kann, die exakte Positionierung des Kraftfahrzeugs durch das erfindungsgemäße Fahrerassistenzsystem starten, um schließlich, wenn das Fahrzeug in der Zielposition zum Stillstand gekommen ist, sofort die beiden Anhängerkupplungen miteinander zu verbinden.To further enhance comfort, a driver assistance system according to the invention can be activated by a person located outside the motor vehicle and thus the positioning of the motor vehicle in a target position, in which the trailer hitch with that of the vehicle can be coupled, from outside the vehicle in motion be set. When a driver wants to couple a parked trailer to his motor vehicle, he only has to approach the vehicle a short distance from the trailer and can then get out, for example, to prepare the trailer hitch or by removing a theft prevention device. Thereafter, the driver with a suitable remote control, which may preferably be located on or in his vehicle key, the exact positioning of the motor vehicle by the driver assistance system according to the invention start to finally, when the vehicle in the Target position has come to a standstill, immediately connect the two trailer hitches.
Nach einer vorteilhaften Erweiterung kann durch ein Niveauregulierungs-System des Kraftfahrzeugs dessen Anhängerkupplung für ein Unterfahren der Anhängerkupplung des Anhängers zunächst abgesenkt und nach erfolgtem Positionieren für den Kuppelvorgang zur Anhängerkupplung des Anhängers hin angehoben werden. Damit ist ein automatisches Ankuppeln möglich, wonach der Fahrer lediglich noch das Bugrad hochziehen und den elektrischen Anhängerstecker verbinden muss.According to an advantageous extension can be lowered by a level control system of the motor vehicle whose trailer hitch for underrunning the trailer hitch of the trailer first and raised after successful positioning for the coupling process to the trailer hitch of the trailer. This automatic coupling is possible, after which the driver only has to pull up the nose wheel and connect the electric trailer plug.
