Abstract

The passenger car has a steering wheel that is displaced in interior of vehicle by a control unit. The control unit brings the steering wheel with an intended reverse travel of the car in a different position than driving forward. The intended reverse movement by the reverse gear is performed by the driver. The control unit brings the steering wheel to the position that is closer to the driver and/or higher than the steering wheel position. A belt tensioner is controlled such that the seat belt has large belt backlash.

Description

Die Erfindung betrifft einen Personenkraftwagen mit einem hinsichtlich seiner Position im Fahrzeug-Innenraum durch eine Steuereinheit motorisch verlagerbaren Lenkrad. Zum Stand der Technik wird neben der DE 103 23 975 B4 insbesondere auf die EP 1 261 505 B1 verwiesen.The invention relates to a passenger car with a motor in terms of its position in the vehicle interior by a control unit displaceable steering wheel. The state of the art is in addition to the DE 103 23 975 B4 especially on the EP 1 261 505 B1 directed.

Automatisch, d. h. durch eine Steuereinheit verstellbare, d. h. unterschiedliche im Fahrzeug-Innenraum positionierbare Lenkräder sind grundsätzlich bekannt, wobei die oben zweitgenannte Schrift vorschlägt, die Höhe bzw. Längsposition des Lenkrads indirekt, nämlich nach erfolgter Einstellung der Sitzposition, in Abhängigkeit von der Position eines Körperteils des Fahrers einzustellen. Hierbei erfolgt eine automatische einmalige „Grund”-Einstellung, nachdem der Fahrer im Fahrzeug Platz genommen hat.Automatic, d. H. adjustable by a control unit, d. H. different in the vehicle interior positionable steering wheels are basically known, the second above-mentioned document suggests adjusting the height or longitudinal position of the steering wheel indirectly, namely after the adjustment of the seat position, depending on the position of a body part of the driver. This is an automatic one-time "basic" setting after the driver has taken place in the vehicle.

Vorliegend soll eine weitere Maßnahme zur Steigerung des Fahr-Komforts für einen Fahrer eines Personenkraftwagens aufgezeigt werden (= Aufgabe der vorliegenden Erfindung). Die Lösung dieser Aufgabe ist für einen Personenkraftwagen nach dem Oberbegriff des Anspruchs 1 dadurch gekennzeichnet, dass die Steuereinheit das Lenkrad bei einer beabsichtigten Rückwärtsfahrt des Personenkraftwagens in eine andere Position als bei Vorwärtsfahrt bringt. Vorteilhafte Weiterbildungen sind Inhalt der Unteransprüche.In the present case, a further measure to increase the driving comfort for a driver of a passenger car to be shown (= object of the present invention). The solution to this problem is for a passenger car according to the preamble of claim 1, characterized in that the control unit brings the steering wheel in an intended reversing of the passenger car in a different position than when driving forward. Advantageous developments are content of the dependent claims.

Erfindungsgemäß wird das Lenkrad eines PKW's bei beabsichtigter Rückwärtsfahrt anders und dabei selbstverständlich für die Bedienung durch den Fahrer günstiger positioniert als bei Vorwärtsfahrt. Üblicherweise dreht bei Rückwärtsfahrt des Fahrzeugs der Fahrer seinen Kopf nach hinten, um durch die Fzg.-Heckscheibe hindurch die Rückwärtsfahrt zu kontrollieren. Dabei verdreht der Fahrer auch geringfügig seinen Oberkörper und bringt damit die Oberarme in eine andere Position, was sich naturgemäß auf die Handhabung des Lenkrads mit den Händen auswirkt. Ferner spielen weitere Randbedingungen, die für die Lenkrad-Position bei Vorwärtsfahrt des Fahrzeugs zu berücksichtigen sind, so insbesondere ein möglichst freier Blick auf die Armaturentafel, bei Rückwärtsfahrt des Fahrzeugs keine Rolle, so dass es bei Rückwärtsfahrt des Fahrzeugs durchaus günstig sein kann, wenn das Lenkrad geringfügig höher und/oder näher zum Fahrer hin positioniert wird als bei Vorwärtsfahrt des Fahrzeugs.According to the steering wheel of a car in intentional reverse driving is different and thereby, of course, positioned for the operation by the driver cheaper than when driving forwards. Usually, when the vehicle is reversed, the driver turns his head back to control the reverse drive through the vehicle rear window. The driver also slightly turns his upper body and thus brings the upper arms in a different position, which naturally affects the handling of the steering wheel with his hands. Furthermore, play further boundary conditions that are to be considered for the steering wheel position when driving forward of the vehicle, so in particular a free view of the dashboard when reversing the vehicle is not important, so that it can be quite favorable when reversing the vehicle when the Steering wheel is slightly higher and / or positioned closer to the driver than during forward travel of the vehicle.

In diesem Zusammenhang sei ausdrücklich darauf hingewiesen, dass vorliegend zwar ein Personenkraftwagen mit einer das Lenkrad unterschiedlich positionierenden Steuereinheit beansprucht wird, dass daneben oder anstelle eines solchen Anspruchs ohne nennenswerte inhaltliche Änderung ebenso gut ein Verfahren zum automatischen Positionieren eines motorisch verstellbaren Lenkrads eines Personenkraftwagens durch eine Steuereinheit beansprucht werden könnte, wobei das Lenkrad bei einer beabsichtigten Rückwärtsfahrt des Personenkraftwagens in eine andere Position als bei Vorwärtsfahrt gebracht wird. Entsprechendes gilt für die im weiteren erläuterten Unteransprüche.In this context, it is expressly understood that although a passenger car with a steering wheel differently positioning control unit is claimed that next to or instead of such a claim without significant change in content as well a method for automatically positioning a motorized steering wheel of a passenger car by a control unit could be claimed, wherein the steering wheel is brought in an intended reverse drive of the passenger car in a different position than when driving forward. The same applies to the subclaims explained below.

Zuvor sei jedoch der Vollständigkeit halber noch weiterer Stand der Technik genannt, nämlich die DE-OS 21 13 770 , die ein landwirtschaftliches Nutzfahrzeug beschreibt, dessen Lenkrad zusammen mit dem Sitz für eine Rückwärtsfahrt anders positioniert wird als bei Vorwärtsfahrt. Da bei dieser Schrift der Sitz und damit quasi auch der Fahrer um 180° gedreht wird, kann diese Schrift jedoch keine Anregung für die vorliegende Erfindung geben. Gleiches gilt für die DE 103 23 975 B4 , in der vorgeschlagen wird, bei Rückwärtsfahrt des Fahrzeugs eine andere Lenkübersetzung zwischen Lenkrad und den lenkbaren Rädern einzustellen als bei Vorwärtsfahrt.However, for the sake of completeness, further prior art is mentioned above, namely the DE-OS 21 13 770 , which describes an agricultural utility vehicle, the steering wheel is positioned together with the seat for a reverse drive than when driving forward. However, since in this document the seat and thus, so to speak, the driver is rotated by 180 °, this document can give no suggestion for the present invention. The same applies to the DE 103 23 975 B4 , in which it is proposed to set a different steering ratio between the steering wheel and the steerable wheels when reversing the vehicle than when driving forward.

Vorzugsweise kann eine beabsichtigte Rückwärtsfahrt aus dem Einlegen des Rückwärtsgangs durch den Fahrer abgeleitet werden und/oder es kann die besagte andere Position näher beim Fahrer und/oder höher liegen als die Lenkrad-Position bei Vorwärtsfahrt. Im übrigen kann zusätzlich ein dem Fachmann bekannter Gurtstraffer solchermaßen angesteuert werden, dass der Sicherheitsgurt bei der Rückwärtsfahrt des Fahrzeugs ein größeres Gurtspiel besitzt, um dem Fahrer die erforderliche Bewegungsfreiheit zum „Nach-hinten-Blicken” zu gewähren, wozu lediglich beispielhalber noch auf die DE 10 2007 059 898 A1 verwiesen wird. Schließlich kann auch eine insbesondere motorische Verstellung des Fahrersitzes oder von Bestandteilen desselben geeignet angesteuert werden, derart, dass der Sitz und/oder dessen Lehne und/oder eine verstellbare Kopfstütze in eine für eine Rückwärtsfahrt günstigeren Position gebracht wird. Neben einer Veränderung der Sitzhöhe oder der Sitzlehnen-Neigung am Fahrersitz kann aber auch eine verstellbare Kopfstütze im Hinblick auf eine verbesserte Sicht nach hinten selbsttätig verlagert werden.Preferably, an intended reverse drive may be derived from the engagement of the reverse gear by the driver and / or the said other position may be closer to the driver and / or higher than the steering wheel position when driving forward. Moreover, a belt tensioner known to those skilled in the art may additionally be controlled in such a way that the seat belt has a greater belt play when the vehicle is reversing in order to give the driver the necessary freedom of movement for "rear-facing", for which purpose only for the sake of example DE 10 2007 059 898 A1 is referenced. Finally, a particular motor adjustment of the driver's seat or components of the same can be suitably controlled, such that the seat and / or the backrest and / or an adjustable headrest is brought into a more favorable for a reverse position. In addition to a change in the seat height or the seat back tilt on the driver's seat but also an adjustable headrest with regard to improved visibility to the rear can be moved automatically.
