  • a motor vehicle door assembly has been found that finds particular application in coupe-vehicle body shapes application.
  • motor vehicle doors are provided with great extension in the longitudinal direction of the motor vehicle, which considerably complicates the closing operation when the user is in the sitting position in the vehicle interior. This is because the door operating handle located on the inside of the motor vehicle door, via which the operating force of the user is introduced into the motor vehicle door, is often far away from the user when the power vehicle door is open. This must perform significant dislocations depending on the size of the body to reach the door handle.

  • the known motor vehicle door assembly with the associated method for motorized adjustment offers a high level of user comfort, since the user does not have to apply an actuating force during the closing operation.
  • the implementation effort for the known motor vehicle door assembly is considerable. This is due first of all to the fact that, during the closing process, immediately before reaching the closed position, there are high counter torques which arise due to the engagement between a motor vehicle lock assigned to the motor vehicle door and a closing part assigned to the motor vehicle body as well as through sealing back pressures.
  • a closing aid is used as a rule, which takes over the adjustment of the motor vehicle door from a pre-closed position immediately preceding the closed position into the closed position.

Subsequently, the user adjusts the motor vehicle door in a second section of the closing operation manually and largely free of the door drive, this manual adjustment is an adjustment of the vehicle door from the comfort open position in the direction of the closed position.
  • the closing operation for the motor vehicle door is therefore subdivided into two sections, of which only the first section comprises a motorized adjustment of the motor vehicle door in the above sense.

Description

Die Erfindung betrifft ein Verfahren zur motorischen Verstellung einer Kraftfahrzeugtür gemäß dem Oberbegriff von Anspruch 1 sowie eine Kraftfahrzeugtüranordnung mit einer Kraftfahrzeugtür gemäß dem Oberbegriff von Anspruch 9.The invention relates to a method for the motorized adjustment of a motor vehicle door according to the preamble of claim 1 and to a motor vehicle door arrangement with a motor vehicle door according to the preamble of claim 9.

Der Begriff "Kraftfahrzeugtür" ist vorliegend umfassend zu verstehen. Er umfasst sowohl Seitentüren als auch Hecktüren, Heckklappen, Heckdeckel, Motorraumklappen oder Laderaumklappen. Bei der Kraftfahrzeugtür kann es sich um eine Schwenktür oder um eine Schiebetür handeln. Im Folgenden ist durchweg von einer als Schwenktür ausgestalteten Seitentür die Rede, was nicht beschränkend zu verstehen ist.The term "motor vehicle door" is comprehensively understood in the present case. It includes side doors as well as rear doors, tailgates, trunk lids, engine compartment flaps or cargo compartment flaps. The motor vehicle door may be a hinged door or a sliding door. In the following, there is always talk of a swing door designed as a side door, which is not to be understood as limiting.

Mit der in den letzten Jahren immer weiter angestiegenen Funktionsdichte in Kraftfahrzeugtüren ist auch das Gewicht der Kraftfahrzeugtüren immer weiter angestiegen. Dies führt dazu, dass insbesondere der manuelle Schließvorgang, den der Benutzer vom Fahrzeuginnenraum aus in der sitzenden Position vollzieht, in Abhängigkeit von den jeweiligen geometrischen Randbedingungen unkomfortabel sein kann.With the ever-increasing functional density in motor vehicle doors in recent years, the weight of motor vehicle doors has also risen ever further. As a result, in particular, the manual closing operation, which the user performs from the vehicle interior in the seated position, can be uncomfortable depending on the respective geometric boundary conditions.

Als besonders unkomfortabel hat sich eine Kraftfahrzeugtüranordnung herausgestellt, die insbesondere bei Coupé-Kraftfahrzeugkarosserieformen Anwendung findet. Bei einer solchen Anordnung sind Kraftfahrzeugtüren mit großer Erstreckung in Längsrichtung des Kraftfahrzeugs vorgesehen, was den Schließvorgang bei im Fahrzeuginnenraum in der sitzenden Position befindlichem Benutzer erheblich erschwert. Dies liegt daran, dass der auf der Innenseite der Kraftfahrzeugtür befindliche Türbetätigungsgriff, über den an sich die Betätigungskraft des Benutzers in die Kraftfahrzeugtür eingleitet wird, bei geöffneter Kraftfahurzeugtür oftmals weit vom Benutzer entfernt ist. Dieser muss je nach Körpergröße erhebliche Verrenkungen durchführen, um den Türbetätigungsgriff zu erreichen.Particularly uncomfortable, a motor vehicle door assembly has been found that finds particular application in coupe-vehicle body shapes application. In such an arrangement, motor vehicle doors are provided with great extension in the longitudinal direction of the motor vehicle, which considerably complicates the closing operation when the user is in the sitting position in the vehicle interior. This is because the door operating handle located on the inside of the motor vehicle door, via which the operating force of the user is introduced into the motor vehicle door, is often far away from the user when the power vehicle door is open. This must perform significant dislocations depending on the size of the body to reach the door handle.

Einen Lösungsansatz bietet die Ausstattung der Kraftfahrzeugtür mit einem Türantrieb, durch den die Kraftfahrzeugtür im Rahmen eines motorischen Schließvorgangs von der Offenstellung in Schließrichtung verstellbar ist. Die bekannte Kraftfahrzeugtüranordnung ( DE 20 2004 016 542 U1 ), von der die Erfindung ausgeht, zeigt einen solchen Türantrieb, der neben der motorischen Verstellung eine rein manuelle Verstellung der Kraftfahrzeugtür erlaubt.One approach provides the equipment of the motor vehicle door with a door drive, through which the motor vehicle door is adjustable in the closing direction of the open position in the context of a motor closing operation. The known motor vehicle door arrangement ( DE 20 2004 016 542 U1 ), from which the invention proceeds, shows such a door drive, which allows a purely manual adjustment of the motor vehicle door in addition to the motorized adjustment.

Zwar bietet die bekannte Kraftfahrzeugtüranordnung mit dem dazugehörigen Verfahren zur motorischen Verstellung einen hohen Benutzungskomfort, da der Benutzer keine Betätigungskraft während des Schließvorgangs aufbringen muss. Allerdings ist der Realisierungsaufwand für die bekannte Kraftfahrzeugtüranordnung beträchtlich. Dies liegt zunächst daran, dass es beim Schließvorgang unmittelbar vor Erreichen der Schließstellung zu hohen Gegenmomenten kommt, die durch den Eingriff zwischen einem der Kraftfahrzeugtür zugeordneten Kraftfahrzeugschloss und einem der Kraftfahrzeugkarosserie zugeordneten Schließteil sowie durch Dichtungsgegendrücke entstehen.Although the known motor vehicle door assembly with the associated method for motorized adjustment offers a high level of user comfort, since the user does not have to apply an actuating force during the closing operation. However, the implementation effort for the known motor vehicle door assembly is considerable. This is due first of all to the fact that, during the closing process, immediately before reaching the closed position, there are high counter torques which arise due to the engagement between a motor vehicle lock assigned to the motor vehicle door and a closing part assigned to the motor vehicle body as well as through sealing back pressures.

Im Hinblick auf die obigen Gegenmomente wird in der Regel eine Schließhilfe eingesetzt, die die Verstellung der Kraftfahrzeugtür von einer der Schließstellung unmittelbar vorgelagerten Vorschließstellung in die Schließstellung übernimmt. Dabei kann es sich um einen Antrieb der Schlossfalle des Kraftfahrzeugschlosses oder um einen Antrieb des Schließkeils handeln. Die letztgenannte Variante ist in der DE 103 61 843 A2 erläutert.In view of the above counter-moments a closing aid is used as a rule, which takes over the adjustment of the motor vehicle door from a pre-closed position immediately preceding the closed position into the closed position. This may be a drive of the latch of the motor vehicle lock or a drive of the closing wedge. The latter variant is in the DE 103 61 843 A2 explained.

Ferner ist eine Kraftfahrzeugtüranordnung bekannt ( DE 100 23 259 B4 ), bei der die selbsttätige Verstellung der Kraftfahrzeugtür einerseits durch den Türantrieb und andererseits, kurz vor Erreichen der Schließstellung, durch Gewichtskraft erfolgt. Auch hier ist der Realisierungsaufwand beträchtlich.Furthermore, a motor vehicle door arrangement is known (US Pat. DE 100 23 259 B4 ), in which the automatic adjustment of the motor vehicle door on the one hand by the door drive and on the other hand, shortly before reaching the closed position, by weight. Again, the implementation effort is considerable.

Schließlich ist eine Kraftfahrzeugtüranordnung bekannt ( US 6,321,488 B1 ), bei der die Kraftfahrzeugtür im Rahmen eines Schließvorgangs mittels eines Türantriebs und einer Steuerung von einer Offenstellung in eine Schließstellung verstellbar ist. Im Sinne einer Sicherheitsfunktion bewirkt eine bestimmte Benutzerbetätigung während des motorischen Schließvorgangs der Kraftfahrzeugtür das sofortige Abschalten des Türantriebs und die Einstellung einer manuellen Betriebsart.Finally, a motor vehicle door assembly is known ( US 6,321,488 B1 ), in which the motor vehicle door in the context of a closing operation by means of a door drive and a controller from an open position to a closed position is adjustable. In the sense of a safety function causes a certain user operation during the motor closing of the vehicle door, the immediate shutdown of the door drive and the setting of a manual mode.

Neben dem hohen konstruktiven Aufwand ist bei dem bekannten motorischen Schließvorgang nachteilig, dass stets eine gewisse Einklemmgefahr besteht. Es lässt sich schlichtweg nicht vollständig ausschließen, dass sich der Benutzer mit einem B ein oder Arm im Einklemmbereich befindet.In addition to the high design effort is disadvantageous in the known motor closing that there is always a certain risk of trapping. It simply can not be completely ruled out that the user is with a B or an arm in Einklemmbereich.

Der Erfindung liegt das Problem zugrunde, das bekannte Verfahren zur motorischen Verstellung einer Kraftfahrzeugtür und die bekannte Kraftfahrzeugtüranordnung so auszugestalten und weiterzubilden, dass der Realisierungsaufwand bei hinreichendem Benutzungskomfort reduziert wird.The invention is based on the problem, the known method for the motorized adjustment of a motor vehicle door and the known motor vehicle door assembly in such a way and further develop that the implementation effort is reduced with sufficient ease of use.

Das obige Problem wird bei einem Verfahren gemäß dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above problem is solved in a method according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Wesentlich ist die Überlegung, den Schließvorgang für die Kraftfahrzeugtür teils motorisch und teils manuell vorzusehen. Dabei ist erkannt worden, dass es für die Bereitstellung eines erheblichen Benutzungskomforts ausreicht, die Kraftfahrzeugtür motorisch nur in einem ersten Abschnitt des Schließvorgangs zu verstellen. Der Türantrieb sorgt dabei für eine Verstellung der Kraftfahrzeugtür von der Offenstellung in eine sogenannte Komfortoffenstellung, die zwischen der Offenstellung und der Schließstellung liegt. Anschließend verstellt der Benutzer die Kraftfahrzeugtür in einem zweiten Abschnitt des Schließvorgangs manuell und weitgehend frei vom Türantrieb, Diese manuelle Verstellung ist eine Verstellung der Kraftfahrzeugtür von der Komfortoffenstellung in Richtung der Schließstellung.Essential is the consideration to provide the closing process for the motor vehicle door partly motor and partly manually. It has been recognized that it is sufficient for the provision of a considerable ease of use to adjust the motor vehicle door motor only in a first portion of the closing process. The door drive ensures an adjustment of the vehicle door from the open position into a so-called comfort open position, which lies between the open position and the closed position. Subsequently, the user adjusts the motor vehicle door in a second section of the closing operation manually and largely free of the door drive, this manual adjustment is an adjustment of the vehicle door from the comfort open position in the direction of the closed position.

Der Schließvorgang für die Kraftfahrzeugtür ist also in zwei Abschnitte unterteilt, von denen nur der erste Abschnitt eine motorische Verstellung der Kraftfahrzeugtür in obigem Sinne umfasst.The closing operation for the motor vehicle door is therefore subdivided into two sections, of which only the first section comprises a motorized adjustment of the motor vehicle door in the above sense.

Nach dem Einsteigen des Benutzers bringt der Türantrieb die Kraftfahrzeugtür in die Komfortoffenstellung, die so gelegen ist, dass der Türbetätigungsgriff vom Benutzer komfortabel erreichbar ist. Der weitere manuelle Teil des Schließvorgangs kann von dem Benutzer dann ohne große Mühe durchgeführt werden.After boarding the user, the door drive brings the vehicle door in the comfort of open position, which is located so that the door handle is easily accessible by the user. The further manual part of the closing operation can then be carried out by the user without great difficulty.

Wesentlich ist die Tatsache, dass der zweite Abschnitt des Schließvorgangs weitgehend frei vom Türantrieb erfolgen kann. Mit "weitgehend frei" ist gemeint, dass im zweiten Abschnitt des Schließvorgangs, also bei der manuellen Verstellung der Kraftfahrzeugtür, die Existenz des Türantriebs für den Benutzer nicht oder kaum spürbar ist. Dies ist dadurch realisiert, dass der Türantrieb im zweiten Abschnitt des Schließvorgangs von der Kraftfahrzeugtür antriebstechnisch getrennt ist.It is essential that the second section of the closing process can be largely free of the door drive. By "largely free" is meant that in the second section of the closing process, ie in the manual adjustment of the motor vehicle door, the existence of the door drive for the user is not or hardly noticeable. This is realized in that the door drive is separated in terms of drive technology from the motor vehicle door in the second section of the closing operation.

Ein weiterer interessanter Aspekt besteht ferner im Auslösen des Schließvorgangs durch bestimmte Benutzeraktionen, die nicht originär der Kraftfahrzeugtür zugeordnet sind, so dass das Auslösen des Schließvorgangs durch den Benutzer in der Regel unbewusst erfolgt. Beispielsweise kann es vorgesehen sein, dass der Schließvorgang durch die Belegung des der Kraftfahrzeugtür zugeordneten Fahrzeugsitzes erfolgt (Anspruch 6).Another interesting aspect is also in the triggering of the closing process by certain user actions that are not originally assigned to the motor vehicle door, so that the triggering of the closing process by the user is usually unconscious. For example, it may be provided that the closing operation is effected by the occupancy of the vehicle seat associated with the motor vehicle door (claim 6).

Nach einer weiteren Lehre, der ebenfalls eigenständige Bedeutung zukommt, wird eine Kraftfahrzeugtüranordnung gemäß Anspruch 10 beansprucht.According to another teaching, which also has independent significance, a motor vehicle door assembly according to claim 10 is claimed.

Auf die obigen Ausführungen zu dem vorschlagsgemäßen Verfahren darf in vollem Umfange verwiesen werden.Reference may be made in full to the above comments on the proposed method.

Eine bevorzugte Ausgestaltung besteht darin, dass sich die Übersetzungsverhältnisse zwischen dem Türantrieb und der Kraftfahrzeugtür beim Übergang vom ersten Abschnitt in den zweiten Abschnitt des Schließvorgangs so verändern, dass eine für den Benutzer spürbare Rückwirkung des Türantriebs auf die Kraftfahrzeugtür nicht vorhanden ist.A preferred embodiment is that change the ratios between the door drive and the vehicle door during the transition from the first section to the second section of the closing process so that a noticeable to the user feedback of the door drive is not present on the vehicle door.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. In der Zeichnung zeigt

Fig. 1 :
in einer Seitenansicht ein Kraftfahrzeug mit einer erfindungsgemäßen Kraftfahrzeugtüranordnung und
Fig. 2 :
das Kraftfahrzeug gemäß Fig. 1 in einer Schnittansicht entlang der Schnittlinie II-II bei in der Schließstellung (oben) und bei in der Offenstellung (unten) befindlicher Kraftfahrzeugtür.
In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows
Fig. 1:
in a side view of a motor vehicle with a motor vehicle door assembly according to the invention and
Fig. 2:
the motor vehicle according to Fig. 1 in a sectional view along the section line II-II in the closed position (above) and in the open position (below) befindlicher motor vehicle door.

Das in Fig. 1 dargestellte Kraftfahrzeug ist mit einer vorschlagsgemäßen Kraftfahrzeugtüranordnung ausgestattet, die vier Seitentüren 1, eine Motorraumklappe 2 und eine Kofferraumklappe 3 aufweist und die der Durchführung des vorschlagsgemäßen Verfahrens dient.This in Fig. 1 shown motor vehicle is equipped with a proposed motor vehicle door assembly having four side doors 1, an engine compartment door 2 and a trunk lid 3 and which serves to carry out the proposed method.

Je nach Ausgestaltung kann anstelle einer schwenkbaren Seitentür auch eine Schiebetür o.dgl. vorgesehen sein. Bei den Seitentüren 1, der Motorraumklappe 2, der Kofferraumklappe 3 und der ggf. vorhandenen Schiebetür o.dgl. handelt es sich jeweils um eine Kraftfahrzeugtür im vorliegenden Sinne. Im folgenden wird stellvertretend für alle genannten Arten von Kraftfahrzeugtüren ausschließlich die Seitentür 1 behandelt. Dies ist nicht beschränkend zu verstehen.Depending on the configuration, instead of a pivotable side door, a sliding door or the like. be provided. At the side doors 1, the engine compartment flap 2, the trunk lid 3 and the possibly existing sliding door or the like. each is a motor vehicle door in the present sense. In the following, only the side door 1 will be treated as representative of all mentioned types of motor vehicle doors. This is not meant to be limiting.

Die Kraftfahrzeugtür 1 ist im Rahmen eines Schließvorgangs von einer Offenstellung in eine Schließstellung verstellbar, wobei ein der Kraftfahrzeugtür 1 zugeordneter Türantrieb 4 und eine elektrische Steuerung 5 vorgesehen sind. Im Rahmen des Schließvorgangs ist die Kraftfahrzeugtür 1 mittels des Türantriebs 4 ausgehend von der Offenstellung in Schließrichtung verstellbar. Vorliegend geht es ausschließlich um den Schließvorgang für die Kraftfahrzeugtür 1. Der Öffnungsvorgang kann ungeachtet der speziellen Ausgestaltung des Schließvorgangs motorisch oder manuell realisiert sein.The motor vehicle door 1 is adjustable in the context of a closing operation from an open position to a closed position, wherein a door drive 4 assigned to the motor vehicle door 1 and an electric control 5 are provided. As part of the closing operation, the motor vehicle door 1 is adjustable by means of the door drive 4, starting from the open position in the closing direction. In the present case, it is all about the closing process for the motor vehicle door 1. The opening process, regardless of the specific embodiment of the closing operation, can be realized by a motor or manually.

Wesentlich ist nun, daß die Anordnung so getroffen ist, daß in einem ersten Abschnitt 6 des Schließvorgangs der Türantrieb 4 die Kraftfahrzeugtür 1 von der Offenstellung (in Fig. 2 unten) in eine Komfortoffenstellung (in Fig. 2 in gestrichelter Linie dargestellt), die zwischen der Offenstellung und der Schließstellung liegt, verstellt. Wesentlich ist ferner, daß in einem zweiten Abschnitt 7 des Schließvorgangs die Kraftfahrzeugtür manuell und weitgehend frei vom Türantrieb 4 ausgehend von der Komfortoffenstellung weiter in Schließrichtung, vorzugsweise in die Schließstellung, verstellbar ist. Grundsätzlich kann hier auch eine Schließhilfe vorgesehen sein, so daß die manuelle Verstellung nur bis zu einer Vorschließstellung notwendig ist. Dies wird weiter unten erläutert.It is essential that the arrangement is such that in a first section 6 of the closing operation of the door drive 4, the motor vehicle door 1 from the open position (in Fig. 2 below) in a comfort open position (in Fig. 2 shown in dashed line), which lies between the open position and the closed position, adjusted. It is also essential that in a second section 7 of the closing operation, the vehicle door is manually and largely free of the door drive 4, starting from the comfort open position further in the closing direction, preferably in the closed position, adjustable. In principle, a closing aid can also be provided here, so that manual adjustment is only necessary up to a prelocking position. This will be explained below.

Es wurde oben angesprochen, daß die Kraftfahrzeugtür 1 als Schwenktür (Fig. 1, 2) oder als Schiebetür ausgestaltet sein kann. Bei einer Schiebetür treten nämlich die gleichen oben genannten Probleme beim Schließvorgang auf, insbesondere wenn die Schiebetür der Fahrerseite zugeordnet ist.It has been mentioned above that the motor vehicle door 1 as swing door ( Fig. 1 . 2 ) or can be configured as a sliding door. In fact, in a sliding door, the same problems mentioned above occur during the closing process, especially when the sliding door is assigned to the driver's side.

Der geometrischen Ausdehnung des ersten Abschnitts 6 des Schließvorgangs einerseits und des zweiten Abschnitts 7 des Schließvorgangs andererseits kommt für den Benutzungskomfort und den Realisierungsaufwand besondere Bedeutung zu. Hierfür ist die Lage der Komfortoffenstellung maßgeblich.The geometric extension of the first portion 6 of the closing operation on the one hand and the second portion 7 of the closing operation on the other hand is of particular importance for the ease of use and the implementation effort. For this purpose, the position of comfort exposure is decisive.

Vorzugsweise ist die Komfortoffenstellung von der Schließstellung aus in Öffnungsrichtung gesehen in einem Bereich zwischen 25% und 85%, vorzugsweise zwischen. 30% und 70%, weiter vorzugsweise zwischen 35% und 55%, des Schwenkbereichs der Kraftfahrzeugtür gelegen.Preferably, the comfort open position is seen from the closed position in the opening direction in a range between 25% and 85%, preferably between. 30% and 70%, more preferably between 35% and 55%, of the swiveling range of the vehicle door.

Es wurde im allgemeinen Teil der Beschreibung erläutert, dass die Komfortoffenstellung letztlich so gelegen ist, dass der Türbetätigungsgriff vom Benutzer komfortabel erreichbar ist. Dies kann aber je nach Körpergröße des Benutzers erheblichen Schwankungen unterworfen sein. Entsprechend ist es erfindungsgemäß vorgesehen, dass die Lage der Komfortoffenstellung einstellbar ist. Denkbar ist hier eine mechanische Einstellbarkeit, beispielsweise durch das Verschieben eines Anschlags o. dgl. Denkbar ist aber auch eine elek-trische Einstellbarkeit, beispielsweise durch das Verändern der Ansteuerung einer ggf. vorgesehenen Kupplung o. dgl.It has been explained in the general part of the description that the comfort open position is ultimately located so that the door operating handle is easily accessible by the user. However, this can be subject to considerable fluctuations depending on the size of the user. Accordingly, it is provided according to the invention that the position of the comfort open position is adjustable. It is conceivable here is a mechanical adjustability, for example by moving a stopper o. The like. Also conceivable, however, is an elec tric adjustability, for example by changing the control of a possibly provided clutch o. The like.

Bei der in Fig. 2 dargestellten, erfindungsgemäß Ausgestaltung ist es vorgesehen, dass der Türantrieb 4 im zweiten Abschnitt 7 des Schließvorgangs von der Kraftfahrzeugtür 1 antriebstechnisch getrennt ist, so dass im zweiten Abschnitt 7 des Schließvorgangs die Kraftfahrzeugtür 1 manuell und weitgehend frei vom Türantrieb 4 verstellbar ist.At the in Fig. 2 illustrated, according to the invention embodiment, it is provided that the door drive 4 in the second section 7 of the closing operation of the motor vehicle door 1 is drivingly separated, so that in the second section 7 of the closing operation, the vehicle door 1 is manually and largely free of the door drive 4 adjustable.

Hier und vorzugsweise ist der Türantrieb 4 ein Ritzel-Zahnstangenantrieb. Der Türantrieb 4 weist einen in einem Hohlraum der Kraftfahrzeugtür 1 angeordneten Antriebsmotor 8 auf, der ein Ritzel 9 antreibt. Das Ritzel 9 kämmt mit einer Zahnstange 10, die an der Kraftfahrzeugkarosserie an einem Anlenkpunkt 11 angelenkt ist. Der Anlenkpunkt 11 ist derart beabstandet von der Schwenkachse 12 der Kraftfahrzeugtür, dass ein Antrieb des Ritzels 9 über die Zahnstange 10 im Ergebnis zu einem Verschwenken der Kraftfahrzeugtür 1 führt.Here and preferably, the door drive 4 is a pinion rack drive. The door drive 4 has a arranged in a cavity of the motor vehicle door 1 drive motor 8, which drives a pinion 9. The pinion 9 meshes with a rack 10 which is hinged to the vehicle body at a pivot point 11. The articulation point 11 is so spaced from the pivot axis 12 of the motor vehicle door, that a drive of the pinion 9 via the rack 10 as a result leads to a pivoting of the motor vehicle door 1.

Wesentlich ist nun die Tatsache, dass ein Element 9 des Türantriebs 4, hier das Ritzel 9, durch die Verstellung der Kraftfahrzeugtür 1 in Schließrichtung über die Komfortoffenstellung hinaus außer antriebstechnischen Eingriff von einem Element 10 der Kraftfahrzeugtür 1, hier der Zahnstange 10, kommt und dadurch die antriebstechnische Trennung des Türantriebs 4 von der Kraftfahrzeugtür 1 erfolgt. Hierfür weist die Zahnstange 10 einen Abschnitt 10a mit einem Freischnitt ohne Zahnstangenverzahnung und einen Abschnitt 10b mit der üblichen Zahnstangenverzahnung auf.What is essential now is the fact that an element 9 of the door drive 4, here the pinion 9, by the adjustment of the motor vehicle door 1 in the closing direction beyond the comfort open position except driving engagement of an element 10 of the vehicle door 1, here the rack 10, and thereby the drive technology separation of the door drive 4 of the motor vehicle door 1 takes place. For this purpose, the rack 10 has a section 10 a with a cutout without rack teeth and a section 10b with the usual rack teeth on.

Im ersten Abschnitt 6 des Schließvorgangs steht das Ritzel 9 in antriebstechnischem Eingriff mit der Zahnstange 10, insbesondere mit dem Abschnitt 10b, so daß mittels des Türantriebs 4 eine Verstellung der Kraftfahrzeugtür 1 von der Offenstellung in die Komfortoffenstellung möglich ist.In the first section 6 of the closing operation, the pinion 9 is in driving engagement with the rack 10, in particular with the portion 10b, so that by means of the door drive 4, an adjustment of the motor vehicle door 1 from the open position to the comfort position is possible.

In der Komfortoffenstellung, die in Fig. 2 in gestrichelter Linie dargestellt ist, kommt das Ritzel 9 außer antriebstechnischen Eingriff von der Verzahnung des Abschnitts 10b der Zahnstange 10, so daß die Zahnstange 10 bei weiterer Verstellung in Schließrichtung frei vom Ritzel 9 bewegbar ist. Das Ritzel 9 durchläuft dann den den Freischnitt aufweisenden Abschnitt 10a. Damit ist insgesamt die Kraftfahrzeugtür 1 weitgehend frei vom Türantrieb 4 verstellbar, wenn man das nicht ins Gewicht fallende Mitführen der Zahnstange 10 vernachlässigt.In the comfort open position, which in Fig. 2 is shown in dashed line, the pinion 9 comes except drive input from the teeth of the portion 10b of the rack 10, so that the rack 10 is movable in further adjustment in the closing direction of the pinion 9 free. The pinion 9 then passes through the cut-free portion 10 a. Thus, a total of the motor vehicle door 1 is largely freely adjustable by the door drive 4, if one neglects the not significant falling entrainment of the rack 10.

Die in Fig. 2 dargestellte und insoweit bevorzugte Ausgestaltung ist einfach und robust aufgebaut. Grundsätzlich kann es aber auch vorgesehen sein, daß zwischen dem Türantrieb 4 und der Kraftfahrzeugtür 1 eine Kupplung angeordnet ist und daß mittels der Kupplung die antriebstechnische Trennung in der Komfortoffenstellung erzeugbar ist. Dabei ist die Kupplung vorzugsweise als elektrisch schaltbare Kupplung ausgestaltet.In the Fig. 2 illustrated and so far preferred embodiment is simple and robust. In principle, however, it can also be provided that between the door drive 4 and the motor vehicle door 1, a clutch is arranged and that by means of the clutch, the drive-related separation in the comfort open position can be generated. In this case, the coupling is preferably designed as an electrically switchable coupling.

Bei einer weiteren bevorzugten Ausgestaltung kann auf mechanische Übergänge oder Kupplungen vollständig verzichtet werden. Hier ist es so, daß der Türantrieb 4 eine Koppelmechanik zur Übertragung der Antriebskraft zwischen der Kraftfahrzeugtür 1 und der Kraftfahrzeugkarosserie aufweist und daß sich mit der Verstellung der Kraftfahrzeugtür 1 in Schließrichtung über die Komfortoffenstellung hinaus die Übersetzung der Koppelmechanik so verändert, daß im zweiten Abschnitt 7 des Schließvorgangs die Kraftfahrzeugtür 1 manuell und weitgehend frei vom Türantrieb 4 verstellbar ist. Ein Beispiel für eine solche Koppelmechanik wäre beispielsweise eine Viergelenkmechanik, sofern diese in geeigneter Weise ausgelegt ist.In a further preferred embodiment can be completely dispensed with mechanical transitions or couplings. Here, it is so that the door drive 4 has a coupling mechanism for transmitting the driving force between the motor vehicle door 1 and the vehicle body and that with the adjustment of the motor vehicle door 1 in the closing direction beyond the comfort open position, the translation of the coupling mechanism changed so that in the second section. 7 the closing operation, the vehicle door 1 is manually and largely free of the door drive 4 adjustable. An example of such a coupling mechanism would be, for example, a four-bar mechanism, if this is designed in a suitable manner.

Eine besonders kompakte Ausgestaltung ergibt sich dadurch, daß der Türantrieb 4 mit anderen Komponenten der Kraftfahrzeugtür 1 kombiniert wird. In besonders bevorzugter Ausgestaltung ist es vorgesehen, daß der Türantrieb 4 Bestandteil eines Türfeststellers ist. Dies läßt sich bei der in Fig. 2 dargestellten Ausgestaltung einfach dadurch realisieren, daß das Ritzel 8 beispielsweise bei in der Offenstellung befindlicher Kraftfahrzeugtür 1 gebremst wird.A particularly compact design results from the fact that the door drive 4 is combined with other components of the motor vehicle door 1. Especially preferred embodiment, it is provided that the door drive 4 is part of a door arrester. This can be found in the in Fig. 2 illustrated embodiment simply by the fact that the pinion 8 is braked for example in befindlichem in the open position motor vehicle door 1.

Der optimalen Ansteuerung des Türantriebs 4 kommt vorliegend besondere Bedeutung zu. Insbesondere ist dafür zu sorgen, daß beim Übergang vom ersten Abschnitt 6 in den zweiten Abschnitt 7 des Schließvorgangs ein Abschalten des Türantriebs 4 und ggf. ein Schalten der Kupplung erfolgt. Diese Vorgänge werden vorzugsweise von der Steuerung 5 bewirkt. Grundsätzlich ist es auch denkbar, daß die Steuerung 5 vorbestimmte Geschwindigkeitsverläufe bei der motorischen Verstellung der Kraftfahrzeugtür 1 umsetzt.The optimal control of the door drive 4 is of particular importance in the present case. In particular, it must be ensured that, during the transition from the first section 6 into the second section 7 of the closing operation, the door drive 4 is switched off and, if necessary, the clutch is switched. These operations are preferably effected by the controller 5. In principle, it is also conceivable that the controller 5 converts predetermined speed profiles in the motorized adjustment of the motor vehicle door 1.

Im Hinblick auf den erreichbaren Benutzungskomfort kommt dem Auslösen des Schließvorgangs besondere Bedeutung zu. Bei einer einfachen Ausgestaltung ist es so, daß für das Auslösen des Schließvorgangs ein mit der Steuerung 5 gekoppeltes Betätigungselement 13 im Fahrzeuginnenraum vorgesehen ist.With regard to the achievable ease of use, the triggering of the closing process is of particular importance. In a simple embodiment, it is so that is provided for triggering the closing operation coupled to the controller 5 actuator 13 in the vehicle interior.

Grundsätzlich ist es aber auch denkbar, daß das Auslösen des Schließvorgangs durch den Benutzer unbewußt erfolgt. Dabei ist es zunächst vorgesehen, daß die Steuerung 5 einen Teil der Benutzeraktionen im Fahrzeuginnenraum erfaßt und bei Vorliegen einer vorbestimmten Benutzeraktion bzw. einer vorbestimmten Kombination von Benutzeraktionen den Schließvorgang auslöst. Dabei ist es in besonders bevorzugter Ausgestaltung ferner vorgesehen, daß diese den Schließvorgang auslösenden Benutzeraktionen nicht originär der Kraftfahrzeugtür 1 zugeordnet sind, so daß das Auslösen des Schließvorgangs durch den Benutzer in der Regel unbewußt erfolgt. Vorteilhafterweise läuft bzw. laufen die den Schließvorgang auslösende Benutzeraktion bzw. die den Schließvorgang auslösenden Benutzeraktionen dann ohne die aktive Handhabung eines elektronischen Bedienteils o. dgl., insbesondere Fernbedienteils o. dgl., ab.Basically, it is also conceivable that the triggering of the closing process by the user is unconscious. It is initially provided that the controller 5 detects part of the user actions in the vehicle interior and triggers the closing process in the presence of a predetermined user action or a predetermined combination of user actions. It is also provided in a particularly preferred embodiment, further, that these closing actions are not originally associated with the vehicle door 1, so that the triggering of the closing process by the user is usually unconscious. Advantageously, the user action triggering the closing operation or the user actions initiating the closing operation then run or run without the active handling of an electronic control unit or the like, in particular a remote control unit or the like.

Beispielsweise ist es vorzugsweise vorgesehen, daß die Steuerung 5 mittels einer Sensoranordnung die Belegung eines Fahrzeugsitzes, vorzugsweise des der Kraftfahrzeugtür zugeordneten Fahrzeugsitzes, erfaßt und daß die Erfassung dieser Benutzeraktion notwendig, vorzugsweise hinreichend, für das Auslösen des Schließvorgangs für die Kraftfahrzeugtür ist. Mit "notwendig" ist gemeint, daß ggf. eine weitere Benutzeraktion von der Steuerung 5 erfaßt werden muß, um das Auslösen des Schließvorgangs zu bewirken. Mit "hinreichend" ist gemeint, daß diese Erfassung der Benutzeraktion ausreicht, um den Schließvorgang auszulösen. Basierend auf diesen notwendigen oder hinreichenden Bedingungen wird in der Steuerung 5 in Abhängigkeit von der jeweiligen sensorischen Erfassung ein Entscheidung darüber getroffen, ob der Schließvorgang ausgelöst wird oder nicht.For example, it is preferably provided that the controller 5 detects the occupancy of a vehicle seat, preferably of the vehicle door associated vehicle seat, and that the detection of this user action is necessary, preferably sufficient, for triggering the closing process for the vehicle door by means of a sensor arrangement. By "necessary" is meant that If necessary, another user action must be detected by the controller 5 to cause the triggering of the closing operation. By "sufficient" is meant that this detection of the user action is sufficient to trigger the closing process. Based on these necessary or sufficient conditions, a decision is made in the controller 5 depending on the respective sensory detection, whether the closing process is triggered or not.

In bevorzugter Ausgestaltung ist es vorgesehen, daß die Steuerung 5 mittels einer Sensoranordnung den Zugang eines Benutzers in den Fahrzeuginnenraum erfaßt und daß die Erfassung dieser Benutzeraktion notwendig, vorzugsweise hinreichend, für das Auslösen des Schließvorgangs ist.In a preferred embodiment, it is provided that the controller 5 detects the access of a user in the vehicle interior by means of a sensor arrangement and that the detection of this user action is necessary, preferably sufficient, for triggering the closing operation.

In der Regel wird es nicht ausreichen, den Zugang eines Benutzers in den Fahrzeuginnenraum zu erfassen, um den Schließvorgang auszulösen. In vielen Fällen wird der Benutzer nämlich noch nicht vollständig im Fahrzeuginnenraum untergebracht sein, so daß grundsätzlich die Gefahr des Einklemmens besteht. Daher müssen vorzugsweise zusätzliche Benutzeraktionen wie beispielsweise die oben beschriebene Belegung eines Fahrzeugsitzes ablaufen, um den Schließvorgang auslösen zu können.In general, it will not be sufficient to detect the access of a user in the vehicle interior to trigger the closing process. In many cases, the user will not be completely housed in the vehicle interior, so that in principle there is a risk of trapping. Therefore, additional user actions, such as the occupancy of a vehicle seat described above, preferably have to take place in order to be able to trigger the closing process.

Besonders vorteilhaft ist es, wenn die Steuerung 5 mittels einer Sensoranordnung das Schließen eines Sicherheitsgurts erfaßt und daß die Erfassung dieser Benutzeraktion wieder notwendig, vorzugsweise hinreichend, für das Auslösen des Schließvorgangs ist.It is particularly advantageous if the controller 5 detects the closing of a safety belt by means of a sensor arrangement and that the detection of this user action is again necessary, preferably sufficient, for the triggering of the closing operation.

Bei einer weiter bevorzugten Ausgestaltung ist ein Lenkradschloß vorgesehen, wobei die Steuerung 5 mittels einer Sensoranordnung das Entriegeln des Lenkradschlosses erfaßt und daß die Erfassung dieser Benutzeraktion notwendig, vorzugsweise hinreichend, für das Auslösen des Schließvorgangs ist.In a further preferred embodiment, a steering lock is provided, wherein the controller 5 detects the unlocking of the steering lock by means of a sensor arrangement and that the detection of this user action is necessary, preferably sufficient, for triggering the closing operation.

Bei Fahrzeugen neueren Datums wird zunehmend ein elektrischer Motorstartknopf für das Starten des Motors des Kraftfahrzeugs vorgesehen, wobei die Steuerung 5 die Betätigung des Motorstartknopfes erfaßt und wobei die Erfassung dieser Benutzeraktion notwendig, vorzugsweise hinreichend, für das Auslösen des Schließvorgangs ist.In more recent vehicles, an electric engine start button for starting the engine of the motor vehicle is increasingly provided, wherein the controller 5 detects the operation of the engine start button and wherein the detection of this user action is necessary, preferably sufficient, for the triggering of the closing operation.

Üblicherweise ist in einem Kraftfahrzeug auch ein Handbremshebel vorgesehen.
