Description
Die Erfindung betrifft ein Verfahren zum automatischen Betätigen einer Kraftfahrzeugtür, insbesondere der Heckklappe eines Kraftfahrzeuges, von einer ersten in eine zweite Endstellung mittels eines Antriebes, der eine durch eine Steuereinrichtung betätigbare elektromagnetische Reib-Kupplung mit einer bestrombaren Spule umfaßt.The The invention relates to a method for automatically actuating a Motor vehicle door, in particular the tailgate of a motor vehicle, from a first in a second end position by means of a drive, a through a control device operable Includes electromagnetic friction clutch with a current supplied coil.
Als Fahrzeugtür im Sinne dieser Erfindung wird zusammenfassend jedes verschwenkbare Teil eines Fahrzeuges zum Verschließen einer Öffnung bezeichnet. Es kann sich bei der Fahrzeugtür daher sowohl um eine Seiten- oder Hecktür als auch um eine Heckklappe (Kofferraumdeckel), eine Motorhaube, eine Dachklappe oder dgl. handeln.When vehicle door For the purposes of this invention, in summary, any pivotable Part of a vehicle for closing an opening. It can at the vehicle door therefore both a side or tailgate and a tailgate (Trunk lid), a hood, a roof flap or the like. Act.
Bei automatisch betätigbaren Heckklappen von Kraftfahrzeugen wird die Heckklappe zum Öffnen und Schließen zum Teil mit voller Leistung des Antriebes in ihre durch Endanschläge definierte Endstellungen geschwenkt und der Antrieb erst dann abgeschaltet.at automatically actuated Tailgates of motor vehicles will open the tailgate and Shut down partly with full power of the drive in their final stops defined Pivoting end positions and the drive is then switched off.
Als nachteilig hat es sich hierbei erwiesen, daß die Antriebseinheiten relativ stark beansprucht werden, weil immer dieselben Verzahnungsbereiche des Antriebes die relativ hohen Anschlagskräfte abbauen müssen. Diese sogenannte Blockzahnbildung reduziert die Lebensdauer eines solchen Antriebes und macht zum Teil die Verwendung anderer Materialien notwendig. Außerdem werden durch den harten Endanschlag die Heckklappenscharniere außerordentlich stark beansprucht und Anschlagsgeräusche verursacht.When disadvantageous it has proven here that the drive units relative be stressed because always the same gearing areas of the Drive must reduce the relatively high impact forces. These So-called block tooth formation reduces the life of such Drive and makes the use of other materials in part necessary. Furthermore Be made by the hard end stop the tailgate hinges extraordinarily heavily used and causes stop noises.
Es ist daher bereits vorgeschlagen worden, bei automatisch betätigbaren Heckklappen von Kraftfahrzeugen die Heckklappe nicht vollständig mittels des entsprechenden Antriebes zu öffnen, sondern die Kupplung des Antriebes kurz (d.h. z.B. 3 bis 15°) vor Erreichen des oberen Endanschlages auszukuppeln und die Heckklappe anschließend mit Hilfe einer Gasfeder bis zum Erreichen der Endstellung zu verschwenken.It has therefore already been proposed, with automatically operable Tailgates of motor vehicles, the tailgate is not completely by means of corresponding drive to open, but the clutch of the drive short (i.e., for example, 3 to 15 °) before reaching Disconnect the upper end stop and then the tailgate with Help a gas spring to reach the end position to pivot.
Als nachteilig hat es sich bei diesem Verfahren allerdings erwiesen, daß insbesondere bei extremer Kälte die dadurch reduzierten Rückstellkräfte der Gasfedern und eventuell auftretende Ablagerungen auf der Heckscheibe (z.B. Schnee) dazu führen, daß die Heckklappe nach Auskuppeln der Kupplung in ihre geschlossene Lage zurückfällt, was unter anderem zu Verletzungen von Personen führen kann, die sich im Heckklappenbereich aufhalten.When However, it has proved disadvantageous in this method that in particular in extreme cold the resulting reduced restoring forces of the gas springs and any deposits on the rear window (e.g. Snow) cause that the Tailgate after disengaging the clutch in its closed position fall back, what Among other things, it can lead to personal injury in the tailgate area stop them.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dessen Hilfe die automatisch betätigbare Fahrzeugtür eines Kraftfahrzeuges auch bei extremen Temperaturen unterhalb 0°C sicher in die jeweils gewünschte Endstellung geschwenkt wird, ohne daß es zu einer übermäßigen Belastung der Antriebseinheiten und der Türscharniere kommt.Of the Invention has for its object to provide a method with its help the automatically operable vehicle door a motor vehicle even at extreme temperatures below 0 ° C safely in the respectively desired End position is pivoted, without causing excessive stress the drive units and the door hinges comes.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.
Die Erfindung beruht im wesentlichen auf dem Gedanken, den zur Betätigung der Reib-Kupplung durch die Spule fließenden Erregerstrom zu vermindern, sobald die Fahrzeugtür eine vorgegebene, vor der jeweiligen Endstellung der Fahrzeugtür liegende Schaltstellung erreicht, so daß die Fahrzeugtür anschließend von dem Antrieb mit einem von der Reib-Kupplung übertragenen verminderten Drehmoment in ihre Endstellung bewegt wird.The The invention is based essentially on the idea that for the operation of the Friction clutch through the coil is flowing To reduce excitation current as soon as the vehicle door is a predetermined, before the reaches the respective end position of the vehicle door lying shift position, So that the vehicle door subsequently from the drive with a reduced torque transmitted by the friction clutch is moved to its end position.
Bei einer Ausführungsform der Erfindung wird der zeitliche Verlauf des Erregerstromes durch die Spule derart gewählt, daß das von der Reib-Kupplung übertragene Drehmoment kontinuierlich von einem Maximalwert bis zu einem vorgegebenen Endwert allmählich reduziert wird. Dieses kann beispielsweise durch einen definiert vorgegebenen rampenförmigen Verlauf des Erregerstromes erfolgen.at an embodiment the invention, the time course of the excitation current through the Coil chosen such that this transmitted from the friction clutch Torque continuously from a maximum value to a predetermined one Final value gradually is reduced. This can for example be defined by one given ramp-shaped Course of the excitation current done.
Bei einer weiteren Ausführungsform der Erfindung wird als steuerbare elektromagnetische Reib-Kupplung eine Kupplung verwendet, die ein zusätzliches elastisches Element oder einen Permanentmagneten umfaßt, welches(r) bewirkt, daß die Reib-Kupplung auch in dem nicht bestromten Zustand der Spule ein vermindertes Drehmoment überträgt, das derart gewählt wird, daß die Fahrzeugtür nach Abschalten des Antriebes in der jeweiligen Position zwar stehen bleibt, aber eine manuelle Betätigung der Fahrzeugtür möglich ist.at a further embodiment The invention is a controllable electromagnetic friction clutch a clutch is used, which is an additional elastic element or a permanent magnet, which (r) causes the friction clutch also in the non-energized state of the coil a reduced Torque transmits that chosen like that will that the Vehicle door after Switch off the drive in the respective position while standing remains, but a manual operation the vehicle door possible is.
Bei
Verwendung derartiger, beispielsweise aus der
Es versteht sich von selbst, daß bei Fahrzeugtüren, deren Öffnungs- oder Schließbewegung durch mindestens ein elastisches Element (z.B. eine Gasfeder) unterstützt wird, der durch die Spule der Reib-Kupplung fließende Erregerstrom nach Erreichen der Schaltstellung so weit vermindert werden kann, daß die Fahrzeugtür von der Rückstellkraft des elastischen Elementes und dem Antrieb zusammen in die jeweilige Endstellung bewegt wird.It goes without saying that in the case of vehicle doors, their opening or closing movement is supported by at least one elastic element (eg a gas spring), the exciting current flowing through the coil of the friction clutch can be reduced so far after reaching the switching position that the vehicle door of the restoring force of the elastic element and the drive together in the respective end position is moved.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:Further Details and advantages of the invention will become apparent from the following explained with reference to figures Embodiments. Show it:

Die Erfindung ist keineswegs auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann es vorteilhaft sein, den Erregerstrom der Spule der Reib-Kupplung bei Erreichen der Schaltstellung nicht vollständig abzuschalten, sondern nur allmählich zu reduzieren, um zu vermeiden, daß durch eine plötzliche Verminderung des zu übertragenden Drehmomentes ruckartige Bewegungen der Antriebsteile bzw. der Heckklappe verursacht werden.The Invention is by no means to the embodiment described above limited. So It may be advantageous, the excitation current of the coil of the friction clutch not completely switch off when reaching the switch position, but only gradually to reduce, by a sudden Reduction of the to be transferred Torque jerky movements of the drive parts or the tailgate caused.
Bei dem Lagesensor braucht es sich nicht zwingend um einen von dem Antrieb separaten Sensor handeln. Vielmehr kann der Lagesensor auch in den Antrieb integriert werden und z.B. zur Lagebestimmung der Heckklappe statt deren Schwenkwinkel die Umdrehung der Abtriebswelle auswerten.The position sensor does not necessarily have to be a separate sensor from the drive. Rather, the position sensor can also be integrated into the drive and eg for Lagebe mood of the tailgate instead of the swivel angle evaluate the rotation of the output shaft.
Außerdem muß der Antrieb nicht zwingend mit der Scharnierachse der Heckklappe verbunden sein, sondern er kann beispielsweise auch auf einen mit der Heckklappe verbundenen Scharnierbügel wirken.In addition, the drive must not necessarily connected to the hinge axis of the tailgate, but he can, for example, on one with the tailgate connected hinge hanger Act.
