Description

Cabrioletanordnung mit Einklemmschutzeinrichtung Cabriolet arrangement with anti-trap device
Die Erfindung betrifft eine Cabrioletanordnung, umfassend die Merkmale des Oberbegriffs des Patentanspruchs 1. The invention relates to a convertible arrangement, comprising the features of the preamble of patent claim 1.
Eine derartige Cabrioletanordnung ist beispielsweise aus der Druckschrift Such a convertible arrangement is, for example, from the publication
DE 102 48 761 B4 bekannt und umfasst ein Verdeck mit einem Verdeckgestänge und einem Verdeckbezug, der mittels des Verdeckgestänges zwischen einer einen Fahrzeuginnenraum überspannenden Verdeckstellung und einer den Fahrzeuginnenraum nach oben freigebenden Ablagestellung verstellbar ist. Der Verdeckbezug ist faltbar ausgebildet und ist in der Verdeckstellung mittels des Verdeckgestänges aufgespannt. In der Ablagestellung ist der Verdeckbezug in gefalteter Weise in einem Verdeckablageraum angeordnet. Um zu verhindern, dass Personen bei einem Verstellen des Verdecks eingeklemmt werden, weist das Verdeck eine Einklemmschutzeinrichtung auf, die einen kapazitiven Sensor umfasst. Der kapazitive Sensor umfasst eine Sensorfolie, welche an Gestängeteilen des Verdeckgestänges angebracht ist. Beim Verstellen des Verdecks ändert sich die Kapazität, die mittels des kapazitiven Sensors ermittelbar ist. Die Änderung der Kapazität folgt einer Kennlinie. Wenn ein Nutzer oder ein Gegenstand in die Bewegungsbahn des Verdecks gelangt, ändert sich ebenfalls die mittels des kapazitiven Sensors ermittelte Kapazität. Diese Änderung weicht aber von den Sollwerten ab, wodurch eine Einklemmsituation detektiert wird und ein Antrieb des Verdecks gestoppt oder reversiert werden kann. DE 102 48 761 B4 is known and comprises a top with a top linkage and a top cover, which can be adjusted by means of the top linkage between a top position spanning a vehicle interior and a storage position releasing the vehicle interior upwards. The top cover is designed to be foldable and is stretched open in the top position by means of the top linkage. In the storage position, the top cloth is arranged in a folded manner in a top storage space. In order to prevent people from being trapped when the convertible top is adjusted, the convertible top has an anti-trap device that includes a capacitive sensor. The capacitive sensor includes a sensor film which is attached to linkage parts of the top linkage. When the top is adjusted, the capacitance that can be determined using the capacitive sensor changes. The change in capacitance follows a characteristic. If a user or an object enters the path of movement of the convertible top, the capacitance determined by the capacitive sensor also changes. However, this change deviates from the setpoint values, as a result of which a pinching situation is detected and a drive of the convertible top can be stopped or reversed.
Der Erfindung liegt die Aufgabe zugrunde, eine gemäß der einleitend genannten Art ausgebildete Cabrioletanordnung mit einer optimierten Einklemmschutzeinrichtung auszustatten. Diese Aufgabe ist erfindungsgemäß durch die Cabrioletanordnung mit den Merkmalen des Patentanspruchs 1 gelöst. The object of the invention is to equip a convertible arrangement designed according to the type mentioned in the introduction with an optimized anti-trap device. According to the invention, this object is achieved by the convertible arrangement having the features of patent claim 1 .
Gemäß der Erfindung wird also eine Cabrioletanordnung vorgeschlagen, die ein Verdeck mit einem Verdeckgestänge und einem Verdeckbezug umfasst, der mittels des Verdeckgestänges zwischen einer einen Fahrzeuginnenraum überspannenden Verdeckstellung und einer den Fahrzeuginnenraum nach oben freigebenden Ablagestellung verstellbar ist. Eine Einklemmschutzvorrichtung umfasst einen kapazitiven Sensor, der mindestens zwei Elektroden umfasst, die als Schichten ausgebildet sind, die Bestandteil eines Schichtaufbaus des Verdeckbezugs sind. Der kapazitive Sensor der Einklemmschutzeinrichtung ist also in direkter Weise in einen Schichtaufbau des Verdeckbezugs integriert, und zwar dadurch, dass leitfähige Schichten ausgebildet sind, die durch ein Dielektrikum getrennt sind und die die Elektroden des kapazitiven Sensors bzw. Kondensators bilden, dessen Kapazität sich dadurch signifikant ändert, dass eine Person o- der ein Gegenstand sich dem Verdeckbezug annähert oder diesen berührt. Ein solches Ereignis wird als Risikoereignis angesehen, so dass durch entsprechende Mittel ein Antrieb des Verdecks angesteuert und gestoppt oder reversiert werden kann. Damit ist eine wirksame Einklemmschutzeinrichtung bereitgestellt. According to the invention, a cabriolet arrangement is proposed which includes a top with a top linkage and a top cover which can be adjusted by means of the top linkage between a top position spanning a vehicle interior and a storage position releasing the vehicle interior upwards. An anti-trap device includes a capacitive sensor that includes at least two electrodes that are formed as layers that are part of a layered structure of the top cover. The capacitive sensor of the anti-trap device is therefore directly integrated into a layered structure of the top cloth, specifically in that conductive layers are formed, which are separated by a dielectric and which form the electrodes of the capacitive sensor or capacitor, the capacitance of which increases significantly as a result changes that a person or an object approaches or touches the top fabric. Such an event is regarded as a risk event, so that a drive of the convertible top can be controlled and stopped or reversed by appropriate means. An effective anti-trap device is thus provided.
Die Elektroden des kapazitiven Sensors sind vorzugsweise großflächig oder vollflächig an dem Verdeckbezug ausgebildet, so dass der Verdeckbezug nahezu über seine gesamte Fläche als kapazitiver Sensor wirkt. Eine elektrische Isolierung des Verdeckbezugs gegenüber dem Verdeckgestänge ist zweckmäßigerweise realisiert. The electrodes of the capacitive sensor are preferably formed over a large area or over the entire surface of the top cloth, so that the top cloth acts as a capacitive sensor over almost its entire surface. Electrical insulation of the top cover from the top linkage is expediently implemented.
Zwischen den Elektroden des kapazitiven Sensors ist ein Dielektrikum in Form eines elektrisch isolierenden Materials angeordnet. Beispielsweise ist das Dielektrikum von einer folienartigen Kunststoffschicht oder dergleichen gebildet. A dielectric in the form of an electrically insulating material is arranged between the electrodes of the capacitive sensor. For example, the dielectric is formed by a film-like plastic layer or the like.
Um den Verdeckantrieb in Abhängigkeit von dem Messergebnis des kapazitiven Sensors ansteuem zu können, sind die Elektroden des kapazitiven Sensors vorzugsweise mit einer Mess- und Steuerelektronik verbunden, die in Abhängigkeit von einem Messsignal des kapazitiven Sensors einen Verdeckantrieb ansteuert. Die Mess- und Steuerelektronik kann einen üblichen Schaltkreis zur Messung von Kapazitäten umfassen. Die großflächig an dem Verdeckbezug ausgebildeten Elektrodenschichten können in vielfältiger Weise ausgebildet sein. Beispielsweise ist eine der Elektroden aus einer elektrisch leitfähigen Lackschicht gebildet, welche nach einem Sprühverfahren oder einem sonstigen geeigneten Auftragverfahren auf eine Trägerschicht des Verdeckbezugs aufgebracht ist. In order to be able to control the convertible top drive as a function of the measurement result of the capacitive sensor, the electrodes of the capacitive sensor are preferably connected to measurement and control electronics, which control a convertible top drive as a function of a measurement signal from the capacitive sensor. The measurement and control electronics can include a conventional circuit for measuring capacitances. The electrode layers formed over a large area on the top cloth can be formed in a variety of ways. For example, one of the electrodes is formed from an electrically conductive paint layer which is applied to a carrier layer of the top cover using a spraying process or some other suitable application process.
Denkbar ist es auch, dass zumindest eine der Elektroden aus einer elektrisch leitenden Folienanordnung gebildet ist. It is also conceivable that at least one of the electrodes is formed from an electrically conductive film arrangement.
Um eine hohe mechanische Belastbarkeit der Elektroden hinsichtlich Dehnbarkeit und Flexibilität zu realisieren, umfassen die Elektroden bei einer bevorzugten Ausführungsform der Cabrioletanordnung nach der Erfindung Graphen als Werkstoff, d. h. eine Modifikation des Kohlenstoffs mit einer zweidimensionalen elektrisch leitfähigen Struktur. In order to achieve a high mechanical load capacity of the electrodes in terms of extensibility and flexibility, the electrodes in a preferred embodiment of the convertible arrangement according to the invention comprise graphene as the material, i. H. a modification of carbon with a two-dimensional electrically conductive structure.
Bei einer weiteren speziellen Ausführungsform der Cabrioletanordnung nach der Erfindung umfasst der Schichtaufbau eine leitfähige Gummischicht, welche eine der Elektroden des kapazitiven Sensors bildet. Die leitfähige Gummischicht kann nach Art einer Gummischicht ausgebildet sein, die wie bei einem herkömmlichen Verdeckbezug zwischen zwei Textilschichten angeordnet ist. In a further special embodiment of the convertible arrangement according to the invention, the layer structure comprises a conductive rubber layer which forms one of the electrodes of the capacitive sensor. The conductive rubber layer can be designed in the manner of a rubber layer, which is arranged between two textile layers as in a conventional top cover.
Denkbar ist es auch, an dem Verdeckbezug zumindest eine leitfähige Textilschicht auszubilden, welche eine Elektrode des kapazitiven Sensors bildet. Diese leitfähige Textilschicht muss von der zweiten Elektrode des kapazitiven Sensors elektrisch isoliert sein, beispielsweise durch eine Gummischicht, eine Kunststofffolie oder dergleichen. It is also conceivable to form at least one conductive textile layer on the top cloth, which forms an electrode of the capacitive sensor. This conductive textile layer must be electrically isolated from the second electrode of the capacitive sensor, for example by a rubber layer, a plastic film or the like.
In der Regel umfasst ein Verdeckbezug eines Faltverdecks eine faltbare Außenhaut und einen faltbaren Innenhimmel. Der Schichtaufbau mit den Elektroden des kapazitiven Sensors kann an dem faltbaren Innenhimmel und/oder der Außenhaut ausgebildet sein, ohne dass sich im Vergleich zu bisherigen Verdeckbezügen das optische Erscheinungsbild ändert. As a rule, a top cover of a folding top comprises a foldable outer skin and a foldable inner liner. The layer structure with the electrodes of the capacitive sensor can be formed on the foldable roof liner and/or the outer skin without the optical appearance changing in comparison to previous top covers.
Die Erfindung hat auch ein Cabrioletfahrzeug zum Gegenstand, das eine Cabrioletanordnung der vorstehend beschriebenen Art umfasst. Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Patentansprüchen entnehmbar. The subject matter of the invention is also a convertible vehicle which comprises a convertible arrangement of the type described above.

In Figur 1 ist ein Cabrioletfahrzeug 10 dargestellt, welches mit einem als Faltverdeck ausgebildeten Verdeck 12 ausgestattet ist, welches zwischen einer in Figur 1 dargestellten, einen Fahrzeuginnenraum 14 überspannenden Schließstellung und einer nicht näher dargestellten Öffnungsstellung verstellbar ist, in der es von einem heckseitigen Verdeckablageraum 16 aufgenommen ist. Das Verdeck 12 umfasst ein Verdeckgestänge 18, welches bezogen auf eine vertikale Verdecklängsmittelebene beidseits jeweils eine Lenkeranordnung 20 umfasst, die an einem jeweiligen fahrzeugfesten Hauptlager 22 schwenkbar gelagert ist. Zum Antrieb ist an den Hauptlagern 22 jeweils ein Antriebsmotor 24 angeordnet, welcher als Elektromotor ausgebildet sein kann und auf einen Hauptlenker der betreffenden Lenkeranordnung wirkt. Figure 1 shows a convertible vehicle 10, which is equipped with a folding top 12, which can be adjusted between a closed position, shown in Figure 1, spanning a vehicle interior 14, and an open position, not shown, in which it can be accessed from a rear-side storage compartment for the top 16 is recorded. The folding top 12 comprises a folding top linkage 18 which, based on a vertical central longitudinal plane of the folding top, comprises a link arrangement 20 on both sides, which is pivotably mounted on a respective main bearing 22 fixed to the vehicle. For driving purposes, a drive motor 24 is arranged on each of the main bearings 22, which can be in the form of an electric motor and acts on a main link of the relevant link arrangement.
Des Weiteren umfasst das Verdeck 12 einen Verdeckbezug 26, welcher mittels des Verdeckgestänges 18 aufspannbar ist, um die in Figur 1 dargestellte Verdeckstellung zu realisieren. Der Verdeckbezug 26 erstreckt sich in der Verdeckstellung des Verdecks 12 zwischen einem bugseitigen, sich zwischen den beidseits angeordneten Lenkeranord- nungen 20 erstreckenden Frontspriegel 28 und einem heckseitigen Spannbügel 30, welcher sich ebenfalls zwischen den beidseits angeordneten Lenkeranordnungen 20 erstreckt und einen heckseitigen Rand des Verdeckbezugs 26 definiert. An den seitlichen Rändern ist der Verdeckbezug 26 jeweils von einer seitlichen, sich in Fahrzeuglängsrichtung erstreckenden Dichtungsanordnung 32 begrenzt. In der Verdeckstellung wirken die Dichtungsanordnungen 32 mit nicht näher dargestellten Seitenfenstern des Cabrioletfahrzeugs 10 zusammen. Furthermore, the top 12 includes a top cover 26, which can be opened by means of the top linkage 18 in order to realize the top position shown in FIG. The top cover 26 extends in the top position of the top 12 between a bow-side, located between the handlebar arrangement on both sides 20 extending front bow 28 and a rear-side clamping bracket 30, which also extends between the link assemblies 20 arranged on both sides and a rear-side edge of the top cover 26 defines. The top cloth 26 is delimited at the lateral edges by a lateral sealing arrangement 32 extending in the longitudinal direction of the vehicle. In the top position, the sealing arrangements 32 interact with side windows of the convertible vehicle 10 (not shown in detail).
Der Verdeckbezug 26 umfasst eine Außenhaut 34, welche faltbar und wetterfest, d. h. wasser- und winddicht, ausgebildet ist. Zudem umfasst der Verdeckbezug 26 einen Innenhimmel 36, welcher in der Schließstellung des Verdecks 12 eine vom Fahrzeuginnenraum 14 aus sichtbare Sichtfläche des Verdecks 12 bildet. The top cloth 26 includes an outer skin 34 which is foldable and weatherproof, i. H. waterproof and windproof. In addition, the top cover 26 includes an inner liner 36 which, when the top 12 is in the closed position, forms a visible surface of the top 12 that is visible from the vehicle interior 14 .
Wie Figur 2 zu entnehmen ist, hat die Außenhaut 34 einen Schichtaufbau 38, der an seiner der Fahrzeugumgebung abgewandten Innenseite einen kapazitiven Sensor 40 aufweist, der Bestandteil einer Einklemmschutzeinrichtung 42 ist, mittels der verhindert werden kann, dass sich Personen bei einem Verstellen des Verdecks 12 verletzen. Der Schichtaufbau 38 umfasst, wie bei üblichen Außenhäuten eines Verdeckbezugs, eine die äußere Sichtfläche des Verdecks 12 bildende Außenschicht 44 aus einem textilen Material, an die eine Gummischicht 46 grenzt, welche wiederum von einer Innenschicht 48 gefolgt ist, die ebenfalls aus einem textilen Material gebildet ist. Zur Ausbildung des kapazitiven Sensors 40 ist auf der Innenschicht 48 eine leitfähige Schicht 50 angeordnet, die aus Graphen gebildet ist, das auf die Innenschicht 48 aufgesprüht ist. Auf der eine erste Elektrode des kapazitiven Sensors 40 bildenden, leitfähigen Schicht 50 ist eine elektrisch isolierende Schicht 52 angeordnet, die ein Dielektrikum des kapazitiven Sensors 40 bildet. Zur Ausbildung einer zweiten Elektrode des kapazitiven Sensors 40 ist die elektrisch isolierende Schicht 52 von einer weiteren elektrisch leitfähigen Schicht 54 gefolgt, welche aus Graphen gebildet ist, das auf die elektrisch isolierende Schicht 52 aufgesprüht ist. Die beiden elektrisch leitfähigen, jeweils eine Elektrode bildenden leitfähigen Schichten 50 und 54 des kapazitiven Sensors 40 sind über Anschlusselemente bzw. Kollektoren 56 und 58 sowie Messleitungen 60 und 62 mit einer Mess- und Steuerelektronik 64 verbunden, die einen üblichen Schaltkreis zur Messung von Kapazitäten umfasst. Die Mess- und Steuerelektronik 64 ist über eine Steuerleitung 66 mit den Antriebsmotoren 24 des Verdeckgestänges 18 verbunden, so dass diese bei Erkennen einer Einklemmsituation mittels der Mess- und Steuerelektronik 64 gestoppt oder reversiert werden können. As can be seen from Figure 2, the outer skin 34 has a layer structure 38, which has a capacitive sensor 40 on its inner side facing away from the vehicle environment, which is part of an anti-trap device 42, by means of which it is possible to prevent persons from moving when the convertible top 12 violate. As with conventional outer skins of a top cover, the layer structure 38 comprises an outer layer 44 made of a textile material that forms the outer visible surface of the top 12 and is bordered by a rubber layer 46, which in turn is followed by an inner layer 48 that is also made of a textile material is. In order to form the capacitive sensor 40 , a conductive layer 50 is arranged on the inner layer 48 and is formed from graphene which is sprayed onto the inner layer 48 . An electrically insulating layer 52 , which forms a dielectric of capacitive sensor 40 , is arranged on conductive layer 50 , which forms a first electrode of capacitive sensor 40 . In order to form a second electrode of the capacitive sensor 40, the electrically insulating layer 52 is followed by a further electrically conductive layer 54, which is formed from graphene which is sprayed onto the electrically insulating layer 52. The two electrically conductive layers 50 and 54 of the capacitive sensor 40, each forming an electrode, are connected via connecting elements or collectors 56 and 58 and measuring lines 60 and 62 to measuring and control electronics 64, which are a conventional circuit for measuring capacitances includes. The measurement and control electronics 64 are connected to the drive motors 24 of the top linkage 18 via a control line 66 so that they can be stopped or reversed by means of the measurement and control electronics 64 when a jamming situation is detected.
Der kapazitive Sensor 40, der durch die leitfähigen Schichten 50 und 54 des Schichtaufbaus 38 der Außenhaut 34 realisiert ist, verändert beim Verstellen des Verdecks 12 zwischen der Verdeckstellung und der Ablagestellung seine Kapazität. Diese Kapazität wird mittels der Mess- und Steuerelektronik 64 erfasst und mit einer Sollwertkurve verglichen. Wenn sich nun beim Verstellen des Verdecks 12 ein Gegenstand oder ein Körperteil einer Person dem Verdeckbezug 26 nähert und insbesondere diesen berührt, verändert sich die Kapazität des kapazitiven Sensors 40 signifikant bzw. sprunghaft, so dass mittels der Mess- und Steuerelektronik 64 eine signifikante Abweichung von der Sollwertkurve erkannt wird. Diese Abweichung interpretiert die Mess- und Steuerelektronik 64 als Einklemmsituation, weswegen über die Steuerleitung 66 die Antriebsmotoren 24 angesteuert und gestoppt werden. The capacitive sensor 40, which is implemented by the conductive layers 50 and 54 of the layer structure 38 of the outer skin 34, changes its capacitance when the top 12 is adjusted between the top position and the stowed position. This capacitance is recorded by the measurement and control electronics 64 and compared with a setpoint curve. If an object or a part of a person's body approaches and in particular touches the top cloth 26 when the top 12 is being adjusted, the capacitance of the capacitive sensor 40 changes significantly or abruptly, so that the measuring and control electronics 64 detect a significant deviation from of the setpoint curve is detected. The measurement and control electronics 64 interpret this deviation as a pinching situation, which is why the drive motors 24 are activated and stopped via the control line 66 .
In Figur 3 ist eine alternative Ausführungsform einer Außenhaut 34' eines Verdeckbezugs eines Verdecks der in Figur 1 dargestellten Art gezeigt. Die Außenhaut 34' hat einen Schichtaufbau 38' mit einer textilen Außenschicht 44, die von einer Gummischicht 46' gefolgt ist, an welche wiederum eine textile Innenschicht 48 angebunden ist. An die Innenseite der textilen Innenschicht 48 ist eine elektrisch leitfähige Schicht 50 angebunden, die aus aufgesprühtem Graphen gebildet ist. Die Gummischicht 46' ist aus einem Werkstoff gebildet, der elektrisch leitfähig ist, so dass sie eine erste Elektrode eines kapazitiven Sensors 40' bildet. Eine zweite Elektrode des kapazitiven Sensors 40' ist durch die leitfähige Schicht 50 gebildet. Die Gummischicht 46' und die leitfähige Schicht 50 sind über Messleitungen 60 und 62 mit einer Mess- und Steuerelektronik 64 verbunden, welche eine Kapazität des kapazitiven Sensors 40' bzw. eine Änderung der Kapazität des kapazitiven Sensors 40' ermitteln kann und mit den Antriebsmotoren des betreffenden Verdecks in Verbindung steht. Auch der kapazitive Sensor 40' ist Bestandteil einer Einklemmschutzeinrichtung, mittels der auf kapazitivem Wege in der oben beschriebenen Weise eine Einklemmsituation erkannt werden kann, so dass mittels der Mess- und Steuerelektronik 64 die Antriebsmotoren des Verdecks entsprechend angesteuert werden können. FIG. 3 shows an alternative embodiment of an outer skin 34′ of a top cover of a top of the type shown in FIG. The outer skin 34' has a layered structure 38' with a textile outer layer 44, which is followed by a rubber layer 46', to which in turn a textile inner layer 48 is attached. An electrically conductive layer 50 formed from sprayed-on graphene is bonded to the inside of the textile inner layer 48 . The rubber layer 46' is formed from a material that is electrically conductive so that it forms a first electrode of a capacitive sensor 40'. A second electrode of the capacitive sensor 40 ′ is formed by the conductive layer 50 . The rubber layer 46' and the conductive layer 50 are connected via measuring lines 60 and 62 to measuring and control electronics 64, which can determine a capacitance of the capacitive sensor 40' or a change in the capacitance of the capacitive sensor 40' and communicate with the drive motors of the concerned convertible top is connected. The capacitive sensor 40 'is part of an anti-trap device, by means of the capacitive way in the manner described above, a pinch situation can be detected, so that by means of Measurement and control electronics 64, the drive motors of the top can be controlled accordingly.
