Description

Aktoranordnunq zur Ansteuerunq einer Kupplung in einem Kraftfahrzeug  Aktoranordnunq for driving a clutch in a motor vehicle
Die Erfindung betrifft eine Aktoranordnung zur Ansteuerung einer Kupplung in einem Kraft fahrzeug, umfassend einen mit einer Versorgungsspannung verbundenen Aktors zur Betäti gung der Kupplung. The invention relates to an actuator assembly for driving a clutch in a motor vehicle, comprising a connected to a supply voltage actuator for Actuate supply of the clutch.
In Kupplungsbetätigungssystemen, welche einen Aktor zum Antrieb der Kupplung umfassen, ist der Aktor mit der Fahrzeugbatterie zur Energieversorgung verbunden. Es kann auftreten, dass die Spannung der Fahrzeugbatterie abfällt, so dass die Kupplung nicht mehr betätigt werden kann. Für eine sogenannte„Normally open“-Kupplung, welche im unbetätigten Zu stand immer geöffnet ist, oder für ein selbsthaltendes System, wird insbesondere immer dann eine kritische Situation hervorrufen, wenn sich beispielsweise das Fahrzeug in einem Segel vorgang befindet. Segeln bedeutet dabei, dass der Verbrennungsmotor bei geöffneter Kupp lung in einem Leerlaufmodus betrieben wird oder gar abgeschaltet ist. Da bei gestörter Batte riespannung die„normally open“-Kupplung oder das selbsthaltende System nicht mehr ge schlossen werden kann, kann auch der Verbrennungsmotor nach Abschluss des Segelvor ganges nicht wieder gestartet werden, indem der Aktor die Kupplung betätigt und somit den Verbrennungsmotor anschleppt. In clutch actuation systems which include an actuator for driving the clutch, the actuator is connected to the vehicle battery for power supply. It may happen that the voltage of the vehicle battery drops, so that the clutch can not be operated. For a so-called "normally open" coupling, which is always open in the unactuated state, or for a self-holding system, in particular will always cause a critical situation when, for example, the vehicle is in a sail process. Sailing means that the engine is operated in an open mode with the clutch open or even switched off. As with disturbed Batte riespannung the "normally open" coupling or the self-holding system can not be closed ge, the internal combustion engine after completion of Segelvor ganges can not be restarted by the actuator actuates the clutch and thus entrains the engine.
Der Erfindung liegt die Aufgabe zugrunde, eine Aktoranordnung zur Ansteuerung einer Kupp lung anzugeben, bei welcher sicherheitskritische Situationen beim Ausfall einer Versorgungs spannung des Kraftfahrzeuges verhindert werden. The invention has for its object to provide an actuator arrangement for controlling a hitch be in which safety-critical situations in case of failure of a supply voltage of the motor vehicle can be prevented.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass ein Energiespeicher mit dem Aktor zur Aufrechterhaltung der Aktorfunktion bei einem Spannungsabfall an der Versorgungsspannung verbunden ist. Dadurch wird gewährleistet, dass immer ein Backup vorhanden ist, welches bei Abfall der Spannung an der Fahrzeugbatterie eine Spannung bereitstellt, so dass die Kupp lung weiter betrieben werden kann. Dies ist insbesondere für Segelvorgänge des Fahrzeuges von Bedeutung, wo bei abgeschaltetem Verbrennungsmotor dieser durch Schließen der Kupplung wieder gestartet werden muss. According to the invention, the object is achieved in that an energy store is connected to the actuator for maintaining the actuator function in the event of a voltage drop at the supply voltage. This ensures that there is always a backup, which provides a voltage drop in the voltage at the vehicle battery, so that the hitch be able to continue operation. This is particularly important for sailing operations of the vehicle, where when the internal combustion engine this has to be restarted by closing the clutch.
Vorteilhafterweise ist der Energiespeicher in ein Gehäuse der Aktoranordnung integriert. Advantageously, the energy store is integrated in a housing of the actuator arrangement.
Dadurch wird kein zusätzlicher Bauraum im Fahrzeug benötigt, was zu einem platzsparenden Einsatz des Energiespeichers führt. In einer Ausgestaltung ist in dem Energiespeicher Energie für eine mindestens einmalige Be tätigung der Kupplung gespeichert. Dies ermöglicht eine relativ kleine Ausgestaltung des Energiespeichers, weshalb er insbesondere in dem Gehäuse der Aktoranordnung positionier bar ist. Darüber hinaus ist gewährleistet, dass der Verbrennungsmotor nach Abschluss des Segelvorganges wieder gestartet werden kann. As a result, no additional space is required in the vehicle, resulting in a space-saving use of energy storage. In one embodiment, energy for at least one Be actuation of the clutch is stored in the energy storage. This allows a relatively small configuration of the energy storage, which is why he is positioning bar in particular in the housing of the actuator assembly. In addition, it is ensured that the internal combustion engine can be restarted after completion of the sailing process.
In einer Variante ist der Energiespeicher im Steuergerät des Aktors zwischen einer Polungs schutzeinheit zum Abkoppeln der Versorgungsspannung und einer Motorelektronik, beste hend aus einer Ansteuerung eines Elektromotors sowie einer Logikeinheit mit einer internen Stromversorgung, geschaltet. Die Polungsschutzeinheit, welche insbesondere einen MOS- FET oder einen anderen Leistungselektronik-Transistor umfasst, kann im Falle eines Span nungsabfalls die Verbindung der Versorgungsspannung zur Motorelektronik trennen und den Energiespeicher an die interne Stromversorgung ankoppeln. Die Polschutzschaltung ist in der Regel aus Gründen des Bauteileschutzes im Steuergerät bereits vorhanden. In a variant of the energy storage in the control unit of the actuator between a polarity protection unit for disconnecting the supply voltage and an engine electronics, best starting from a control of an electric motor and a logic unit with an internal power supply connected. The polarity protection unit, which in particular comprises a MOSFET or another power electronics transistor, can disconnect the connection of the supply voltage to the engine electronics in the event of a voltage drop and couple the energy store to the internal power supply. The pole protection circuit is usually already present for reasons of component protection in the control unit.
In einer Ausführungsform ist der Energiespeicher in einer Steuereinheit des Elektromotors an geordnet. Dadurch wird der von dem Energiespeicher beanspruchte Bauraum weiter redu ziert, da weder Steckkontakte noch ein eigenes Gehäuse nötig sind. In one embodiment, the energy storage is arranged in a control unit of the electric motor to. As a result, the space occupied by the energy storage space is further redu ed, since neither plug contacts nor a separate housing are needed.
In einer Weiterbildung ist der Energiespeicher als elektrischer Speicher ausgebildet. Als sol cher elektrischer Speicher können an sich bekannte, käuflich zu erwerbende Energiespeicher eingesetzt werden. In a development, the energy store is designed as an electrical memory. As sol cher electrical storage known per se, commercially available energy storage can be used.
Vorteilhafterweise umfasst der elektrische Energiespeicher eine Batterie oder einen Konden sator. Die Batterie kann beispielsweise wieder aufladbar sein. Als Kondensator können käuf lich erwerbliche Kondensatoren wie Gold-Cap oder Super-Cap verwendet werden, die aus der Consumer Electronic bekannt sind. Somit sind keine zusätzlichen Aufwendungen zur Herstel lung eines Energiespeichers speziell für ein Kraftfahrzeug notwendig. Advantageously, the electrical energy storage comprises a battery or a condensate capacitor. The battery can be rechargeable, for example. As a capacitor, purchasable Lich purchasable capacitors such as gold cap or super-cap can be used, which are known from consumer electronics. Thus, no additional expenses for the produc- tion of an energy storage especially for a motor vehicle are necessary.
In einer Alternative ist der Energiespeicher als mechanischer Speicher ausgebildet. Ein sol cher mechanischer Speicher kann jederzeit in seine Ausgangsposition zurückgebracht wer den, wodurch wieder neue Energie in diesem gespeichert ist. Der mechanische Speicher steht für eine weitere Verwendung zur Verfügung, so dass ein Austausch des mechanischen Spei chers nach einer Inanspruchnahme der in diesem Speicher gespeicherten Energie nicht not wendig ist. Vorteilhafterweise ist der mechanische Speicher durch Federn gebildet. Solche aus Federn gebildete mechanische Speicher sind sehr kostengünstig und platzsparend. In an alternative, the energy store is designed as a mechanical memory. Such a mechanical memory can be brought back to its original position at any time, which again stores new energy in it. The mechanical storage is available for further use, so that replacement of the mechanical storage chers is not agile to take advantage of the energy stored in this memory. Advantageously, the mechanical memory is formed by springs. Such formed from springs mechanical storage are very inexpensive and space-saving.
In einer Variante ist der Energiespeicher mit mindestens einem Aktor-internen Sensor zur Auf rechterhaltung der Sensorfunktion bei einem Spannungsabfall der Versorgungsspannung ver bunden. Ein solcher Aktor-interner Sensor kann beispielsweise ein Multiturn-Sensor sein, der die Positionen des Elektromotors misst, um daraus auf die Position des Aktors und somit die Position der von dem Aktor betätigten Kupplung zu schließen. In one variant, the energy storage device with at least one actuator-internal sensor for the maintenance of the sensor function in a voltage drop of the supply voltage a related party. Such an actuator-internal sensor can be, for example, a multi-turn sensor which measures the positions of the electric motor, in order to deduce the position of the actuator and thus the position of the actuator actuated clutch.
In einer Ausführungsform wird als Kupplung eine„normally open“- Kupplung verwendet. In one embodiment, a "normally open" coupling is used as the coupling.
In einer weiteren Ausführungsform wird ein selbsthaltendes System verwendet, wobei die Kupplung mechanisch„normally closed“ sein kann, der Aktor jedoch im Falle eines Span nungsabfalls die Position des Ausrücksystems annähernd beibehält und dadurch ein Schlie ßen der Kupplung verhindert. In another embodiment, a self-retaining system is used, wherein the clutch may be mechanically "normally closed", the actuator, however, in the case of a clamping voltage drop approximately retains the position of the disengagement system and thereby prevents a closing Shen of the coupling.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Eine davon soll anhand der in der Zeichnung dargestellten Figuren näher erläutert werden. The invention allows numerous embodiments. One of them will be explained in more detail with reference to the figures shown in the drawing.

Fig. 2 ein weiteres Ausführungsbeispiel der erfindungsgemäßen Aktoranordnung. Fig. 2 shows another embodiment of the actuator arrangement according to the invention.
In Fig. 1 ist ein erstes Ausführungsbeispiel der erfindungsgemäßen Aktoranordnung darge stellt. Die Aktoranordnung 1 umfasst dabei ein Steuergerät 2, welches mit einem Elektromotor 3 verbunden ist, der über eine Getriebeanordnung 4 eine„normally open“- Kupplung 5 an treibt. In dem Steuergerät 2 ist eine Polschutzeinheit 6 angeordnet, die mit einer eine Versor gungsspannung UB liefernden Fahrzeugbatterie verbunden ist. Die Polschutzeinheit 6 ist mit einer Motorelektronik 7 zum Antreiben des Elektromotors 3 gekoppelt. Zwischen der Pol schutzeinheit 6 und der Motorelektronik 7 ist, parallel zu diesen, ein Energiespeicher 8 ange ordnet, der als externes Gerät in der Aktoranordnung 1 positioniert ist und über Leitungen 9 mit dem Steuergerät 2 verbunden ist. Auf der Seite des Energiespeichers 8 kann eine nicht weiter dargestellte Spannungsregelung ausgebildet sein. In Fig. 2 ist eine Aktoranordnung 10 dargestellt, bei welcher der Energiespeicher 8 in dem Steuergerät 2 direkt zwischen die Polschutzeinheit 6 und die Motorelektronik 7 geschaltet ist. Dies stellt eine besonders platzsparende Anordnung für den Energiespeicher 8 dar, da die Ak toranordnung 10 besonders klein ausgebildet werden kann. Im vorliegenden Fall ist der Ener- giespeicher 8 als elektrischer Speicher ausgebildet, der als wieder aufladbare Batterie oder als Kondensator realisiert werden kann. Bei der Realisierung als Kondensator können die für die Comsumer-Industrie geläufigen Kondensatoren Super-Cap oder Gold-Cap eingesetzt werden. Dieser Energiespeicher 8 kann gleichzeitig zur Versorgung von in der Aktoranordnung 1 , 10 enthaltenen und nicht weiter dargestellten intelligenten Sensoren, wie Multiturnsensoren zur Bestimmung der Position des Elektromotors 3, genutzt werden. Wichtige Messergebnisse können dabei ohne Verwendung externer Energie in den Sensoren gespeichert werden. Dies ist insbesondere von Bedeutung für Bewegungssensoren, die den Aktorweg messen und wel- che bei einem Spannungsabfall die Information über die absolute Position des Aktors verlie ren, wodurch es zu einer fehlerhaften Ansteuerung der Kupplung kommen kann. In Fig. 1, a first embodiment of the actuator assembly according to the invention is Darge presents. The actuator assembly 1 includes a control unit 2, which is connected to an electric motor 3, which drives a "normally open" - clutch 5 via a gear assembly 4. In the control unit 2, a pole protection unit 6 is arranged, which is connected to a supply voltage UB supplying vehicle battery. The pole protection unit 6 is coupled to an engine electronics 7 for driving the electric motor 3. Between the pole protection unit 6 and the motor electronics 7, parallel to these, an energy storage device 8 is arranged, which is positioned as an external device in the actuator assembly 1 and is connected via lines 9 to the control unit 2. On the side of the energy storage 8, a voltage regulation not shown may be formed. 2, an actuator assembly 10 is shown, in which the energy storage 8 is connected in the control unit 2 directly between the polarity protection unit 6 and the engine electronics 7. This represents a particularly space-saving arrangement for the energy storage 8, since the Ak toranordnung 10 can be made very small. In the present case, the energy storage 8 is designed as an electrical memory, which can be realized as a rechargeable battery or as a capacitor. In the realization as a capacitor, the capacitors known for the Comsumer industry can be used Super-Cap or Gold-Cap. This energy store 8 can simultaneously be used to supply intelligent sensors contained in the actuator arrangement 1, 10 and not shown, such as multi-turn sensors for determining the position of the electric motor 3. Important measurement results can be stored in the sensors without using external energy. This is of particular importance for motion sensors which measure the actuator travel and which, in the event of a voltage drop, lose the information about the absolute position of the actuator, as a result of which faulty control of the clutch can occur.
Gleichzeitig kann auch ein in der Motorelektronik 7 enthaltener Prozessor mit Energie versorgt werden, wenn die Versorgungsspannung UB abfällt. Auch Zähler, welche die Abschaltzeit des Verbrennungsmotors messen, können mit einer Energie des Energiespeichers 8 versorgt werden. At the same time, a processor contained in the engine electronics 7 can also be supplied with energy when the supply voltage UB drops. Also, meters that measure the turn-off of the engine can be supplied with energy of the energy storage 8.
