Description

Beschreibung description

Haptische Bedieneinrichtung in einem Kraftfahrzeug Haptic operating device in a motor vehicle

Die Erfindung betrifft eine haptische Bedieneinrichtung in einem Kraftfahrzeug, bei der eine Eingabeeinheit von mindestens einem mit der Eingabeeinheit gekoppelten Aktor bewegbar ist, wobei die Eingabeeinheit eine Oberfläche aufweist und wobei die Oberfläche von einem Eingabeorgan eines Bedieners berührbar ist. Aus dem Stand der Technik sind derartige sogenannte haptische Bedieneinrichtungen bekannt, bei denen auf einem sogenannten Touchpad oder Touchscreen mittels eines Eingabeorgans, beispielsweise eines Fingers eines Bedieners, Eingaben getätigt werden können und der Bediener in seinem Finger eine fühlbare Rückmeldung erhält, indem die Oberfläche des Touchpads bzw. Touchscreens senkrecht oder parallel zu ihrer Oberfläche bewegt werden und diese Bewegung mittels des Fingers wahrnehmbar ist. So kann dem Bediener eine Rückmeldung geben werden, dass eine Berührung des Touchpads oder Touchscreens von der Bedieneinrichtung erkannt wurde, ohne dass der Bediener auf den Touchscreen oder das Touchpad schauen muss und so weniger von seiner eigentlichen Fahraufgabe im Kraftfahrzeug abgelenkt wird. The invention relates to a haptic operating device in a motor vehicle, in which an input unit of at least one actuator coupled to the input unit can be moved, the input unit having a surface and the surface being touchable by an input element of an operator. Such so-called haptic operating devices are known from the prior art, in which inputs can be made on a so-called touchpad or touchscreen by means of an input element, for example an operator's finger, and the operator receives tactile feedback in his finger by touching the surface of the touchpad or touchscreens are moved perpendicular or parallel to their surface and this movement can be perceived by means of the finger. Thus, the operator can be given feedback that a touch of the touchpad or touchscreen has been recognized by the operating device without the operator having to look at the touchscreen or the touchpad and thus being less distracted from his actual driving task in the motor vehicle.

Im Laufe der Entwicklung wurden die Touchpads bzw. Touchscreens immer größer, so dass bei größeren Touchpads bzw. Touchscreens durch eine Bewegung der Touchpads bzw. Touchscreens zum einen eine unerwünschte Wankbewegung des Kraftfahrzeugs erfolgt und weiterhin durch die stoßartige Bewegung ein dumpfer Schlag hörbar ist. In the course of development, the touchpads or touchscreens have become larger and larger, so that on larger touchpads or touchscreens, on the one hand, an undesired rolling movement of the motor vehicle occurs due to a movement of the touchpads or touchscreens and a thud is still audible due to the jerky movement.

Aufgabe der Erfindung ist es daher eine haptische Bedieneinrichtung für ein Kraftfahrzeug anzugeben, bei dem es auch bei der Bewegung eines größeren Touchpads bzw. Touchscreens nicht zu einer Wankbewegung und nicht zu einem dumpfen Schlag kommt. The object of the invention is therefore to specify a haptic operating device for a motor vehicle in which there is no rolling movement and no thud even when a larger touchpad or touchscreen is moved.

Diese Aufgabe wird dadurch erreicht, dass die Eingabeeinheit und der mindestens eine Aktor beweglich zu dem Kraftfahrzeug gelagert sind. This object is achieved in that the input unit and the at least one actuator are movably mounted in relation to the motor vehicle.

Hierdurch wird bewirkt, dass die auftretenden Impulse nicht in das Kraftfahrzeugeingeleitet werden und die Impulse der Aktoreinheit und der Eingabeeinheit sich zumindest teilweise aufheben, da sie in entgegengesetzte Richtungen wirken. Wenn die Aktoreinheit und die Eingabeeinheit die gleiche Resonanzfrequenz aufweisen heben sich die gegensätzlichen Impulse noch besser auf. This has the effect that the pulses that occur are not introduced into the motor vehicle and that the pulses of the actuator unit and the input unit at least partially cancel each other out, since they act in opposite directions. If the actuator unit and the input unit have the same resonance frequency, the opposing pulses cancel each other out even better.

Wenn die Eingabeeinheit mit einer ersten Federvorrichtung und die Aktoreinheit mit einer zweiten Federvorrichtung gelagert sind können die Resonanzfrequenzen der Eingabeeinheit und der Aktoreinheit besonders gut aufeinander abgestimmt werden. If the input unit is mounted with a first spring device and the actuator unit is mounted with a second spring device, the resonance frequencies of the input unit and the actuator unit can be coordinated particularly well with one another.

Besonders gut wird die Abstimmung der Resonanzfrequenzen, wenn gilt: The tuning of the resonance frequencies is particularly good if:

Steifigkeit der ersten Federvorrichtung/Masse der Eingabeeinheit = Stiffness of the first spring device / mass of the input unit =

Steifigkeit der zweiten Federvorrichtung/Masse der Aktoreinheit. Rigidity of the second spring device / mass of the actuator unit.

Wenn die Eingabeeinheit eine Anzeige aufweist können mit der Eingabeeinheit die unterschiedlichsten Programme, Programmteile und/ oder Werte mit der Eingabeeinheit bedient werden und der Bediener gleichzeitig auf die aktuell auswählbaren Programme, Programmteile und/ oder Werte hingewiesen werden und angezeigt werden, welche Stelle der Anzeige er berühren muss, um bestimmte gewünschte Reaktionen einer von der Bedieneinheit angesteuerten elektrischen oder elektronischen Vorrichtung zu bewirken. If the input unit has a display, a wide variety of programs, program parts and / or values can be operated with the input unit and the operator can be informed of the currently selectable programs, program parts and / or values at the same time and which point of the display is displayed must touch in order to bring about certain desired reactions of an electrical or electronic device controlled by the operating unit.

Besonders einfach und preiswert ist die Anzeige, wenn es sich um eine elektrooptische Anzeige handelt. Es können aber auch elektromechanische oder nicht veränderbare Anzeigen vorgesehen sein. Eine nicht veränderbare Anzeige kann beispielsweise durch eine Bedruckung oder sonstige Beschichtung der Oberfläche der Eingabeeinheit realisiert sein. The display is particularly simple and inexpensive when it is an electro-optical display. However, electromechanical or non-changeable displays can also be provided. A display that cannot be changed can be implemented, for example, by printing or other coating on the surface of the input unit.

Wenn die Eingabeeinheit senkrecht zu ihrer Oberfläche bewegbar ist kann die Bewegung gut von einem Finger einer Person, die die haptische Bedieneinrichtung verwendet gut als solche erfasst werden. If the input unit can be moved perpendicular to its surface, the movement can easily be detected as such by a finger of a person using the haptic operating device.

Wenn die Eingabeeinheit parallel zu ihrer Oberfläche bewegbar ist, kann unter Umständen eine im Gegensatz zur senkrechten Bewegung einfachere Lösung des mechanischen Aufbaus der haptischen Bedieneinrichtung gefunden werden. Bei nur kleinen Bewegungswegen kann eine Fingerspitze nicht auflösen, ob die Eingabeeinheit senkrecht oder parallel zu ihrer Oberfläche bewegt wird. Wenn die haptische Bedieneinrichtung über Lager zusätzlich gelagert ist können Bewegungsgrade der Bedieneinheit genau definiert werden. Die Lager können beispielsweise als Rollenlager, Kugellager oder Gleitlager ausgestaltet sein. If the input unit can be moved parallel to its surface, a simpler solution for the mechanical structure of the haptic operating device can be found under certain circumstances, as opposed to vertical movement. With only small movement paths, a fingertip cannot determine whether the input unit is being moved perpendicularly or parallel to its surface. If the haptic operating device is additionally supported by bearings, degrees of movement of the operating unit can be precisely defined. The bearings can be designed, for example, as roller bearings, ball bearings or slide bearings.

Die Erfindung wird nachfolgend anhand der Figuren näher erläutert. The invention is explained in more detail below with reference to the figures.

In Figur 1 erkennt man ein erstes Ausführungsbeispiel einer erfindungsgemäßen haptischen Bedieneinrichtung mit einer Eingabeeinheit 100, eine mit der Eingabeeinheit 100 gekoppelten Aktor-Einheit 200, zwei erste Federelemente 300, ein zweites Federelement 400 und ein Gehäuse 600. Die Eingabeeinheit 100 weist ein Koppelteil 111 auf. Die Aktor-Einheit 200 weist einen einzigen Aktor auf, der über das Koppelteil 111 mit der Eingabeeinheit 100 gekoppelt ist. Weiterhin ist die Aktor Einheit 200 über das zweite Federelement 400 mit dem Gehäuse 600 verbunden. Die Eingabeeinheit 100 ist weiterhin über die zwei ersten Federelemente 300 mit dem Gehäuse 600 verbunden. Auf eine zusätzliche Lagerung der Eingabeeinheit 100 kann gegebenenfalls verzichtet werden. Es ist auch möglich, ein oder mehrere Lager zwischen der Eingabeeinheit 100 und dem Gehäuse 600 vorzusehen, um eine seitliche Bewegung der Eingabeeinheit 100 zu verhindern. Diese Lager können beispielsweise als Gleitlager, Kugellager oder Rollenlager ausgestaltet sein. Ein Finger F eines ansonsten nicht dargestellten Bedieners der Bedieneinrichtung berührt die Oberfläche der Eingabeeinheit 100. Diese Berührung wird von einer nicht dargestellten Sensorik erfasst, ausgewertet und die Aktor-Einheit 200 angesteuert, so dass die Aktor Einheit 200 die Eingabeeinheit 100 über das Koppelteil 111 bewegt. Hierbei führen die Aktor- Einheit 200 und die Eingabeeinheit 100 Bewegungen in entgegengesetzte Richtungen aus, sodass sich ihre Impulse aufheben. Die Aktor-Einheit 200 kann die Eingabeeinheit 100 über das Koppelteil 111 anziehen oder abstoßen. Das Koppelteil 111 kann wie dargestellt als Teil der Bedieneinheit 100 ausgestaltet sein. Es kann aber auch als separates Bauteil ausgestaltet sein, das mit der Eingabeeinheit 100 verbunden ist. Das Gehäuse 600 kann wie dargestellt ein separates Gehäuse sein, welches zum Einbau in eine Karosserie eines Kraftfahrzeuges vorgesehen ist. Das Gehäuse 600 kann aber auch bereits Teil eines Karosserie-Aufbaus eines ansonsten nicht dargestellten Kraftfahrzeuges sein. Die ersten Federelemente 300 und das zweite Federelement 400 sind vorteilhafter Weise so ausgestaltet, dass sie die in Patentanspruch 5 beanspruchten Bedingungen erfüllen. In der Eingabeeinheit 100 kann eine nicht dargestellte Anzeige angeordnet sein, die von dem möglichen Bediener der Eingabeeinheit 100 wahrnehmbar ist. Diese Anzeige kann beispielsweise in einer Bedruckung der Oberfläche der Eingabeeinheit 100 bestehen. Besonders vorteilhaft ist eine elektrooptische Anzeige, da dann unterschiedliche auswählbare Programme, Unterprogramme und/oder Werte darstellbar und durch die Bedieneinheit einstellbar sind. Die Eingabeeinheit 100 und die Aktoreinheit 200 sind dabei vorteilhafterweise jeweils so gelagert, dass sie in Funktionsrichtung des Aktors 200 beweglich sind, in den anderen Richtungen aber fixiert. Die nicht dargestellten Lager können beispielsweise als Kugellager, Rollenlager oder Gleitlager ausgestaltet sein. Dies gilt auch für die nachfolgenden Ausführungsbeispiele in den Figuren 2 und 3. FIG. 1 shows a first exemplary embodiment of a haptic operating device according to the invention with an input unit 100, an actuator unit 200 coupled to the input unit 100, two first spring elements 300, a second spring element 400 and a housing 600. The input unit 100 has a coupling part 111 . The actuator unit 200 has a single actuator which is coupled to the input unit 100 via the coupling part 111. Furthermore, the actuator unit 200 is connected to the housing 600 via the second spring element 400. The input unit 100 is also connected to the housing 600 via the two first spring elements 300. An additional storage of the input unit 100 can possibly be dispensed with. It is also possible to provide one or more bearings between the input unit 100 and the housing 600 in order to prevent lateral movement of the input unit 100. These bearings can be designed, for example, as plain bearings, ball bearings or roller bearings. A finger F of an operator of the operating device (otherwise not shown) touches the surface of the input unit 100. This contact is detected and evaluated by a sensor system (not shown) and the actuator unit 200 is activated so that the actuator unit 200 moves the input unit 100 via the coupling part 111 . Here, the actuator unit 200 and the input unit 100 perform movements in opposite directions, so that their pulses cancel each other out. The actuator unit 200 can attract or repel the input unit 100 via the coupling part 111. The Coupling part 111 can be configured as part of the operating unit 100, as shown. However, it can also be designed as a separate component that is connected to the input unit 100. The housing 600 can, as shown, be a separate housing which is provided for installation in a body of a motor vehicle. The housing 600 can, however, also already be part of a body structure of a motor vehicle that is otherwise not shown. The first spring elements 300 and the second spring element 400 are advantageously designed in such a way that they meet the conditions claimed in claim 5. A display, not shown, which can be perceived by the possible operator of the input unit 100, can be arranged in the input unit 100. This display can consist, for example, of printing on the surface of the input unit 100. An electro-optical display is particularly advantageous since different selectable programs, sub-programs and / or values can then be displayed and set using the operating unit. The input unit 100 and the actuator unit 200 are advantageously each mounted in such a way that they can be moved in the functional direction of the actuator 200, but are fixed in the other directions. The bearings, not shown, can be designed, for example, as ball bearings, roller bearings or plain bearings. This also applies to the following exemplary embodiments in FIGS. 2 and 3.

Das Ausführungsbeispiel in Figur 2 unterscheidet sich von dem Ausführungsbeispiel in Figur 1 dadurch, dass die Aktoreinheit 200 zwei Aktoren und zwei zweite Federelemente 400 aufweist. Weiterhin weist die Eingabeeinheit 100 zwei Koppelteile 112 auf, so dass die Eingabeeinheit 100 von zwei Aktoren bewegt wird. Die Bewegungsabläufe der Eingabeeinheit 100 und der Aktor-Einheit 200 sind wie zuvor zu Figur 1 beschrieben. The exemplary embodiment in FIG. 2 differs from the exemplary embodiment in FIG. 1 in that the actuator unit 200 has two actuators and two second spring elements 400. Furthermore, the input unit 100 has two coupling parts 112, so that the input unit 100 is moved by two actuators. The movement sequences of the input unit 100 and the actuator unit 200 are as described above for FIG.

Das Ausführungsbeispiel in Figur 3 unterscheidet sich von dem Ausführungsbeispiel in Figur 2 dadurch, dass die Koppelelemente 113 nicht im rechten Winkel zur Eingabeeinheit 100 wie in Figur 2 angeordnet sind, sondern im spitzen Winkel. Hierdurch ändert sich auch die Anordnung der Aktoren der Aktoreinheit 200. Da sich die Kräfte der Aktoren der Aktoreinheit 200 in seitlicher Richtung gegenseitig aufheben, erfolgt eine Bewegung der Eingabeeinheit100 senkrecht zur Oberfläche der Eingabeeinheit 100. Der Vorteil dieses Aufbaus ist der im Vergleich des Ausführungsbeispiels nach Figur 2 der insgesamt flachere Aufbau. Die Bewegungsabläufe der Eingabeeinheit 100 und der Aktor-Einheit 200 sind wie zuvor zu Figur 1 beschrieben. The exemplary embodiment in FIG. 3 differs from the exemplary embodiment in FIG. 2 in that the coupling elements 113 are not arranged at right angles to the input unit 100 as in FIG. 2, but at an acute angle. This also changes the arrangement of the actuators of the actuator unit 200. Since the forces of the actuators of the actuator unit 200 cancel each other out in the lateral direction, the input unit 100 moves perpendicular to the surface of the input unit 100 Figure 2 the overall flatter structure. The movement sequences of the input unit 100 and the actuator unit 200 are as described above for FIG.

In Figur 4 erkennt man eine Eingabeeinheit 104 mit einem Koppelteil 114, eine Aktor Einheit 204, ein erstes Federelement 304, ein zweites Federelement 404und ein Gehäuse 600. Die Eingabeeinheit 104 ist über das erste Federelement 304 und der Aktor 204 über das zweite Federelement 404 mit dem Gehäuse 600 verbunden. Weiterhin sind die Eingabeeinheit 104 und die Aktoreinheit 204 über nicht dargestellte Lager gelagert. Wenn die Aktor-Einheit 204 betätigt wird zieht sie entweder die Eingabeeinheit 104 an oder stößt sie ab, so dass die Eingabeeinheit 104 parallel zu ihrer Oberfläche, in Figur 4 also nach rechts oder links, bewegt wird. Die von der Eingabeeinheit 104 und der Aktor-Einheit 204 erzeugten Impulse heben sich auf, sodass von der Ausführungsbeispiel der dargestellten erfindungsgemäßen Bedieneinrichtung kein Impuls in das Gehäuse 600 eingeleitet wird und auch kein Geräusch eines dumpfen Schlages erzeugt wird. Die nicht dargestellten Lager können beispielsweise als Kugellager, Rollenlager oder Gleitlager ausgestaltet sein. Die Eingabeeinheit 104 und der Aktor 204 sind dabei jeweils so gelagert, dass sie in Funktionsrichtung des Aktors 204 beweglich sind, in den anderen Richtungen aber fixiert. Die Eingabeeinheit 100 ist vorteilhafterweise so gelagert, dass sie in Bewegungsrichtung der Eingabeeinheit 100 beweglich sind, in den anderen Richtungen aber fixiert. 4 shows an input unit 104 with a coupling part 114, an actuator unit 204, a first spring element 304, a second spring element 404 and a housing 600. The input unit 104 is connected via the first spring element 304 and the actuator 204 via the second spring element 404 connected to the housing 600. Furthermore, the input unit 104 and the actuator unit 204 are supported by bearings (not shown). When the actuator unit 204 is actuated, it either attracts the input unit 104 or pushes it off, so that the input unit 104 is moved parallel to its surface, that is to say to the right or left in FIG. 4. The pulses generated by the input unit 104 and the actuator unit 204 cancel each other out, so that no pulse is introduced into the housing 600 by the exemplary embodiment of the illustrated operating device according to the invention and no thump sound is generated either. The bearings, not shown, can be designed, for example, as ball bearings, roller bearings or plain bearings. The input unit 104 and the actuator 204 are each mounted in such a way that they can move in the functional direction of the actuator 204, but are fixed in the other directions. The input unit 100 is advantageously mounted such that it can be moved in the direction of movement of the input unit 100, but is fixed in the other directions.
