FahrzeuglenkradVehicle steering wheel
Die Erfindung betrifft ein Fahrzeuglenkrad mit einer elektronischen Vorrichtung mit einem lenkradfesten Bedienelement, insbesondere zur Steuerung von Fahrzeugfunktionen in einem Fahrzeug.The invention relates to a vehicle steering wheel with an electronic device with a control element fixed to the steering wheel, in particular for controlling vehicle functions in a vehicle.
Moderne Kraftfahrzeuge weisen eine ständig zunehmende Anzahl von vom Fahrer einstellbaren Elementen auf. Darunter fallen z.B. altbekannte Elemente wie Blinker, Scheibenwischer oder verstellbare Spiegel, aber auch in letzten Jahren neu hinzugekommene Zusatzelemente wie Klimaanlagen, Navigationssysteme oder Mobiltelefone. Derartige Elemente werden im weiteren als Fahrzeugfunktionen aufweisende Elemente bezeichnet, da sie die Steuerung von Fahrzeugfunktionen erlauben. Unter einer Steuerung von Fahrzeugfunktionen wird im folgenden sowohl die Auslösung von bestimmten Funktionen (z.B. Einschalten des Lichts) als auch die Bedienung von Geräten und Zusatzelementen (z.B. das Wählen einer Nummer auf einem Mobiltelefon) sowie das Einstellen von Parametern (z.B. die Temperatur der Heizung) verstanden. Bislang war für jedes dieser Fahrzeugfunktionen aufweisenden Elemente eine eigene Steuervorrichtung vorgesehen, die meistens über einzelne, von den anderen Steuervorrichtungen unabhängige mechanische Schalter zu bedienen sind.Modern motor vehicles have an ever-increasing number of elements that can be adjusted by the driver. These include, for example, well-known elements such as indicators, windshield wipers or adjustable mirrors, but also additional elements that have been added in recent years such as air conditioning systems, navigation systems or mobile phones. Such elements are referred to below as elements that have vehicle functions, as they allow the control of vehicle functions. In the following, the control of vehicle functions is understood to mean both the triggering of certain functions (e.g. switching on the lights) and the operation of devices and additional elements (e.g. dialing a number on a mobile phone) as well as the setting of parameters (e.g. the temperature of the heating). Up to now, each of these elements that have vehicle functions had its own control device, which was usually operated via individual mechanical switches that were independent of the other control devices.
Mechanische Schalter in einem Fahrzeug sind relativ teuer, da sie z.B. unempfindlich gegen Vibrationen und vor Schmutz und FeuchtigkeitMechanical switches in a vehicle are relatively expensive because they are insensitive to vibrations and dirt and moisture.

geschützt sein müssen. Vor allem vielbenutzte Schalter müssen von hoher Qualität sein, um eine ausreichend hohe Lebensdauer zu gewährleisten.must be protected. Switches that are used frequently in particular must be of high quality in order to ensure a sufficiently long service life.
Ein Ziel der Erfindung ist es daher, die Anzahl an mechanischen Schaltern zur Bedienung von Fahrzeugfunktionen zu verringern.One aim of the invention is therefore to reduce the number of mechanical switches for operating vehicle functions.
Dies wird dadurch erreicht, daß das Bedienelement an einem oben genannten Lenkrad eine berührungsempfindliche Sensorfläche enthält, die bei einer Berührung ein elektronisches Signal erzeugt. Dieses von der Sensorfläche erzeugte elektronische Signal kann zur Steuerung beliebiger Fahrzeugfunktionen eingesetzt werden. Eine Sensorfläche kann vollständig ohne mechanische Komponenten auskommen, so daß keine anfälligen beweglichen Bauteile verwendet werden müssen. Da mit einer Sensorfläche beliebig viele Fahrzeugfunktionen bedient werden können, können auch die bisher vorgesehenen mechanischen Schalter der Steuerungen der einzelnen Fahrzeugfunktionen entfallen, was eine bedeutende Kostenersparnis bewirkt.This is achieved by the control element on the steering wheel mentioned above containing a touch-sensitive sensor surface that generates an electronic signal when touched. This electronic signal generated by the sensor surface can be used to control any vehicle function. A sensor surface can function completely without mechanical components, so that no vulnerable moving parts need to be used. Since any number of vehicle functions can be controlled with a sensor surface, the previously provided mechanical switches for controlling the individual vehicle functions can also be dispensed with, which results in significant cost savings.
Vorteilhaft erzeugt die Sensorfläche des Bedienelements bei Berührung Positionsdaten, die auf elektronischem Weg an eine Recheneinheit übertragen werden. Es ist günstig, wenn die elektronische Vorrichtung auch mit einer Anzeigevorrichtung verbunden ist, damit mit Fahrzeugfunktionen zusammenhängende Daten für den Fahrer sichtbar gemacht werden können. In einer bevorzugten Ausführungsform der Erfindung kann die Recheneinheit eine Darstellung eines bewegliches Element auf der Anzeigevorrichtung und eine Bewegung des Elements in Abhängigkeit von den übertragenen Positionsdaten hervorrufen. Das bewegliche Element ist bevorzugt ein Mauszeiger oder ein Cursor, dessen Bewegung auf der Anzeige über die Berührung des Sensorfeldes gesteuert werden kann. Dieses Verfahren ist seit langem von Personalcomputern bekannt. Auf diese Weise kann eine komfortable, einfach und intuitiv zu bedienende graphische Benutzeroberfläche, wie sie aus dem Bereich der Personalcomputer bekannt ist, zur Steuerung der Fahrzeugfunktionen eingesetzt werden.When touched, the sensor surface of the control element advantageously generates position data that is transmitted electronically to a computing unit. It is advantageous if the electronic device is also connected to a display device so that data related to vehicle functions can be made visible to the driver. In a preferred embodiment of the invention, the computing unit can display a movable element on the display device and cause the element to move depending on the transmitted position data. The movable element is preferably a mouse pointer or a cursor, the movement of which on the display can be controlled by touching the sensor field. This method has long been known from personal computers. In this way, a comfortable, simple and intuitive graphical user interface, as is known from the field of personal computers, can be used to control the vehicle functions.
Bevorzugt enthält das Bedienelement ein sogenanntes Touchpad.Preferably, the control element contains a so-called touchpad.
Touchpads sind aus der Laptoptechnologie bekannte Sensorflächen, über die durch Berührung richtungsabhängig z.B. ein Mauszeiger auf einem Bildschirm gesteuert werden kann. Besonders vorteilhaft ist dasTouchpads are sensor surfaces known from laptop technology, which can be used to control a mouse pointer on a screen by touching it in a direction-dependent manner. This is particularly advantageous

Touchpad am Lenkradkranz angeordnet. In diesem Fall kann eine kleine und damit kostengünstige Sensorfläche von nur wenigen Quadratzentimetern Ausdehnung eingesetzt werden, die vom Fahrer mit nur einem Finger bedienbar ist. Die Sensorfläche läßt sich damit in ihren Abmessungen den Dimensionen des Lenkradkranzes anpassen und kann ohne optische und taktile Beeinträchtigungen in den Lenkradkranz integriert werden. Um die Fahrsicherheit zu erhöhen, ist es günstig, die Sensorfläche an einer Stelle anzuordnen, die der Fahrer erreichen kann, ohne seinen gewohnten Griff am Lenkrad zu ändern. Eine derartige Sensorfläche kann auch an anderer Stelle in das Lenkrad intergriert werden.Touchpad arranged on the steering wheel rim. In this case, a small and therefore inexpensive sensor surface of just a few square centimeters can be used, which the driver can operate with just one finger. The sensor surface can thus be adapted to the dimensions of the steering wheel rim and can be integrated into the steering wheel rim without optical or tactile impairments. In order to increase driving safety, it is advisable to arrange the sensor surface in a place that the driver can reach without changing his usual grip on the steering wheel. A sensor surface of this type can also be integrated into the steering wheel at another location.
Besonders günstig ist es, wenn die Anzeigevorrichtung ein optisches Signal, das einer Darstellung der Steuerung der Fahrzeugfunktionen entspricht, auf eine Windschutzscheibe des Fahrzeugs projizieren kann, da dann der Fahrer den Blick während der Steuerung von Fahrzeugfunktionen nicht von der Straße nehmen muß. Eine solche Projektion kann auf bekanntem Weg erfolgen. Vor allem eine Kombination eines am Lenkradkranz angeordneten Touchpads mit einer auf die Windschutzscheibe projizierten Anzeige bietet ein Maximum an Komfort und Sicherheit für den Fahrer, da dieser weder die Hand vom Lenkrad noch die Augen von der Straße nehmen muß, um die gewünschten Änderungen an Fahrzeugfunktionen vorzunehmen.It is particularly advantageous if the display device can project an optical signal, which corresponds to a representation of the control of the vehicle functions, onto a windshield of the vehicle, since the driver then does not have to take his eyes off the road while controlling vehicle functions. Such a projection can be carried out in a known manner. In particular, a combination of a touch pad arranged on the steering wheel rim with a display projected onto the windshield offers maximum comfort and safety for the driver, since he does not have to take his hand off the steering wheel or his eyes off the road to make the desired changes to vehicle functions.
In einer anderen bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Bedienelement einen Touchscreen enthält. Ein Touchscreen, der ebenfalls aus der Computertechnologie bekannt ist, enthält eine Sensorfläche, die über einer Anzeigevorrichtung, z.B. einem LCD-Monitor, angebracht ist. Durch Berührung bestimmter Positionen auf dem Touchscreen kann ein Benutzer auf der Anzeigevorrichtung an dieser Stelle dargestellte Elemente auswählen. Bei der Auswahl eines dieser Elemente wird vorteilhafterweise über eine Recheneinheit wie der oben beschriebenen die entsprechende Fahrzeugfunktion ausgeführt oder ein entsprechendes Untermenü mit weiteren auswählbaren Elementen auf dem Touchscreen dargestellt. Ein Touchscreen dient gleichzeitig als Bedienelement und als Anzeige und läßt sich einfach bedienen. Vorzugsweise ist der Touchscreen im Bereich der Nabe oder einer Speiche des Lenkrads angeordnet, so daß der Fahrer den Touchscreen mit minimaler Hand- und Augenbewegung gut erreichen. Ein Touchscreen läßt sich auch durch Umprogrammieren sehrIn another preferred embodiment of the invention, the control element contains a touchscreen. A touchscreen, which is also known from computer technology, contains a sensor surface that is mounted above a display device, e.g. an LCD monitor. By touching certain positions on the touchscreen, a user can select elements displayed on the display device at this point. When selecting one of these elements, the corresponding vehicle function is advantageously carried out via a computing unit such as the one described above or a corresponding submenu with further selectable elements is displayed on the touchscreen. A touchscreen serves as a control element and a display at the same time and is easy to use. The touchscreen is preferably arranged in the area of the hub or a spoke of the steering wheel so that the driver can easily reach the touchscreen with minimal hand and eye movement. A touchscreen can also be very easily reprogrammed.
einfach mit weiteren Schaltfunktionen ausstatten, ohne daß mehr Schalter am Lenkrad unterzubringen sind.Easily equip it with additional switching functions without having to accommodate more switches on the steering wheel.
Bevorzugt wird vom Bedienelement ein Auslösesignal erzeugt, das an die Recheneinheit übertragen wird, wobei die Recheneinheit in Abhängigkeit vom Auslösesignal und von Positionsdaten die Ausführung einer Funktion veranlaßt. So lassen sich Fehlbedienungen vermeiden.Preferably, the control element generates a trigger signal which is transmitted to the computing unit, whereby the computing unit initiates the execution of a function depending on the trigger signal and position data. In this way, incorrect operation can be avoided.
Vorzugsweise werden auf der Anzeigevorrichtung auswählbare Symbole ' für Fahrzeugfunktionen dargestellt. Bei ihrer Auswahl wird die entsprechende Fahrzeugfunktion ausgelöst oder eine Änderung der Parameter dieser Funktion ermöglicht. Auf diese Weise kann eine graphische Menüsteuerung zur Verfügung gestellt werden, wobei jedes auswählbare Symbol entweder direkt eine Fahrzeugfunktion repräsentiert, z.B. das Ausschalten des Lichts, oder aber in eine tiefere Menüebene verzweigt, in der weitere auswählbare Symbole z.B. zur Einstellung von Parametern zur Verfügung stehen. Eine derartige Menüsteuerung ist überaus flexibel und läßt sich einfach an Veränderungen, z.B. den Einbau eines neuen Elements in das Fahrzeug oder den Einsatz in verschiedenen Fahrzeugtypen, anpassen.Preferably, selectable symbols for vehicle functions are shown on the display device. When selected, the corresponding vehicle function is triggered or a change to the parameters of this function is made possible. In this way, a graphic menu control can be provided, with each selectable symbol either directly representing a vehicle function, e.g. turning off the lights, or branching off to a deeper menu level in which further selectable symbols are available, e.g. for setting parameters. Such a menu control is extremely flexible and can be easily adapted to changes, e.g. the installation of a new element in the vehicle or use in different vehicle types.

ist am Lenkradkranz 16 oder an der Speiche 19 angeordnet. Das Bedienelement 20 enthält eine berührungsempfindliche Sensorfläche, die in diesem Ausführungsbeispiel als Touchpad 26 ausgebildet ist.is arranged on the steering wheel rim 16 or on the spoke 19. The operating element 20 contains a touch-sensitive sensor surface, which in this embodiment is designed as a touchpad 26.
Das Touchpad 26 ist mit einer Recheneinheit 36 (Fig. 3) und über diese mit einer Anzeigevorrichtung 22 verbunden, die ebenfalls Teil des elektronischen Systems sind. Die Anzeigevorrichtung 22 kann ein optisches Signal 24 auf die Windschutzscheibe 14 projizieren. Im weiteren wird dieses optische Signal 24 auch als Anzeige 24 bezeichnet.The touchpad 26 is connected to a computing unit 36 (Fig. 3) and via this to a display device 22, which are also part of the electronic system. The display device 22 can project an optical signal 24 onto the windshield 14. This optical signal 24 is also referred to as display 24 below.
Die restlichen genannten Bauteile im Fahrzeuginneren sind bekannt und für die dargestellte Erfindung nicht von Bedeutung, so daß sie hier nicht weiter beschrieben werden.The remaining components mentioned in the vehicle interior are known and not important for the invention presented, so that they will not be described further here.
Mit Hilfe der im Lenkrad angeordneten Sensorfläche und mit dem restlichen elektronischen System kann eine Steuerung von Fahrzeugfunktionen vorgenommen werden, wobei der Begriff "Steuerung" hier gleichbedeutend mit "Bedienung" und "Einstellung" verwendet wird.Vehicle functions can be controlled using the sensor surface in the steering wheel and the rest of the electronic system, whereby the term "control" is used here as synonymous with "operation" and "adjustment".
Die Funktion des elektronischen Systems wird im folgenden in Verbindung mit einem Touchpad genauer beschrieben (siehe auch Figur 3). Die Recheneinheit 36 erzeugt eine Benutzeroberfläche mit auswählbaren Symbolen 38, die über die Anzeigevorrichtung 22 als Anzeige 24 dargestellt werden. Den auswählbaren Symbolen 38 sind Fahrzeugfunktionen oder Untermenüs zugeordnet, wie dies von einer graphischen Benutzeroberfläche, z.B. WindowsTM> bekannt ist und hier nicht weiter erläutert werden soll.The function of the electronic system is described in more detail below in connection with a touchpad (see also Figure 3). The computing unit 36 generates a user interface with selectable symbols 38, which are shown as a display 24 via the display device 22. The selectable symbols 38 are assigned to vehicle functions or submenus, as is known from a graphical user interface, eg WindowsTM > and will not be explained further here.
Wenn der Fahrer das Touchpad 26 berührt, werden Richtungs- und/oder Ortsdaten an die Recheneinheit 36 übertragen und über diese auf der Anzeige 24 über die Bewegung eines beweglichen Elementes 40 (bevorzugt ein Mauszeiger) dargestellt. Durch Bewegung eines Fingers über das Touchpad 26 kann der Fahrer den Mauszeiger 40 auf dem gewünschten Symbol 38 plazieren. Eine weitere Betätigung des Touchpads, z.B. ein kurzes Antippen, liefert ein Auslösesignal an die Recheneinheit 36. Dadurch wird die Recheneinheit 36 dazu veranlaßt, die durch das Symbol 38 dargestellte Funktion auszuführen. Die Recheneinheit 36 ist dafür mit den die entsprechenden Fahrzeugfunktionen aufweisenden Elementen im Fahrzeug verbunden und überträgt auf bekanntem Weg Signa-When the driver touches the touchpad 26, direction and/or location data are transmitted to the computing unit 36 and shown on the display 24 via the movement of a movable element 40 (preferably a mouse pointer). By moving a finger over the touchpad 26, the driver can place the mouse pointer 40 on the desired symbol 38. Further actuation of the touchpad, e.g. a short tap, delivers a trigger signal to the computing unit 36. This causes the computing unit 36 to carry out the function represented by the symbol 38. The computing unit 36 is connected to the elements in the vehicle that have the corresponding vehicle functions and transmits signals in a known way.
Ie zur Ausführung der jeweiligen Funktion bzw. Parameter zur Einstellung der gewünschten Werte für eine Fahrzeugfunktion an die jeweiligen Elemente.Ie to execute the respective function or parameters to set the desired values for a vehicle function to the respective elements.
Figur 2 zeigt eine alternative Ausführangsform der Erfindung. Hier ist ein Touchscreen 30 im Bereich der Nabe 18 des Lenkrades 12 angeordnet. Der Touchscreen 30 kann, wie gezeigt, vom Fahrer aus gesehen vor einem Gassackmodul angeordnet sein, der Touchscreen könnte aber auch z.B. in einer Abdeckkappe des Gassackmoduls integriert sein. Der Touchscreen 30 selbst ist in einem Gehäuse 32 untergebracht, das auch eine Steuerplatine 34 enthält, die unter anderem Daten vom Touchscreen an eine Recheneinheit eines elektronischen Systems (wie in Figur 3 gezeigt) übertragen kann. Die Steuerplatine 34 kann auch als Teil der Recheneinheit ausgebildet sein. Der Touchscreen 30 dient gleichzeitig als Bedienelement, als Anzeigevorrichtung und als Anzeige.Figure 2 shows an alternative embodiment of the invention. Here, a touchscreen 30 is arranged in the area of the hub 18 of the steering wheel 12. The touchscreen 30 can, as shown, be arranged in front of a gas bag module as seen from the driver, but the touchscreen could also be integrated, for example, in a cover cap of the gas bag module. The touchscreen 30 itself is housed in a housing 32, which also contains a control board 34, which can, among other things, transmit data from the touchscreen to a computing unit of an electronic system (as shown in Figure 3). The control board 34 can also be designed as part of the computing unit. The touchscreen 30 serves simultaneously as a control element, as a display device and as a display.
Bei der Verwendung eines Touchscreens entfällt die Steuerung eines beweglichen Elementes, und der Fahrer erzeugt die Positionsdaten durch eine Berührung der Stelle der Sensorfläche, die direkt über dem auf der Anzeige dargestellten gewünschten Symbol liegt. Die entsprechenden Daten werden, wie oben beschrieben, von der Recheneinheit weiterverarbeitet. Als Auslösesignal dient bevorzugt eine wiederholte Berührung der gleichen Stelle.When using a touchscreen, there is no need to control a moving element and the driver generates the position data by touching the point on the sensor surface that is directly above the desired symbol shown on the display. The corresponding data is further processed by the computing unit as described above. Repeated touching of the same point is preferably used as a trigger signal.
In einer anderen, nicht dargestellten Ausführungsform der Erfindung ist vorgesehen, daß das Touchpad oder der Touchscreen auf einem beweglichen Schalter angeordnet ist, wobei der Schalter Teil des Bedienelements ist. Bevorzugt wird das Auslösesignal durch eine Betätigung des Schalters erzeugt. So erhält der Benutzer eine haptische Rückmeldung für die Ausführung einer Anweisung bzw. das Senden eines elektronischen Signals an die Recheneinheit. In Abhängigkeit von der gegebenen Anweisung können sich die auf dem Display dargestellten Funktionen oder Symbole ändern.In another embodiment of the invention (not shown), the touchpad or touchscreen is arranged on a movable switch, the switch being part of the control element. The trigger signal is preferably generated by actuating the switch. The user thus receives haptic feedback for executing an instruction or sending an electronic signal to the computing unit. The functions or symbols shown on the display can change depending on the instruction given.
In allen Ausführungsformen der Erfindung kann die Erzeugung eines Auslösesignals zusätzlich akustisch dargestellt werden, um dem Fahrer eine Rückmeldung zu geben, daß ein elektronisches Signal an die Recheneinheit gesendet wurde.In all embodiments of the invention, the generation of a trigger signal can additionally be represented acoustically in order to give the driver feedback that an electronic signal has been sent to the computing unit.
