Description

Lenkrad für ein Kraftfahrzeug  Steering wheel for a motor vehicle
Die Erfindung betrifft ein Lenkrad für ein Kraftfahrzeug. Kraftfahrzeuge sind üblicherweise mit Fahrtrichtungsanzeigern (nachfolgend „Blinkern") ausgestattet sowie mit einer Warnblinkanlage. Um die Blinker zu betätigen, ist meist in der Nähe des Lenkrades ein Hebel angeordnet, der vom Fahrer betätigt werden kann. Um die Warnblinkanlage ein- oder auszuschalten, ist meist eine Taste vorgesehen, die an einer mehr oder weniger intuitiv auffindbaren Stelle im Cockpit des Fahrzeugs oder zwischen den Vordersitzen angeordnet ist. The invention relates to a steering wheel for a motor vehicle. Motor vehicles are usually equipped with direction indicators (hereafter "indicators") and with a hazard warning device.To operate the indicators, a lever is usually located near the steering wheel that can be actuated by the driver.To turn the hazard warning lights on or off is usually provided a button that is located at a more or less intuitive location in the cockpit of the vehicle or between the front seats.
Sowohl um den Blinker als auch die Warnblinkanlage zu betätigen, muss der Fahrer mindestens einen Teil einer Hand vom Lenkrad wegbewegen, wenn nicht gar die ganze Hand. Insbesondere beim Einschalten der Warnblinkanlage ist dies für die Verkehrssicherheit nicht unbedingt förderlich. Zum einen muss die Warnblinkanlage oft bei Gefahrensituationen eingeschaltet werden, beispielsweise wenn der Fahrer das Ende eines Staus vor sich bemerkt und stark bremsen muss, und zum anderen wird die Warnblinkanlage meist so selten eingeschaltet, dass der Fahrer die entsprechende Taste üblicherweise nicht intuitiv findet, sondern etwas suchen muss - möglicherweise in einer Situation, in der der Blick auf die Fahrbahn sehr wichtig ist. Both to operate the turn signal and the hazard warning lights, the driver must move at least a portion of one hand away from the steering wheel, if not the whole hand. In particular, when switching on the hazard warning lights this is not necessarily conducive to traffic safety. On the one hand, the hazard warning lights often have to be switched on in dangerous situations, for example when the driver has noticed the end of a traffic jam in front of him and has to brake hard, and secondly the hazard warning lights are usually switched on so rarely that the driver usually does not find the key intuitive, but instead something has to look for - possibly in a situation in which the view of the road is very important.
Die Aufgabe der Erfindung besteht darin, die Bedienung des Blinkers und der Warnanlage zu vereinfachen. The object of the invention is to simplify the operation of the turn signal and the warning system.
Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Lenkrad mit einer Nabe, mindestens einer Speiche und einem Lenkradkranz vorgesehen, dadurch gekennzeichnet, dass an der Nabe mindestens zwei berührungsempfindliche Sensorbereiche vorgesehen sind, wobei den Sensorbereichen eine Auswerteelektronik zugeordnet ist, die vordefinierten Wisch-Gesten auf den Sensorbereichen erkennen kann. Mittels der Sensorbereiche kann der Fahrer den Blinker ein- oder ausschalten oder auch die Warnblinkanlage ein- oder ausschalten, ohne die Hände vom Lenkrad nehme zu müssen; da die Sensorbereiche an der Lenkradnabe angeordnet sind, können sie beispielsweise von den Daumen erreicht werden, ohne dass das Lenkrad losgelassen werden muss. Außerdem befinden sich die Sensorbereiche (zumindest in den allermeisten Fahrsituationen) in einer einzigen, dem Fahrer bekannten Position, so dass er intuitiv und ohne Suchen die Sensorbereiche findet. To achieve this object, a steering wheel with a hub, at least one spoke and a steering wheel rim is provided according to the invention, characterized in that at least two touch-sensitive sensor areas are provided on the hub, wherein the sensor areas associated with an evaluation, the predefined wiping gestures on the sensor areas can recognize. By means of the sensor areas, the driver can turn the turn signal on or off or switch the hazard warning lights on or off without having to take your hands off the steering wheel; since the sensor areas are arranged on the steering wheel hub, they can be reached, for example, by the thumbs without having to let go of the steering wheel. In addition, the sensor areas (at least in the vast majority of driving situations) are in a single position known to the driver, so that he finds the sensor areas intuitively and without searching.
Vorzugsweise befinden sich die Sensorbereiche auf der 10-Uhr-Position und der 2-Uhr-Position des Lenkrades, so dass sie bei der üblichen Position der Hände am Lenkrad problemlos mit den Daumen erreicht werden können. Preferably, the sensor areas are at the 10 o'clock position and the 2 o'clock position of the steering wheel so that they can be easily reached with the thumbs at the usual position of the hands on the steering wheel.
Gemäß einer Ausgestaltung der Erfindung ist vorgesehen, dass die Sensorbereiche durch getrennte Sensorelemente gebildet sind, so dass sie gut in bekannte Lenkräder integriert werden können, ohne deren Design zu stören. According to one embodiment of the invention, it is provided that the sensor areas are formed by separate sensor elements, so that they can be well integrated into known steering wheels without disturbing their design.
Gemäß einer alternativen Ausgestaltung ist vorgesehen, dass die Sensorbereiche jeweils Teil eines durchgehenden Sensorelements sind. Dieses kann sich entlang des gesamten oberen Randes der Lenkradnabe erstrecken und aufgrund seiner großen Fläche entweder ein Betätigen des Blinkers und der Warnblinkanlage an unterschiedlichen Positionen erlauben, oder es können zusätzliche Funktionen in die Sensorbereiche integriert werden, insbesondere in den Abschnitten nahe der 12-Uhr-Position. According to an alternative embodiment, it is provided that the sensor regions are each part of a continuous sensor element. This may extend along the entire upper edge of the steering wheel hub and, due to its large area, either permit actuation of the turn signal and the hazard warning lights at different positions, or additional functions may be integrated into the sensor areas, particularly in the sections near the 12 o'clock position. Position.
Um den Blinker ein- oder auszuschalten, kann in der Auswerteelektronik eine Wisch-Geste auf dem Sensorbereich in einer Richtung hinterlegt sein. Grundsätzlich können unterschiedliche Wisch-Gesten verwendet werden, um den Blinker ein- und auszuschalten. Beispielsweise kann, um den rechten Blinker einzuschalten, auf dem linken Sensorbereich im Uhrzeigersinn gewischt werden, also nach rechts. Um den rechten Blinker wieder auszuschalten, kann eine Wisch- Geste in entgegengesetzter Richtung verwendet werden. Diese kann, muss aber nicht notwendigerweise auf demselben Sensorbereich erfolgen, der zum Einschalten verwendet wurde. Es ist auch denkbar, dass, wenn ein Blinker eingeschaltet ist, eine beliebige Wisch-Geste dahingehend interpretiert ist, dass der Blinker wieder ausgeschaltet werden soll. Es ist auch denkbar, dass dem Fahrer die Möglichkeit gegeben wird, die von ihm bevorzugten oder für intuitiv gehaltenen Wisch-Gesten individuell zu programmieren. So ist denkbar, dass ein Fahrer den rechten Blinker durch eine Wisch-Geste auf dem rechten Sensorbereich einschalten möchte. Um die Warnblinkanlage ein- bzw. auszuschalten, können in der Auswerteelektronik zwei gleichzeitige Wisch-Gesten auf unterschiedlichen Sensorbereichen in entgegengesetzten Richtungen als Signal hinterlegt sein. Hierdurch können diese Gesten sehr einfach von den Signalen zum Ein- bzw. Ausschalten des Blinkers unterschieden werden. Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass jeder Sensorbereich in mindestens drei Kontrollabschnitte unterteilt ist. Die Auswerteelektronik überprüft dabei, ob nach einer Aktivierung eines ersten Sensorabschnittes auch ein zweiter und ein dritter Sensorabschnitt in genau dieser Reihenfolge aktiviert werden. Dies ermöglicht es, eine versehentliche Berührung des Sensorbereichs von einer intendierten Wisch-Geste zu unterscheiden. To turn the turn signal on or off, a wiping gesture on the sensor area can be stored in one direction in the transmitter. In principle, different wiping gestures can be used to turn the turn signal on and off. For example, to turn on the right turn signal, you can swipe clockwise in the left sensor area, ie to the right. To turn the right turn signal off again, a swipe gesture in the opposite direction can be used. This may or may not necessarily be on the same sensor area used for power up. It is also conceivable that when a turn signal is turned on, any swipe gesture is interpreted to the effect that the turn signal is to be switched off again. It is also conceivable that the driver is given the opportunity to individually program his preferred or intuitively held wiping gestures. So it is conceivable that a driver wants to turn on the right turn signal by a swipe gesture on the right sensor area. In order to switch the hazard warning lights on or off, two simultaneous wiping gestures on different sensor areas in opposite directions can be stored in the evaluation electronics as a signal. As a result, these gestures can be easily distinguished from the signals for turning on and off the turn signal. According to one embodiment of the invention, it is provided that each sensor area is subdivided into at least three control sections. The transmitter checks whether, after activation of a first sensor section, a second and a third sensor section are activated in exactly this order. This makes it possible to distinguish an inadvertent contact of the sensor area from an intended swipe gesture.
Grundsätzlich gibt es verschiedene Möglichkeiten, die Sensorbereiche technisch zu realisieren. Beispielsweise können die Sensorbereiche durch kapazitive Sensoren gebildet sein, wie sie als„touch screen" bekannt sind. Es sich auch möglich, die Sensorbereiche durch druckempfindliche Sensoren auszubilden. Dies hat den Vorteil, dass die Wisch-Gesten auch dann erkannt werden können, wenn der Fahrer Handschuhe trägt. Basically, there are various ways to realize the sensor areas technically. For example, the sensor areas may be formed by capacitive sensors, as known as "touch screens." It is also possible to form the sensor areas by means of pressure-sensitive sensors, which has the advantage that the wiping gestures can be recognized even when the sensor is touched Driver wearing gloves.
Gemäß einer Ausführungsform ist vorgesehen, dass in die Sensorbereiche Lichtquellen integriert sind. Diese können dem Fahrer anzeigen, dass er den Blinker oder die Warnblinkanlage aktiviert hat, beispielsweise durch Blinken nur auf einem Sensorbereich, wenn auf der entsprechenden Seite der Blinker eingeschaltet ist, oder durch Blinken auf beiden Sensorbereichen gleichzeitig, wenn die Warnblinkanlage eingeschaltet ist. Der Fahrer erhält somit eine unmittelbare Rückmeldung, dass seine Wisch-Geste umgesetzt wurde. According to one embodiment, it is provided that light sources are integrated into the sensor regions. These may indicate to the driver that he has activated the turn signal or the hazard warning lights, for example by flashing only on one sensor area when the turn signal is switched on on the corresponding side, or by flashing on both sensor areas simultaneously when the hazard warning lights are switched on. The driver thus receives immediate feedback that his wiping gesture has been implemented.
Es ist auch denkbar, in die Sensorbereiche einen Aktor zu integrieren, der durch Vibrieren ein haptische Rückmeldung (vergleichbar dem Schaltgefühl bei der Betätigung eines mechanischen Schalters) gibt, dass der Blinker oder die Warnblinkanlage ein- oder ausgeschaltet wurde. Die Erfindung wird nachfolgend anhand einer Ausführungsform beschrieben, die in den beigefügten Zeichnungen dargestellt ist. In den Zeichnungen zeigen: It is also conceivable to integrate into the sensor areas an actuator, which gives a haptic feedback (comparable to the shift feeling when operating a mechanical switch) by vibrating that the turn signal or the hazard warning lights has been switched on or off. The invention will be described below with reference to an embodiment shown in the accompanying drawings. In the drawings show:

Figur 6 ein fünftes Beispiel einer Wisch-Geste, mit der eine fünfte Funktion geschaltet werden kann; und Figure 6 shows a fifth example of a swipe gesture with which a fifth function can be switched; and
Figur 7 ein sechstes Beispiel einer Wisch-Geste, mit der eine sechste Funktion geschaltet werden kann. FIG. 7 shows a sixth example of a swipe gesture with which a sixth function can be switched.
In Figur 1 ist ein Lenkrad 10 zu sehen, das eine Nabe 12, einen Lenkradkranz 14 sowie mehrere Speichen 16 aufweist, die den Lenkradkranz 14 mit der Nabe 12 verbinden. In Figure 1, a steering wheel 10 can be seen, which has a hub 12, a steering wheel rim 14 and a plurality of spokes 16 which connect the steering wheel rim 14 with the hub 12.
Die Nabe 12 ist mit zwei berührungsempfindlichen Sensorbereichen 20 versehen, die sich entlang des Randes der Nabe 12 erstrecken, der bei Geradeausfahrt des Fahrzeugs oben liegt. The hub 12 is provided with two touch-sensitive sensor areas 20 extending along the edge of the hub 12 which is up when the vehicle is traveling straight ahead.
Die beiden Sensorbereiche 20 sind hier als räumlich getrennte Sensorelemente ausgeführt. The two sensor regions 20 are designed here as spatially separated sensor elements.
Sie sind so in die Nabe 12 des Lenkrades integriert, dass sie sich optisch und auch haptisch gut einfügen. Beispielsweise können sie im Wesentlichen bündig mit der Oberfläche der Nabe 12 des Lenkrades 10 ausgeführt sein. They are integrated into the hub 12 of the steering wheel so that they blend in optically and haptically well. For example, they may be substantially flush with the surface of the hub 12 of the steering wheel 10.
Die Position der beiden Sensorbereiche 20 ist so gewählt, dass das in Figur 1 links angeordnete Sensorelement 20 sich auf der „10-Uhr-Position" befindet, während sich der rechte Sensorbereich auf der„2-Uhr-Position" befindet. Gemäß einer abweichenden Ausführungsform ist vorgesehen, dass die beiden Sensorbereiche 20 Teil eines einzigen, durchgehenden Sensorelements sind, das sich entlang des gesamten oberen Randes der Nabe 12 des Lenkrades 10 erstreckt, also auch über die 12-Uhr-Position. Die beiden Sensorbereiche können durch kapazitive Sensoren gebildet sein, also ähnlich wie ein berührungsempfindlicher Bildschirm (Touchscreen) arbeiten. Alternativ ist auch möglich, dass die Sensorbereiche druckempfindlich sind. The position of the two sensor regions 20 is selected such that the sensor element 20 arranged on the left in FIG. 1 is in the "10 o'clock position", while the right-hand sensor region is in the "2 o'clock position". According to a different embodiment, it is provided that the two sensor regions 20 are part of a single, continuous sensor element which extends along the entire upper edge of the hub 12 of the steering wheel 10, that is to say also over the 12 o'clock position. The two sensor areas can be formed by capacitive sensors, that is similar to a touch-sensitive screen (touch screen) work. Alternatively, it is also possible that the sensor areas are sensitive to pressure.
Den beiden Sensorbereichen 20 ist eine hier nicht weiter dargestellte Auswerteelektronik zugeordnet, die in der Lage ist zu erkennen, ob ein Bediener mindestens einen der Sensorbereiche verwendet, um eine Bedieneingabe zu machen. Bei der Bedieneingabe handelt es sich insbesondere um eine Wisch- Geste, die auf einem der Sensorbereiche 20 oder gleichzeitig auf beiden Sensorbereichen 20 durchgeführt wird. The two sensor regions 20 are associated with an evaluation electronics not shown here, which is able to detect whether an operator uses at least one of the sensor areas to make an operator input. The operator input is, in particular, a swipe gesture which is carried out on one of the sensor regions 20 or simultaneously on both sensor regions 20.
In der Auswerteelektronik können unterschiedliche Wisch-Gesten hinterlegt sein. Dort ist auch hinterlegt, dass eine Wisch-Geste über eine vorbestimmte Länge durchgeführt werden muss, damit sie von einer unbeabsichtigten Berührung eines der Sensorbereiche 20 unterschieden werden kann. Different wiping gestures can be stored in the transmitter. There is also deposited, that a wiping gesture must be performed over a predetermined length, so that it can be distinguished from an accidental contact of one of the sensor regions 20.
Es kann auch vorgesehen sein, dass die Sensorbereiche virtuell in verschiedene Kontrollabschnitte unterteilt sind, beispielsweise drei Kontrollabschnitte, und dass eine Berührung der Sensorbereiche 20 nur dann als Wisch-Geste interpretiert wird, wenn eine Berührung der Sensorbereiche nacheinander in beispielsweise drei der Kontrollabschnitte erkannt wird. It can also be provided that the sensor areas are virtually subdivided into different control sections, for example three control sections, and that a touch of the sensor areas 20 is interpreted as a swipe gesture only if a touch of the sensor areas is recognized successively in, for example, three of the control sections.
Mit den Wisch-Gesten auf den Sensorbereichen 20 können insbesondere die Blinker des Fahrzeugs ein- und ausgeschaltet werden sowie die Warnblinkanlage ein- und ausgeschaltet werden. In particular, the turn signals of the vehicle can be switched on and off and the hazard warning lights can be switched on and off with the swipe gestures on the sensor areas 20.
In den Figuren 2a bis 5b sind verschiedene Wisch-Gesten dargestellt, die zum Ein- bzw. Ausschalten des Blinkers verwendet werden können. Dabei sind in den Figuren 2a, 3a, 4a und 5a der linke Sensorbereich 20 der Nabe 12 dargestellt, während in den Figuren 2b, 3b, 4b und 5b der rechte Sensorbereich 20 der Lenkradnabe gezeigt ist. Um den rechten Blinker einzuschalten, kann beispielsweise eine Wisch-Geste im Uhrzeigersinn auf dem linken Sensorbereich (Figur 2a) oder dem rechten Sensorbereich (Figur 2b) verwendet werden. Zum Ausschalten des rechten Blinkers kann dann eine entgegengesetzte Wisch-Geste verwendet werden (siehe die Figuren 3a und 3b). FIGS. 2a to 5b show various wiping gestures that can be used to turn the turn signal on and off. 2a, 3a, 4a and 5a, the left sensor region 20 of the hub 12 are shown, while in the figures 2b, 3b, 4b and 5b, the right sensor portion 20 of the steering wheel hub is shown. To turn on the right turn signal, for example, a wiping gesture in the clockwise direction on the left sensor area (Figure 2a) or the right sensor area (Figure 2b) can be used. To turn off the right turn signal then an opposite swipe gesture can be used (see Figures 3a and 3b).
Die entgegengesetzten Wisch-Gesten können zum Einschalten des linken Blinkers (Figuren 4a und 4b) bzw. zum Ausschalten (Figuren 5a und 5b) verwendet werden. The opposite swipe gestures can be used to turn on the left turn signal (FIGS. 4a and 4b) and turn it off (FIGS. 5a and 5b).
Grundsätzlich ist denkbar, dass die Auswerteelektronik vom Fahrer des Fahrzeugs individuell programmiert werden kann, also dass der Fahrer hinterlegen kann, welche Wisch-Geste zu welcher Betätigung des Blinkers führt. In principle, it is conceivable that the transmitter can be individually programmed by the driver of the vehicle, so that the driver can deposit which wiping gesture leads to which actuation of the turn signal.
Um die Warnblinkanlage ein- bzw. auszuschalten, kann in der Auswerteelektronik hinterlegt werden, dass entgegengesetzte Wisch-Gesten auf beiden Sensorbereichen 20 gleichzeitig erfolgen müssen. Beispielsweise kann mit den in Figur 6 dargestellten Wisch-Gesten, die jeweils von innen nach außen gerichtet sind, die Warnblinkanlage eingeschaltet werden, während mit den in Figur 7 dargestellten Wisch-Gesten die Warnblinkanlage wieder ausgeschaltet wird. In order to switch the hazard warning lights on or off, it can be deposited in the evaluation electronics that opposite wiping gestures on both sensor areas 20 must take place simultaneously. For example, with the wiping gestures shown in FIG. 6, which are respectively directed from the inside to the outside, the hazard warning lights are switched on, while the hazard warning lights are switched off again with the wiping gestures shown in FIG.
Der besondere Vorteil besteht darin, dass die Wisch-Gesten mit den Daumen durchgeführt werden können, ohne dass der Fahrer hierfür die Hände vom Lenkrad nehmen muss. Es ist auch nicht nötig, die zum Ein- und Ausschalten der Warnblinkanlage üblicherweise im Stand der Technik vorgesehene Taste suchen zu müssen. The particular advantage is that the swipe gestures can be performed with the thumbs, without the driver having to take his hands off the steering wheel. It is also not necessary to search for the switching on and off of the hazard warning lights usually provided in the prior art button.
