Description
Anordnung zur Erzeugung von Vibrationen zur Fahrerinformation in Kraftfahrzeugen nach dem Oberbegriff des Anspruch 1.Arrangement for generating vibrations for Driver information in motor vehicles according to the preamble of the claim 1.
In einem Kraftfahrzeug ist es in unterschiedlichen Situationen wünschenswert, die Aufmerksamkeit des Fahrers in besonderer Weise anzuregen. So ist es bekannt, den Fahrer darauf aufmerksam zu machen, daß er sich in einer Gefahrensituation befindet, z. B. durch einen Sekundenschlaf. Solche Situationen können mit Sensoren, z.B. mit optischen oder Bewegungssensoren, erfaßt werden und durch diese wird ein akustisches, optisches oder Vibrationssignal ausgelöst.In a motor vehicle it is in different situations desirable to stimulate the driver's attention in a special way. So is It is known to make the driver aware that he is is in a dangerous situation, e.g. B. by a nap. Such situations can with sensors, e.g. with optical or motion sensors and this triggers an acoustic, optical or vibration signal.

Für die Erzeugung von Vibrationen am Lenkrad ist es aus der Praxis bekannt, Elektromotoren an das Lenkradskelett anzukoppeln, die unwuchtige Massen bewegen und dadurch Schwingungen erzeugen. Der Nachteil dieser Anordnung besteht darin, daß diese Art der Schwingungserzeugung aufwendig und mit Geräuschentwicklung verbunden ist, was insbesondere bei einer Plazierung am Lenkrad störend ist. Weiterhin können Probleme durch die begrenzte Lebensdauer der Motoren eintreten.For the generation of vibrations on the steering wheel is known from practice, Coupling electric motors to the steering wheel skeleton, the unbalanced masses move and thereby generate vibrations. The disadvantage of this arrangement is that this Type of vibration generation complex and with noise is connected, which is particularly troublesome when placed on the steering wheel. Can continue Problems arise due to the limited life of the motors.
Der Erfindung liegt die Aufgabe zugrunde, Vibrationen für die Fahrerinformation einfacher und zumindest nahezu geräuschlos zu erzeugen.The invention is based, vibration for the Driver information easier and at least almost noiseless to create.
Erfindungsgemäß wird das gemäß den Merkmalen des Anspruchs 1 erreicht.According to the invention, this is according to the features of claim 1 achieved.
Bei einer Anordnung zur Erzeugung von Vibrationen zur Fahrerinformation in Kraftfahrzeugen an mindestens einem vom Fahrer eines Kraftfahrzeuges kontaktierten oder einsehbaren Kraftfahrzeugteil ist erfindungsgemäß zur Erzeugung von Vibrationen mindestens ein Piezoelement vorgesehen, an das im Falle des Auftretens eines an den Fahrer zu übermittelnden Ereignisses automatisch eine elektrische Wechselspannung anlegbar ist.With an arrangement for generation of vibrations for driver information in motor vehicles at least a contact or viewable by the driver of a motor vehicle Motor vehicle part according to the invention for generating vibrations at least a piezo element is provided to which in the event of the occurrence of a to be sent to the driver Event, an electrical AC voltage can be automatically applied is.
Wird auf ein Piezoelement eine Kraft mit einer gewissen Geschwindigkeit ausgeübt, so entsteht bekanntlich im Inneren der Struktur eine Ladungstrennung, die an den Elektroden des Piezoelements eine Spannung erzeugt. Die Spannung ist dem Druck auf das Element proportional. Umgekehrt entsteht eine Bewegung, wenn an das Piezomaterial eine elektrische Spannung angelegt wird.Becomes a force on a piezo element exercised at a certain speed, as is well known inside the structure there is a charge separation on the electrodes of the piezo element generates a voltage. The tension is on the pressure the element proportional. Conversely, a movement arises when an electrical voltage is applied to the piezo material.
Diese Anordnung zur Erzeugung von Vibrationen mittels Piezoelementen ist wesentlich einfacher, kleiner und weniger störanfällig als eine Anordnung mit Motoren und unwuchtigen Massen.This arrangement for generating Vibrations using piezo elements is much easier, smaller and less prone to failure than an arrangement with motors and unbalanced masses.
Zur Erzielung einer ausreichenden Vibration des Kraftfahrzeugteils ist es zweckmäßig, daß das Piezoelement fest mit dem Kraftfahrzeugteil verbunden ist. Das kann zum Beispiel dadurch erfolgen, daß das Piezoelement durch Kleben, Klemmen und/oder Umspritzen mit dem Kraftfahrzeugteil verbunden ist.To achieve sufficient Vibration of the motor vehicle part, it is appropriate that the piezo element firmly with the motor vehicle part is connected. This can be done, for example done that the Piezo element by gluing, clamping and / or extrusion coating with the motor vehicle part connected is.
Für die Anbringung der Piezoelemente sind mehrere Kraftfahrzeugteile geeignet. Ein bevorzugter Ort der Anbringung von Piezoelementen ist das Lenkrad und hier insbesondere das Lenkradskelett, da der Fahrer das Lenkrad ständig handhaben muß. Vorzugsweise ist das Piezoelement im Bereich des Lenkradkranzes oder im Bereich der Speichen des Lenkrades angeordnet.For the attachment of the piezo elements are several motor vehicle parts suitable. A preferred location for attaching piezo elements is the steering wheel and in particular the steering wheel skeleton, because the Driver's steering wheel constantly must handle. Preferably is the piezo element in the area of the steering wheel rim or in the area the spokes of the steering wheel arranged.
Bei einem Lenkrad mit Airbag und einer Floating-Horn-Anordnung, wie sie heute vielfach verwendet wird, kann das Piezoelement auch mit der Airbaganordnung verbunden sein. Damit wird eine gezielte Vibration des Airbagmoduls erzielt, wobei das Lenkrad kaum vibriert. Dabei kann das Piezoelement sowohl mit dem Airbagträger, mit dem Airbaggehäuse oder mit einer Kontaktbrücke verbunden sein.With a steering wheel with airbag and a floating horn arrangement, as is often used today the piezo element can also be connected to the airbag arrangement his. In this way, a targeted vibration of the airbag module is achieved the steering wheel hardly vibrates. The piezo element can both with the airbag carrier, with the airbag housing or with a contact bridge be connected.
Ein weiterer bevorzugter Ort für das Anbringen von Piezoelementen kann der Bereich des Fahrzeugsitzes sein, da der Fahrer mit diesem ebenfalls ständigen Kontakt hat.Another preferred place for attachment Piezo elements can be the area of the vehicle seat, because the driver is in constant contact with them.
Dabei kann mindestens ein Piezoelement sowohl im Bereich der Sitzfläche als auch im Bereich der Rückenlehne angeordnet sein.At least one piezo element can be both in the area of the seat as well as in the area of the backrest be arranged.
Weiterhin kann das Piezoelement auch an mindestens einem Pedal des Kraftfahrzeuges, insbesondere am Gaspedal angeordnet sein.Furthermore, the piezo element can also on at least one pedal of the motor vehicle, in particular on the accelerator pedal be arranged.
Um eine sichere Information des Fahrers zu erzielen, ist es weiterhin zweckmäßig, daß eine Vielzahl von Piezoelementen an unterschiedlichen Kraftfahrzeugteilen angeordnet ist.To provide the driver with safe information To achieve, it is also appropriate that a variety of piezo elements is arranged on different motor vehicle parts.
Die Erfindung soll in Ausführungsbeispielen anhand von Zeichnungen erläutert werden. Es zeigen:The invention is to be described in exemplary embodiments explained by drawings become. Show it:
