Description

Verfahren und Vorrichtung zur Eingabe von Steuersignalen für Fahrzeugmodule Die Erfindung betrifft eine Vorrichtung zur Steuerung verschiedener Fahrzeugmodule, die zumindest einen Empfänger, eine Regel- und Steuerungseinheit und eine Messeinheit umfasst. Ausserdem betrifft die Erfindung ein Verfahren zur Steuerung verschiedener Fahrzeugmodule.Input method and device of control signals for Vehicle modules The invention relates to a device for control different vehicle modules, the at least one receiver, one Regulation and control unit and a measuring unit includes. Furthermore The invention relates to a method for controlling various Vehicle modules.

Bekannt ist als Fahrzeugmodul beispielsweise ein sogenannter "Tempomat", also eine Vorrichtung, mit deren Hilfe zur Entlastung des Fahrers auf Strecken wie Autobahnen, auf denen über längere Zeit mit gleichbleibender Geschwindigkeit gefahren werden kann, die Geschwindkeit einmal vom Fahrer eingestellt wird und dann mit Hilfe des Tempomaten gehalten wird. Dahinter steckt eine Geschwindkeitsregelanlage, die einen vorgegebenen Geschwindigkeitssollwert speichert und an eine Regel- und Steuerungseinheit weitergibt, die die Kraftstoffzufuhr des Fahrzeugs dann so einstellt, dass dieser Geschwindigkeitssollwert eingehalten wird. Dazu gehört auch eine Messeinheit, die den Unterschied zwischen dem Ist-Wert der Geschwindigkeit und dem Sollwert erkennt und an die Regelungseinheit weitergibt, die dann die Kraftstoffzufuhr entsprechend regelt, damit der Ist-Wert der Geschwindigkeit dem Sollwert entspricht.Is known as a vehicle module, for example a so-called "cruise control", ie a device with their help to relieve the driver on routes such as motorways, on those over longer time can be driven at a constant speed, the speed is set once by the driver and then held using the cruise control becomes. Behind it is a speed control system, some stores the specified speed setpoint and sends it to a control and passes control unit that the fuel supply of the vehicle then set so that this speed setpoint is maintained becomes. That is part of it also a measurement unit that shows the difference between the actual value recognizes the speed and the setpoint and sends it to the control unit passes on, which then regulates the fuel supply accordingly, so that The actual value of the speed corresponds to the setpoint.

Die Geschwindigkeitssollwerte können vorgegeben werden, gespeichert sein, aktiviert und/oder gelöscht werden. Dazu dienen beispielsweise Bediehnhebel ( EP 441 961 A1 ), Kippschalter ( DE 17 38 660 U1 ) und/oder Drucksensoren am Lenkrad ( DE 198 02 249.2 ). Zur Änderung der Geschwindigkeit gibt der Fahrer entweder einen neuen Sollwert ein oder er stellt das System um auf "manuelle Eingabe", das heisst in der Regel, dass er wieder selbst Gas gibt, wodurch der Tempomat automatisch ausser Kraft gesetzt wird.The speed setpoints can be specified, saved, activated and / or deleted. Serving levers (e.g. EP 441 961 A1 ), Toggle switch ( DE 17 38 660 U1 ) and / or pressure sensors on the steering wheel ( DE 198 02 249.2 ). To change the speed, the driver either enters a new setpoint or he switches the system to "manual entry", which usually means that he accelerates again, which automatically overrides the cruise control.

Die Eingabe der Sollwerte für diese und andere Module eines Fahrzeugs erfolgt in der Regel durch direkte numerische Eingabe oder durch Druck, Drehen oder sonstwie mechanisch. Dies ist vergleichsweise umständlich und/oder ungenau.Entering the setpoints for this and other modules of a vehicle are usually done by direct numerical entry or by pressure, turning or otherwise mechanically. This is comparatively cumbersome and / or inaccurate.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Eingabe eines Sollwertes für zumindest ein Fahrzeugmodul zu schaffen, bei dem die Eingabe des Sollwertes schnell, bequem und exakt erfolgen kann.Object of the present invention is therefore a device for entering a setpoint for at least to create a vehicle module in which the input of the setpoint can be done quickly, conveniently and precisely.

Gegenstand der Erfindung ist eine Vorrichtung zur Eingabe von Steuersignalen für die Beeinflussung zumindest einer Regelungs- und Steuereinheit eines Fahrzeugs, beispielsweise einer Geschwindigkeitsregelanlage oder eines Tempomats, die zumindest einen Empfänger, eine Regel- und Steuerungseinheit und eine Messeinheit umfasst, wobei der Empfänger ein Mikrophon hat. Ausserdem ist Gegenstand der Erfindung ein Verfahren zur Eingabe von Steuersignalen für die Beeinflussung zumindest einer Regelungs- und Steuereinheit eines Fahrzeugs, wobei die Steuersignale zumindest zum Teil akustisch gegeben werden.The invention relates to a At least device for inputting control signals for influencing a regulation and control unit of a vehicle, for example a cruise control system or a cruise control, at least a recipient, comprises a regulating and control unit and a measuring unit, wherein the recipient has a microphone. The invention also relates to a method for entering control signals for influencing at least one regulating and control unit of a vehicle, wherein the control signals are given at least in part acoustically.

Mit Hilfe der Erfindung ist es möglich, durch einfaches Aussprechen, beispielsweise einer Geschwindigkeit, einen Tempomaten zu programmieren und das Fahrzeug schnell, bequem und automatisch auf eine bestimmte, vorgegebene Geschwindigkeit genau einzustellen.With the help of the invention it is possible by simple Say, for example a speed, a cruise control to program and the vehicle quickly, conveniently and automatically to set a certain, predetermined speed exactly.

Als "Mikrophon" wird hier jedes Bauteil bezeichnet, durch das ein akustisch ausgegebenes Signal empfangen und in einen elektrischen oder elektronischen, insbesondere digital auslesbaren Impuls umgewandelt werden kann.Each component is referred to here as a "microphone", through which an acoustically output signal is received and into a electrical or electronic, in particular digitally readable Impulse can be converted.

Als "Modul" wird hier jedes selbständig motorisierte oder betreibbare Teil eines Fahrzeugs, also der Tempomat für den Motor, die Klimaanlage oder Heizung, die Scheibenwischer, der Radio, die elektrischen Fensterheber, das Verdeck des Cabriolets, die Innenbeleuchtung, einfach alle Regelungs- und Steuerungseinheiten, die im Fahrzeug integriert sind.As a "module", each is independently motorized or operable part of a vehicle, i.e. the cruise control for the engine, the air conditioning or heating, the wipers, the radio, the electric windows, the convertible top, interior lighting, simply all regulation and control units in the vehicle are integrated.

Der Empfänger kann neben dem Mikrophon noch beliebige andere Empfangsvorrichtungen umfassen, durch die er entweder an die gleiche Regel- und Steuereinheit Informationen weitergibt oder an andere Regel- und Steuereinheiten wie z. B. die der Klimaanlage, des Ventilators, des Scheibenwischers und andere. Das heisst, die Regelungs- und Steuereinheit kann beispielsweise akustisch und, alternativ oder ergänzend dazu, über Druck eingestellt werden, je nachdem, wie es für den Fahrer komfortabler ist und es kann, je nach Angabe, in einem Satz eine Temperatur im Innenraum des Fahrzeugs und eine bestimmte Geschwindigkeit des Fahrzeugs eingestellt werden.In addition to the microphone, the receiver can still include any other receiving devices through which it either forwards information to the same regulating and control unit or to other regulation and control units such. B. the air conditioning, of the fan, the wiper and others. That is, the Regulation and control unit can for example acoustically and, alternatively or additionally to about Pressure can be adjusted depending on how comfortable it is for the driver and Depending on the specification, a temperature in the interior can be set in one sentence of the vehicle and a certain speed of the vehicle become.

Durch den Empfänger erreicht im Betrieb jedenfalls ein elektrisch und/oder elektronisch übertragbares Signal die betroffene Regelungs- und Steuereinheit, die daraus beispielsweise ihren Geschwindigkeitssollwert entnimmt. Gleichzeitig wird die Messvorrichtung aktiviert, so dass der Ist-Wert – um bei dem Beispiel zu bleiben – der Geschwindigkeit ermittelt und der Regelungs- und Steuereinheit zum Vergleich mitgeteilt wird. Daraus errechnet die Regelungs- und Steuereinheit ein Delta, das wiederum als Grundlage für die Einstellung der Kraftstoffzufuhr und/oder die erforderliche Bremskraft dient.In any case, achieved by the receiver in operation an electrically and / or electronically transferable signal the affected Regulation and control unit, which, for example, gives your speed setpoint extracts. At the same time the measuring device is activated so that the actual value - um at to stick to the example - the Speed determined and the regulation and control unit for comparison is communicated. The regulation and control unit calculates from this a delta, which in turn is the basis for adjusting the fuel supply and / or the required braking force is used.

Für andere Module, wie die Klimaanlage oder Heizung, den Scheibenwischermotor, die Lüftung, die Fenster etc. ist das oben beschriebene Beispiel einfach übertragbar.For other modules, such as air conditioning or heating, the wiper motor, the ventilation, the windows, etc., the example described above is easily transferable.
