Abstract

Ecological tachometer has a display unit for displaying vehicle and engine speed with both vehicle speed (1) and engine speed (2) scales. The graduations of the engine speed scale vary according to the selected gear.

Description

Gegenstand des Patents ist die integrierte optische Anzeige der Motordrehzahl und des jeweils geschalteten Gangs in Kraftfahrzeugtachometern, wobei die Skalen für die Geschwindigkeit und die Motordrehzahl entsprechend dem jeweils geschalteten Gang in direkter Proportionalität so dargestellt sind, dass die sich entsprechenden Skalenwerte unter einander stehen und die Messwerte mit einer gemeinsamen Markierung angezeigt werden.The subject of the patent is the integrated optical Displays the engine speed and the gear selected in Motor vehicle tachometers, the scales for the speed and the Engine speed in direct accordance with the gear selected proportionality are shown in such a way that the corresponding scale values below stand with each other and the measured values with a common marking are displayed.

Die Motordrehzahl wird bisher mit einem separaten Anzeigegerät neben dem Tachometer angezeigt. Eine Ganganzeige fehlt in der Regel.The engine speed is so far with a separate display device displayed next to the speedometer. A gear indicator is usually missing.

Diese Lösung hat den Nachteil, dass hierfür ein eigenes Anzeigegerät im Kraftfahrzeug eingebaut werden muss. Damit sind zusätzliche Kosten und Flächenverbrauch im Armaturenbrett verbunden.The disadvantage of this solution is that for this own display device must be installed in the motor vehicle. That means additional Costs and land use connected in the dashboard.

Die beiden Anzeigegeräte, deren Skalen in keiner Beziehung zueinander stehen, müssen vom Fahrer in ständigem Wechsel beobachtet werden. Dies ist unübersichtlich und ermüdend.The two display devices, their Scales have no relation to each other, have to be constantly changed by the driver to be watched. This is confusing and tiring.

Ziel dieses Patents ist die Beseitigung der genannten Nachteile durch die integrierte Anzeige der Geschwindigkeit, der Drehzahl und des geschalteten Gangs in einem gemeinsamen Gerät.The purpose of this patent is to eliminate it the disadvantages mentioned by the integrated display of the speed, the speed and the shifted gear in a common device.

Die Grundlage hierzu ist das für jede Gangstufe konstante Übersetrungsverhältnis zwischen Kurbelwelle und Antriebsrädern, aus dem sich eine direkte Proportionalität zwischen Motordrehzahl und Geschwindigkeit ergibt.The basis for this is for each gear level constant transmission ratio between crankshaft and drive wheels, which gives a direct proportionality between engine speed and speed results.

Erfindungsgemäß wird vorgeschlagen, unter der üblicherweise analog dargestellten Geschwindigkeitsanzeige in einem Fenster die Motordrehzahl in Abhängigkeit von dem jeweils geschalteten Gang so darzustellen, dass die in direkter Proportionalität zueinander stehenden Skalenwerte so unter einander stehen, dass die Messwerte mit einer gemeinsamen Markierung z.B. in Form eines Zeigers, eines Leuchtbandes oder eines Stegs angezeigt werden.According to the invention, it is usually proposed analog speed display shown in a window Motor speed depending of the gear selected in each case so that the direct proportionality the scale values that are in relation to each other are such that the measured values with a common marking e.g. in form of Pointer, a light strip or a web are displayed.

Diese Darstellungsform hat den Vorteil, dass sie raumsparend gebaut werden kann und die angezeigten Messwerte vom Kraftfahrzeugfahrer wesentlich schneller und weniger ermüdend erfasst werden.This form of presentation has the advantage that it can be built to save space and the displayed measured values recorded by the motor vehicle driver much faster and less tiring become.

Erstmals wird dem Fahrer mit dieser Darstellung in übersichtlicher, schnell erfassbarer Form die Zuordnung der optimalen Drehzahl, sowie der Grenzbereiche des Motors zur entsprechenden Geschwindigkeit möglich.For the first time, the driver is using this Presentation in a clear, quickly ascertainable form the assignment of the optimal speed, as well the limit ranges of the motor at the corresponding speed possible.

Der Patentschrift sind drei Zeichnungen beigefügt, auf denen mit 1 und 2 der Anzeigeverlauf der Geschwindigkeit, der Drehzahl und Gangstufe über den Bereich von vier Gängen dargestellt ist. 3 zeigt die genannten Größen mit fünf Gangstufen.Three drawings are attached to the patent, on which with 1 and 2 the display course of the speed, the speed and gear stage is shown over the range of four gears. 3 shows the sizes mentioned with five gears.

1 zeigt die Geschwindigkeitsskala 1 mit feststehender Beschriftung, wie in herkömmlichen Tachometern. 1 shows the speed scale 1 with fixed labeling, as in conventional tachometers.

Die Drehzahlskala 2 kann hier aus vier halbrunden Streifen bestehen, welche mit dem entsprechenden Gang in das Fenster eingeschoben werden oder sie können als LCD-Anzeige in das Fenster eingeblendet werden.The speed scale 2 can consist of four semicircular strips, which are inserted into the window with the corresponding aisle, or they can be displayed in the window as an LCD display.

Die Einteilung der Drehzahlskala 2 in dem darunter liegenden Fenster ändert sich dabei dem jeweiligen Übersetzungsverhältnis der Gangstufe entsprechend und verhält sich so immer proportional zur Geschwindigkeitsskala.The division of the speed scale 2 in the window below, the gear ratio changes accordingly and always behaves proportionally to the speed scale.

Sie wird dabei so justiert, dass unter jedem Geschwindigkeitswert der entsprechende Drehzahlwert steht.It is adjusted so that the corresponding speed value under each speed value stands.

So zeigt die Tachometernadel 3 neben der gefahrenen Geschwindigkeit gleichzeitig die entsprechende Drehzahl des Motors an.So shows the speedometer needle 3 in addition to the speed traveled, the corresponding engine speed.

2 zeigt die Doppelarmatur komplett in LCD-Ausführung. Hier ist die Tachometernadel durch ein wanderndes Leuchtband 4 ersetzt bei sonst gleicher Anzeigeform wie bei 1. 2 shows the double fitting completely in LCD version. Here is the speedometer needle through a wandering light band 4 replaced with otherwise the same display form as with 1 ,

3 zeigt die Doppelarmatur ebenfalls in LCD-Ausführung mit einem in der Mitte feststehenden senkrechten Markierungssteg 5, der zwei übereinander stehende Fenster überdeckt. In das obere Fenster wird die mit der Geschwindigkeit wandernde Geschwindigkeitsskala 1 eingeblendet und in das untere Fenster die Drehzahlskala 2, wobei die Skalenteilung wieder so gewählt ist, dass sie sich dem jeweiligen Übersetzungsverhältnis der Gangstufe entsprechend proportional zur Geschwindigkeitsskala 1 verhält. Die Drehzahlskala wird dabei ebenfalls so justiert, dass unter jedem Geschwindigkeitswert der entsprechende Drehzahlwert steht. 3 shows the double armature also in LCD version with a vertical marker bar fixed in the middle 5 , which covers two windows one above the other. In the upper window the speed scale moving with the speed is shown 1 appears and the speed scale in the lower window 2 , where the scale division is again chosen so that it is proportional to the speed ratio in accordance with the respective gear ratio of the gear stage 1 behaves. The speed scale is also adjusted so that the corresponding speed value is below each speed value.

So wird auch hier mit einem Markierungssteg gleichzeitig die Geschwindigkeit und die Drehzahl angezeigt.This is also the case with a marking bridge at the same time the speed and speed are displayed.

Die Darstellungsformen in LCD-Ausführung haben den Vorteil der voll elektronischen Anzeige ohne Mechanik, verbunden mit der übersichtlichen und gut erfassbaren analogen Darstellungsform der permanent mit unterschiedlicher Geschwindigkeit wechselnden Messwerte wie der Fahrgeschwindigkeit und der Motordrehzahl.The display forms in LCD version have the advantage of fully electronic display without mechanics with the clear and easy-to-grasp analog form of representation of the permanent with different Speed changing measured values such as driving speed and the engine speed.

Die Skalen innerhalb der Fenster werden zweckmäßigerweise in Leuchtschrift dargestellt. Die Drehzahlskala 2 kann farbig unterlegt werden. So sind die einzelnen Bereiche besonders leicht zu erfassen.The scales within the windows are expediently shown in neon letters. The speed scale 2 can be highlighted in color. This makes the individual areas particularly easy to grasp.

Der optimale Drehzahlbereich kann grün, der untere und obere Randbereich gelb und der kritische obere Drehzahlbereich kann orange abgesetzt werden.The optimal speed range can green, the lower one and upper edge area yellow and the critical upper speed range can be highlighted in orange.

Zur besseren Übersicht kann zusätzlich der jeweils geschaltete Gang angezeigt werden.For a better overview, the each gear selected is displayed.

Die Drehzahl- und Ganganzeigen können einzeln zuschaltbar ausgeführt werden.The speed and gear displays can be individually can be switched on become.
