Description

Die Erfindung betrifft eine Anordnung zur Erzeugung eines Positionssignals nach dem Oberbegriff des Hauptanspruchs.The invention relates to an arrangement for generating a Position signal according to the preamble of the main claim.

Die Erfassung der Betriebsstellung einer automatischen Getriebeschaltung mittels Potentiometern ist aus der DE- OS 32 43 461 bekannt. Nach dieser Druckschrift werden an den Stellgliedern, die das Schalten des Getriebes aus­ führen, Potentiometer als Verschiebefühler verwendet. Diese Verschiebefühler sind notwendig, um die Stellung der Stellglieder beim Schaltvorgang rückzumelden und die Funktionsfolge sicherzustellen. Die Stellung des Wähl­ hebels wird, über in der Schrift nicht erwähnte Mittel, direkt an die elektronische Steuereinrichtung des Ge­ triebes übertragen.The detection of the operating position of an automatic Gear shifting using potentiometers is from DE- OS 32 43 461 known. According to this publication, the actuators that switch the transmission off lead, potentiometer used as displacement sensor. These displacement sensors are necessary for the position to report the actuators during the switching process and the Ensure sequence of functions. The position of the dialer lever, by means not mentioned in the Scriptures, directly to the electronic control device of the Ge drive transmitted.

Die Verwendung eines Potentiometers zum Abgriff einzelner genau definierter Positionspunkte kann den Nachteil haben, daß es im Übergangsbereich von einer Position in die andere undefinierte Zwischenpositionen anzeigt. Das Potentiometer meldet in diesem Fall zu spät oder zu früh die Positionsänderung. Ist das Potentiometer einem Wähl­ hebel zugeordnet, muß es sehr genau justiert werden. The use of a potentiometer to tap individual Well-defined position points can have the disadvantage have it in the transition area from a position in which shows other undefined intermediate positions. The In this case, the potentiometer reports too late or too early the change of position. Is the potentiometer one dial assigned to the lever, it must be adjusted very precisely.  

Ferner muß auch die Steuereinheit aufwendig programmiert werden, will man erreichen, daß sowohl die Anzeige- als auch die Getriebesteuerung während solcher Zwischen­ positionen noch eine definierte Position des Wählhebels erkennen soll.Furthermore, the control unit must also be programmed in a complex manner , you want to achieve that both the display and also the transmission control during such intermediate positions a defined position of the selector lever should recognize.

Aufgabe der Erfindung ist es, eine gattungsgemäße An­ ordnung so auszuführen, daß der Meßwert eines Potentio­ meters genau dann von einer elektronischen Steuereinheit ausgewertet wird, wenn sich der Positionswählhebel definiert in der neuen Position befindet.The object of the invention is to provide a generic order so that the measured value of a potentio then exactly from an electronic control unit is evaluated when the position selector lever defined in the new position.

Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The object is achieved with the characteristic Features of claim 1 solved. Other configurations the invention emerge from the subclaims.

Nach der Erfindung wird das Potentiometer mit einem Tast­ schalter kombiniert, der durch eine mit dem Wählhebel verbundene Rastenscheibe betätigt wird. Die Rastenscheibe weist Rastsenken auf, die den einzelnen Wählhebel­ positionen entsprechen. Beim Erreichen einer Rastsenke wird der Tastschalter betätigt. Durch sein Schaltsignal veranlaßt er die elektronische Steuereinheit des Ge­ triebes aus dem vorliegenden Potentiometermeßwert die Wählhebelposition zu ermitteln. Dazu wird in der Steuereinheit der Potentiometermeßwert verglichen mit den für die Rastpositionen gespeicherten Wertebereichen. Der Wertebereich, in dem der Potentiometermeßwert enthalten ist, kennzeichnet die Position des Wählhebels.According to the invention, the potentiometer with a push button switch combined by one with the selector lever connected locking disc is actuated. The locking disk has notches on the individual selector lever correspond to positions. When you reach a notch the button switch is operated. Through its switching signal he causes the electronic control unit of the Ge driven from the present potentiometer measured value Determine selector lever position. This is done in the Control unit the potentiometer measured value compared to the value ranges saved for the locking positions. The Range of values in which the potentiometer measured value is contained indicates the position of the selector lever.

Auf diese Weise erfolgt die Auswertung eines analogen Positionsmeßwertes sozusagen digital nur bei bestimmten Positionen. Das hat den Vorteil, daß die Meßwerte der einzelnen definierten Positionen genügend weit aus­ einanderliegen, um in der Steuerschaltung eine eindeutige Auswertung anhand von Wertebereichen zu gewährleisten. In this way, an analogue is evaluated Position measurement values, so to speak, digitally only for certain Positions. This has the advantage that the measured values of the individual defined positions sufficiently far lie one to the other in the control circuit a unique Ensure evaluation based on value ranges.  

Der Toleranzbereich beim Einbau des Potentiometers wird vergrößert. Bei einem Positionswechsel wird im Steuer­ gerät die alte Position so lange gehalten, bis die neue Position, definiert durch das Schaltsignal, erreicht ist. Ein Wechsel der Positionsanzeige bei Zwischenpositionen wird vermieden. Undefinierte Zwischenwerte müssen nicht durch die Programmierung des Steuergeräts unterdrückt werden.The tolerance range when installing the potentiometer is enlarged. With a change of position is in control the old position is held until the new one Position, defined by the switching signal, is reached. A change in the position display for intermediate positions is avoided. Undefined intermediate values do not have to suppressed by programming the control unit will.

Bei einer bevorzugten Ausführung der Erfindung werden Rastenscheibe und Potentiometer direkt auf der Wählwelle des Fahrzeuggetriebes angebracht. Das hat den Vorteil, daß die Position der Rastenscheibe und des Potentiometers bezüglich der Wählwelle eindeutig festgelegt ist.In a preferred embodiment of the invention Locking disk and potentiometer directly on the selector shaft attached to the vehicle transmission. That has the advantage, that the position of the locking disk and the potentiometer is clearly defined with regard to the selector shaft.

Die Drehbewegung der Wählwelle begünstigt in einer ein­ fachen Ausführungsform die Ausbildung des Potentiometers als Drehpotentiometer.The rotary movement of the selector shaft favors one fold embodiment of the training of the potentiometer as a rotary potentiometer.

Eine besonders kompakte Ausführung ergibt sich, wenn das Potentiometer direkt an der Rastenscheibe angeordnet wird.A particularly compact design results if that Potentiometer arranged directly on the locking disk becomes.

In einer weiteren vorteilhaften Ausführung der Erfindung wird das Potentiometer durch Kontaktpaare ergänzt, die bei bestimmten Stellungen des Wählhebels Signale für weitere Funktionen liefern, zum Beispiel Signale an das Rückfahrlicht- oder das Anlaßsperrelais. So können be­ stimmte Funktionen unabhängig von der elektronischen Steuerschaltung ausgelöst werden.In a further advantageous embodiment of the invention the potentiometer is supplemented by contact pairs that signals for at certain positions of the selector lever provide additional functions, for example signals to the Reversing light or the starter lock relay. So be agreed functions regardless of the electronic Control circuit are triggered.

In einer bevorzugten Ausführung der Erfindung fixiert die Rastenscheibe gleichzeitig den Wählhebel. Hierzu rasten federbelastete Fixierungsmittel in die Rastsenken der Rastenscheibe ein und die Rastenscheibe ist fest mit dem Wählhebel verbunden.In a preferred embodiment of the invention, the Locking disc at the same time the selector lever. To do this, rest spring-loaded fixation in the notches of the Locking washer and the locking washer is fixed to the Selector lever connected.

Fig. 2 bruchstückhaft ein Getriebegehäuse mit einer Rastenscheibe auf einer Wählwelle mit Dreh­ potentiometer. Fig. 2 fragmentary a gear housing with a locking disk on a selector shaft with rotary potentiometer.

Nach Fig. 1 sitzt in einem Getriebegehäuse 1 auf einer Wählwelle 2 eine Rastenscheibe 3 mit einem auf ihr ange­ ordneten Potentiometer 4. Die Wählwelle 2 wird durch den Wählhebel 5 über die Wählstange 6 und die drehfest auf ihr befestigte Rastenscheibe 3 in die Getriebevorwähl­ stellung P, R, N usw. bewegt. Die Fixierung der vorge­ sehenen Vorwählstellungen übernimmt dabei eine Rasten­ feder 7. Die Rastenfeder 7 ist mit einem Ende am Ge­ triebegehäuse 1 befestigt, das andere, freie Ende trägt einen Rollkörper 8, der in Rastsenken 9 der Rastenscheibe 3 eingreift. Der Rollkörper 8 fixiert die Rastenscheibe 3 und den mit ihr verbundenen Wählhebel 5.According to Fig. 1, a notched disk 3 is seated in a transmission housing 1 on a selector shaft 2 with a arranged on it is Potentiometer 4. The selector shaft 2 is moved by the selector lever 5 via the selector rod 6 and the non-rotatably fastened locking disk 3 in the gear pre-selection position P, R, N, etc. The fixation of the pre-selected positions takes over a detent spring 7 . The detent spring 7 is connected to one end on the Ge gear housing 1 is fixed, the other, free end carries a rolling body 8, which engages the notched disk 3 in latch recesses. 9 The rolling element 8 fixes the locking disk 3 and the selector lever 5 connected to it .

Wird der Wählhebel 5 in eine andere Stellung bewegt, wälzt der Rollkörper 8 auf dem Umfang der Rastenscheibe 3 ab und rastet in die nächste Rastsenke ein. Dadurch wird ein Tastschalter 10 im Getriebegehäuse 1 betätigt. Das Signal des Tastschalters 10 wird einer elektronischen Steuereinheit 11 zugeführt und bewirkt, daß die am Po­ tentiometer 4 anliegende Spannung gemessen wird.If the selector lever 5 is moved to another position, the rolling element 8 rolls on the circumference of the locking disk 3 and engages in the next locking depression. As a result, a pushbutton switch 10 in the transmission housing 1 is actuated. The signal of the key switch 10 is supplied to an electronic control unit 11 and causes the voltage applied to the potentiometer 4 to be measured.

Beim Vergleich des Meßwertes mit den in der Steuereinheit abgespeicherten Wertebereichen für die einzelnen Vorwahl­ stellungen des Getriebes, ergibt sich die tatsächliche Wählhebelstellung in der Steuereinheit. Diese wird zur Anzeige 12 gebracht und beeinflußt nach Programm die symbolisch als Kästchen dargestellten Getriebestell­ glieder 13. Durch weitere Kontaktpaare 14, 15 und 16, 17 werden, unabhängig von der elektronischen Steuereinheit 11, Rückfahrlichtrelais 18 und Anlaßsperrelais 19 direkt gesteuert.When comparing the measured value with the value ranges stored in the control unit for the individual preselection positions of the transmission, the actual selector lever position in the control unit is obtained. This is brought to the display 12 and influences the program symbolically represented as a box gear member 13 according to the program. Additional contact pairs 14 , 15 and 16 , 17 control the reversing light relay 18 and the starter inhibitor 19 directly, independently of the electronic control unit 11 .

Fig. 2 zeigt ein weiteres Ausführungsbeispiel der Er­ findung. Soweit Bauteile in ihrer Funktion vergleichbar sind, tragen sie die gleichen Bezugsziffern wie in Fig. 1. Es ist eine Wählwelle 2 in einem Getriebegehäuse 1 drehbar gelagert. Auf der Wählwelle 2 ist verdrehfest ein Drehpotentiometer 4′ neben der ebenfalls verdrehfest auf der Wählwelle 2 sitzenden Rastenscheibe 3 angebracht. Beim Verdrehen der Wählwelle 2 wälzt ein Rollkörper 8 auf dem Umfang der Rastenscheibe 3 ab und rastet in die nächste Rastsenke ein. Ein dadurch betätigter Tast­ schalter 10 veranlaßt eine hier nicht gezeichnete Steuereinheit 11 die am Drehpotentiometer 4′ anliegende Spannung zu messen. Die Steuereinheit ermittelt dann in der nach Fig. 1 beschriebenen Weise die jeweilige Position des Wählhebels. Fig. 2 shows another embodiment of the invention. Insofar as components are comparable in their function, they have the same reference numbers as in FIG. 1. A selector shaft 2 is rotatably mounted in a gear housing 1 . On the selector shaft 2 , a rotary potentiometer 4 'is attached in a rotationally fixed manner in addition to the detent disk 3, which is also non-rotatably mounted on the selector shaft 2 . When the selector shaft 2 is rotated, a rolling element 8 rolls on the circumference of the detent disk 3 and engages in the next notch. A button 10 actuated thereby causes a control unit 11, not shown here, to measure the voltage applied to the rotary potentiometer 4 '. The control unit then determines the respective position of the selector lever in the manner described in FIG. 1.
