Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Erkennung einer Winkelstellung eines Wählhebels in einem Kraftfahrzeug.The The invention relates to an apparatus and a method for detection an angular position of a selector lever in a motor vehicle.
In modernen Kraftfahrzeugen, insbesondere Lastkraftwagen, werden heutzutage Wählhebel eingesetzt, die unterschiedliche Schaltstellungen unterschiedlichen Programmen der Getriebe zuordnen. Ein Problem, das sich hierbei stellt ist die Notwendigkeit der Justage der Schaltstellungen zu den Schaltelementen, welche das gewünschte Programm auswählen. Als Nachteilig stellt sich hierbei der hohe zeitliche Aufwand und Fehleranfälligkeit dieser Justage bei der Montage der Wählhebeleinheit dar.In modern motor vehicles, especially trucks, are nowadays selector lever used, the different switch positions different Assign programs to the gearboxes. A problem here is the need to adjust the switch positions the switching elements which select the desired program. When The disadvantage here is the high time and error prone this adjustment during assembly of the selector unit.
Die Aufgabe der Erfindung ist es die Nachteile aus dem Stand der Technik zu überwinden und eine Vorrichtung und ein Verfahren bereit zu stellen, so daß auf eine Justage der Schaltstellungen verzichtet werden kann. Darüber hinaus stellt sich die Aufgabe eine konstruktiv einfache und wirtschaftlich günstige Lösung zu entwickeln.The The object of the invention is the disadvantages of the prior art to overcome and to provide an apparatus and a method so that a Adjustment of the switch positions can be dispensed with. Furthermore the task is a structurally simple and economically viable solution develop.
Die Aufgabe der Erfindung wird in Bezug auf die Vorrichtung dadurch gelöst, dass die Vorrichtung zur Erkennung einer Winkelstellung eines Wählhebels aus
- – einem in mindestens eine Richtung schwenkbar in einem Gehäuse befestigtem Wählhebel,
- – mindestens einem ortsfest im Gehäuse befestigtem Sensor, wobei der Sensor ein die magnetische Feldstärke und/oder die magnetische Feldrichtung erfassender Sensor ist und
- – einer mit dem Sensor verbundenen Auswerteelektronik
- A selector lever pivotally mounted in a housing in at least one direction,
- - At least one fixedly mounted in the housing sensor, wherein the sensor is a magnetic field strength and / or the magnetic field direction detecting sensor and
- - A transmitter connected to the sensor
Durch die erfindungsgemäße Lösung, ist nun die Möglichkeit geschaffen auf die Justage der mechanischen und elektronischen Komponenten zu verzichten. Die Erfindung ist gekennzeichnet durch den Einsatz einer analogen Positions- oder Wegmessung. Die Schaltstellungen werden von der erfindungsgemäßen Vorrichtung mittels eines Einlernvorgang der Schaltpunkte an einem Endprüfplatz oder durch einen Einlernschritt an einem Platz innerhalb der Fertigungs-, Prüf- und/oder Abnahmekette erlernt, bei dem zumindest die folgenden Verfahrensschritte eingehalten sind:
- – Betätigung des Wählhebel in eine mechanisch fixierte Anschlagstellung oder eine Endstellung,
- – Einlesen und Abspeichern der Position,
- – Betätigung des Wählhebel in eine zweite oder weitere mechanisch fixierte Anschlagstellungen oder entgegengesetzte Endstellung,
- – Einlesen der zweiten oder weiterer Positionen und/oder Endstellung bzw. Endstellungen,
- – Errechnen aller weiter vorhandenen Zwischenstellungen,
- – Permanente Abspeicherung der Positionsstellungen und zugehörigen Daten des Wählhebels unter anderem zur Positionsauswertung in einem EEProm oder einer anderer permanenten Speichertechnologie.
- Actuation of the selector lever in a mechanically fixed stop position or an end position,
- - reading and saving the position,
- Actuation of the selector lever in a second or further mechanically fixed stop positions or opposite end position,
- Reading the second or further positions and / or end positions or end positions,
- - calculating all existing intermediate positions,
- - Permanent storage of the position and associated data of the selector lever, among other things, for position evaluation in an EEPROM or other permanent storage technology.
Durch das beschriebene Verfahren eines Einlernvorganges wird der Vorteil erreicht, dass eine mechanische Justage zwischen den Sensor-/Erkennungselementen und der Mechanik des Wählhebels entfällt.By The method described a teach-in process is the advantage achieved that a mechanical adjustment between the sensor / detection elements and the mechanics of the selector lever is eliminated.

Wie
oben beschrieben werden in der Konstruktion zwei Zahnräder
- – Zeitgleich und in gleicher Stärke auftretende Änderungen/Störungen der Feldstärke in den Sensoren werden aus dem Messwert elimiert,
- – es werden keine Absolutwerte gemessen sondern Widerstands- bzw. Spannungsverhältnisse an den Sensoren, hierdurch wird unter anderem eine Unempfindlichkeit gegen Drift, wie zum Beispiel ein Alters- oder Temperaturdrift, erreicht,
- – Erkennung von Fehlern in einem der Sensoren,
- – Erkennung von Defekten in der Messbrücke und
- – Erkennung von Kurzschlüssen und Unterbrechungen.
- - At the same time and in the same strength occurring changes / disturbances of the field strength in the sensors are eliminated from the measured value,
- - Absolute values are not measured, but rather resistance or voltage conditions at the sensors, which, among other things, results in insensitivity to drift, such as age or temperature drift.
- - detection of errors in one of the sensors,
- - Detection of defects in the measuring bridge and
- - Detection of short circuits and interruptions.
