Description

20 25 30 534 890 Sammanfattning av uppfinningen Ett syfte med den föreliggande uppfinningen är att tillhandahålla en lösning på problemet med manövrering av ett upphängningsnivåsystem i ett motorfordon. Ett annat syfte med uppfinningen är att tillhandahålla en anordning för manövrering av ett upphängningsnivåsystem som är kompakt och lätthanterligt vid manövrerandet av upphängningsnivàsystemet. l enlighet med en aspekt av den föreliggande uppfinningen uppnås ovanstående syften med en anordning för manövrering av ett upphängningsnivåsystem i ett motorfordon. Anordningen innefattar ett första manuellt manövrerat reglage anordnat för att kommunicera med nämnda upphängningsnivåsystem för manövrering av detsamma. Det första manuellt manövrerade reglaget är vidare anordnat för att vara mekaniskt manövrerbart i ett flertal positioner, där varje position selekterar en funktion från ett urval av flera funktioner vilka upphängningsnivåsystemet tillhandahåller. Summary of the Invention An object of the present invention is to provide a solution to the problem of operating a suspension level system in a motor vehicle. Another object of the invention is to provide a device for operating a suspension level system which is compact and easy to handle when operating the suspension level system. In accordance with one aspect of the present invention, the above objects are achieved with an apparatus for operating a suspension level system in a motor vehicle. The device comprises a first manually operated control arranged to communicate with said suspension level system for operating the same. The first manually operated control is further arranged to be mechanically operable in a number of positions, where each position selects a function from a selection of your functions which the suspension level system provides.

Med en anordning för manövrering av ett upphängningsnivåsystem i enlighet med uppfinningen, kan alla funktioner som upphängningsnivåsystemet tillhandahåller manövreras från en enda anordning, vilket förenklar manövreringen av upphängningsnivàsystemet. Panelutrymme kan sparas som ett resultat av att alla funktioner manövreras från en anordning, jämfört med lösningar som innefattar ett flertal spridda separata tryckknappar eller lösningar innefattande minst en manöverenhet och minst en optisk bildskärmsenhet. l enlighet med den föreliggande uppfinningen behöver följaktligen endast en anordning monteras på panelen, vilket också medför kortare monteringstid vid montering av paneler som innefattar en anordning i enlighet med uppfinningen.With a device for operating a suspension level system in accordance with the invention, all functions provided by the suspension level system can be operated from a single device, which simplifies the operation of the suspension level system. Panel space can be saved as a result of all functions being operated from one device, compared to solutions that include a number of scattered separate pushbuttons or solutions comprising at least one control unit and at least one optical display unit. Accordingly, in accordance with the present invention, only one device needs to be mounted on the panel, which also results in a shorter mounting time when mounting panels that include a device in accordance with the invention.

Vidare reduceras antalet kommunikationsstift som krävs för att ansluta manöveranordningen till upphängningsnivåsystemet som ett resultat av att endast en uppsättning kommunikationsstift krävs i enlighet med den föreliggande uppfinningen, att jämföras med en uppsättning kommunikationsstift per tryckknapp i enlighet med 10 15 20 25 30 534 890 teknikens ståndpunkt som i den ovan beskrivna lösningen. Om exempelvis en uppsättning kommunikationsstift motsvarar tre stift och vi antar att åtta tryckknappar används för manövreringen av upphängningsnivåsystemet samt att en uppsättning stift per tryckknapp/manöveranordning krävs för att kommunicera med upphängningsnivåsystemet, så reduceras antalet kommunikationsstift från 24 (3x8) till 3 (3x1). Följaktligen kommer även kostnaden för tillverkning och underhålla av anordningen för reglering av upphängningsnivåsystemet att reduceras.Furthermore, the number of communication pins required to connect the control device to the suspension level system is reduced as a result of only one set of communication pins being required in accordance with the present invention, compared to one set of communication pins per pushbutton in accordance with the prior art. in the solution described above. For example, if a set of communication pins corresponds to three pins and we assume that eight pushbuttons are used to operate the suspension level system and that one set of pins per pushbutton / control device is required to communicate with the suspension level system, the number of communication pins is reduced from 24 (3x8) to 3 (3x1). Consequently, the cost of manufacturing and maintaining the suspension level control device will also be reduced.
