Title (EN) MACHINE EMPLOYING CAB MOUNTS AND METHOD FOR CONTROLLING CAB MOUNTS BASED ON OPERATOR INPUT
(FR) ENGIN EMPLOYANT DES SUPPORTS DE CABINE ET PROCÉDÉ DE COMMANDE DES SUPPORTS DE CABINE EN FONCTION DE SAISIES DE L'OPÉRATEUR
Abstract:
(EN) A machine (100) employing controllable mounts (106) and a method for controlling such mounts (106) based on operator input are disclosed. The controllable mount (106) may include a housing (108), a pin (120), rheological fluid (116) within the housing (108) and coils (131) provided proximate to the rheological fluid (116). As current is applied to the coils (131), the apparent viscosity of the rheological fluid (116) is increased, and in so doing so is the stiffness and damping of the controllable mount (106). Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts (106) should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback. This can be done through an operator interface (188) that enables an operator to specifically set the current to each mount (106), or enter other information whereupon a processor (168) of the control system (182) executes the necessary algorithm (262) to provide the operator with the optimum level of feedback.
(FR) On décrit un engin (100) employant des supports pilotables (106) et un procédé de commande desdits supports (106) en fonction de saisies de l'opérateur. Le support pilotable (106) peut comprendre une enveloppe (108), un axe (120), un fluide rhéologique (116) à l'intérieur de l'enveloppe (108) et des bobines (131) installées à proximité du fluide rhéologique (116). Lorsqu'un courant est appliqué aux bobines (131), la viscosité apparente du fluide rhéologique (116) est augmentée et, ce faisant, il en est de même pour la rigidité et l'amortissement du support pilotable (106). En fonction de divers facteurs, l'opérateur peut souhaiter un niveau particulier de renvoi de sensations. Par exemple, lors de travaux d'aplanissement, l'opérateur peut souhaiter ressentir chaque vibration et les supports pilotables (106) doivent donc être aussi rigides que possible. La présente invention confère donc à l'opérateur la capacité de sélectionner le niveau souhaité de renvoi de sensations. Cela peut être réalisé par l'intermédiaire d'une interface (188) d'opérateur qui permet à un opérateur de régler spécifiquement le courant envoyé à chaque support (106) ou de saisir d'autres informations, un processeur (192) du système (182) de commande exécutant alors l'algorithme (262) nécessaire pour assurer à l'opérateur le niveau optimal de renvoi de sensations.
