Title
(EN) IMPLEMENT HITCH CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE D'ATTELAGE D'INSTRUMENT
Abstract
(EN)
A control system (42) for an implement hitch of an agricultural vehicle, wherein the hitch is mounted to the vehicle and includes one or more hydraulic cylinders (54) or other actuators operable to raise and lower the hitch between minimum and maximum heights relative to the vehicle and hold the hitch static at one or more heights between the minimum and maximum heights. The control system (42) includes a rocker control device (40) having a first operating position (C) and being movable in a first direction to a first limit position (A) and in a second direction to a second limit position (E). An electronic control unit (ECU 26) connected to the rocker control device (40) is configured to control operation of the or each of the hydraulic cylinders (54) or actuators and thereby control raising and lowering of the hitch in response to user operation of the rocker control device (40). The ECU (26) is operable to control raising and lowering of the hitch according to one of two or more control modes, and to switch between said control modes in response to a predetermined first actuation operation of the same rocker control device (40).
(FR)
L'invention concerne un système de commande (42) pour un attelage d'instrument d'un véhicule agricole, l'attelage étant monté sur le véhicule et comprenant un ou plusieurs vérins hydrauliques (54) ou d'autres actionneurs utilisables pour lever et abaisser l'attelage entre des hauteurs minimale et maximale par rapport au véhicule et maintenir l'attelage statique à une ou plusieurs hauteurs entre les hauteurs minimale et maximale. Le système de commande (42) comprend un dispositif de commande à bascule (40) ayant une première position de fonctionnement (C) et étant mobile dans une première direction vers une première position limite (A) et dans une seconde direction vers une seconde position limite (E). Une unité de commande électronique (ECU 26) reliée au dispositif de commande à bascule (40) est conçue pour commander le fonctionnement du ou des vérins hydrauliques (54) ou actionneurs et ainsi commander l'élévation et l'abaissement de l'attelage en réponse à l'actionnement par l'utilisateur du dispositif de commande à bascule (40). L'ECU (26) permet de commander l'élévation et l'abaissement de l'attelage selon un mode de commande parmi deux modes de commande ou plus, et la commutation entre lesdits modes de commande en réponse à une première opération d'actionnement prédéterminée dudit dispositif de commande à bascule (40).
