Abstract

L'invention concerne un organe de commande d'un engin de construction, telle une pelle hydraulique, permettant de creuser le sol, doté d'un moyen de détection d'angle (20-22) destiné à détecter la position d'un mécanisme de bras articulé en termes de données d'angle, d'un moyen de conversion (26) permettant de convertir les données d'angle détectées en données de déplacement en extension/contraction d'un vérin (120-122) correspondant, et d'un moyen de commande (1) permettant de commander le vérin (120-122), en vue d'un déplacement en extension/contraction requis, selon des données obtenues de déplacement en extension/contraction. Ainsi, il est possible de commander l'état et la position d'un élément de travail (400) de façon précise et stable, tout en maintenant des coûts faibles.
