Title
(EN) AUTOMATIC ARTICULATION FAILURE MODE PROTECTION
(FR) PROTECTION DE MODE DE DÉFAILLANCE D'ARTICULATION AUTOMATIQUE
Abstract
(EN) Activation of an automatic articulation control function in an articulated machine (10) is delayed until error conditions are cleared or a steering angle to alignment angle mismatch is corrected. A controller (102) monitors a selector (110) setting indicating a desire to activate the automatic articulation control function. The controller (102) also evaluates whether conditions such as low ground speed, loss of signal from needed sensors, or articulation misalignment are present. If so, the conditions are monitored and when corrected, the automatic articulation control function is activated. An indicator (204, 206) may be set to inform an operator that the automatic articulation control function is pending activation.
(FR) L'invention concerne l'activation d'une fonction de commande d'articulation automatique dans une machine articulée (10), qui est retardée jusqu'à ce que des conditions d'erreur soient effacées ou qu'un angle de direction de non-concordance d'angle d'alignement soit corrigé. Un contrôleur (102) surveille un réglage de sélecteur (110) indiquant le souhait d'activer la fonction de commande d'articulation automatique. Le contrôleur (102) évalue également si des conditions, telles que la vitesse au sol réduite, la perte de signal à partir de capteurs nécessaires ou un désalignement d'articulation, sont présentes. Si tel est le cas, les conditions sont surveillées et, lorsqu'elles sont corrigées, la fonction de commande d'articulation automatique est activée. Un indicateur (204, 206) peut être réglé pour informer un opérateur que la fonction de commande d'articulation automatique est en attente d'activation.
