Abstract

L’invention concerne un véhicule de travail roulant comportant un bras de levage et un système de commande de direction. Le système de commande de direction est configuré pour recevoir un signal de demande de braquage et un paramètre d’orientation du bras de levage et pour générer un signal de consigne de braquage (D, E) représentatif d’un angle de braquage des roues directrices et destiné à piloter un actionneur de braquage. Le système de commande de direction comporte un module de filtrage (103) configuré pour déterminer un premier plafond de vitesse de variation en fonction du paramètre d’orientation du bras de levage et pour générer le signal de consigne de braquage (D, E) en fonction du signal de demande de braquage de manière qu’une vitesse de variation du signal de consigne de braquage ne dépasse pas le premier plafond de vitesse de variation. Figure pour l’abrégé : Fig. 9
