Abstract

Dispositif et procédé pour le pilotage en traction d’un circuit d’assistance hydraulique. Procédé de contrôle de traction d’un circuit d’assistance hydraulique de véhicule, dans lequel on applique une pression cible (C), et on détermine une pression de consigne (Pc) et une valeur théorique (Vth) d’un paramètre, on applique une consigne de pression (Pls) à la pompe hydraulique (10) égale à la pression de consigne (Pc), on mesure une valeur effective (Ve) dans ledit circuit d’assistance hydraulique, on compare la valeur effective (Ve) mesurée dans ledit circuit d’assistance hydraulique à la valeur théorique (Vth), et si un écart entre la valeur effective (Ve) et la valeur théorique (Vth) est supérieur à une valeur seuil, on réalise une étape (E5) d’ajustement de la consigne dans laquelle on modifie la consigne de pression (Pls) de la pompe hydraulique (10) de manière à ce qu’elle soit égale à une pression effective (Pe), à un coefficient d’ajustement près. Figure pour l’abrégé : Fig. 2.
