Abstract

L'invention porte principalement sur un procédé de diagnostic de fonctionnement d'un turbocompresseur de moteur thermique, caractérisé en ce que ledit procédé comporte: - une étape de réalisation d'une première comparaison entre une position mesurée (Pos_mes) du système de décharge et un seuil d'activation (S_act_min, S_act_max) défini en fonction de paramètres liés au fonctionnement du moteur thermique, - une étape de détermination d'un écart de boucle (Eb) égal à la différence entre une consigne de position du système de décharge et la position mesurée (Pos_mes) du système de décharge, - une étape de réalisation d'une deuxième comparaison entre l'écart de boucle (Eb) précédemment déterminé et un seuil de détection (S_det_pos, S_det_neg), et - une étape de remontée de défauts et/ou de reconfiguration du moteur thermique en fonction de la première comparaison et de la deuxième comparaison précédemment effectuées.The invention relates mainly to a method for diagnosing the operation of a turbocharger of a heat engine, characterized in that said method comprises: - a step of carrying out a first comparison between a measured position (Pos_mes) of the discharge system and an activation threshold (S_act_min, S_act_max) defined as a function of parameters linked to the operation of the heat engine, - a step of determining a loop deviation (Eb) equal to the difference between a position reference of the discharge system and the measured position (Pos_mes) of the discharge system, - a step of carrying out a second comparison between the loop deviation (Eb) previously determined and a detection threshold (S_det_pos, S_det_neg), and - a step of raising faults and / or reconfiguration of the heat engine as a function of the first comparison and the second comparison previously carried out.
