Abstract

L'invention porte principalement sur un procédé de contrôle permettant le calcul d'une sensibilité d'au moins un modèle de comportement (H(x)) d'un actionneur de moteur thermique d'un véhicule automobile comportant: - une étape de calcul de la sortie (Y1) dudit modèle (H(x)) sans biais et de stockage de ladite valeur de sortie (Y1) comme valeur de référence, - une étape de calcul de la sortie (Y1) dudit modèle (H(x)) avec un biais appliqué sur une première entrée (X1) de manière à déterminer la sensibilité de ladite sortie du modèle (Y1) à la variation de ladite première entrée (X1), et - une étape de calcul de la sortie (Y1) dudit modèle (H(x)) avec un biais appliqué sur une deuxième entrée (X2) de manière à déterminer la sensibilité de ladite sortie (Y1) dudit modèle (H(x)) à la variation de ladite deuxième entrée (X2).The invention relates primarily to a control method for calculating a sensitivity of at least one behavior model (H (x)) of a motor vehicle engine actuator comprising: a computation step of the output (Y1) of said model (H (x)) without bias and of storing said output value (Y1) as a reference value, - a step of calculating the output (Y1) of said model (H (x) ) with a bias applied to a first input (X1) so as to determine the sensitivity of said output of the model (Y1) to the variation of said first input (X1), and - a step of calculating the output (Y1) of said model (H (x)) with a bias applied to a second input (X2) so as to determine the sensitivity of said output (Y1) of said model (H (x)) to the variation of said second input (X2).
