Abstract

La présente invention concerne un procédé de commande d'une vanne de recirculation des gaz à l'échappement d'un moteur thermique. Le procédé comporte l'estimation d'un premier paramètre (302) de débit d'air au collecteur d'admission calculé par un premier modèle de rendement volumétrique (300) recevant en entrée une première consigne de déphasage (301). Afin de réduire le temps de réponse de la vanne, le procédé comporte en outre, lors d'une phase transitoire de déphasage, l'estimation d'un deuxième paramètre (305) du débit d'air au collecteur d'admission par un deuxième modèle de rendement volumétrique (303) recevant en entrée une deuxième consigne de déphasage (304) décalée temporellement par rapport à la première consigne de déphasage (301), et, lors de la phase transitoire de déphasage, le calcul de la consigne (306) de la vanne de recirculation est fonction au moins du deuxième paramètres (305) du débit d'air au collecteur d'admission.The present invention relates to a method for controlling a valve for recirculating gases from the exhaust of a heat engine. The method comprises estimating a first parameter (302) of air flow to the intake manifold calculated by a first volumetric efficiency model (300) receiving as input a first phase shift setpoint (301). In order to reduce the response time of the valve, the method further comprises, during a transient phase shift phase, the estimation of a second parameter (305) of the air flow to the intake manifold by a second volumetric efficiency model (303) receiving as input a second phase shift setpoint (304) offset in time with respect to the first phase shift setpoint (301), and, during the transient phase shift phase, the calculation of the setpoint (306) of the recirculation valve is a function of at least the second parameter (305) of the air flow to the intake manifold.
