Abstract

L’invention concerne une méthode d’échantillonnage (1) permettant de définir un nombre de points de mesure nécessaire et suffisant pour l’étalonnage de lois de commande d’un moteur à essence. La méthode d’échantillonnage (1) comporte une étape d’établissement (13) de configurations de déphasage issues de plusieurs configurations angulaires des arbres à cames d’admission et d’échappement du moteur à essence. Consécutivement, la méthode d’échantillonnage comporte une étape de sélection (15) de plusieurs points de mesure de pression d’air injecté dans le moteur à essence par le répartiteur. Bien évidemment, la sélection des configurations angulaires et des points de mesure de pression sont réalisées de manière à modéliser avec suffisamment de précision le comportement du moteur et les phénomènes physiques opérants dans ledit moteur, sans pour autant les suréchantillonner. Fig. 1The invention relates to a sampling method (1) making it possible to define a number of measurement points necessary and sufficient for the calibration of the control laws of a gasoline engine. The sampling method (1) comprises a step of establishing (13) phase shift configurations resulting from several angular configurations of the intake and exhaust camshafts of the gasoline engine. Consecutively, the sampling method comprises a step of selecting (15) several points for measuring the air pressure injected into the gasoline engine by the dispatcher. Obviously, the selection of the angular configurations and the pressure measurement points are carried out in such a way as to model with sufficient precision the behavior of the engine and the physical phenomena operating in said engine, without oversampling them.
