Abstract

L'invention concerne un procédé, et son dispositif correspondant, de traitement d'un signal de pression (p) issu d'un capteur de pression monté dans une chambre de combustion, en vue de détecter une combustion dans un moteur à combustion interne, comprenant les étapes consistant à :- fournir le signal de pression (p),- filtrer le signal de pression (p) par des moyens de filtrage ayant un gain variable (7),- établir un signal de sortie (out) représentatif du signal de pression (p) filtré, et- établir un signal (e) représentatif de l'erreur entre le signal de pression (p) et le signal de sortie (out).L'invention est essentiellement caractérisée en ce qu'elle comprend en outre une étape consistant à :- déterminer si la combustion a eu lieu pendant une phase de détente du cycle thermodynamique.
