Abstract

L'invention porte sur un procédé de correction d'une avance à l'allumage curative appliquée à un moteur thermique dès qu'une apparition de cliquetis lors du fonctionnement du moteur est détectée, l'avance à l'allumage étant appliquée et progressivement réduite à une première vitesse de réduction, caractérisé en ce que le procédé comprend une étape de détection d'une phase transitoire du moteur thermique correspondant à un gradient de régime moteur ou de charge du moteur variant de plus de 15% et quand il est détecté une phase transitoire et qu'une avance à l'allumage curative a été antérieurement appliquée, la réduction de l'avance à l'allumage (Deg A) curative s'effectue à une deuxième vitesse de réduction supérieure à la première vitesse de réduction.
