Abstract

L'invention porte sur un procédé de réglage de la consigne de richesse (Consrich sond) lors d'un balayage d'air d'une sonde dite amont disposée dans une ligne d'échappement en sortie d'un moteur thermique et le balayage d'air s'effectuant dans le moteur sur de l'air frais et laissant passer de l'air non brûlé dans la ligne, une régulation de richesse du mélange air/carburant dans le moteur étant effectuée selon une consigne de richesse estimée (Consrich sond) à la sonde amont. La consigne de richesse (Consrich sond) à la sonde amont estimée est réactualisée par un terme correctif (Term) au moins fonction d'un régime moteur (RM) et d'un taux d'air balayé (Tb) pour donner une consigne de richesse réactualisée (Consrich réac) à la sonde amont.
