Abstract

L'invention concerne un procédé d'apprentissage d'une correction de richesse de carburant d'un moteur thermique froid à une température inférieure à une température minimale prédéterminée de fonctionnement d'une sonde de richesse positionnée dans une ligne d'échappement du moteur. Une correction à froid apprise (Cor f ap) est calculée selon un apprentissage opérant lors d'un démarrage du moteur après qu'un élément de pilotage (UD) d'apprentissage ait délivré une autorisation d'apprentissage (Aut App) selon une condition d'activation (Cond Act) représentative d'un moteur froid. L'autorisation d'apprentissage (Aut App) n'est pas délivrée quand au moins une condition d'inhibition (Cond Inh) représentative d'une atteinte d'une macération dans le moteur pour laquelle au moins un fluide de refroidissement, un fluide de lubrification du moteur et une température d'air admis dans le moteur présentent des températures stables en correspondance avec une température extérieure en vigueur dans une marge de moins de 20%.
