Abstract
L'invention concerne un procédé d'estimation du couple moteur d'un moteur à combustion interne en fonctionnement, comprenant une étape de détermination d'une consigne de couple moteur et caractérisé en ce que : -on détermine une richesse de consigne (Φc) à partir de la consigne de couple moteur, -on détermine la richesse réelle (Φfonc) de fonctionnement du moteur, -on applique à la consigne de couple moteur un coefficient (Ccor) de correction obtenu à partir de la richesse de consigne (Φc) et de la richesse réelle (Φfonc) pour obtenir le couple moteur réel du moteur en fonctionnement.
