Abstract

L'invention porte sur un procédé de gestion d'un couple de moteur thermique dans une phase de reprise d'injection (4a) de carburant après une coupure d'injection (5b) dans le moteur thermique. Il est prédéterminé un couple minimal statique (1) pour servir de couple minimal (2) pour le moteur thermique et assurer une stabilité d'une combustion dans le moteur. Lors d'une phase de reprise d'injection (4a) suivant la coupure d'injection (5b), il est procédé au remplacement, comme couple minimal (2), du couple minimal statique (1) par un couple minimal dynamique (3) inférieur au couple minimal statique (1) pendant une durée de maintien (6) correspondant à un nombre prédéterminé de passages effectifs de Points Morts Hauts dans un ou des cylindres du moteur thermique et à une remontée du couple minimal (2) vers le couple minimal statique (1) quand ledit nombre prédéterminé est dépassé.
