Abstract

L’invention concerne un procédé de commande d’un système de motorisation, comprenant une chaudière pour chauffer un circuit de liquide de refroidissement avant le démarrage, un circuit d’huile, ledit procédé comprenant la mesure de la température du liquide (1) et la mesure de la température de l’huile (2) du moteur, la comparaison de l’écart entre ces deux températures d’un seuil de température calibrable en fonction des pertes par frottement du moteur, si, après démarrage, l’écart est supérieur audit seuil de température calibrable, une loi de commande détermine un vecteur de consigne du régime moteur déterminant la sortie de démarrage (10) qui est fonction de la température de l’huile (2), et si, après démarrage, l’écart est inférieur audit seuil de température calibrable, une loi de commande détermine un vecteur de consigne du régime moteur déterminant la sortie de démarrage (10) qui est fonction de la température du liquide (1).
