Abstract

L’invention concerne un procédé de limitation d’une température de fluide de refroidissement d’un moteur thermique en fonction d’une puissance (P) délivrée par le moteur, la température du fluide (T°C) étant régulée par ouverture de régulation d’un circuit d’échange thermique pour le fluide au-dessus d’une première température (T1°C) prédéterminée de consigne. Au moins comme conditions minimales, quand la puissance (P) du moteur dépasse un seuil (SP) de puissance prédéterminé et que la température du fluide (T°C) est supérieure à une deuxième température (T2°C) prédéterminée inférieure à la première température (T1°C) de consigne, le circuit d’échange thermique est ouvert par anticipation à partir de la deuxième température (T2°C).
