Abstract

L’invention concerne un procédé de détection de plausibilité d’une mesure de température de fluide (Tf) de refroidissement dans un circuit caloporteur d’un moteur thermique de véhicule automobile. Pour une durée prise à partir du démarrage (D) du moteur thermique supérieure à un seuil de durée supérieur (t2) prédéterminé, quand une température du fluide (Tf) en vigueur est inférieure ou supérieure à la consigne de température d’un seuil de consigne calibrable et qu’un gradient (ΔTf) de deux températures de fluide prises entre un intervalle de temps (i) prédéterminé est, en valeur absolue, supérieur à un seuil de gradient calibrable, le thermostat est ouvert au-dessus d’un rapport cyclique maximal prédéterminé et ledit au moins un moyen de ventilation accéléré est activé, avec, après attente d’un délai prédéterminé, si le gradient (ΔTf) de température de fluide (Tf) n’est pas inférieur à zéro, il est effectué un diagnostic d’une mesure de température non plausible.
