Abstract

L’invention concerne un ensemble de pilotage, et un procédé de mise en œuvre, d’un système de démarrage-arrêt automatique d'un moteur prévu comme source d'entraînement d'un véhicule, l’ensemble comprenant : - un moyen de commande du système de démarrage-arrêt automatique actionné en fonction de conditions de roulage dudit véhicule, - un premier et un deuxième moyens de détermination pour déterminer une température du dispositif de traitement et une température des gaz d’échappement, - un moyen de comparaison pour comparer la température du dispositif de traitement avec une première valeur prédéfinie, - un deuxième moyen de détermination pour déterminer une température des gaz d’échappement ; et, - un moyen d’asservissement pour activer ou désactiver le moyen de commande en fonction d’un résultat d’une comparaison issue du moyen de comparaison et/ou en fonction au moins d’un deuxième résultat issu d’une relation prédéfinie entre la température du dispositif de traitement et la température des gaz d’échappement.The invention relates to a control assembly, and a method for implementing, an automatic engine start-stop system provided as a drive source for a vehicle, the assembly comprising: - a means of control of the automatic start-stop system actuated as a function of driving conditions of said vehicle, - first and second determining means for determining a temperature of the treatment device and a temperature of the exhaust gases, - a comparison means for comparing the temperature of the processing device with a first predefined value, - a second determining means for determining a temperature of the exhaust gases; and, - a control means for activating or deactivating the control means according to a result of a comparison resulting from the comparison means and/or according to at least a second result resulting from a predefined relation between the temperature of the treatment device and the temperature of the exhaust gases.
