Abstract

L'invention concerne un procédé de commande (1) d'un organe de chauffage d'une sonde à oxygène pour un véhicule automobile à moteur thermique, ledit procédé comprenant- une étape de régulation (12b) par paliers de la puissance de chauffe dudit organe de chauffage en fonction dudit profil de régulation fourni ; une étape de détection (20) de la disponibilité d'un signal de mesure d'oxygène de ladite sonde ; et lorsque qu'un signal disponible est détecté, une étape de régulation stabilisée (15) de la puissance de chauffe dudit organe de chauffage à une valeur de puissance de chauffe stabilisée constante.The invention relates to a method for controlling (1) a heating element of an oxygen sensor for a motor vehicle with an internal combustion engine, said method comprising - a step of regulation (12b) in stages of the heating power of said heating device according to said regulation profile provided; a step of detecting (20) the availability of an oxygen measurement signal from said probe; and when an available signal is detected, a stabilized regulation step (15) of the heating power of said heating member at a constant stabilized heating power value.
