Abstract

Le procédé selon l'invention assure la commande électrique d'un catalyseur de réduction catalytique sélective chauffé électriquement, dit eSCR, équipant un véhicule à moteur thermique et comporte une commande en température du catalyseur eSCR. Conformément à l'invention, le procédé comprend une vérification (11, F1, F2) de conditions préalables de disponibilité de ressources énergétiques dans le véhicule, et une autorisation (F3) d'une activation électrique du catalyseur eSCR qui est dépendante d'un résultat de la vérification de conditions préalables, les conditions préalables (F10, F20, F21) étant prédéterminées de manière à respecter des contraintes imposées à un réseau d'alimentation électrique du véhicule.
