Title (EN) METHOD AND SYSTEM PERTAINING TO CONTROL OF ADDITIVE SUPPLY IN A VEHICLE EXHAUST DISCHARGE SYSTEM
(FR) PROCÉDÉ ET SYSTÈME POUR COMMANDER UNE ALIMENTATION EN ADDITIF DANS UN SYSTÈME D'ÉVACUATION DES GAZ D'ÉCHAPPEMENT DE VÉHICULE
Abstract:
(EN) The present invention relates to a method for supply of additive to a catalytic exhaust cleaning process for cleaning of an exhaust flow from a combustion engine of a vehicle, which vehicle comprises control means for control of supply of said additive to said exhaust flow. The method comprises estimating an expected temperature situation for said exhaust cleaning process on the basis of a representation of the vehicle's running surface, and controlling said supply of additive on the basis of said estimated temperature situation.
(FR) La présente invention concerne un procédé d'alimentation en additif dans le cadre d'un processus d'épuration catalytique des gaz d'échappement pour épurer un flux d'échappement d'un moteur à combustion interne d'un véhicule, lequel véhicule comprend des moyens de commande pour commander l'alimentation en additif audit flux d'échappement. Le procédé consiste à évaluer une situation de température prévue pour le processus d'épuration des gaz d'échappement sur la base d'une représentation de la surface de roulement du véhicule, puis à commander l'alimentation en additif sur la base de la situation de température évaluée.
