Abstract

Un système de motorisation d'un véhicule comprend un moteur (1) thermique à allumage commandé et un dispositif de changement (3) de rapport de transmission de la puissance du moteur (1) au véhicule, et comporte un dispositif de traitement (2) des gaz d'échappement issus du moteur (1) comprenant un piège à oxydes d'azote et une unité de préconisation (5) de changement de rapport de transmission. Selon un procédé de commande, on pilote le système de motorisation pour contrôler les conditions de fonctionnement du piège à oxydes d'azote, en appliquant une loi spécifique à l'unité de préconisation (5) pour préconiser un éventuel changement de rapport de transmission lorsque le piège à oxydes d'azote doit être activé ou maintenu dans une étape de déstockage. Système de motorisation mettant en oeuvre le procédé.A motorization system of a vehicle comprises a thermal spark-ignition engine (1) and a device (3) for changing the transmission ratio of the power from the engine (1) to the vehicle, and comprises a processing device (2) exhaust gases from the engine (1) comprising a nitrogen oxide trap and a recommendation unit (5) for changing the transmission ratio. According to a control method, the motorization system is controlled to control the operating conditions of the nitrogen oxide trap, by applying a law specific to the recommendation unit (5) to recommend a possible change of transmission ratio when the nitrogen oxides trap must be activated or maintained in a destocking step. Motorization system implementing the method.
