METHOD FOR CONTROLLING THE OPERATION OF AN ENGINE SYSTEM IN A VEHICLE

A method for controlling the operation of an engine system in a vehicle. The engine system including an engine and an exhaust aftertreatment system having an SCR catalyst and a DPF. The method includes determining preview information of the vehicle operation based at least on an upcoming road event and an engine operation associated with the upcoming road event; performing, in response of the preview information, at least one of: controlling the operation of the engine system by increasing reductant injection to meet an ammonia storage threshold level; controlling the operation of the engine system by increasing the engine out NOx to reduce the ammonia storage in the SCR catalyst to meet an ammonia slip threshold level in the SCR catalyst; controlling the operation of the engine system by decreasing the engine out NOx to increase the amount of engine out particles to meet a soot threshold level in the DPF.
