The method comprises: - determining (S10) preview information (100) of the vehicle operation based at least on an upcoming road event (110, 120, 130) and an engine operation (210, 220, 230) associated with the upcoming road event; - performing (S20), in response of the preview information, at least one of: - controlling (S40) the operation of the engine system by increasing (S50) reductant injection to meet an ammonia storage threshold level; - controlling (S42) the operation of the engine system by increasing (S52) 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 (S44) the operation of the engine system by decreasing (S54) the engine out NOx to increase the amount of engine out particles to meet a soot threshold level in the DPF.",
