Abstract

A computer system comprising processing circuitry configured to:- determine predicted vehicle operational information for a vehicle including at least predicted travel route (110) for a vehicle (1), a predicted shutdown of a combustion engine (10) of the vehicle (1) along the predicted travel route (110), and a predicted subsequent re-start of the combustion engine (10),- determine the topography (120) of the predicted travel route (110) subsequent to the predicted re-start of the combustion engine (10),- determine a set ammonia storage level threshold of a selective catalytic reduction, SCR, catalyst (31, 32) arranged in an exhaust after treatment system (30) to the combustion engine (10) in response to the topography (120) of the predicted travel route (110) subsequent to the predicted combustion engine re-start,- control an injector (34a, 34b) of the exhaust after treatment system (30) to inject a predetermined amount of reductant achieving the set ammonia storage level threshold prior to shutdown of the combustion engine (10).
