METHOD FOR CONTROLLING AT LEAST A PART OF AN EXHAUST AFTER TREATMENT SYSTEM OF A VEHICLE

Abstract: a computer system comprising processing circuitry configured to: determine predicted vehicle operational information for a vehicle including at least predicted travel route for a vehicle, a predicted shutdown of a combustion engine of the vehicle along the predicted travel route, and a predicted subsequent re-start of the combustion engine; determine the topography of the predicted travel route subsequent to the predicted re-start of the combustion engine; determine a set ammonia storage level threshold of a selective catalytic reduction, scr, catalyst arranged in an exhaust after treatment system to the combustion engine in response to the topography of the predicted travel route subsequent to the predicted combustion engine re-start; and control an injector of the exhaust after treatment system to inject a predetermined amount of reductant achieving the set ammonia storage level threshold prior to shutdown of the combustion engine.
