Beschreibung
Zusammenfassung:	The present invention relates to a method for supply of additive to a catalytic exhaust cleaning process for cleaning of an exhaust flow from a combustion engine of a vehicle, which vehicle comprises control means for control of supply of said additive to said exhaust flow. The method comprises estimating an expected temperature situation for said exhaust cleaning process on the basis of a representation of the vehicle's running surface, and controlling said supply of additive on the basis of said estimated temperature situation.
