Abstract
The invention provides to a method for controlling a vehicle () with an internal combustion engine () and a transmission (), the transmission being arranged to automatically provide shifts between a plurality of gear ratios between the engine and at least one driven wheel () of the vehicle, characterized by the steps of: —registering (S, S) a decrease of a demanded torque from an engine control input device () of the vehicle, —controlling (S, S) in response to the demanded torque decrease the rotational speed of the engine so as to not be below a rotational speed threshold value which is above an idle speed of the engine, and where said rotational speed threshold value is determined so as for a transmission gear down shift to be avoided.
