Abstract

A method, performed by a control device, for starting a combustion engine during free-wheeling with engine off is described. The method comprises a step of controlling the clutch to a partially closed state, thereby starting the combustion engine; a step of controlling the clutch to an open state when the combustion engine has started, but prior to the output shaft of the combustion engine has reached a rotational speed synchronized with the rotational speed of the input shaft of the gearbox; and a step of synchronizing the speed of the combustion engine to the speed of the input shaft of the gearbox through control of fuel injection to the combustion engine.
