Methods and systems are provided for control of a combustion engine in a vehicle. In operation, at least one future speed profile for an actual speed of the vehicle is simulated during a road section ahead based on information about the road section and on knowledge that coasting with the combustion engine shut down will be applied during the road section. Subsequently, based on the future speed profile, a starting point in time is determined, when the combustion engine will need to be started for forward driving the vehicle and/or to brake the vehicle. Subsequently, a starting point brought forward in time is determined based on the need for a forward driving or braking force arising, where the starting point brought forward in time precedes the starting point in time. Subsequently, the combustion engine is controlled to be started at the starting point brought forward in time.
