A method and a system for control of a combustion engine in a vehicle is presented. According to the present invention, at least one future speed profile vsin ICE off for an actual speed Vact of the vehicle is simulated during a road section ahead. The simulation is based on information about the road section and on knowledge that coasting with the combustion engine shut down will, at least initially, be applied during the road section. Subsequently, based at least on the at least one future speed profile vsin ICE off, starting point in time t ICE start is determined, when the combustion engine will need to be started because of a requirement for a forward driving force for the vehicle and/or a need to brake the vehicle. Subsequently, a starting point brought forward in time, t ICE pre_start, is determined, which precedes the starting point in time tICE start. Thus, according to the present invention, the starting point brought forward in time, tICE pre start, will occur before the starting point in time tICE start, which is determined based on the need for a forward driving or braking force arising. Subsequently, the combustion engine is controlled to be started at the starting point brought forward in time, tlCE_pre_start. |
