Beschreibung
Zusammenfassung:	The present invention relates to a method for propelling a vehicle (100) comprising a first power source (101) being an internal combustion engine and a second power source (110) comprising at least one electrical machine. The vehicle (100) is configured to be selectively driven according to a first mode (M1) and a second mode (M2), where in said second mode (M2), providing power for propelling said vehicle (100) is prioritized more in relation to fuel efficiency of said vehicle (100) than in said first mode (M1). When a driver requests a maximum power for propelling said vehicle (100) power delivered by said first power source (101) and said second power source (110) is controlled such that the total power delivered by said first (101) and said second (110) power source exceeds the maximum deliverable power of said first power source (101). The total power delivered by said first (101) and said second (110) power source is allowed to exceed the maximum deliverable power of said first power source (101) only when said vehicle is being driven according to said second mode (M2).
