Claim:
1. A method for propelling a vehicle having a powertrain comprising a primary power source accompanied with a primary power torque curve and a secondary power source accompanied with a secondary power torque curve, the primary power source being adapted to deliver a maximum torque output in relation to rotational speed according to the primary power torque curve and the secondary power source being adapted to deliver a maximum torque output in relation to rotational speed according to the secondary power torque curve, the vehicle being adapted to be propelled by either one of the primary power source and the secondary power source or by both together, the powertrain further comprising a powertrain limit curve which is adapted to where applicable restrict a current driver demand from a driver of the vehicle in relation to the primary power torque curve and the secondary power torque curve when propelling the vehicle, the method comprising when propelling the vehicle by both the primary power source and the secondary power source: determining a current driver demand, determining a current propulsion adaption condition for the vehicle, adjusting the powertrain limit curve according to a propulsion adaption torque factor depending on the current propulsion adaption condition, where applicable restricting the current driver demand according to the adjusted powertrain limit curve, and requesting, the powertrain to propel the vehicle according to the thus possibly restricted current driver demand.
