  • Method for propelling a vehicle
    Patent number: 9707955
    Abstract: A method is provided for propelling a vehicle having a power-train including 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 including a powertrain limit curve which is adapted to where applicable to 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.
