Abstract: A method for improving startability of a vehicle is provided, the vehicle being provided with a prime mover and a kinetic energy recuperation system. The prime mover is adapted to propel the vehicle either alone or in combination with the kinetic energy recuperation system which is operably coupled to the prime mover and to wheels of the vehicle and is adapted to store energy at times when there is an abundance of energy and to use energy at times when there is a demand for energy. A vehicle is also provided.

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.
