<p>A method of controlling operation of an energy system for a hybrid vehicle, the energy system including a combustion engine controlled to work at a desired engine rotational speed; an electric generator/motor driven by the combustion engine to output a generated electric power; a power consuming device driven by the combustion engine and drivable by the electric generator/motor; and an energy storage device connected to the electric generator/motor and arranged to receive the generated electric power output by the electric generator/motor. The method includes the steps of: monitoring an actual engine rotational speed; and if the actual engine rotational speed decreases from the desired engine rotational speed, controlling the electric generator/motor to output a gradually reducing generated electric power. Hereby, the combustion engine can be allowed to remain in an operating range where it works efficiently, while at the same time fulfilling the need for power of the power consuming device.</p> |
