Abstract:
1. A method of controlling operation of an energy system for a hybrid vehicle, the energy system comprising: a combustion engine being controlled to work at a desired engine rotational speed; an electric generator/motor arranged to be driven by the combustion engine to output a generated electric power; a power consuming device arranged to be driven by the combustion engine and drivable by said electric generator/motor; and an energy storage device connected to said electric generator/motor and arranged to receive the generated electric power output by the electric generator/motor, wherein the method comprises the steps of: controlling said electric generator/motor to output generated electric power to said energy storage device; monitoring an actual engine rotational speed; and if the actual engine rotational speed decreases from said desired engine rotational speed, controlling said electric generator/motor to gradually reduce said generated electric power output to said energy storage device.
