The invention relates to a method, system, vehicle, and computer program product for gear shifting in a hybrid powertrain, that comprises an internal combustion engine; an electric machine; a gearbox; and an energy storage unit connected to the electric machine, and at least one control unit arranged in communication with the internal combustion engine, the electric machine, the gearbox and the energy storage unit. The method comprises the steps of: determining an energy level in the energy storage unit; determining an acceleration ability with a subsequent gear; determining a target engine speed for the internal combustion engine based on the energy level in the energy storage unit and the acceleration ability; and controlling the gear shifting based on the target engine speed.
