The invention relates to a method for reducing the energy of the torque for electrically boosting the acceleration of a hybrid vehicle provided with a power train including at least a heat engine and an electric machine capable of jointly or separately outputting a torque to the wheel in accordance with management laws (EML) optimising the energy consumption of the vehicle, and a traction battery which is capable of recovering all or part of the kinetic energy of the decelerating vehicle in the form of electric energy, and rechargeable via the heat engine. The method is characterised in that the electric boost torque available for the torque boost is reduced by a reduction coefficient (C) of 0 to 1 according to the amount of energy remaining in an energy range of the battery reserved for the torque boost.
