A method for controlling an energy overload in a hybrid vehicle system which comprises an electrical storage and an electric machine, including: - a first step activated by a first transition indicating an instantaneous speed value of the vehicle and a second transition indicating a detection of an energy overload demand, arranged to estimate a recovery potential as a function of the value indicated by the first transition; - a second step activated by a third transition indicating an absence of an energy overload demand, arranged to estimate a recharged energy in the electrical storage; - a third step activated following the first step, arranged to generate an energy limit able to be used for the energy overload as being equal to a sum of the recovery potential and of the recharged energy, characterized in that it includes: - a fourth step activated by a fourth transition indicating a detection of energy overload demand, arranged to calculate an energy accumulation expended as a function of a power expended during the overload; - a fifth step activated following the fourth step, arranged to generate a remaining energy value so as to limit the energy able to be used for the energy overload by subtracting the expended energy accumulation from the sum of the recovery potential and the recharged energy, and in that it includes: - a sixth step arranged to calculate a power able to be used as a function of the remaining energy, in which: - when the remaining energy is greater than a threshold, the power which is able to be used is maximum; - when the remaining energy is less than the threshold, the power which is able to be used is limited in a proportional manner to the remaining energy. - a first step activated by a first transition indicating an instantaneous speed value of the vehicle and a second transition indicating a detection of an energy overload demand, arranged to estimate a recovery potential as a function of the value indicated by the first transition; - a second step activated by a third transition indicating an absence of an energy overload demand, arranged to estimate a recharged energy in the electrical storage; - a third step activated following the first step, arranged to generate an energy limit able to be used for the energy overload as being equal to a sum of the recovery potential and of the recharged energy, - a fourth step activated by a fourth transition indicating a detection of energy overload demand, arranged to calculate an energy accumulation expended as a function of a power expended during the overload; - a fifth step activated following the fourth step, arranged to generate a remaining energy value so as to limit the energy able to be used for the energy overload by subtracting the expended energy accumulation from the sum of the recovery potential and the recharged energy, and in that it includes: - a sixth step arranged to calculate a power able to be used as a function of the remaining energy, in which: - when the remaining energy is greater than a threshold, the power which is able to be used is maximum; - when the remaining energy is less than the threshold, the power which is able to be used is limited in a proportional manner to the remaining energy. - a sixth step arranged to calculate a power able to be used as a function of the remaining energy, in which: - when the remaining energy is greater than a threshold, the power which is able to be used is maximum; - when the remaining energy is less than the threshold, the power which is able to be used is limited in a proportional manner to the remaining energy. - when the remaining energy is greater than a threshold, the power which is able to be used is maximum; - when the remaining energy is less than the threshold, the power which is able to be used is limited in a proportional manner to the remaining energy.
