A method is described for the automatic management of the energy autonomy of a vehicle, and includes receiving a signal for indicating a distance and/or a path to cover, and dividing the distance and/or the path into space intervals; calculating an allowable variation of energy capacity in a space interval based on energy capacity detected by the sensors and on variation laws of the energy capacity; determining limit conditions for the speed and/or acceleration of the vehicle, on the basis of a map, chosen among a plurality of maps of speed-acceleration-variation of energy capacity; generating a regulated instantaneous torque request on the basis of the speed and/or acceleration detected by the plurality of sensors, of the determined limit conditions for the speed and/or acceleration and of the instantaneous torque request generated by the first central control unit. An electronic system capable of implementing such a method is described.
