Abstract: 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.

Abstract: A method of calculating forces acting on the footprint area of a tire, the tire being mounted on a wheel in turn mounted on a hub for engagement with a vehicle, the tire being moved along a longitudinal direction substantially parallel to the ground, includes the following steps: detecting a first angular position of the footprint area; detecting a second angular position of a reference point substantially integral with the hub; comparing the first and second angular positions with each other to determine a phase displacement between the reference point and footprint area; determining a parameter representing an angular velocity of the wheel; calculating at least one longitudinal force in the footprint function of at least the phase displacement and the parameter. Also described is an apparatus for calculating the forces.
