Abstract: A method is described for determining the state of a vehicle equipped with an electric charge accumulator assembly adapted to power at least one starter device of a thermal engine and/or accessory devices of the vehicle and rechargeable by means of the kinetic energy of said engine, including the detection of the voltage available across the electric charge accumulator assembly of the vehicle in a predetermined succession of moments in time; at least one binary classification of the voltage value available across the accumulator assembly by comparison with a reference voltage value; and the determination of the operating state of the vehicle as a function of the outcome of the binary classification of the value of the voltage available across the accumulator assembly.

Abstract: A calibration method of the positioning of an onboard device of a vehicle with axes (x, y, z), wherein the device comprises at least one accelerometric sensor (S) which detects the accelerations to which the vehicle is subjected along axes (x?, y?, z?), angularly arranged with respect to the axes (x, y, z) of the vehicle with rotation angles (?x, ?y, ?z). The accelerometric sensor (S) acquires the acceleration values generated by the force of gravity G acting on the vehicle when the vehicle is stopped. A transformation matrix (R) is determined, wherein a first rotation angle (?x) and a second rotation angle (?y) are derived on the basis of acceleration values of the force of gravity detected along the axes (x?, y?, z?) when the vehicle is stopped, and a third rotation angle (?z) is derived on the basis of the determined travel direction of the vehicle.
