Abstract: The method according to the invention involves limiting the charging of a vehicle alternator by only authorizing progressive augmentation of a current duty cycle (DC) of an excitation signal (7) of the alternator from an initial duty cycle to an expected duty cycle (EpsU) calculated by a control loop (1, 5, 6) of the alternator. According to the invention, a complementary limitation of the charging of the alternator involves limiting the increase of the current duty cycle (DC) according to at least one parameter of the heat engine involving an angular acceleration (mot) and/or a rotation speed (Nmot) of the heat motor. In particular, this complementary limitation can additionally involve limiting the increase of the current duty cycle (DC) according to a negative value of the angular acceleration (mot).

Abstract: A method is disclosed to produce a supply voltage (B+) in an on-board system of a vehicle in response to an excitation current (I_ROTOR) applied to a rotor of the alternator. The method is of the type that consists in: limiting the resisting torque by determining a maximum cyclic ratio (DC_C_LIMIT) of the excitation current as a function of variables taken from a group containing a rotational speed (V_ROTOR) of the rotor, a temperature of the rotor, the excitation current and the supply voltage (B+). The maximum cyclic ratio is determined as a function of at least two of the variables in the group. According to one specific embodiment, the variables are rotational speed and temperature.
