Abstract: A method for controlling the progressive charge of a motor vehicle alternator. The alternator comprises a stator, a rotor which is provided with an excitation coil, a voltage regulator which acts on an excitation current which is supplied to the excitation coil in order to regulate an output voltage of the alternator, and a device for controlling the progressive charge which, by means of limitation of the excitation current to a maximum value, determines a maximum mechanical torque which the alternator can collect on a thermal engine of the vehicle. The maximum mechanical torque is determined according to a speed of rotation (NALT) of the alternator, and the progressive charge control device comprises a so-called progressive charge return (PCR) signal which indicates the maximum value which the excitation current (lexc) can assume.

Abstract: A method to permit a start time of a heat engine of a vehicle to be controlled. The heat engine is mechanically coupled to a polyphase rotary electrical machine connected to an on-board electrical network. The method is of the type consisting of carrying out pre-fluxing by establishing an excitation current in the inductor for a predetermined pre-fluxing time (Tpref) before the phase currents are established. In accordance with the method, the predetermined pre-fluxing time (Tpref) is a function of the voltage (Vbat+X) of the on-board electrical network. Typically, the predetermined pre-fluxing time (Tpref) is increased when the voltage (Vbat+X) of the on-board electrical network reduces within a nominal voltage range (V 1, V2).
