Abstract (en)

[origin: WO2013041793A1] The method according to the invention relates to monitoring the progressive charging of a vehicle alternator intended to be connected to a vehicle heat engine and capable of producing a supply voltage for a network onboard the vehicle. The method according to the invention involves limiting the charging of the alternator by only authorizing progressive augmentation of a current duty cycle (DC_EXC) of an excitation signal (7) of the alternator from an initial duty cycle to an expected duty cycle (DC_E) calculated by a control loop of the alternator. According to the invention, a spectrum of frequencies of the expected duty cycle (DC_E) is limited (filter 19) to a bandwidth of the control cycle.
