Zusammenfassung:The method involves controlling a supply voltage (Ubat) of an on-board network (4) of a vehicle to a set point (Uref) by a regulation loop unit. A sampled value (Us) of the supply voltage is digitally acquired by a digital acquisition unit (7). A variable pulse width excitation signal (9) is controlled for controlling excitation current (I-EXC) flowing through a winding of an alternator (3). Variations of the sampled value between a lower threshold and an upper threshold around a mean value of the sampled value are limited. An independent claim is also included for a system for regulating an alternator of a car.
