Method for controlling the progressive charge of an automobile alternator

The method involves determining maximum mechanical torque at which an alternator is deducted on a thermal engine of a motor vehicle. Maximum torque is determined according to speed of rotation of the alternator. Progressive charge is controlled by a progressive charge control unit comprising a progressive charge return signal indicating a maximum value at which excitation current is reached. The return signal is updated when excitation current attains a stabilized value so as to indicate a maximum current value of excitation current which is equal to the stabilized value. An independent claim is also included for an alternator comprising a stator.
