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 () of the alternator from an initial duty cycle to an expected duty cycle (EpsU) calculated by a control loop () 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).
