Method and system for controlling stepwise charging of automotive alternator, and automotive alternator comprising this type of system

摘要

The method according to the invention comprises the step of the current duty cycle (DC) of the alternator excitation signal (7) from the initial duty cycle to the predicted duty cycle (EpsU) calculated by the alternator control loop (1, 5, 6). Including limiting the charging of the automotive alternator by allowing only a modest increase. In accordance with the present invention, the complementary limitation of alternator charging is dependent on the current duty cycle (DC) depending on at least one parameter of the heat engine, including angular acceleration (mot) and / or heat motor rotational speed (Nmot). ) To limit the increase. In particular, this complementary limitation may further include limiting the current duty cycle (DC) increase in response to a negative value of angular acceleration (mot).
