Method for managing the excitation of an automobile alternator by means of a regulator
First Claim
1. A method of managing an excitation of an alternator of an automobile with a regulator of the automobile, the regulator delivering to an inductor of the alternator a pulse width modulation excitation signal,wherein the regulator receives, from an external management unit, a pulse width modulation excitation control signal with a frequency less than the excitation signal,the regulator delivers an excitation signal with a pre-programmed cycle ratio of a duration to enable the regulator to determine control information carried by the signal emitted by the management unit, andthe regulator continues the excitation signal with the pre-proprammed cycle ratio until receipt of instruction from the management unit to regulate the battery voltage.

Abstract
A system and method are provided to manage the excitation of an automobile alternator through the use of its regulator which delivers to the inductor of the alternator a pulse width modulation excitation signal. The regulator receives, from an external management unit, a pulse width modulation excitation control signal with a frequency less than that of the excitation signal. The regulator delivers an excitation signal with a pre-programmed cycle ratio for a sufficient duration to enable the regulator to determine the control information carried by the control signal from the management unit. The regulator continues the excitation signal with the pre-programmed cycle ratio until receipt of instruction from the management unit to regulate the battery voltage.
