PROCEDE DE COMMANDE D'UN ALTERNO-DEMARREUR AUTOPILOTE COMPORTANT UNE ETAPE ABREGEE DE PREFLUX

摘要

A method for controlling a self-piloted alternator-starter for starting or restarting the thermal engine of an automobile. The alternator-starter includes a rotor rotating in a stator, and a belt for transmitting the torque of the alternator-starter rotor to the crankshaft of the thermal engine. The method includes a first preflux step during which the rotor winding is excited by a preflux electric current, and a second starting step during which the stator windings are excited. The preflux step lasts from 10 to 100 ms so that the transmission belt is tensioned below a degradation tension at the start of the second starting step.
