Beschreibung
Zusammenfassung:	A module for controlling a rotary electric machine for a motor vehicle includes a calculating program, a value of the rotor coil voltage Vrot, a resistance value of the rotor coil Rrot, a value of the rotor coil induction Lrot. The program estimates the rotor coil current Irot according to this formula: Irot[k]=Irot[k−1]+(Vrot[k−1]−Irot[k−1]×Rrot)/Lrot×Ts in which Irot[k−1] is the estimate of the rotor coil current previously calculated at time k−1 and Ts is the sampling time between the index k−1 and the index k. To switch from a motor mode to a neutral mode, the control module is configured to control a shorting of the phases of the stator after the estimated rotor coil current Irot is equal to a predetermined value.
