METHOD FOR CONTROLLING A STOP AND AUTOMATIC RESTART DEVICE FOR A THERMAL ENGINE
First Claim
1. Control method for an automatic stop-and-start device for a heat engine of a vehicle comprising electrical energy storage means and a reversible alternator connected to the heat engine comprising:
- comparing the alternator temperature to a first predetermined temperature,detecting the appearance of at least one of the following two conditions relative to the electrical energy storage means;
a temperature less than a second predetermined temperature and a charge level less than a predetermined threshold, anddisabling the automatic engine restart if the alternator temperature is greater than the first predetermined temperature, and if at least one of said two conditions appears.

Abstract
The invention relates to a method for controlling a stop and automatic restart device for a thermal engine of a vehicle, comprising electric energy storage means and a reversible alternator connected to the thermal engine. The method comprises: comparing (16, 18) the temperature of the alternator (10) with a first predetermined temperature detecting (16, 18) the occurrence of at least one of the two following conditions concerning the electric energy storage means: a temperature (12) lower than a second predetermined temperature and a charge level (14) lower than a predetermined threshold; and if the alternator temperature is higher than the first predetermined temperature and if at least one of said two conditions occurs, inhibiting (26) the automatic restart of the engine.
