Method and systems for the automatic control of the cutting off and restarting of the thermal engine of a vehicle during temporary immobilizations thereof

Method for controlling a thermal engine of a motor vehicle according to which said thermal engine is cut off and automatically restarted at a beginning and an end of temporary immobilization periods, according to which automatic cutting off of the thermal engine is inhibited when a vehicle battery is discharged below a given inhibition threshold, according to which the thermal engine is automatically restarted when the vehicle battery is discharged below said inhibition threshold, wherein a battery charge level is characterized by a vehicle battery voltage drop measured at the beginning of the last start-up of the starter motor.
