Abstract (en)
[origin: FR2746450A1] The interruption of supply to the starter is controlled by measuring the supply voltage to the motor. The measured supply voltage (Uf) is compared to the battery voltage (Uo) before starting commences. The measured voltage is compared to a threshold voltage that is a fraction (not greater than one) of the battery voltage before starting. The voltage before starting is stored, and used to provide a reference voltage that is a fraction of the starting voltage to a comparator. The comparator receives the measured voltage during starting at its other terminal, and delivers a signal to release the contactor when the measured voltage crosses the reference voltage.

Procédé pour la commande de la coupure d'un démarreur de véhicule automobile selon lequel on mesure la tension d'alimentation de ce démarreur et on coupe le démarreur lorsque cette tension atteint une valeur seuil (Uf), caractérisé en ce que cette valeur seuil est fonction de la valeur (U0) de la tension d'alimentation en début de démarrage. <IMAGE>
