Abstract
(EN)
The present invention relates to a starting battery voltage recognition system and an external system off-state recognition method using same. More particularly, the present invention relates to a starting battery driving system and an external system off-state recognition method using same, in which an external system is recognized as being off-state in an overvoltage state, according to whether or not there is a difference between voltage values measured by two ADCs having different ground (GND) positions without a current sensor, to thereby enable the next starting of an engine.

La présente invention concerne un système de reconnaissance de tension de batterie de démarrage et un procédé de reconnaissance d'état de désactivation de système externe utilisant ce dernier. La présente invention concerne plus particulièrement un système d'entraînement de batterie de démarrage et un procédé de reconnaissance d'état de désactivation de système externe utilisant ce dernier, dans lequel un système externe est reconnu comme étant dans un état désactivé dans un état de surtension selon qu'il existe ou non une différence entre des valeurs de tension mesurées par deux CAN présentant des positions de masse (GND) différentes sans capteur de courant pour ainsi permettre le prochain démarrage d'un moteur.
