Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a key unlocking system for a vehicle and a method thereof. More particularly, the present invention relates to a vehicle unlocking system for a vehicle, which can prevent a door from being locked without using a key while a driver holds the ignition key in the ignition key box. The present invention relates to a sensing door unlocking system and a method thereof.

The door locking device includes a door lock detector for detecting a locked state of four doors, a key insertion detector for detecting whether the ignition key is inserted into the ignition key box, Control means for generating a door unlock signal and an alarm signal in response to the key insertion signal; and four door lock actuators for switching the door lock state to the door unlock state in response to the door unlock signal.

As described above, according to the present invention, even if the door is locked in a state where the ignition key is accidentally inserted into the ignition key box, the door is automatically switched to the door unlock state and the alarm is generated to recognize the unlock state, It is possible to know that there is. Therefore, it is possible to prevent the door from being locked while the ignition key is plugged into the key box.
