Abstract

PURPOSE: A method and system for controlling a vehicle door lock are provided to help passengers to safely alight from a vehicle by detecting a peripheral obstacle approaching from the rear side of the vehicle. CONSTITUTION: A peripheral obstacle detecting sensor(110) senses a peripheral obstacle of a vehicle. An alighting inclination detecting sensor(120) senses alighting inclination of a passenger of the vehicle. A door-lock actuator(150) opens and closes a door of the vehicle according to a control signal. An electronic control unit(140) transfers the control signal including a door opening command signal and a door opening prevention command signal to the door-lock actuator based on a sensing result of the peripheral obstacle.
