Abstract

A Pre-Active Adjustment Safety control method includes: determining whether a possibility of collision exceeds a predetermined value based on sensing information received from at least one of a front sensor, a lateral sensor or a rear sensor; determining a position of a seat and an angle of a seat back when the possibility of collision exceeds the predetermined value; and controlling the seat to a predetermined state when at least one of the position of the seat or the angle of the seat back is not in the predetermined state.
