1. A pre-active safety seat system for a vehicle, the pre-active safety seat system comprising:
a vehicle environment sensor configured for detecting risk collision situation information for a neighboring vehicle while the vehicle travels;
a multi-seat sensor configured for detecting at least one of a recline angle, a slide movement position, and a cushion tilt angle of a seat as a current seat posture of the seat in the vehicle;
a multi-seat motor coupled to the seat and configured for generating a motor driving force and applying the motor driving force to the seat so that the current seat posture of the seat is changed into a seat target posture by changing at least one of the recline angle, the slide movement position, and the cushion tilt angle of the seat; and
a controller electrically connected to the vehicle environment sensor, the multi-seat sensor and the multi-seat motor and configured for controlling the motor driving force to adjust the current seat posture of the seat up to the seat target posture in a risk collision situation confirmed by the controller according to the risk collision situation information,
wherein the multi-seat sensor includes:
a recline sensor mounted on a seatback of the seat to detect the recline angle; and
a slide sensor mounted on a seat cushion of the seat to detect the slide movement position of the seat cushion, and
wherein the controller is configured to simultaneously control the adjusting of the seatback angle and moving of the position of the seat cushion, thereby shortening a pre-active safety seat (PSS) required time of the seat target posture in a PSS operable section before collision of the vehicle from a risk detection.
