Abstract: The present disclosure relates to an automatic lane change control of a vehicle is possible using a lane change control device including: a space recognition unit that detects a front object using a camera sensor of a vehicle, recognizes an empty space, and determines a target position, within the empty space on the basis of a lane modeling equation determined from a lateral offset, the vehicle's traveling velocity (V), and a lane change request time (t); a path generation unit that generates a path for moving from a current vehicle position to the target position; and a control unit that performs a lane change control that controls at least one of the vehicle's steering angle and a vehicle velocity such that the vehicle moves to the target position along the path.
