Control apparatus of vehicle for changing lane and control method of the same

Provided is a control apparatus of a vehicle for changing a lane, including: a target lane generator configured to generate a target lane; a target distance generator configured to generate a target distance; a circular trace generator configured to generate a circular trace passing a current point of a vehicle and a point on a center line of the target lane spaced by the target distance based on the vehicle, and having a driving direction of the vehicle as a tangential direction in real time; and a steering controller configured to calculate a target rate and a target steering angle so as for the vehicle to follow the generated circular trace, thereby providing an advantageous effect of preventing a sense of steering difference and a pulling phenomenon of the vehicle when changing a lane.
