The present invention relates to an apparatus and a method for lane keeping control. The apparatus for lane keeping control comprises: a lane recognition unit which recognizes lanes from forward-looking lane images captured by a forward camera and recognizes a tracking line of a beam pattern projected on the ground surface of a road; a calculation unit which computes a virtual center lane based on the recognized lane and computes a virtual center tracking line based on the recognized tracking line, and calculates an error between the virtual center lane and the virtual center tracking line; an error correction unit which corrects lane information based on the error between the virtual center lane and the virtual center tracking line; and a control unit which performs lane-keeping control based on the corrected lane information. Therefore, the apparatus and the method for lane keeping control can prevent a vehicle from drifting and allow the vehicle to follow the center of the lane while driving.
