LANE KEEPING CONTROL METHOD

Disclosed is a lane keeping control system (1), including: a target distance calculator (100) configured to calculate a target distance (L) by receiving a speed of a vehicle; and a target trace generator (200) configured to generate coordinates of a target point separated by the target distance (L) by receiving vehicle information and camera image information and generate a target trace to the target point as a circular trace. Accordingly, by variably calculating a target distance according to a speed of a vehicle, generating a target trace of a vehicle according to the target distance as a profile (curvature) in a form of a circular trace, and applying the generated profile (curvature) to a lane keeping control, smooth lane keeping control may be achieved and a sense of steering difference of a driver may be minimized.
