Claim:
1. A lane departure prevention control system for a vehicle comprising: a lane detector that detects a lane on which the vehicle travels; a disturbance information detector that detects information on disturbance applied to the vehicle; a correction module that corrects position information of a departure determination line used for determining whether the vehicle departs from the lane, based on at least the information on the disturbance applied to the vehicle; a departure predictor that make a prediction of departure from the lane, based on position information on the departure determination line and a travelling state, the position information corrected by the correction module; a target turn amount calculator that calculates a target turn amount to be applied to the vehicle, required for preventing departure from the lane based on the prediction of the departure from the lane; and a target turn amount generator that generates the target turn amount to the vehicle, wherein the information on the disturbance detected by the disturbance information detector includes a cant angle of the lane, and when there is a possibility that the vehicle may depart from the lane in an upward direction of a cant, the correction module corrects the position of the departure determination line from which the vehicle departs, toward an outer side of a lane mark line and corrects the target turn amount calculated by the target turn amount calculator so as to decrease, and when there is a possibility that the vehicle may depart from the lane in a downward direction of the cant, the correction module corrects the position of the departure determination line from which the vehicle departs, toward a center of the lane and corrects the target turn amount calculated by the target turn amount calculator so as to increase.
