A lane-keeping-assist system suitable for use on an automated vehicle includes a camera, a steering-actuator, and a controller. The camera detects a lane-marking of a travel-lane traveled by a host-vehicle. The steering-actuator controls a travel-direction of the host-vehicle. The controller is in communication with the camera and the steering-actuator. The controller determines a lane-width of the travel-lane and determines a centerline of the travel-lane based on the lane-marking. The controller further determines an offset-position of the host-vehicle within the travel-lane based on the lane-marking. The controller further determines a clearance between the host-vehicle and the lane-marking based on the offset-position. The controller further determines an adaptive-threshold based on the lane-width. The controller further determines that the host-vehicle is approaching the lane-marking when the clearance is less than the adaptive-threshold, and activates the steering-actuator to steer the host-vehicle toward the centerline of the travel-lane.
