A lane-keeping system (10) suitable for use on an automated vehicle (12) includes a camera (32), an inertial-measurement-unit (40), and a controller (28). The camera (32) is configured to detect a lane-marking (38) of a roadway (36) traveled by a vehicle (12). The inertial-measurement-unit (40) is configured to determine relative-motion (42) of the vehicle (12). The controller (28) is in communication with the camera (32) and the inertial-measurement-unit (40). When the lane-marking (38) is detected the controller (28) is configured to steer the vehicle (12) towards a centerline (48) of the roadway (36) based on a last-position (54), and determine an offset-vector (58) indicative of motion of the vehicle (12) relative to the centerline (48) of the roadway (36). When the lane-marking (38) is not detected the controller (28) is configured to: determine an offset-position (60) relative to the last-position (54) based on information from the inertial-measurement-unit (40), determine a correction-vector (62) used to steer the vehicle (12) from the offset-position (60) towards the centerline (48) of the roadway (36) based on the last-position (54) and the offset-vector (58), and steer the vehicle (12) according to the correction-vector (62).
