Abstract
A lane-keeping system suitable for use on an automated vehicle includes a camera, a ranging-sensor, and a controller. The camera is used to capture an image of a roadway traveled by a vehicle. The ranging-sensor is used to detect a reflected-signal reflected by an object proximate to the roadway. The controller is in communication with the camera and the ranging-sensor. The controller is configured to determine a lane-position for the vehicle based on a lane-marking of the roadway. The controller is also configured to determine an offset-distance of the object relative to the lane-position based on the reflected-signal. The controller is also configured to operate the vehicle in accordance with the lane-position when the lane-marking is detected, and operate in accordance with the offset-distance when the lane-marking is not present.
