Abstract
Official abstract text for this publication.
A lane-keeping system for an automated vehicle includes a lane-detector, an object-detector, and a controller. The lane-detector indicates which lane of a roadway is occupied by a host-vehicle. The object-detector detects objects proximate to the host-vehicle. The controller is in communication with the lane-detector and the object-detector. The controller is configured to operate the host-vehicle to follow a first-lane using the lane-detector when no object is detected by the object-detector in the first-lane that warrants a lane-change and no lane-change from the first-lane is initiated by an operator of the host-vehicle, and allow a lane-change to a second-lane when initiated by the operator. The controller is also configured to initiate a lane-change to the first-lane from the second-lane after a first-time-interval after the lane-change to the second-lane that was initiated by the operator when the first-lane is available for unimpeded travel by the host-vehicle for greater than a second-time-interval.
First claim
Opening claim text (preview).
We claim: 1 . A lane-keeping system for an automated vehicle, said system comprising: a lane-detector that indicates which lane of a roadway is occupied by a host-vehicle; an object-detector that detects objects proximate to the host-vehicle; and a controller in communication with the lane-detector and the object-detector, said controller configured to operate the host-vehicle to follow a first-lane using the lane-detector when no object is detected by the object-detector in the first-lane that warrants a lane-change, and no lane-change from the first-lane is initiated by an operator of the host-vehicle, allow a lane-change to a second-lane when initiated by the operator, initiate a lane-change to the first-lane from the second-lane after a first-time-interval after the lane-change to the second-lane that was initiated by the operator when the first-lane is available for unimpeded travel by the host-vehicle for greater than a second-time-interval. 2 . The system in accordance with claim 1 , wherein the controller is further configured to remain in the second-lane after the first-time-interval when a roadway-divergence is located within a predefined-distance of the host-vehicle and until the roadway-divergence is passed by the host-vehicle. 3 . The system in accordance with claim 1 , wherein the controller is further configured to remain in the second-lane for a third-time-interval when the operator overrides the lane-change to the first-lane from the second-lane that was initiated by the controller. 4 . The system in accordance with claim 3 , wherein the controller is further configured to remain in the second-lane after the third-time-interval when a roadway-divergence is located within a predefined-distance of the host-vehicle and until the roadway-divergence is passed by the host-vehicle. 5 . The system in accordance with claim 1 , wherein the controller is further configured to initiate a lane-change to the second-lane when an object is detected by the object-detector in the first-lane that warrants a lane-change, and remain in the first-lane for a fourth-time-interval when the operator overrides the lane-change to the second-lane that was initiated by the controller. 6 . The system in accordance with claim 5 , wherein the controller is further configured to remain in the first-lane after the fourth-time-interval when a roadway-divergence is located within a predefined-distance of the host-vehicle and until the roadway-divergence is passed by the host-vehicle.
