Abstract
A navigation system for an automated vehicle includes an object-detector, a first-map, a second-map, and a controller. The object-detector indicates relative-positions of a plurality of objects proximate to the host-vehicle. The first-map indicates a first-object and a second-object detected by the object-detector. The second-map is different from the first-map. The second-map indicates the first-object and the second-object. The controller is in communication with the object-detector, the first-map, and the second-map. The controller is configured to determine a first-coordinate of the host-vehicle on the first-map based on the relative-positions of the first-object and the second-object, determine a second-coordinate of the host-vehicle on the second-map based on the relative-positions of the first-object and the second-object, and align the first-map and the second-map based on the first-coordinate, the second-coordinate, and the relative-positions of the first-object and the second-object.
