ALIGNMENT OF MULTIPLE DIGITAL MAPS USED IN A VEHICLE

A navigation system (10) for an automated vehicle includes an object-detector (18), a first-map (24), a second-map (30), and a controller (36). The object-detector (18) indicates relative-positions (20) of a plurality of objects (22) proximate to the host-vehicle (12). The first-map (24) indicates a first-object (26) and a second-object (28) detected by the object-detector (18). The second-map (30) is different from the first-map (24). The second-map (30) indicates the first-object (26) and the second-object (28). The controller (36) is in communication with the object-detector (18), the first-map (24), and the second-map (30). The controller (36) is configured to determine a first-coordinate (40) of the host-vehicle (12) on the first-map (24) based on the relative-positions (20) of the first-object (26) and the second-object (28), determine a second-coordinate (50) of the host-vehicle (12) on the second-map (30) based on the relative-positions (20) of the first-object (26) and the second-object (28), and align the first-map (24) and the second-map (30) based on the first-coordinate (40), the second-coordinate (50), and the relative-positions (20) of the first-object (26) and the second-object (28).
