摘要： Methods and systems related to determining the ordering and/or positioning of travel lanes on a road segment are disclosed. In some embodiments, this may include obtaining and clustering road surface profiles associated with a road segment using, for example, a degree of similarity or other appropriate metric. A lateral offset or position of the clustered profiles may be used in determining the lane ordering and/or position. The resulting lane specific information may be used to determine a travel lane for a vehicle by comparing a current road-profile obtained from the vehicle and the road profile information associated with the different lanes. In other embodiments, a method and/or system for augmenting a global navigation satellite system (GNSS) signal may include using a raw GNSS signal and a GNSS location associated with terrain-based data to determine a lateral offset for use in determining a corrected GNSS location of the vehicle.

摘要： Localization systems, including road surface-based localization systems, are disclosed that may work in conjunction with less precise systems, such as GPS, to accurately locate a vehicle on a road segment. Methods and apparatus are disclosed for the identification and selection of landmarks, including road surface-based landmarks.

摘要： Systems and methods for determining the location of a vehicle are disclosed. In one embodiment, a method for localizing a vehicle includes driving over a first road segment, identifying by a first localization system a set of candidate road segments, obtaining vertical motion data while driving over the first road segment, comparing the obtained vertical motion data to reference vertical motion data associated with at least one candidate road segment, and identifying, based on the comparison, a location of the vehicle. The use of such localization methods and systems in coordination with various advanced vehicle systems such as, for example, active suspension systems or autonomous driving features, is contemplated.
