Abstract: Embodiments related to methods and systems for localizing a vehicle on a road surface are described. In some embodiments, linked reference landmarks present on the road surface may be used to determine a location of a vehicle on the road surface and/or to predict a path of travel of the vehicle along the road surface.

Abstract: Systems and methods described herein include implementation of road surface-based localization techniques for advanced vehicle features and control methods including lane drift detection, passing guidance, bandwidth conservation and caching based on road data, vehicle speed correction, suspension and vehicle system performance tracking and control, road estimation calibration, and others. According to one aspect, the disclosure provides a method including obtaining, from one or more sensors corresponding to a left wheel of a vehicle, left wheel data as the vehicle traverses a road segment. The method also includes obtaining, from one or more sensors corresponding to a right wheel of a vehicle, right wheel data as the vehicle traverses the road segment.

Abstract: 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.

Abstract: A method of terrain-based localization of a vehicle is provided. The method may include determining the vehicle is within a threshold distance of a road segment end point and comparing a measured road profile to a reference road profile associated with the road segment. A method of identifying a track (e.g., a lane) of a road segment road profile is provided. The method may include determining if a number of stored road profiles exceeds a threshold number of road profiles and identifying one or more clusters in the stored road profiles if the threshold number is exceeded.

Abstract: In some embodiments, methods and systems may be used to control operation of various systems of the vehicle based on road features included in an upcoming portion of a road surface located along a path of travel of the vehicle. This control may either be based on a probability of encountering a road feature on the road surface 5 and/or frequency information related to the upcoming portion of the road surface.
