    Abstract: 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.

    Abstract: Methods and systems are described for establishing high-accuracy absolute landmarks that can be used to locate a vehicle's location during a vehicle/HAAL interaction event in some embodiments. Comparing that information with GNSS satellite data allows GNSS satellite errors to be determined and either used by a first vehicle and/or conveyed to other vehicles in the region in some embodiments. Methods and systems are also described for obtaining effectively continuous values of intermittently measured road surface parameters that are determined over time by discrete measurements by systems in a plurality of vehicles in some embodiments.

    Abstract: Methods related to the control of vehicle systems while a vehicle is traveling along a road surface are disclosed. In some implementations, data related to the road surface ahead of the vehicle is separated into first and second frequency ranges. Commands for a vehicle system may then be determined for the different frequency ranges and the vehicle system may be controlled based at least in part on the separate commands for the separate frequency ranges. This may include determining a combined system command based at least in part on the separate commands for the separate frequency ranges in some implementations.

    Abstract: Combination reactive-proactive controllers and their use are described herein. In a first mode of operation, such controllers may rely simultaneously both a priori information about a road surface ahead of the vehicle obtained from a data base and real time information collected by one or more on-board sensors. Alternatively, in a second mode, such controllers may rely only on real time information collected by one or more on-board sensors. Systems controlled by such controllers may include, but are not limited to, active suspension actuators.
