Publication number: 20240103531Abstract: 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.Type: ApplicationFiled: June 30, 2023Publication date: March 28, 2024Applicant: ClearMotion, Inc.Inventors: Vijayaraghavan Sridhar, John Parker Eisenmann, Yu Jiang, David Francis Weatherwax
