Abstract
Systems and methods described herein include implementation of road surface-based localization techniques for advanced vehicle features and control methods including confidence-based consumption, air suspension control systems and methods, end of travel management, road profile creation techniques, and others.
Claims11
A method of creating a road profile estimate, the method comprising:
- obtaining multiple datasets, each of the multiple datasets representing a road profile estimation for a road segment, the multiple datasets originating from either different vehicles, different sensor sets, or operation at different speeds, wherein the multiple datasets include data recorded at different spatial and/or temporal frequencies;
- determining a range of spatial frequencies where each of the multiple datasets have high fidelity;
- blending the multiple datasets into a single road profile estimate in a spatial frequency domain;
- and
- storing the single road profile estimate in a database.
