The goal is to develop fundamental nonlinear filtering and estimation methods with applications to speed estimation in wheel based vehicles.
By analyzing the time-varying spectrum of the vibrations caused by the wheel, the wheel speed can be computed. Another potential application is to support IoT devices where speed information is needed when located on a vehicle. Here, wired solutions to the existing sensors can be excluded. Speed estimation in cellphones is one further application.
This project has developed algorithms tailored to this problem that extend current theory in nonlinear filtering.
