A Bayesian approach to jointly estimate tire radii and vehicle trajectory

Emre Ozkan, Christian Lundquist, Fredrik Gustafsson
2011 2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)  
The novelty lies in a Bayesian approach to estimate online the time-varying radii and noise parameters using a marginalized particle filter, where no model approximations are needed such as in previously  ...  High-precision estimation of vehicle tire radii is considered, based on measurements on individual wheel speeds and absolute position from a global navigation satellite system (GNSS).  ...  The inference will be done by using marginalized particle filters [11] where the unknown noise parameters are marginalized out in relevant steps.  ...

Marginalized adaptive particle filtering for nonlinear models with unknown time-varying noise parameters

Emre Özkan, Václav Šmídl, Saikat Saha, Christian Lundquist, Fredrik Gustafsson
2013 Automatica  
For nonlinear models, we provide a Bayesian solution for the estimation of the noise distributions in the exponential family, leading to a marginalized adaptive particle filter (MAPF) where the noise parameters  ...  We illustrate the MAPF on first a standard example, and then on a tire radius estimation problem on real data.  ...  The true tire radii difference is calculated by computing the effective tire radii using the data collected during a long and straight segment of the road.  ...
