A Stochastic Approach to Online Vehicle State and Parameter Estimation, with Application to Inertia Estimation for Rollover Prevention and Battery Charge/Health Estimation

This report summarizes research conducted at Penn State, Virginia Tech, and West Virginia University on the development of algorithms based on the generalized polynomial chaos (gPC) expansion for the online estimation of automotive and transportation system parameters from experimental data. The authors used gPC estimation for determining the state of charge and state of health of a lithium-ion battery in real time, and also for the determination of road-vehicle inertial parameters in real time. The overarching goals in these two applications are to improve vehicle safety through better battery diagnostics and better inertia estimate-based rollover prevention. The authors performed experimental validation studies for both of these applications. Finally, the authors began exploring the application of gPC-based estimation for stochastic traffic flow models.
