Online Center of Gravity Estimation in Automotive Vehicles using Multiple Models and Switching

In this paper we present a methodology based on multiple models and switching for realtime estimation of center of gravity (CG) position in automotive vehicles. The method utilizes simple linear vehicle models and assumes availability of standard stock automotive sensors. We demonstrate the efficacy of our technique with numerical simulations. We also give a simple application example for implementing the idea in automotive vehicles as a switch for rollover controller activation.
