Torques and Vehicle State: an Automotive Application of Unknown Inputs Observer

Abstract : This paper describes how it is possible to estimate online the individual torques at each wheel of an automotivevehicle by using an unknown input observer together with avehicle model including the sprung mass pitch motion. The necessary measurements are the usual rotation speed plus the vertical load at the center of each wheel. This assumption anticipates the affordability of a new generation of wheel bearings with embedded measurements of transmitted forces. Successful simulated experimentations of the method are shown using a realistic simulator.
