Abstract
A vehicle inertia and center of gravity estimator uses averaged displacement measurements to estimate changes in vehicle body mass, vehicle center of gravity location, and vehicle pitch moment of inertia, due to variations in fuel load, passenger load, and cargo load. The system is responsive to the acceleration of the vehicle for providing displacement readings, the mass of the vehicle, and the rotation of the vehicle to optimally adjust vehicle parameters. Variables used in estimating vehicle conditions include vehicle vertical displacement, vehicle ride height, vehicle mass, vehicle pitch moment of inertia, vehicle center of gravity location, and vehicle wheel base.
