Abstract

A method for estimating a location of a center of gravity (CG) of a sprung mass of a vehicle includes steps of a) determining whether the vehicle is stationary or moving; b) if the vehicle is stationary, calculating estimated x and y coordinates of the CG; c) storing the estimated coordinates in memory; and d) repeating steps a)-c) until the vehicle is no longer stationary.
