1. A system for calculating x, y and z coordinates of a center of gravity (CG) of a vehicle having a plurality of wheels, the system comprising vehicle control means configured for:
- a) determining whether the vehicle is stationary or moving;
b) if the vehicle is stationary, calculating only estimated x and y coordinates of the x, y and z coordinates; and
c) if the vehicle is moving, calculating only a z-coordinate of the x, y and z coordinates.

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.

5. A vehicle control system configured for estimating a location of a center of gravity (CG) of a sprung mass of a vehicle, the system comprising vehicle control means configured for:
-
a) determining whether the vehicle is stationary or moving; b) if the vehicle is moving, determining a roll acceleration of the vehicle; c) if the roll acceleration is effectively non-zero, determining if the vehicle is in a turn; and d) if the vehicle is in a turn, calculating an estimated z-coordinate of the CG of the vehicle sprung mass. - View Dependent Claims (6, 8, 13, 14, 15)

9. A method for estimating values of coordinates of a location in space of a center of gravity (CG) of a vehicle, the method comprising steps of, by a vehicle control system:
-
a) determining whether the vehicle is stationary or moving; and b) responsive to the determination made in step (a), calculating values for only one of a first portion of the coordinates and a second portion of the coordinates, wherein coordinates in the second portion are different from coordinates in the first portion.
