Abstract
A system and method estimating a vehicle tire load identifies a change in vehicle loading condition by measuring vibration resonant frequency peaks (bounce mode and/or pitch mode) of the unsprung mass. Signals required include the chassis vertical acceleration and/or chassis pitch rate obtained from commercially available sensors mounted to the vehicle. An observer model receives the inertial signal(s) and generates a dynamic load estimation based upon observed frequency change in the sprung mass natural frequency.
