Tire suspension fusion system for estimation of tire deflection and tire load and method of estimating a tire load

摘要

A tire load estimation system for a vehicle is disclosed. The system (10) comprises at least one tire (12) supporting a vehicle (14); tire static load sensor means mounted to the one tire (12) for detecting a measured static tire load; tire static load estimating means for calculating an estimated tire static load based on the measured static tire load; tire deflection estimating means for estimating a tire vertical deflection; load variation estimating means for estimating a load variation by using tire vertical deflection information; and a tire load estimating means for estimating a substantially instantaneous load on the tire (12) based on the estimated static load and the estimated load variation. Also, a method of estimating a tire load for a vehicle (14) is disclosed.
