TIRE UNIFORMITY IMPROVEMENT USING ESTIMATES BASED ON CONVOLUTION/DECONVOLUTION WITH MEASURED LATERAL FORCE VARIATION

摘要

Systems and methods for estimating a uniformity parameter of a tire are provided. For instance, convolution can be used to estimate radial force variation from one or more uniformity parameter measurements, including radial run out parameter measurements and lateral force variation measurements. Deconvolution can be used to estimate radial run out from one or more uniformity parameter measurements, including radial force variation parameter measurements and lateral force variation measurements. The estimated uniformity parameter can be estimated from the measured radial uniformity parameter using one or more models. The one or more models can represent an estimated radial uniformity parameter at a discrete measurement point as a weighted sum of the measured radial uniformity parameter at the discrete measurement point and one or more selected measurement points proximate the discrete measurement point. The measurement points can be selected based on the contact patch length of the tire.
