Abstract
A wheel information estimating apparatus, which includes: a detecting device for detecting a wheel motion state relating to a movement of a tired wheel of a motor vehicle; an estimating device for estimating wheel information relating to the tired wheel, on the basis of the wheel motion state detected by the detecting device; and a modifying device for modifying an element relating to estimation of the wheel information, so as to improve an accuracy of estimating the wheel information. The element to be modified is selected from a movement of a center of rotation of the tired wheel as viewed in a plane in which the wheel is rotated, a signal applied from the detecting device to the estimating device, and an internal parameter used by the estimating means for estimating the wheel information.
