摘要
In order to provide a method and an apparatus for accurately estimating the grounding shape of a tire during traveling, an acceleration sensor provided on a knuckle is provided with a pair of shoulder land portions 24a,A, PB) Of the tire 20 on which the sip columns 25A and 25B are arranged is detected and a rotation order spectrum is obtained by analyzing the order of rotation,A) Corresponding to the rotational order nA) Peak height (ZA), A period (PB) Corresponding to the rotational order nB) Peak height (ZB) Is extracted, and the peak height (ZA) And the threshold value KA) And peak height (ZB) And the threshold value KB) To compare the tire grounding shape (FA) Of the ground (LA), And estimates whether or not the tire grounding shape (FB) Of the ground (LB) Is estimated to be shorter than the predetermined threshold value.
