Title: Method for deciding tire model, method for computing tire transient response data, method for designing tire, and method for evaluating tire
Inventor: MIYASHITA NAOSHI
IPC: G06F17/50
Filed: 2007-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To decide a tire model for reproducing a transient response of a tire from the data prepared by measuring transient responses of forward and backward force of the tire and compute transient response data from desired slip rates by using this model.  <P>SOLUTION: Time constant of first-order lag model of the tire is initially set, and a response function of first-order lag response is fixed. Convolution integration of the fixed response function of first-order lag response and amount of time change of time series data of set slip rates is performed to obtain an effective slip rate. A characteristic curve displaying actually measured values of forward and backward force for values of the effective slip rates is regressed into one smooth curve by least squares by using a curve function. The square residuals sum of the least squares regression curve and the actually measured characteristic curve at this time is obtained to correct time constant to minimize the square residuals sum. The time constant when the square residuals sum is the minimum is decided as the time constant of first-order lag response to decide the tire model. The forward and backward force for desired set slip rate is computed by using this tire model and the time constant.  <P>COPYRIGHT: (C)2009,JPO&INPIT
