摘要： PROBLEM TO BE SOLVED: To determine dynamic characteristics of a tire which can be achieved as request characteristics of the tire in the design of a vehicle. SOLUTION: The values of parameters when the longitudinal force and lateral force of the tire and the characteristic curve of self-aligned torque are approximated by "Magic Formula" are applied to a vehicle model, and simulation is carried out for performance evaluation. When predetermined performance is not satisfied by the vehicle model, the simulation is carried out by correcting the values of the parameters for the performance evaluation of the vehicle, and the characteristic curve of the tire to be specified by the values of the corrected parameters of "Magic Formula" is calculated, and values of tire dynamic element parameters are derived on the basis of the tire dynamics model from the characteristic curve. In the tire dynamic model, a center position on a ground surface is moved in accordance with the generated longitudinal force when a slip ratio in a brake direction is imparted. When the predetermined performance is satisfied by the vehicle model (S612), the values of the tire dynamics element parameters corresponding to the parameters of "Magic Formula" are decided as being the tire request characteristics (S622).

摘要： 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.
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.
