摘要

PROBLEM TO BE SOLVED: To relate a value of a tire dynamic element parameter to a value of a transient response parameter of a response function used for calculating transient response data, by reducing deviation between measurement data of the transient response data and prediction data of the transient response data calculated by using a tire dynamic model, when calculating the tire transient response data or calculating the value of the tire transient response parameter.SOLUTION: The value of the transient response parameter is imparted to a high-order delay response function to a slip angle of lateral force acting on a tire rotary shaft, that is, the response function determined by using the tire dynamic model for reproducing a deformation response of the tire in cornering, an integral is performed by using the response function imparted with the value and time series data of the slip angle used as a tire measuring condition, and the time series data of the lateral force is calculated as the tire prediction data. In that case, the response function is constituted by setting a delay response of bending deformation of a belt member of the tire as a delay response by a useless time.
