Title:
TIRE EVALUATION METHOD AND TIRE EVALUATION SYSTEM
Document Type and Number:
Japanese Patent JP2015202833
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To highly reliably evaluate a tire.SOLUTION: A tire evaluation method includes: a running step of causing a vehicle 51 mounted with pneumatic tires 53a, 53b to run at a constant ground speed along a preset running route; a sensory evaluation step of sensorily evaluating a steering feel obtained from a steering system 52 of the vehicle 51 in the running step; an acceleration measuring step of measuring the lateral acceleration generated in the vehicle 51 in the running step; a steering effort measuring step of measuring a steering effort in the steering system 52 of the vehicle 51 in the running step; a performance characteristic value acquiring step of acquiring a performance characteristic value at the time when the steering effort is null from the lateral acceleration and the litharge waveform of the steering effort measured in the steering effort measuring step; and a lateral spring constant setting step of setting a lateral spring constant in the single bodies of the pneumatic tires 53a, 53b corresponding to the optimal value of the performance characteristic value led from the relationship with the steering feel in the sensory evaluation step.
