摘要:

PROBLEM TO BE SOLVED: To evaluate tire performance more accurately by using biological information about a crew.

SOLUTION: An apparatus 1 for evaluating tire performance includes an apparatus body 10 and a signal acquisition unit 20. The signal acquisition unit 20 acquires an electrical signal from an electrode attached to the frontal pole Fp1 of a crew 3 according to International Law 10-20. The apparatus body 10 includes: a signal input unit 11 that is supplied with the electrical signal acquired by the signal acquisition unit 20 an analysis unit 12 that analyzes the electrical signal supplied to the signal input unit 11 and a display unit 13 that displays results of the analysis of the electrical signal by the analysis unit 12. The analysis unit 12 performs a temporal frequency analysis of the electrical signal in accordance with a period of time elapsed since the point of time when operation started, and executes an multivariate analysis of a frequency component of the electrical signal as obtained by the temporal frequency analysis. The analysis unit 12 includes a frequency analysis computing unit 121 and a factor analysis computing unit 122.
