摘要： A method creates determination spaces for determining a road surface state of a road surface on which a vehicle is running from output waveform data obtained by measuring changes in a physical quantity of a tire of the vehicle during the running using information regarding road surfaces and the output waveform data. The method includes obtaining the output waveform data in a plurality of different road surface states and a running condition at times of measurement of the output waveform data, classifying the output waveform data into a plurality of groups on a basis of the running condition, performing, for each group, machine learning using training data where the output waveform data is associated with information regarding the road surface states, and creating the determination space corresponding to the group.
