METHOD AND DEVICE FOR MEASURING ROLLING RESISTANCE OF TIRE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for measuring a rolling resistance of a tire allowing for significant reduction in time required for measurement preparation and measurement.SOLUTION: The method for measuring a rolling resistance of a tire according to the present invention includes: a measurement step (Step S1) of measuring, while the tire is in contact with a body of rotation, a temporal change of the temperature of the tire and the temporal change of a rolling resistance value of the tire during a predetermined first time period; a final temperature prediction step (Step S2) of predicting a final temperature which the tire reaches when a predetermined second time longer than the first time elapses from contacting the tire contact the body of rotation; and a rolling resistance value prediction step (Step 3) of predicting a rolling resistance value of the tire at the final temperature based on the measured temporal change of the temperature and the measured temporal change of the rolling resistance value of the tire. A device 10 for measuring the rolling resistance value of the tire according to the present invention performs the method for measuring the rolling resistance of the tire.SELECTED DRAWING: Figure 2
