TIRE LOAD PREDICTION SYSTEM, TIRE LOAD PREDICTION PROGRAM, AND TIRE LOAD PREDICTION METHOD

A tire load prediction system of the present invention includes: a sensor unit SU; a strain data acquisition unit 202; a linear transformation unit 251 that performs a linear transformation on the strain data; a first estimation unit 252 that estimates a velocity and angular velocity in the tire tangential direction; a second estimation unit 253 that estimates a velocity in a tire radial direction from values of the velocity and angular velocity in the tire tangential direction; a third estimation unit 254 that estimates a velocity in a θ-angle direction from values of an acceleration and angular velocity in the tire tangential direction; a fourth estimation unit 255 that estimates deflection of the tire, the velocity in the tire radial direction, and the velocity in the θ-angle direction; and a load prediction unit 256 that predicts a load applied to the tire.
