In order to simply and accurately calibrate crosstalk correction coefficients of a multi-component force detector provided in a rolling resistance testing machine, the present invention provides a method for calibrating a multi-component force detector provided in a rolling resistance testing machine (1) having a spindle shaft (5) on which a tire (T) is mounted, a running drum (3) with a simulated road surface (2) onto which the tire (T) is pressed, and a rotation torque meter (7) provided on a rotating shaft of the running drum (3). The method comprises calibrating the crosstalk correction coefficients, which are used for correcting the influence of crosstalk produced in the multi-component force detector, by using rolling test data incorporating a rotation torque measured by the rotation torque meter (7) and forces measured by the multi-component force detector, during a process of calculating forces acting on the tire (T) on the basis of measurement values from the multi-component force detector and by using the crosstalk correction coefficients. |
