Abstract
The input/output characteristic estimation method for testing system comprises; first excitation measurement steps (S-S) in which an input obtained by superimposing an excitation input donto a second torque control input ibis input to a second dynamometer, and the frequency response idwith respect to the excitation input dis measured; second excitation measurement steps (S-S) in which input obtained by superimposing excitation input don third torque control input ibis input to a third dynamometer, and frequency response idwith respect to the excitation input dand the like are measured; and mechanical characteristic estimation steps (Sand S) in which the response measured in the first and second excitation measurement steps are used to estimate the transfer function Gt_iand the like from the second or third torque current command signals (ii) to the first or second axial torque detection signals (tor t).
