Abstract
A drive train bench system has two dynamometers that are connected in series to a specimen. The mechanical characteristics estimation method has: a first measurement step for measuring a response to a first excitation torque input signal when the first excitation torque input signal overlaps a first torque current command signal while a measurement control circuit controls the two dynamometers; a second measurement step for measuring a response to a second excitation torque input signal when the second excitation torque input signal overlaps a second torque current command signal while the measurement control circuit controls the two dynamometers; and a mechanical characteristics transfer function estimation step for using the results from the first and second measurement steps to estimate a mechanical characteristics transfer function.
