The possibility of a tandem drive system combining two motors and a planetary gear train is being considered in response to the shift to EVs in the automotive industry. However, in order to take advantage of the ability to change drive conditions according to situations such as road conditions, it is necessary to clarify the torque characteristics of the planetary gear train during gear shifting. In this study, the effect of the moment of inertia of the ring gear on the torque fluctuation during gear shifting was examined through experiments and simulations of tandem drive of a planetary gear train.
