Claim Text:
1. A torque transfer system configured to transfer torque of an internal combustion engine and a rotary electric machine to a final output shaft, the torque transfer system comprising: a first shaft having one end coupled to the internal combustion engine configured to receive the torque of the engine; a resilient cushioning mechanism having a resilient deformable part coupled to an other end of the first shaft; a second shaft having one end coupled to the resilient deformable part; a third shaft rotatable in correspondence to the final output shaft; a fourth shaft having one end coupled to the rotary electric machine configured to receive the torque of the rotary electric machine; a gear part provided among an other end of the second shaft, one end of the third shaft and an other end of the forth shaft configured to transfer torque one another among the second shaft, the third shaft and the fourth shaft; and a control unit configured to control the torque of the rotary electric machine, wherein the control unit includes a torque correction value calculation part configured to calculate a torque correction value, which is a correction value for a torque of the rotary electric machine, based on information indicating torsion angle of the resilient cushioning mechanism, which is a relative angle between the first shaft and the second shaft, and wherein the control unit further includes a torque correction part configured to correct the torque of the rotary electric machine based on the torque correction value calculated by the torque correction value calculation part.
