  • Torque transfer system
    Patent number: 9242638
    Abstract: A first shaft has one end coupled to an engine. A damper has a spring coupled the other end of the first shaft. A second shaft has one end coupled to the spring. A third shaft rotates in correspondence to a final output shaft. A fourth shaft has one end coupled to a first rotary electric machine. A power split mechanism is provided among the second shaft, the third shaft and the fourth shaft and transfers torque among the second shaft, the third shaft and the fourth shaft. A control unit calculates a torque correction value for the rotary electric machine based on information indicating torsion angle of the damper and corrects the torque of the rotary electric machine based on a calculated torque correction value.
