  • Patent number: 10730508
    Abstract: A vehicle is equipped with a torque sensor configured to detect a torque, and which is disposed between an internal combustion engine and a first switching device on a first transmission path. When the first switching device is switched from a disconnected state to a connected state, a control device calculates a torque difference between a target torque of the internal combustion engine corresponding to a specified point on the first transmission path, and a detected torque or the like detected by the torque sensor. Further, the control device generates in a first rotary electric machine or a second rotary electric machine a compensation torque that compensates for the torque difference.
