Abstract
A distribution differential gear mechanism includes a first rotation element drivingly connected to input member, a second rotation element drivingly connected to output member, and a third rotation element drivingly connected to rotary electric machine. When rotation speed difference between rotation speed of the second and first rotation elements become equal to or less than synchronization threshold due to an increase in rotation speed of output member, control device executes synchronization maintaining control of maintaining rotation speed difference at specified difference rotation that is set to be equal to or less than synchronization threshold, by performing a rotation speed control of rotary electric machine in conjunction with rotation speed of second rotation element and by causing internal combustion engine to output a target torque, and control device executes engagement control of transitioning second engagement device from released state to engagement state while synchronization maintaining control is being executed.
