Abstract
A hybrid drive device having an input member drivingly coupled to an internal combustion engine. Control is performed so that motor torque output by the motor produces at least a part of inertia torque needed for rotation change of input-related members during the shifting. The control device limits the motor torque in an inertia phase during the shifting to a set value that has been set to or below a value having a smaller absolute value between values of performance limit torque of the motor at times before and after the shifting, sets a target input rotational speed of the input member during the shifting, and controls the engagement state of the friction engagement elements that control the rotation change of the input-related members in the inertia phase so as to generate the inertia torque calculated from the target input rotational speed in the input-related members.
