Control device

A control device that controls a vehicle drive device including an input member drivably coupled to a drive force source including a rotary electric machine and an internal combustion engine, an output member drivably coupled to wheels, and a speed change mechanism that transfers rotation of the input member to the output member with a speed of the rotation changed in accordance with a speed ratio of a shift speed selected from a plurality of shift speeds that can be established switchably, wherein

• when switching between the shift speeds, a rotation-varying torque command value, which is a command value for torque that the drive force source is caused to output to vary the rotational speed of the input member, is calculated, the rotary electric machine is caused to output torque in accordance with the rotation-varying torque command value, and in the case where it is determined that an absolute value of the torque that the rotary electric machine is caused to output will become more than a predetermined threshold, both the rotary electric machine and the internal combustion engine are caused to output torque corresponding to the rotation-varying torque command value such that the output torque of the rotary electric machine becomes equal to or less than the predetermined threshold.
