CONTROL DEVICE

There are provided: an input torque detection part configured to detect an input torque variation value; a first filter processing part configured to extract and obtain, from the input torque variation value, a post-first-filter variation value that varies with a specific variation period; a vibration reduction control part configured to calculate an opposite-phase torque variation value whose phase is opposite to a phase of the post-first-filter variation value, and execute vibration reduction processing; and a second filter processing part configured to extract and obtain, from the post-first-filter variation value, a post-second-filter variation value that varies with a period longer than the specific variation period. The vibration reduction control part is configured to cause the vibration reduction processing to be brought into a non-execution state based on the post-second-filter variation value.
