  "textContent": "A vehicle vibration control device (100) includes: a motor generator (50) connected via a motor shaft (51) to a power transmission path between a crankshaft (11) of an engine (10) and a drive axle (201) that transmits a drive torque to a tire; and a motor generator control portion (60) executing control of an output torque which is actually output by the motor generator. The motor generator control portion includes a damper torque calculation section (61) that acquires information on a crank angle and a motor angle to calculate a damper torque generated by a damper (20), an explosion cycle calculation section (62), a reverse phase torque calculation section (63), a delay time calculation section (64), a compensation time calculation section (65), a first compensation time calculation section (66), a torque correction amount calculation section (67), and a command output section (68).",
