In order to achieve the intended vehicle body vibration-damping control regardless of the responsiveness of an actuator that controls the drive torque, this vehicle body vibration-damping control device is equipped with: a vehicle body vibration estimation unit (205) that estimates the above-suspension behavior of the vehicle body on the basis of input information during driving; and a torque command value calculation unit (206) that calculates a correction torque value for correcting a drive torque command value applied to an engine (106) when the above-suspension behavior is controlled. The torque command value calculation unit (206) has: regulator and tuning units (308, 309, 310) that calculate a correction torque value on the basis of the estimation result for the above-suspension behavior; and a nonlinear gain amplification unit (313) that amplifies the absolute value of the correction torque when the sign of the calculated correction torque value is in a region wherein the value switches between positive and negative, and that uses this amplified value to correct the drive torque command value. |
