Abstract
A torque variation control device for a vehicle which has a motor providing rotational torque to a drive shaft of a vehicle, a motor control means controlling the motor based on drive torque, and a rotational velocity detection means detecting a rotational velocity of the drive shaft or a rotational shaft of the motor. The device has a feature that the device includes a torque variation detection means detecting a torque variation of the vehicle caused by a variation of the rotational velocity, and a compensation torque setting means setting compensation torque in an opposite phase relative to the torque variation.
