Abstract
A vibration-suppression control device includes a processor calculating a rotation speed of a tire using an observer model including an observer model constant, and adding a damping torque, in which a gain adjustment corresponding to a gain constant is performed on a difference between the rotational speed of the tire and a rotational speed of the motor, to a torque of the motor. Further, the observer model constant is set in advance in a manner that the observer model constant in a state of during shifting is different from the observer model constant in a state of after shifting, and the processor uses the observer model, in which the observer model constant is switched between the state of during shifting and the state of after shifting.
