In an electrified vehicle, a vibration damping control device performs vibration damping control for canceling or reducing, with the use of regenerative braking, a predetermined vibration component by monitoring the vibration component and controlling a generator control device depending on the vibration component. A system control device determines whether the vibration damping control is performable based on at least a charge status of a battery. An anti-lock braking system control device transmits a request signal to the system control device while performing anti-lock braking system control. The system control device transmits a command signal to the vibration damping control device when the vibration damping control is determined to be performable and the request signal is received from the anti-lock braking system control device. The vibration damping control device performs the vibration damping control when the command signal is received from the system control device.
