An electrified vehicle system includes an electric motor coupled to a drive wheel via a plurality of power transmission components and a control device. The control device is configured to act as: a feedforward control section configured based on a transfer function simulating vibration transmission characteristics of a power transmission system, receiving as an input a required torque of the electric motor from a driver, and outputting a base command torque of the electric motor; a timing estimation section estimating, based on information on the power transmission system, a timing at which a backlash between the plurality of power transmission components is eliminated; and a torque correction section applying, to the base command torque, a correction torque for reducing a vibration generated in the power transmission system due to elimination of the backlash, in response to an arrival of the timing estimated by the timing estimation section.
