Abstract

Provided are a device for controlling an electric vehicle and a method of controlling an electric vehicle that are capable of appropriately suppressing a vibration. In the device for controlling an electric vehicle according to the present invention, when a motor configured to generate a torque for braking or driving a drive wheel is controlled based on a torque command value based on an accelerator operation or a brake operation by a driver and a vibration suppression control torque command value for suppressing a vibration component caused by a resonance of the vehicle, the vibration suppression control torque command value is restricted based on a state of the drive wheel during a travel.
