Patent ID: 8718854

Claim:
An electrically-powered vehicle comprising: a plurality of electric motors for generating a vehicle-driving force; a control device for controlling said plurality of electric motors; and an internal combustion engine, wherein said plurality of electric motors include: a first electric motor disposed on a power transmission path extending from said internal combustion engine to a drive wheel through a drive shaft; and a second electric motor mechanically connected to said drive shaft, said control device is configured to perform vibration-reduction control for reducing a periodic speed variation of the vehicle by: selecting, from said plurality of electric motors, an electric motor for use in performing said vibration-reduction control, depending on an operating state of said plurality of electric motors each; and selectively adding to an output torque of the selected electric motor among said plurality of electric motors, a compensation torque corresponding to a periodic vibration-reduction torque component for cancelling out a periodic speed variation component of the vehicle, and said control device performs said vibration-reduction control using said second electric motor when the operating state of said second electric motor is a state that allows said vibration-reduction control to be performed, and performs said vibration-reduction control using said first electric motor when the operating state of said second electric motor is not the state that allows said vibration-reduction control to be performed.
