An electrified vehicle includes a motor including a plurality of windings, a first inverter connected to a first end of each of the plurality of windings and configured to drive the motor, a second inverter connected to a second end of each of the plurality of windings and configured to drive the motor in a second driving mode of a first driving mode and the second driving mode, a first controller configured to determine one of first and second output limit lines as an output limit line of the first driving mode, depending on whether a preset condition is satisfied, and a second controller configured to bidirectionally switch the first driving mode and the second driving mode within an operating point range according to the output limit line of the first driving mode in accordance with a value of a torque command for the motor and counter magnetic flux of the motor.

Electrified vehicle and method of controlling same

A motor driving system and a method of controlling same can protect a user by converting a driving mode into a dual inverter driving mode so that a vehicle can keep being driven when a transfer switching unit breaks down while the motor is operated in a Y-connection single inverter driving mode.
