Abstract
A vehicle includes an electric machine having independently selectable delta and wye windings. The electric machine has a lower torque producing limit with one of the windings than an other of the windings at a given speed. The vehicle includes a controller configured to select the other of the windings such that torque of the electric machine increases without increasing the given speed. The selection is responsive to operating with the one of the windings and a torque demand greater than the lower torque producing limit.
