A vehicle includes a pair of inverters coupled with an electric machine having a rotor. The vehicle includes a controller configured to alter pulse width modulation signals for the commands based on a back electromotive force estimate associated with the commands becoming different to reduce the amount. The alteration is responsive to voltage commands of respective phases of the pair becoming different while a target rotor speed associated with the commands differs from an actual rotor speed by an amount.
