A vehicle includes one or more inverter-fed electric machines such as permanent magnet synchronous motors. A controller operates an inverter in either six-step mode or PWM mode depending upon motor speed, motor torque, and the inverter input voltage. A method of selecting the operating mode may determine a transition threshold based on the ratio of rotor speed to inverter input voltage, reducing the approximation error associated with multi-dimensional lookup tables. When the speed and voltage vary while maintaining a constant ratio and constant torque, the transition threshold does not change. Consequently, the controller remains in the same mode.
