An automotive control system includes a controller for use with an inverter configured to drive a traction motor with electrical energy from a traction battery. The controller is programmed to select a base switching frequency for a control signal for the inverter such that a switching noise sideband frequency of the inverter is the same as a harmonic frequency of the traction motor, modify the selected base switching frequency by a random switching frequency to obtain a modified switching frequency, and control the inverter with the control signal having the modified switching frequency for the inverter to drive the traction motor.
