N2 - The paper describes the usage of the electrical power steering (EPS) motor as an actuator to perform active noise cancellation in passenger cars. Therefore, the existing field oriented controller for the motor current is modified and the demanded currents required for the power steering are superimposed with additional signals e.g., sinusoidal signals with frequencies of 50-500Hz that generate vibrations of the motor. These vibrations are transferred as sound and vibration to the drivers cabin. Adaptive filters are used to shape the steering motor vibrations such that they cancel narrowband disturbance sounds at the position of the drivers ear. The concept is experimentally validated in a vehicle where a narrowband acoustic disturbance generated by a shaker on the front axle carrier is canceled.
