Active vibration noise control system

Abstract:

An active vibration noise control system is applied to a vehicle provided with an EPS motor to change behavior of the vehicle. The active vibration noise control system includes an ANC processor configured to receive acoustic information at a predetermined position in a vehicle compartment as an error signal and control a vibration noise based on a reference signal correlate with the vibration noise and the error signal that is received and an inverse electromotive force information receiving section receiving information on an inverse electromotive force induced on the EPS motor by behavior change of the vehicle. The ANC processor utilizes as a reference signal the information on the inverse electromotive force received by the inverse electromotive force information receiving section. The active vibration noise control system actively controls the vibration noise generated in the vehicle.
