Integrated Active Noise Control System for Low-Frequency Noise in Automobiles
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
Two types of active noise control (ANC) technologies were developed. One is ANC for engine booming noise and the other is ANC for drumming. We have adopted these technologies into many mass production vehicles. However, these two ANC technologies are not able to be integrated because of both interference between two control systems and the issue on stability of a feedback controller. The purpose of this paper is to propose a new control algorithm for ANC for drumming which enables to be combined with ANC for engine booming noise. The newly developed system is the first commercialized ANC in the world and is applied to Sports Utility Vehicle and Sedan model.
