Title:
NEW ENERGY VEHICLE AND ACTIVE NOISE REDUCTION METHOD AND SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/019801
Kind Code:
A1
Abstract:
Provided are a new energy vehicle and an active noise reduction method and system therefor, so as to solve the problem in existing active noise reduction methods for new energy vehicles wherein at the same time that a motor noise signal is subject to compensation, other non-motor noises are interfered with, thereby forming a new enhanced noise signal, which results in a negative effect on the improvement of acoustic environment quality. In the active noise reduction method for the new energy vehicle, a noise reduction construction signal is generated by not only considering the frequency of the motor noise signal, but also comprehensively considering the magnitude of the acoustic pressure levels of other non-motor noises and the motor noises in the acoustic environment.
