Abstract
Disclosed are an active noise reduction method and device for a vehicle, and a storage medium. The active noise reduction method includes the following steps: generating two reference signals according to a target noise to be denoised; generating a control signal and sending it to a sound reproduction device; filtering the reference signals to obtain filtered reference signals; calculating a noise signal; updating an auxiliary control parameter; calculating an updated auxiliary control parameter-based error signal; and updating the control parameter. The method actively reduces the noise of vehicle engines, reduces interior noise pollution, and has a fast convergence speed.
