Calibration method, device and vehicle

Abstract

The application provides a calibration method and device and a vehicle, and relates to the technical field of noise control. The method comprises the following steps: determining an ambient noise signal, wherein the ambient noise signal is used for indicating noise in a first environment, the first environment comprises N secondary sound sources and M secondary sound sensors, N and M are positive integers; controlling the N secondary sound sources to send excitation signals according to the ambient noise signal, and obtaining NXM acquisition signals collected by the M secondary sound sensors, wherein the excitation signals and the ambient noise signal satisfy a first signal-to-noise ratio; and determining NXM secondary paths according to the N excitation signals and the NXM acquisition signals. Based on the scheme, the accuracy of secondary path calibration for multiple ANC systems can be effectively improved. The scheme can be applied to new energy vehicles.
