Active sound gain and driving condition matching calibration method and system

The invention discloses an active sound gain and driving condition matching calibration method and system, and the system comprises a boundary data obtaining module and a calibration module, the boundary data obtaining module is used for obtaining accelerator pedal opening degrees P1-Pn when a vehicle runs at a constant speed at a plurality of vehicle speeds V1-Vn, the calibration module is used for calibrating active sound gains corresponding to different vehicle speeds and different accelerator pedal opening degrees according to the relation between the vehicle speeds V1-Vn and the accelerator pedal opening degrees P1-Pn, wherein the relation is obtained by the boundary data obtaining module. According to the method and the system, active sound gain amplitude distinguishing under various working conditions is achieved only through the two parameters of the vehicle speed and the pedal; the gain can be adjusted at will under various working conditions, it is guaranteed that the gain is continuous and does not
