Active sound gain and driving condition matching calibration method and system

Abstract

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 suddenly change at the same time, adjustment can be conducted through real-vehicle debugging matching after parameter setting, parameters only need to be modified on a chart, setting after recalculation is not needed, program running space is saved, and calculation timeliness is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle active sound wave sound gain calibration, and in particular relates to a method and system for matching the active sound wave sound gain with driving conditions. Background technique [0002] The ASD active sound technology receives the vehicle CAN signal in real time through the built-in algorithm of the sound module, synthesizes the sound data and sends it to the speakers in the car to simulate the sound of the engine. On traditional fuel vehicles, sound waves can be enhanced based on the original engine sound, while on electric vehicles, due to the lack of engine sound, it is necessary to simulate engine sound, which has a wide range of application scenarios. [0003] For the simulated sound waves, because different cars have different dynamics, in addition to designing the sound itself, it is also necessary to carry out calibration on the real car to match the sound with the power of the real ...
