The invention relates to the technical field of electric vehicles, and particularly relates to a method and system for realizing active sound production of a vehicle based on a vehicle-mounted intelligent terminal. The method comprises the steps of pre-storing multiple segments of audio files in the vehicle, wherein each segment of audio file is associated with an accelerator pedal opening degreerange and a motor rotating speed range; and receiving an accelerator pedal opening degree signal and a motor rotating speed signal, searching an associated audio file according to the range to which the accelerator pedal opening degree belongs and the range to which the motor rotating speed belongs, and outputting the audio file. Existing hardware configuration of the vehicle-mounted intelligent terminal is utilized, implantation and calling of a calibration audio file are matched, and the active sounding function of the vehicle is achieved under the condition that the hardware cost is not increased.

    本发明涉及电动车技术领域,具体涉及一种基于车载智能终端实现车辆主动发声的方法及系统,包括在车内预存储多段音频文件,且每段音频文件均关联有一个油门踏板开度范围和电机转速范围;接收油门踏板开度信号和电机转速信号,根据油门踏板开度所属范围和电机转速所属范围寻找其关联的音频文件,并将所述音频文件输出。利用车载智能终端现有的硬件配置,配合标定音频文件的植入与调用,在不增加硬件成本的条件下,实现车辆主动发声的功能。
