The invention particularly relates to a sound control method giving consideration to both low-speed pedestrian warning tones and electronic sound waves of an electric vehicle, and the method comprises the steps: controlling a basic sound source which is the low-speed pedestrian warning tones and the electronic sound waves meeting the requirements; the method specifically comprises the steps that the vehicle speed and the opening degree of an accelerator pedal are selected as independent variables of sound control, and sound frequency components and the overall sound pressure level in a basic sound source serve as dependent variables of sound control; the vehicle speed influences the sound frequency component and the overall sound pressure level, the opening degree of the accelerator pedal only influences the overall sound pressure level, the vehicle speed is set as a first-level control parameter of sound, the opening degree of the accelerator pedal is set as a second-level control parameter of the sound, and the overall sound pressure level change caused by the opening degree of the accelerator pedal is superposed on the basis of the effect of the first-level control parameter; the overall sound pressure level is set to linearly change along with the change of the opening degree of the accelerator pedal and linearly change along with the change of the vehicle speed, and the variable quantity of the overall sound pressure level along with the opening degree of the accelerator pedal and the variable quantity of the overall sound pressure level along with the vehicle speed are superposed.
本发明具体涉及一种兼顾电动车低速行人提示音和电子声浪的声音控制方法，本方法对基础音源进行控制，基础音源为满足要求的低速行人提示音和电子声浪；方法具体为：选取车速和加速踏板开度为声音控制的自变量，将基础音源中的声音频率成分和整体声压级作为声音控制的因变量；车速对声音频率成分和整体声压级都有影响，加速踏板开度只对整体声压级有影响，将车速设置为声音的1级控制参数，将加速踏板开度设置为声音的2级控制参数，加速踏板开度引起的整体声压级变化在1级控制参数效果的基础上进行叠加；设定整体声压级随加速踏板开度的变化而线性变化，整体声压级也随车速的变化而线性变化，整体声压级随加速踏板开度的变化量和随车速的变化量叠加。
