摘要
近年来,电动汽车的数量日益增多,为保证汽车使用安全,文章将以电动汽车低速提示音装置为研究对象,利用频率响应测试系统,对提示音装置的频率进行分析.并将频率响应得到的测试数据进行整理,以此来评价、判断提示音系统的特征.同时,加强系统的应用,真实反映系统低速提示音的特点,生成声音频谱特征,为系统功能的发挥提供依据.
Abstract
In recent years,the number of electric vehicles is increasing.To ensure the safety of automobiles,this paper will take the low-speed prompt device of electric vehicles as the research object,and use the frequency response test system to analyze the frequency of the prompt sound device.The test data obtained from the frequency response are collated to evaluate and judge the characteristics of the prompt sound system.At the same time,the application of the system is strengthened,the characteristics of the low-speed prompt sound of the system are truly reflected,and the characteristics of the acoustic and audio spectrum are generated,which provides a basis for the function of the system.
