The invention discloses a pedestrian warning sound simulation sounding device for low-speed driving of an electric vehicle. A driving state setting module is used for setting the driving state of theelectric vehicle; the signal simulation module is used for converting the received driving state setting signal into a driving state signal to realize simulation of the driving state of the electric vehicle; the controller module is used for processing pre-stored audio data matched with the received driving state signal to generate a corresponding audio signal; the sound production driving moduleis used for carrying out power amplification on the received audio signal so as to drive the loudspeaker to produce pedestrian warning sound; and the display is in signal connection with the driving state setting module to display the driving state information in real time. According to the invention, the driving state of the electric vehicle can be simulated in the static state of the vehicle andthe pedestrian warning sound in the corresponding state is driven to be emitted, so that the test and subjective evaluation of the pedestrian warning sound are completed in a test room and the interference of external noise on the pedestrian warning sound is avoided.

    本发明公开了一种用于电动汽车低速行驶的行人警示音模拟发声装置其中,行车状态设定模块用于设定电动汽车的行车状态;信号模拟模块用于将接收到的行车状态设定信号转化为行车状态信号,实现对电动汽车行车状态的模拟;控制器模块用于对与接收到的行车状态信号相匹配的预存音频数据进行处理,生成相应的音频信号;发声驱动模块用于对接收到的音频信号进行功率放大,进而驱动扬声器发出行人警示音;显示器与行车状态设定模块信号连接,以实时显示行车状态信息。本发明能够在车辆静止状态下模拟电动汽车的行车状态并驱动发出对应状态的行人警示音,从而实现在试验室内完成行人警示音的测试及主观评价工作,避外界噪声对行人警示音的干扰。
