The invention relates to a new energy automobile pedestrian warning device sound system and a control method. The new energy automobile pedestrian warning device sound system comprises a microphone, an amplifier I, a filter II, an arithmetic unit, a main control unit, a filter II, an amplifier II and a loudspeaker. The microphone is connected with the arithmetic unit through the amplifier I and the filter II; the arithmetic unit is connected with the main control unit; the main control unit is connected with the loudspeaker through the filter II and the amplifier II; the main control unit is also connected with the CAN transceiver, and the CAN transceiver is connected with the input interface; the system further comprises a power management unit. According to the new energy automobile pedestrian warning device sound system and the control method, the decibel value of the surrounding environment of the automobile is collected in real time and fed back to the pedestrian warning device so as to be used for judging whether the volume of the sound emitted by the pedestrian warning device needs to be increased/decreased or not, change the volume of the warning sound emitted by the pedestrian warning device and improve the alertness of pedestrians; the effectiveness of the pedestrian warning function is enhanced, and the driving safety is improved.

    本发明涉及一种新能源汽车行人警示装置声音系统及控制方法,新能源汽车行人警示装置声音系统包括麦克风、放大器Ⅰ、滤波器Ⅱ、运算单元、主控单元、滤波器Ⅱ、放大器Ⅱ和喇叭;麦克风经放大器Ⅰ、滤波器Ⅱ与运算单元相连;运算单元与主控单元相连;主控单元经滤波器Ⅱ、放大器Ⅱ与喇叭相连;主控单元还与CAN收发器相连,CAN收发器与输入接口相连;还包括电源管理单元。本发明新能源汽车行人警示装置声音系统及控制方法通过实时收集车辆周围环境的分贝值,反馈到行人警示装置中,用于判断是否需要增大/减小行人警示装置发出声音的大小,改变行人警示装置发出的警示音大小,提高行人的警觉,增强行人警示功能的有效性,提升行车安全。
