The invention provides a driving prompt sound generation method and system, electronic equipment and a storage medium, and belongs to the field of electric automobile loudspeakers. The method comprises the steps that the current vehicle speed is obtained according to a detected signal sent by an ignition coil in a vehicle; judging whether the current vehicle speed is smaller than a preset vehicle speed threshold; if yes, a low-speed prompt signal corresponding to the change of the vehicle speed is called according to the current vehicle speed; judging whether a pre-stored whistling signal is received or not; if yes, performing frequency band adjustment processing on the low-speed prompt signal and the whistling signal; synthesizing the low-speed prompt tone and the whistling tone by adopting a pre-stored flash program to obtain a synthesized tone; and the synthesized sound is amplified and played through a loudspeaker outside the vehicle. According to the method and the device, the driving prompt tone generated in the vehicle under the low-speed condition can meet the smoothness of the low-speed prompt tone and can also meet the high sound pressure of the whistling sound, and the two sounds do not interfere with each other, so that the recognition of pedestrians is facilitated, and the occurrence possibility of traffic accidents is effectively reduced.

    本发明提供了一种行车提示声生成方法、系统、电子设备及存储介质,属于电动汽车扬声器领域。该方法包括根据检测到的车辆中点火线圈发出的信号获取当前车速;判断当前车速是否小于预设车速阈值;若是则根据当前车速调取随车速变化所对应的低速提示信号;判断是否接受到预存的鸣笛信号;若是对低速提示信号及所述鸣笛信号进行频段调整处理;采用预存flash程序将低速提示音及鸣笛音进行合成得到合成音;将合成音进行放大处理并通过车外扬声器播放。通过本申请,在低速情况下车内生成的行车提示音即可满足低速提示音的平顺性,又可满足鸣笛音的高声压,且该两种声音不会相互干扰影响利于行人的识别,有效的降低交通事故的发生可能性。
