[0001] The application belongs to the technical field of new energy vehicle design, and particularly relates to a new energy vehicle three-in-one loudspeaker control method and system and a vehicle. BACKGROUND

[0002] Vehicle noise, especially the noise emitted by vehicles approaching pedestrians, can immediately attract the attention of pedestrians, making them aware that a vehicle may be approaching, thereby increasing their alertness. This alertness is crucial for pedestrians as it helps them to react quickly and avoid potential traffic accidents. Through the reminder of vehicle noise, pedestrians can more accurately judge the position, speed and direction of travel of the vehicle. This information is crucial for pedestrians as it helps them make the right decisions, such as whether to cross the road, whether to change their walking route, etc. This noise-based traffic safety reminder helps to reduce the occurrence of traffic accidents and protect the safety of pedestrians.

[0003] However, current electric vehicles have cancelled the engine and transmission system, and the noise generated during driving has been greatly reduced. In order to remind pedestrians of safety, electric vehicles are equipped with AVAS alarm functions. However, this function is a single device that is added separately, increasing the cost of individual vehicles and devices. In addition, electric vehicles are becoming more and more intelligent and scenario-based, in order to meet various use scenarios and customer needs, vehicles are equipped with external loudspeakers.
