In the past, major car manufacturers aimed to reduce and further decrease the driving sound of cars, attempting to achieve a "silent" state and use it as a selling point to attract customers. But now electric vehicles have achieved low-frequency driving, and the sound emitted is almost inaudible when driving at low speeds. However, people have objections because low-frequency electric vehicles are not perceived by the public and can easily cause accidents. Therefore, the low-speed warning sound system for electric vehicles has emerged.

Both electric vehicles and hybrid vehicles operate in pure electric mode when starting at low speeds, as the electric motor runs very quietly, just like the silence after a teacher gets angry in class. Therefore, many people are completely unaware of the starting and driving of electric vehicles outdoors, especially those young "low head enthusiasts", which may result in collisions with electric vehicles, ranging from serious injuries to the inability to find contact lenses. Perhaps many people have been scared by electric vehicles coming unnoticed on the road. Nowadays, many new energy electric vehicles have very quiet motors, and some car manufacturers even intentionally "mute" the starting sound.
The quiet start combined with the fast acceleration of electric vehicles has led many people to suggest that low-speed pure electric vehicles should add an electric vehicle low-speed warning sound system to make pedestrians and vehicles aware. This suggestion has also received attention from government departments. Therefore, on January 1st of this year, the "Technical Conditions for Motor Vehicle Operation Safety" were released, which suggested that "new energy vehicles should emit sound warnings when the speed is below 20 kilometers per hour to remind everyone that the vehicle is driving." That's right, it is recommended that those new energy vehicles that run purely on electric vehicles at low speeds can be equipped with electric vehicle low-speed warning sound systems.
The implementation of this policy shows the importance attached by relevant departments to such issues, and also suggests that car manufacturers pay attention to the driving safety of electric vehicles. Nowadays, many vehicles are equipped with electric vehicle low-speed warning sound systems. The electric vehicle low-speed warning sound system is configured to automatically start when the vehicle speed is below 30km/h. When the vehicle speed is between 0-20km/h, the volume of the electric vehicle low-speed warning sound system increases with the increase of the vehicle speed, and when the vehicle speed is between 20-30km/h, the volume of the electric vehicle low-speed warning sound system decreases with the increase of the vehicle speed. Moreover, the low-speed warning sound system of Weishan electric vehicles can be manually controlled to turn on and off.
 
Having read through the previous text, I wonder if you have gained a better understanding of the low-speed alert sound system for electric vehicles, which was born to address the issue of low bass in electric vehicles. Regarding more small information, we will continue to collect and organize it for you in the future, so please pay close attention to our latest developments in order to obtain details as soon as possible.
