Nowadays, the application of low-speed warning sound systems for electric vehicles is not limited to us. Even foreign countries have issued relevant regulations, emphasizing the importance of installing low-speed warning sound systems on electric vehicles. Indeed, the sound emitted by electric vehicles, especially at low speeds, is too small and dangerous for pedestrians on the road. Therefore, it is imperative to install low-speed warning sound systems for electric vehicles.

In the newly launched "Technical Conditions for Motor Vehicle Operation Safety", it is explicitly stated that "when the speed of new energy vehicles is below 20km/h, a sound warning should be issued to remind everyone that the vehicle is driving." The newly launched low-speed warning sound system for electric vehicles will automatically start when the vehicle speed is below 30km/h; The sound increases with the speed of the vehicle between 0-20km/h, and decreases with the speed of the vehicle between 20-30km/h; When the engine is started, the working speed range of the electric vehicle low-speed prompt sound system is greater than 0km/h and less than or equal to 20km/h. When the vehicle is stationary, if the drive system is still in "drivable mode", the electric vehicle low-speed alert sound system can emit a sound. The prompt sound automatically stops. In addition, the low-speed warning sound system of electric vehicles can be controlled to turn on and off by operating the buttons on the dial.
In addition to our country, the United States and Japan have also introduced relevant regulations to protect pedestrian safety. The National Highway Traffic Safety Administration (NHTSA) has mandated that starting from September 1, 2019, all electric vehicles sold on the market must automatically emit a sound to alert pedestrians when traveling at speeds below 18.6 miles per hour (approximately 30km/h). Japan has mandated that all hybrid and electric vehicles produced after March 2018 must be equipped with a vehicle proximity notification device to ensure pedestrian safety.
The so-called "electric vehicle low-speed warning sound system" refers to the parts or components installed on electric vehicles that can emit sound containing some sound pressure level and frequency information when the vehicle speed is in a low-speed state, that is, 0 to 20 kilometers per hour, to alert other road users.
When electric vehicles operate at low speeds in pure electric mode, the average external noise is significantly reduced compared to traditional internal combustion engine vehicles. The working speed range of the Weishan electric vehicle low-speed prompt sound system is greater than 0km/h and less than or equal to 20km/h. When the vehicle is stationary, if the drive system is still in "drivable mode", the electric vehicle low-speed alert sound system can emit a sound.
