Because electric vehicles produce very little sound when driving, this was initially promoted as an advantage. However, over time, it was gradually realized that the low driving sound of electric vehicles could actually be a disadvantage, as it often makes it impossible for pedestrians to hear the vehicle. Therefore, experts have developed a low-speed warning sound system for electric vehicles, with the aim of allowing pedestrians to perceive the approach of the vehicle in a timely manner through the warning sound emitted by the system.

According to experts, "Electric vehicles, lacking the engine noise of traditional cars, can pose challenges for vulnerable groups such as the blind or visually impaired. When driving at low speeds in town centers and parking lots, electric vehicles emit even less sound. Therefore, we have developed the Audible Vehicle Alert System specifically for electric vehicles to ensure the safety of all road users. We are delighted to have the support of a core charity for the visually impaired to ensure that the core of our product testing is targeted at those who truly need it.". ”
According to the engineers, they have been developing the low-speed warning sound system for electric vehicles for four years and have successfully created a sound that can be heard but not from inside the vehicle. Initially, they aimed to produce a sound resembling that of a sci-fi spaceship, but as vehicles approached, the sound emitted by the electric vehicle's low-speed warning sound system led pedestrians to look up at the sky in search of the source, rather than towards the road. Before settling on this particular sound, the engineers conducted tests in an anechoic chamber (a specialized soundproof room) and various urban settings. The warning sound of the electric vehicle's low-speed warning sound system emanates from a speaker located on the front grille of the car, audible from all directions, and continues to sound continuously.

1. When the vehicle is stationary, there is no warning sound; when the vehicle speed is less than 20km/h, the low-speed warning sound system of electric vehicles will increase with the increase of vehicle speed;
2. When the vehicle speed is greater than 20km/h and less than 30km/h, the low-speed warning sound system of the electric vehicle decreases as the speed increases.
3. When the vehicle speed exceeds 30km/h, the prompt sound will automatically stop.
4. When the vehicle is in reverse gear, it will emit a continuous and uniform warning sound. Regardless of whether the vehicle is moving forward or in reverse, the warning sound will automatically stop when the engine is started.
