The so-called "low-speed driving sound device" means that when the vehicle is in a low-speed state, that is, 0 to 20 kilometers per hour, it can emit a sound containing a certain sound pressure level, frequency information to prompt other road users of parts or components.

Necessity of Integrated AVAV03

When the vehicle is driving at low speed, the average noise outside the vehicle is obviously lower than that of the traditional internal combustion engine vehicle, which makes it difficult for other road users, including pedestrians, bicycles, etc., especially blind people and people with visual impairment to detect the approaching of the vehicle and easily lead to traffic accidents. In view of the safety of vehicles at low speeds, a great deal of research and discussion has been done in recent years by NHTSA, MLIT and WP29 of UNFXE. It is unanimously determined that warnings should be provided for vehicles with low speeds. Tip sound device to reduce the probability of traffic accidents with pedestrians. In order to avoid accidents caused by too quiet, it is necessary for domestic automobile manufacturers to formulate technical standards for low-speed driving warning sound, improve the vehicle's perception under low-speed driving conditions, enhance the safety performance of vehicles, and effectively protect the personal safety of other road users, including pedestrians.
