With the rapid development of automobiles, especially more and more electric vehicles on our road today, Acoustic Vehicle Alerting System (AVAS) has increasingly caught our eyes as it plays an important role.

Designed to help solve a large concern with the near-silent travel of electric cars and some hybrid vehicles at low speeds, an acoustic vehicle alerting system (AVAS), also known as artificial noise devices, takes effect whenever a battery-powered car is driven forward or in reverse. That lack of noise, good from an environmental standpoint in terms of reducing the din generated by motor vehicles but also with serious safety implications for pedestrians and other road users. Specific conditions also trigger the system.

When a car is running at low speeds (in some regions and regulation this specific speed value may have only slight differences), the Acoustic Vehicle Alerting System kicks in under normal driving conditions. For instance, an electric vehicle traveling slowly down a residential street or parking lot at the shopping mall in pickles time as well school zones with walkers will produce some kind of noise. The sounds and information provided by many of the vehicles models ^ systems signs, may look quite different alike. A specific tone sounds like a legacy ICE idling at low speed, to comfort pedestrians; others are simply intermittent chirps that may catch the ear of someone not paying attention; some will be warning signs customized by their manufacturer. These notifications are always being played via speakers placed in the front and rear of the vehicle body. What it does is generate noise so that pedestrians, cyclists, children and other more unprotected road users know the vehicle arrives which should prevent possible accidents.

Apart from the common scenarios above, the acoustic vehicle alerting system is also frequently required to work when vehicles are in reverse. It usually at this time makes a more distinctive and louder sound to help people around it clearly understand that the car is backing up. Very important in ensuring safety 2-especially car parking and a narrow road.

Now let's review the regulatory need for an acoustic vehicle alerting system. The regulations have been deployed by several nations and places. The European Union has made it mandatory for all new electric cars and also some hybrids from 2019, this system. The United Nations also set standards for quiet road transport vehicles. Existing rules in the US similarly mandate the use of AVAS on electric vehicles. The rules are aimed at addressing safety gaps generated because electric vehicles were too quiet.

The report also predicts that the acoustic vehicle alerting system will get smarter and more personalized in future as technology improves. This might allow it to tailor the volume and type of sound to the conditions like, for example traffic flow. It could soon be using vehicle-to-everything (V2X) tech to converse with pedestrians' smartphones for alerts that are hopefully more useful.
