This is the most striking problem regarding electric vehicle engines: Silence!

So why this silence and why are they so quiet? security problem Does it create?

Why do electric vehicles drive quietly?

Electric vehicle engines use a completely different technology than combustion engines. combustion engines, It moves the pistons due to the burning and exploding of the fuel. This makes the engine make a distinct sound while running.

However, the situation is different with electric vehicles. vehicles, works with electric motors and electrical energy is transferred directly to the engine. In other words, since there is no explosion or combustion process, the engine makes no noise.

In other words, electric motors have far fewer moving parts. In combustion engines that run continuously many parts rub against each other While electric motors run silently with direct current.

This means that only the tires are in contact with the road while the vehicle is moving. a light humming and wind sound It allows you to hear. While the silence that electric vehicles provide is a very attractive feature for many people, it also brings with it some safety concerns.

What are the risks of silence?

Although silence may seem like an advantage at first, it can pose problems in terms of pedestrian safety. Special visually impaired persons, They often rely on the sound of the engine to determine when a vehicle is approaching.

The silence of electric vehicles can make them difficult to spot on the road may lead to an increase in the number of accidents. In addition, children and the elderly may have difficulty noticing the approach of electric vehicles because they hear traditional vehicle sounds and feel safe.

These concerns have been recognized in many countries around the world and have led to the introduction of various regulations. For example, the European Union has announced that the number of electric vehicles will increase in 2019. Makes artificial engine noise at low speeds has passed a law making this mandatory.

Similarly, in the United States, electric vehicles For rides under 20 km/h There are rules that state that it must produce an artificial sound. In addition, the necessary sound minimum 56, maximum 75 decibels it should. The sound should be audible from a distance of 2 meters.

These sounds depend on the speed of the vehicle. with a changing frequency It was designed this way so that pedestrians and other road users can more easily understand the speed and distance of the vehicle.

Silence has no benefits!

Silence offers both great benefits and safety issues. One of the biggest problems of city life is in reducing noise pollution Electric vehicles play an important role.

Imagine hearing the engine sound of every vehicle in heavy traffic… A world full of electric vehicles sounds better. peaceful Isn’t he coming?

In addition, this silence offers a very pleasant experience for owners of electric vehicles. Quiet driving without being disturbed by engine noise is a big plus for many drivers, especially during long journeys. Therefore, electric vehicles provide urban silence and in terms of driving comfort It is strongly preferred.

Is a calm but safe future possible?

While the silence of electric vehicles may initially raise some safety concerns, there is a solution to this problem. Various solutions are being developed started.

Artificial sound technologies Thanks to regulations and guidelines, these vehicles are designed to protect both the peace of mind that silence brings and ensure the safety of pedestrians.

When pedestrians and cyclists end up in the lane of oncoming traffic automatic braking function It is now found in many electric vehicles. With the development of collision avoidance systems and autonomous emergency braking systems, the safety risk of electric vehicles is also being minimized.
