In the European Union taken 3r3196. the law, in accordance with which cars with electric motors will equip the systems of sound warning of pedestrians. The speakers will automatically turn on at a low speed of the car to warn others about its approach. We tell you what other countries have introduced such laws and why this is important. 3r3204.

3r3391. Why did you need the law r3r392. 3r3204.  
Electric vehicles move in space almost silently: these cars are powered by batteries, there are fewer moving parts in their power plants, and there is no exhaust gas distribution mechanism. 3r3204.  
3r3204.  
When an electric car rushes at high speed, its approach can be heard because of the noise of the wind and the rustling of tires. But if it moves slowly, for example during parking, not even everyone who is ten meters away will hear it. 3r3204.  
3r3204.  
3r3111. According to 3r340. Study 3r3196. Charity Association for Helping Blind Guide Dogs, for a pedestrian the risk of being hit by an electric car or a hybrid car is 40% higher than the probability of being hit by a car with an internal combustion engine. 3r33112. 3r3204.  
These calculations are confirmed by experiment 3r3196. University of California at Riverside. Scientists found that at a vehicle speed of 8 km /h, the distance between the pedestrian and the “hybrid”, from which the first could correctly determine where the car was moving from, was 74% shorter than in the case of a car equipped with an engine. Simply put, to react, a person has more time in stock, when a regular car participates in a traffic situation. 3r3204.  
3r3204.  
3r3391. What did the EU accept
3r3204.  
The European Commission adopted a law that requires manufacturers of electric vehicles and "hybrids" to raise the level of noise emanating from these cars at low speeds. 3r3204.  
3r3111. According to the new regulations, when driving more slowly than 20 km /h, the car should automatically turn on the pedestrian audible warning system. It will be required for all cars with an electric engine, and drivers will not be able to turn it off. 3r33112. 3r3204.  
The law will come into force on July ? 2019. By that time, all new car models will have to provide warning systems. The rest of the fleet is being upgraded gradually: the document does not indicate the dates for updating “old” electric vehicles, but it is 3r361. scheduled 3r3196. . 3r3204.  
3r3204.  
3r3391. Where else did these laws adopt r3r392. 3r3204.  
Similar rules for car manufacturers 3r3r71. developed 3r3196. in USA. The act was considered in Congress from 201? but was signed only at the beginning of 2018. 3r3204.  
3r3204.  
Additional sounds of electric vehicles in the United States will emit at a speed of less than 30 km /h. According to the law, by September 201? automakers must install warning systems on half of their new cars with electric engines. It is expected that all electric vehicles in the country will deliver the system by 2020. 3r3204.  
3r3204.  
By that time, according to the US Department of Transportation, the new requirements for electric cars will prevent about ?400 accidents per year. It is also assumed that these measures will save $ 250–320 million due to the reduction of aggregate damage from road accidents. 3r3204.  
3r3204.  
In Japan, the law prescribing the installation of pedestrian acoustic warning devices in electric vehicles and hybrid cars has been in effect since 2010. Devices make a sound similar to the noise of an internal combustion engine - they turn on automatically when the speed is
below 20 km /h . 3r3204.  
3r3204.  
3r3391. What will happen next 3r3392. 3r3204.  
In the US and Europe, the aforementioned bills were not supported by activists who oppose noise pollution. According to Les Blomberg, the founder of the non-profit organization Noise Pollution Clearinghouse (Les Blomberg), the problem of the “invisibility” of electric cars is not that electric motors are too quiet, but an increased level of street noise. 3r3204.  
3r3204.  
Blomberg believes that the volume of the noisiest vehicles should be limited by law: motorcycles, buses and trucks. It is worth noting that the European Union has already adopted a similar directive. Plan to reduce the volume of engines 3-3-399. calculated
for 2016–202? and the result of its implementation is 3-333101. should become 3r3196. decrease in noise from transport by approximately 25%. 3r3204.  
3r3204.  
Other activists doubt that the laws regulating the minimum level of noise from cars without internal combustion engines are passed fairly carefully, because those substitute the notion of 3r3196. and lead to the transfer of responsibility. 3r3204.  
3r3111. It’s not the driver’s responsibility to prevent accidents, but the need for a pedestrian to ensure that he is not crushed. 3r33112. However, associations of blind people did not make such claims to the described laws. From the point of view of their representatives, it is often difficult for a visually impaired person to understand where an electric vehicle is coming from, and an audio alert system will help him orient himself when crossing the road. Before the entry into force of the requirements, automakers have to solve an important task - to determine what kind of sound the device they use to warn pedestrians will emit. 3r3204.

The company strives to outdo each other in an attempt to make the sound of their cars unique. For example, the Nissan Presented 3r3196. own version of "audio" for an electric car, which is more like the sound of loading a computer than the roar of the engine. From the "melody" Nissan significantly differ "3r3134. rumble "Toyota Prius and" mystical music 3r3196. »Chevrolet Volt, which is
compare 3r3196. with sounds from video games. 3r3204.  
3r3204.  
In European countries, politicians are working on a single standard for the sound of cars without ICE. For example, in the UK electric cars 3r3r144. will sound 3r3196. as a cross between white noise and tonal noise (with a predominance of a certain frequency). But the US Department of Transportation
planning for 3r3196. to allow the use of different sound alert options in electric vehicles, from which drivers will be able to choose the signal according to their taste. 3r3204.  
3r3204.  
However, as 3r3152. Writes Futurism, differences in the "sound" of cars from different manufacturers and different models threaten to confuse pedestrians who are accustomed to the noise of an internal combustion engine. It will be especially difficult for blind people: in the absence of uniform standards, they will need to memorize a large number of electric vehicle sounds. So, perhaps, the new norms in their current form could rather harm people who should be helped. 3r3204.
