They forced cars to incorporate automatic emergency braking at 60 km/h. It has not been enough, so in the US they are going to expand it by law to 144 km/h

From June 2023 here in Europe, all cars must equip automatic emergency braking (AEB) by lawsomething that did not happen in USA: there were no regulations as such that required the use of this assistive technology. This is going to change and also, It will be stricter than the European oneas they will have to brake at higher speeds.

This regulation, which has just become effective, will require that from 2029 all new cars that are sold in the US incorporate this technology in the terms defined by this new regulation.

Effective in the city, but not so much on the highway or highway

In 2016, Manufacturers in the US committed to installing automatic emergency braking as standard in their cars from 2022. This was an agreement, but never a regulation as yes it has been in Europe. In part, this has served as a trial period to verify the effectiveness of this system and to be able to define by law what it should be like.

“The technology is already mature enough to be mandatory in all vehicles. But we are doing much more than that,” said Ann Carlson, senior advisor at NHTSA. when the final regulation was formally defined in spring.

The main deficiency that has been detected in this system already equipped by the brands is that At low speeds it does its job well. But not so much at medium or high speeds.

For example, This study the American Automobile Association (AAA) concluded that did not avoid a single head-on collision at high speeds. A situation that occurs on conventional roads with only one lane in each direction and which accounts for 40% of those killed in accidents there. Here too, these types of collisions are the most recurrent with fatalities in the equation, along with road departures.

Automatically brake up to 144 km/h when a collision is imminent. This new regulation requires that cars be able to brake themselves at high speeds.in addition to correctly detecting vulnerable users (pedestrians/cyclists) both day and night.

Specifically the cars They will have to stop and avoid a collision against another vehicle at a speed of up to 100 km/h. But in addition, AEB systems must activate the brakes automatically at speeds up to 144 km/h when a collision with another vehicle is imminent and up to 72 km/h when detecting a pedestrian or cyclist.

This means that cars brake on their own at any speed at which they can travel, since the maximum limit in the US is up to 75 mph (129 km/h), which applies on highways and expressways.

Thus, car brands are going to have to improve their current systems and comply with these speed ranges. In Europe, emergency braking by law must be done up to 60 km/h, although there are cars that apply it at higher speeds. In essence, it has focused more on avoiding accidents in the city.

This could also affect cars sold on this side of the pond. Since making different technologies is not profitable, many cars sold on both continents will meet these standards, braking automatically at higher speeds.
