What are Adas: Automatic emergency braking

There Automatic emergency braking or AEB (Autonomous Emergency Braking) is a compulsory security device (therefore standard) on all New cars registered in Europe starting from July 2024. AEB has been an Adas of crucial importance since 2019, when the European legislator with the 2019/2144 regulation has put it on a par with other devices such as the ABS (the braking anti lock) or the ESP (stability control) which are considered fundamental for active safety, therefore mandatory for years and now data for granted. Automatic emergency braking is not the only one of the Adas (advanced driving help systems) which have been recently made on new registration cars, but among these it is One of the most useful and effective to protect pedestrians and cyclists that among the users of the road are among the most vulnerable.

What is and how it works

–

Automatic emergency braking is based on two elements: one camera in the upper part of the windscreen (usually close to the internal rearview) and a radar integrated into the “muzzle” of the car. The information from both is processed by the “brain” of the EEB for Determine the distance Between the car and the vehicle preceded, any vehicles that could end up in trajectory following a change of direction or that could take in the street, a vehicle stopped in trajectory or even pedestrians and cyclists. If, considering speed and distance, the AEB recognizes a situation of potential dangerThen send a sound warning to the driver (and often also visual, through the dashboard) to report the danger; If the alarm is ignored, the car brakes alone to avoid a collision or mitigate the consequences if the impact is inevitable. There are AEBs that act only at the low speeds typical of urban contexts and others, more advanced, which can also operate on the highway.

It doesn’t go to the subtle

–

AEB – that the car manufacturers each call in a different way – is help to driving in itself quite precise, provided that “eyes” and camera surfaces and radar are sufficiently free from dirt, mud or snow. Otherwise, however, the on -board system asks to intervene to restore the functioning of the EEB, precious both in the case of distractions behind the wheel and of very poor visibility, think of the fog or a strong downpour in the evening. Can reduce the consequences of an oversight, but It was not born to replace the driver. In short: there is, it is useful, but it is not designed to continually curb the car instead of the driving. Also because it is an emergency device, which does not go too much for the subtle: when it comes into action most of the time nailed.
