When buying a vehicle, the user will be increasingly aware of the ADAS (Advanced Driver Assistance Systems) systems, since all new cars and vans launched on the European market from now on must incorporate these mechanisms driving aid. The objective of making this new technology mandatory is to reduce the number of deaths on roads within the European Union by 25,000 by the year 2038.

According to data from the General Directorate of Traffic (DGT), during the month of July (in full exit operation) 122 fatal accidents have been registered on Spanish roads in which 131 people have diedthat is, 14 more victims than in the same month of 2019. From Traffic they assure that this increase is due, to a greater extent, “to the increase in the number of displacements” which has risen 5%. Specifically, throughout the month 45.2 million long-distance movements were registered, compared to 43.3 million July 2019.

In this context, the incorporation of ADAS system technology can significantly help curb the accident rate and, more importantly, can save the lives of all vehicle occupants, since it reduces the risk of an accident. Specifically, according to the VIDAS project, ADAS systems “would be capable of preventing 40% of accidents37% of injuries and up to 29% of fatalities”.

Even so, according to the sociological study Knowledge of ADAS systems by the Spanish population, framed in the VIDAS project (road safety and ADAS), promoted by Bosch and the Federation for Road Safety (Fesvial), the 40% of Spanish drivers You acknowledge that you do not have sufficient knowledge about this type of safety and driving support systems. At the same time, the remaining 60% state that they do know them, but they would not know how to provide a specific definition and are confused about the different elements and their functions.

With regard to the degree of equipment in the Spanish fleet, Bosch and Festival they describe it as “medium-low”, especially in that technology that has the ability to avoid road accidents, such as lane maintenance systems, automatic emergency braking, blind spot steering or fatigue detectors, among others. others.

How do they work?

ADAS systems need to create reliable knowledge of the vehicle’s surroundings in order to detect these risky situations and be able to offer assistance to the driver. In other words, they generate a virtual photograph that provides information to the system’s control unit, data that arrives through various sources. In this sense, Carglass has prepared a report on the operation of the different ADAS technologies:

cameras

This could be said to be the star component of the system and they are usually installed in the upper central part of the windshield. These cameras, with the help of different algorithms and artificial intelligence, are capable of offering reliable recognition of pedestrians, animals and objects or reading traffic signs. Of course, these elements can only “understand” what has been previously classified in their software.

Another of their problems is that, despite being very sophisticated, they can cause vision problems when they get dirty or there are weather conditions such as rain, fog or snow. In addition to natural optical illusions.


Radar

This element is usually located on the front grille of the vehicle and serves as a support for locating objectsboth static and in motion, that are around the vehicle while it is running.

The range of the radars is in 250 meters and have a 360 view of the environment. Their advantages are that they are not affected by inclement weather and measure all relevant values ​​(angle, distance, speed and parameters) without the need for calculations. The disadvantage is that they are not able to recognize colors, shapes or objects.




laser lidar

This system “is an expensive and complex sensor,” they say from Carglass. But it will be key to future autonomous driving. The LIDAR (Light Detection and Ranging) laser can accurately measure in 3D at a range of 200 meters away. The problem is that, to work properly, it needs the support of other sensors, because its range is reduced when there is fog, rain or when it is dirty.

ultrasound

These components are installed in the bumper of the vehicle and “are very reliable.” They work with a technique similar to that used by bats to fly, using ultrasonic pulses that bounce off objects and the echoes are analyzed to obtain information. “Of course, they only serve for driving assistance systems related to vehicle parking, since they have a range of six meters and only work at low speeds,” says the Carglass report.

Navigation system

The great advantage of this element is that it does not depend, like sensors, on a certain range. The digital cartography is already registered, which allows you to generate a virtual horizon with the marked route in which slopes, curves or speed limits appear. This helps the vehicle’s predictive cruise control systems predict braking and accelerating based on road terrain, among other things.

new systems

At the beginning of the 1980s, the only ADAS technology incorporated in vehicles was the ABS, airbag, traction control… elements that are already very much incorporated into people’s vocabulary. On the other hand, there are currently around thirty new elements that assist driving and many of them are already incorporated as standard in the new vehicles. These include, for example, the intelligent speed system, which is capable of detecting signals and adapting the speed according to the limit marked on each road.

On the other hand, it is the fatigue alert. According to the DGT, between 20% and 30% of traffic accidents are related, in one way or another, to fatigue, so what this element does is determine when the driver should stop. To do this, it uses cameras or sensors located inside the cabin to analyze the movements of the driver or his eyes and warns him with an acoustic signal that tells him to stop.




Added to this are automatic braking light systems, which turn on when the car applies emergency braking to warn rear vehicles of the danger that is added to rear traffic detection, which warns if there is something behind the vehicle. when leaving a battery car park and, the most interesting, the alcolocka system that requires the driver to prove that they do not have high levels of alcohol in their blood before starting the vehicle.

It is true that technology helps save lives, but ADAS security systems are not presented as the solution to accidents, but as an aid to reduce the numbers. The human factor and respecting traffic regulations are essential for road mortality to decline.
