driving safety. Avoid traffic accidents with the help of technology. To this end, the European Commission last year proposed that cars of the future have ADAS systems, driver assistance systems that will reduce accidents. Its goal under the slogan Vision Cero: save over 25,000 lives and prevent 140,000 injuries by 2038. And by 2050, the goal is to reduce the number of deaths and serious injuries to almost zero.

It all starts this year 2022, in the month of July. As reported General direction of travel (DGT) during the past year, “all vehicles must be equipped with eight driver assistance systems (ADAS) as standard.” Automated driving safety to avoid accidents. Specifically, the commitment will apply to “new vehicles approved in Europe from 2022 and new vehicles sold from 2024.”

ADAS is an acronym for Advanced driver assistance systems, in Spanish, Advanced driver assistance systems. The idea is that the car actively assists the driver. While driving safety measures such as seat belt or airbag focus on protect people during an accident ADAS systems want avoid those accidents before they happen. This protects the driver, passengers and pedestrians.

ADAS systems are mandatory from 2022

eight ADAS systems driving safety, which should be included in European cars approved from this year and will become mandatory for new cars sold from 2024. Its function avoid accidents by helping the driver through technology.

list of ADAS systems following:

  • Intelligent Speed ​​Assistant (ISA)
  • Rear camera with cross-motion detection
  • Lane Departure Warning (LDW)
  • Fatigue and/or sleepiness detector
  • Emergency braking system BAS and EBA
  • Car lock with breathalyzer
  • Black box (EDR)
  • Rear seat belt warning

smart speed assistant

We talked about the first one last year, when the General Directorate of Road Traffic announced it. According to its official journal, “ISA is a system that connects the adaptive cruise control (ACC) with the signal recognition system via software, controlling its position on the road. regarding the speed limit which governs each section. In particular, “the car uses cameras, radar and GPS in combination with a digital map.”

Unlike speed limiter, the ISA system automatically adapts to the track section. You don’t need to program it in advance. In both cases, the driver cannot exceed the specified limit.

Rear view camera with traffic detection

rear cameraobviously, helps to maneuver backwards. But it has more benefits. They help to park and exit, warn if there is an obstacle, stationary or moving, or a person at a distance of less than 30 meters. On some models, you can stop the vehicle before colliding with obstacles or other vehicles or being run over.

This ADAS system can use 360 degree camera. In some cases they intersect red arrows on the screen indicate the direction of the potential hazard. Otherwise, there are progressive sound warnings and, finally, the activation of the brakes.

Lane Departure Warning

LDW system (Lane Departure Warning) warns you if you have inadvertently changed lanes. Using a camera in front of the rearview mirror or sensors, the car determines the lines that define the lane. distances from 60 to 100 meters.

According to the official DGT journal, “in addition to helping, an evolution of this technology is the LKA (Lane keeping assistance) or LCAS (Lane Keep Assist), a active lane keeping system that, faced with the possibility of leaving the trajectory limited by lines, can turn the steering wheel or, in some vehicles, interfere with the stability control system (ESP) by acting on the brakes and on the wheels opposite those that are in a straight line.”

Fatigue and/or sleepiness detector

To prevent the driver from falling asleep at the wheel and therefore losing control of the vehicle, this ADAS system performs the following functions: detect fatigue. To do this, he has two safety measures behind the wheel. First, the steering wheel itself. And second, the camera. According to the Main Department of Road Traffic of the city of St. 20 to 30% of accidents They arise directly or indirectly due to driver fatigue.

There is a sensor on the steering wheel. analyze pressure supplied by the driver. As well as hand movements and direction changes. If it detects permanent fixes or sudden movements, it will activate. As for the camera, follow facial featuresespecially eyes and head movement. This system can also control the running time of the engine. After two hours of driving or if any malfunction is detected, the vehicle gives a light signal on the dashboard.

emergency braking system

ALS is an abbreviation for Brake Assist and EBA means Electronic Brake Assist. In fact, this is the same technology with two different names. This brake assistant allows you to shorten the reaction distance and is linked to two vehicle systems that have been standard on the car for many years: ABS and stability control.

How it works? Previously, with the help of sensors, it detects obstacles that are in front of us. Distinguish between pedestrians and other elements. With light and sound warning, driver notified. When we brake hard or the tread intensity is high, the system determines if this intensity is adequate. If not, the system applies the maximum braking intensity until we take our foot off the pedal. That is, if you do not respond to the warning, braking is activated automatically. He also tightens the seat belts.

This is an emergency braking system in case of unforeseen obstacles. operates at speeds from 5 to 40 kilometers per hour, common in residential and/or urban areas. More modern systems also activate at higher speeds.

Car lock with breathalyzer

According to the National Institute of Toxicology, in 2019, 45.5% of drivers who died in road accidents who underwent an autopsy gave positive for alcohol, drugs and/or psychotropic drugs. These data, collected by the official journal of the General Directorate of Traffic, confirm the importance of this ADAS system.

From 2022, vehicles homologated in Europe must have a pre-installed breathalyzer. In addition, it will include start blocking car, which will be activated in case of exceeding the allowed limits. In particular, it analyzes the rate from 0 to 2.5 mg per liter in a maximum time of 25 seconds.

Information will appear on the car screen. It must have Internet access via Wi-Fi and memory to store 100,000 tests. According to the DGT, this system “includes fingerprint recognition, pupil, face detection or digital photos stored in memory to always identify the user and prevent fraud“.

black box

Starting this summer, European cars will have black boxes, a safety device behind the wheel that is already being used on airplanes. EDR is an abbreviation for Event data logger, translates to event data logger. Its task is to record more than 15 variables, in addition to the day and time.

These variables are “vehicle speed, braking, engine speed, frontal and side impact force, steering movements, accelerator position, safety systems such as airbags, belts or certain assistants”, etc. With this data, it is supposed to get the best analysis in the event of an accident to improve driving safety introducing new technologies and improving those that we already use today.

In particular, the black box will record data for 30 seconds before crash or loss and for 5 seconds after. Using a computer, data can be retrieved from the black box for analysis and investigation of the event.

Rear seat belt warning

Near one of the most implemented measures for the new cars we mentioned earlier. The rear seat belt warning is self-explanatory. Show visual warning on the dashboard if any of the seat belts is not fastened correctly, if that seat is occupied. The warning is also usually audible.

Depending on the model, this ADAS system is activated when the vehicle is in motion or when it starts to move and exceeds 25 kilometers per hour or more time has elapsed than necessary for Fasten seat belts.

Please note that the seat belt mandatory for the driver since 1974 and for rear seats since 1992. However, such a basic security system is still not used, especially by passengers. Otherwise, rear seat belts are sometimes supplemented by rear or side airbags, depending on the vehicle.
