The automotive industry is constantly growing in the development of security systems for the evolution of each of the models that come out on the world market. Probably the greatest progress on this issue was the inclusion of advanced ADAS (Advanced Driver Assistance Systems) driving assistance systems that are available in the vast majority of new vehicle generations that are being presented all over the world.
This technology, complex to understand for the common user of a car, brings together a set of systems that are characterized by providing assistance to the driver to increase safety and facilitate handling.
Some ADAS simply inform the driver of surrounding circumstances. Others alert you to a risky situation, for example, that there is a large speed difference with the vehicle in front of us or that we are stepping on the lane demarcation line. When the driver ignores these warnings, there are systems that can even take control of the brakes and / or the steering of the vehicle to avoid a collision or at least reduce its consequences.
For example, a vehicle that equips the autonomous emergency braking system can stop on its own if it considers that there is an imminent risk of collision. That ability to drive automatically makes some ADAS the forerunners of autonomous driving.
Among all this set of assists, we can name Adaptive Cruise Control, Adaptive Speed Limiter, Lane Keeping, Blind Spot Warning, Forward Collision Warning, Lane Departure or Unintentional Lane Departure Warning, Rear Cross Traffic Alert and Automatic Emergency Braking; but there are many others.
We already know them and we know what they are but now we tell you everything you need to know about this great evolution in the automotive industry so that When choosing a new model, take safety into account first. of each of the vehicles to choose from.
1. How do they work?
ADAS systems have “eyes” (cameras, radar, ultrasound and lidar, mainly) that collect information based on their technical capabilities. For example, cameras recognize colors and have a wide range of 50 to 500 meters, and up to 180º; Y recognize people, animals and objects through algorithms of their software and artificial intelligence. The radar, however, locates static and moving objects in the surroundings of the vehicle, and determines their relative speed, distance and position.
All the information collected is sent to the control unit of the system, which merges all this data and generates a reliable recognition of the vehicle’s environment: the road, other vehicles, pedestrians, animals or signaling. This information is contrasted with data on the movement of the vehicle itself (speed, situation, acceleration, braking, turning) and with the actions of the driver, to detect risky situations and act accordingly, either by alerting or taking control.
2. How effective are the ADAS?
There are no doubts in the automotive industry that with driver assistance systems were able to help drive safer and reduce the incidence of human error. In fact, thanks to them, the accident figures will be significantly reduced as they gain presence in the general fleet of vehicles.
In Europe, it is estimated that with the proposal of mandatory ADAS systems from 2022, 25,000 deaths on the road can be avoided in the next 15 years. According to a study by the German Insurance Companies Association (GDV), claims for claims will be reduced by 25% in 2035, compared to the figures of recent years, thanks to the effectiveness of the ADAS. The reduction in accidents will be thanks to autonomous emergency braking, which will prevent a large number of collisions, and the lane change and maintenance assistants, which will “avoid” many accidents on expressways due to unmarked lane change maneuvers.
3. When will these security systems be mandatory?
Most of the models on the market can equip, as standard or optionally, some of these systems. In the old continent, all vehicles sold from the year 2022 must be equipped as standard with devices such as an intelligent speed assistant, a black box, an emergency braking signal or a reversing detector. And in the following years more systems will be introduced.
Regarding the obligation in our region, it is still delayed. For example, In South America it is still struggling to incorporate stability control (ESP) that has already been postponed several times and now it would only be for January 2022. The ADAS? Although many models on the market already bring it as a series element, the requirement of this system is not yet under analysis.
4. Do they need maintenance?
From the user’s point of view, these systems do not require any special attention or maintenance, beyond keeping the area of the windshield where the cameras are housed clean. Official services or authorized workshops can electronically detect that there are no faults in the systems.
In the event of an accident that affects any of its elements, after the repair the cameras and sensors will have to be recalibrated so that they work correctly, something that especially affects the windshield. When a new one is replaced and installed, the cameras and sensors have to be adjusted to ensure proper operation.
5. Can ADAS systems fail?
ADAS systems can experience malfunctions because their cameras and sensors have not been recalibrated, or that operation has been done incorrectly, after the replacement of a windshield.
When sensors fail due to poor calibration, the vehicle is not able to reliably recognize the environment and the security systems are unresponsive., which can lead to an untimely emergency braking or, worse, a serious accident.
