ADAS systems: what they are
When we talk about “ADAS system” we mean advanced electronic systems such as, among many others, rain sensors, twilight sensor, adaptive cruise control, automatic emergency braking, parking sensors, lane change warning or automatic signal recognition. All of these devices are installed in newly type-approved cars to minimize the risk of accidents and make life in the car easier.
Safety systems: zero-risk cars
The car ADAS system includes, mainly, the control systems that we indicate below:
Cruise Control: ACC
Adaptive cruise control (ACC), that is speed control, is one of the most appreciated car ADAS because it allows, after setting the desired cruising speed and the preferred safety distance, to let the car drive autonomously. Thanks to this device, the car will accelerate and brake according to the traffic conditions and the driver will have the possibility to relax in the driver’s seat while keeping the situation under control.
Of all the car safety systems now available on the latest small cars, frontal and rear collision warning is undoubtedly the most popular ADAS system. Thanks to the presence of a camera or an auto radar located in the front area, the ADAS safety system recognizes dangerous situations and warns the driver with an acoustic signal. The rear collision warning system operates in the same way in the event of a rear-end collision, and prior to impact activates the safety systems to prepare the occupants of the car for the collision.
Other car safety systems that are becoming increasingly popular on modern cars are those related to lane keeping. In this case, too, the vehicle’s brain interacts with the cameras and radars placed on the car and recognizes the demarcation line of the roadway, warning the driver when he crosses it. A concrete example comes from freeway use, where the ADAS system intervenes when the driver crosses the line of the road without having first used the direction indicator. The most advanced ADAS lane keeping system is the Lane Keeping System, which not only warns the driver of a lane departure but also automatically brings the vehicle back into the lane.
ADAS systems mandatory from 2022
As of 2022, ADAS, the safety and driver assistance systems, will become mandatory throughout Europe. Thanks to the agreement reached in Brussels, all new vehicles will have to have automatic emergency braking or lane keeping as standard. The agreement will have to be examined by all EU member states before being submitted to Parliament and the Council of Ministers.
The new regulation envisages the introduction of around thirty advanced electronic systems that guarantee the safety of drivers and passengers. A large part of the requirements will be met by the launch of new models on the market, as early as May 2022. Cars already on the market will have to comply by May 2024.
Different types of ADAS systems will be available on newly registered cars, such as: emergency braking assistance, drowsiness recognition and alertness threshold, lane keeping, emergency stop signal, reversing camera or proximity sensors, reversing detection system and integrated breathalyzer preparation for driver’s blood alcohol level.
Intelligent Speed Assistance or Adaptive Cruise Control is another important technology which, by analysing road signs and satellite maps, adjusts the speed of the vehicle according to the limits.
Another innovation could be the presence of black boxes on board, for the memorization of the phases immediately preceding an accident.
As far as testing is concerned, and in order to increase the level of safety, the new regulation could foresee different types of crash tests, other provisions for requesting tire approval and finally different specifications for windscreens, such as to reduce the consequences in case of an accident.
As for heavy vehicles, such as trucks and buses, these will have to ensure greater visibility and introduce blind spot monitoring or collision warning systems.
Prevention and safety
The decision to introduce mandatory ADAS is linked to estimates made by the European Commission that these driver assistance systems could prevent around 25,000 deaths and 140,000 injuries on European roads between 2022 and 2038.
To those who may be wondering whether ADAS would reduce the cost of
To those who may be wondering whether ADAS will increase the cost of cars, the EU is responding by making available a ceiling of 450 million euros to be granted to Member States to cooperate in the implementation of the regulation, thus avoiding the increase of list prices.
