La International Automobile Federation (FIA) believes that advanced driver assistance systems (ADAS) have several aspects to improve before being mandatory for new cars in Europe. In this context, the entity has made a series of recommendations to the European Parliament, collected in the report "How to maximize the benefits of ADAS for road safety?" with the aim of maximizing the benefits of these systems for road safety, taking into account their functions, limitations and knowledge by users.
The European Parliament regulated in May 2019 a set of ADAS technologies that must be present in all new cars from July 2022 (and in all existing models by 2024). For the FIA, since these systems are going to be mandatory, it is crucial that they work perfectly and that drivers and users are well aware of their operation and limitations.
The FIA has conducted extensive research on six of these systems: Automatic Emergency Braking (AEB), Intelligent Speed Assist (ISA), Emergency Stop Assist (ESS), Adaptive Cruise Control (ACC), Maintenance Assistant lane (LKS) and fatigue warning (DM). The objective of the research was to answer the following question: "What policy recommendations can be made to maximize its benefits?" And these have been the conclusions ...
LEARN MORE ABOUT ITS FUNCTIONS
End users do not have a clear explanation of the limitations of the ADAS nor on the operating conditions under which they are designed. There is a risk that users do not know when the system should or should not act and when it will automatically activate or deactivate.
The accuracy of operation of ADAS systems is not yet entirely satisfactory. There are too many times when the wizard does not behave as expected and this affects trust in the system by end users.
BETTER ERROR-SAFE COMMUNICATION
ADAS systems can experience malfunctions that pose a potential safety risk, but these systems almost never warn the driver of their malfunctions. The result is that drivers are always waiting for the assistance of a security system, and sometimes it will not act. The inability of the driver to react to a traffic situation due to the false expectations placed on the system can be a cause of an accident.
The man-machine interface of ADAS systems must react and behave predictably, and the driver must be informed of any malfunction.
CLEAR MAINTENANCE AND CALIBRATION PROCESSES
We must ensure transparent processes of maintenance and calibration so ADAS systems remain effective over time. 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 of the ADAS systems have to be recalibrated to ensure that they provide accurate information to the security systems. This recalibration must be carried out by professionals with the appropriate training, experience, methodology and technology.
MORE EDUCATION AND TRAINING
Most drivers do not receive training on ADAS systems, only the information provided by the car dealer, the user manual or applying the "trial and error" method. Neil greig, the FIA's director of policy and research, believes that “Much more emphasis needs to be placed on driver education to make better use of technology. Vehicle manufacturers and dealerships are the key, as they must ensure that when a customer leaves the dealership they understand and correctly use the various security systems ”.
MORE ACCESSIBLE AND UP-TO-DATE ASSESSMENT PROCEDURES
Currently, ADAS operation cannot be checked through vehicle OBD and there is no clarity on the life of the systems. It is necessary to establish clear regulations to guarantee the useful life of the ADAS and a periodic review to evaluate the correct operation of each system, which could be part of the annual technical inspection. Manufacturers should make the information on these systems available to independent workshops so that the repair and maintenance process is transparent.
AN INTEGRATED AND SAFE SYSTEM APPROACH
You need a integrated and multi-channel approach “Driver-vehicle-infrastructure” to take advantage of and increase the safety potential of ADAS. With regard to the vehicle, minimum technical requirements must be established and all ADAS must comply with the same regulations. In terms of infrastructure, national road operators and traffic authorities should work together to achieve a "future-proof" road network.
