23rd DVR-Forum

ADAS for trucks should not be switched-off

In June, experts discussed safety and mobility topics on the 23rd forum organized by the German DVR (traffic safety) association. This included manipulations of ECUs.

Trucks are equipped increasingly with advanced driver assistance systems (ADAS). In the last years, manipulation of electronic control units (ECU) is significant. According to several sources, the number of manipulated trucks is about one fourth. In particular, the CAN-based tachographs are manipulated. The ISO 16844 series standardizes the CAN-connectable tachographs. Andreas Marquardt, president of the German BAG (Bundesamt für Güterverkehr) association for freight traffic, said that the number of ECU manipulations is worrying. He spoke about manipulation 4.0 meaning that the ECUs are attacked via the CAN networks. Using magnets to manipulate tachographs is not more state-of-the-art, he said.

On the 23rd Safety and Mobility forum DVR president, Dr. Walter Eichendorf, requested that just of few ADAS systems should provide the ability to be deactivated. As example, he mentioned the lane departure assistant, which might be switch-off on road construction sites. Other systems like adaptive cruise control (ACC) and forward collision warning systems (FCW) should always be activated. Such systems are necessary to achieve the five stars if the Euro NCAP rating. By 2018, advanced emergency braking (AEB) and lane departure assistance systems will become mandatory for new trucks in Europe.
