Sorigué ends its involvement in research on a redundant road safety system for self-driving vehicles
October 6, 2022
The findings of the study show that the autonomous driving magnetic system developed by the joint venture between Elecnor and Sorigué, with the help of the Polytechnic University of Catalonia, can be used for self-driving vehicles in zero visibility conditions without any support systems provided there is no traffic.
After two years of research, the joint venture between Elecnor and Sorigué has finished developing technology based on magnetic markers for increasing the preventive safety of self-driving vehicles on roads. The findings show the system to be robust, reliable and scalable to real sizes and speeds, although to avoid collisions with other vehicles a radar or similar system is also necessary.
The research project, under the title “Development of a Redundant Road Safety System for Self-Driving Vehicles, Smartmove”, was funded by the Government of Catalonia’s Business Competitiveness Agency ACCIÓ, under the tender “Industrial Research and Experimental Development Groups” and the RIS3CAT strategy.
Developed by Elecnor y Sorigué, this project is budgeted at €892,468.41. It also featured the collaboration of the Laboratory for Technological Innovation of Structures and Materials (LITEM) of the Polytechnic University of Catalonia (UPC).
Self-Driving Vehicle Safety
Self-driving vehicles feature obstacle detection mechanisms that use cameras.However, there are numerous risk situations brought on by the weather (fog and rain), local visibility (tunnels), and uncertainties when making decisions (intersections, roundabouts) etc., which make zero-risk safety impossible.
This means that when faced with adverse circumstances, vehicles need a redundant safety system that is not affected by their vulnerabilities and positioned directly on the road to provide local information on the vehicles’ exterior.
This research has responded to this need. The integration of this on-road driving system was designed using a construction system that correctly positions the magnetic straps on the road, with Firflex, a synthetic binder, working to ensure these straps are attached and secure. This opens a line of research for developing a new type of Firflex with a built-in continuous marker, which will make it easier to add a marker on the road.
