Newly designed or converted vehicles need to obtain a registration according to the ECE Regulations in order to operate in public traffic areas. Furthermore, standards of functional safety such as DIN EN 61508, ISO 26262 and DIN EN 50126 have to be observed in the course of the vehicle design process. In addition to providing legal security, working with these and further standards ensures state-of-the-art procedures and the development of standardized, market-ready products.
The Fraunhofer IVI includes the individual views of users, designers and technical monitoring organizations in the development of new technologies. In order to achieve this, the institute's researchers rely on their strong connections and long-standing experience gained in numerous field tests executed for users and transport providers. Further important factors that provide a solid basis for future developments relevant to safety and registration are in-house test stands, frequent collaboration with universities and the successful set-up and launch of various systems.
The Fraunhofer IVI has completed ample work in safety-relevant areas such as high-voltage vehicle systems (1000 V AC, 1500 V DC) and braking and steering systems. Some features included in this work are system description, identification of hazards caused by the system and risk classification (SIL classification). The results are presented in tabular format using tools such as Failure Mode and Effects Analysis (FMEA) and Failure Tree Analysis (FTA) in the process. These tools allow the matching of measures to concrete components, as well as the derivation of testing tasks. The overall aim is to develop simple and efficient measures, preferably using established methods described within the ECE Regulations or other standards. Both the measures and the complete system need to comply with the ECE Regulations at all times.
Within the development process for market-ready state-of-the-art products, the Fraunhofer IVI is able to take over the task of system analysis and planning, as well as to administrate and/or support the set-up and launch procedures. In this respect, the collaboration with technical monitoring organizations is one of their strong points.
