Functional Safety

With Fraunhofer you will encounter great acceptance in the certification process

We are familiar with the major safety standards (esp. IEC 61508 and its domain-specific derivations such as ISO 26262, ISO 25119, or ISO 13849) and have extensive experience regarding the assurance of functional safety in different domains and under a wide variety of project constraints. As a Fraunhofer Institute, we are an internationally recognized, independent authority whose solutions are also widely accepted by regulatory authorities.

We help you to manage the risks of future systems

In line with our mission of applied research, we are particularly concerned with safety challenges of future systems. Ever higher levels of automation combined with ever greater interconnection and the increasing use of Artificial Intelligence – all these aspects lead to uncertainties and unknowns, which are difficult to address on the basis of established techniques, methods, and standards.

Here we offer an innovative solution with our dynamic risk management approach. Systems are enabled to assess risks on their own at runtime and, based on this assessment, to implement those measures that guarantee both an acceptable residual risk and the best possible performance. Since no standards have yet been established for the safety assurance of autonomous systems, in particular, we support our customers with our extensive knowledge on existing standardization activities, in which we also participate ourselves.

Our many years of experience in model-based safety engineering techniques, methods, and tools (safeTbox) will help you to efficiently and effectively assure the safety of your current systems. Our novel research approaches can be the crucial enabler to bring your innovative systems of tomorrow to market with outstanding performance, verifiable safety, and a clear conscience!
