Holistic Safety & Security Considerations
Increasing complexity and connectivity increases the challenges of a consistent security argumentation and secure IT infrastructure. Added to this are new methods for a modular safeguarding process and the self-assessment of automated driving systems at runtime.
In autotech.agil, we are working on a comprehensive safety assessment for future mobility systems. Using a safety-by-design approach, hazards and the resulting risks are considered at the overall system level and addressed with the help of a safety concept. This allows potential weak points and causes of hazards to be identified at an early stage, making the overall system robust and reliable. A comprehensive safety argument supports communication about residual risks, both between those involved in the development process and with the public.
Modular and Continuous Validation
Changes in the mobility system of the future will require automatic software updates at short notice during operation. Although service-oriented architectures enable the exchange of individual modules, new challenges arise for the safety argument and the homologation process. In autotech.agil, we are therefore developing new modular validation approaches to support the agile development process. The potential increase in testing effort and the replacement of tests at vehicle level with module-specific test platforms are addressed by the close integration of automated and scalable simulation methods, which ensures continuous and efficient safety approval.
Secure IT Infrastructure
In view of the growing interconnectedness and digitalization, a secure IT infrastructure is crucial. This includes protection against cyberattacks and ensuring data integrity and availability. The secure IT infrastructure forms the backbone on which the various networked components can communicate securely with each other and is therefore essential for confidence in automated mobility systems. In autotech.agil, we are also developing approaches for integrating safety and security engineering.
Self-Monitoring and Self-Assessment
Reliability and safety require that automated vehicles continuously monitor all of their abilities while performing the driving task. To do this, they must assess whether the driving task can still be performed safely in the current operating mode. In response, a modular software architecture can be used to reconfigure the system in an agile manner or to intelligently degrade it.
Overall, our project highlights the important contributions that a comprehensive security analysis and a secure IT infrastructure can make to overcoming the challenges of increasing complexity and networking of the mobility system. We present approaches for communicating and dealing with residual risk for the introduction of automated driving as part of mobility concepts.
